Abstract
Objective Multiple detoxification admissions among clients with substance use disorders (SUD) are costly to the health care system. This study explored the impact on behavior and cost outcomes of recovery support navigator (RSN) services delivered with and without a contingent incentive intervention. Methods New intakes at four detoxification programs were offered RSN-only (N = 1116) or RSN plus incentive (RSN + I; N = 1551) services. The study used a group-level cross-over design with the intervention in place at each clinic reversed halfway through the enrollment period. RSN + I clients could earn up to $240 in gift cards for accomplishing 12 different recovery-oriented target behaviors. All eligible clients entering the detoxification programs were included in the analyses, regardless of actual service use. Results Among RSN + I clients, 35.5% accessed any RSN services compared to 22.3% in the RSN-only group (p <.01). Of RSN + I clients, 19% earned one, 12% earned two and 18% earned three or more incentives; 51% did not earn any incentives. The majority of incentives earned were for meeting with the RSN either during or after detoxification. Adjusted average monthly health care costs among clients in the RSN-only and RSN + I groups increased at a similar rate over 12 months post-detoxification. Discussion Possible explanations for limited uptake of the incentive program discussed include features of the incentive program itself, navigator-client communication, organizational barriers and navigator bias. The findings provide lessons to consider for future design and implementation of multi-target contingency management interventions in real-world settings.
