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 …

Prediction Of Pneumonia In Outpatients With Acute Cough - A Statistical Approach, Paula Diehr

Cough is the fifth most common reason for physician visits, but data on acute cough have rarely been collected in a standardized manner and have not been analyzed in a multivariate fashion. We report data on 1819 patients presenting with cough, all of whom received a standardized history and physical, and a chest X-ray. Only 48 (2.6%) were found to have an acute radiographic infiltrate (pneumonia). The prevalence of common signs and symptoms is shown for the patients with and without pneumonia. Thirty-two of these findings were significant predictors of pneumonia (p less than 0.05, one-tailed). These 32 did not …

Use Of Ambulatory Care Services In Three Provider Plans: Interactions Between Patient Characteristics And Plans, Paula Diehr

A previous study of low-income enrollees in a closed-panel health maintenance organization (HMO) and a Blue Cross/Blue Shield (BC/BS) plan showed that the effect on the use of health services of the age, sex, health status, previous health care use, race, and family size of the enrollees was different in the two plans. We have replicated this study using the same two provider plans but studying a different group of white collar, middle class enrollees. A third plan, an experimental independent practice association (IPA), was also available for analysis. Utilization was defined as use (yes/no) and the quantity of use …
