This study analyzes the 1993 National Directory of HMOs to determine the extent to which rural counties are included in health
maintenance organization (HMO) service areas. Two specific questions are addressed: (1) How do the patterns of service areas
differ across HMO model types? (2) What are the characteristics that distinguish rural counties served by HMOs from those
that are not? Although a majority of rural counties are in HMO service areas, substantially fewer are served by non-individual
practice association (non-IPA) models. Access to HMO services is found to decrease with county population density, and adjacency
to metropolitan areas is an important predictor of inclusion in service areas.
