Social and economic characteristics of those experiencing hospitalizations due to opioid poisonings.

Hospitalizations due to opioid poisonings are increasing. While considerable information is available on the demographic and geographic distribution of opioid-related events, national data on the social and economic circumstances of those experiencing these events are limited. This study uses data from the National Household Survey (2011) linked to the Discharge Abstract Database (2011 to 2016) to provide the first national-level estimates of the socio-economic characteristics of individuals experiencing opioid-related hospitalizations. Results reveal elevated hospitalization rates among people who have lower levels of income and education, are unemployed or out of the labour force, identify as Indigenous, live in lone-parent households, and spend more than 50% of their household income on housing. Understanding the circumstances of individuals who experienced adverse opioid events will help inform policies addressing potential determinants.
