A Difference-In-Differences Analysis of New Persistent Opioid Use After Surgery
Completed
Conditions studied: Opioid Use
In brief
The Michigan Opioid Prescribing and Engagement Network (M-OPEN) was established in 2016 with the goal of reducing excessive opioid prescribing after surgery using evidence-based prescribing guidelines. Beginning in July 2016, M-OPEN began a statewide quality improvement campaign to educate providers and share prescribing best practices. This retrospective study examines the effect of these efforts on new persistent opioid use after surgery compared to other states where no such program existed using a difference-in-differences approach.
