What is the incidence of mortality following emergency department visits for nonfatal opioid overdose?
A cohort study including over 6,000 patients in Ontario, Canada found 5.3% died within one year and 1.9% died of opioid-related causes. Predictors of mortality included male sex, opioid agonist therapy, and benzodiazepine use. Lower risk of death was found in patients seen by a family physician in the preceding 12 months.
