Health department clinics as pediatric immunization providers: a national survey.

OBJECTIVE: To describe a national sample of health department immunization clinics in terms of populations served, patient volume trends, services offered, and immunization practices. METHODS: Telephone survey conducted with health departments sampled from a national database, using probability proportional to population size. RESULTS: All (100%) 166 sampled and eligible clinics completed the survey. The majority of pediatric patients were uninsured (42%) or enrolled in Medicaid (34%). Most children (69%) and adolescents (70%) were referred to the health department, with only 12% using these clinics as a medical home. A number of clinics (72%) reported recent increases in adolescents served. Less than 25% of clinics offered comprehensive care, 47% conducted semiannual coverage assessments, and 76% and 38% operated recall systems for children and adolescents. Storage of records in an electronic database was common (83%). CONCLUSIONS: Although the majority of these clinics do not provide comprehensive care, they continue to serve vulnerable children, including adolescents, Medicaid enrollees, and the uninsured, and may represent the main contact with the healthcare system for such patients. Because assuring the immunization of these children is essential to their health and the health of our nation as a whole, this immunization safety net must be preserved. Experience implementing key recommendations such as coverage assessment and feedback as well as reminder or recall may enable health department staff to assist private provider colleagues. Further research is needed to investigate how patient populations, services offered, and immunization practices vary by different clinic characteristics.

Immunization pockets of need: science and practice.

Despite high overall immunization coverage levels among U.S. preschool children, areas of underimmunization, called pockets of need, remain. These areas, which pose both a personal health and a public health risk, are typically poor, crowded, urban areas in which barriers to immunization are difficult to overcome and health care resources are limited. The purpose of this report is to review barriers to immunization of preschool children living in pockets of need and to discuss current issues in the identification of and implementation of interventions within these areas. The Centers for Disease Control and Prevention administers a federal grants program that funds state and metropolitan immunization programs. This program promotes a three-pronged approach for addressing pockets of need: (1) identification of target areas, (2) selection and implementation of programmatic strategies to improve immunization coverage, and (3) evaluation of progress or impact. At each step, scientific evidence can guide programmatic efforts. While there is evidence that state and metropolitan immunization programs are currently making efforts to address pockets of need, much work remains to be done to improve immunization coverage levels in pockets of need. Public health agencies must take on a broadened role of accountability, new partnerships must be forged, and it may be necessary to strengthen the oversight authority of public health. These tasks will require a concentration and redirection of resources to support the development of an immunization delivery infrastructure capable of ensuring the timely delivery of immunizations to the most vulnerable of America's children.

Vaccines for Children program, United States, 1997.

OBJECTIVES: 1) To determine the proportion of preschool children receiving immunizations from providers enrolled in the Vaccines for Children (VFC) program; 2) to assess whether their immunization providers serve as their medical home for primary care; and 3) to examine the relationship between various provider characteristics and immunization status. DESIGN: Two-phase national survey consisting of parent interviews verified by provider record check. SETTING: A total of 78 survey areas (50 states, the District of Columbia, and 27 urban areas). PATIENTS OR OTHER PARTICIPANTS: Noninstitutionalized children from 19 to 35 months of age in 1997. INTERVENTIONS: None. OUTCOME MEASURES: VFC penetration rate (the percentage of children who received all or some vaccines from a VFC-enrolled provider); the frequency with which children received all or some vaccines within a medical home; the number of parent-reported immunization providers; and 4:3:1:3 up-to-date status at 19 to 35 months of age. RESULTS: OFF 28 298 children interviewed for whom consent to contact providers was obtained, complete provider data were available for 21 522 (76%). Of these children, approximately 75% received all or some immunizations from a VFC-enrolled provider, 73% received all or some immunizations within a medical home, and 75% had one immunization provider. Children received all or some immunizations from a VFC-enrolled provider more frequently when vaccinated by pediatricians versus family physicians or in public facilities versus private practice. After controlling for poverty, immunization coverage varied only slightly with receipt of vaccines from a VFC-enrolled provider, receipt of vaccines within a medical home, and the number of parent-reported providers. Among children vaccinated within a medical home, those vaccinated solely by pediatricians were 1.63 times as likely to be 4:3:1:3 up-to-date than were those vaccinated solely by family physicians after removing the effects of poverty. RECOMMENDATIONS: Greater numbers of children are likely to benefit from an even higher participation rate among immunization providers in the VFC program, particularly among family physicians and private physicians. The public-private collaboration developed by the VFC program should be capitalized on so that public sector resources can help pediatricians and family physicians practice according to the Standards for Pediatric Immunization Practices.

Visual impairment in a rural Appalachian community. Prevalence and causes.

A population-based survey of 1136 subjects aged 40 years and older was conducted in a rural valley of Kentucky to determine the nature and extent of visual disability in an underserved area of rural America. Data on corrected visual acuity and ocular history, along with demographic, socioeconomic, and health care utilization parameters, were gathered. Those subjects with an acuity below 20/60 in either eye underwent a comprehensive ophthalmologic examination. The prevalence of binocular blindness (acuity worse than 20/400 in the better eye) was 0.44% and of monocular blindness (acuity worse than 20/400 in one eye) was 3.3%, approximately twice the national rates. The chief cause of bilateral visual impairment was macular degeneration among men and cataract among women. Cataract, trauma, and amblyopia were the major causes of monocular visual impairment in both sexes. Risk factor analysis revealed younger age, higher education, active employment, access to a health care facility, and comprehensive health insurance coverage to be inversely associated with visual impairment.
