Risk of non-medical drug overdose following prescription of opioids post-injury: A retrospective cohort study

There has been increasing scrutiny of opioid prescribing following injury given concerns that prescribed opioids may contribute to addiction and/or overdose. This study aimed to better understand the relationship between injury, opioids prescribed pre- and post-injury, and non-medical drug poisoning. Focusing on working age (15-65 years old) residents of the Fraser Health region, this study used a linked administrative dataset to better understand the relationships between injury, whether the injury was work-related or sustained outside of the workplace, pain management medication in the form of opioid and opioid agonist therapy prescriptions before and after injury, and potential non-medical drug poisoning.
