Box 1: According to APIC, an infection preventionist* is typically a registered nurse, physician, epidemiologist, or medical technologist who:
• Helps to prevent healthcare-associated infections (HAIs) by isolating sources of infections and limiting their spread
• Implements infection prevention interventions• Systematically collects, analyzes, and interprets health data in order to plan, implement, evaluate, and disseminate
appropriate public health practices• Trains healthcare staff through instruction and dissemination of information on infection control practices
*APIC stresses the importance of infection prevention interventions. Formerly known as infection control professionals (ICPs), the new designation by APIC for those competent in this arena is infection preventionist.

• BasedonMRSAsurveillanceandriskassessment,finalizeaMRSAmanagementplanintermsoftimeandinterventions(ifneeded),allowingenoughtimetocommunicatetheplantostaffformaximumparticipation.
Example of the Use of the MRSA Risk Assessment Surveillance to Evaluate Incidence on Resident Unit(s)
Step 1: Utilizing MRSA surveillance data to determine MRSA incidence SurveillancedataisevaluatedfornewcasesofMRSAineachresidentunit.ThisresultsinadeterminationofMRSAincidenceratewhichisusedinthefacility’sRiskAssessment.TransmissionofMRSAwithinthefacilitysettingisassumedifthenewcaseofMRSAmeetstheLTCfacility’scasedefinition*ofhealthcare-associatedMRSA.
*Definition of new onset MRSA case: MRSA isolated from clinical culture obtained more than 48 hours after admission to the unit in a resident who had no signs or symptoms of infection on admission and who has no prior MRSA by culture or by history.2
Incidence calculation:
# of newly identified MRSA residents on the unit/month X 1,000# of resident days on the unit/month
= unit-associated MRSA incidence per 1,000 unit resident days

# of new MRSA-positive wound infections on the dementia unit X 1,000# of resident days on the dementia unit

CDC/HICPAC recommendations for patient placement (2006 MDRO guideline):V.A.5.g. Patient placement in hospitals and LTCFs V.A.5.g.i. When single-patient rooms are available, assign priority for these rooms to patients with known or suspected
MDRO colonization or infection. Give highest priority to those patients who have conditions that may facilitate transmission, i.e., uncontained secretions or excretions.
V.A.5.g.ii. When single-patient rooms are not available, cohort patients with the same MDRO in the same room or patient-care area.
V.A.5.g.iii. When cohorting patients with the same MDRO is not possible, place MDRO patients in rooms with patients who are at low risk for acquisition of MDROs and associated adverse outcomes from infection, and are likely to have short lengths of stay.

OBRA mandated that CMS develop a survey process for LTC facilities. The section in the CMS requirements for infection control is as follows: Code of Federal Regulations[Title 42, Volume 3][Revised as of October 1, 2002]From the U.S. Government Printing Office via GPO Access[CITE: 42CFR483.65][Page 514-515]TITLE 42--PUBLIC HEALTHCHAPTER IV--CENTERS FOR MEDICARE & MEDICAID SERVICES, DEPARTMENT OF HEALTH AND HUMAN SERVICES PART 483--REQUIREMENTS FOR STATES AND LONG-TERM CARE FACILITIES--Table of Contents Subpart B—Requirements for Long-term Care Facilities Sec. 483.65 Infection Control.
The facility must establish and maintain an infection control program designed to provide a safe, sanitary, and comfortable environment and to help prevent the development and transmission of disease and infection.
(a) Infection control program. The facility must establish an infection control program under which it: (1) Investigates, controls, and prevents infections in the facility; (2) Decides what procedures, such as isolation, should be applied to an individual resident; and (3) Maintains a record of incidents and corrective actions related to infections.
(b) Preventing spread of infection. (1) When the infection control program determines that a resident needs isolation to prevent the spread of
infection, the facility must isolate the resident. (2) The facility must prohibit employees with a communicable disease or infected skin lesions from direct
contact with residents or their food, if direct contact will transmit the disease. (3) The facility must require staff to wash their hands after each direct resident contact for which hand washing
is indicated by accepted professional practice.
(c) Linens. Personnel must handle, store, process, and transport linens so as to prevent the spread of infection.

Hand Hygiene is Important for Staff
FollowCDCorWHOrecommendationsforhandhygiene.
The “CDC Guideline for Hand Hygiene in Healthcare Settings, 2002” includes the following major components.3
1. Implement a hand hygiene program, including all levels of healthcare providers and other patient contact workers.2. Ask visitors to wash their hands or use an alcohol-based hand rub on entering and leaving the room.3. Wear gloves for all contact with blood, body fluids, and moist body surfaces. Remove gloves after caring for a
patient, when moving from a dirty to clean site on same patient, and before care of the next patient.4. Wash hands or use an alcohol-based hand product after removing gloves.5. Perform hand hygiene before and after contact with a patient.6. Perform hand hygiene before and after contact with the patient’s environment.7. Monitor compliance with hand hygiene for all levels of staff. Provide feedback of rates based on observations or
volume of hand hygiene products used.8. Make improved hand-hygiene adherence an institutional priority and provide appropriate administrative support
and financial resources.

Modes of MRSA TransmissionContact Transmission
ThemostcommonmechanismoftransmissionattributedtoMRSAiscontacttransmission.Contacttransmissionisdividedintotwosubgroups,directandindirect:
• DirecttransmissionaftercontactwiththeMRSA-contaminatedskinorbodyfluidsofapatientwhoiscolonizedorinfectedwithMRSA
• IndirecttransmissionaftercontactwithaMRSA-contaminatedobjectorenvironment
Although anything that contacts a contaminated patient or object can be the source of transmission, the most common vehicles of MRSA spread in healthcare settings are the hands of healthcare staff.

Patients, family members, and visitors can be partners in preventing transmission of infections in healthcare settings.Additional information about Transmission-based Precautions is best provided at the time they are initiated. Fact sheets, pamphlets, and other printed material may include information on the rationale for the additional precautions, risks to household members, room assignment for Transmission-based Precautions purposes, explanation about the use of personal protective equipment by HCWs, and directions for use of such equipment by family members and visitors.

II.N.�.b. Use of barrier precautions by visitors. The use of gowns, gloves, or masks by visitors in healthcare settings has not been addressed specifically in the scientific literature. Some studies included the use of gowns and gloves by visitors in the control of MDROs, but did not perform a separate analysis to determine whether their use by visitors had a measurable impact. Family members or visitors who are providing care or having very close patient contact (i.e., feeding, holding) may have contact with other patients and could contribute to transmission if barrier precautions are not used correctly. Specific recommendations may vary by facility or by unit and should be determined by the level of interaction.
EachLTCfacilitymustdevelopafacilitypolicyregardingtheuseofPPEbyvisitorswhileintransmission-basedisolationrooms.ThepolicyshouldtakeintoaccountvisitororfamilymemberMRSAtransmissionriskbasedonthefacilityriskassessment,applicableguidelines,andbestpracticestandards.ThepolicymustmakeprovisionsforsituationsthatwillrequireenhancedPPEcompliancebyfamiliesandvisitors,includingsituationsduringwhichthereisincreasedtransmission,confirmedoutbreak,orwhenaspecificresidentposesatransmissionrisk.

The CDC’s 12 Step Campaign to Prevent Antimicrobial Resistance in Long-term Care gives clear guidance on the elements of a successful antibiotic stewardship program.
Steps5through8areparticularlyapplicabletothissectionandareprovidedbelow.
Step �. Use local resources- Consult infectious disease experts for complicated infections and potential outbreaks.- Know your local and/or regional data.- Get previous microbiology data for transfer residents.
Step �. Know when to say “no”- Minimize use of broad-spectrum antimicrobials.- Avoid chronic or long-term antimicrobial prophylaxis.- Develop a system to monitor antimicrobial use and provide feedback to appropriate personnel.
Step �. Treat infection, not colonization or contamination- Perform proper antisepsis with culture collection.- Reevaluate the need for continued therapy after 48–72 hours.- Do not treat asymptomatic bacteriuria.
Step �. Stop antimicrobial treatment- When cultures are negative and infection is unlikely.- When infection has resolved.

Action steps: 1. Contract with your reference laboratory to provide facility-specific reports of significant pathogens.2. Contract with your pharmacy for review of prescribing practices over time for all or for specific
antimicrobials. This is sometimes referred to as a DUE (drug utilization evaluation).3. Does your pharmacist review cultures results to evaluate the effectiveness of the antimicrobials prescribed?
If not, ask your medical director to intervene (who, and how will this be done?).

Monette J, Miller MA, Laurier C, et al. Effect of an educational intervention on optimizing antimicrobial prescribing in long-term care facilities. J Am Geriatr Soc. 2007;55:1301–1302.
OBJECTIVE: To assess the effect of an educational intervention aimed at optimizing antimicrobial prescribing in long-term care (LTC) facilities.
DESIGN: Cluster randomized, controlled trial.
SETTING: Eight public LTC facilities in the Montreal area.
PARTICIPANTS: Thirty-six physicians.
INTERVENTION: The educational intervention consisted of mailing an antimicrobial guide to physicians along with their antimicrobial prescribing profile covering the previous three months. Targeted infections were urinary tract, lower respiratory tract, skin and soft tissues, and septicemia of unknown origin. In the prescribing profile, each antimicrobial was classified as adherent or non-adherent to the guide. Physicians in the experimental group received the intervention twice, four months apart, whereas physicians in the control group provided usual care.
MEASUREMENTS: Data on antimicrobial prescriptions were collected over four three-month periods: pre-intervention, post-intervention I, post-intervention II, and follow-up. A generalized estimating equation (GEE) model was used to compare the proportion of non-adherent antimicrobial prescriptions of the experimental and control groups.
RESULTS: By the end of the study, non-adherent antimicrobial prescriptions decreased by 20.5% in the experimental group, compared with 5.1% in the control group. Based on the GEE model, during post-intervention II, physicians in the experimental group were 64% less likely to prescribe non-adherent antimicrobials than those in the control group (odds ratio = 0.36, 95% confidence interval = 0.18–0.73).
CONCLUSION: An educational intervention combining an antimicrobial guide and a prescribing profile was effective in decreasing non-adherent antimicrobial prescriptions. Repetition of the intervention at regular intervals may be necessary to maintain its effectiveness.

Example of Regimen for Decolonization
Mupirocin • Apply approximately one-half of 2% calcium Mupirocin ointment from the 1-gm single-use tube (Bactroban®) into one nostril and the other half of the ointment to the other nostril
• The individual should press the sides of the nose together and gently massage to spread the ointment throughout the inside of the nostrils.
• Continue twice daily for 10 days, avoiding contact of the medication with the eyes.
Chlorhexidine* • Rinse area thoroughly with water, avoiding excessively hot or cold water. • Wash gently from the neck down with the minimum amount of Hibiclens® as necessary. • Rinse thoroughly with warm water. • Continue once daily for 5 days.
*Hibiclens®, containing 4% chlorhexidine gluconate, is known to be toxic. The manufacturer provides the following precautions when using Hibiclens®: Hypersensitivity reactions may occur, particularly in the genital area. Keep away from face and head, since middle ear contact has led to deafness and permanent eye injury may occur following prolonged contact.
