Osteopathic physicians and international medical graduates in the rural primary care physician workforce.

BACKGROUND AND OBJECTIVES: Primary care physician (PCP) shortages are a longstanding problem in the rural United States. This study describes the 2005 supply of two important components of the rural PCP workforce: rural osteopathic (DO) and international medical graduate (IMG) PCPs. METHODS: American Medical Association (AMA) and American Osteopathic Association (AOA) 2005 Masterfiles were combined to identify clinically active, non-resident, non-federal physicians aged 70 or younger. Rural-Urban Commuting Area codes were used to categorize practice locations as urban, large rural, small rural, or isolated small rural. National- and state-level analyses were performed. PCPs included family physicians, general internists, and general pediatricians. RESULTS: DOs comprised 4.9% and IMGs 22.2% of the total clinically active workforce. However, they contributed 10.4% and 19.3%, respectively, to the rural PCP workforce, although their relative representation varied geographically. DO PCPs were more likely than allopathic PCPs to practice in rural places (20.5% versus 14.9%, respectively). IMG PCPs were more likely than other PCPs to practice in rural persistent poverty locations (12.4% versus 9.1%). The proportion of rural PCP workforce represented by DOs increased with increasing rurality and that of IMGs decreased. CONCLUSIONS: DO and IMG PCPs constitute a vital portion of the rural health care workforce. Their ongoing participation is necessary in addressing existing rural PCP shortages and handling the influx of newly insured residents as the Patient Protection and Affordable Care Act (ACA) comes into effect. The impact on rural DO and IMG PCP supply of ACA measures intended to increase their numbers remains to be seen.

The characteristics of registered nurses whose licenses expire: why they leave nursing and implications for retention and re-entry.

Little is known about RNs who drop their licenses and their potential re-entry into the nursing workforce. The results of this study provide insight into reasons nurses leave their careers and the barriers to re-entry, all important indicators of the current professional climate for nursing. While representing only one state, these findings suggest that RNs who allow their licenses to expire do so because they have reached retirement age or, among those who do not cite age as a factor, because many are unable or unwilling to work in the field. Inactive nurses who might otherwise appear to be likely candidates for re-entry into the profession may not be easily encouraged to practice nursing again without significant changes in their personal circumstances or the health care work environment. Effective ways to address current and pending RN workforce shortages include expanding RN education capacity to produce more RNs who can contribute to the workforce across the coming decades, and promote work environments in which RNs want to, and are able to, practice across a long nursing career.

Geographic differences in use of home oxygen for obstructive lung disease: a national Medicare study.

RATIONALE: Home oxygen is the most expensive equipment item that Medicare purchases ($1.7 billion/year). OBJECTIVES: To assess geographic differences in supplemental oxygen use. METHODS: Retrospective cohort analysis of oxygen claims for a 20% random sample of Medicare patients hospitalized for obstructive lung disease in 1999 and alive at the end of 2000. MEASUREMENTS AND MAIN RESULTS: While 33.7% of the 34,916 hospitalized patients used supplemental oxygen, there was more than a 4-fold difference between states and a greater than 6-fold difference between hospital referral regions with high/low utilization. Rocky Mountain States and Alaska had the highest utilization, while the District of Columbia and Louisiana had the lowest utilization. After adjusting for patient characteristics and elevation, high-utilization communities included low-lying areas in California, Florida, Michigan, Missouri, and Washington. Patients who were younger, male, white, and who had more comorbidities, more hospital admissions, and lived at higher altitudes and in areas of greater income also had higher odds of using supplemental oxygen. Residing in rural areas was associated with higher unadjusted oxygen use rates. After adjustment, patients living in large rural areas had higher odds of using oxygen than patients living in urban areas or in small rural areas. CONCLUSIONS: There is significant geographic variation in supplemental oxygen use, even after controlling for patient and contextual factors. The Centers for Medicare & Medicaid Services should examine these issues further and enact changes that ensure patient health and fiscal responsibility.

Which medical schools produce rural physicians? A 15-year update.

PURPOSE: Despite continued federal and state efforts to increase the number of physicians in rural areas, disparities between the supply of rural and urban physicians persist. The authors examined the training of the rural physician workforce in the United States. METHOD: Using a national cross-sectional analysis of the 2005 American Medical Association and American Osteopathic Association Masterfile physician data, the authors examined a 10-year cohort of clinically active MD and DO physicians who graduated from medical school between 1988 and 1997. RESULTS: Eleven percent (20,037) of the physician cohort were currently practicing in a rural location in 2005. Eighteen percent (2,045) of osteopathic medical school graduates were currently practicing in a rural location. Twenty-three percent (6,282) of family physician graduates practiced in rural areas. Women continue to be less likely than men to practice in rural areas, although the gap is narrowing. Rural residency trainees were over three times more likely to practice in rural areas (RR = 3.4, P < .001). CONCLUSIONS: The proportion and number of physicians entering rural practice has remained stable compared with earlier analyses. However, recent trends such as declining primary care interest are not yet reflected in these data and may portend worsening shortages of rural physicians.

Quality of care for myocardial infarction in rural and urban hospitals.

BACKGROUND: In the mid-1990s, significant gaps existed in the quality of acute myocardial infarction (AMI) care between rural and urban hospitals. Since then, overall AMI care quality has improved. This study uses more recent data to determine whether rural-urban AMI quality gaps have persisted. METHODS: Using inpatient records data for 34,776 Medicare beneficiaries with AMI from 2000-2001, unadjusted and logistic regression analysis compared receipt of 5 recommended treatments between admissions to urban, large rural, small rural, and isolated small rural hospitals as defined by Rural Urban Commuting Area codes. RESULTS: Substantial proportions of hospital admissions in all areas did not receive guideline-recommended treatments (eg, 17.0% to 23.6% without aspirin within 24 hours of admission, 30.8% to 46.6% without beta-blockers at arrival/discharge). Admissions to small rural and isolated small rural hospitals were least likely to receive most treatments (eg, 69.2% urban, 68.3% large rural, 59.9% small rural, 53.4% isolated small rural received discharge beta-blocker prescriptions). Adjusted analyses found no treatment differences between admissions to large rural and urban area hospitals, but admissions to small rural and isolated small rural hospitals had lower rates of discharge prescriptions such as aspirin and beta-blockers than urban hospital admissions. CONCLUSIONS: Many simple guidelines that improve AMI outcomes are inadequately implemented, regardless of geographic location. In small rural and isolated small rural hospitals, addressing barriers to prescription of beneficial discharge medications is particularly important. The best quality improvement practices should be identified and translated to the broadest range of institutions and providers.

Do international medical graduates (IMGs) "fill the gap" in rural primary care in the United States? A national study.

CONTEXT: The contribution that international medical graduates (IMGs) make to reducing the rural-urban maldistribution of physicians in the United States is unclear. Quantifying the extent of such "gap filling" has significant implications for planning IMG workforce needs as well as other state and federal initiatives to increase the numbers of rural providers. PURPOSE: To compare the practice location of IMGs and US medical graduates (USMGs) practicing in primary care specialties. METHODS: We used the 2002 AMA physician file to determine the practice location of all 205,063 primary care physicians in the United States. Practice locations were linked to the Rural-Urban Commuting Areas, and aggregated into urban, large rural, small rural, and isolated small rural areas. We determined the difference between the percentage of IMGs and percentage of USMGs in each type of geographic area. This was repeated for each Census Division and state. FINDINGS: One quarter (24.8% or 50,804) of primary care physicians in the United States are IMGs. IMGs are significantly more likely to be female (31.9% vs 29.9%, P < .0001), older (mean ages 49.7 and 47.1 year, P < .0001), and less likely to practice family medicine (19.0% vs 38%, P < .0001) than USMGs. We found only two Census Divisions in which IMGs were relatively more likely than USMGs to practice in rural areas (East South Central and West North Central). However, we found 18 states in which IMGs were more likely, and 16 in which they were less likely to practice in rural areas than USMGs. CONCLUSIONS: IMGs fill gaps in the primary care workforce in many rural areas, but this varies widely between states. Policies aimed to redress the rural-urban physician maldistribution in the United States should take into account the vital role of IMGs.

Trends in perinatal and infant health disparities between rural American Indians and Alaska natives and rural Whites.

OBJECTIVES: We examined disparities in perinatal care, birth outcomes, and infant health between rural American Indian and Alaska Native (AIAN) persons and rural Whites over time. METHODS: We compared perinatal and infant health measures for 217 064 rural AIAN births and 5 032 533 rural non-Hispanic White births. RESULTS: Among American Indians and Alaska Natives, unadjusted rates of inadequate prenatal care (1985-1987, 36.3%; 1995-1997, 26.3%) and postneonatal death (1985-1987, 7.1 per 1000; 1995-1997, 4.8 per 1000) improved significantly. However, disparities between American Indians and Alaska Natives and Whites in adjusted odds ratios (AORs) of postneonatal death (1985-1987, AOR = 1.55; 95% confidence interval [CI] = 1.41, 1.71; 1995-1997, AOR = 1.46; 95% CI = 1.31, 1.64) and adjusted risk ratios (ARRs) of inadequate prenatal care (1985-1987, ARR = 1.67; 95% CI = 1.65, 1.69; 1995-1997, ARR = 1.84; 95% CI = 1.81, 1.87) persisted. CONCLUSIONS: Despite significant decreases in inadequate prenatal care and postneonatal death among American Indians and Alaska Natives, additional measures are needed to close persistent health gaps for this group.

Access to cancer services for rural colorectal cancer patients.

CONTEXT: Cancer care requires specialty surgical and medical resources that are less likely to be found in rural areas. PURPOSE: To examine the travel patterns and distances of rural and urban colorectal cancer (CRC) patients to 3 types of specialty cancer care services--surgery, medical oncology consultation, and radiation oncology consultation. METHODS: Descriptive cross-sectional study using linked Surveillance, Epidemiology, and End Results (SEER) cancer registry and Medicare claims data for 27,143 individuals ages 66 and older diagnosed with stages I through III CRC between 1992 and 1996. FINDINGS: Over 90% of rural CRC patients lived within 30 miles of a surgical hospital offering CRC surgery, but less than 50% of CRC patients living in small and isolated small rural areas had a medical or radiation oncologist within 30 miles. Rural CRC patients who traveled outside their geographic areas for their cancer care often went great distances. The median distance traveled by rural cancer patients who traveled to urban cancer care providers was 47.8 miles or more. A substantial proportion (between 19.4% and 26.0%) of all rural patients bypassed their closest medical and radiation oncology services by at least 30 miles. CONCLUSIONS: Rural CRC patients often travel long distances for their CRC care, with potential associated burdens of time, cost, and discomfort. Better understanding of whether this travel investment is paid off in improved quality of care would help rural cancer patients, most of whom are elderly, make informed decisions about how to use their resources during their cancer treatment.

Access to specialty health care for rural American Indians in two states.

CONTEXT: The Indian Health Service (IHS), whose per capita expenditure for American Indian and Alaska Native (AI/AN) health services is about half that of the US civilian population, is the only source of health care funding for many rural AI/ANs. Specialty services, largely funded through contracts with outside practitioners, may be limited by low IHS funding levels. PURPOSE: To examine specialty service access among rural Indian populations in two states. METHODS: A 31-item mail survey addressing perceived access to specialty physicians, barriers to access, and access to non-physician clinical services was sent to 106 primary care providers in rural Indian health clinics in Montana and New Mexico (overall response rate 60.4%) and 95 primary care providers in rural non-Indian clinics within 25 miles of the Indian clinics (overall response rate 57.9%). FINDINGS: Substantial proportions of rural Indian clinic providers in both states reported fair or poor non-emergent specialty service access for their patients. Montana's rural Indian clinic providers reported poorer patient access to specialty care than rural non-Indian clinic providers, while New Mexico's rural Indian and non-Indian providers reported comparable access. Indian clinic providers in both states most frequently cited financial barriers to specialty care. Indian clinic providers reported better access to most non-physician services than non-Indian clinic providers. CONCLUSIONS: Reported limitations in specialty care access for rural Indian clinic patients appear to be influenced by financial constraints. Health care systems factors may play a role in perceived differences in specialty access between rural Indian and non-Indian clinic patients.

A longitudinal analysis of the general surgery workforce in the United States, 1981-2005.

HYPOTHESIS: The overall supply of general surgeons per 100 000 population has declined in the past 2 decades, and small and isolated rural areas of the United States continue to have relatively fewer general surgeons per 100 000 population than urban areas. DESIGN: Retrospective longitudinal analysis. SETTING: Clinically active general surgeons in the United States. PARTICIPANTS: The American Medical Association's Physician Masterfiles from 1981, 1991, 2001, and 2005 were used to identify all clinically active general surgeons in the United States. MAIN OUTCOME MEASURES: Number of general surgeons per 100 000 population and the age, sex, and locale of these surgeons. RESULTS: General surgeon to population ratios declined steadily across the study period, from 7.68 per 100 000 in 1981 to 5.69 per 100 000 in 2005. The overall urban ratio dropped from 8.04 to 5.85 (-27.24%) across the study period, and the overall rural ratio dropped from 6.36 to 5.02 (-21.07%). The average age of rural surgeons increased compared with their urban counterparts, and women were disproportionately concentrated in urban areas. CONCLUSIONS: The overall number of general surgeons per 100 000 population has declined by 25.91% during the past 25 years. The decline has been most marked in urban areas. However, more remote rural areas continue to have significantly fewer general surgeons per 100 000 population. These findings have implications for training, recruiting, and retaining general surgeons.

Growth and change in the physician assistant workforce in the United States, 1967-2000.

The physician assistant (PA) profession grew rapidly in the 1970s and 1990s. As acceptance of PAs in the health care system increased, roles for PAs in specialty care took shape and the scope of PA practice became more clearly defined. This report describes key elements of change in the demography and distribution of the PA population between 1967 and 2000, as well as the spread of PA training programs. Individual-level data from the American Academy of Physician Assistants, supplemented with county-level aggregate data from the Area Resource File, were used to describe the emergence of the PA profession between 1967 and 2000. Data on 49,641 PAs who had completed training by 2000 were analyzed. More than half (52.4%) of PAs active in 2000 were women. PA participation in the rural workforce remains high, with more than 18% of PAs practicing in rural settings, compared with about 20% in 1980. Primary care participation appears to have stabilized at about 47% among active PAs for whom specialty is known. By 2000, 51.5% of practicing PAs had been trained in the states where they worked. The profession has grown rapidly; 56% of all PAs were trained between 1991 and 2000. In 2000, more than 42% of accredited PA programs offered a master's degree, compared to master's degree programs in 1986. Although many critical issues of scope of practice and patient and physician acceptance of PAs have been resolved, the PA profession remains young and continues to evolve. Whether the historical contribution of PAs to primary care for rural and underserved populations can be sustained in the face of increasing specialization and higher-level academic credentialing is not clear.

Measuring participant rurality in Web-based interventions.

BACKGROUND: Web-based health behavior change programs can reach large groups of disparate participants and thus they provide promise of becoming important public health tools. Data on participant rurality can complement other demographic measures to deepen our understanding of the success of these programs. Specifically, analysis of participant rurality can inform recruitment and social marketing efforts, and facilitate the targeting and tailoring of program content. Rurality analysis can also help evaluate the effectiveness of interventions across population groupings. METHODS: We describe how the RUCAs (Rural-Urban Commuting Area Codes) methodology can be used to examine results from two Randomized Controlled Trials of Web-based tobacco cessation programs: the ChewFree.com project for smokeless tobacco cessation and the Smokers' Health Improvement Program (SHIP) project for smoking cessation. RESULTS: Using RUCAs methodology helped to highlight the extent to which both Web-based interventions reached a substantial percentage of rural participants. The ChewFree program was found to have more rural participation which is consistent with the greater prevalence of smokeless tobacco use in rural settings as well as ChewFree's multifaceted recruitment program that specifically targeted rural settings. CONCLUSION: Researchers of Web-based health behavior change programs targeted to the US should routinely include RUCAs as a part of analyzing participant demographics. Researchers in other countries should examine rurality indices germane to their country.

International medical graduate physicians in the United States: changes since 1981.

Nearly a quarter of all active U.S. physicians are international medical graduates (IMGs)--physicians trained outside the United States and Canada. We describe changes in characteristics of IMGs from 1981 to 2001 and compare them with their U.S. medical graduate (USMG) counterparts. Since 1981, the leading source countries for IMGs have included India, the Philippines, and Mexico. IMGs were more likely to be generalists and to practice in designated underserved areas than USMGs but slightly less likely to practice in isolated small rural areas and persistent-poverty counties. IMGs are an important source of primary care physicians in rural and underserved areas.

The Washington State Nurse Anesthetist Workforce: a case study.

The purposes of this study were to describe the Washington State Certified Registered Nurse Anesthetist (CRNA) workforce and analyze selected dimensions of their clinical practice. We developed the 31-item CRNA Practice Questionnaire. After receiving institutional review board approval, the questionnaire was mailed in 2003 to CRNAs licensed in Washington with an address in Washington, Oregon, and Idaho. Statistical analysis included descriptive statistics for all variables and was performed by University of Washington Center for Health Workforce Studies staff. Results indicate that the typical Washington State CRNA is 50.7 years old, white, and equally likely to be a man or woman. More than half of the Washington State CRNAs are master's educated and have an average of 19 years of CRNA experience. Most work at least 40 hours a week, take call, and earn more than 100,000 dollars per year. Almost all have hospital privileges, but only 30% believe they are equal colleagues with physicians. A chi2 analysis comparing urban and rural respondents yielded few differences except that rural CRNAs reported seeking significantly less consultation and were more likely to take call. Workforce data may assist CRNAs when negotiating with employers and institutions and in resolving interprofessional conflicts and can have implications for scope of practice, policy, and legislative issues.

Geographic access to health care for rural Medicare beneficiaries.

CONTEXT: Patients in rural areas may use less medical care than those living in urban areas. This could be due to differences in travel distance and time and a utilization of a different mix of generalists and specialists for their care. PURPOSE: To compare the travel times, distances, and physician specialty mix of all Medicare patients living in Alaska, Idaho, North Carolina, South Carolina, and Washington. METHODS: Retrospective design, using 1998 Medicare billing data. Travel time was determined by computing the road distance between 2 population centroids: the patient's and the provider's zone improvement plan codes. FINDINGS: There were 2,220,841 patients and 39,780 providers in the cohort, including 6,405 (16.1%) generalists, 24,772 (62.3%) specialists, and 8,603 (21.6%) nonphysician providers. There were 20,693,828 patient visits during the study. The median overall 1-way travel distance and time was 7.7 miles (interquartile range 1.9-18.7 miles) and 11.7 minutes (interquartile range 3.0-25.7 minutes). The patients in rural areas needed to travel 2 to 3 times farther to see medical and surgical specialists than those living in urban areas. Rural residents with heart disease, cancer, depression, or needing complex cardiac procedures or cancer treatment traveled the farthest. Increasing rurality was also related to decreased visits to specialists and an increasing reliance on generalists. CONCLUSIONS: Residents of rural areas have increased travel distance and time compared to their urban counterparts. This is particularly true for rural residents with specific diagnoses or those undergoing specific procedures. Our results suggest that most rural residents do not rely on urban areas for much of their care.

Characteristics of registered nurses in rural versus urban areas: implications for strategies to alleviate nursing shortages in the United States.

METHODS: This study compares characteristics of rural and urban registered nurses (RNs) in the United States using data from the 2000 National Sample Survey of Registered Nurses. RNs in 3 types of rural areas are examined using the rural-urban commuting area taxonomy. FINDINGS: Rural and urban RNs are similar in age and sex; nonwhites and Hispanics are underrepresented in both groups. Rural RNs have less nursing education, are less likely to work in hospitals, and are more likely to work full time and in public/community health than urban RNs. The more rural an RN's residence, the more likely he/she commutes to another area for work and the lower salary he/she receives. CONCLUSIONS: Strategies to reduce nurse shortages should consider differences in education, work patterns, and commuting behavior among rural and urban RNs. Solutions for rural areas require understanding of the impact of the workplace on these behaviors.

Shortages of medical personnel at community health centers: implications for planned expansion.

CONTEXT: The US government is expanding the capacity of community health centers (CHCs) to provide care to underserved populations. OBJECTIVE: To examine the status of workforce shortages that may limit CHC expansion. DESIGN AND SETTING: Survey questionnaire of all 846 federally funded US CHCs that directly provide clinical services and are within the 50 states and the District of Columbia, conducted between May and September 2004. Questionnaires were completed by the chief executive officer of each grantee. Information was supplemented by data from the 2003 Bureau of Primary Health Care Uniform Data System and weighted to be nationally representative. MAIN OUTCOME MEASURES: Staffing patterns and vacancies for major clinical disciplines by rural and urban location, use of federal and state recruitment programs, and perceived barriers to recruitment. RESULTS: Overall response rate was 79.3%. Primary care physicians made up 89.4% of physicians working in the CHCs, the majority of whom are family physicians. In rural CHCs, 46% of the direct clinical providers of care were nonphysician clinicians compared with 38.9% in urban CHCs. There were 428 vacant funded full-time equivalents (FTEs) for family physicians and 376 vacant FTEs for registered nurses. There were vacancies for 13.3% of family physician positions, 20.8% of obstetrician/gynecologist positions, and 22.6% of psychiatrist positions. Rural CHCs had a higher proportion of vacancies and longer-term vacancies and reported greater difficulty filling positions compared with urban CHCs. Physician recruitment in CHCs was heavily dependent on National Health Service Corps scholarships, loan repayment programs, and international medical graduates with J-1 visa waivers. Major perceived barriers to recruitment included low salaries and, in rural CHCs, cultural isolation, poor-quality schools and housing, and lack of spousal job opportunities. CONCLUSIONS: CHCs face substantial challenges in recruitment of clinical staff, particularly in rural areas. The largest numbers of unfilled positions were for family physicians at a time of declining interest in family medicine among graduating US medical students. The success of the current US national policy to expand CHCs may be challenged by these workforce issues.

Problem drinking: rural and urban trends in America, 1995/1997 to 2003.

OBJECTIVE: Studies examining trends in problem alcohol use for U.S. adults residing in rural locations are lacking. This study examines recent trends in heavy and binge drinking in urban counties and three types of rural counties. METHODS: Random-digit telephone survey of adults aged 18 years or older residing in states participating in the Behavioral Risk Factor Surveillance System, in the years 1995/1997 (n = 247,255), 1999/2001 (n = 362,077) and 2003 (n = 257,659). Analyses were performed in 2006. RESULTS: Metropolitan counties experienced higher prevalence of heavy and binge drinking than rural counties in all years, and all geographic areas showed upward trends in both drinking behaviors. Trends in heavy drinking were sharper in rural counties (3.8% to 5.4% compared with 4.9% to 6.0% in metro counties). Metropolitan and rural counties overall saw similar increases in binge drinking, however, the greatest increase occurred in remote micropolitan counties (12.7% to 15.7%). CONCLUSION: Heavy and binge drinking are problems that continue to increase in rural areas nationwide. Because of the difficulties inherent in accessing and administering substance abuse treatment in rural areas, special attention should be given to tailoring alcohol abuse interventions to the needs of rural residents.
