Community Health Centers and racial/ethnic disparities in healthy life.

This study examined disparities in health status among individuals of different racial and ethnic groups cared for by the nation's community health centers (CHCs) and compared these results with the findings for individuals using non-CHC sites as their usual source of care. The sample consisted of CHC users from the 1994 CHC User Survey and non-CHC users from the 1994 National Health Interview Survey. Bivariate comparisons were made between individuals' race/ethnicity and their experience of healthy life, an integrated measure that incorporates both activity limitation and self-perceived health status. Multiple regressions were followed to examine the independent association of race/ethnicity with healthy life experience for both CHC and non-CHC users while controlling for sociodemographic correlates of health. Among CHC users, racial and ethnic minorities did not have worse health than whites, but among non-CHC users there were significant racial and ethnic disparities: whites experienced significantly healthier life than both blacks and non-white Hispanics. These findings persisted after controlling for sociodemographic correlates of health. The results indicate that while racial/ethnic disparities in health persist nationally, these disparities do not exist within CHCs, safety-net providers with an explicit mission to serve vulnerable populations.

Inequality in America: the contribution of health centers in reducing and eliminating disparities in access to care.

Reducing and eliminating health status disparities by providing access to appropriate health care is a goal of the nation's health care delivery system. This article reviews the literature that demonstrates a relationship between access to appropriate health care and reductions in health status disparities. Using comprehensive site-level data, patient surveys, and medical record reviews, the authors present an evaluation of the ability of health centers to provide such access. Access to a regular and usual source of care alone can mitigate health status disparities. The safety net health center network has reduced racial/ethnic, income, and insurance status disparities in access to primary care and important preventive screening procedures. In addition, the network has reduced low birth weight disparities for African American infants. Evidence suggests that health centers are successful in reducing and eliminating health access disparities by establishing themselves as their patients' usual and regular source of care. This relationship portends well for reducing and eliminating health status disparities.

The impact of managed care on the mix of vulnerable populations served by community health centers.

This article examined the impact of managed care involvement on vulnerable populations served by community health centers (CHCs), while controlling for center rural-urban location and size, and found that centers involved in managed care have served a significantly smaller proportion of uninsured patients but a higher proportion of Medicaid users than those not involved in managed care. The results suggest that the increase in Medicaid managed care patients may lead to a reduced capacity to care for the uninsured, thus hampering CHCs from expanding access to health care for the medically indigent.

The National Health Service Corps for the 21st century.

The National Health Service Corps (NHSC) was created in 1970 to provide primary health care clinicians for the underserved. The article includes a review of the peer-reviewed and intragovernmental literature on the NHSC program from 1971 to 1998 and also presents a current profile of the program. Despite significant increases in NHSC field strength since 1991, the 2,439 clinicians meet only 12% of the need for primary health care providers in underserved areas. While the NHSC has successfully addressed clinician diversity and retention issues, community and site development remain barriers to increasing access. Most communities in need are not ready to recruit and support clinicians. The NHSC of the next millennium must work with the neediest communities to reach the appropriate stage of readiness. Only after completing the necessary "preplacement" activities can the NHSC assist in the recruitment and placement of clinicians to increase access.

Eliminating primary care health professional shortage areas: the impact of Title VII generalist physician education.

Most policy-makers and researchers agree that although the United States is headed for a significant physician surplus, problems of equity in access to care still remain. To help meet this challenge, Title VII of the Public Health Service Act focuses on producing generalist physicians to serve in medically underserved areas (MUAs). This study estimates the impact Title VII support for generalist training has on reducing and eliminating health professional shortage areas (HPSAs) under multiple scenarios that vary either the Title VII funding level or the percentage of Title VII-funded program graduates who practice in MUAs. For each scenario, the number of Title VII-funded residency graduates who initially practice in MUAs and the time it would take to eliminate HPSAs are estimated. Using 1996 rates, the analysis predicts that 1,214 generalist physicians will enter practice in HPSAs annually, leading to elimination of HPSAs in 24 years. In 1997, Title VII-funded programs increased the rate of graduates entering HPSAs, resulting in 1,357 providers and reducing the time for HPSA elimination to 15 years. Doubling the funding for these programs would increase the number of Title VII-funded generalist physicians entering MUAs and could decrease the time for HPSA elimination to as little as 6 years. The study concludes that eliminating HPSAs requires broader Title VII influence and continuous improvement in rates of production of graduates who practice in MUAs. Without Title VII graduates and continuous improvement of Title VII program, MUA rates, the number of HPSAs and the number of Americans with reduced access to essential health care will continue to expand.

Availability of primary care providers and pharmacists in the United States.

OBJECTIVE: To determine the rural distribution of primary care providers (primary care physicians, physician assistants, nurse practitioners, and nurse midwives) and pharmacists. DESIGN: Five-digit ZIP code mapping to study the availability of primary care providers and pharmacists, alone and in combinations, in rural areas and ZIP code-based health professional shortage areas (HPSAs). National averages for annual physician visits for hypertension, asthma, and diabetes were used to estimate the sufficiency of the rural physician supply. SETTING: Rural areas of the United States. RESULTS: In rural areas, all providers were present in lower densities than national averages, particularly in HPSAs. The primary care physician supply was insufficient to meet national averages for office visits for hypertension, asthma, and diabetes. Among available providers, the most prevalent co-presence was primary care physician with pharmacist. HPSAs showed very low physician density (1 per 22,122), and the most prevalent providers were pharmacists. States varied widely in provider density. CONCLUSION: Despite longstanding efforts and the expansion of managed care, primary care providers remain in short supply in rural areas, especially ZIP code-based HPSAs. Making the best use of available providers should be encouraged. The continued shortfall of primary care providers in rural areas, particularly HPSAs, makes it logical to use other available providers and combinations to increase health care access. Pharmacists could increase care for patients with conditions treated with medications. Other available providers, based on skills and work site, could also offset shortages.

The impact of Title VII departmental and predoctoral support on the production of generalist physicians in private medical schools.

Although federal support for medical education comes from several sources, only 1 targets generalist education--Title VII of the Public Health Service Act. With governmental streamlining and downsizing, the federal investment in medical education should be evaluated. We tested the relationship between 2 Title VII authorities and presence of a medical school generalist training infrastructure, and the relationship between this infrastructure and generalist production. Based on our definitions for receipt of Title VII support, generalist infrastructure, and generalist production, we found that, for private schools, sustained receipt of Title VII funds directed for undergraduate medical education is positively associated with presence of family medicine departments, which is positively associated with higher rates of generalist production. Establishment and maintenance of family medicine departments in private schools and their generalist production are positively associated with Title VII support. Title VII support in public schools, the major generalist producers, has less of a unique measurable impact on generalist production.

Downsizing the physician workforce.

OBJECTIVE: To estimate the need for downsizing the physician workforce in a changing health care environment. METHODS: First assuming that 1993 physician-to-population ratios would be maintained, the authors derived downsizing estimates by determining the annual growth in the supply of specialists necessary to maintain these ratios (sum of losses from death and retirement plus increase necessary to parallel population growth) and compared them with an estimate of the number of new physicians being produced (average annual number of board certificates issued between 1990 and 1994). Then, assuming that workforce needs would change in a system increasingly dominated by managed care, the authors estimated specialty-specific downsizing needs for a managed care dominated environment using data from several sources. RESULTS: To maintain the 1993 199.6 active physicians per 100,000 population ratio, 14,644 new physicians would be needed each year. Given that an average of 20,655 physicians were certified each year between 1990 and 1994, at least 6011 fewer new physicians were needed annually to maintain 1993 levels. To maintain the 132.2 ratio of active non-primary care physicians per 100,000 population, the system needed to produce 9698 non-primary care physicians per year, because an average of 14,527 new non-primary care physicians entered the workforce between 1990 and 1994, downsizing by 4829, or 33%, was needed. To maintain the 66.8 active primary care physicians per 100,000 population ratio, 4946 new primary care physicians were needed per year, since primary care averaged 6128 new certifications per year, a downsizing of 1182, or 20% was indicated. Only family practice, neurosurgery, otolaryngology, and urology did not require downsizing. Seventeen medical and hospital-based specialties, including 7 of 10 internal medicine subspecialties, needed downsizing by at least 40%. Less downsizing in general was needed in the surgical specialties and in psychiatry. A managed care dominated-system would call for greater downsizing in most of the non-primary care specialties. CONCLUSION: These data support the need for downsizing the nation's physician supply, especially in the internal medicine subspecialties and hospital support specialties and to a lesser extent among surgeons and primary care physicians.

Matching physician supply and requirements: testing policy recommendations.

Managed care has been growing and likely will increase market share. This movement will require fundamental alterations in the number and specialty distribution of physicians. Under current production, future supply does not appear well-matched with requirements. Although the adequacy of generalist supply is of concern, the oversupply of specialists is the overriding problem. Neither reducing the number of first-year residents nor increasing the generalist output alone would bring both generalist and specialist supply within requirement ranges. Combining an increase in generalist production to 50% with a reduction in first-year residents to 110% of the number of U.S. medical graduates would minimize the projected specialty surplus while maintaining generalist supply within the requirement range.

Medical migration and the physician workforce. International medical graduates and American medicine.

OBJECTIVE: Because of the size and growth of the international medical graduate (IMG) contribution to graduate medical education (GME) in the United States, and subsequently to the US physician workforce, it is essential to understand the demographics and patterns of IMG training and practice as well as the routes of entry into the United States. DATA SOURCES: Published data from the American Medical Association, the American Osteopathic Association, and the Association of American Medical Colleges; tabular runs of county-level data contained on the Bureau of Health Professions' Area Resource File. RESULTS: The majority of IMGs who participate in GME in the United States ultimately enter US practices. A significant proportion of exchange visitors eventually enter into permanent practice in the United States, contrary to the intent of the J-1 visa-based GME training as an international educational exchange program. International medical graduates gravitate toward initial residency programs in internal medicine and pediatrics, many of which have unfilled positions; however, IMGs subspecialize at a disproportionately high rate, reducing their net contribution to the generalist pool. Patterns of ultimate practice location of IMGs parallel the patterns of US medical graduates (USMGs). CONCLUSIONS: In recent years, participation of IMGs in GME and practice has increased significantly. Most IMGs in GME are not exchange visitors, but are either permanent residents or US citizens. Patterns of specialization and location of IMGs ultimately mirror those of USMGs. National IMG policy must be examined in light of the projected surplus of physicians in the United States. The best option for long-term control of the number of physicians in practice, USMG or IMG, is a system of specifying the number of GME positions nationally.

Managed care on the march: will physicians meet the challenge?

The health care delivery system in the United States is in transition. Increasingly managed care plans are gaining in predominance. The proliferation of managed care systems will have an impact on the demand and requirements for physicians. This paper attempts to project and estimate requirements for physicians in 2000 and 2020, assuming that the health care system will continue to be dominated by managed care. The projections are then compared to forecasts of physician supply under two separate physician production scenarios. The authors discuss the adequacy of the future physician workforce to provide services required by a health care system dominated by managed care.

Balance and limits: modeling graduate medical education reform based on recommendations of the Council on Graduate Medical Education.

National commissions, medical philanthropies, scholars, and policy analysts agree that the key to improved health care access and cost containment is a physician workforce built on a generalist foundation. They propose a national system to allocate a specific and limited number of graduate medical education (GME) positions. The Council on Graduate Medical Education recommended that training positions be limited to 110 percent of the graduates of U.S. allopathic and osteopathic medical schools and that the system graduate 50 percent into primary care practice (50/50-110 proposal). The 50/50-110 option would significantly modify GME training: surgical and support specialty positions would be reduced, and increased numbers of medical and pediatric residents would enter general practice. This workforce composition would facilitate provision of universal health care access and help control costs--the basic tenets of reform.
