Clinical Outcomes of the First 2 Years of Implementation of the Integrated Care Pathway for Concurrent Major Depressive Disorder and Alcohol Use Disorder

BackgroundBoth major depressive disorder (MDD) and alcohol use disorder are highly prevalent, often comorbid and cause significant socioeconomic burden. At CAMH, we have developed and integrated care pathway (ICP) to treat these disorders and evaluated its effectiveness in comparison to treatment as usual (TAU)MethodsChart review; descriptive statistics, c2 and t-tests, linear mixed effects models, Kaplan–Meier and log-rank analyses.ResultsOverall, 81 patients were enrolled into ICP. Comparisons of treatment retention rates between ICP patients and matched historical controls (n = 81) showed significantly lower dropout rate in ICP cohort (18.5% vs. 69.1%, P < 0.001, Fig. 1). The ICP patients demonstrated significant reduction in depressive symptoms severity (QIDS: 14.6 vs. 10.0, P < 0.001; BDI 26.3 vs. 16.2, P < 0.001), reduction in the amount of alcohol consumed weekly from 44.6 standard drinks at baseline to 12.6 (P < 0.001) by the end of treatment, which was significantly better compared to controls (56.9 vs. 25.2, P < 0.001), P = 0.014 (Fig. 2).ConclusionsThe ICP is a feasible approach to treatment of concurrent AUD and MDD with significantly higher retention rates than TAU. Patients demonstrate improvements on several levels including depressive symptoms, and changes in alcohol drinking patterns.Disclosure of interestThe authors have not supplied their declaration of competing interest.
