BackgroundStates have implemented policies to decrease clinically unnecessary opioid prescribing, but few studies have examined how state policies affect opioid dispensing rate trends for surgical patients.ObjectiveTo examine trends in the perioperative opioid dispensing rates for fee-for-service Medicare beneficiaries and the effects of select state policies.Design And ParticipantsA retrospective cohort study using 2006 to 2018 Medicare claims data for individuals undergoing surgical procedures for which opioid analgesic treatment is common.ExposuresState policies mandating prescription drug monitoring program (PDMP; PDMP policies) use, initial opioid prescription duration limit (duration limit policies), and mandated continuing medical education (CME; CME pain policies) on pain management.Main MeasuresOpioid dispensing rates, days' supply, and the daily morphine milligram equivalent dose (MMED).Key ResultsThe percentage of Medicare beneficiaries dispensed opioids in the perioperative period increased from 2007 to 2018; MMED and days' supply decreased over the same period, with significant variation by age, sex, and race. None of the three state policies affected the likelihood of Medicare beneficiaries being dispensed perioperative opioids. However, CME pain policies and duration limit policies were associated with decreased days' supply and decreased MMED in the several years following implementation, respectively.ConclusionWhile we observed a slight increase in the rate of Medicare beneficiaries dispensed opioids perioperatively and a substantial decrease in MMED and days' supply for those receiving opioids, state policies examined had relatively modest effects on the main measures. Our findings suggest that these state policies may have a limited impact on opioid dispensing for a patient population that is commonly dispensed opioid analgesics to help control surgical pain, and as a result may have little direct effect on clinical outcomes for this population. Changes in opioid dispensing for this population may be the result of broader societal trends than such state policies.© 2024.
