Description
Summary:To determine the degree to which enrollees of the Greater Marshfield Community Health Plan were representative of the community the plan was designed to serve, a telephone survey of 1,838 households in the 30-township area was undertaken. The response rate was 93%, and data were obtained from 1,718 households containing 5,260 persons. Of these, 484 households had at least one health plan member. Since the plan accepts only persons under age 65, analysis of the data was limited to those persons aged 64 and younger. Results indicate that enrollees showed good representation of demographic variables such as age, sex, and relationship to the household head when they were compared to the under 65 population of the area. When the enrollee's socioeconomic characteristics (education, income, and occupation) were studied, it was found that, although enrollees showed good representation for most categories they tended to underrepresent the under 65 area population in the lowest income and education classes, as well as in the semiskilled or unskilled occupations. The opposite was true for the upper income and educational classes. Data on location of residence indicated that a strong relationship existed between enrollment and proximity to Marshfield, where the major health care center is located. The use of health services was found to be positively related to membership, with enrollees overrepresented among those with recent hospital or physician contacts. The ability to obtain coverage through employment or by other means was found not to be related to membership. Satisfaction as expressed by participants was much higher in the prepaid program than among those with other forms of coverage.
