University of Michigan·observational·Posted Mar 18, 2021·Updated Mar 18, 2021

In Brief

An observational study evaluating Retrospective analysis of opioid use after surgery for Opioid Use. Completed, enrolled 30,000 participants across 1 site.

Detailed 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.
