Cost-Effectiveness of Peer-Delivered Interventions For Cocaine and Alcohol Abuse Among Women: A Randomized Controlled Trial

Abstract

Aims: To determine whether the additional interventions to standard care are cost-effective in addressing cocaine and alcohol abuse at 4 months (4 M) and 12 months (12 M) from baseline.

Method: We conducted a cost-effectiveness analysis of a randomized controlled trial with three arms: (1) NIDA’s Standard intervention (SI); (2) SI plus a Well Woman Exam (WWE); and, (3) SI, WWE, plus four Educational Sessions (4ES).

Results: To obtain an additional cocaine abstainer, WWE compared to SI cost $7,223 at 4 M and $3,611 at 12 M. Per additional alcohol abstainer, WWE compared to SI cost $3,611 and $7,223 at 4 M and 12 M, respectively. At 12 M, 4ES was dominated (more costly and less effective) by WWE for abstinence outcomes.

Conclusions: To our knowledge, this is the first cost-effectiveness analysis simultaneously examining cocaine and alcohol abuse in women. Depending on primary outcomes sought and priorities of policy makers, peer-delivered interventions can be a cost-effective way to address the needs of this growing, undeserved population.
