Study Summary
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.
Primary Outcome
Among patients who undergo surgery, new persistent opioid use is defined as filling an opioid prescription in post-discharge days 4-90 and filling another opioid prescription in post-discharge days 91-180. This incidence will be measured from 1/1/13-6/30/16 (before M-OPEN established) and from 7/1/16-12/31/19 (after M-OPEN established) and the change before and after this date will be compared between Michigan and all other states (the difference-in-differences). Outcomes will be measured at 1 y
