Influences on the receipt of well-child visits in the first two years of life.

OBJECTIVE: To determine demographic and health care system factors associated with children receiving an adequate number of well-child visits (WCVs). METHODS: Information on 4385 children and their families was obtained via birth certificates, parent interviews, chart review of outpatient sites of care, and insurance records. RESULTS: Only 77% of children received at least five WCVs by age 2. In regression analysis, the factors most strongly associated with children's total number of WCVs were delay in the initiation of prenatal care (odds ratio = 0.6) and receipt of all outpatient care in private physician offices (odds ratio = 4.2 to 5.6). Having an adequate number of WCVs was associated with being up to date for immunizations. CONCLUSIONS: Children of mothers who delay prenatal care are at high risk for not receiving adequate numbers of WCVs. Recognition of this marker can allow for targeted interventions that aim to ensure that children receive appropriate preventive care.

Vaccine-associated liability risk and provider immunization practices.

OBJECTIVE: To explore the effect of concern about vaccine-associated malpractice litigation on provider immunization practices and attitudes. DESIGN: A cross-sectional mail survey. PARTICIPANTS: One thousand one hundred sixty-five pediatricians and 1849 family physicians. MAIN OUTCOME MEASURES: Physicians' perceptions of the legal and financial risks of providing immunizations and of the liability protection afforded by state programs and their current immunization practices. RESULTS: The response rate was 72% for pediatricians and 63% for family physicians. Overall, less than 30% of the respondents believed that federal and state programs protect them against vaccine-related lawsuits, with pediatricians more likely to believe so (32% vs 21%, P < .0001). Pediatricians were also more likely than family physicians to believe that the diphtheria, tetanus, and pertussis vaccine could be administered safely to children with a family history of seizures, a minor respiratory tract illness, or a previous local reaction to the vaccine. Liability issues were not significantly associated with any of the outcome variables, except that those physicians who believed that the whole-cell diphtheria, tetanus, and pertussis vaccine increased their risk for lawsuits were less likely to indicate that the diphtheria, tetanus, and pertussis vaccine was safe for children with a family history of seizures (P < .001). CONCLUSIONS: Liability-related variables were not independently associated with most immunization behaviors examined. This raises the question as to whether physicians cite liability as a reason for not immunizing children with acute and chronic illnesses, when their concerns are actually otherwise. These data suggest that educational efforts focused on liability issues alone will have little effect on inappropriate delaying of immunization for these children. Rather, education is needed regarding inappropriate contraindications themselves.

Impact of North Carolina's universal vaccine purchase program by children's insurance status.

OBJECTIVE: To examine the impact of a new universal purchase vaccine program on immunization rates of children with different types of insurance. DESIGN: Ecologic study using parent telephone interviews, medical chart abstraction in sites of outpatient care, and insurance verification with Medicaid and private insurers. SETTING: State of North Carolina. PARTICIPANTS: Of a random birth certificate sample of 4385 children born in North Carolina during 1994 and 1995, 507 were excluded. A total of 2767 children had completed parent interviews; 95% of those had medical chart abstraction and insurance data. MAIN OUTCOME MEASURES: Immunization rates at each month during the first 2 years of age, site of delivery for immunizations and well-child visits, and insurance status. RESULTS: In month-by-month comparisons, children born in 1995 had immunization rates 4% to 10% higher than their 1994 counterparts. By 24 months of age, 84% of the 1995 cohort had completed the primary immunization series, compared with 79% of the 1994 cohort (P<.001). In all insurance subgroups, 1995 immunization rates were higher than 1994 rates. The largest increases occurred among privately insured children with no well-child coverage, children who had periods of being uninsured, and children enrolled in Medicaid exclusively or with private insurance. More children in the 1995 cohort received immunizations in the private sector. CONCLUSIONS: Implementation of North Carolina's universal purchase program was associated with improved immunization rates, especially for children with inadequate insurance for well-child care. However, insurance status still influences the ability of children to receive immunizations on schedule.

Variation in patient charges for vaccines and well-child care.

BACKGROUND: Several state and federal programs have attempted to boost immunization rates by reducing or eliminating provider vaccine costs. The relation between patient vaccine and well-child visit charges and vaccine financing systems is unknown. OBJECTIVES: To determine patient charges for vaccines and well-child visits in three states with varying vaccine financing systems and to examine the effects of a short-term reduction in provider vaccine costs. DESIGN: Cross-sectional survey study of a random sample of physicians in three states. PARTICIPANTS: A total of 2797 pediatricians and family physicians in North Carolina, Texas, and Massachusetts were surveyed. MAIN OUTCOME MEASURES: Current charges to patients for diphtheria-tetanus-pertussis vaccine (DTP), measles-mumps-rubella vaccine, Haemophilus influenzae type b vaccine (Hib), and combined DPT-Hib vaccine for well-child visits; changes in charges over the previous 8 months. RESULTS: Response rate was 62%. Vaccine and well-child visit charges were comparable in North Carolina and Texas. Massachusetts' average charges for well-child visits were higher than in the other states, although vaccine charges were lower; with the use of combined DPT-Hib vaccine, total simulated charges for vaccines and well-child care during the first 6 months of life averaged only 10% less in Massachusetts vs Texas and North Carolina. Neither regional variation in cost of living nor Medicaid reimbursement rates explained this difference. CONCLUSIONS: The average cost and composition of charges for well-child care in Massachusetts, a state with universal purchase of vaccines, compared with the other states, warrant further study to explore whether physicians shift costs to other preventive services to compensate for lower allowable immunization charges. If such cost shifting occurs, current federal immunization initiatives that lower or eliminate provider cost may not provide increased access to preventive services.

Impact of a new universal purchase vaccine program in North Carolina.

OBJECTIVE: To explore the effects of state universal purchase (UP) of vaccines for all children, regardless of income or insurance status, on North Carolina physicians and families. DESIGN: Cross-sectional survey. PARTICIPANTS: Pediatricians and family physicians (N = 2163) were surveyed in 1995 to compare immunization charges in North Carolina (new UP) with those of Massachusetts (UP) and Texas (free market). MAIN OUTCOME MEASURES: Patient charges for immunizations and well-child visits and physician perceptions of the effects of state immunization programs. Models were devised to simulate the net effect of the North Carolina UP program on immunization revenue for physicians and on families' out-of-pocket costs for well-child care. RESULTS: Physician participation rates in the 2 UP programs were very high. North Carolina physicians reported substantial decreases in immunization charges and reduced referrals to public clinics, but thought that UP increased their administrative burden. Sixty percent of North Carolina physicians increased charges for well-child visits, nearly twice that in the 2 control states. Families who previously had received immunizations from public clinics but chose to remain in the private-sector "medical home" for immunizations after implementation of UP had increased out-of-pocket expenses that varied by their insurance status. CONCLUSIONS: The North Carolina UP program is effective in decreasing patient immunization charges and reducing referrals to public clinics. However, UP does not eliminate cost as a barrier to immunization, nor does it enable all children to remain in their medical homes. Underinsured children still may face considerable financial barriers to immunization in a UP system.

Medical education and the retention of rural physicians.

OBJECTIVE: This study inquires whether retention in rural practice settings is longer for graduates of public medical schools and community hospital-based residencies, and for those who participated in rural rotations as medical students and residents. These questions are addressed separately for "mainstream" rural physicians and physicians serving in the National Health Service Corps (NHSC). DESIGN: Design is a prospective cohort study. PARTICIPANTS: Study subjects were 202 primary care physicians who graduated from U.S. allopathic medical schools from 1970-1980, and who in 1981 were working in a nationally representative sample of externally subsidized rural practices. Nearly half were serving in the NHSC. Physicians were first identified in 1981 as part of an earlier study. INTERVENTION: In 1990, study subjects were re-located and sent a follow-up mail survey inquiring about their medical training backgrounds and their careers from the time of graduation until 1990. We examined associations between four features of physicians' medical training and their subsequent retention in rural practice settings. RESULTS: Among those not in the NHSC, rural retention duration did not differ for those from public versus private medical schools, those who trained in community hospitals versus university hospital-based residencies, or for those who completed versus did not complete rural rotations as students or residents. Among NHSC physicians, no retention duration differences were noted for those with rural experiences as students or residents, or for those trained in community hospital residencies. Contrary to common wisdom, public school graduates in the NHSC remained in rural areas for shorter periods than private school graduates. CONCLUSIONS: These findings call into question whether current rural-focused medical education initiatives prepare rural physicians in ways able to influence their retention in rural settings. For purposes of enhancing the rural practice retention of its alumni, the NHSC should not selectively award scholarships to students from public medical schools.

Medical education and physicians' career choices: are we taking credit beyond our due?

There is great enthusiasm for curricula that place students and residents in community-based primary care practices and in rural and underserved areas. Interest in these primary care training experiences is based, in part, on studies that report that they can prompt learners to pursue careers in primary care specialties and underserved areas. Given that these programs attract learners with prior career interests in primary care and underserved area medicine, however, it might be that the favored career choices of their graduates are better explained by programs' selection than by their curricula. In studies where learners are randomly assigned to various training programs, no curriculum effect is found, at least for the typical one- or two-month primary care and rural rotation. Only in studies of longitudinal, multidimensional programs have career effects been demonstrated when learners are randomized. The need for a balanced physician workforce, and therefore the need for curricula to create it, demands ongoing, rigorous assessments of the efficacies of the various primary care training programs. Critical reevaluation will probably show that most schools and residencies need extensive curriculum changes if learners' careers are to be affected, and that admission committees can play a pivotal role in creating a balanced physician workforce. These discussions challenge educators to be as thoughtful and as empirically grounded as possible when changing the content and process of medical training.

Preparing and retaining rural physicians through medical education.

PURPOSE: To identify educational approaches that best prepare physicians for rural work and small-town living, and that promote longer rural practice retention. METHOD: In two mail surveys (1991 and 1996-97), the authors collected data from primary care physicians who had moved to rural practices nationwide from 1987 through 1990. A total of 456 eligible physicians responded to both surveys (response rate of 69.0%). The authors identified those features of the physicians' training that correlated with their self-reported preparedness for rural practice and small-town living, and with how long they stayed in their rural practices. Analyses controlled for six features of the physicians and their communities. RESULTS: The physicians' sense of preparedness for small-town living predicted their retention duration (hazard ratio, 0.74, p < .0001), whereas their preparedness for rural medical practice did not predict their retention duration after controlling for preparedness for small-town living (hazard ratio, 0.92; p = .27). For the physicians who had just finished their training, only a few features of their training predicted either rural preparedness or retention. Residency rural rotations predicted greater preparedness for rural practice (p = .004) and small-town living (p = .03) and longer retention (hazard ratio, 0.43, p = .003). Extended medical school rural rotations predicted only greater preparedness for rural practice (p = .03). For the physicians who had prior practice experience, nothing about their medical training was positively associated with preparedness or retention. CONCLUSION: Physicians who are prepared to be rural physicians, particularly those who are prepared for small-town living, stay longer in their rural practices. Residency rotations in rural areas are the best educational experiences both to prepare physicians for rural practice and to lengthen the time they stay there.

Rural physician satisfaction: its sources and relationship to retention.

This study uses survey data to identify areas of satisfaction and dissatisfaction for primary care physicians working in rural areas across the country. It also identifies the specific areas of satisfaction associated with longer retention within a given rural practice, as well as the characteristics of individuals, practices, jobs, and communities associated with the areas of satisfaction that predict retention. Study subjects comprised a sample of 1,600 primary care physicians who moved to nonmetropolitan counties nationwide during the years 1987 through 1990, with oversampling of those who moved to federally designated health professional shortage areas (HPSAs). Physicians serving in the National Health Service Corps (NHSC) were excluded. Sixty-nine percent of the eligible subjects returned completed mail questionnaires in 1991. Analyses for this study were limited to the 620 primary care physicians who worked more than 20 hours per week in towns of fewer than 35,000 population; who were neither in the military nor the NHSC; and who were not in urgent care, emergency room, or full-time teaching positions. Analyses revealed that the areas of rural physicians' greatest satisfaction were their relationships with patients, clinical autonomy, the care they provided to medically needy patients, and life in small communities. Physicians were least satisfied with their access to urban amenities and the amount of time they spent away from their practices. Retention was independently associated only with physicians' satisfaction with their communities and their opportunities to achieve professional goals. Retention was also marginally related to physicians' satisfaction with their earnings. Among the areas of satisfaction not related to retention were satisfaction with autonomy, access to medical information and consultants, and the quality of doctor-patient relationships. In a subsequent series of analyses of the factors that predict the three areas of satisfaction that were associated with retention (satisfaction with the community, professional goal attainment, and earnings), a variety of physician, work, and community factors were identified. These findings reveal that specific features of rural physicians, their work, and their communities predict each of the various aspects of satisfaction and that only certain aspects of satisfaction predict rural physicians' retention. There are no magic bullets to make rural physicians satisfied in all ways. Nevertheless, there are identified approaches to elevate the specific aspects of rural physicians' satisfaction important to their retention. Programs to improve the satisfaction of rural physicians should focus on those areas of satisfaction that predict longer retention and other important outcomes.

Studying the retention of rural physicians.

Rural communities and policy-makers struggle with efforts to enhance the retention of rural physicians. Research available to guide these efforts is often weak methodologically and thus may be pointing retention efforts in nonproductive directions. This article discusses a range of methodologic issues encountered in rural physician retention studies for the purpose of strengthening future studies. Ideal study approaches to answer causal questions, including questions about the "causes" of rural physician retention, must demonstrate good internal validity, for which chance, bias, and confounding are accounted. Retention studies that rely simply on asking physicians why they stay or leave rural areas can be useful at times, but are too prone to bias and their findings difficult to verify. Simply identifying what physicians find satisfying or dissatisfying about rural work also will not reliably reveal why they stay or leave, a related but still distinct question. Stronger approaches to studying retention include the traditional quantitative study--in which retention factors are identified when they are statistically related to physicians' retention, and the increasingly popular qualitative study--in which retention issues are revealed through prolonged, in-depth interactions with physicians. This article also discusses various definitions of retention, the use of survival curves to present retention findings, and the importance of studying retention in inception cohorts. The benefits and downside of studying retention with prospective and retrospective study designs are described.

Medical training debt and service commitments: the rural consequences.

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

Querying physicians' beliefs in career choice studies: the limitations of introspective causal reports.

Numerous studies in family medicine literature explore the determinants of physicians' specialty and practice location choices. A research approach frequently used in these studies has been to ask study physicians what led them to make specific career choices, labeled here as the introspective causal reports study design. This paper explores the validity of introspective causal reports and their usefulness in making health manpower policy recommendations. The accuracy of people's beliefs about the causes of their own behaviors is examined, and social psychology literature is drawn upon in this examination. Data are presented characterizing the use of introspective causal reports in recent family medicine literature. Recommendations are made for stronger research designs in future physician career choice determinant studies.

Primary care physicians' training and their community involvement.

BACKGROUND AND OBJECTIVES: Physicians who incorporate a community perspective into their clinical practice can provide more effective care, but little is known about the type of training that helps physicians include this perspective. This study examines associations between physicians' current level of involvement in their communities and a range of prior educational experiences. METHODS: We obtained data from 247 recently graduated primary care physicians through a nationwide mail survey. Physicians described their community-related training experiences during medical school and residency. They also described their current involvement in each of 4 domains of community work. Associations between different training experiences and physicians' current community involvement were examined. RESULTS: Subjects generally reported limited community-related training. Physicians who did receive training in content relevant to a given community domain were significantly more involved in that domain as practicing physicians. Rotating in rural locations and having a mentor active in the community also were associated with greater current community involvement. CONCLUSIONS: These data provide evidence that formal training experiences can influence how actively physicians will later interact with their communities. We should provide medical students and residents with educational content in all 4 domains of community work, place them in carefully selected locations, and arrange mentor relationships.

The four community dimensions of primary care practice.

BACKGROUND: Despite the growing belief that "the community" should play a larger role in the work of physicians, there is no clear understanding of exactly how physicians should participate in their communities. The primary goals of this study were to propose and test an organizing framework that identified four distinct categories of activities whereby physicians can interact with their communities: (1) identifying and intervening in the community's health problems; (2) responding to the particular health issues of local cultural groups when caring for patients; (3) coordinating local community health resources in the care of patients; and (4) assimilating into the community and its organizations. Other goals were to characterize physicians' level of involvement in each of these four types of community activities, and to identify the correlates of greater and lesser involvement. METHODS: A questionnaire was mailed to a random sample of 500 young primary care physicians in the United States. The response rate was 66.6%. Physicians reported how confident they were in performing each of 15 specific community-relevant activities. Confidence ratings were factor-analyzed to test the hypothesis that physician involvement in community activities can be organized into the four proposed categories. Physicians also self-rated their involvement in various community activities within each of these four categories, and predictors of involvement were identified through ordinary least-squares regression models. RESULTS: Using factor analysis, the community activities sorted cleanly into the four postulated community dimensions of medical practice, providing a measure of validation for the distinctiveness of the four dimensions. Physicians reported active involvement in some activities (eg, speaking to community groups and gaining acceptance in their communities) and little involvement in other activities (eg, working with community groups to address local health problems, familiarity with local women's shelters). Contrary to expectations, physicians who worked with minority and poorer patient populations and counties generally reported less community involvement. Physicians caring for more patients covered by HMO or capitated health insurance plans also reported lower participation in their communities. CONCLUSIONS: This study provides support for the hypothesis that the community plays a role in the work of physicians that can be categorized into four types of activities. This framework may help physicians and practices recognize the breadth of ways they can meet the growing demand that they approach their work with a community perspective.

Pediatrician and family physician agreement with and adoption of universal hepatitis B immunization.

BACKGROUND: The purpose of this study was to assess (1) rates of agreement with and adoption of the universal hepatitis B vaccine recommendation among practicing pediatricians and family physicians in nine selected states; (2) physicians' attitudes related to hepatitis B immunization; and (3) physicians' perceptions of parental attitudes regarding the hepatitis B vaccine series. METHODS: Self-administered questionnaires were mailed to 3014 pediatricians and family physicians in selected metropolitan areas and non-metropolitan areas of nine states. Outcome variables were agreement with and adoption of the hepatitis B vaccine recommendation. Predictor variables included physicians' characteristics, practice type and location, and proportion of managed care and Medicaid patients. Other variables that were studied include physicians' attitudes related to hepatitis B immunization, sources of immunization recommendation information, personal completion of the hepatitis B immunization series, and physicians' impressions of parental attitudes about the vaccine. RESULTS: Pediatricians were more likely than family physicians to report that they knew "a lot" about the recommendation (95% vs 84%), agreed with it (83% vs 57%), and have adopted it into practice (90% vs 64%). More physicians in both specialties had adopted the recommendation than actually agreed with it. Doubt about long-term protection from the vaccine was a strong predictor of not agreeing with or adopting the recommendation. Parental resistance to or request for hepatitis B vaccine affected the likelihood of physicians adopting it. CONCLUSIONS: Pediatricians and family physicians continue to differ in both agreement with and adoption of universal hepatitis B immunization. Two years after the recommendation was made, less than two thirds of all family physicians have adopted this recommendation. Adoption is likely influenced by practice policy, physician attitudes, and perceived parental opinions. We recommend that as new vaccines are approved and recommended, research be conducted to explore and address issues germane to physician agreement and adoption.

The Vaccines For Children program: issues of physician accountability and patient verification.

To address the issue of low immunization rates, President Clinton in 1993 introduced the Child Immunization Initiative (CII). One part of the CII is the Vaccines for Children (VFC) program, a federally-funded and state-operated vaccine supply program. Recently, congress has raised concerns regarding the extent to which noneligible children may be receiving VFC vaccine. This article explores, from several perspectives, the major issues related to VFC accountability. The two major accountability systems under consideration, benchmarking and vaccine replacement, are reviewed and analyzed for their potential accuracy, their effects on physician office practice, and their impact on the entire VFC program.

Trends in the rural-urban distribution of general pediatricians.

OBJECTIVE: A major objective of national and state health policy has been to increase primary care physician supply in rural areas. It is not known whether this objective has been met for general pediatricians. This study examines trends in the rural-urban distribution of general pediatricians in the United States from 1981 to 1996. DESIGN: Descriptive serial cross-sectional study. PARTICIPANTS: At selected 5-year intervals, all clinically active general pediatricians in the United States listed in the American Medical Association Physician Masterfile. MAIN OUTCOME MEASURES: The proportion of pediatricians practicing in rural counties and the ratio of pediatricians to the child population (per 100 000 children <18 years old) for US counties. RESULTS: Between 1981 and 1996, the total number of general pediatricians increased from 19 739 to 34 100. However, rural pediatrician-to-child population ratios (PCPRs) remained well below urban ratios. Although rural counties of all population sizes experienced some gains over time, only those over 25 000 populations had a meaningful increase in their PCPR. Overall, the urban PCPR increased by 14.0 (or an additional pediatrician for every 7150 children) whereas the rural ratio only increased by 4.1 (an additional pediatrician for every 24 400 children). The percentage of recent residency graduates opting for rural practice declined by half (14.6% to 7.4%) over the 15-year study period. Women and international graduates were consistently less likely to practice in rural counties than were men and US graduates, respectively. CONCLUSIONS: The near doubling in general pediatrician numbers from 1981 to 1996 yielded only a modest increase in pediatrician availability for rural children. The discrepancy between urban and rural pediatrician supply increased during this period and should continue growing based on the increasingly urban location of recent residency graduates and the continued growth of women in pediatrics. New policy strategies are needed to improve rural pediatrician availability, including focusing on larger rural counties and addressing barriers to rural practice for women. pediatrics/manpower, pediatrics/trends, rural health, physicians/supply and distribution, medically underserved area.
