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.

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.

The changing geography of Americans graduating from foreign medical schools.

PURPOSE: To study U.S.-born international medical graduates in order to analyze changes in their numbers and countries of training from the 1960s and before until the early 2000s. METHOD: This study was conducted from 2003-2004 at the Center for Health Workforce Studies, University of Washington. The analysis was based on data from March 2002 from the American Medical Association (AMA) for active physicians. AMA data were supplemented with data from several other sources. Descriptive statistics were produced on country of birth, country of medical school training, and year of training for all foreign-trained, patient-care physicians whose birth country was known. RESULTS: At least 17,000 of the foreign-trained physicians practicing in the United States are known to have been born in the United States. American physicians have graduated from foreign medical schools in increasing numbers since the 1960s. The number of U.S.-born physicians who graduated from a foreign medical school peaked in the early 1980s, but the phenomenon endures today. However, the countries in which these physicians chose to attend medical schools have changed significantly from the 1950s to the early 2000s. CONCLUSIONS: Over time, U.S.-born physicians have become much less likely to train in Europe and much more likely to train in certain Caribbean countries. U.S.-born physicians who graduate from medical schools abroad tend to train in just a handful of countries and attend a limited number of medical schools.

Modeling the mental health workforce in Washington State: using state licensing data to examine provider supply in rural and urban areas.

CONTEXT: Ensuring an adequate mental health provider supply in rural and urban areas requires accessible methods of identifying provider types, practice locations, and practice productivity. PURPOSE: To identify mental health shortage areas using existing licensing and survey data. METHODS: The 1998-1999 Washington State Department of Health files on credentialed health professionals linked with results of a licensure renewal survey, 1990 US Census data, and the results of the 1990-1992 National Comorbidity Survey were used to calculate supply and requirements for mental health services in 2 types of geographic units in Washington state-61 rural and urban core health service areas and 13 larger mental health regions. Both the number of 9 types of mental health professionals and their full-time equivalents (FTEs) per 100,000 population measured supply in the health service areas and mental health regions. FINDINGS: Notable shortages of mental health providers existed throughout the state, especially in rural areas. Urban areas had 3 times the psychiatrist FTEs per 100,000 and more than 1.5 times the nonpsychiatrist mental health provider FTEs per 100,000 as rural areas. More than 80% of rural health service areas had at least 10% fewer psychiatrist FTEs and nonpsychiatrist mental health provider FTEs than the state ratio (10.4 FTEs per 100,000 and 306.5 FTEs per 100,000, respectively). Ten of the 13 mental health regions were more than 10% below the state ratio of psychiatrist FTEs per 100,000. CONCLUSIONS: States gathering a minimum database at licensure renewal can identify area-specific mental health care shortages for use in program planning.

Prevalence and trends in smoking: a national rural study.

CONTEXT: Cigarette smoking is the leading preventable cause of death in the United States. PURPOSE: To estimate the prevalence of and recent trends in smoking among adults by type of rural location and by state. METHODS: Random-digit telephone survey of adults aged 18 years or older who participated in the Behavioral Risk Factor Surveillance System in 1994-1996 (n = 342,055) and 2000-2001 (n = 385,384). The main outcome measure was current cigarette smoking, defined as persons who smoke every day or some days, while nonsmokers were those who smoke not at all or reported never having smoked as many as 100 cigarettes. FINDINGS: The prevalence of smoking changed little from the mid-1990s; in 2000-2001, it was 22.0% in urban areas, 24.9% in rural adjacent areas, 24.0% in large rural nonadjacent areas, and 24.9% in small rural nonadjacent areas. For rural locations combined, smoking prevalence was not below the 12% goal of Healthy People 2010 for any state, although the 12.5% prevalence in rural Utah approached this target. Prevalence was > or = 28% for rural residents of Kentucky, Ohio, and Indiana. Since the mid-1990s, the prevalence of smoking for rural respondents decreased by more than 2 percentage points in 6 states: California, Connecticut, Maryland, North Carolina, Tennessee, and Utah. However, it increased by 2 percentage points or more in 10 states: Alabama, Delaware, Georgia, Massachusetts, Michigan, Mississippi, New Hampshire, Oklahoma, South Carolina, and Texas. CONCLUSIONS: Smoking remains a refractory public health problem. Better ways to curb smoking in rural America are needed.

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.

Characterizing the general surgery workforce in rural America.

BACKGROUND: General surgeons form a crucial component of the medical workforce in rural areas of the United States. Any decline in their numbers could have profound effects on access to adequate health care in such areas. HYPOTHESIS: We hypothesize that the rural areas of the United States are relatively undersupplied with general surgeons. DESIGN AND SETTING: The American Medical Association's Physician Masterfile was used to identify all clinically active general surgeons as well as their locations and characteristics. Their geographic distribution was examined using the ZIP code version of the Rural-Urban Commuting Areas. Surgeons were classified as practicing in urban areas, large rural areas, or small/isolated rural areas. RESULTS: There are currently 17 243 general surgeons practicing in the United States. Nationally, the number of general surgeons per population of 100 000 varies from 6.53 in urban areas to 7.71 in large rural areas and 4.67 in small/isolated rural areas. Only 10.6% of the nation's general surgeons are female. Wide variations in numbers of general surgeons were found between and within individual states. General surgeons in the smallest rural areas are more likely than those in urban areas to be male (92.7% vs 88.3%, P<.001), 50 years of age or older (51.6% vs 42.1%, P<.001), or international medical graduates (25.2% vs 20.1%, P<.001). CONCLUSIONS: The overall size of the rural general surgical workforce has remained static over the last decade, but its demographic characteristics suggest that numbers will decline. Many rural residents have limited access to surgical services. Steps to reverse this trend are needed to preserve the viability of health care in many parts of rural America.

The flight of physicians from West Africa: views of African physicians and implications for policy.

West African-trained physicians have been migrating from the sub-continent to rich countries, primarily the US and the UK, since medical education began in Nigeria and Ghana in the 1960s. In 2003, we visited six medical schools in West Africa to investigate the magnitude, causes and consequences of the migration. We conducted interviews and focus groups with faculty, administrators (deans and provosts), students and post-graduate residents in six medical schools in Ghana and Nigeria. In addition to the migration push and pull factors documented in previous literature, we learned that there is now a well-developed culture of medical migration. This culture is firmly rooted, and does not simply fail to discourage medical migration but actually encourages it. Medical school faculty are role models for the benefits of migration (and subsequent return), and they are proud of their students who successfully emigrate.

Trends in professional advice to lose weight among obese adults, 1994 to 2000.

CONTEXT: Obesity is a fast-growing threat to public health in the U.S., but information on trends in professional advice to lose weight is limited. OBJECTIVE: We studied whether rising obesity prevalence in the U.S. was accompanied by an increasing trend in professional advice to lose weight among obese adults. DESIGN AND PARTICIPANTS: We used the Behavioral Risk Factor Surveillance System, a cross-sectional prevalence study, from 1994 (n = 10,705), 1996 (n = 13,800), 1998 (n = 18,816), and 2000 (n = 26,454) to examine changes in advice reported by obese adults seen for primary care. MEASUREMENTS: Self-reported advice from a health care professional to lose weight. RESULTS: From 1994 to 2000, the proportion of obese persons receiving advice to lose weight fell from 44.0% to 40.0%. Among obese persons not graduating from high school, advice declined from 41.4% to 31.8%; and for those with annual household incomes below 25,000 dollars, advice dropped from 44.3% to 38.1%. In contrast, the prevalence of advice among obese persons with a college degree or in the highest income group remained relatively stable and high (> 45%) over the study period. CONCLUSIONS: Disparities in professional advice to lose weight associated with income and educational attainment increased from 1994 to 2000. There is a need for mechanisms that allow health care professionals to devote sufficient attention to weight control and to link with evidence-based weight loss interventions, especially those that target groups most at risk for obesity.

A national study of obesity prevalence and trends by type of rural county.

CONTEXT: Obesity is epidemic in the United States, but information on this trend by type of rural locale is limited. PURPOSE: To estimate the prevalence of and recent trends in obesity among US adults residing in rural locations. METHODS: Analysis of data from the Behavioral Risk Factor Surveillance System (BRFSS) for the years 1994-1996 (n = 342,055) and 2000-2001 (n = 385,384). The main outcome measure was obesity (body mass index [BMI] > or = 30), as determined by calculating BMI from respondents' self-reported height and weight. RESULTS: In 2000-2001, the prevalence of obesity was 23.0% (95% confidence interval [CI] 22.6%-23.4%) for rural adults and 20.5% (95% CI 20.2%-20.7%) for their urban counterparts, representing increases of 4.8% (95% CI 4.2%-5.3%) and 5.5% (95% CI 5.1%-5.9%), respectively, since 1994-1996. The highest obesity prevalence occurred in rural counties in Louisiana, Mississippi, and Texas; obesity prevalence increased for rural residents in all states but Florida over the study period. African Americans had the highest obesity prevalence of any group, up to 31.4% (95% CI 29.1%-33.6) in rural counties adjacent to urban counties. The largest difference in obesity prevalence between those with a college education compared with those without a high school diploma occurred in urban areas (18.4% [95% CI 17.9%-18.9%] vs 23.5% [95% CI 22.5%-24.5%], respectively); the smallest difference occurred in small, remote rural counties (20.3% [95% CI 18.7%-21.9%] versus 22.3% [95% CI 20.7%-24.0%], respectively). CONCLUSIONS: The prevalence of obesity is higher in rural counties than in urban counties; obesity affects some residents of rural counties disproportionately.

Rural definitions for health policy and research.

The term "rural" suggests many things to many people, such as agricultural landscapes, isolation, small towns, and low population density.However, defining "rural" for health policy and research purposes requires researchers and policy analysts to specify which aspects of rurality are most relevant to the topic at hand and then select an appropriate definition. Rural and urban taxonomies often do not discuss important demographic, cultural, and economic differences across rural places-differences that have major implications for policy and research. Factors such as geographic scale and region also must be considered. Several useful rural taxonomies are discussed and compared in this article. Careful attention to the definition of "rural" is required for effectively targeting policy and research aimed at improving the health of rural Americans.

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 23% of 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 6% of the physicians practicing in sub-Saharan Africa now. Nearly 86% of these Africans practicing in the USA originate from only three countries: Nigeria, South Africa and Ghana. Furthermore, 79% were 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.

The productivity of Washington State's obstetrician-gynecologist workforce: does gender make a difference?

OBJECTIVE: To compare the practice productivity of female and male obstetrician-gynecologists in Washington State. METHODS: The primary data collection tool was a practice survey that accompanied each licensed practitioner's license renewal in 1998-1999. Washington State birth certificate data were linked with the licensure data to obtain objective information regarding obstetric births. RESULTS: Of the 541 obstetrician-gynecologists identified, two thirds were men and one third were women. Women were significantly younger than men (mean age 43.3 years versus 51.7 years). Ten practice variables were evaluated: total weeks worked per year, total professional hours per week, direct patient care hours per week, nondirect patient care hours per week, outpatient visits per week, inpatient visits per week, percent practicing obstetrics, number of obstetrical deliveries per year, percentage working less than 32 hours per week, and percentage working 60 or more hours per week. Of these, only 2 variables showed significant differences: inpatient visits per week (women 10.1 per week, men 12.8 per week, P < or =.01) and working 60 or more hours per week (women 22.1% versus men 31.5%, P < or =.05). After controlling for age, analysis of covariance and multiple logistic regression confirmed these findings and in addition showed that women worked 4.1 fewer hours per week than men (P <.01). When examining the ratio of female-to-male practice productivity in 10-year age increments from the 30-39 through the 50-59 age groups, a pattern emerged suggesting lower productivity in many variables in the women in the 40-49 age group. CONCLUSION: Only small differences in practice productivity between men and women were demonstrated in a survey of nearly all obstetrician-gynecologists in Washington State. Changing demographics and behaviors of the obstetrician-gynecologist workforce will require ongoing longitudinal studies to confirm these findings and determine whether they are generalizable to the rest of the United States.

The role of international medical graduates in America's small rural critical access hospitals.

CONTEXT: Critical access hospitals (CAHs) are a federal Medicare category for isolated rural facilities with 15 or fewer acute care beds that receive cost-based reimbursement from Medicare. PURPOSE: This study examines the role of foreign-born international medical graduates (IMGs) in the staffing of CAHs. METHODS: Chief executive officers (CEOs) of CAH facilities answered a telephone survey on their use of IMGs and the characteristics of those IMGs in winter 2002 (388 responded, for a 96% response rate). This descriptive report presents roles and characteristics of IMGs in CAH facilities and the opinions of the CEOs about these practitioners. FINDINGS: Overall, 1 (24%) in 4 admitting physicians in CAHs are graduates of non-US medical schools (compared with 23% of physicians nationally), although the rates are higher for CAHs in persistent poverty counties, CAHs that report recruitment problems, and CAHs with smaller medical staffs. Hospitals east of the Mississippi River are more heavily reliant on IMGs than hospitals in the west. Most IMGs are internists (59%) and most (61%) come from India, the Philippines, or Pakistan. Hospital administrators rate the clinical skills of their IMGs highly and their interpersonal skills only slightly lower. Almost half of CAH administrators said their communities recruited their first IMGs during or after 1994, the year of pro-IMG legislative changes. CONCLUSION: IMG physicians play a significant and possibly growing role in staffing CAHs.

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

CONTEXT: Acute myocardial infarction (AMI) is a common and important cause of admission to US rural hospitals, as transport of patients with AMI to urban settings can result in unacceptable delays in care. PURPOSE: To examine the quality of care for patients with AMI in rural hospitals with differing degrees of remoteness from urban centers. METHODS: This cohort study used data from the Cooperative Cardiovascular Project (CCP), including 4,085 acute care hospitals (408 remote small rural, 893 small rural, 619 large rural, and 2,165 urban) with 135,759 direct admissions of Medicare beneficiaries ages 65 and older for a confirmed AMI between February 1994 and July 1995. Outcomes included use of aspirin, reperfusion, heparin, and intravenous nitroglycerin during hospitalization; use of beta-blockers, aspirin, and angiotensin-converting enzyme (ACE) inhibitors at discharge; avoidance of calcium channel blockers at discharge; and 30-day mortality. FINDINGS: Substantial proportions of Medicare beneficiaries in both urban and rural hospitals did not receive the recommended treatments for AMI. Medicare patients in rural hospitals were less likely than urban hospitals' patients to receive aspirin, intravenous nitroglycerin, heparin, and either thrombolytics or percutaneous transluminal coronary angioplasty. Only ACE inhibitors at discharge was used more for patients in rural hospitals than urban hospitals. Medicare patients in rural hospitals had higher adjusted 30-day post-AMI death rates from all causes than those in urban hospitals (odds ratio for large rural 1.14 [1.10 to 1.18], small rural 1.24 [1.20 to 1.29], remote small rural 1.32 [1.23 to 1.41]). CONCLUSIONS: Efforts are needed to help hospital medical staffs in both rural and urban areas develop systems to ensure that patients receive recommended treatments for AMI.

An analysis of Medicare's Incentive Payment program for physicians in health professional shortage areas.

CONTEXT: Medicare's Incentive Payment (MIP) program provides a 10% bonus payment to providers who treat Medicare patients in rural and urban areas where there is a shortage of generalist physicians. PURPOSE: To examine the experience of Alaska, Idaho, North Carolina, South Carolina, and Washington with the MIP program. We determined the program's utilization and which types of physicians received payments. METHODS: Retrospective cohort design, utilizing complete 1998 Medicare Part B data. Physician specialty was determined through American Medical Association data. Rural status was determined by linking the physician business ZIP code to its Rural-Urban Commuting Area code (RUCA). FINDINGS: There were 2,220,275 patients and 39,749 providers in the cohort, including 9,769 (24.6%) generalists, 21,331 (53.7%) specialists, and 8,649 (21.8%) nonphysician providers. Over $4 million in bonus payments (median payment = $173) were made to providers in HPSAs. Specialists and urban providers received 58% and 14% of the bonus reimbursements, respectively. Two million dollars in payments were not distributed because the providers did not claim them. Over $2.8 million in bonus claims were distributed to providers who likely did not work in approved HPSA sites. CONCLUSIONS: The MIP bonus payments given to providers are small. Many providers who should have claimed the bonus did not, and many providers who likely did not qualify for the bonus claimed and received it. Consideration should be given to focusing and enlarging the bonus payments to specific providers, rather than rewarding all providers equally. Policy makers should also consider a system that prospectively determines provider eligibility.
