Relapse during opioid use disorder treatment: A pilot study to understand the reasons for opioid use during treatment.

Background: Opioid use is a cause of concern in many parts of the world. About 2.1% Indians use opioids. Opioids are also the most common drugs used by injection drug users in India. Despite various treatment strategies used to manage opioid use disorders (OUDs), relapse is common. A good treatment program would make efforts to address lapses and prevent relapse. Hence, there is a need to understand the factors associated with relapse in OUD. Method: One hundred and twenty patients completed a baseline assessment that included socio-demographic details and the Maudsley Addiction Profile (MAP). They were followed up for three months and assessed using telephonic interview for opioid use. All those who relapsed were assessed using the Reasons for Relapse Questionnaire (RRQ). The patients who relapsed were compared with the patients who were abstinent. Relapse was defined as any use of opioid during follow-up. Results: Forty participants relapsed during the 90 days of the study period. Relapsed patients had a greater number of conflict days with family members, used a higher amount of heroin and cannabis at baseline, were less likely to be discharged on buprenorphine, and were more likely to drop out. Participants cited mood and social reasons more often than cue/craving and unwell domains of RRQ. Conclusion: Baseline treatment and prospective factors are associated with relapse in OUD. Addressing these factors can help in reducing relapse in OUD patients.
