PURPOSE: To describe data sources and functional utility of the American Association for Pediatric Ophthalmology and Strabismus (AAPOS) workforce database and associated map files. METHODS: Population data from the 2000 U.S. Census and current listings from the AAPOS and American Academy of Ophthalmology (AAO) databases were organized to demonstrate and analyze practitioner-to-population relationships for metropolitan statistical areas nationwide. An interactive map was developed to provide an intuitive graphical display of the data. RESULTS: A total of 749 active AAPOS members were distributed in 154 of 280 defined metropolitan statistical areas. Within these areas, a 0- to 20-year age subgroup varied from 17.8% to 42.6%, with an average of 30.4%. The AAPOS member-to-million-person ratio varied from 1.3 to 27, with higher numbers generally representing regions with population bases inadequately defined by Census Bureau statistical area definitions. Ratios for a majority of larger, better-defined areas ranged from 3 to 4 AAPOS members per million persons. Sizable areas with no AAPOS member presence were identified and tabulated. AAO members with a specified pediatric practice focus who were not AAPOS members were identified in 103 areas, possibly influencing patient choices and practitioner referrals for these regions. CONCLUSIONS: The AAPOS workforce database and related interactive map display practitioner and population data that may assist physicians and planners in targeting practice development and identifying potentially underserved areas. 相似文献

The purpose of this article is to review conceptual/theoretical and review/agenda setting nursing literature on the health care of racial/ethnic minority men [specifically African American/Black, Hispanic/Latino, American Indian/Alaskan Native and Asian/Pacific Islander men] in one of the four targeted areas of health disparities. CINAHL and MEDLINE computer databases were searched from 1983 to the present using a combination of manual and computer-based methods to identify the nursing literature that included any racial/ethnic men in the sample and addressed at least one of the four areas of health disparities targeted by Department of Health and Human Services (DHHS) that affect adults: heart disease, malignant neoplasms (cancer), diabetes mellitus and Human Immunodeficiency Virus (HIV)/AIDS. This review provides an overview of health disparities experienced by racial/ethnic minority men in the targeted areas and of the types of conceptual and agenda-setting articles published in scholarly nursing literature in those targeted areas. 相似文献
