Background:Peer support programs have proliferated over the past decade, building on recovery oriented programming, yet relationships between peer support services and the costs to public programs have not been well described in literature. The purpose of this study is to fill gaps in the literature related to peer support programs and cost: lack of comparison groups, small sample sizes, and the availability of research examining utilization of Medicaid mental health services.
Methods:The study employed a retrospective design with treatment and comparison groups created from three administrative databases. Three ordinary least squares regression models were constructed to predict crisis stabilization cost, psychiatric hospitalization cost, and total Medicaid cost while controlling for other factors. The Chronic Illness and Disability Payment System + Rx was used to control for illness severity.
