We sought to investigate non-fatal overdose experiences and responses to overdose among a community-recruited sample of injection drug users IDU in Bangkok Thailand. Methods Data for these analyses came from IDU participating in the Mit Sampan Community Research Project. The primary outcome of interest was a self-reported history of non-fatal overdose. We calculated the prevalence of past overdose and estimated its relationship with individual drug-using social and structural factors using multivariate logistic regression. We also assessed the prevalence of ever witnessing an overdose and patterns of response to overdose. Results These analyses included 252 individuals their median age was years IQR - and 66 were female. A history of non-fatal overdose was reported by 75 participants. In a multivariate model reporting a history of overdose was independently associated with a history of incarceration Adjusted Odds Ratio AOR 95 Confidence Interval CI - p and reporting use of drugs in combination AOR 95 CI - p . A majority reported a history of witnessing an overdose most reported responding to the most recent overdose using first aid . Conclusions Experiencing and witnessing an overdose were common in this sample of Thai IDU. These findings support the need for increased provision of evidence-based responses to overdose including peer-based overdose interventions. Background Accidental .
