Decline in physician referrals to health department clinics for immunizations: the role of vaccine financing

BACKGROUND: Physicians frequently refer children to health department clinics (HDCs) for immunizations because of high out-of-pocket costs to parents and poor reimbursement for providers. Referrals for immunizations can lead to scattered care. In 1994, two vaccine financing reforms began in New York State that reduced patient costs and improved provider reimbursement: the Vaccines for Children Program (VFC, mostly for those on Medicaid and uninsured) and a law requiring indemnity insurers to cover childhood immunizations and preventive services. OBJECTIVE: To measure reported changes in physician referrals to HDCs for immunizations before and after the vaccine financing reforms. DESIGN: In 1993, a self-administered survey measured immunization referral practices of primary care physicians. In 1997, we resurveyed respondents of the 1993 survey to evaluate changes in referrals. SETTING/ PARTICIPANTS: Three hundred twenty-eight eligible New York State primary care physicians (65% pediatricians and 35% family physicians) who responded to the 1997 follow-up immunization survey (response rate of 82%).Results: The proportion of physicians reporting that they referred some or all children out for immunizations decreased from 51% in 1993 to 18% in 1997 (p<0.001). In 1997, physicians were more likely to refer if they were family physicians (28% vs. 13%,p<0.01), or did not obtain VFC vaccines (29% vs. 13%,p<0.001). According to physicians who referred in 1993, decreased referrals in 1997 were due to the new insurance laws (noted by 61%), VFC (60%), Child Health Plus (a statewide insurance program for poor children, 28%), growth in commercial managed care (23%), Medicaid managed care (19%), and higher Medicaid reimbursement for immunizations that is due to VFC (18%). For physicians noting a decline in referrals, the magnitude of the decline was substantial-60% fewer referrals for VFC-eligible patients and 50% fewer for patients eligible under the new insurance law. CONCLUSIONS: Vaccine financing reforms decreased the proportion of physicians who referred children to HDCs for immunizations, and may have reduced scattering of pediatric care.     

To give or not to give: Approaches to early childhood immunization delivery in Oregon rural primary care practices

Context: Little is known about rural clinicians’ perspectives regarding early childhood immunization delivery, their adherence to recommended best immunization practices, or the specific barriers they confront. Purpose: To examine immunization practices, beliefs, and barriers among rural primary care clinicians for children in Oregon and compare those who deliver all recommended immunizations in their practices with those who do not. Methods: A mailed questionnaire was sent to all physicians, nurse practitioners, and physician assistants practicing primary care in rural communities throughout Oregon. Findings: While 39% of rural clinicians reported delivering all childhood immunizations in their clinic, 43% of clinicians reported that they refer patients elsewhere for some vaccinations, and 18% provided no immunizations in the clinic whatsoever. Leading reasons for referral include inadequate reimbursement, parental request, and storage and stocking difficulties. Nearly a third of respondents reported that they had some level of concern about the safety of immunizations, and 14% reported that concerns about safety were a specific reason for referring. Clinicians who delivered only some of the recommended immunizations were less likely than nonreferring clinicians to have adopted evidence‐based best immunization practices. Conclusions: This study of rural clinicians in Oregon demonstrates the prevalence of barriers to primary care based immunization delivery in rural regions. While some barriers may be difficult to overcome, others may be amenable to educational outreach and support. Thus, efforts to improve population immunization rates should focus on promoting immunization “best practices” and enhancing the capacity of practices to provide immunizations and ensuring that any alternative means of delivering immunizations are effective.     

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.     

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.     

Physician Perceptions of Practice Environment and Professional Satisfaction in California: From Urban to Rural

CONTEXT: Few studies have systematically examined the experience of rural practice from the physician's perspective or included physicians from an array of specialties, particularly non-primary care. PURPOSE: To better understand differences between rural and urban physicians in perceptions of their practice environment. METHODS: In 2001-2002, self-administered questionnaires were sent to a probability sample of primary care and specialist physicians identified from the American Medical Association's Physician masterfile in California. Logistic regression was performed to model the effect practice location had on key variables, controlling for physician demographics, specialty, and the insurance profile of the physician's patients. FINDINGS: Completed questionnaires were obtained from 1,365 of 2,240 eligible urban physicians (61%), and 398 of 632 rural physicians (63%). Among primary care physicians, those in rural areas defined as nonadjacent or small non-metropolitan counties were the least likely to report pressures to see more patients, limit referrals, and limit treatment options. In contrast, among specialists, those in rural areas within metropolitan areas (or in large adjacent non-metropolitan counties) were more likely than urban specialists to report practice pressures. Although rural physicians in both primary care and specialist fields were more likely than urban physicians to report difficulty attracting new physicians to their communities, they perceived their overall practice climate to be better. Physicians in the nonadjacent-or-small non-metropolitan category were the most satisfied, but specialists in the nonadjacent-or-small non-metropolitan category were the least satisfied. CONCLUSION: Physicians in rural California appear to have maintained a greater sense of clinical autonomy and higher professional satisfaction compared with their urban counterparts.     

Rural–Urban Differences in Primary Care Physicians' Practice Patterns, Characteristics, and Incomes

ABSTRACT:  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.     

Physician attitudes and beliefs associated with patient pneumococcal polysaccharide vaccination status

BACKGROUND: Barriers to adult immunizations persist as current rates for pneumococcal polysaccharide vaccine (PPV) receipt among eligible adults remain below national goals. This study investigated potential barriers to patients receiving the PPV, including predisposing, enabling, environmental and reinforcing factors among physicians from a variety of practice and geographic settings. METHODS: Participants were 60 primary care physicians from inner-city, rural, suburban, and Veterans Affairs practices, which included adults aged 65 years and older. Elderly patients able to complete a telephone interview were randomly selected from each physician's practice. RESULTS: Self-reported PPV vaccination status was significantly related to physician report of routinely providing PPV to their patients and to the practice providing immunization clinics or other immunization promotion programs. Physicians who were highly unlikely to refer uninsured adults to health departments for immunizations had a significantly higher percentage of patients reporting receipt of PPV (P = .03). CONCLUSIONS: Enabling and environmental factors related to physicians, such as economic and insurance issues, were significant barriers to PPV vaccination. Vaccination rates might be improved through efforts that reduce likelihood of referral for immunizations and office systems that support immunization, such as patient and provider reminders and express vaccination clinics.     

Physician credentials and practices associated with childhood immunization rates: Private practice pediatricians serving poor children in New York City

Private practice physicians in New York City’s poorest neighborhoods are typically foreign trained, have generally substandard clinical practices, and have been accused of rushing Medicaid patients through to turn a profit. However, they also represent a sizable share of physician capacity in medically underserved neighborhoods. This article documents the level of credentials, systems, and immunization-related procedures among these physicians. Furthermore, it assesses the relationship between such characteristics and childhood immunization rates. The analysis utilizes a cross-sectional comparison of immunization rates in 60 private practices that submitted 2,500 or more Medicaid claims for children. Immunization data were gathered from medical records for 2,948 randomly selected children under 3 years of age. Half of sampled physicians were board certified (55%), and half were accepted by the Medicaid P referred P hysicians and Children (P P AC) program (51.7%). Of physicians, 43% saw patients only on a walk-in basis, while only 17% scheduled the next appointment while the patient was still in the office. There were 75% of the physicians who reported usually immunizing at acute care visits. Immunization rates were higher among PPAC physicians compared to others (41% vs. 29% up to date for diphtheria and tetanus toxoids and pertussis [DTP]/Haemophilus influenzae type b [Hib], polio, and measles-mumps-rubella [MMR], P=.01), and board-certified physicians showed a trend tovard better immunization rates (39% vs. 30%, P=.07). Physicians who reported usually immunizing at acute care visits also had higher rates than those who did not (38% vs. 27%, P=.05). Scheduling a date and time for the next immunization showed a trend toward association with immunization coverage (37% vs. 28%, P=.10). Private practice physicians who provide high volumes of care reimbursed by Medicaid have improved their credentials and affiliations over time, thereby expanding reimbursement options. Credentials and affiliations were at least as effective in distinguishing relatively high- and low-performing physicians, as were immunization-related practices, suggesting that they are useful markers for higher quality care. The relative success of the P P AC programshould informefforts to inprove the capacity and quality of primary care for vulnerable children. Appointment and reminder systems that effectively manage the flow of children back into the office for immunizations and the vigilant use of acute care visits for immunizations go hand in hand. Opportunity exists for payers and plans to encourage and support these actions. This research was supported by the Centers for Disease Control and Prevention through contract 9775565 with the New York City Department of Health.     

To Stay or Not to Stay: Issues in Rural Primary Care Physician Retention in Eastern Kentucky

An important aspect of primary care physician availability is the retention of physicians once they have located. While retention has been under-researched compared to recruitment, it is especially important in rural areas where physician shortages already exist. This study reports the results of a retention survey completed by 132 primary care physicians in rural eastern Kentucky. The survey sets up an objective, hypothetical retention scenario and asks physicians to respond to structured questions and to an open-ended question about factors not appearing in the survey. In response to the structured portion of the survey, physicians indicate that relief coverage is the most important factor in rural physician retention. A content analysis of 75 open-ended responses reveals that besides the other factors in the survey, "sociocultural integration" is the pre-eminent retention issue for rural practitioners. This article concludes that the role of the local rural community may be more important in retention than in recruitment. Finally, it is suggested that additional in-depth qualitative research be conducted within the local contexts to enhance the understanding of rural physician retention processes.     

Family Medicine Spokane Rural Training Track: 24 years of rural-based graduate medical education

Twenty percent of the US population lives in rural communities, but only about 9% of the nation's physicians practice in those communities. There is little doubt that the more highly specialized physicians are, the less likely they are to practice or settle in rural areas. There is clearly a population threshold below which it is not feasible for specialist (in contrast to generalist) physicians to pursue the specialty in which they have trained. Much of rural America falls below that threshold. This leaves large geographic areas of America to the primary care physician. The proportional supply of family physicians to specialists increases as urbanization decreases. Family physicians are the largest single source of physicians in rural areas. Family medicine residency programs based in rural locations provide a critical mechanism for addressing rural primary care needs. Graduates from rural residency programs are three times more likely to practice in rural areas than urban residency program graduates. There are two primary goals of training residents in rural areas: producing more physicians who will practice in rural areas and producing physicians who are better prepared for the personal and professional demands of rural practice. Rural Training Tracks, where the first year of residency is completed in an urban setting and the second and third years at a rural site (1-2 model), initially proposed by Family Medicine Spokane in 1985, have been highly successful in placing and maintaining more than 70% of their graduates in rural communities. Similar and modifications of the "Spokane RTT model" have been established around the country. Now, more than 24 years of educational experience has been accumulated and can be applied to further development of these successful family medicine residency programs.     

The effect of race and residence on the receipt of childhood immunizations: 1993-2001

OBJECTIVE: To determine if rural minority children ages 3-71 months are more likely than similar aged urban minorities to have delays in their immunization status. METHODS: Secondary analysis of the National Health Interview Survey (NHIS) for the years 1993-2001. FINDINGS: There were no substantial differences between the up-to-date immunization status of children living in metropolitan areas compared to children living in rural areas. There does appear to be a delay in introducing new vaccines into rural areas compared to metropolitan areas during the first 2 years of the vaccine recommendation. There were no significant differences in immunization status between Whites, Blacks and Hispanics living in metropolitan and rural areas. CONCLUSIONS: Rural minority children are no more likely than other children to have delayed immunizations.     

The increasing supply of physicians in US urban and rural areas, 1975 to 1988.

BACKGROUND. Despite the rapid growth of the US physician supply since the mid-1970s, it remains unclear whether physicians have spread into the most rural areas of the country. This report examines the urban-rural distribution of physicians between 1975 and 1988. METHODS. A county-based typology of the urban-rural continuum was employed to examine trends in the supply of nonfederal primary care physicians, specialist physicians, and osteopaths. RESULTS. All urban and rural areas gained physicians during the late 1970s and 1980s. The supply of physicians increased most rapidly in metropolitan counties. Within nonmetropolitan areas, urbanized remote counties became more prominent centers of the physician supply. Osteopaths were more likely to locate in the most rural areas than allopaths. The physician supply in all areas also became more specialized over time. CONCLUSIONS. The rapid growth of the US physician supply was associated with the spread of more practitioners into all parts of the country. However, the supply of physicians increased most rapidly in urban areas, widening urban-rural differences in the availability of physicians.     

Primary care physician perceptions of the nurse practitioner in the 1990s.

OBJECTIVE: To evaluate factors associated with primary care physician attitudes toward nurse practitioners (NPs) providing primary care. DESIGN: A mailed survey of primary care physicians in Iowa. SETTING AND PARTICIPANTS: Half (N = 616) of the non-institutional-based, full-time, primary care physicians in Iowa in spring 1994. Although 360 (58.4%) responded, only physicians with complete data on all items in the model were used in these analyses (n = 259 [42.0%]). MAIN OUTCOME MEASURES: There were 2 principal dependent measures: physician attitudes toward NPs providing primary care (an 11-item instrument) and physician experience with NPs in this role. Bivariate relationships between physician demographic and practice characteristics were evaluated by chi 2 tests, as were both dependent variables. Ordinary least-squares regression was used to determine factors related to physician attitudes toward NPs. RESULTS: In bivariate analyses, physicians were significantly more likely to have had experience with an NP providing primary care if they were in pediatrics or obstetrics-gynecology (78.3% and 70.0%, respectively; P < .001), had been in practice for fewer than 20 years (P = .045), or were in practices with 5 or more physicians. The ordinary least-squares regression indicated that physicians with previous experience working with NPs providing primary care (P = .01), physicians practicing in urban areas with populations greater than 20,000 but far from a metropolitan area (P = .03), and general practice physicians (P = .04) had significantly more favorable attitudes toward NPs than did other primary care physicians. CONCLUSIONS: The association between previous experience with a primary care NP and a more positive attitude toward NPs has important implications for the training of primary care physicians, particularly in community-based, multidisciplinary settings.     

A Preschool Immunization Project to Enhance Immunization Levels, the Public-Private Relationship, and Continuity of Care

This study was conducted to determine whether implementing a program aimed at providing a variety of incentives to physicians who provide immunizations to preschool-aged children would help to improve immunization rates and reduce fragmented care for patients. Twenty physicians from 14 private practices that provide care to preschool-aged children from low income families in suburban Cook County, Illinois participated in the project. A randomly selected subset of patient case records from the physicians' offices were audited after the implementation of the project to determine the immunization status of children in the practices and the nature of services provided. These 310 records of children under three years of age who were treated between 1991-1994 (the intervention sample) were compared to 310 charts from a 1988-1990 cohort of records (baseline sample). The groups did not differ on race or gender; however, significantly more families in the 1988 through 1990 cohort of children under 3 years of age were insured privately when compared to the 1991 through 1994 cohort. Seventy percent (218) of the records in the intervention sample were up to date for age on immunizations compared to 45% (141) of the baseline records, reflecting a statistically significant difference (p < .00001). The intervention sample showed significantly more well child visits where immunizations were given and follow up visits where immunizations were given when compared to the baseline sample. Physicians completed surveys before and after implementation of the project. They were questioned about their knowledge and practices regarding immunizations as well as their opinion of specific project components. All of the physicians viewed the project as an effective means to improve immunization services to low income children. The project demonstrates a potential means of enhancing immunization levels and continuity of care among preschool-aged children. It also highlights the workable nature of the partnership between public and private sectors.     

Self-report of delivery of clinical preventive services by U.S. physicians. Comparing specialty, gender, age, setting of practice, and area of practice.

OBJECTIVES: To summarize national survey results for key clinical preventive services provided by primary care physicians, characterize the results by demographic and practice attributes of the respondents, and compare the results to those obtained in other studies. DESIGN: Cross-sectional study. PARTICIPANTS: A total of 3881 clinicians who provided primary care at least 50% of their time, randomly sampled from the professional associations representing family practitioners, pediatricians, internists, and OB-GYNs. MEASURES: The Primary Care Providers Survey instrument of 1992, administered through the Office of Disease Prevention and Health Promotion, designed to assess the provision of clinical preventive services by primary caregivers. MAIN RESULTS: Few of the physicians surveyed reported providing most indicated clinical preventive services more than 80% of the time. For the purposes of this paper, > 80% provision of preventive services is considered adequate. Female physicians reported providing more preventive services involving exercise, diet, alcohol/drugs, seatbelts, sexual activity, family planning, immunizations, and screening procedures. Physicians aged < 50 reported providing more preventive services involving smoking, alcohol/drugs, seatbelts, sexual activity, and family planning. Older physicians generally reported more delivery of vaccines and screening procedures. Practitioners from big metropolitan areas reported more preventive services involving alcohol/drugs and family planning while respondents in rural areas reported less immunizations and screening procedures. When analyzed by specialty, physicians reporting the most preventive care varied by type of preventive care. CONCLUSIONS: Small differences in the self-report of provision of clinical preventive services between specialties and demographic subgroups did exist. At the time of this survey, however, no group of primary care physicians reported providing clinical preventive services to their patients at adequate levels.     

Do International Medical Graduates (IMGs) “Fill the Gap” in Rural Primary Care in the United States? A National Study

ABSTRACT:  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 .     

Physicians who do and do not recommend children get all vaccinations

The objectives of this study were to determine (1) the proportion of physicians who do and do not recommend that children receive all available vaccines and (2) physician characteristics, attitudes, and behaviors associated with not recommending children receive all vaccines. A self-administered, cross-sectional electronic survey of physicians was conducted in 2005. Analyses were restricted to pediatricians (n = 250) and family practitioners (n = 484) who indicated they see at least five pediatric patients per week. A total of 1,935 surveys were distributed, and 1,251 (65%) physicians responded. Eleven percent of the physicians included in the analysis did not recommend to parents that children receive all available vaccines. Compared with physicians who recommended all vaccines for children, physicians who did not were more likely to be family practitioners versus pediatricians (OR = 2.9, CI = 1.4-5.8), agree or be neutral versus disagree that they have some concerns about childhood immunization safety (OR = 3.1, CI = 1.8-5.2), and have or= 8 physicians in their practice (OR = 2.0, CI = 1.1-3.7). We conclude that physician characteristics and concerns about childhood immunizations are associated with not recommending all childhood vaccines. Further investigation of physicians' concerns about vaccine safety is needed to improve health communications directed toward health care providers.     

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.     

Rural Health Policy: Physician Assistants and Nurse Practitioners: Rural-Urban Settings and Reimbursement for Services

Evidence based on productivity measures, salaries and costs of medical education indicates that physician assistants and nurse practitioners are cost-effective. Managed care suggests that health maintenance organizations (HMOs) would seek to utilize these professionals. Moreover, underserved rural areas would utilize physician assistants and nurse practitioners to provide access. This study examined the role of payment sources in the utilization of physician assistants and nurse practitioners using the 1994 National Hospital Ambulatory Medical Care Survey (NHAMCS) conducted by the National Center for Health Statistics, U.S. Centers for Disease Control and Prevention. Rural vs. urban results were compared. The study found that significant rural-urban differences exist in the relationships between payment sources and the utilization of physician assistants and nurse practitioners. The study also found that payment source affects varied for physicians, physician assistants and nurse practitioners who saw outpatients in hospital settings. Surprisingly, prepaid and HMO types of reimbursements are shown to have no relationship with physician assistant and nurse practitioner utilization, and this finding is the same for both rural and urban patient visits. After controlling for other influences, the study shows that physicians, physician assistants and nurse practitioners are each as likely as the other to be present at a rural managed care visit. However, physicians are much more likely than physician assistants and nurse practitioners to be present at an urban managed care visit.
