Current HPSA Guidelines
Health Professional Shortage Areas (HPSA)•Primary care, dental health, and mental health•Geographic, special population, and facility •Designation criteria
• A defined rational service area• 3,500 to 1 population to provider ratio (3,000
to 1 for special populations or high need geographic)
• Services deemed inaccessible in contiguous areas

Current MUA/P Guidelines
Medically Underserved Area or Population (MUA/P)•Primary care only•Geographic or special population•Designation criteria
• A defined rational service area• Weighted score of 62 or less based on
• Population to provider ratio• Percent of the population under 100% of the
Federal Poverty Level• Percent of the population 65 years of age or
older• Infant mortality rate
•Governor’s Exceptions

What are Shortage Area Designations Used for?
HPSA Designations are used for:• National Health Service Corp placements• J-1 Visa Waiver placements• Doctors Across New York placements• 10% Medicare enhanced rate (primary care geographic)
Medically Underserved Area/Population are used for:• Federal 330 new sites or expansion funding• J-1 Visa Waiver placements• Doctors Across New York placements

Proposed 2008 Guidelines
• Proposed 2008 Guidelines• Merged HPSA and MUA/P• Adjusted the population to account for
• Age• Mortality• Race/ethnicity• Poverty• Population density
• Eliminated contiguous area analysis if a state has a statewide set of rational service areas
• Included midwifes, nurse practitioners, and physician assistants in the primary care provider count

HEAL 9 Health Planning Grant
Problem 1: The current approach used to identify and designate primary care shortage areas in New York is fragmented
Problem 2: New York is not prepared for potential changes in shortage area guidelines
Solution: In collaboration with CHCANYS, conduct a comprehensive statewide primary care assessment Rational Service Area (RSA) development Primary care provider data collection Primary care capacity assessment

The View from 10,000 Feet: We Know What We Don’t Know
The extent to which NPs, PAs, and midwives provide primary care services
How many community-based primary care physicians provide care to underserved populations
How far people travel (beyond county boundaries) for primary care services
Impact of expanded access to health insurance on demand for primary care
How the denominator is changing – a smaller, but older population upstate

METHODS

Developing RSAs: Cluster Analysis
Used by the Economic Research Service of the U.S. Department of Agriculture to construct commuting zones based on 1980 and 1990 journey-to-work data
Adapted this methodology for primary care RSAs throughout the state by analyzing patient commuting patterns for primary care office visits
![Page 17: A New Methodology for Identifying Primary Care Rational Service Areas Long Island Robert Martiniano, Project Director, CHWS David Armstrong, Ph.D., CHWS](https://reader036.vdocuments.site/reader036/viewer/2022081414/55140735550346e7488b4ba3/html5/thumbnails/17.jpg)

Comparison to Primary Care Service Areas (PCSAs)
PCSAs are a potential alternative to creating RSAs
Created by Goodman et al. (Dartmouth) Used Medicare claims data to assign
each zip code to a PCSA based on where the largest proportion of patients go for primary care
![Page 18: A New Methodology for Identifying Primary Care Rational Service Areas Long Island Robert Martiniano, Project Director, CHWS David Armstrong, Ph.D., CHWS](https://reader036.vdocuments.site/reader036/viewer/2022081414/55140735550346e7488b4ba3/html5/thumbnails/18.jpg)

Data Sources for Developing RSAs
Medicare Medicaid Health plan association data from
11 major private insurers Data on the uninsured from
community health centers
![Page 19: A New Methodology for Identifying Primary Care Rational Service Areas Long Island Robert Martiniano, Project Director, CHWS David Armstrong, Ph.D., CHWS](https://reader036.vdocuments.site/reader036/viewer/2022081414/55140735550346e7488b4ba3/html5/thumbnails/19.jpg)

Methodology
The basic unit of data analysis was patient care commuting flows between zip codes.
From each data set: Patient residential zip code Primary care physician zip code
In some datasets patients had a designated PCP
In other datasets, primary care visits identified by CPT codes and physician specialty were used to determine a PCP
Zip codes were combined based on commuting patterns using a cluster analysis
Zip codes were then translated into townships (rural areas) and census tracts (urban areas)

Statewide, 317 Preliminary Primary Care RSAs Were Created Using this Methodology

MUA Designations Under Current Rules
No RSAs in either Nassau or Suffolk counties would qualify for MUAs.
There is current one Governor’s Exception designation in Nassau County.
There are two MUA/P designations in Suffolk County.

Next Steps in the Project
Continue with local meetings Develop and compare RSAs using the
different insurance types, i.e., Medicaid, Medicare, commercial, and uninsured
Finalize methodology and/or RSAs
![Page 33: A New Methodology for Identifying Primary Care Rational Service Areas Long Island Robert Martiniano, Project Director, CHWS David Armstrong, Ph.D., CHWS](https://reader036.vdocuments.site/reader036/viewer/2022081414/55140735550346e7488b4ba3/html5/thumbnails/33.jpg)
33
Looking Ahead: Using RSAs Create a more systematic and streamlined
approach to the identification and designation of HPSAs and MUA/Ps
Inform impact analyses for proposed changes to update HPSA and MUA/P methodologiesHealth reform statute requires ‘negotiated rule
making’ for revisions to current methodologies Support local health planning efforts Inform state policies and programs

Assessing the RSAs
![Page 35: A New Methodology for Identifying Primary Care Rational Service Areas Long Island Robert Martiniano, Project Director, CHWS David Armstrong, Ph.D., CHWS](https://reader036.vdocuments.site/reader036/viewer/2022081414/55140735550346e7488b4ba3/html5/thumbnails/35.jpg)
35
Questions to Consider When Assessing the Proposed RSAs
• Do these RSAs seem reasonable based on your knowledge of the region?
• Are there unique circumstances within your region that could affect travel patterns to primary care services, including:
• Changes in the service delivery system (expansions or reductions) since 2007?
• Physical barriers (highway construction, bridge closures, etc.)?
• Changes in the availability of public transportation since 2007?
• Special populations that may not have been considered in the assessment of commuting patterns?
• Any other issues that could affect the travel patterns of individuals to primary care services?
