National health data for policy and planning.
The role of the National Center for Health Statistics (NCHS) in providing data for health policy and planning at the national and local level is discussed. Four specific examples are considered. First, data from the Hospital Discharge Survey are used to identify surgical procedures with large increases between 1965 and 1976: 30 percent rise in the incidence of hysterectomy, 169 percent increase in cesarean section, 100 percent increase in lens extraction, and 35 percent increase in orthopedic surgery. The extent to which such increases represent unnecessary utilization and their impact on costs are discussed. Second, the combination of data from two sources (Health Interview Survey and Health and Nutrition Examination Survey) is illustrated by considering selected policy issues related to hypertension. Next, the problem of designating medically underserved areas is discussed in relation to the difficulties in implementing federal policies at the local level without local data. The potential for national data systems to provide guidance for these policies is also considered. The final example discusses the use of vital statistics to provide small area data for local health planning. In conclusion several areas are considered which need development in order to maximize the use of data for policy and planning: research on measurement of health status, with particular emphasis on how health policy can affect health status; research on appropriate levels of health resources and services; development of shared data systems to reduce cost and respondent burden; and training, especially at the undergraduate level and in interdisciplinary graduate programs.
