Translation of Legislation: Effect Analysis of Michigan Opioid Law on Clinical Practice
The Annals of thoracic surgery(2022)
Abstract
BACKGROUND To combat almost 450,000 Americans dying of opioid overdose between 1999 and 2018, the Michigan Opioid Laws were implemented on July 1, 2018, to reduce overprescription of opioids. This retrospective study eval-uated the effect of this legislation on prescribing patterns after thoracic operations at an academic, tertiary care center.METHOD Charts of 776 patients undergoing lobectomy, paraesophageal hiatal hernia repair, Nissen fundoplication, or esophagectomy between July 1, 2017, and July 1, 2019, were reviewed. Populations were identified before and after the July 1, 2018 implementation of the Michigan Opioid Laws. Procedure type, analgesic type, total pills, morphine equivalents, and refills and their pill number were independent variables. Patients using opioids for >30 days before operations were excluded.RESULTS Overall, 629 patients were included in the analysis (324 pre-legislation patients, 305 post-legislation patients). The average number of opioids prescribed to patients at discharge before the legislation was 28.0 pills vs 21.4 pills after (P < .01). Before implementation of the Michigan Opioid Laws, 14.5% of patients received refills, whereas only 5.9% received refills after implementation, reducing the average number of refills per patient from 0.19 to 0.07 (P < .001). Average morphine equivalents and percentage of patients receiving opioids showed no statistical difference.CONCLUSIONS The implementation of the Michigan Opioid Laws correlated with a change in clinical practice, potentially by reducing the number of pills and refills prescribed per patient, and did not deter providers from prescribing opioids acutely. This suggests that the Michigan Opioid Laws allow prescribing freedom while giving legislative structure encouraging time-conscious tapering. The Michigan Opioid Laws may serve as a model for other states to emulate.(Ann Thorac Surg 2022;114:2016-22)(c) 2022 by The Society of Thoracic Surgeons
