The relative contribution of outcome domains in the total economic benefit of addiction interventions: a review of first findings

Abstract

Aims: This paper provides a focused summary of the relative contribution of addiction intervention outcomes to total economic benefit, based upon a compilation of published economic studies from the United States.

Design: The relevant literature was searched extensively, and 11 economic studies were selected for review.

Setting: The selected addiction interventions address both alcohol use/abuse and illicit drug use/abuse and represent various treatment modalities, including a brief physician intervention and long-term residential programs.

Participants: Study participants included community-based drug users, pregnant and/or parenting women, problem drinkers, and criminal offenders.

Measurements: These studies estimated the economic benefits of an addiction intervention(s) in terms of one or more of the following outcome domains: criminal activity, health services utilization, employment earnings, and expenditures on illicit drugs and alcohol.

Findings: The primary finding of this review was that avoided criminal activity was the greatest economic benefit of addiction interventions and contributed more, as a separate outcome domain, to the total economic benefit of addiction interventions than any other outcome domain. Reduced utilization of health care services was also a noteworthy economic benefit of addiction interventions.

Conclusions: This study provides a detailed exposition of economic benefits estimation and highlights the potential impact of individual outcomes, thus providing a useful resource for substance abuse researchers and administrators as they design and evaluate future interventions.
