Opioid Prescribing and Opioid-Related Hospital Visits in Ontario

The ODPRN conducted a cross-sectional analysis among individuals aged 15 years and older to evaluate rates of opioid prescribing and opioid toxicity-related hospital and emergency department visits, by county in Ontario.  The results are reported here and are illustrated in the map below.  **Please note: over the past 3 months, the ODPRN has worked with CIHI and CCSA to further refine the definition of opioid toxicity in an attempt to generate a definition that can be used consistently across Canada.  We have therefore revised our earlier report to align with the definition that we developed**

Overall key findings demonstrate:

  • Rates of opioid prescribing and hospital visits related to opioid toxicity have increased across Ontario’s counties between 2006-2010 and 2011-2013 among younger (15-64) and older (65+) individuals.
  • During 2011-2013, there was a 11-fold variation in annualized rates of opioid prescribing and a 7-fold variation in annualized rates of opioid toxicity-related hospital admission between counties.
  • Opioid prescribing rates were found to be higher among younger beneficiaries, however rates of hospitalization and emergency department visits for opioid toxicity were found to be higher among older individuals.
