Utilization of medical services by alcoholics participating in a health maintenance organization outpatient treatment program: three-year follow-up.
IN a cumulative 3-yr follow-up study of utilization of medical services by alcoholics participating in a health insurance maintenance organization (HMO) outpatient alcoholism treatment program, expenditures of 59 alcoholics were compared with those of 78 alcoholics who chose not to participate. Results show significant differences in dollar cost per patient per year between groups in inpatient expenditures (p = 0.03). When alcoholism clinic costs were excluded from combined inpatient and outpatient expenditures, significance was maintained over the 3 yr (p = 0.02). In combined inpatient and outpatient expenditures including alcoholism treatment costs, the dollar differential between groups was substantial but not statistically significant.
