Rural-urban differences in primary care physicians' practice patterns, characteristics, and incomes

CONTEXT: Low salaries and difficult work conditions are perceived as a major barrier to the recruitment of primary care physicians to rural settings. PURPOSE: To examine rural-urban differences in physician work effort, physician characteristics, and practice characteristics, and to determine whether, after adjusting for any observed differences, rural primary care physicians' incomes were lower than those of urban primary care physicians. METHODS: Using survey data from actively practicing office-based general practitioners (1,157), family physicians (1,378), general internists (2,811), or pediatricians (1,752) who responded to the American Medical Association's annual survey of physicians between 1992 and 2002, we used linear regression modeling to determine the association between practicing in a rural (nonmetropolitan) or urban (standard metropolitan statistical area) setting and physicians' annual incomes after controlling for specialty, work effort, provider characteristics, and practice characteristics. FINDINGS: Rural primary care physicians' unadjusted annual incomes were similar to their urban counterparts, but they tended to work longer hours, complete more patient visits, and have a much greater proportion of Medicaid patients. After adjusting for work effort, physician characteristics, and practice characteristics, primary care physicians who practiced in rural settings made $9,585 (5%) less than their urban counterparts (95% confidence intervals: -$14,569, -$4,602, P < .001). In particular, rural practicing general internists and pediatricians experienced lower incomes than did their urban counterparts. CONCLUSIONS: Addressing rural physicians' lower incomes, longer work hours, and greater dependence on Medicaid reimbursement may improve the ability to ensure that an adequate supply of primary care physicians practice in rural settings.     

Medical Training Debt and Service Commitments: The Rural Consequences

This study assesses how student loan debt and scholarships, loan repayment and related programs with service requirements influence the incomes young physicians seek and attain, influence whether they choose to work in rural practice settings and affect the number of Medicaid-covered and uninsured patients they see. Data are from a 1999 mail survey of a national probability sample of 468 practicing family physicians, general internists and pediatricians who graduated from U.S. medical schools in 1988 and 1992. A majority of these generalist physicians recalled "moderate" or "great" concern for their financial situations before, during and after their training. Eighty percent financed all or part of their training with loans, and one-quarter received support from federal, state or community-sponsored scholarship, loan repayment and similar programs with service obligations. In their first job after residency, family physicians and pediatricians with greater debt reported caring for more patients insured under Medicaid and uninsured than did those with less debt. For no specialty was debt associated with physicians' income or likelihood of working in a rural area. Physicians serving commitments in exchange for training cost support, compared to those without obligations, were more likely to work in rural areas (33 vs. 7 percent, respectively, p < 0.001) and provided care to more Medicaid-covered and uninsured patients (53 vs. 29 percent, p < 0.001), but did not differ in their incomes ($99,600 vs. $93,800, p = 0.11). Thus, among physicians who train as generalists, the high costs of medical education appear to promote, not harm, national physician work force goals by prompting participation in service-requiring financial support programs and perhaps through increasing student borrowing. These positive outcomes for generalists should be weighed against other known and suspected negative consequences of the high costs of training, such as discouraging some poor students from medical careers altogether and perhaps influencing some medical students with high debt not to pursue primary care careers.     

The organization of medical practice and primary care physician income

This study investigates the effect of the organization of medical practice, e.g., solo, fee-for-service group, or health maintenance organization (HMO) settings, on primary care physicians' net incomes. Using pooled data on 2,372 primary care physicians, multivariate regression analysis is used to adjust physicians' 1979 net incomes for differences in medical specialty, workload, sex, and experience before estimating the effects of the organization of medical practice. Among HMO physicians, only those in staff model HMOs were found to have significantly lower net incomes than their fee-for-service group practice counterparts. Accordingly, there is little evidence to support the popular belief that physicians practicing in HMOs consistently earn less than their fee-for-service counterparts. (Am J Public Health 1983; 73:379-383.)     

Higher fees paid to US physicians drive higher spending for physician services compared to other countries

Higher health care prices in the United States are a key reason that the nation's health spending is so much higher than that of other countries. Our study compared physicians' fees paid by public and private payers for primary care office visits and hip replacements in Australia, Canada, France, Germany, the United Kingdom, and the United States. We also compared physicians' incomes net of practice expenses, differences in financing the cost of medical education, and the relative contribution of payments per physician and of physician supply in the countries' national spending on physician services. Public and private payers paid somewhat higher fees to US primary care physicians for office visits (27 percent more for public, 70 percent more for private) and much higher fees to orthopedic physicians for hip replacements (70 percent more for public, 120 percent more for private) than public and private payers paid these physicians' counterparts in other countries. US primary care and orthopedic physicians also earned higher incomes ($186,582 and $442,450, respectively) than their foreign counterparts. We conclude that the higher fees, rather than factors such as higher practice costs, volume of services, or tuition expenses, were the main drivers of higher US spending, particularly in orthopedics.     

HMO physicians' use of referrals

Clinical uncertainty is a source of variation in medical decision-making as well as a source of work-related stress. Increasing enrollment in organized health care systems has intensified interest in understanding referral utilization as well as issues such as physician dissatisfaction and burnout. We examined whether primary care physicians' affective reactions to uncertainty and their job characteristics were associated with use of referrals and burnout. Data came from mail surveys of primary care physicians practicing in two large group model health maintenance organizations (HMOs) in the USA. Consistent with past research, we found that younger physicians had higher referral rates than older physicians, and that general internists had higher rates than either family practitioners or pediatricians. Greater stress from uncertainty increased referrals and referrals were negatively correlated with heavier work demands (patient visits per hour). Greater stress from uncertainty, perceived workload (too high) and a sense of loss of control over the practice environment were associated with higher levels of burnout.     

Measurement of the primary care roles of office-based physicians.

The Baltimore City Primary Care Study examined the role of the urban office-based physician in the delivery of primary care. During the course of the study, questionnaires were completed by over 90 per cent of licensed physicians in the city, and data were collected from a sample of 16,000 patients. The study developed and assessed three approaches for the measurement of primary care. An empirical method was based upon information regarding the following characteristics of each visit: first contact visit, referral visit, specialized care visit, or principal care visit. A normative method was based on an assessment of the degree to which the practice provided care that was comprehensive, longitudinal, accessible, and family-centered. The third method used physicians' judgments as to the proportion of patients for whom they maintained ongoing responsibility for general medical care. All three methods produced the same categorization of different specialties as providing either primary, intermediate, or specialty care. As a group, primary care physicians included general and family physicians, pediatricians, and general internists. General surgeons and obstetrician/gynecologists have characteristics of both primary care and specialist care. All other physician groups have characteristics of specialists. Any of these methods or a combination of methods can be used to assess the extent to which the practice of a particular physician or group of physicians provides primary care.     

Access to Spanish-speaking physicians in California: supply, insurance, or both

BACKGROUND: National studies report patients with limited English proficiency (LEP) have difficulty finding bilingual physicians; however, it is unclear whether this situation is primarily a result of an inadequate supply of bilingual physicians or a lack of the insurance coverage necessary to gain access to bilingual physicians. In California, 12% of urban residents are Spanish-speaking with some limited proficiency in English. The majority of these residents (67%) are uninsured or on Medicaid. METHODS: In 2001, we performed a mailed survey of a probability sample of primary care and specialist physicians practicing in California. We received 1364 completed questionnaires from 2240 eligible physicians (61%). Physicians were asked about their demographics, practice characteristics, whether they were fluent in Spanish, and whether they had Medicaid or uninsured patients in their practice. RESULTS: Twenty-six percent of primary care and 22% of specialist physicians in the 13 urban study counties reported that they were fluent in Spanish. This represented 146 primary care and 66 specialist physicians who spoke Spanish for every 100,000 Spanish-speaking LEP residents. In contrast to the general population, there were only 48 Spanish-speaking primary care and 29 specialist physician equivalents available for every 100,000 Spanish-speaking LEP patients on Medicaid and even fewer (34 primary care and 4 specialist) Spanish-speaking physician equivalents for every 100,000 Spanish-speaking physician equivalents for uninsured Spanish-speaking LEP patients. CONCLUSION: Although the supply of Spanish-speaking physicians in California is relatively high, the insurance status of LEP Spanish-speaking patients limits their access to the physicians. Addressing health insurance-related barriers to care for those on Medicaid and the uninsured is critical to improving health care for Spanish-speaking LEP patients.     

Medical school type and physician income

We wanted to determine whether the type of medical school attended--private US, public US, or foreign medical school--is associated with practice characteristics or incomes of physicians. Therefore, we used survey responses obtained during the 1990s from 10,436 actively practicing white male physicians who worked in one of 13 medical specialties and who graduated from a public US (5,702), private US (3,797), or international (937) medical school. We used linear regression modeling to determine the association between type of medical school attended and physicians' annual incomes after controlling for specialty, work hours, provider characteristics, and practice characteristics. We found that, for most specialties, international medical school graduates worked longer hours, were less likely to be board certified, had practiced medicine for fewer years, and were less likely to work in rural settings than US medical school graduates. After controlling for key variables, international medical school graduates' annual incomes were 2.6 percent higher (95% CI: 0.1%, 4.4%, p = .043) and public US medical school graduates' were 2.2 percent higher (95% CI: -0.9% -6.1%, p = 0.2) than private US medical school graduates' incomes. Because of their lower tuition expenses, international and public US medical school graduates may experience higher returns on educational investment than their counterparts who graduated from private US medical schools.     

The Rural Physician Workforce in Florida: A Survey of US- and Foreign-Born Primary Care Physicians

CONTEXT: To meet the challenge of primary care needs in rural areas, continuing assessment of the demographics, training, and future work plans of practicing primary care physicians is needed. PURPOSE: This study's goal was to assess key characteristics of primary care physicians practicing in rural, suburban, and urban communities in Florida. METHODS: Surveys were mailed to all of Florida's rural primary care physicians (n = 399) and a 10% sampling (n = 1236) of urban and suburban primary care physicians. FINDINGS: Responses from 1000 physicians (272 rural, 385 urban, 343 suburban) showed that rural physicians were more likely to have been raised in a rural area, foreign-born and trained, a National Health Service Corps member, or a J-1 visa waiver program participant. Rural physicians were more likely to have been exposed to rural medical practice or living in a rural environment during their medical school and residency training. Factors such as rural upbringing and medical school training did not predict future rural practice with foreign-born physicians. Overall, future plans for practice did not seem to differ between rural, urban, and suburban physicians. CONCLUSIONS: Recruiting and retaining doctors in rural areas can be best supported through a mission-driven selection of medical students with subsequent training in medical school and residency in rural health issues. National programs such as the National Health Service Corps and the J-1 visa waiver program also play important roles in rural physician selection and should be taken into account when planning for future rural health care needs.     

Breast cancer screening: effect of physician specialty, practice setting, year of medical school graduation, and sex.

We surveyed physicians of different specialties in a large metropolitan area to determine how their characteristics affected their performance and beliefs about breast cancer screening. Of 664 general internists, obstetrician-gynecologists, and cardiologists surveyed, we received 298 responses (45%). We found significant differences in reported performance of breast cancer screening and physicians' beliefs about mammography screening among practicing obstetrician-gynecologists, internists, and cardiopulmonary specialists. Cardiopulmonary specialists performed the fewest breast examinations and screening mammograms and were most likely to believe annual mammography screening unnecessary even for women in their 50s. We observed no difference between physicians graduating before 1960 and those graduating afterward and no differences according to physician sex. We found similar screening practices and beliefs in the three types of practice settings examined: community-based, private practices, a large health maintenance organization (HMO), and academic medical centers. Obstetrician-gynecologists and internists differed only in the frequency with which they performed breast examinations. Physicians graduating before 1960 in these two groups reported somewhat poorer performance and knowledge of breast cancer screening than those graduating more recently. A majority of all respondents disagreed with American Cancer Society guidelines for mammography screening. Physicians of all specialties reported performing far more breast examinations than screening mammograms on women of all ages, even for those 50-59 years of age. We conclude that all physicians need to improve their screening rates. However, intervention programs should first target those physicians with the greatest deficiencies in breast cancer screening performance and knowledge; these include medical specialists and older physicians in primary care specialties.     

Effects of changes in incomes and practice circumstances on physicians' decisions to treat charity and Medicaid patients

CONTEXT: The decline over the past decade in the percentage of physicians providing care to charity and Medicaid patients has been attributed to both financial pressure and the changing practice environment. Policymakers should be concerned about these trends, since private physicians are a major source of medical care for low-income persons. This study examines how changes in physicians' practice income, ownership, and size affect their decisions to stop or start treating charity care and Medicaid patients. METHODS: This study uses panel data from four rounds of the Community Tracking Study Physician Survey. The dependent variables are the likelihood of physicians' (1) dropping charity care, (2) starting to provide charity care, (3) no longer accepting new Medicaid patients, and (4) starting to accept new Medicaid patients. The primary independent variables are changes in physicians' practice income, ownership, and practice type/size. Multivariate analysis controls for the effects of other physician practice characteristics, health policies, and health care market factors. FINDINGS: A decline in physicians' income increased the likelihood that a physician would stop accepting new Medicaid patients but had no effect on his or her decision to provide charity care. Those physicians who switched from being owners to employees or from small to larger practices were more likely to drop charity care and to start accepting Medicaid patients, and physicians who made the opposite practice changes did the reverse. CONCLUSIONS: Changes in their income and practice arrangements make physicians less willing to accept Medicaid and uninsured patients. Moreover, physicians moving into different practice arrangements treat charity and Medicaid patients as substitutes rather than as similar types of patients. To reverse these trends, policymakers should consider raising Medicaid reimbursement rates and subsidizing organizations that encourage private physicians to provide charity care.     

Rural and Urban Physicians' Perceptions Regarding the Role and Practice of the Nurse Practitioner, Physician Assistant, and Certified Nurse Midwife

ABSTRACT: Context: There is a dearth of literature citing the differences in rural and urban physicians' perceptions of the role and practice of nurse practitioners, physician assistants, and certified nurse midwives (nonphysician providers). Purpose: The purpose of this study was to investigate and compare differences, if any, between rural and urban primary care physicians' perceptions of the role and practice of nonphysician providers. Results: Despite a 15.55% response rate using a mail-out survey in South Carolina, data from 681 rural and urban primary care physicians indicated that they perceived that nonphysician providers possess the necessary skills and knowledge to provide primay care to patients, are an asset to a physician's practice, free the physician's time to handle more critically ill patients, and increase revenue for the practice, but increase the risk of patient care mistakes and a physician's time in administrative duties. Urban physicians' mean scores were higher for perceiving that nonphysician providers are able to see as many patients in a given day as a physician but experience impediments in the delivery of patient care. Conclusions: Results will be used to clarify physicians' perceptions regarding the role and practice of nonphysician providers to reduce impediments to patient care access.     

Using a population-based database to explore the inter-specialty differences in physician practice incomes in Taiwan

Gaining an understanding of the distribution of physician incomes between different medical specialties could assist policymakers to predict the future medical manpower supply. The purpose of this study is to examine the differences in medical specialty-specific gross practice incomes between office-based physicians in Taiwan. The primary data source for the study, which includes 7444 office-based physicians, was provided by the Taiwan Department of Health, with the dependent variable of interest to this study being the annual gross income of physician practices, whilst the independent variable is physician specialty. The study controlled for physicians' age, gender, specialty-board status, type of practice, location of clinic and urbanization level of the community in which the practice was located. Multivariate regression analyses were carried out to explore the relationship between physician specialty and gross practice income. This study finds a significant relationship between the annual gross income of physician practices and the physician's medical specialty (P < 0.001). Of all physicians, those specializing in rehabilitation and orthopedics had the highest gross practice incomes; conversely, obstetricians and gynecologists had the lowest gross practice incomes. The regression analyses demonstrated that after adjusting for socio-demographic and professional characteristics, gross practice incomes of physicians were significantly related to their medical specialty. This study concludes that differences in the gross practice incomes of physicians were significantly related to medical specialties. Those physicians specializing in procedure-based specialties, such as rehabilitation and orthopedics, had higher practice incomes than their counterparts in other more diagnosis-oriented specialties such as family practice and pediatrics.     

How Rural Physicians Compare on Cost and Quality Measures for Medicaid Ambulatory Care Episodes

This study compares the costs and quality of episodes of care for two common childhood illnesses, urinary tract infections (UTI) and otitis media (OM), across providers practicing in rural, small town, and urban counties in Alabama in 1992. The data source is Medicaid claims data for children under age 8 who were treated for these conditions. The study found that episodes cared for by rural providers were less expensive than episodes cared for in other locations, both because fewer rural episodes included outpatient facility charges and because fewer ancillary services were provided in rural settings. Researchers also found that, even controlling for physician characteristics and patient demographic and utilization factors, rural episodes were significantly less likely to include two process measures of quality of care: fewer rural UTI episodes included urine cultures, and fewer rural OM episodes included follow-up visits. This study suggest that, as a group, rural physicians may have a favorable cost profile but a potentially unfavorable care content profile, compared with other physicians. Both practice profile data and explicit care recommendations need to be available to physicians so thy can monitor, defend, or alter their clinical practices.     

Physicians'' use of laboratory, radiology, and drugs in a prepaid group practice HMO.

Use by physicians of medical care resources to treat similar patients and morbidities has implications for the efficiency and effectiveness of medical care. This study examined the variation in primary care physicians' use of outpatient laboratory, radiology, drugs, and hospital admissions; the relationships among the uses of these resources by physicians; and uses of these resources by physicians over time. The setting was a large HMO and the physicians were internists (n = 30), pediatricians (n = 20), and obstetrician/gynecologists (n = 17). Resource use was a dollar rate for laboratory, radiology, and drug, and an admission rate per contact for the hospital. The physicians' use rates were derived from the computerized utilization record of a sample of HMO members for 1976-1978. Substantial variation occurred in the rates of use of each resource by physicians in each specialty. The relationships among the resource rates were similar for internists and pediatricians, and were somewhat stronger than expected clinically. There were also substantial consistencies over time in the levels of use of laboratory and drugs by internists and pediatricians. Findings suggest a potential for more judicious use of ambulatory care resources by primary care physicians in this setting.     

Recruitment and Retention of Physicians for Primary Care Research

The primary objective of this report is to examine factors associated with recruitment of physicians in community-based primary care research. Reported results are based on an observational study of physician recruitment efforts undertaken in a randomized controlled trial designed to improve primary care physicians' cancer screening and counseling activities. The Partners for Prevention project was a state-wide randomized controlled trial of primary care physicians selected from the state of Colorado. Two-hundred and ten eligible internal medicine and family medicine practices in both rural and urban community settings of the state of Colorado were selected into this study and a sentinel physician was chosen to represent each practice. Only 6% (13/210) of recruited practices initially declined to participate in the study, but the total refusal rate had reached 30% (59/210) by the time the intervention was implemented five months later. Study participants (n = 136) were younger (mean age 45.7 vs. 50.0, p = 0.008) and more often located in a rural area (46% vs. 31%, p = 0.04) than decliners (n = 59), but there was no association with gender of the physician (87% for females vs. 95% for males, p = 0.13). Participants were more often family practice physicians by training rather than internists (75% vs. 56%, p = 0.008), whereas there was no difference in participation rates by practice type (solo versus group, 60% vs. 64%, p = 0.52). Differences in demographic, geographic, and training characteristics between trial participants and decliners suggest the potential for better targeting of recruitment efforts. Viable strategies for recruiting community-based primary care practices to research studies are proposed.     

Family physician consultation/referral patterns

Family physicians, regardless of training, board certification, or practice setting, more commonly consult or refer to internal medicine subspecialists than to general internists. The primary reason is need for a consultant with technical (procedural) skill. In the case of pediatric referrals, family physicians more commonly refer to general pediatricians than to pediatric subspecialists. Physicians who use pediatric subspecialists more when both are available, however, do so because of the need for a consultant with technical skill. Large numbers of internal medicine and pediatric residents are choosing subspecialties, thereby increasing availability of these subspecialties. At the same time, there is a documented need for an increased number of primary care physicians. Family physicians, general internists, and general pediatricians all need to be trained; however, because the breadth of training of the family physician prepares this practitioner to provide comprehensive primary care in a broad variety of settings, there should be an emphasis on training this specialist.     

Physician management in primary care.

Minimal explicit consensus criteria in the management of patients with four indicator conditions were established by an ad hoc committee of primary care physicians practicing in different locations. These criteria were then applied to the practices of primary care physicians located in a single community by abstracting medical records and obtaining questionnaire data about patients with the indicator conditions. A standardized management score for each physician was used as the dependent variable in stepwise regression analysis with physician/practice and patient/disease characteristics as the candidate independent variables. For all physicians combined, the mean management scores were high, ranging from .78 to .93 for the four conditions. For two of the conditions, care of the normal infant and pregnant woman, the management scores were better for pediatricians and obstetricians respectively than for family physicians. For the other two conditions, adult onset diabetes and congestive heart failure, there were no differences between the management scores of family physicians and internists. Patient/disease characteristics did not contribute significantly to explaining the variation in the standardized management scores.     

Differences in practice income between solo and group practice physicians

An examination of the distribution of physician incomes between different types of practices could help policymakers and researchers alike to gain an understanding of the effects of different organizational characteristics of practices on the practice of medicine as a whole. This study uses a national database to explore the relationships that exist between practice incomes and practice types vis-à-vis the overall size of practices. The primary data source for this study, which includes 7757 office-based physicians, was provided by the Taiwan Department of Health (DOH), with the dependent variable of interest to this study being the annual gross income of physician practices, while the independent variables are physician practice types and the number of physicians within a clinic. Multiple regression analyses were used to model the logarithm of annual physician practice incomes as a linear function of a set of independent variables. Kruskal-Wallis test results revealed the existence of significant relationships between practice incomes and practice types (p<0.001) and the number of physicians within a clinic (p<0.001). Multiple regression analysis also showed that after adjusting for socio-demographic and professional characteristics, the annual incomes of physicians in both single-specialty or multi-specialty group practices (p<0.001) were higher than those of their solo practice counterparts. This study concludes that after adjusting for other factors, higher practice incomes are enjoyed by physicians in single-specialty or multi-specialty group practices as compared to their solo practice counterparts. The finding of higher incomes for those physicians organized into groups supports the policy call from the DOH in Taiwan for the widespread formation of group practices.     

Medicare payment changes and physicians' incomes

An effort to control the physician portion of Medicare expenditures and to narrow the income gap between primary care and procedure-based physicians was effected through t he enactment of the Medicare Fee Schedule (MFS). To determine whether academic and private sector physicians' incomes had demonstrated changes consistent with payment changes, we collected income information from surveys of private sector physicians and academic physicians in six specialties: (1) family practice; (2) general internal medicine; (3) psychiatry; (4) general surgery; (5) radiology; and (6) anesthesiology. With the exception of general internal medicine, the anticipated changes in Medicare revenue were not closely associated with income changes in either the academic or private sector group. Academic physicians were underpaid, relative to their private sector counterparts, but modestly less so at the end of the period examined. Our findings suggest that using changes in payment schedules to change incomes in order to influence the attractiveness of different specialties, even with a very large payer, may be ineffective. Should academic incomes remain uncompetitive with private sector incomes, it may be increasingly difficult to persuade physicians to enter academic careers.
