Characterising opioid overdose and mortality in cohorts of people who use drugs

This thesis advances the evidence base on risk and protective factors of opioid overdose and current approaches to reduce the risk of opioid overdose among cohorts of people who use drugs in Australia and Canada. Findings highlight how factors relating to social and environmental disadvantage, use of health services and individual level characteristics relate to overdose risk. This highlights key touchpoints in health and social systems for overdose prevention training. A range of on-the-ground outcomes informed by findings from this thesis are underway.
