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.

Obstetric care and payment source: do low-risk Medicaid women get less care?

OBJECTIVES: This study examined whether Medicaid-insured women at low risk receive less adequate obstetrical care than privately insured women. METHODS: Low-risk women who were cared for by a random sample of obstetrical providers in Washington State were randomly selected. Information on all prenatal and intrapartum services was abstracted from medical records. Service information was aggregated into standardized resource-use units. Results compared Medicaid-insured women with those who were privately insured. RESULTS: Medicaid-insured women were significantly younger (22.5 years vs 26.9 years) and averaged 6% fewer visits than privately insured women. Nonetheless, Medicaid status had no meaningful association with prenatal, intrapartum, or overall resource use. Some variation occurred in individual resources received. Medicaid-insured women had 38.8% more resources expended on testing for sexually transmitted diseases. Privately insured women had more resources expended on alpha-fetoprotein testing and on amniocentesis. There were no meaningful differences in birthweight or gestational age at delivery. CONCLUSIONS: In this study of women who entered obstetrical care at low risk, similar care and resources were expended on Medicaid-insured and on privately insured women.

Is non-metropolitan residence a risk factor for poor birth outcome in the U.S.?

The association between non-metropolitan residence and the risk of poor birth outcome in the United States was examined using the records of 11.06 million singleton births in the United States between 1985 and 1987. Rates of neonatal and post-neonatal death, low birth weight and late prenatal care among non-metropolitan residents were compared to the rates among metropolitan residents. The association between residence in a non-metropolitan area and the risk of poor birth outcome was assessed in national and state level regression analyses. Residence in a non-metropolitan county was not found to be associated with increased risk of low birth weight or neonatal mortality at the national level or in most states, after controlling for several demographic and biological risk factors. Non-metropolitan residence was associated with greater risk of post-neonatal mortality at the national level. Non-metropolitan residence was strongly associated with late initiation of prenatal care at both the national level and in a majority of the states. Residence in non-metropolitan areas does not appear to be associated with higher risk of adverse birth outcome. Regionalization of perinatal care and other changes in the rural health care system may have mitigated the risk associated with residing in areas relatively isolated from tertiary care. High levels of late prenatal care among non-metropolitan residents suggest a continuing problem of access to routine care for rural women and their infants that may be associated with higher levels of post-neonatal mortality and childhood morbidity.

Hospital services for rural children in Washington State.

OBJECTIVE: To examine the current delivery of inpatient hospital services to a statewide population of rural children, define the types of pediatric conditions currently treated in rural hospitals or transferred to urban centers, and explore the role of rural pediatricians and family practitioners in the care of children in rural hospitals. DESIGN: Retrospective review of statewide hospital discharge data. SUBJECTS: All patients younger than 18 years of age with nonsurgical diagnoses discharged from both urban and rural civilian hospitals in Washington State during 1989 and 1990. RESULTS: Of 69690 pediatric hospital discharges during the study period, 16% were rural residents and 10% were from rural hospitals. Rural hospitals cared for 59% of hospitalized rural children. Marked differences were found between urban and rural hospitals in the diagnoses treated; more than two-thirds of all discharges for chemotherapy, psychiatric disorders, and neonates with multiple major problems were from urban hospitals; but the majority of the discharges for gastrointestinal diagnoses, respiratory conditions, or minor problems in the neonatal period were from rural hospitals. Rural hospitals with staff pediatricians had higher annual pediatric discharges, total charges, lengths of stay, and case mix with a higher proportion of neonates with complications, compared to hospitals without pediatricians. However, there was no evidence that these hospitals served as local referral centers for rural pediatric inpatients; the proportion of patients from outside the local hospital catchment areas was similar for rural hospitals with staff pediatricians and for those without. In rural hospitals, pediatricians and family practitioners were listed as the attending physician for 37% and 49% of discharges, respectively. The average rural pediatrician cared for five times as many inpatients as a rural family practitioner. Pediatricians cared for significantly more neonates with birth weights of less than 2500 grams, but otherwise had a similar case mix among inpatient discharges as rural family practitioners. CONCLUSIONS: Most rural children in Washington who require hospitalization for common problems receive their care in local rural hospitals staffed with pediatricians and family practitioners, although those with illnesses requiring a high level of specialty care are predominantly cared for in urban centers. Rural pediatricians make a substantial contribution to the care of rural children, especially in the area of neonatal care, although their presence in rural hospitals does not in itself create local referral centers. Inpatient volumes are higher for pediatricians, but their case mix is similar to that of rural family practitioners, except in the area of neonatology. These data support the recommendations that family practitioners contemplating rural practice receive training in general inpatient pediatrics (regardless of whether they are going to a site with pediatricians) and that pediatricians in rural practice be trained for a high volume of inpatient cases, including problems of low birth weight infants. Because systems of hospital care for rural children depend on regionalized programs, clinical and educational linkages between urban centers and rural providers should be developed and supported.

Access to maternity care in rural Washington: its effect on neonatal outcomes and resource use.

OBJECTIVES: This study sought to ascertain the effects of poor local access to obstetric care on the risks of having a neonate diagnosed as non-normal, a long hospital stay, and/or high hospital charges. METHODS: Washington State birth certificates linked with hospital discharge abstracts of mothers and neonates were used to study 29809 births to residents of rural areas. Births to women from rural areas where more than two thirds of the women left for care were compared with births to women from rural areas where fewer than one third left for care. RESULTS: Poor local access to providers of obstetric care was associated with a significantly greater risk of having a non-normal neonate for both Medicaid and privately insured patients. However, poor local access to care was consistently associated with higher charges and increased hospital length of stay only if the patient was privately insured. CONCLUSIONS: These results indicate that local maternity services may help prevent non-normal births to rural women and, among privately insured women, might decrease use of neonatal resources.

Interspecialty differences in the obstetric care of low-risk women.

OBJECTIVES: This study examined differences among obstetricians, family physicians, and certified nurse-midwives in the patterns of obstetric care provided to low-risk patients. METHODS: For a random sample of Washington State obstetrician-gynecologists, family physicians, and certified nurse-midwives, records of a random sample of their low-risk patients beginning care between September 1, 1988, and August 31, 1989, were abstracted. RESULTS: Certified nurse-midwives were less likely to use continuous electronic fetal monitoring and had lower rates of labor induction or augmentation than physicians. Certified nurse-midwives also were less likely than physicians to use epidural anesthesia. The cesarean section rate for patients of certified nurse-midwives was 8.8% vs 13.6% for obstetricians and 15.1% for family physicians. Certified nurse-midwives used 12.2% fewer resources. There was little difference between the practice patterns of obstetricians and family physicians. CONCLUSIONS: The low-risk patients of certified nurse-midwives in Washington State received fewer obstetrical interventions than similar patients cared for by obstetrician-gynecologists or family physicians. These differences are associated with lower cesarean section rates and less resource use.

Rural hospitals' experience with the National Practitioner Data Bank.

OBJECTIVES: This study examined hospital administrators' experiences with the National Practitioner Data Bank. METHODS: One hundred forty-nine rural hospital administrators completed questionnaires assessing their perceptions of the data bank. RESULTS: Nearly 90% of respondents rated the data bank as an important source of information for credentialing. Three percent indicated it had directly affected privileging decisions; 43% and 34%, respectively, believed the costs exceeded or equaled the benefits. Twenty percent reported changes that could decrease disciplinary action reports to the data bank. CONCLUSIONS: While the National Practitioner Data Bank is an important source of information to rural hospitals, it may, affect few credentialing decisions and motivate behavioral changes that could have a paradoxical effect on quality assurance.

The regionalization of perinatal care in Wales and Washington State.

OBJECTIVES: The purpose of this study was to compare perinatal regionalization and neonatal mortality in Wales and Washington State. METHODS: The 28 hospitals in Wales and the 80 hospitals in Washington State that offered maternity services and the 218,326 births that occurred in these hospitals in 1989 and 1990 were studied. Surveys were used to identify the neonatal technology and the referral policies of each hospital, and linked data from birth and death certificates were used to examine birthweight-specific neonatal mortality rates for all babies born in these hospitals. RESULTS: Welsh district general hospitals (broadly equivalent to Level II perinatal centers in the United States) have more sophisticated neonatal technology than their Washington State counterparts and appear less likely to refer small or preterm babies to regional or subregional centers. Neonatal mortality rates were quite similar in the two settings. CONCLUSIONS: Perinatal care in Wales appears to be less regionalized than in a similar region in the United States. The relative lack of perinatal regionalization in Wales may contribute to duplication and underutilization of expensive neonatal technologies. National health care systems do not, in and of themselves, lead to optimal regionalization of services.

Predicting the degree of rurality of physician assistant practice location.

This study used a block multiple regression analysis to examine the impacts of different factors on the degree of rurality of physician assistants' (PAs') practice location and compared the power of each block of factors in predicting rurality. Differences in the models for PAs in primary care specialties and for PAs as a whole were also explored. The findings suggest that policies should provide support to PA students in primary care specialties and to rural-oriented PA education/training programs. Efforts to facilitate PA recruitment and retention should include, among other things, increasing practice responsibility/autonomy, broadening acceptance of PA prescriptive authority, and providing equitable reimbursement for nonphysician care of Medicare and Medicaid beneficiaries.

Rural and urban differences in physician resource use for low-risk obstetrics.

OBJECTIVE: To explore the hypothesis that rural obstetricians (OBs) and family physicians (FPs) utilized fewer resources during the care of the low-risk women who initially booked with them than did their urban counterparts of the same specialties. DATA SOURCES/STUDY DESIGN: A stratified random sample of Washington state rural and urban OBs and FPs was selected during 1989. A participation rate of 89 percent yielded 209 participating physicians. The prenatal and intrapartum medical records of a random sample of the low-risk patients who initiated care with the sampled providers during a one-year period were abstracted in detail and analyzed with the physician as the unit of analysis. Complete data for 1,683 patients were collected. Resource use elements (e.g., urine culture) were combined by standardizing them with average charge data so that aggregate resource use could be analyzed. Intraspecialty comparisons for resource use by category and overall were performed. FINDINGS/CONCLUSIONS: Results show that rural physicians use fewer overall resources in caring for nonreferred low-risk-booking obstetric patients than do their urban colleagues. Resource use unit expenditures showed the hypothesized pattern for both specialties for total, intrapartum, and prenatal care with the exception of FPs for prenatal care. Approximately 80 percent of the resource units used by each physician type were related to hospital care. No differences were shown in patterns of care for most clinically important aspects of care (e.g., cesarean delivery rates), and no evidence suggested that outcomes differed. The overall differences were due to specific components of care (e.g., fewer intrapartum hospital days and less epidural anesthesia).

Physician office visits for low back pain. Frequency, clinical evaluation, and treatment patterns from a U.S. national survey.

STUDY DESIGN: This study is an analysis of national survey data from 5 sample years. OBJECTIVES: The authors characterized the frequency of office visits for low back pain, the content of ambulatory care, and how these vary by physician specialty. SUMMARY OF BACKGROUND DATA: Few recent data are available regarding ambulatory care for low back pain or how case mix and patient management vary by physician specialty. METHODS: Data from the National Ambulatory Medical Care Survey were grouped into three time periods (1980-81, 1985, 1989-90). Frequency of visits for low back pain, referral status, tests, and treatments were tabulated by physician specialty. RESULTS: There were almost 15 million office visits for "mechanical" low back pain in 1990, ranking this problem fifth as a reason for all physician visits. Low back pain accounted for 2.8 percent of office visits in all three time periods. Nonspecific diagnostic labels were most common, and 56 percent of visits were to primary care physicians. Specialty variations were observed in caseload, diagnostic mix, and management. CONCLUSIONS: Back pain remains a major reason for all physician office visits. This study describes visit, referral, and management patterns among specialties providing the most care.

A comparison of the investment in hospital-based obstetrical ultrasound in Wales and Washington state.

The purpose of this study was to examine differences in the way Britain and the United States invest in and deploy a new medical technology. We used structured interviews to obtain information on the technical sophistication and approximate replacement value of all hospital-based obstetrical ultrasound machines in every maternity hospital in Washington state and Wales. The supply of hospital-based ultrasound machines--approximately two machines per 1,000 births--was similar in both countries. Wales had fewer advanced ultrasound machines than Washington state, and they were based exclusively in high-volume district general hospitals; there were no obstetric ultrasound machines in the private sector. In Washington state, the majority of advanced machines were in small and medium-sized hospitals, and many private offices had ultrasound machines. The approximate replacement value of hospital-based machines was three times as high per birth in Washington state as in Wales. In the case of obstetrical ultrasound, centralization of facilities, a relatively small private sector, and global budgeting lead to lower expenditures per patient within the National Health Service without compromising access to care.

From roadside to bedside: the regionalization of trauma care in a remote rural county.

OBJECTIVE: To determine the current role of rural hospitals and prehospital agencies in the care of motor vehicle crash victims in a remote, rural county prior to the statewide regionalization of trauma care. Specifically, we determined the proportion of crashes that required a response by emergency medical services (EMSs), the timeliness of the response, the proportion of patients treated in local hospitals, and the factors that predicted referral to trauma centers. DESIGN: Population-based retrospective cohort study linking emergency medical services, emergency department, and hospital discharge data to police motor vehicle crash reports and coroner data. SETTING: Okanogan County, Washington. SUBJECTS: All motor vehicle occupants, pedestrians or pedalcyclists who were involved in a motor vehicle collision with a response by emergency medical system personnel or the county coroner. INTERVENTION: None. MAIN OUTCOME MEASURES: EMS response times, emergency department and hospital discharge disposition, Injury Severity Scores, hospital length of stay, procedures, deaths. RESULTS: Twelve percent of 669 crashes reported to the police led to the dispatch of EMS. Crashes with EMS involvement were more likely to include occupants without restraints, who were ejected from the vehicle or who had alcohol as a contributing circumstance. The median interval between crash and EMS dispatch was 5 minutes (95th percentile: 40 minutes), the median scene time was 15 minutes (95th percentile: 35 minutes), and the median interval between dispatch and emergency department arrival was 48 minutes (95th percentile: 95 minutes). Among the 210 patients treated by EMSs, 67 (32%) were admitted to local hospitals, and 19 (9%) were referred to a distant trauma center. Of these, 17 were referred directly from the emergency department, one from the scene, and one after local admission. Compared with patients who were admitted locally, referred patients had a significantly higher mean Injury Severity Score (14.4 vs. 5.1), hospital length of stay (9.1 vs. 1.8 days), and rate of operative procedures (37% vs. 9%). Of the 13 crash-related deaths during the year, nine were declared dead at the scene before EMS arrival, three were asystolic at the time of EMS arrival at the scene, and one died at a referral hospital. CONCLUSIONS: The linkage of data from police, prehospital agencies, and hospitals can reveal important information about the sequence of health care for trauma patients. The rural hospitals in this county currently play a major role in the stabilization and treatment of motor vehicle crash victims.

Two decades of experience in the University of Washington Family Medicine Residency Network: practice differences between graduates in rural and urban locations.

This study describes how graduates of the University of Washington Family Medicine Residency Network who practice in rural locations differ from their urban counterparts in demographic characteristics, practice organization, practice content and scope of services, and satisfaction. Five hundred and three civilian medical graduates who completed their residencies between 1973 and 1990 responded to a 27-item questionnaire sent in 1992 (84% response rate). Graduates practicing outside the United States in a specialty other than family medicine or for fewer than 20 hours per week in direct patient care were excluded from the main study, leaving 116 rural and 278 urban graduates in the study. Thirty percent of graduates reported practicing in rural counties at the time of the survey. Rural graduates were more likely to be in private and solo practices than urban graduates. Rural graduates spent more time in patient care and on call, performed a broader range of procedures, and were more likely to practice obstetrics than urban graduates. Fewer graduates in rural practice were women. A greater proportion of rural graduates had been defendants in medical malpractice suits. The more independent and isolated private and solo practice settings of rural graduates require more practice management skills and support. Rural graduates' broader scope of practice requires training in a full range of procedures and inpatient care, as well as ambulatory care. Rural communities and hospitals also need to develop more flexible practice opportunities, including salaried and part-time positions, to facilitate recruitment and retention of physicians, especially women.

Abortions in rural Idaho: physicians' attitudes and practices.

This study surveyed all family physicians, obstetrician-gynecologists, and general surgeons practicing in rural Idaho in 1994. Although most respondents provided a wide range of reproductive health services, less than 4% performed abortions, so most rural Idaho women wanting abortions must travel long distances for this procedure. Physicians report that they do not provide abortion services because of both their own moral objections and local community opposition to the procedure. Yet 26% of the respondents indicated interest in using RU-486 for abortions when it becomes available. This suggests that the development of acceptable medical abortifacients may improve access to this procedure even in very conservative rural areas.

The diffusion of obstetric technology into rural U.S. hospitals.

We determined the distribution and sophistication of obstetric technologies in all 80 maternity hospitals in the state of Washington and examined the effect of rural or urban location, birth volume, and physician staffing on technological intensity. Although smaller and more rural hospitals refer most premature and low-birth-weight infants to regional referral centers, sophisticated prenatal and intrapartum technologies are available in the majority of even the smallest and most remote rural units. Rural hospitals have slightly lower obstetrical intervention rates than do their urban counterparts, but the differences are not great.

Rural hospital inpatient surgical volume: cutting-edge service or operating on the margin?

Surgical services are an important part of modern health care, but providing them to isolated rural citizens is especially difficult. Public policy initiatives could influence the supply, training, and distribution of surgeons, much as they have for rural primary care providers. However, so little is known about the proper distribution of surgeons, their contribution to rural health care, and the safety of rural surgery that policy cannot be shaped with confidence. This study examined the volume and complexity of inpatient surgery in rural Washington state as a first step toward a better understanding of the current status of rural surgical services. Information about rural surgical providers was obtained through telephone interviews with administrators at Washington's 42 rural hospitals. The Washington State Department of Health's Commission Hospital Abstract Recording System (CHARS) data provided a count of the annual surgical admissions at rural hospitals. Diagnosis-related group (DRG) weights were used to measure complexity of rural surgical cases. Surgical volume varied greatly among hospitals, even among those with a similar mix of surgical providers. Many hospitals provided a limited set of basic surgical services, while some performed more complex procedures. None of these rural hospitals could be considered high volume when compared to volumes at Seattle hospitals or to research reference criteria that have assessed volume-outcome relationships for surgical procedures. Several hospitals had very low volumes for some complex procedures, raising a question about the safety of performing them. The leaders of small rural hospitals must recognize not only the fiscal and service benefits of surgical services--and these are considerable--but also the potentially adverse effect of low surgical volume on patient outcomes. Policies that encourage the proper training and distribution of surgeons, the retention of basic rural surgical services, and the rational regionalization of complex surgery are likely to enhance the convenience and safety of surgery for rural citizens.
