Objective
This study aimed to assess the relationship between neighbourhood-level opioid prescription rates and opioid-related mortality amongst individuals without an opioid prescription.
Findings/Key points
There was no significant association between the total volume of opioid prescriptions dispensed in a dissemination area and opioid-related mortality. In sub-group analyses stratifying the cohort into prescription and non-prescription opioid related mortality, the amount of prescriptions dispensed was positively associated with prescription opioid related mortality. There was also a significant inverse association between increased total volume of opioids dispensed and non-prescription opioid mortality.
Design/methods
Nested case-control study using data in Ontario from 2013-2019. After matching, there were 2,401 cases and 8,813 controls.
