Factors explaining the use of health care services by the elderly.
The Anderson model of health services utilization, which relates use of service to predisposing, enabling, and need factors, has not often been applied to an elderly population. In this study, the factors of the Andersen model were used prospectively to predict utilization for a population sample of 1,317 elderly persons. Taken alone, the NEED construct was the most important single predictor of use of physician services, hospitalizations, ambulatory care, and home care. PREDISPOSING factors were better predictors of the use of dental services. Some of the variables studied were not related to utilization in the direction that would have been predicted from previous studies on general populations. Multivariate analyses demonstrated that the three constructs should be applied simultaneously when predicting use of services. These findings can be applied to the specific task of planning services for older people.

Toward understanding elders' health service utilization.
Providing appropriate health services to the elderly is emerging as one of the major challenges of this decade. Using the theoretical framework developed by Andersen and Aday, this study attempts to improve our understanding of those factors which inhibit or facilitate elders' use of health services. The data come from a 1974 statewide random probability sample of 1,625 noninstitutionalized elders 65 years of age or older living in Massachusetts. Regression analysis is used to study the effects of predisposing, enabling, and need characteristics on the use of five health services: hospitals, physicians, dentists, home care, and ambulatory care. The model explains from 5% to 27% of the variance in health service utilization. Need characteristics, in general, account for most of the explained variance.
