Abstract
This article compares patterns of health care utilization for hospitalizations and ambulatory care in a sample of 1855 urban, elderly, community residents who report obtaining their health care from one of four types of arrangements: a fee-for-service (FFS) physician, a hospital-based health maintenance organization, a network model HMO, or a preferred provider organization (PPO). Utilization rates reported by respondents at six month intervals over three years were adjusted for health and socioeconomic characteristics of enrollees. PPO plan members consistently have mean and total lengths of hospital stay one-third to one-half those of the others. Although rates of use of particular categories of ambulatory care vary across systems of care, total ambulatory care rates are highest for network model HMO plan members. Specific features of alternative delivery systems, rather than general model types, may have an impact on utilization rates and the costs of care.
