The migration of physicians from sub-Saharan Africa to the United States of America: measures of the African brain drain

Background: The objective of this paper is to describe the numbers; characteristics; and trends in the migration to the United States of physicians trained in sub-Saharan Africa. Methods: We used the American Medical Association 2002 Masterfile to identify and describe physicians who received their medical training in sub-Saharan Africa and are currently practicing in the USA. Results :More than 23of America's 771 491 physicians received their medical training outside the USA; the majority (64) in low-income or lower middle-income countries. A total of 5334 physicians from sub-Saharan Africa are in that group; a number that represents more than 6of the physicians practicing in sub-Saharan Africa now. Nearly 86of these Africans practicing in the USA originate from only three countries: Nigeria; South Africa and Ghana. Furthermore; 79were trained at only 10 medical schools. Conclusions: Physician migration from poor countries to rich ones contributes to worldwide health workforce imbalances that may be detrimental to the health systems of source countries. The migration of over 5000 doctors from sub-Saharan Africa to the USA has had a significantly negative effect on the doctor-to-population ratio of Africa. The finding that the bulk of migration occurs from only a few countries and medical schools suggests policy interventions in only a few locations could be effective in stemming the brain drain

National estimates of physician assistant productivity.

Analysis of productivity data from a nationally representative sample of physician assistants (PAs) showed that PAs performed 61.4 outpatient visits per week compared with 74.2 visits performed by physicians, for an overall physician full-time equivalent (FTE) estimate of 0.83. However, productivity of PAs varies strongly across practice specialty and location, with generalist PAs performing more visits than their specialist counterparts. Rural PA productivity is higher than urban productivity because of the concentration of generalist PAs in rural settings. A generalist PA physician FTE estimate of 0.75 appears to be more accurate than the 0.5 currently under consideration in proposed modifications to Health Personnel Shortage Area designation regulations.

Improving the quality of outpatient care for older patients with diabetes: lessons from a comparison of rural and urban communities.

OBJECTIVE: Our goal was to compare the quality of diabetic care received by patients in rural and urban communities. STUDY DESIGN: We performed a retrospective analysis of claims data captured by the Medicare program. POPULATION: We included all fee-for-service Medicare patients 65 years and older living in the state of Washington who had 2 or more physician encounters for diabetes care during 1994. OUTCOME MEASURES: The outcomes were the extent to which patients received 3 specific recommended services: glycated hemoglobin determination, cholesterol measurement, and eye examination. RESULTS: A total of 30,589 Medicare patients (8.4%) were considered to have diabetes; 29.1% lived in rural communities. Generalists provided most diabetic care in all locations. Patients living in small rural towns received almost half their outpatient care in larger communities. Patients living in large rural towns remote from metropolitan areas were more likely to have received the recommended tests than patients in all other groups. Patients who saw an endocrinologist at least once during the year were more likely to have received the recommended tests. CONCLUSIONS: Large rural towns may provide the best conditions for high-quality care: They are vibrant, rapidly growing communities that serve as regional referral centers and have an adequate-but not excessive-supply of both generalist and specialist physicians. Generalists provide most diabetic care in all settings, and consultation with an endocrinologist may improve adherence to guidelines.

The role of gynecologists in providing primary care to elderly women.

BACKGROUND: Federal legislation has recently been proposed to designate obstetrician-gynecologists (OBGs) as primary care physicians. The Institute of Medicine identifies care unrestricted by problem or organ system as an essential characteristic of primary care. We examined the degree to which OBGs in the state of Washington offer this aspect of primary care to their elderly patients by investigating the type and amount of nongynecologic care they provide. METHODS: Using 1994 Part B Medicare claims data for Washington residents, we identified visits made by women aged 65 years and older to OBGs (N=10,522) and 9 other types of specialists. Diagnoses were classified as in or out of the domain of care traditionally provided by each specialty. Visit volumes, proportion of out of domain visits, and the frequency of diagnoses were reported. RESULTS: Of the patient visits to obstetrician-gynecologists, 12.2% had nongynecologic diagnoses. The median percentage of nongynecologic visits for individual OBGs was 6.7%. Patients who saw OBGs received 15.4% of their overall health care from an OBG; patients who saw family physicians received 42.9% of their total health care from a family physician. CONCLUSIONS: In 1994, a small amount of the care that Washington OBGs provided to their elderly patients was for nongynecologic conditions. Studies are needed to evaluate how the practices of OBGs have changed since the 1996 implementation of a primary care requirement in obstetrics-gynecology residencies, and if adopted, how legislation designating OBGs as primary care physicians affects the health care received by elderly women.

How many rural doctors do we have?

The number of physicians practicing in the nonmetropolitan areas of the United States in relation to population has increased over the past two decades, but more slowly than the number of physicians in metropolitan counties. During the same period, there was a growing acceptance of the perception that the physician work force in the United States exceeded the number necessary to meet the requirements of an efficient health care system. This has caused policy-makers to consider reforming the incentives for training physicians and restricting the entry of physicians from other countries into the United States. The supply figures on which these assessments of oversupply were made are based on "head counts" of the number of licensed, active physicians. By using more detailed data describing the licensed practicing physicians in the states of North Carolina and Washington, and by using estimates of professional activity collected as part of the Socioeconomic Monitoring System of the American Medical Association, estimates of the number of full-time equivalent physicians actually in practice in the two states and the comparative productivity of those physicians were made. Based on the state-level data, the estimates of actively practicing physicians are approximately 14 percent lower than the head-count number in North Carolina and, by using a more conservative estimation method, are approaching a 10 percent lower number than the head-count number in Washington. Using national productivity data, the effective supply of nonmetropolitan physicians appears to have not grown significantly over the past 10 years, and for family physicians the supply has declined by 9 percent. These estimates of the effective physician supply support long-held claims that rural communities continue to experience a severe undersupply of practitioners. These results suggest that the way in which physicians are counted needs to be re-examined, especially in rural places where the ratios of providers to population are more sensitive to small changes in supply.

The distribution of rural female generalist physicians in the United States.

Female physicians are underrepresented in rural areas. What impact might the increasing proportion of women in medicine have on the rural physician shortage? To begin addressing this question, we present data describing the geographic distribution of female physicians in the United States. We examine the geographic distribution of all active U.S. allopathic physicians recorded in the October 1996 update of the American Medical Association Physician Masterfile. Percentages and numbers of female physicians by professional activity, specialty type, and geographic location are reported. Findings reveal there were fewer than 7,000 female allopathic physicians practicing in rural America in 1996. The proportion of generalist female physicians who practice in rural settings was significantly lower than the proportion who practice in urban locations. Although members of the most recent 10-year medical school graduation cohort of female generalist physicians were slightly more likely to practice in rural areas than members of earlier cohorts, female physicians remained significantly underrepresented in rural areas. States varied dramatically in rural female generalist underrepresentation. Should female generalists continue to be underrepresented in rural locations, the rural physician shortage will not be resolved quickly. Effective strategies to improve rural female physician placement and retention need to be identified and implemented to improve rural access to physician care.

Educating generalist physicians for rural practice: how are we doing?

Although about 20 percent of Americans live in rural areas, only 9 percent of physicians practice there. Physicians consistently and preferentially settle in metropolitan, suburban and other nonrural areas. The last 20 years have seen a variety of strategies by medical education programs and by federal and state governments to promote the choice of rural practice among physicians. This comprehensive literature review was based on MEDLINE and Health STAR searches, content review of more than 125 relevant articles and review of other materials provided by members of the Society of Teachers of Family Medicine Working Group on Rural Health. To the extent possible, a particular focus was directed to "small rural" communities of less than 10,000 people. Significant progress has been made in arresting the downward trend in the number of physicians in these communities but 22 million people still live in health professions shortage areas. This report summarizes the successes and failures of medical education and government programs and initiatives that are intended to prepare and place more generalist physicians in rural practice. It remains clear that the educational pipeline to rural medical practice is long and complex, with many places for attrition along the way. Much is now known about how to select, train and place physicians in rural practice, but effective strategies must be as multifaceted as the barriers themselves.

The use of community surveys for health planning: the experience of 56 northwest rural communities.

A rural health services development program of the University of Washington School of Medicine has worked for 15 years with communities throughout the five-state region of Alaska, Idaho, Montana, Washington and Wyoming to strengthen their health systems. In the course of that work, 56 communities were surveyed about their utilization and opinions of local health systems. This database allows the following generalizations to be made about rural Northwest communities: (1) People think highly of their local hospitals, physicians and other key components of the acute medical care system and want their hospitals to remain open. Older respondents are more satisfied than younger respondents; (2) the typical hospital market share is 36 percent, the typical physician market share is 50 percent (3) satisfaction with discrete, well-funded services such as pharmacy, ambulance and dentistry is quite high, whereas satisfaction with mental health and substance abuse treatment is significantly lower; (4) the most commonly cited serious problems in surveyed communities were "too few physicians or- services" and "care is too expensive"; and (5) there is great variation between communities in both satisfaction and utilization.

US medical schools and the rural family physician gender gap.

BACKGROUND: Women comprise increasing proportions of medical school graduates. They tend to choose primary care but are less likely than men to choose rural practice. METHODS: This study used American Medical Association masterfile data on 1988-1996 medical school graduates to identify the US medical schools most successful at producing rural family physicians and general practitioners of both genders. RESULTS: The number of listed rural female family physician or general practitioner graduates among schools ranged from 0-27 (0% to 4.4% of each school's 1988-1996 graduates). There were approximately twice as many male as female rural family physicians and general practitioners. Publicly funded schools produced more rural female family physicians and general practitioners than their privately funded counterparts. CONCLUSIONS: Our findings suggest that a few schools, most of them public, may serve as models for schools that aim to train women who later enter rural practice.

Emergency department use by the rural elderly.

This study uses Medicare data to compare emergency department (ED) use by rural and urban elderly beneficiaries. The U.S. Health Care Financing Administration's National Claims File was used to identify services provided to Medicare beneficiaries in Washington State in 1994. Patients were classified by urban, adjacent rural, or remote rural residence. We identified ED visits and associated diagnostic codes, assigned severity levels for presenting conditions, and determined the specialties of physicians providing ED services. The rural elderly living in remote areas are 13% less likely to visit the ED than their urban counterparts. Causes of ED use by the elderly do not vary meaningfully by location. Most ED visits by this group are for conditions that seem appropriate for this setting. Given the similarity of diagnostic conditions associated with ED visits, rural EDs must be capable of dealing with the same range of emergency conditions as urban EDs.

The effect of the doctor-patient relationship on emergency department use among the elderly.

OBJECTIVES: This study sought to determine the rate of emergency department use among the elderly and examined whether that use is reduced if the patient has a principal-care physician. METHODS: The Health Care Financing Administration's National Claims History File was used to study emergency department use by Medicare patients older than 65 years in Washington State during 1994. RESULTS: A total of 18.1% of patients had 1 or more emergency department visits during the study year; the rate increased with age and illness severity. Patients with principal-care physicians were much less likely to use the emergency department for every category of disease severity. After case mix, Medicaid eligibility, and rural/urban residence were controlled for, the odds ratio for having any emergency department visit was 0.47 for patients with a generalist principal-care physician and 0.58 for patients with a specialist principal-care physician. CONCLUSIONS: The rate of emergency department use among the elderly is substantial, and most visits are for serious medical problems. The presence of a continuous relationship with a physician--regardless of specialty--may reduce emergency department use.

Reproductive health services in rural Washington State: scope of practice and provision of medical abortions, 1996-1997.

OBJECTIVES: This study explored reproductive health care in rural Washington State, reasons given by providers for not offering abortions, and providers' willingness to use medical abortifacients. METHODS: Physicians, midwives, nurse practitioners, and physician assistants in rural Washington completed an inventory of reproductive health services that they provide, whether and why they do not perform abortions, and whether they would use medical abortifacients. RESULTS: Of the respondents, 89.2% reported providing reproductive health care. Only 1.2% reported performing surgical abortions, and 26.1% indicated that they would probably prescribe medical abortifacients. CONCLUSIONS: Few providers offer surgical abortions in rural Washington. Greater numbers report a willingness to prescribe medical abortifacients.

Rural and urban physicians: does the content of their Medicare practices differ?

Rural and urban areas have significant differences in the availability of medical technology, medical practice structures and patient populations. This study uses 1994 Medicare claims data to examine whether these differences are associated with variation in the content of practice between physicians practicing in rural and urban areas. This study compared the number of patients, outpatient visits, and inpatient visits per physician in the different specialties, diagnosis clusters, patient age and sex, and procedure frequency and type for board-certified rural and urban physicians in 12 ambulatory medical specialties. Overall, 14.4 percent of physicians in the 12 specialties practiced exclusively in rural Washington, with great variation by specialty. Rural physicians were older and less likely to be female than urban physicians. Rural physicians saw larger numbers of elderly patients and had higher volumes of outpatient visits than their urban counterparts. For all specialty groups except general surgeons and obstetrician-gynecologists, the diagnostic scope of practice was specialty-specific and similar for rural and urban physicians. Rural general surgeons had more visits for gastrointestinal disorders, while rural obstetrician-gynecologists had more visits out of their specialty domain (e.g., hypertension, diabetes) than their urban counterparts. The scope of procedures for rural and urban physicians in most specialties showed more similarities than differences. While the fund of knowledge and outpatient procedural training needed by most rural and urban practitioners to care for the elderly is similar, rural general surgeons and obstetrician-gynecologists need training outside their traditional specialty areas to optimally care for their patients.

Hospital peer review and the National Practitioner Data Bank: clinical privileges action reports.

CONTEXT: The National Practitioner Data Bank (NPDB) is believed to be an important source of information for peer review activities by the majority of those who use it. However, concern has been raised that hospitals may be underreporting physicians with performance problems to the NPDB. OBJECTIVE: To examine variation in clinical privileges action reporting by hospitals to the NPDB, changes in reporting over time, and the association of hospital characteristics with reporting. DESIGN: Retrospective cohort study of privileges action reports to the NPDB between 1991 and 1995, linked with the 1992 and 1995 databases from the Annual Survey of Hospitals conducted by the American Hospital Association. SETTING AND PARTICIPANTS: A total of 4743 short-term, nonfederal, general medical/surgical hospitals throughout the United States that were continuously open between 1991-1995 and registered with the NPDB. MAIN OUTCOME MEASURES: (1) Reporting of 1 or more privileges actions during the 5-year study period and (2) privileges action reporting rates (numbers of actions reported per 100000 admissions). RESULTS: Study hospitals reported 3328 privileges actions between 1991 and 1995; 34.2% reported 1 or more actions during the period. The range of privileges action reporting rates for these hospitals was 0.40 to 52.27 per 100000 admissions, with an overall rate of 2.36 per 100000 admissions. The proportion of hospitals reporting an action decreased from 11.6% in 1991 to 10.0% in 1995 (P=.008). After adjustment for other factors, urban hospitals had significantly higher reporting than rural hospitals (adjusted odds ratio [OR], 1.21 [95% confidence interval [CI], 1.02-1.43]), while members of the Council of Teaching Hospitals of the Association of American Medical Colleges had significantly lower reporting than nonmembers (adjusted OR, 0.54 [95% CI, 0.40-0.73]). There were notable regional differences in reporting, with the east south Central region having the lowest rate per 100000 admissions (1.49 [95% CI, 1.33-1.65]). CONCLUSIONS: The results of this study indicate a low and declining level of hospital privileges action reporting to the NPDB. Several potential explanations exist, 1 of which is that the information reported to the NPDB is incomplete.

Dimensions of retention: a national study of the locational histories of physician assistants.

This study describes the locational histories of a representative national sample of physician assistants and considers the implications of observed locational behavior for recruitment and retention of physician assistants in rural practice. Through a survey, physician assistants listed all the places they had practiced since completing their physician assistant training, making it possible to classify the career histories of physician assistants as "all rural," "all urban," "urban to rural" or "rural to urban." The study examined the retention of physician assistants in rural practice at several levels: in the first practice, in rural practice overall and in states. Physician assistants who started their careers in rural locations were more likely to leave them during the first four years of practice than urban physician assistants, and female rural physician assistants were slightly more likely to leave than men. Those starting in rural practice had high attrition to urban areas (41 percent); however, a significant proportion of the physician assistants who started in urban practice settings left for rural settings (10 percent). This kept the total proportion of physician assistants in rural practice at a steady 20 percent. While 21 percent of the earliest graduates of physician assistant training programs have had exclusively rural careers, only 9 percent of physician assistants with four to seven years of experience have worked exclusively in rural settings. At the state level, generalist physician assistants were significantly more likely to leave states with practice environments unfavorable to physician assistant practice in terms of prescriptive authority, reimbursement and insurance.

Abortion services in rural Washington State, 1983-1984 to 1993-1994: availability and outcomes.

CONTEXT: Fewer rural health providers offer abortion services than a decade ago. It is unknown how the reduction in service availability has affected women's pregnancy outcomes, the extent to which they must travel to obtain an abortion or whether abortions are delayed as a result. METHODS: Population, birth and fetal death data, as well as pregnancy termination reports, obtained from Washington State were used to calculate abortion rates and ratios and birthrates for Washington residents in 1983-1984 and in 1993-1994. Residence of abortion patients was classified by county only, and location of providers was recorded as large urban county, small urban county, large rural county or small rural county. Distances that women traveled to obtain an abortion were calculated. Chi-square tests were used to compare urban and rural rates and ratios within time periods, and to compare changes that occurred between time periods. RESULTS: Birthrates and abortion rates decreased for both rural and urban Washington women between 1983-1984 and 1993-1994, but the magnitude of the decrease was greater for rural women. The rural abortion rate fell 27%, from 14.9 abortions per 1,000 women to 10.9 per 1,000, while the urban rate dropped 17%, from 21.8 to 18.2 per 1,000. The decline in the abortion rate was larger for adolescents than it was for other age-groups. In rural areas, the abortion rate decreased from 16.5 per 1,000 adolescents aged 10-19 in 1983-1984 to 10.8 per 1,000 in 1993-1994, while it declined from 23.3 per 1,000 to 16.9 per 1,000 in urban areas. From the earlier to the later time period, rural women traveled on average 12 miles farther each way to obtain an abortion, and the proportion who obtained the procedure in a rural county decreased from 25% to 3%. In the earlier time period, 62% of rural women traveled 50 miles or more to obtain an abortion, compared with 73% in 1993-1994. From 1983-1984 to 1993-1994, the proportion of rural women who traveled out of state for an abortion increased from 8% to 14%. The proportion of rural women terminating their pregnancy after the first trimester increased from 8% in 1983-1984 to 15% in 1993-1994. CONCLUSION: Rural Washington women are traveling farther and more often to urban and out-of-state locations for abortion services, and are obtaining their abortions at a later gestational age, which is associated with a decade-long decline in the number of abortion providers.

PIP: The availability and outcome of abortion services as of 1983-84 and 1993-94 in rural Washington State were investigated. The population data include birth, fetal death and pregnancy termination which came from the vital statistics data compiled by Washington State. Results showed that birth rates and abortion rates decreased throughout the state from 1983-84 to 1993-94. The magnitude of the drop in abortion rates was significantly greater in rural than in urban women (p 0.01). The rural abortion rate fell 27% compared with a 17% drop in the urban rate. The declination in the abortion rate was larger for adolescents than other age groups. The abortion rate for adolescents aged 10-19 years dropped 35% in rural areas and 28% in urban areas. 12 miles increased the distance that rural women traveled to obtain abortion. The proportion of rural women having abortions decreased significantly from 25% to 3%. During 1983-84, 62% traveled 50 miles to obtain abortion compared with 73% in 1993-94. In both time periods, the proportion of rural women who traveled out of state for an abortion increased from 8% to 14%. Furthermore, the proportion of women terminating their pregnancy after the first trimester increased from 8% in 1983-84 to 15% in 1993-94. More work is needed to understand the relationships among provider availability, other factors influencing decision-making and pregnancy outcomes.

Influence of provider characteristics and insurance status on maternal serum alpha-fetoprotein screening.

BACKGROUND: The maternal serum alpha-fetoprotein test (MSAFP) was developed to screen for neural tube defects. Little is known about the adoption of the MSAFP test. This study examines the effect of provider specialty and geographic location and patient insurance status on MSAFP test use in Washington State. METHODS: We conducted a retrospective cohort study of MSAFP use in low-risk obstetric patients of five provider groups. MSAFP use was examined for Medicaid and privately insured patients, as well as for the patients of the five provider types. RESULTS: Patients of urban and rural obstetrician-gynecologists were most likely to have MSAFP testing (80.4 percent and 77.0 percent, respectively); patients of urban certified nurse midwives and rural family physicians were least likely to have MSAFP testing (64.2 percent and 62.2 percent, respectively). Patients of certified nurse midwives were more likely to decline MSAFP testing when offered (26.1 percent). Medicaid-insured women were significantly less likely to have MSAFP testing than privately insured women (60.5 percent versus 79.1 percent, P < or = 0.05). CONCLUSIONS: Providers and patients did not uniformly use MSAFP screening. Efforts should be made to ensure that all patients are adequately informed of screening tests for neural tube defects.

Job satisfaction among rural physician assistants.

Because increasing numbers of physicians are being trained in specialized medicine, health professional shortage areas remain common in the United States, and the role of physician assistants (PAs) in health services provision is becoming increasingly important, especially in rural and underserved areas. By most accounts, there is a shortage of PAs in the United States, particularly in rural areas. A nationwide survey was conducted in 1994 to determine what attracted PAs to rural settings and what they found satisfying about their work and community. This study involved a random sample of 1,263 PAs who practiced in rural (nonmetropolitan) areas of the United States. A 15-item scale was developed to measure job satisfaction. A statistical model was tested for its ability to predict levels of job satisfaction using multiple regression analysis. Independent variables included demographics, practice, and community factors. Findings indicated that rural PAs were generally satisfied with their work. The most significant predictors of satisfaction included practice factors (e.g., importance of autonomy and a good relationship with the supervising physician), extent of practice responsibilities (e.g., regular and on-call hours and the percentage of PAs' patient load that was not discussed with the supervising physician), and community factors (e.g., community satisfaction).

A comparison of practice characteristics among physician assistants in HMO and non-HMO settings.

Health maintenance organizations (HMOs) have continued to grow in both number and enrollment. A major goal of HMOs and other managed care structures is the containment of health care costs. The utilization of physician assistants (PAs) would seem to nicely mesh with these organizations. This study examines the roles, productivity, and clinical autonomy of PAs in HMO settings. In this examination, PAs working with HMOs are compared with PAs working in non-HMO settings, both urban and rural. The results of the study document that PAs working in HMO environments primarily focus on ambulatory care, with few inpatient or administrative responsibilities. Further, PAs working in HMO settings have a highly autonomous practice with approximately 70 percent of patient visits never being discussed with a supervising physician. Lastly, the results suggest that many of the attributes of an HMO practice are found in rural practice as well. Consequently, as HMOs reach out farther into rural America, PAs in rural settings will have fewer practice modifications to make than urban PAs in their transition to practice in an HMO modality.
