Reactions of pediatricians to a new Centers for Disease Control recommendation for universal immunization of infants with hepatitis B vaccine.

Despite immunization programs targeting high-risk groups, the incidence of hepatitis B has risen 37% over the last decade with 300,000 new infections and 5000 related deaths now occurring annually in the United States. As a new strategy to control the spread of hepatitis B, the Advisory Committee on Immunization Practices of the Centers for Disease Control (CDC) recommended in November 1991 universal hepatitis B immunization of infants. Details were published in an addendum to Morbidity and Mortality Weekly Report. There was no other federal effort to disseminate this recommendation. On February 14, 1992, the American Academy of Pediatrics (AAP) issued a similar recommendation. The time between the CDC and AAP recommendations presented the opportunity to determine the singular effect on clinical practice of the CDC's dissemination effort. The purpose of this study was to assess (1) the effectiveness of the CDC in disseminating a new immunization recommendation, (2) the effect of the new recommendation on clinical practice, and (3) the degree to which noneconomic barriers may affect adoption of universal hepatitis B immunization. All 778 pediatricians in North Carolina were surveyed by mail 2 to 3 months after publication of the new CDC recommendation. Descriptive statistics, chi 2 analysis, and logistic regression were used to assess the relationship of variables hypothesized to predict physician awareness of and/or agreement with the new recommendation. The response rate was 78%. Although 82% of pediatricians who administer immunizations were aware of the new recommendation, only 32% believed it was warranted in their practices.(ABSTRACT TRUNCATED AT 250 WORDS)

Family physician acceptance of universal hepatitis B immunization of infants.

BACKGROUND: The incidence of hepatitis B infection has risen 37% over the last decade; 300,000 new infections and 5000 deaths occur annually in the United States. Because immunization programs that targeted high-risk groups failed to abate this increase, the Centers for Disease Control (CDC) recommended in November 1991 universal hepatitis B immunization of infants. Details were published in an addendum to Morbidity and Mortality Weekly Report. The purpose of this study was to assess (1) the effectiveness of the CDC in disseminating a new immunization recommendation to family physicians, (2) the effect of the new recommendation on clinical practice, and (3) the degree to which noneconomic barriers may affect adoption of universal hepatitis B immunization. METHODS: A random sample of 300 family physicians in North Carolina was surveyed by mail. Descriptive statistics and chi-square analysis were used to assess the relationship of variables hypothesized to predict physician awareness of, and agreement with, the new recommendation. RESULTS: The response rate was 78%. Overall, 48% of family physicians who administered immunizations to children were aware of the new hepatitis B vaccine recommendation. However, only 17% agreed that it was warranted for all newborns in their practice. Twenty-five percent expected more than one half of the parents to refuse three injections at a single well-child visit, a result of adding this vaccine to the current primary immunization schedule. Additionally, 42% expected nurses to resist giving three injections at one visit. CONCLUSIONS: The CDC does not have an effective mechanism for disseminating information to all physicians who care for children. Improved coordination of recommendations between the CDC and relevant specialty societies may help to increase physician adoption of new immunization recommendations in their clinical practice. Additionally, practical concerns of physicians and their patients regarding multiple injections and other practice-relevant issues must be considered when formulating new immunization recommendations, if their implementation is to be successful. Additional research is needed to determine effective methods to disseminate immunization information and to address practical concerns of clinicians.

From activated patient to pacified activist: a study of the self-care movement in the United States.

Self-care education programs in operation in the United States during the mid-1980s are surveyed by mailed questionnaire to determine the nature and content of the curricula of these programs, their organizational sponsorship, the level and types of staff working in them, and their principal prevention emphases. Results indicate that over 75% of these programs offer instruction or sponsored activities intended to help individuals or their families to: (1) increase wellness or health status through lifestyle change; (2) reduce an established risk factor; and/or (3) prevent the onset of illness or injury. Fifty-five percent of the organizations offering these services classified themselves as health services delivery organizations. A surprising finding, given the American popular media treatment of self-care as a 'movement', is that relatively few laypersons function as instructors in these programs. The paper describes the way in which self-care has been absorbed into the mainstream of American health care, even though the concept of self-care has tended to drop from scholarly attention in the socio-medical sciences in the United States.

A survey of smoking and quitting patterns among black Americans.

A sample of adult Black policyholders of the nation's largest Black-owned life insurance company was surveyed in 1986 to add to limited data on smoking and quitting patterns among Black Americans, and to provide direction for cessation initiatives targeted to Black smokers. Forty per cent of 2,958 age-eligible policyholders for whom current addresses were available returned a completed questionnaire. Population estimates for smoking status agree closely with national estimates for Blacks age 21-60 years: 50 per cent never-smokers; 36 per cent current smokers; 14 per cent ex-smokers. Current and ex-smokers reported a modal low-rate/high nicotine menthol smoking pattern. Current smokers reported a mean of 3.8 serious quit attempts, a strong desire and intention to quit smoking, and limited past use of effective quit smoking treatments and self-help resources. Correlates of motivation to quit smoking were similar to those found among smokers in the general population, including smoking-related illnesses and medical advice to quit smoking, previous quit attempts, beliefs in smoking-related health harms/quitting benefits, and expected social support for quitting. Methodological limitations and implications for the design of needed Black-focused quit smoking initiatives are discussed.

Large medical group-practice organizations and employed physicians: a relationship in transition.

Out of the revolution in medical practice is being forged a new type of group-practice organization--larger and more complex, more tightly administered, and more strategically aware than its antecedents. A typology is offered to contribute to an understanding of the changing physician/group-practice relationship. Drawing upon historical and contemporary literature, initial and following-up field observations, and extensive interviews, large medical group-practice organizations are analyzed according to basic orientation toward the health care market, and to a belief in how medical practice should be organized. The revolution in practice will be stamped on future health care arrangements, and will be transmitted into the professional culture of medicine.

An evaluation of subsidized rural primary care programs: I. A typology of practice organizations.

The design of a comprehensive evaluation of subsidized rural primary care programs on a large national scale is described, Its major purpose is to derive data whose analysis will answer major policy questions about the factors influencing the outcome of the major types of such programs in different communities. This first paper also delineates a typology which was developed of five principal organizational forms of these programs. This classification appears to provide suitable operational definitions of forms of rural practice as a basis for evaluating the differential impact of alternative types of primary care programs.

An evaluation of subsidized rural primary care programs: II. The environmental contexts.

The placement of subsidized primary care programs in rural communities has been an important aspect of national health policy over the last decade. Using survey and secondary data from programs in over 700 counties in the United States, it was found that while about one-fourth of all counties with some rural populations have been affected by these programs, certain environmental factors are associated with more or less likelihood of placement. High levels of need and low levels of health care resources are positively associated with the presence of a program. States with health policy climates supportive of reimbursement and broader staffing of primary care programs also contained programs in a higher proportion of their rural counties. The effects of decreased federal funding, increased state responsibility, and the precarious market conditions for primary care programs are discussed with emphasis on the mechanisms for developing favorable climates for these programs.

Estimating dental manpower requirements on a statewide basis.

The North Carolina Dental Manpower Study undertook to use epidemiological data on dental disease, data on practice productivity, and estimates of treatment needs to arrive at more useful measures of dental manpower requirements on a statewide and substate regional basis. As in all attempts to plan for health manpower, the North Carolina study relied upon a measure of subjective judgment pertaining to the treatment/services required to deal with certain dental conditions. These judgments, however, were representative of the conventional standards of practice in North Carolina at the time of the study. Though certain important factors necessary to a complete assessment of dental manpower requirements were not directly measured in the study (e.g., consumer demand), estimates of the volume increase in dental-office practice-productivity were derived for the major categories of dental procedures and conditions. In North Carolina this technic is thought to represent a more meaningful approach to dental manpower planning than the conventional manpower-to-population ratio.

Practitioner self-confidence and patient outcomes in acute low back pain.

OBJECTIVE: To compare outcomes for patients with acute low back pain who received care from practitioners with different self-confidence scores on a 4-item scale. DESIGN: Cross-sectional survey of practitioners. Prospective cohort study of patient outcomes. SETTING: Private practices and a group model health maintenance organization. PARTICIPANTS: One hundred eighty-nine practitioners, including private practice traditionally trained medical physicians, chiropractors, and physicians in a group model health maintenance organization, who were randomly chosen from practices across the state of North Carolina. These practitioners enrolled 1633 patients with acute low back pain into a prospective cohort study. METHODS: The practitioner survey contained 10 questionnaire items that measured aspects of practitioner confidence and attitudes in assessing and treating patients with low back pain. Patients were interviewed by telephone after the initial office visit and at 2, 4, 8, 12, and 24 weeks, or until complete recovery, whichever came first. RESULTS: Of 189 study practitioners, 95% responded to the survey. A 4-item scale, shown by factor analysis to describe practitioners' self-confidence, demonstrated good internal consistency among physicians and chiropractors. Chiropractors had significantly stronger self-confidence scores than physicians. Among patients of primary care physicians and chiropractors, those who received care from practitioners with stronger self-confidence scores did not differ in the time to functional improvement, overall patient satisfaction, or their perception of the completeness of care. CONCLUSION: The level of practitioner self-confidence, as measured by a 4-item scale, did not predict patient outcomes in the treatment of acute low back pain.

The comparative retention of National Health Service Corps and other rural physicians. Results of a 9-year follow-up study.

OBJECTIVE: To contrast the retention of physicians serving National Health Service Corps (NHSC) Scholarship Program obligations in rural settings to that of non-NHSC physicians working in the same or similar practices, and to identify promising retention-enhancing strategies. DESIGN: Cohort study. PARTICIPANTS: Four hundred twelve primary care physicians initially identified during an earlier study as working in a national stratified random sample of 178 externally subsidized rural clinics in 1981. Thirty-six percent were serving obligations to the NHSC, nearly all through the NHSC's Scholarship Program. The NHSC and non-NHSC inception cohorts (those first coming to their 1981 [or "index"] practices from May 1979 through December 1981) were created from within the entire group for use in most analyses. INTERVENTION: In 1990, physicians were resurveyed to learn of their backgrounds, experiences in their index practices, and their subsequent career moves. RESULTS: By 1984 and in each year thereafter, fewer NHSC than non-NHSC physicians of the entire respondent cohort remained (1) in their index practices, (2) in their index communities, and (3) in practice in any rural county (P less than .001). In the inception cohort, fewer NHSC than non-NHSC physicians were retained within all three settings by the third year after their initial dates of employment (P less than or equal to .01). After 8 years of employment, group retention rates for NHSC and non-NHSC inception cohort physicians were 12% vs 39% in the index practice and 29% vs 52% in nonmetropolitan practice. Physicians in both NHSC and non-NHSC groups who left their index practices generally left rural practice altogether. CONCLUSIONS: When compared to non-NHSC physicians working in comparable rural settings, the retention of rural NHSC physicians is seen to be poor and only partially explained by fixed physician, practice, or community variables. Long-term retention of NHSC providers is now receiving much needed attention at the federal level.

A rural-urban comparative study of nonphysician providers in community and migrant health centers.

This is a study of the employment of nonphysician providers--nurse practitioners, physician assistants, and certified nurse midwives--in both rural and urban Community and Migrant Health Centers and of factors associated with their employment, based on a 1991 national survey of 383 Centers. Results of the survey suggest that nonphysician providers, in particular nurse practitioners and certified nurse midwives, primarily serve as physician substitutes, and are more likely to be employed by Centers that are larger and have affiliations with nonphysician provider training programs. Rural or urban location is not significantly related to the employment of nonphysician providers after controlling for center size. The fact that rural centers employ fewer nonphysician providers than urban centers can primarily be accounted for by their relatively small size, rather than a lack of interest. These findings demonstrate that the use of nonphysician providers is an important way both to achieve cost containment and improve access to primary care for those residing in medically underserved areas.
