Dropout Reasons in an Intensive Outpatient Treatment for Substance Use Disorders. Reflections on New Treatment Designs

Abstract

Introduction: There are scarce studies about why patients dropout addiction treatments. Methods: A mixed analysis about data from 55 patients who discontinued an intensive outpatient approach between June 2019 and November 2021 and their responses to a questionnaire were evaluated. Results: The dropout rate was 29.2%, with a median [95% CI] of 113 days [47-255]. Of the total, 40/55 responded to the questionnaire, 12.5% reported an increase in use and 75% were under mental health treatment. The main reason for dropout was personal, related to ambivalence and the perception of not having a problem. Reasons associated with the program approach included global abstinence and group therapy. Conclusions: Admission strategies, diversification of proposals and inclusion of bond therapy could improve the effectiveness of outpatient addiction programs.
