Utilization patterns of health maintenance organization disenrollees. 1984

M J Griffith, and N Baloff, and E L Spitznagel

This article addresses several questions about the effect of disenrollment on the start-up phenomenon in health maintenance organizations that were raised in a recent exchange of articles and comments in this journal. The results show that disenrollees, like continuous enrollees, go through a start-up phase of utilization that decreases over duration of membership to a stable lower level. The study also differentiates between voluntary and involuntary disenrollees, both of which go through start-ups. The different characteristics of the start-ups of both groups of disenrollees are contrasted with those of continuous enrollees. The implications of these findings for planners and administrators are discussed, and a future research agenda is recommended.

D012044 Regression Analysis Procedures for finding the mathematical function which best describes the relationship between a dependent variable and one or more independent variables. In linear regression (see LINEAR MODELS) the relationship is constrained to be a straight line and LEAST-SQUARES ANALYSIS is used to determine the best fit. In logistic regression (see LOGISTIC MODELS) the dependent variable is qualitative rather than continuously variable and LIKELIHOOD FUNCTIONS are used to find the best relationship. In multiple regression, the dependent variable is considered to depend on more than a single independent variable.
