Health status, socioeconomic status and utilization of outpatient services for members of a prepaid group practice.
When evaluating the effectiveness of medical care programs, one concern is whether receipt of care is based upon health care needs or upon socioeconomic status. This study describes the relation between health status and socioeconomic status and attempts to determine which has the greater effect on ambulatory care utilization. The study setting was an operating HMO serving a cross-sectional membership of nearly 200,000 persons. Outpatient utilization data were derived from the medical records of a five per cent sample of health plan members for 1969 and 1970. Social, economic, situational, and attitudinal data were provided by 2,603 respondents in a household interview survey. Since a population's perceived health status may reflect health need, information from the survey provided measures of health status that ranged from specific symptoms and complaints to a general measure of perceived health status. Although the findings varied somewhat according to which variables were considered, they generally showed health status to correlate more highly than socioeconomic factors with the utilization of services in this medical care system. An exception was the use of preventive services, which was not significantly related to health status measures but rather, for women, to education and, to a lesser extent, income.
