The cost-effectiveness of long-term post-treatment peer recovery support services in the United States.

Peer recovery support services (PRSS) have been widely adopted across a variety of settings, but little is known about their economic impact. To conduct a cost-effectiveness analysis of long-term, PRSS delivered after specialty substance use disorder (SUD) treatment (post-treatment), and to describe the development of a free, web-based cost-effectiveness calculator based on this analysis. Using publicly available data from a variety of sources, post-treatment PRSS were compared to specialty SUD treatment from the societal (broad perspective including costs like participant time) and health systems perspectives (only costs borne by health system), and in terms of quality-adjusted life years (QALYs) added and people in recovery.
