Effectiveness of residential treatment services for veterans with substance use disorders: A propensity score matching evaluation.

BACKGROUND: Prior reviews of substance use disorder (SUD) treatment have found mixed support for residential level of care but are limited by methodology problems and the ethical concerns of randomizing patients with severe SUD to lower levels of care. METHODS: The present study is the first to use a large archival SUD residential sample with a matched comparison group and one-year follow-up period to examine the benefits of residential treatment provided to adults clinically assessed as warranting SUD residential care. We used propensity score matching in our sample (N = 6177) of veterans with a SUD who were screened and accepted for Veterans Affairs (VA) SUD residential treatment between January 1st, 2019 and June 30th, 2019. RESULTS: We found evidence that VA SUD residential treatment saves veteran lives with an average 66% all-cause mortality risk reduction during the study period (b = -1.09, exp(b) = 0.34, p <0.001). Medium-to-large residential pre- to post-treatment self-reported mental health and SUD symptom improvements (|SMDrobust| = 0.54-0.93) were sustained by one-year post-screening. These residential treatment improvements were significantly larger than estimated counterfactual outcomes across self-reported SUD and stress disorder symptoms at one-year post-screening (ps <0.001). We found mixed behavioral, service utilization, and other self-reported mental health outcomes. CONCLUSIONS: We conclude that VA SUD residential treatment is an effective level of care for veterans warranting residential care particularly for SUD symptom improvements and reductions in mortality risk.

Measurement-based care in Veterans Health Administration mental health residential treatment.

In 2016, the Veterans Health Administration (VHA) launched the Measurement-Based Care (MBC) in Mental Health Initiative to support the use of patient-reported outcome measures (PROMs) across mental health services to increase veteran engagement and promote collaborative treatment planning. The present study reported on the administrations of PROMs across all residential stays within the VHA's Mental Health Residential Rehabilitation Treatment Programs between October 1, 2018, and September 30, 2019 (N = 29,111). We subsequently explored a subsample of veterans attending substance use residential treatment during the same period who completed the Brief Addiction Monitor-Revised (BAM-R; Cacciola et al., 2013) at admission and discharge (n = 2,886) to determine the feasibility of using MBC data for program evaluation. The rate of residential stays with at least one PROM was 84.49%. We also identified moderate to large treatment effects on the BAM-R from admission to discharge (Robust Cohen's d = .76-1.60). There is frequent use of PROMs in VHA mental health residential treatment programs with exploratory analyses demonstrating significant improvements for veterans in substance use disorder residential treatment. Considerations for the appropriate use of PROMs in the context of MBC are discussed. (PsycInfo Database Record (c) 2023 APA, all rights reserved).
