Abstract
Background: Most addicts relapse in the first year of treatment especially in the first 3 - 6 months, which is the most vulnerable period. Objectives: The present study aimed to assess the predictors of substance abuse slip and relapse among addicts in the first 6 months of treatment with an emphasis on treatment related factors. Methods: The data of this cross-sectional study collected through assessment of 148 patients who were referred to the Methadone/Buprenorphine maintenance therapy clinics of Kermanshah city during April to September of 2015. Demographic, history, treatment checklist, comorbidity index, and medical records were used for collecting data. Data was analyzed through chi-square, t-test, and Binary logistic regression analysis. Results: The mean age of total participants was 42.4 ± 11.3 years and 98% of them were male. 27% and 35.1% of the patients, respectively, had a slip and relapse during the first 6 months of treatment. After adjustment for all demographic data, it was indicated that self-employment (P = 0.037), more treatment costs (P = 0.049), previous treatment history (P = 0.027), not satisfied dose of medication (P = 0.012), and lack of medical therapy history under physicians supervision (P = 0.046) can increase the possibility of a slip significantly. Conclusions: Despite the fact that prevention of re-abuse and relapse of disease includes multi-factorial approach, it seems that the treatment-related factors are as the most major factors in relapse and slip during the first 6 months of treatment. Health practitioners’ special attention to treatment related factors in addiction, especially previous treatment history as the most important predictor of relapse, are probably effective in the control and decrease of a slip and relapse.
