Relationship between inpatient alcoholism treatment and longitudinal changes in health care utilization

Abstract

Objective: The purpose of the study was to evaluate changes in health care utilization associated with inpatient alcoholism treatment in alcoholics of low socioeconomic status with different histories of treatment relapse.

Method: The sample consisted of more than 85,000 male alcoholics using inpatient care in Department of Veterans Affairs medical centers in fiscal year 1987. Five treatment groups were identified to represent a continuum of length and intensity of alcoholism treatment, including formal inpatient alcoholism treatment, short detoxification and hospitalizations for primary diagnoses other than alcoholism. All inpatient and outpatient health services for 3 years before and 3 years after the index hospitalization were examined for differential changes in utilization associated with the five treatment groups after controlling for patient predisposing, enabling and need characteristics.

Results: Both total inpatient days and outpatient visits increased significantly for all treatment groups, with the greatest increases occurring in the group completing inpatient alcoholism treatment (both p < .0001). However, use of inpatient medical care decreased and substance abuse inpatient care increased significantly for most groups, with the largest increases in substance abuse care found for the completed treatment group.

Conclusions: In a hospital system that does not deny care on the basis of ability to pay, certain groups of chronic alcoholics who cannot sustain prolonged remission will continue to be heavy utilizers of services. Alcoholism treatment may be associated with higher short-term costs but it remains to be seen whether provision of more focused treatment services is able to achieve longer term better outcomes and, ultimately, lower costs.
