Ambulatory medical care -- Florida, Health maintenance organizations -- Florida
The utilization of ambulatory services by the health maintenance organization of Florida (HMO), independent practice association (IPA) model, was compared to a fee-for-service population. Each randomly selected group consisted of 250 patients being cared for by the same providers, at the same clinic, during the calendar year 1986. Demographic and clinical data was gathered from the office charts. Frequencies were evaluated by the Statistical Package for the Social Sciences and t-tests were run to substantiate variance at the 0.05 level of confidence. The HMO group is a younger population (t=0.017), and the males are responsible for the increased utilization of ambulatory services (t-0.001). Trends of increased utilization are noted across the age groups and the variables. The rate of hospitalization is insignificantly higher for the HMO population and covers a broader range of age groups. Consequently, this HMO IPA model increases the rate of ambulatory service utilization in a younger population without reducing the rate of hospitalization. Cost effectiveness studies and organizational management evaluations are needed.
