Severe alcoholism in the mental health sector: I. A cost analysis of treatment.

In a country in which the public mental health sector provides services to alcoholics, the costs of direct care to alcoholics were compared with those of other mental health patients. Costs were developed for a 1-yr cohort of patients who had received inpatient care but who had recently come from the community and returned to the community. The costs were based on inpatient and outpatient utilization within 2 yr of follow-up, commencing at discharge from inpatient care. Alcoholics represented the largest single diagnostic group in the cohort (39%), although their cost of care was only 22% of total costs. This is so despite the facts that similar percentages of alcoholics and nonalcoholics required rehospitalization in the 2 yr of follow-up and both groups exhibited similar patterns in the number of readmissions. Alcoholics have lower costs than other patients because they use cumulatively fewer inpatient days and receive fewer days of the most expensive outpatient service of full-day treatment. On the average, the cost to serve alcoholic patients is less than half the cost to serve nonalcoholic patients.
