SECTION INEWBORN SCREENING FOR INBORN ERRORS OF
METABOLISM and INHERITED DISORDERS
WHY IS THIS REPORT IMPORTANT?Newborn Screening is an essential, preventive public health program. Each of these components of the system
requires ongoing monitoring to ensurequality.
This report explains significant changesduring 2002 and 2003 that occurred toNebraska’s newborn screening system,greatly expanding the number of disordersscreened, and the State’s capacity to ensurequality.
The goal of newborn screeningfor metabolic and inheriteddisorders is to identify newbornsat risk for certain metabolic,endocrine, hematologic, and otherdisorders that would otherwise beundetected until damage hasoccurred, and for whichintervention and/or treatment canimprove the outcome for thenewborn.
4
Newborn Screening is a system. It is notjust the laboratory test. It involves manyelements including:• education of health care professionals
and parents• proper and timely collection of quality
specimens • appropriate and timely transmittal of
specimens to the NBS laboratory • rapid quality testing methods • timely notification of the infants
physician • timely retrieval of the infant for
confirmatory or repeat testing;appropriate referral to specialistsfamiliar with treatment for these raredisorders
• assuring access to needed specializedservices and treatment

BIOTINIDASE DEFICIENCY:Six infants with profound or treated-partial biotinidase deficiency. (Two in2002, four in 2003). Biotinidase deficiencyleft untreated can result in nerve and braindamage and mental retardation.
CONGENITAL PRIMARYHYPOTHYROIDISM:Twenty-six infants with congenitalprimary hypothyroidism (CPH). (15 in2002, 11 in 2003). CPH left untreated canresult in mental retardation, various degreesof growth failure, deafness and neurologicabnormalities.
GALACTOSEMIA:Two infants with Galactosemia (Oneclassical and one treated Duarte MixedHeterozygote). (Both identified in 2003). Infants with galactosemia may have liverdysfunction, neurological findings ofirritability and seizures, poor feeding, failureto thrive and possibly death. Left untreated,the child who survives the neonatal periodoften will have cataracts, cirrhosis andmental retardation. Identified and treatedearly, these outcomes can be avoided.
PKU:Six infants with classical phenylketonuria(PKU) or treated hyperphenylalaninemia. (Two in 2002 and four in 2003). Patientswith undiagnosed / untreated PKU haveprogressive developmental delay in the firstyear of life, severe mental retardation,seizures, and autistic-like behavior.
HEMOGLOBINOPATHIES:Eleven infants with sickle cell disease orother clinically significanthemoglobinopathy. (Six in 2002, and fivein 2003). The sickling hemoglobinopathiescause lifelong hemolytic anemia with acuteand chronic tissue damage secondary to theblockage of blood flow produced by theabnormally shaped red cells. Clinicaloutcomes can include painful crises, sepsis,infections, splenic sequestration, and stroke.
MCAD:One infant with MCAD. (Identified in2002). Patients with undiagnosed MCAD(Medium Chain Acyl CoA DehydrogenaseDeficiency) are at risk of metabolic crises,severe disability or death when blood sugarsbecome dangerously low during fasting orillness. Preventive measures are highlysuccessful in avoiding these effects.
SUPPLEMENTAL SCREENING:One infant with an organic acid disorder(3-Methylglutaconyl-CoA HydrataseDeficiency ) identified on the supplementaltandem mass spectrometry panel.
Fifty-three ( 53 ) babies werespared the effects of disordersscreened, thanks to earlyidentification and treatmentfrom blood-spot screening in2002 and 2003.

WHAT IS NEWBORN SCREENING?
Newborn screening programs have been around for over four decades in all 50 States and in
several countries. The compulsory screening panel varies from state to state but the overall goal
is the same. This goal is to detect serious disorders for which effective treatment is available in
time to begin treatment and prevent the effects of the disorders. Depending on the disorder,
effects can range from brain and nerve cell damage resulting in severe mental retardation, to
damage to the child’s liver, spleen, eyes, physical growth retardation, stroke and even death.
Some of these effects may occur in hours to days, depending on the underlying disorder, while
others may take weeks or months or even years to show clinical or developmental signs.
Newborn screening is initiated by collecting a blood specimen from a simple heel stick directly
on to special filter paper. The filter paper blood spots are shipped to the newborn screening
laboratory and tested for several disorders. When a specimen is “presumptive positive” for a
disorder, the physician is notified and has the infant come back for a confirmatory test. Once a
diagnosis is made, treatment can begin. Treatment varies depending on the disorder and for
some, intervention may be recommended upon learning the initial screening result, prior to
obtaining the confirmatory results. Some examples of treatment are: parent education for
recognizing signs/symptoms of metabolic crisis, restricting certain foods from the diet, taking a
particular vitamin or medication, supplementing a restricted diet with special foods and formula,
or preventive antibiotic treatment. Whatever the treatment, the consequences of not beginning
treatment in time can be extremely serious for the infant and the family.
The disorders screened are rare, so the Newborn Screening Program always recommends
consultation with and/or referral to the appropriate pediatric specialist such as a Geneticist.

The Newborn ScreeningSystem for LaboratoryTesting In 2002, 69 Nebraska birthing hospitals sentspecimens to either Regional PathologyServices at the University of NebraskaMedical Center (UNMC) in Omaha, orQuest Diagnostics, Inc. in Lincoln to betested for 5 mandated disorders. (The federalhospital at Offutt Airforce Base sent theirnewborn screening specimens to a thirdlaboratory out of state.)
By July of 2002, a change in the lawgoverning Newborn Screening addedMCAD to the required screening panel. Since no Nebraska laboratory had thetandem mass spectrometry instrument toscreen for MCAD, alternative plans weremade by individual hospitals with the helpof Regional Pathology Services and QuestDiagnostics, Inc. to obtain this testingelsewhere.

From July 2002 through the end of June2003, the 69 hospitals collected secondinitial specimens and sent them to one oftwo out of state laboratories to meet therequirement of testing for MCAD. Somewent to the Institute of Metabolic Disease atBaylor University Medical Center for fullspectrum testing by tandem massspectrometry. For parents that chose not toreceive the full spectrum results, the secondinitial specimen was sent to the Iowa StatePublic Health Laboratory to screen forMCAD-only via tandem mass spectrometry. By July 2003, the Department of Health andHuman Services had entered into acontractual agreement with NeoGenScreening Laboratory LP, (later acquired byPediatrix Screening) and all hospitals begansending every newborn screening specimento this laboratory in Pennsylvania.

PART II
MAJOR INITIATIVES of 2002 and 2003
Education
The program significantly revised the patient education booklet using full-colorphotos, and simplified the reading level while expanding the information to betterinform parents. The booklet was field-tested and parent survey results yieldedgenerally positive comments. (Parent Survey results initiating these changes can befound in the appendix of the State Plan athttp://www.hhs.state.ne.us/hew/fah/nsp/stateplan.htm. Also see appendix in thisreport for parent reaction to the new material.) Due to the development of this newmaterial, the program was invited to present at the 2003 National Symposium inBerkeley California on Tandem Mass Spectrometry Screening Practices. Theprogram manager presented as part of two panels, one on “Patient EducationMaterials” and one on “Informed Consent.” Supplies of the full color booklets areroutinely sent by the program to all birthing facilities for inclusion in their newborninformation packets. These booklets are intended to supplement hospital andphysician education of new parents about newborn screening. The booklets areavailable in English and Spanish.
A Physician Information Sheet and Patient Fact Sheet were developed for MCAD. The NNSP faxes these sheets to the newborn’s physician when notifying thephysician of a positive MCAD screening result. The physician information sheet wasmodeled after a form developed by the Iowa Newborn Screening Program.
Several grand round presentations were conducted at hospitals across the State in2003 by Richard Lutz, MD, William Rizzo, MD and G. Bradley Schaefer, MD,pediatric metabolic specialists. A presentation was also made to the members ofAWHONN (Association of Women’s Health Obstetrics and Neonatal Nurses). Thegrand rounds covered metabolic newborn screening, emphasizing MCAD and thefatty acid, amino acid and organic acid disorders that can be identified viasupplemental newborn screening from tandem mass spectrometry.
Eleven Regional in-services were presented at nine hospitals across the state by theNewborn Screening Program Manager in the Spring of 2003 to help prepare hospitalsfor the transition to the single lab and universal offering of supplemental screening toall parents. Four physicians and 222 nursing and laboratory staff attended these in-services.
To help evaluate the effectiveness of patient education materials, a survey of newparents was conducted as part of the State Newborn Screening and Genetics Planninggrant needs assessment. Partly as a result of this assessment, the materials weresignificantly changed. (See appendix for survey results.)

Policy Development
Legislation was introduced and passed during the 2002 session (LB 235) thatwould significantly change the way screening was done in Nebraska. LB 235revised the Newborn Screening Law requiring:
Universal screening for MCAD, adding it to the mandatory newborn screeningpanel
A competitive bid process for a contract with a single lab to conduct all of thestate’s screening
Specific quality assurance compliance by the contracted laboratory
An increase from $3 to $10 of the per infant screened fee (used to support formulaand treatment)
This legislation resulted from the Department’s plan to find a cost-effectivemechanism that would ensure quality screening for carrying out the NewbornScreening Technical Advisory Committee’s recommendation to add MCAD to therequired panel. Despite expanding the panel and despite the increase in the fee, thecost of newborn screening testing was reduced by competitively bidding the contract.
The law governing Predictive Genetic Testing was revised in 2003, followingstakeholder/advisory group recommendations to clarify certain sections. LB 119introduced and passed by the 2003 legislature clarified Nebraska Revised Statute 71-1, 104 passed by the 2001 legislature. A group of stakeholders met several times andworked very hard to develop a model informed consent form for predictive genetictests. Regulations were developed. Following the regulation promulgation processincluding a public hearing held in November of 2003, the regulations became officialin February 2004. Model informed consent forms are available from the Departmentof Health and Human Services for:
Supplemental Newborn Screening
Prenatal predictive genetic testing
(Other) Predictive genetic testing
The Storage, Use, and Disposal of Residual Dried Blood Spots from NewbornScreening was addressed by LB 432 introduced and passed in 2001. The statuterequired the Department to develop regulations governing the storage, use, anddisposal of residual dried blood spots from newborn screening. A stakeholder groupadvised the Department on these regulations beginning in December 2001. TheNewborn Screening regulations were revised in 2002 to add language recommendedby the stakeholder group. Residual newborn screening dried blood spots fromNebraska newborns are to be stored for 90 days, and destroyed within 30 days

following this period. They may only be used for research when approved by anInstitutional Review Board, and when individual consent of the newborn’s parent orlegal guardian has been obtained.
A Newborn Screening and Genetics Planning Grant received from the Maternaland Child Health Bureau resulted in a needs assessment and state plan for geneticservices being developed in 2002 and 2003. The program had collaborated with theUNMC, Munroe- Meyer Institute (MMI) for Genetics and Rehabilitation in thedevelopment of the application. The Department contracted with MMI for thecoordination of this project. Shelly Nielsen, MS served as the project managerworking with the Newborn Screening and Genetics Advisory Committee.Membership included most of the Technical Committee advisors but was expanded inan attempt to gain greater consumer, minority and geographic representation. Theconsumer representation increased from one to six members, minority representationby two, and geographic representation improved with the addition of a rural familypractice physician and central Nebraska pediatrician (Academy assigned)representatives.
During the first year of the grant, this group worked to identify perceived gaps orbarriers in the service system infrastructure for newborn screening and for childrenwith special health care needs due to genetic conditions. The five infrastructure workgroups were Policy, Legislative, Data, Personnel Resources, and Financing. Thegroups identified information needs and began analysis of preliminary informationprovided, using nationally recognized guidelines (AAP) for newborn screening andgenetics.
A site visit by experts from the National Newborn Screening and GeneticResource Center was conducted in October 2003. Recommendations from this sitevisit were incorporated into the final State Plan for Newborn Screening andGenetics. Some of the recommendations have been implemented and others arebeing evaluated for ways to implement them. A copy of the State Plan can beobtained by contacting the program or as a pdf file by visiting the web site: http://www.hhs.state.ne.us/hew/fah/nsp/stateplan.htm.
In the Courts: In 2002 a family in Douglas County refused the required screeningfor their newborn. The Douglas County Court ruled the family must have the babyscreened, and the family complied. Again in 2003 another family in Douglas Countyrefused the required screening for their newborn. This case was reported in easternNebraska newspapers and news segments on television. Following requests forcontinuances, the judge ruled the family must get the baby screened. This case hasbeen appealed and will be heard in the Nebraska Supreme court. A third case (2004)in Lancaster County Court, the judge also upheld the law and ordered the baby to bescreened. The parents complied.

Treatment Services Changes
Nebraska’s longtime advocate and expert in metabolic diseases and newbornscreening, Dr. Hobart Wiltse began a well-deserved retirement in 2002. In 2002 theHobart Wiltse Institute for Metabolic Disease was dedicated at Children’s Hospital inOmaha. Coordination between Children’s Hospital and the Munroe-Meyer Institutefor Genetics and Rehabilitation at the University of Nebraska Medical Centerresulted in changes in services for newborns and children with metabolic disorders. Adults continue to be seen in the clinic at Munroe-Meyer, but newborns and children arenow seen by the UNMC pediatric metabolic specialists at the Children’s Hospitallocation.
Fortunately the Program continues to benefit from Dr. Wiltse’s many years of experienceand expertise via his involvement with the Newborn Screening Advisory Committee, onwhich he serves as the 2004 Chairperson.
Nebraska is extremely fortunate to have great expertise in Genetics, PediatricMetabolism, and Pediatric Endocrinology. The following Pediatricians, and Board-Certified Medical Geneticists are either Board Certified or Board-eligible in geneticsendocrine and metabolism:

Also staffing the metabolic clinics are outstanding allied health professionals withspecialization in the disorders of metabolism. Jill Skrabal, MS, RD, LMNT, CDE helpsadult patients and families manage the special diets through the metabolic clinic atUNMC. Ms. Skrabal also conducts all formula distribution via a contract with theDepartment of Health and Human Services. Kathryn Heldt, RD, LMNT, CDE and KathyRossiter, MSN, CDE, ARNP, CPNP, likewise work closely with the families of childrenwith PKU and other metabolic disorders in managing the challenging diets through themetabolic clinic at Children’s Hospital.
Funding sources for treatment:Federal funds allocated to Nebraska under the Title V Maternal and Child Health BlockGrant have been used for many years to support nutritional counseling and to provide specialized formulas for individuals with PKU. In addition, state general fundappropriations of $42,000 and funds generated from the per infant screened fee helppurchase the specialized formula and pharmaceutically manufactured foods necessary fornormal development and adequate nutrition for people with PKU. These funding sourcesare critical as there is no Federal Health Insurance Act or even a State Insurancerequirement that ensures coverage of the essential metabolic formula or medicallynecessary foods.
With the addition of MCAD to the mandatory screening panel in 2002 and the option forsupplemental MS/MS testing for other fatty acid, amino acid and organic acid disorders,the contract was expanded in 2003 to help with treatment costs (special formulas) forindividuals identified with these disorders screened. In addition, in 2003 it soon becameapparent the NNSP follow-up program success relied even more heavily on closecollaboration with physician specialists in metabolism. Therefore the contract for theordering and distribution of special metabolic formulas and dietary consultation wasexpanded to include part of a Pediatric Metabolic Specialist Physician’s salary. Whenabnormal screening results are obtained the pediatric metabolic specialist is on-call forconsultation to the primary health care provider, and in many cases that are urgent, thespecialist will contact the PHCP to aid with follow-up recommendations.
Families were able to order the pharmaceutically manufactured foods directly from thevendors with which Nebraska had contracts. As specified in the statute, each individualrequiring the special diet is eligible for up to $2000 of the pharmaceuticallymanufactured foods. Through these resources 44 individuals with PKU were served formetabolic and dietary consultation and formula and/or foods.
Treatment costs supported by the Nebraska Newborn Screening Program:
The contract for metabolic formula and professional nutrition management by dietitiansserved 42 individuals in Fiscal Year (FY) 02, and 47 individuals in FY 03:
FY 2002 (ending June 30, 2002) $200,255FY 2003 (ending Sept. 30, 2002-adjusted quarter due to Fed FY) $279,278
State contract expenditures to vendors for the pharmaceutically manufactured foods

ordered direct by families for 28 individuals in FY 02 and 44 individuals in FY 03 were:
FY 2002 (ending June 30, 2002) $18,829.22FY 2003 (ending June 30, 2003) $46,246.81
The significant increase in family participation in the foods program in FY 2003 isbelieved to be due in large part to significant patient education and outreach efforts ofstaff from the metabolic clinics. The metabolic clinic staff worked particularly close withwomen of childbearing age or who have conceived, to help them manage the diet.
According to the National Institute of Health (NIH) Concensus Statement onPhenylketonuria: Screening and Management (Oct/2000) “The goal in the treatment ofPKU is to maintain metabolic control of Phe for optimal adaptation and outcome. … Toachieve optimal metabolic control and outcome, a restricted-Phe diet, including medicalfoods and low-protein products, most likely will be medically required for virtually allindividuals with classical PKU for their entire lifetimes…” The diet is crucial during theearly years to prevent mental retardation, and critical during childbearing years to preventpregnancies from being affected with microcephaly and other problems. Studies havealso found that cognitive and motor functioning can be negatively affected by going off-diet.

Newborn Screening Advisory Committee
The Newborn Screening Technical Advisory Committee (NBSTAC) exists to providetechnical expertise and guidance to the Nebraska Newborn Screening Program. In 2002following the passage of LB 235, the Committee met to make recommendations forregulations to implement the changes in the Newborn Screening Law.
MCAD and regulations Spring 2002:At the Spring meetings, the Committee discussed the other disorders that may be detectedby tandem mass spectrometry (MS/MS) when screening for MCAD. They consideredwhether any of the other MS/MS disorders should be included in the mandatory panel. While the Committee concluded that many of the disorders met the criteria for inclusionin mandatory NBS panels, the decision to require them was deferred for many reasons. For one, some of the good candidate-disorders are identified by markers that are sharedwith other disorders that do not as clearly meet the criteria. As more states add MS/MSto their NBS panels, more data will accumulate. It is expected that the anecdotes ofpositive outcomes for previously thought to be untreatable disorders will become betterknown and well documented. The Committee and the Program felt the best course ofaction until more data becomes available, was to be sure the full spectrum panel would beoffered to all newborns, but to ensure it would not cost more if parents chose to receivethe results. This was accomplished via the regulations and the competitively bid contractwith the laboratory.
Quality Assurance Reviews:In 2003, the Committee continued to review quarterly quality assurance reports from theprogram. The Committee also monitored aggregate data received by the program onsupplemental screening using tandem mass spectrometry. Refer to Section III of thisreport for summaries of this data.
Further regulation revision recommendations:In the fall of 2003, the Program acted on recommendations of the Committee and a sub-work group of laboratory specialists to significantly revise the regulations. Regulationrevision began through the public process in the fall/winter of 2003. Specifications fortest methodology and cut-offs were removed from the regulations and replaced withlanguage allowing these specifications to be determined via contract with a singlelaboratory, with the advice of the Newborn Screening Advisory Committee. Theprogram management felt comfortable making the regulations more flexible once a singlelaboratory test provider system was in place with contractual obligations. Allowing suchchanges to occur through contractual arrangements vs. regulatory channels will ensureNebraska can respond more rapidly as appropriate to improvements in technology.
Consideration of new disorders for newborn screening:Screening for Cystic Fibrosis and for Congenital Adrenal Hyperplasia began receivinggreater national and grassroots attention. A national conference was held in November of2003 to present data on Cystic Fibrosis screening. The NBSAC also began discussions
Nebraska Health and Human Services System

of this topic at its December 2003 meeting. Further consideration of these disorders,pending additional data and review of service system needs will continue.
Committee Structure: A formal Charter was adopted in 2003, which reflected the broader advisory charge ofthe committee beyond the “technical” aspects into the “policy” aspects. Therefore theCommittee removed “technical” from the title and changed to the “Newborn ScreeningAdvisory Committee”. The members of the NBSAC were/are:

Healthy Mothers/Healthy Babies Connection
A critical component to any screening program is ensuring appropriate services forfamilies. As discussed in prior reports, concerns were identified that families of infantsscreened positive for hemoglobinopathies were not consistently receiving informationabout next steps to take or the availability of genetic services. The letter sent by theNNSP informing mothers when their infant has a positive screening result for ahemoglobinopathy includes the Nebraska Newborn Screening Program (NNSP) phonenumber for them to call if they have questions. The program has also developed anarrangement with the Healthy Mothers/Healthy Babies toll-free helpline. At this number(included in the letter) mothers can get information about how to reach pediatrichematologists or genetic counseling services. In addition, if they want furtherinformation, the helpline will take their name and number and have an NNSP staff member contact the mother.

Part III
NEWBORN SCREENING DATA FOR 2002 and 2003
The following data for Nebraska’s Newborn Screening (blood-spot testing) is presentedin this section in much the same sequence as newborn screening occurs. From patienteducation to specimen collection, transport and testing, to results, andintervention/treatment.
Consent/Dissent Rates for Supplemental Newborn Screening:
Education plays a major role in a parent’s choice to receive the supplemental newbornscreening results available from tandem mass spectrometry (MS/MS) when their child isscreened for the mandatory disorders using this method. Health care providers giveparents the “Parent’s Guide to Your Baby’s Newborn Screening” booklet along with the“Supplemental Newborn Screening Consent” form. The baby’s primary health careprovider is to engage in discussion and answer questions from the parents prior toobtaining the consent. The written materials were available to providers and parents in2002 and 2003. Prior to July of 2002 only seven major birthing hospitals offeredsupplemental screening for newborns. At that time approximately 34% of Nebraskabirths received MS/MS testing. In July of 2002, when MCAD became mandatory, andMS/MS thus became a required method, the additional results available from MS/MSwere consented to by about 55% of newborns’ parents. At that time it cost an additional$15 above the cost of mandatory-only testing to get the full spectrum MS/MS. Oncescreening began with Pediatrix in July of 2003 (and it did not cost more for thesupplemental vs. mandatory only), the rate of consent rose to about 95%.

The program will continue to strive to simplify the reading level, and have theinformation translated into more languages. In 2003, the program also surveyed hospitalpersonnel involved with patient education and obtaining consent, to obtain their input onreasons for dissent from the supplemental screening panel.

SPECIMEN COLLECTION DATA:
Age at Collection of Initial Specimen
Beginning with the new contract for laboratory testing in July of 2003, the programcontinued to monitor, and more closely scrutinized turn around times given the concernwith sending specimens out of state. To assist with this a new report was generated toassist with identification of specific elements affecting turn around time. By identifyingthe age at which specimens are collected we can identify issues with late collection,batching (holding specimens at the hospital before shipping), or with availability or lackthereof of shipping frequency. The data below reflect generally acceptable compliancewith the regulations that require specimen collection between 24 and 48 hours of life, orprior to discharge, transfer or transfusion whichever occurs first.

Specimens collected at greater than 2 days of age are of greatest concern. Since some of the disorders screened can affect the baby in the first weekof life, the longer specimens wait, the less likely results can be obtained priorto a metabolic crisis. In addition tandem mass spectrometry testingalgorithms are partly based on expected age at collection and the test isconsiderably more reliable for some disorders, when specimens are collected inthe first few days of life.
When specimens are first collected at 7 days or older, the risk of lateidentification of affected newborns, and the risk of the test not identifyingsome of the disorders increases.

Unsatisfactory Specimens for 2002 and 2003
The reason it is important to collect the specimen properly the first time is to avoid anyunnecessary delays that could prevent diagnosis and treatment from happening at theearliest opportunity. For every “unsatisfactory” specimen, a second specimen must becollected which usually requires contacting the parents, having them return with the babyto the hospital, the baby undergoing another heel stick procedure, and of coursetransporting another specimen, conducting the testing and reporting the results. Thisentire repeated process can take several days, and could be very costly to the affectedinfant.
Correct specimen collection is done through direct spotting of the filter paper from theheel stick. Each circle should be completely filled with a single flow of blood andsaturate the filter paper so it is seen completely from the other side. Nothing, includingthe baby’s heel should touch the filter paper where the blood spot is filled. Capillary tubecollection and then blotting the filter paper is not recommended because of problems withscratching the filter paper. The specimen must be allowed to dry for a minimum of threeto four hours, and should always be placed horizontally while drying. (Drying racks areavailable to allow this, while avoiding anything touching the specimen.)
Nebraska hospitals continued to do a generally good job in collecting specimens correctlythe first time. Problems with incomplete or inaccurate data recording on the form,however became much more apparent after the NNSP contracted with Pediatrix. We donot believe this is a new phenomena however. This may merely be a reflection of theincrease in communication between the testing lab and NNSP on quality assuranceissues, by virtue of having a contractual arrangement with the lab.
When it comes to rapid identification andretrieval of affected newborns, complete andlegible demographic information recorded on thefilter paper collection card is just as importantas applying good quality blood spots to the filterpaper!

Drawn Early Specimens For 2002 and 2003
Per regulation, if a baby is to be transferred, discharged or transfused, even if prior to 24hours of age, a specimen is to be collected. When the infant is less than 24 hours of ageat specimen collection time, a repeat specimen is required to screen for PKU, congenitalprimary hypothyroidism and MCAD. (The early drawn specimen will be acceptable forbiotinidase, galactosemia, and hemoglobinopathy screening tests. MCAD results onspecimens collected at less than 12 hours of age also get repeated when the PKU/CPHrepeat specimen is received.)

Transfers Without a Specimen Collected Prior toTransfer for Years 2002 and 2003
The NNSP follow-up coordinator, Krystal Baumert tracks and monitors records toattempt to ensure every baby born in Nebraska benefits from newborn screening. Overthe last several years she has identified a number of instances where newborns weretransferred between hospitals (sometimes involving as many as three hospitals), and noone obtained the screen. Because the data relied upon by the NNSP is triggered by thelaboratory receipt of a specimen, these “missed” babies can only be detected by doing amonthly match with the electronic birth certificate data. Therefore, it is far moredesirable to obtain a specimen prior to transfer (even if the newborn is less than 24 hoursold), than to risk a baby not getting screened until he/she are a month old or older.
Nebraska regulations require specimen collection prior to transfer. They requirethat a transfer form identifying the screening status be completed, sent with thebaby to the receiving hospital, and a copy sent to the newborn screening program. The program received notification of 310 transfers in 2002 and 258 transfers in 2003. However, forms were not always completed to indicate whether or not the specimen hadbeen collected prior to transfer. Doing so would facilitate earlier recognition of the needfor screening on babies who do not get screened prior to transfer. The NNSP recognizesthere are situations in which the attending physician will determine the newborn’scondition to be too medically fragile to collect a specimen prior to transfer, particularlyunder emergency, life-flight circumstances. That is why completing the transfer formand forwarding it to both places (receiving hospital and NNSP) is critical to ensuringappropriate screening is completed.
Nebraska Newborn Screening Program 2002/2003 Report
Specimen Turnaround Time
Because early identification, diagnosis and treatment is so critical to a successfulnewborn screening program, one of the important measures of quality is that of specimenturnaround time. Beginning with the 2nd quarter of 2001, the NNSP began generating theturn around time data for evaluation. (Previously mean averages, minimum andmaximum turn-around-times were reported by the laboratories.) The program’s dataincluded turn around time for test result availability for galactosemia (as recommendedby the Technical Advisory Committee) since this disorder presents the most critical senseof urgency in treatment. Data was broken down by hospital to get mean averages,minimums and maximums. For those results that were available at 10 days of age orolder, a closer look found most often delays were in hospitals holding specimens(batching) or lengthy transportation. Occasionally delays were due to in-hospital latecollection, and rarely, in-lab delays occurred.

One of the biggest concerns with contracting with a laboratoryfor the newborn screening testing, was the potential for testingto go out-of-state. There was concern that turnaround timecould be adversely affected with long transport-times. Thisinitially turned out to be true. However, the Program andAdvisory Committee continue to work closely with the laboratoryand hospitals have seen continuous improvement in this area.

use of the potential for the competitively bid contract to be awarded to an out-of-laboratory, the State Program included a requirement that the bidding laboratories include overnight shipment of the specimens as part of their pricing. The laboratory
as ultimately awarded the contract, Pediatrix Screening Laboratory, met thisrement by their independent contract with United Parcel Service (UPS) thatdes this service from Nebraska’s hospitals.
g the first months of screening with Pediatrix, the program worked with theatory to expand the five-day-a-week overnight service to weekends. Pediatrixssfully negotiated with UPS for Saturday pick-up from the largest birthing hospitals state (in Omaha and Lincoln) accounting for nearly two-thirds of the births. All ofincoln, and all but one Omaha hospital have established procedures for Saturdayup of specimens. This has helped turnaround time, in reducing transport time, asas helping to balance out the day-to-day workload at the laboratory by obtaining specimens on Mondays.
around times the first few months on average were considerably longer thanted. Steady improvement in the average turnaround time has been demonstratede laboratory and program continue to evaluate and look for ways to improve.

For specimen results released, and then re-released with updated information,(such as when the hospital later reports different collection dates or times to correct drawn early status), thesecond “release” date or final report date is the age identified in this data report.
When comparing turnaround times, it is important to recognize the “report” date in themulti-lab system was when the data was entered into the laboratory’s data system, andnot all submitters had electronic access to those results in 2002. With Pediatrixscreening, once the data is released in the data system, every submitter (hospital) can getthose results electronically.
Screening at Pediatrix involved additional second tier testing as part of the initial screen. While this has the intended effect of fewer false positives, and better initial information,the trade-off can be increase in overall turnaround time.
Nebraska Newborn Screening Program 2002/2003 Report

(Presumptive) Positive Screening Rates
Another interesting data set used to help manage newborn screening systems is the rate ofpresumptive positive screening results created by the screening. In determiningappropriate technology, test methods, and test cut-offs for each disease screened, theprimary consideration is how well do these parameters detect every newborn with thedisease. Therefore, it is important to set the cut-off high enough (or low enoughdepending on the test), to be reasonably sure every baby will be detected.
On the other hand, it is a significant concern when the number of false positives areperceived to be too high. A second goal of the program is to keep the number of falsepositives as low as possible while maintaining adequate assurance that affected newbornswill be detected.
There are a number of problems with excessive false positive results. The primary concern is the effect of anxiety and worry on the parent of the child with
the result, and the impact this can have on early bonding between the newborn andparents. Secondly, studies have shown that the effect of this anxiety and worry canbe long lasting, despite concerted efforts to reassure the parents.
An excessive number of false positive results can also lead to a false sense of securitythat the result is “just another false positive,” not meriting assertive action on the partof the newborn’s physician to contact the parents and obtain the confirmatoryspecimen from the newborn. This has the potential to delay the rapid and appropriateaction needed to confirm, diagnose and treat affected infants.
And finally, excessive false positives can be a strain on resources from the hospital,laboratory, physician and the follow-up program.
A third factor has entered the equation of determining cut-offs since screening withPediatrix Screening Laboratory began. In an attempt to reduce false positives, but assuremildly affected newborns who could benefit from treatment are also identified, secondtier testing of DNA panels is done following some positive screening results forbiotinidase deficiency, galactosemia, MCAD and hemoglobinopathies. An unintendedconsequence has been an increase in the request for repeat or confirmatory tests due tothis protocol. While this can help the practitioner with diagnosis, it can also “muddy thewaters” due to the unknown mutations that may contribute to the phenotype, but whichare not part of the second tier screen.
CAVEAT:States use varying instruments, methodologies and cut-offs. In addition, the national datareport notes inconsistencies in reporting by some states which brings into question thevalidity of data. Therefore, direct correlations can not be made from the data that isavailable. However, from the summary of data on the next page one can extrapolate thatin general, Nebraska’s chosen technology, methodologies and cut-offs have resulted inpositive screening rates that are reasonable compared to other newborn screeningprograms across the country. Rates for hemoglobinopathies were not figured due tovariances in reporting methods for the national report, and from states. The national data

LABORATORY TESTING DATA
Since more than one lab performed testing for Nebraska’s newborns in 2002 and part of2003, the program and committee utilized monitoring procedures to achieve anacceptable level of consistency in procedures between labs. We’ve continued thismonitoring with the contracted laboratory to ensure continued quality.
Quarterly lab data: One measure the committee monitors is the mean average values ofinitial screening test results. For comparison purposes the following data shows the datafor the first quarter of 2002 from UNMC and Quest laboratories, and the first twoquarters of screening done in 2003 with Pediatrix Laboratories:
The mean average TSH’s found during the first two quarters of screening with Pediatrixlaboratories in the second half of 2003 were consistent with what would be expectedgiven the previous mean averages obtained from the two labs screening prior to July of03.
------------------------------------------------------------------------------------------------------------
The mean average T4’s have been slightly below that experienced by the prior newbornscreening laboratories. This may be partially explained by the instrument to instrumentvariability, but will continue to be monitored.

The laboratory has continued to collaborate closelywith the program in establishing cut-offs, reporting protocols, and recommendations. ThePediatric Metabolic Specialists are closely involved with establishing therecommendations. Early in July 2003, the program recognized serious problems withexcessive positive biotinidase screening results. Through collaboration the reportingprotocols were changed. Rather than unnecessarily alarming parents and physicians ofthe need for confirmatory testing for a positive screening result, the laboratory was ableto implement a procedure for recommending repeat testing for potentially heat denaturedspecimens. The laboratory continues to refine its ability to screen for

When Pediatrix began screening Nebraska’s newborns in 2003, we also had quantitativevalues for the first time for Galactosemia screening. Not only did we begin receivinginformation about the total Galactose, but the screening result provided a measure ofGALT (Galactose-1-phosphate -uridyl-transferase), the enzyme responsible for mostforms of galactosemia. (The screening program does not claim to be able to detect allkinds of galactosemia – such as the rarer forms due to deficiency of epimerase or kinase.) While this information can be extremely beneficial in helping to diagnose the newborn,it can also complicate follow-up, as more newborns who are carriers or identified withduarte mixed heterozygote genotypes or other variants, may be identified on screening aswe search for the affected newborns. In addition for those newborns with positive results from the total galactose and GALT, second-tier testing of DNA is also done andavailable to the newborn's physician to help with diagnosis.
Similarly to screening for biotinidase deficiency, the enzyme values on average are lowerduring the summer months. This will be monitored by the Program and Committee overthe next year or two as well.

Of the 99 home births reported to the NNSP for 2002, (April 15, 2003 cut-off) themedian age at date of notification of the NNSP was 4 days with the range in age at timeof notification being 1 day to 14 months of age.
Of the 70 home births reported to the NNSP for 2003, (April 15, 2004 cut-off) themedian age at date of notification of the NNSP was 6 days with the range in age at timeof notification being 1 day to 12 months of age.
Ten years of data is included in this annual report in the following sections. Some data isapproximate. The program cannot be certain it knows of every Nebraska birth, as somebirths (e.g. home births) do not become known to the Health and Human Services Systemuntil the birth is registered and occasionally this is past the April 15, annual data cut-offdate.
In 2002, there were 25,515 births reported to the NNSP in Nebraska. In 2003, there were 26,067 births reported to the NNSP in Nebraska.

Supplemental (Tandem Mass Spectrometry ScreeningResults)
Beginning with Pediatrix screening July 1, 2003, the Nebraska Newborn ScreeningProgram acquired the ability to track newborns supplemental screens, and to facilitateconnecting the baby’s doctor with an appropriate specialist with abnormal results werereported. Prior to that time, although some newborns received supplemental screening,only the MCAD results were reported to the program. The data below demonstrates thefirst six months experience with MS/MS screening. In addition to this experience, theprogram has gained considerably from the world class expertise Pediatrix Screeninglaboratory has to offer, as well as from their screening and reporting protocols. Theprogram staff continue to increase our understanding of the screening results. Thisimproves our communication to the newborns’ physicians of an appropriate level ofurgency for repeat or confirmatory testing and consultation with Nebraska’s Pediatricspecialists in metabolism.

Intervention Data
The intervention data is one of the most important measures for determining how well weare doing as a system to ensure timely treatment of affected infants. The following datais grouped by disorder and shows Nebraska’s averages/ranges for 2002 and 2003.
The data also includes national averages/ranges according to the most recent availabledata “National Newborn Screening Report -2000" available at the National NewbornScreening and Genetics Resource Center’s web site:
http://genes-r-us.uthscsa.edu/resources/newborn/00chapters.html
It is interesting to look at how Nebraska compares to the rest of the country on thismeasure. States and territories included in the averages in this report, have birth numbersfrom fewer than 2,000 per year to around 500,000 per year. Likewise, resourcesnecessary to complete testing, follow-up, confirmation, diagnosis and treatment also varyfrom state to state. The intervention data is one kind of outcome data that can, over time,help to identify how well a state’s system is working in newborn screening. The meanaverage age at time of treatment can be an indicator of whether adequate resources aredevoted to each of the components of a comprehensive newborn screening system:education, specimen collection handling and transportation procedures, laboratoryprocedures, follow-up and referral procedures, confirmation and treatment.
Reviews of the following data must take into consideration that exact comparisons cannot be made from the data available.

PLANS
Screening Panel Expansion: Nebraska now screens nearly 100% ofnewborns for six disorders and about 95% of newborns for an additional 26 organic acid,fatty acid and amino acid disorders that can be detected on tandem mass spectrometryscreening. (Counting sub-classes of disorders this number approaches near fiftydisorders). In many states there are a number of disorders on the horizon that have eitherbeen added, or are being evaluated for their appropriateness for addition to requiredscreening panels. Some of these are: Congenital Adrenal Hyperplasia, Cystic Fibrosis,Diabetes Type I, and disorders of immunodeficiency such as Severe Combined ImmuneDeficiency (SCID). Nebraska awaits the ranking of disorders from an American Collegeof Medical Genetics project funded by the Maternal and Child Health Bureau. In themeantime, the Advisory Committee has already begun to evaluate some of the abovedisorders to determine if a recommendation to the Department will be in order. TheProgram and Committee will consider what resources are needed to effectivelyimplement screening for any additional disorder.
State Genetic Planning: The program will continue to look for ways toimplement the recommendations from the State Newborn Screening and Genetics Plan.
CONTINUING ACTIVITIES
Education: Educational activities from the NNSP will continue throughpublication of the Annual Report, and as needed through hospital and physicianmailings. Opportunities for on-site education are always available upon request fromhospitals. Recommendations for improving the Newborn Screening patient educationmaterials will be sought.
Laboratory Testing: The contract with Pediatrix Screening laboratory is aone year contract, renewable for five years. Annual renewals are dependent on theDepartment’s assessment of contractor's performance.
Follow-up/Tracking and Referral: Procedures used by the NNSP totrack every newborn to be sure they received an appropriate screen, to follow-up on alltransferred, drawn early, unsatisfactory, and presumptive positive specimens, facilitateconfirmatory testing and referral for diagnostic and treatment services will continue. Theduties of the Program’s Administrative Assistant have changed to include moreassistance to the follow-up coordinator since the expansion of NBS into the tandem massspectrometry arena.
Nebraska Newborn Screening Program 2002/2003 Report
45
Confirmatory Testing: The program will continue to work with specialistsand the Newborn Screening Advisory Committee to ensure procedures recommended forconfirmatory testing are communicated effectively to practitioners. As the screeningpanel expands, new information will be developed and shared to facilitate practitioner’sunderstanding of “next steps” when a newborn requires further testing to determine themetabolic condition.
Diagnosis: Practitioner’s are strongly urged to consult with the pediatric specialistappropriate to the disorder for which a newborn has a positive screening result. Theprogram will help the newborn’s primary care provider know who is available to contactin these circumstances.
Treatment: Access to treatment was an issue the program had requested theNewborn Screening and Genetics Planning Grant Advisory Committee to review. Funding sources exist for pharmaceutically manufactured foods and formulas for patientswith PKU. However, there are some known gaps, e.g. funding for sickle cell and sicklecell trait genetic services, payment sources for routine blood phenylalanine levels forchildren and women of childbearing age. There are other areas for which we don’t knowthe issues with accessing treatment, e.g. affordability/insurance coverage of levothyroxinfor patients with congenital primary hypothyroidism. The Program will continue tomonitor the issues associated with access to treatment.
Quality Assurance Monitoring: The Program and Advisory Committeewill continue to review and act on quarterly quality assurance plan data as well asrespond to trends identified with any problems in the interim periods.

SECTION IINEWBORN HEARING SCREENING
WHY IS THIS REPORT IMPORTANT?
Significant hearing loss is the most common birth defect with an estimated incidence rateof one to three per thousand live births. Left undetected, hearing loss in infants cannegatively impact speech and language acquisition, academic achievement, and socialand emotional development. Before newborn hearing screening, many hearing losseswere not diagnosed until 2 ½ to 3 years of age. If detected early, however, the negativeimpacts can be diminished, and even eliminated, through early intervention. Recentstudies have consistently shown that children who were identified with a hearing losslater in childhood have delays in the development of speech, language, social andacademic skills compared with those identified during the first six months of age.
Newborn hearing screening is an essential preventative public health program. It meetsthe following prerequisites for a population screening program –
• Condition is sufficiently frequent in the screened population• Condition is serious or fatal without intervention• Condition must be treatable or preventable• Effective follow-up program is possible
In 2000, the Infant Hearing Act established newborn hearing screening in Nebraska. Thestatute requires hospitals to educate parents about newborn hearing screening,encouraged hospitals to voluntarily begin screening newborns for hearing loss, and, byDecember, 2003, to include hearing screening as part of its standard of care and toestablish a mechanism for compliance review. The Act also requires that regulations bepromulgated to mandate newborn hearing screening if, by December 2003, less than 95%of newborns in the state were receiving a hearing screening. This report presents thestatus of newborn hearing screening in Nebraska during 2002 and 2003 (see Part III,Nebraska Newborn Hearing Screening Data for 2002-2003).
WHAT IS NEWBORN HEARING SCREENING?
Newborn hearing screening requires objective physiologic measures to detect hearingloss in newborns and young infants. There are two basic measures that birthing hospitalsin Nebraska use to screen newborns for hearing loss. Both are easily recorded innewborns and are noninvasive measures of physiologic activity that underlie normalauditory functioning.
The most frequently used screening technique is measurement of otoacoustic emissions,or OAEs. A miniature earphone and microphone are placed in the newborn’s ear canal,low intensity sounds are presented, and responses produced by the inner ear aremeasured. The second screening technique, Auditory Brainstem Response, or ABR, uses
Nebraska Newborn Screening Program 2002/2003 Report
47
band aid-like electrodes to detect certain brainwaves in response to sounds that arepresented by a miniature earphone. For both methods, the response of each ear ismeasured. OAE and ABR are both reliable and accurate. Screening can occur as early as12 hours of age, preferably with the newborn sleeping, and averages from five to 20minutes to complete.
If a response is not detected for one or both ears, the result is a “refer” (did not pass). A“refer” to the screening test indicates that a hearing loss may exist but there are also otherfactors that may have contributed. A “refer” does indicate that a second screening isnecessary to determine if the other factors, such as vernix in the ear canal, fluid in themiddle ear cavity, movement, equipment failures, or inexperience of the tester,contributed to the initial result. A “refer” on the second screening usually indicates theneed for a diagnostic audiological evaluation to confirm or rule out a hearing loss and, ifhearing loss is present, to begin to identify the type and degree of the loss.
Each birthing hospital has established a newborn hearing screening protocol thatidentifies how the screening will be administered, the recording and reportingprocedures, how refers will be handled, i.e., re-screen as an inpatient with the same ordifferent screening technique or re-screen as an outpatient, and quality assurancemeasures.

Part I
THE NEWBORN HEARING SCREENING SYSTEM
System Elements
The newborn hearing screening system in Nebraska is composed of five functionalelements working together to fulfill the purposes of the Infant Hearing Act (Neb. Rev.Stat. §71-4735):
• “To provide early detection of hearing loss in newborns at the birthingfacility, or as soon after birth as possible for those children born outside of abirthing facility,
• To enable these children and their families and other caregivers to obtainneeded multidisciplinary evaluation, treatment, and intervention services atthe earliest opportunity and
• To prevent or mitigate the developmental delays and academic failuresassociated with late detection of hearing loss; and
• To provide the state with the information necessary to effectively plan,establish, and evaluate a comprehensive system for the identification ofnewborns and infants who have a hearing loss.”
The five functional elements of the newborn hearing screening system are: HearingScreening at Birth, Confirmatory Testing, Medical Evaluation, Early Intervention, andTracking and Surveillance. One or more groups of professionals in a variety of settingsassume responsibility of each element of the system. An overview of each of theelements and the primary activities are presented below. Included in this discussion arethe Nebraska Revised Statute citations and the recommended protocols established by theDepartment of Health and Human Services through the Nebraska Newborn HearingScreening Advisory Committee.
Hearing Screening at Birth
Birthing hospitals in Nebraska have five primary activities related to screening thehearing of newborns:
1. The parent(s)of newborns are educated about the hearing screening, the likelihoodof hearing loss in newborns, the importance of follow-up, community resources(including early intervention services), and normal auditory, speech and languagedevelopment (Neb. Rev. Stat. §71-4740, Recommended Protocols). If risk factorsare present, hospital staff educate parents to evaluate hearing every six months. Note: The Department of Health and Human Services is responsible for educatingthe parent(s) for newborns not born in a birthing facility (Neb. Rev. Stat. §71-4740, Recommended Protocols).
2. A hearing screening test is part of each birthing hospital’s standard of care fornewborn, effective 12/1/03 (Neb. Rev. Stat. §71-4742). Following hospital
Nebraska Newborn Screening Program 2002/2003 Report
49
protocol for the procedure, each newborn’s hearing in both ears is screenedduring birth admission using OAE and/or ABR screening techniques. A secondinpatient screening is conducted within one to three weeks if the baby “refers” onthe first screening (Recommended Protocols). The outpatient re-screening forthose that “refer” during birth admission, may occur at the birthing facility or at aconfirmatory testing facility.
3. A mechanism for compliance review is established for each birthing facility (Neb. Rev. Stat. §71-4742).
4. Results of the hearing screening for each newborn are reported to the newborn’sPrimary Care Provider. Weekly tracking reports are submitted to the NNHSP thatidentify newborns who “refer,” transfer, or discharge without a hearing screening. (Recommended Protocols).
5. Annual reports are submitted to the NNHSP that indicate the following numbers:born in the birthing facility, recommended for screening, received screeningduring birth admission, passed screening, did not pass screening, andrecommended for monitoring and follow-up (Neb. Rev. Stat. §71-4739).
Confirmatory Testing
Newborns who have referred for one or both ears on the second hearing screening shouldreceive an audiological diagnostic evaluation prior to reaching three months of age. Thepurpose of this evaluation is to confirm the presence of a hearing loss and to determinethe type and degree of the hearing loss. The primary activities that comprise theconfirmatory testing component are:
1. An initial diagnostic evaluation using either OAE or ABR conducted as early aspossible after referral, preferably before the infant is six weeks old. If the infant“passes” this initial part of the evaluation (outpatient re-screening), no furtherevaluation is usually needed (Recommended Protocols).
2. If the infant “refers” on the initial part of the evaluation, the testing oftenproceeds immediately to a comprehensive diagnostic evaluation. This evaluationminimally includes measures of middle ear function (tympanometry), auditorysensitivity (air- and bone-conducted ABR), confirmatory measures (parentobservations), and, depending upon the developmental age, behavioralaudiological assessment (Visual Reinforcement Audiometry). Other measuresmay be included, as indicated (Recommended Protocols).
3. Depending upon a variety of factors, referrals are made for further evaluation,diagnosis, treatment, and services. These referrals may be made to medicalspecialists and/or Early Intervention Services (Recommended Protocols).
4. Results of the initial and comprehensive audiological diagnostic evaluation areprovided to the Primary Care Physician and NNHSP (Recommended Protocols).
5. Annual reports are submitted to the NNHSP that indicate the number ofnewborns: who return for follow-up testing, who do not have a hearing loss andwho do have a hearing loss (Neb. Rev. Stat. §71-4739).
Nebraska Health and Human Services System
50
Medical Evaluation
The infant’s Primary Care Provider (PCP) has the key role in the follow-up for those who“refer” on the initial hearing screening during the birth admission. Building on theconcept of a pediatric medical home (Guidelines for Pediatric Medical Home Providers,AAP), the PCP has the primary role in identifying and accessing all the medical and non-medical services needed to help children and their families achieve their maximumpotential. The primary activities that comprise the medical element of the newbornhearing screening system are:
1. Birthing hospital notifies PCP of the newborn’s hearing screening results(Recommended Protocols).
2. NNHSP notifies PCP about the hearing screening status and need for follow-upevaluation for those that did not pass the inpatient hearing screening or weredischarged without a screening (Recommended Protocols).
3. PCP or designee per hospital procedure informs parents of hearing screeningresults and need for re-screening (Recommended Protocols).
4. PCP (or staff), hospital, or test provider schedules re-screen appointment to becompleted in one to three weeks and notifies parents (Recommended Protocols).
5. Provider of outpatient re-screening notifies PCP of results (RecommendedProtocols).
6. PCP notifies NNHSP of outpatient hearing re-screening results (RecommendedProtocols).
7. If “refer,” PCP makes referral for comprehensive diagnostic evaluation, educatesparents about need for evaluation, and makes referral to Early Interventionservices (Recommended Protocols).
8. If hearing loss is confirmed, PCP or diagnostic evaluator refers newborn/infantfor complete medical and/or neuro-sensory evaluation and Early InterventionServices (Recommended Protocols).
Early Intervention
Early Intervention is an individualized program of services and supports based on theneeds of the individual and family. Part C of the Individuals with Disabilities EducationAct (IDEA) authorizes the creation of early intervention programs for infants andtoddlers with disabilities. In Nebraska, the Early Development Network (EDN) providesservice coordination for eligible families to identify and link with needed services, towork with multiple providers to ensure that services are provided, and to becomecoordinators of services in the future. An important aspect of early intervention forinfants with a hearing loss is the selection and fitting of amplification. The recommendedprotocols for the primary Early Intervention activities within the newborn hearingscreening system are:
1. PCP or diagnostic evaluator makes referral to Early Development Network (EDN).2. EDN reviews for eligibility.3. If eligible, EDN may provide assistance with diagnostic evaluation and treatment.4. Services Coordinator may facilitate obtaining services from otologists, audiologists,
community services, and others.
Nebraska Newborn Screening Program 2002/2003 Report

Tracking and Surveillance
The Nebraska Newborn Hearing Screening Program has been developed based on therequirements identified in the Infant Hearing Act (Neb. Rev. Stat. §71-4735 - §71-4744)and the NNHSP Advisory Committee recommended protocols to “…determine andimplement the most appropriate system…to track newborns and infants identified with ahearing loss” and “…to effectively plan and establish a comprehensive system ofdevelopmentally appropriate services for newborns and infants who have a potentialhearing loss or who have been found to have a hearing loss and shall reduce thelikelihood of associated disabling conditions” (Neb. Rev. Stat. §71-4737). Activities ofthe NNHSP include:
1. Develop, implement, and monitor statewide systems to track newborns with or at-risk of hearing loss (Neb. Rev. Stat. §71-4737) and adopt and promulgate rulesand regulations to implement the Infant Hearing Act (Neb. Rev. Stat. §71-4742and §71-4744).
2. Gather required data and generate annual reports (Neb. Rev. Stat. §71-4739 and§71-4741).
3. Establish guidelines for referral to early intervention services (Neb. Rev. Stat.§71-4743).
4. Educate parents with out-of-hospital births about newborn hearing screening(Neb. Rev. Stat. §71-4740)
5. Apply for all available federal funding to implement the Infant Hearing Act (Neb.Rev. Stat. §71-4738).
System Protocols
Newborn hearing screening is one aspect of a comprehensive, integrated Early HearingDetection and Intervention (EHDI) system. The first three principles of the Year 2000Position Statement: Principles and Guidelines for Early Hearing Detection andIntervention Programs (Joint Committee on Infant Hearing, 2000) are:
1. All infants have access to hearing screening using a physiologic measure. Newborns who receive routine care have access to hearing screening during theirhospital birth admission. Newborns in alternative birthing facilities, includinghome births, have access to and are referred for screening before 1 month of age. All newborns or infants who require neonatal intensive care receive hearingscreening before discharge from the hospital. These components constituteuniversal newborn hearing screening (UNHS).
2. All infants who do not pass the birth admission screen and any subsequentrescreening begin appropriate audiologic and medical evaluations to confirm thepresence of hearing loss before 3 months of age.
3. All infants with confirmed permanent hearing loss receive services before 6months of age in interdisciplinary intervention programs that recognize and buildon strengths, informed choice, traditions, and cultural beliefs of the family.
These three major principles serve as the foundation for the screening, referral, and

audiological evaluation protocols developed by the Nebraska Newborn HearingScreening Advisory Committee in 2001. The timelines established by the NNHSPAdvisory Committee are for hearing screening to be completed by 1 month of age,audiological diagnostic evaluation to begin prior to six weeks of age and completed priorto three months of age, and appropriate early intervention activities to be initiated by sixmonths of age. Highlights of the current protocols include:
Screening Protocol
1. Hospital provides education to parent(s) about hearing screening, likelihood ofhearing loss, follow-up procedures, and normal auditory, speech and languagedevelopment. For out-of-hospital births, the Nebraska Newborn HearingScreening Program (NNHSP) provides this education.
2. Hospital screens newborn using OAE and/or ABR methods following hospitalprotocol. (If newborn “refers,” a second inpatient screening is encouraged)
3. Hospital informs Primary Care Physician of hearing screening results.4. Primary Care Physician informs the newborn’s parent(s) of the hearing screening
results.5. If newborn “refers” on inpatient hearing screening or discharged prior to valid
screening: • Hospital schedules an outpatient re-screen (optional)• Hospital completes and submits tracking form weekly to notify NNHSP of
results• NNHSP sends letter and follow-up reporting form to Primary Care Physician• Outpatient re-screening scheduled by Primary Care Physician and/or parent in
1-3 weeks• Primary Care Physician notifies NNHSP of the re-screening results• If re-screening results are not received within two weeks of initial letter,
NNHSP sends a second request to Primary Care Physician and sends a letterto the newborn’s parent(s) encouraging a re-screening.
5. If newborn is transferred prior to screening:• Birth hospital notifies receiving hospital (NICU) that screening not completed• Birth hospital notifies NNHSP of transfer on weekly tracking form• NNHSP sends follow-up form to receiving hospital• Receiving hospital screens infant using OAE and/or ABR methods following
hospital protocol. (If newborn “refers,” a second inpatient screening is encouraged)• Receiving hospital notifies Primary Care Physician and NNHSP of screening
results6. If parent(s) refuse hearing screening:
• Hospital notifies Primary Care Physician of refusal• Hospital documents refusal
Referral Protocol
1. For the infants who have referred on a second hearing screening, the PrimaryCare Physician will make a referral for an audiological diagnostic evaluation.
Nebraska Newborn Screening Program 2002/2003 Report
53
2. The Primary Care Physician will also make a referral to Early InterventionServices (Early Development Network) to determine eligibility and possibleassistance.
3. If a hearing loss is identified from the audiological diagnositc evaluation, referralsneed to be made for a comprehensive medical and/or neuro-sensory geneticsevaluation to identify the etiology of the hearing loss. Appropriate treatment andintervention approaches will be implemented based on all of the evaluations. There are many causes for hearing loss in newborns and infants, ranging frommiddle ear dysfunction to viral infections during pregnancy to genetic deafness. About half of congenital deafness is hereditary (Northern and Downs, 1991). Genetic deafness may be syndromic, in which there are other medical problems inaddition to the hearing loss, or nonsyndromic, where hearing loss is the onlyobvious medical condition.
Audiological Diagnostic Evaluation Protocol
1. The initial diagnostic measure of peripheral auditory status is a form of outpatientscreening and should be completed prior to six weeks of age to minimize the needto sedate the infant. The majority of infants should pass at this stage and nofurther testing will be needed. One of the following procedures will be used atthis stage:• Transient Evoked Otoacoustic Emissions (TEOAEs): half-octave bands
centered at 1.5, 2, 3, and 4 kHz in response to a click• Distortion Product Otoacoustic Emissions (DPOAEs): f2 frequencies from 2 to
6 kHz in half-octave steps for primary levels of 65/55 dB SPL for L1/L2.• Click-evoked Auditory Brainstem Response (ABRs) at 30 dB HL
2. If an infant does not pass the initial diagnostic procedure, comprehensivediagnostic procedures should be initiated immediately. These procedures mayoccur over a series of evaluation sessions to obtain a complete description of theinfant’s auditory capabilities. Measures of Middle Ear Function• Tympanometry with a 226 Hz probe tone (higher frequency probe tone
recommended) for an objective measurement of the tympanic (eardrum)membrane mobility and middle ear pressure.
• Acoustic reflex (middle ear muscle reflex) measured with 1 and 2 kHzeliciting stimuli, as indicated by other clinical measures.
Measures of Auditory Sensitivity• ABR measurements using click stimuli to obtain information about thresholds
and configuration of the hearing loss. • ABR measurements using tone-burst stimuli for low (250 or 500 Hz), middle
(1 or 2 kHz) and high (4 kHz) frequencies provide information about hearingsensitivity as a function of frequency. The frequency-specific measures mayalso be used for the selection of appropriate amplification.
• Bone-conducted ABR measurements using clicks and/or tone bursts provideinformation about the magnitude of a suspected conductive hearing loss for
Nebraska Health and Human Services System
infants with middle ear dysfunction. • Steady-State Evoked Responses (SSEP) or Auditory Steady State Response
(ASSR) is currently gaining acceptance for inclusion in the diagnostic testbattery. An advantage of ASSR includes obtaining frequency-specificestimates of threshold with severe-to-profound hearing loss.
Confirmatory Measures• TEOAEs and DPOAEs measures, as part of the diagnostic test battery, may
serve to confirm the degree and configuration of hearing loss determined withABRs.
• Parent/Primary Caregiver Observations are an important check to assure thatauditory sensitivity is being estimated appropriately.
Behavioral Audiological Assessment (six months developmental age and older)• Visual Reinforcement Audiometry (VRA) yields reliable behavioral threshold
information. After the child is conditioned to associate sound with a visualreinforcer, head turns toward the reinforcer in response to an auditorystimulus is a reliable response. The use of insert earphones in the ear canalcan yield ear-specific thresholds.
Amplification Assessment Protocol

etc., and Technical Considerations, such as type of microphone (directional oromnidirectional), circuitry (digital, programmable, or analog), and FMcompatibility, must be considered in the hearing aid selection process.
Special Circumstances
1. Late Onset or Acquired Hearing Loss associated with risk factors such asprogressive hereditary hearing loss, cytomegalovirus (CMV), craniofacialanomolies, meningitis, etc., may not be detected by hearing screening conductedprior to hospital discharge. Screening and/or evaluation of auditory function canand should be accomplished at any time when risk factors are present or whenparent(s)/caregiver(s) express concern about the child’s responsiveness to sound.
2. Auditory Neuropathy is a condition in which the peripheral (sensory) portion ofthe auditory system is functioning normally but the central (neural) portion of thesystem is not. Diagnosis is made when OAEs are present but ABRs are eithergrossly abnormal or absent. Currently it is a matter of debate about which ofseveral habilitative options is most appropriate.

MAJOR INITIATIVES FOR 2002 AND 2003
Federal MCHB Grant for System Integration andEducation
Neb. Rev. Stat. §71-4738 requires that the Nebraska Newborn Hearing ScreeningProgram (NNHSP) apply for all available federal funds. NNHSP has applied for andreceived Universal Newborn Hearing Screening (UNHS) grant funding from the federalMaternal and Child Health Bureau (MCHB). NNHSP received $55,000 in 2002 and$45,000 in 2003. The grant funds were used for:
• Development of a computer-based surveillance and tracking system to be used byall hospitals conducting newborn hearing screening and the NNHSP to facilitatefollow-up. An electronic data system would contribute greatly to the ability touse data for quality assurance analysis and to increase the accuracy of informationfor follow-up purposes. A Request-for-Proposal (RFP) was developed and, aftervendor demonstrations, the NNHSP Advisory Committee and EvaluationCommittee recommended not purchasing an existing tracking and surveillancesystem because of cost. Development of an integrated web-based system tofacilitate entering the data at the hospital was begun with HHSS InformationServices and Technologies, Newborn Screening and Genetics Program, BirthCertificate Registry and Birth Defects Registry program staff. Work on thatproject was discontinued when an RFP was issued for a web-based vital statisticssystem to comply with CDC requirements. Hearing screening was included as anoptional module in the RFP.
• Increased professional education and public awareness of the importance ofnewborn hearing screening. During 2002 and 2003, MCHB funds were used to: • develop and disseminate parent informational brochures to hospitals• revise and disseminate the NNHSP Resource Directory• conduct annual educational needs assessments of hospital staff• conduct training and technical assistance site visits to 11 hospitals• purchase and disseminate parent education videotapes in English and Spanish
to hospitals• develop and disseminate semi-annual newsletters• conduct a series of parent focus groups• conduct a one day conference “Baby…Can You Hear Me?” for 141
participants on November 1, 2002, and • support the registration of eight audiologists to participate in a pediatric
audiology workshop “Auditory Evaluation for Infants Referred from NewbornHearing Screening.”

Care Cash Fund from which a sub-grant process was developed. The sub-grants were toprovide $2,000 to birthing hospitals with fewer than 500 births per year to assist with thepurchase of newborn hearing screening equipment and program development during2002 and 2003. Sub-grants of $2,000 each were awarded to 24 hospitals in 2002 and to14 hospitals in 2003. The birthing hospitals that were awarded sub-grant funds had atotal of 2,186 births in 2003, an average of 58 births per hospital. The 38 hospitals are:

The funds remaining from the Nebraska Health Care Cash Fund grant have been approved andcommitted for purchase of the optional newborn hearing screening module with the State’s web-based vital records system.
Education
Neb. Rev. Stat. §71-4740 requires that parents be educated on the importance of a hearingscreening test and necessary follow-up, including information about the hearing screening, thelikelihood of a hearing loss in newborns, follow-up procedures, community resources, andnormal auditory, speech and language development. The NNHSP has developed a parenteducation brochure that is provided free-of-charge to all birthing hospitals. The brochure,available in English and Spanish, provides statewide consistency in the quality of informationbeing provided to parents. In addition, the English, Spanish, and closed-captioned versions ofthe videotape “A Parent’s Guide to Newborn Hearing Screening” was provided free-of-charge toall birthing hospitals to support their parent education efforts.
Neb. Rev. Stat. §71-4740 also requires that if a newborn is not born in a birthing facility, theDepartment of Health and Human Services must educate the parent(s) about receiving a hearingscreening and necessary follow-up, as well as information to assist the parent(s) in having thetest performed within three months after the birth. Birth information is received from theNebraska Newborn Screening Program or the Electronic Birth Certificate Registry afterinformation is submitted to file for the birth certificate on infants not born in a birthing facility. The NNHSP sends a letter to the parent(s) along with educational brochures and a listing of thehospitals and audiologists that can provide hearing screening. The letter includes a form for thehearing screening test provider to complete and return to NNHSP with the screening results. In2002, 14% of the 80 out-of-hospital births completed the hearing screening, and in 2003, 15% ofthe 68 out-of-hospital births completed the screening.
Hospitals are surveyed as part of the annual report to determine the training needs of the hearingscreening staff. This information is used to determine the content of newsletter articles andtraining to be provided during site visits. The training areas identified by more than 20% of thehospitals in 2003 are:
• Equipment use and how to decrease “refer” rates• How to implement an in-hospital quality assurance program for newborn hearing
screening• Educating parents about hearing screening• Communicating results to parents• Educating parents about acquired or late-onset hearing loss• How to get families to return for testing when their newborn “refers” or has an
incomplete screen
Eight audiologists from across the state participated in a three-part workshop “Auditory
Nebraska Newborn Screening Program 2002/2003 ReportEvaluation of Infants Referred from Newborn Hearing Screening.” The National Center forHearing Assessment and Management (NCHAM) at Utah State University sponsored theworkshop that included the following topics: anatomy and physiology of the infant auditorysystem, electrophysiological results in pediatric clients, otoacoustic emissions – pediatric results,ABR – click measures, frequency-specific measures, bone conduction measures, use of sedation,timely appropriate diagnosis, and referral for early intervention. The workshop consisted of sixweekly chatrooms based on required readings, an on-line exam, a two-day on-site workshop, anda practicum experience. Continuing education credits were available for the workshop.
The conference “Baby…Can You Hear Me?” was attended by 141 physicians, hospitalpersonnel, audiologists, early intervention providers, Educational Service Unit personnel, andparents on November 1, 2002 in Kearney. The keynote speakers were Karl White, Ph.D. fromNCHAM and Mary Pat Moeller, Ph.D. from the Boys Town National Research Hospital. Trainers for the eight workshop sessions included a geneticist, a pediatrician, an otologist, fouraudiologists, two early interventionists, and a registered nurse. The conference was fundedthrough federal MCHB funds at minimal cost to the participants. Continuing education creditswere available for nurses and audiologists. Conference evaluations were very positive andindicated that the conference should be offered annually.
Parent Survey
Semi-annually, a cross-section of 10% of the parents of newborns who “referred” or dischargedwithout a hearing screening are surveyed to evaluate the effectiveness of the newborn hearingscreening system in Nebraska. Highlights from the most recent survey in 2003 indicate that:
• Written educational materials are very understandable, attractive, provided at the righttime, and contain the right amount of information.
• On a 1-to-5 scale (1=strongly disagree, 5=strongly agree), the average ratings of therespond ts about their experience in obtaining follow-up hearing screening testing were:I receive help to know exactly what to do and where to go 4.4 (strongly agree)My doctoThe testsPaying foI was treThe expeI needed

State staff advisors have represented the Department of Education, Early Intervention Service Coordination, Medically Handicapped Children’s Program and Office of Family Health. Thescope of responsibility for the Advisory Committee has been to:
• Make recommendations for the most appropriate electronic tracking system and theinterim manual tracking system. Neb. Rev. Stat. §71-4737 mandates that the Department of Health and Human Servicesdetermine and implement the most appropriate system that is available to tracknewborns/infants with hearing loss or at risk for hearing loss. With the guidance of theNNHSP Advisory Committee, an interim manual tracking system was developed andprovided to hospitals with instructions necessary for its completion. The EvaluationCommittee participated in the review of the RFPs for the electronic tracking system andvendor demonstrations. The Evaluation Committee and the Advisory Committeerecommended not to purchase an existing system due to the cost of the systems.
• Make recommendations regarding newborn hearing screening methods and protocolsthat should be utilized. The Advisory Committee worked closely with the NNHSP staff to develop protocols fornewborn hearing screening, referral, audiological diagnostic evaluation, andamplification assessment (protocol highlights on pages 50 - 54). These protocols havenot been modified since they were originally developed.
• Participate with staff in developing consensus on the best practices to promote newbornhearing screening in Nebraska. The primary activity of the Advisory Committee in this area in 2002 and 2003 was inevaluating the applications for the Nebraska Health Care Cash Fund sub-grants topurchase hearing screening equipment and to develop their programs. Thirty-eighthospitals with less than 500 births annually received $2000 sub-grants (see listing onpage 56).

NEWBORN HEARING SCREENING DATA FOR 2002 and 2003
Birthing Facilities Data for 2002 and 2003
Hospital Screening Programs
The number of hospitals conducting newborn hearing screening has increased rapidly since 2000when only 11 hospitals were conducting either targeted or universal newborn hearing screening. By the end of 2003, 100% of the birthing facilities in Nebraska were conducting hearingscreenings, consistent with Neb. Rev. Stat. §71-4742 requirement that a hearing screening test beincluded as part of the standard of care for newborns. Sixty five of the birthing hospitals wereconducting the hearing screening during the birth admission and two were conducting thescreening on an outpatient basis following discharge. Sub-grants of $2000 each were providedthrough the Nebraska Health Care Cash Fund to 38 hospitals with less than 500 births annuallyto purchase hearing screening equipment. In 2002, 24 hospitals received grants and anadditional 14 hospitals were funded in 2003.

Table 1
As discussed previously in this report, there are two measurement techniques used to conductnewborn hearing screening: Otoacoustic Emissions (OAE) and Auditory Brainstem Response(ABR). Half of the birthing hospitals in Nebraska are using OAE-only, almost one third areusing ABR-only, and the remaining birthing hospitals are using a 2-step method (OAE, followedby ABR if the initial screening is a “refer”). As can be seen in Table 2, the “refer” rates differfor the three approaches, with the OAE-only having the highest refer rate. The combined referrate for all of the hospitals is 3.6%.

Newborn Hearing Screening Annual Hospital Reports
Birthing facilities are required to annually report specific information about their newbornhearing screening programs to the Department of Health and Human Services (Neb. Rev. Stat.§71-4739). Reports were received from all birthing facilities for 2002 and 2003.

The data in Table 3 are based on annual aggregate data reported by the birthing hospitals. Screening results and demographic data are not reported for all births. The NNHSP only receivesspecific information about newborns that “refer” on the initial hearing screening and about thosethat were discharged without receiving a hearing screening during the birth admission. A marginof error exists in comparing the aggregate numbers with other existing data such as actual recordcounts. Examples of the extent of the reporting errors in 2003 include:
Nebraska Newborn Screening Program 2002/2003 Report
63
• Number of newborns born: 26,023 reported by hospitals to NNHSP compared with 26,011 births according to vital records (excluding 68 home births) – an over-reporting toNNHSP of 12 births.
• The annual aggregate reports from the hospitals to NNHSP indicated 25,275 newbornswere screened. The same reports indicated 24,430 passed and 909 “refers” for a total of25,339 screenings. This is a difference of 64 screenings.
• Number of newborns who did not pass a hearing screening: 909 reported by the hospitalsto NNHSP compared with a record count (spreadsheet entries, hard copy files) of 842 - adifference of 66 “refers.”
The opportunity for error exists within the current manual tracking system due to reportingerrors, recording errors, duplicated entries because of newborn name changes, transfers frombirth hospitals to NICUs, and whether newborns who expire are included in the weekly and/orannual reports. Without a system to accurately determine the status of each newborn’s hearingscreening results, errors will be present in spite of the best efforts of everyone involved toprovide accurate information.
Parent Education
Recommending a hearing screening test has been operationally defined as educating parentsabout newborn hearing screening, as required by Neb. Rev. Stat. §71-4740. The NNHSPprovides patient education materials free of charge to hospitals to help fulfill this requirement. During 2001 and 2002, the birthing hospitals reported that 92% of parents were educated abouthearing screening. In 2003, as the number of hospitals offering hearing screening increased to100%, the number of hearing screenings recommended through parent education increased to96.7%.
Newborns Receiving a Hearing Screening
The Infant Hearing Act requires that rules and regulations be adopted and promulgated if at least95% of the newborns in Nebraska do not have a hearing screening by December 1, 2003, or atany time thereafter. The annual aggregate reports submitted by the hospitals in 2003 show that96.92% of the 26,079 resident births in the state were screened during birth admission. Theincrease in numbers of newborns screened during birth admission has increased dramaticallysince reporting began in 2000, when only slightly more than one third of newborns received ahearing screening during birth admission (see Chart 1 and Table 4). This increase in thenumbers of newborns receiving a hearing screening corresponds to the increase in the number ofhospitals adopting newborn hearing screening as the standard of care for newborns and thesupport of sub-grants through the Nebraska Health Care Cash Fund to purchase screeningequipment for smaller hospitals.

Newborns Discharged Without a Hearing Screening
During 2003, the annual aggregate hospital reports to NNHSP indicated that there were 804newborns who did not receive a hearing screening. Included in this group are newborns whoexpired prior to screening (55), newborns born at hospitals before hearing screening wasimplemented at the birthing hospital, and some newborns that were transferred to anotherhospital’s NICU. There were 84 newborns reported via weekly reports as discharged prior toreceiving a hearing screening test for the following reasons: invalid results (technical/equipment
problems), could not test (baby too active/restless), discharged before screened, newbornadopted, and parent refusal. Slightly less than half (45%) of those newborns discharged withouta hearing screening received one on an outpatient basis within an average of 23 days after birth. Twenty did not receive a hearing screening as an outpatient. An additional 20 were eitheradopted prior to the hearing screening or the parent(s) refused the screening.
Out-of-Hospital Births
Neb. Rev. Stat. §71-4740 requires the Department of Health and Human Services to educateparents of newborns who are not born in a birthing facility about the importance of newbornhearing screening and to provide information to assist them in having the screening performedwithin three months after the child’s birth. Although parent education was provided to theparents of all reported out-of-hospital births during 2002 and 2003, less than 15% of the out-of-hospital births were screened (see Table 5).

Birth Admission Refer Rates
Of the newborns with hearing screenings conducted during the birth admission, the refer ratewas 3.7% during 2002 and 3.6% during 2003. These overall refer rates compare favorably withnational statistics that indicate an average refer rate of 3.4% for the 36 states with refer rates ofless than 5% during the latter half of 2003 (NCHAM 2004 State EHDI Survey).
Monitoring, Intervention, and Follow-up
The final data reported by the birthing hospitals is the number of newborns recommended formonitoring, intervention, and follow-up care: 709 (85% of refers) in 2002 and 676 (74% ofrefers) in 2003. The reporting of the data for this item seems to be inconsistent withapproximately 75% of the hospitals recommending that newborns with a “refer” status on theinitial hearing screening need additional monitoring, intervention, and follow-up. The remaininghospitals report very few recommendations for monitoring, intervention, and follow-up care. Beyond the lack of a clear operational definition for this item, the reasons for fewerrecommendations than “refers” is unknown.
Newborns Not Screened
Neb. Rev. Stat. §71-4742 states: “…it is the goal of this state to achieve a 100-percent screeningrate.” While Nebraska has made great strides in developing a comprehensive newborn hearingscreening system, there are also infants for whom the status of their hearing at birth has not beenverified. In 2003, there were 804 newborns for whom an initial screening cannot be verified. Ofthose that did not receive an initial screening during birth admission, 151 expired, 58 were out-of-hospital births with no hearing screening completed, 17 refused, and at least 20 weredischarged without a screening and no follow-up occurred. Another 153 that “referred” on thehearing screening during birth admission and/or initial outpatient screening with no furtherfollow-up evaluation verified.
Audiological/Confirmatory Test Provider Data for 2002 and2003
Neb. Rev. Stat. §71-4739 requires confirmatory testing facilities to report the followinginformation:
• Number of newborns and infants who return for a followup hearing test• Number of newborns and infants who do not have a hearing loss based upon the
followup hearing test• Newborns and infants who are shown to have a hearing loss based upon the follow-up
hearing test
The Advisory Committee for the NNHSP, consistent with recommendations of the American Academy of Pediatrics and the National Center for Hearing Assessment and Management
Nebraska Health and Human Services System
66
(Guidelines for Pediatric Medical Home Providers, AAP), identified the initial level of the follow-up hearing test as an outpatient re-screening of the newborn’s hearing. For thosenewborns and infants who pass this initial level of the follow-up hearing test, no furtheraudiological evaluation would be needed, unless there are risk factors present that would warrantperiodic evaluation. The Advisory Committee recommends that the re-screening occur withinthe first six weeks to minimize the need to sedate the infant to obtain reliable results and so thatintervention can begin early if a hearing loss is identified.
Since the majority of newborns will pass this second screening, considerable cost savings canresult by using either the OAE and/or ABR screening technique rather than proceeding directlyto a complete diagnostic audiological evaluation. The Advisory Committee’s AudiologicalDiagnostic Protocol recommends that the referral center should be prepared to providecomprehensive audiological diagnostic procedures if the outpatient re-screening results indicatea “refer” status. However, some communities that do not have audiology services readilyavailable have opted to have the initial re-screening occur at the birthing hospital on anoutpatient basis.
Newborn Hearing Screening Annual Confirmatory Testing Facility Reports
Each year data regarding the follow-up hearing tests at confirmatory testing facilities have beengathered by surveying the audiologists in Nebraska. The results of those surveys for 2002 to2003 are included in Table 6 below.

Rate of Follow-up Re-screening/Testing
As an increasing number of birthing hospitals in areas of the state without audiology servicesnearby are conducting the initial outpatient re-screenings, those numbers have been included topresent a more comprehensive view of the follow-up services being provided in Nebraska. In2001, 420 (63%) of the 671 newborns who did not pass a hearing screening during birth
Nebraska Newborn Screening Program 2002/2003 Reportadmission received a follow-up outpatient re-screening or a more comprehensive audiological evaluation. In 2002, the follow-up rate increased to 601 (72%) of the 836 newborns needingadditional re-screening.
In 2003, the follow-up rate further increased to 747 (82%) of the 909 newborns needingadditional follow-up, based on an actual file count of individual follow-up reports received. Afurther analysis of the 747 individual newborn files with follow-up outpatient re-screeningand/or a comprehensive evaluation results indicate that 671 of them did not have a hearing lossbased on the follow-up activity. Of this group, 633 had “referred” during birth admission and38 had been discharged prior to receiving a hearing screening. An additional 20 newborns“referred” on the outpatient re-screening but no additional reports were received so it isunknown if a subsequent evaluation was completed.

Timeliness of Follow-up Re-screening/Testing
The NNHSP Advisory Committee has established that six weeks of age is the targeted deadlinefor completion of hearing screening process for those newborns who have “referred” on theinitial hearing screening during the birth admission or who were discharged prior to beingscreened. In 2003, the 691 completed outpatient hearing screenings were analyzed to determinethe extent to which the six-week goal was achieved (see Chart 2). The average number of daysafter birth that the hearing screening was completed for these 691 infants was 23.8 days. AsChart 2 displays, there are many outpatient re-screenings that occur at about 7 days of age and atbetween 14 to 19 days of age. In total, 604 (87.4%) of the outpatient hearing screeningsoccurred prior to six weeks of age.

Nebraska Newborn Screening Program 2002/2003 Report
Diagnosis of Hearing Loss
The number of infants diagnosed with a hearing loss in Nebraska is reported in two ways: 1)aggregate reports submitted by audiologists of the number of infants shown to have a hearingloss based on follow-up tests (required by Neb. Rev. Stat. §71-4739) and 2) the individualdiagnostic reports submitted to NNHSP by audiologists or primary care physicians. Statuatoryauthority to require audiologists to report on all newborns and infants that receive audiologicalevaluations does not exist, so a one-to-one correspondence between the individual resultsreported to NNHSP and the required annual aggregate reporting does not exist. In 2002,audiologists reported identifying 58 infants born in 2002 with hearing loss and the NNHSPreceived individual reports on 44 of those infants. In 2003, 66 infants born in 2003 werereported as having been diagnosed with a hearing loss, 56 of which the NNHSP receivedindividual reports. Voluntary reporting of individual newborns and infants diagnosed withhearing loss has consistently increased from 39% in 2001 to 85% in 2002 (see Table 8).

Type and Degree of Hearing Loss
Tables 10 and 11 display the number of newborns identified with a hearing loss by the type ofhearing loss (sensorineural, conductive, or undetermined), the degree of hearing loss (rangingfrom mild to profound), and whether the loss was bilateral or unilateral. Tables 10 and 11 do notcompletely represent the number of infants identified with permanent hearing loss because thefigures:• Are based on the individual reports that have been submitted to the NNHSP and, therefore, only
represent from 76% (2002) to 85% (2003) of the infants identified with a hearing loss • Do not indicate if the hearing loss is permanent or temporary, as is often the case with a conductive
hearing loss that results from middle ear dysfunction that is resolved through medical management• Do not include those who were born in the last several months of the year and were not identified
early enough to be included in the statistics for that year. In 2003 the average age at diagnosis ofhearing loss was 80.6 days. While over two thirds were identified at less than 3 months of age,slightly less than one third were identified beyond the targeted 3 months of age.

Summary
• All the current birthing hospitals in Nebraska were conducting newborn hearingscreening by the end of 2003. All but two were conducting the hearing screeningsduring the birth admission.
• The benchmark of 95% of newborns having a hearing screening during birthadmission by December 1, 2003 established by Neb. Rev. Stat. §71-4742 has beenmet. In 2003, birthing hospitals reported screening the hearing of 96.92% ofnewborns.
• The overall refer rate of 3.7% for initial hearing screening during birth admissionwas within national norms during 2003.
• The rate of reported follow-up re-screening and/or diagnostic evaluation hascontinued to improve, increasing from 63% in 2001 to 82% in 2003.
• In 2003, follow-up re-screening occurred within six weeks of birth for 87.4% ofthose newborns in which follow-up activities were initiated. The average age atthe time of the re-screening was 23.8 days.
• The percentage of individual diagnostic evaluation reports submitted to NNHSPcontinued to increase from 39% in 2001 to 85% in 2003.
• The average age at diagnosis of hearing loss was 80.6 days for those reported toNNHSP in 2003 and over two-thirds of evaluations occurred within 3 months ofbirth.
• The incidence of hearing loss identified (2.5 per thousand in 2003) and reported toNNHSP appears to be within the anticipated range of 1 to 3 per thousand. However, more accurate information about the degree and permanence of thehearing loss is needed for increased confidence with this data.
• The current system of manually reporting and tracking only those newborns who“referred” on the initial hearing screening or were discharged without a hearingscreening does contribute to errors within the program.

Part IVPLANS AND ACTIVITIES FOR 2004 -2005
Electronic Data System
A commitment has been made to purchase the optional Newborn Hearing Screening Modulefrom QS Technologies for integration with the new HHS Electronic Vital Record System. Theintegrated system will eliminate the need to manually record, transmit, and track demographicinformation on each newborn who “refers” or is discharged without a hearing screening andincrease the accuracy, consistency, and timeliness of newborn hearing screening informationprovided to the NNHSP by birthing hospitals. It is anticipated that the integrated electronicsystem will be ready for use early in 2005.
Early Head Start ECHO Project
Nebraska has been selected by the National Center for Hearing Assessment and Management toparticipate in the Head Start Hearing Project in 2004-2005. An Early Childhood HearingOutreach (ECHO) team composed of professionals in the hearing health field in Nebraska willtrain Early Head Start staff to screen the hearing of infants and toddlers using otoacousticemissions (OAE) screening techniques. Three Early Head Start programs will participatebeginning in the fall of 2004 with an additional two to three programs joining during the summerof 2005. This project will expand the early hearing detection and intervention activities of theNNHSP.
Revision of Current Systems
As the electronic data system is developed, the NNHSP tracking and surveillance processes willbe modified to accommodate the new system. Communication, reporting, and evaluationprocesses will be revised and enhanced. As part of the revision of reporting processes, particularattention will be paid to clarify the legislative language regarding reporting requirements toincrease the accuracy and usefulness of the data.
Advisory Committee
The Advisory Committee will take on a renewed involvement in program development andenhancement as the electronic tracking and surveillance system is developed to replace themanual tracking system that was created when the NNHSP was first established. The AdvisoryCommittee will also have an increased role with the program as a result of the Early Head StartECHO project expands the scope of follow-up activities of NNHSP. The screening anddiagnostic evaluation protocols established four years ago will be reviewed to incorporateadvances in knowledge, practice, and technology.
