Emergency department utilization, hospital admissions, and physician visits among elderly African American persons.

This study uses a theoretical model of health services utilization to examine (a) emergency department utilization, (b) hospital admissions, and (c) office-based physician visits among a sample of 998 low-income elderly African American persons. Poisson Regression analysis was used to estimate the parameters specified in the Andersen behavioral model. Some of the more interesting results include the following: (a) a greater frequency of emergency room visits among respondents with a lower level of accessibility to physician services, (b) a lack of a significant relationship between some chronic illnesses such as diabetes and heart problems and the frequency of office-based physician visits, (c) a greater number of hospital admissions among insured persons, and (d) a significant impact of the health locus of control indexes on all three types of health care utilization. The results of this study challenge the assumption that hospital and emergency use are the results of nondiscretionary behavior.
