Drinking patterns and problems: a comparison of ER patients in an HMO and in the general population.

The purpose of this study was to compare drinking patterns and alcohol-related problems and associations of these variables with casualties in an emergency room (ER) population and in the general population from which these patients come. A probability sample of patients seen in all three health maintenance organization (HMO) hospital ERs in one U.S. county (N = 986) and a household probability sample of those living in the same county who reported belonging to the HMO (N = 735) were interviewed. The ER sample was more likely to report consequences related to drinking, less likely to report feeling they should cut down on their drinking, and more likely to report greater use of the ER than the general population sample. Similar associations were found between injured and noninjured in the two samples. These data lend support for the generalizability of findings of associations of alcohol and casualties obtained from ER studies to the larger general population.
