摘要: Enrollment decisions of a sample an employed population choosing among open-panel and closed-panel HMOs Blue Cross/Blue Shield are analyzed. This report, unlike previous ones, overcomes some the difficulties bivariate analysis by use multivariate logistic probability model, logit. The results show that there four consistent predictors enrollment choice: source care as measure access; family life stage chronic conditions per member indicators health risk; capita income economic vulnerability; concern. Having private physician is best single predictor, its absence predicting higher in closed, presence HMO. Higher risk families, younger with more children, likely to join plan than closed or retain BC/BS; incomes larger numbers appear have same effects. levels concern, on other hand, predict greater plan. any HMO predicted 50 cent accuracy for 60 sample. Choice between open plans excess 80 cent, 90 over 10 potential enrollees. applicability this approach feasibility planning clearly indicated.
