Treatment outcome of alcohol use disorder outpatients with or without medically assisted detoxification

Little is known about the incremental effects of medically assisted detoxification on outpatient treatment for alcohol use disorders. The objective of this study was to compare drinking outcomes in a psychosocial treatment program between two groups of heavy drinking patients who had an alcohol use disorder: (a) one group with initial medically assisted detoxification and (b) a second group without initial medically assisted detoxification.

Analyses were conducted on 262 patients with a more severe alcohol use disorder who completed both an intake assessment and a 9-month follow-up assessment. The effect of medically assisted detoxification was determined using logistic regression analysis with a propensity score to control for possible baseline differences between the two groups.

Of the 262 patients, 82 (31.3%) received medically assisted detoxification. These patients were more likely to abstain from alcohol than those without medically assisted detoxification. Abstinence rates in the month before follow-up were 32.9% and 18.9%, respectively (ORadj = 3.48, p = .01, number needed to treat = 7.1).

Medically assisted detoxification may add to the effects of outpatient psychosocial treatment for heavy drinking patients with an alcohol use disorder.
