Abstract: Introduction: During treatment for alcohol use disorder (AUD), about 40% of patients return to drinking. Whether the risk of relapse changes during treatment and how relapses may affect the risk of subsequent relapse are unclear, however. The current study, therefore, aims to identify when and with what probability relapses occur. Methods: One hundred and three inpatients at an AUD treatment center participated in this observational study. The study documented relapse to drinking using breath analyzers, urine tests, and self-reported incidents for 42 days after the start of treatment. Time to the first relapse event and to any subsequent relapse event served as the outcome measures. The study determined the proportion of patients who had not experienced a relapse event at any given point by Kaplan-Meier estimates and Cox proportional hazards models. The study team computed the instantaneous probability of experiencing an event at any given point using generalized estimating equation (GEE) models of the binomial family with log-link and exchangeable correlation structure to estimate unadjusted and adjusted hazards. Results: Whereas the hazards of experiencing a first relapse event declined steadily over the 42 days, the hazards of experiencing a subsequent relapse following an initial event remained stable. Both first-time and recurrent relapses were positively associated with the number of DSM-5 AUD criteria. Conclusion: Whereas the risk of relapse declines with each day of abstinence during treatment, it remains high after an individual relapse for the first time. This finding implies that therapy should focus on strengthening selfefficacy for low-risk groups and on relapse-prevention strategies for high-risk groups.
