| Abstract |
Importance: In response to the opioid epidemic, recommendations from some pain societies have encouraged surgeons to embrace multimodal pain regimens with the intent of reducing opioid use in the postoperative period, including by prescribing gabapentinoids.
Objective: To describe trends in postoperative prescribing of both gabapentinoids and opioids after a variety of surgical procedures by examining nationally representative Medicare data and further understand variation by procedure.
Design, setting, and participants: This serial cross-sectional study of gabapentinoid prescribing from January 1, 2013, through December 31, 2018, used a 20% US Medicare sample. Gabapentinoid-naive patients 66 years or older undergoing 1 of 14 common noncataract surgical procedures performed in older adults were included. Data were analyzed from April 2022 to April 2023.
Exposure: One of 14 common surgical procedures in older adults.
Main outcomes and measures: Rate of postoperative prescribing of gabapentinoids and opioids, defined as a prescription filled between 7 days before the procedure and 7 days after discharge from surgery. Additionally, concomitant prescribing of gabapentinoids and opioids in the postoperative period was assessed.
Results: The total study cohort included 494 922 patients with a mean (SD) age of 73.7 (5.9) years, 53.9% of whom were women and 86.0% of whom were White. A total of 18 095 patients (3.7%) received a new gabapentinoid prescription in the postoperative period. Of those receiving a new gabapentinoid prescription, 10 956 (60.5%) were women and 15 529 (85.8%) were White. After adjusting for age, sex, race and ethnicity, and procedure type in each year, the rate of new postoperative gabapentinoid prescribing increased from 2.3% (95% CI, 2.2%-2.4%) in 2014 to 5.2% (95% CI, 5.0%-5.4%) in 2018 (P < .001). While there was variation between procedure types, almost all procedures saw an increase in both gabapentinoid and opioid prescribing. In this same period, opioid prescribing increased from 56% (95% CI, 55%-56%) to 59% (95% CI, 58%-60%) (P < .001). Concomitant prescribing also increased from 1.6% (95% CI, 1.5%-1.7%) in 2014 to 4.1% (95% CI, 4.0%-4.3%) in 2018 (P < .001).
Conclusions and relevance: The findings of this cross-sectional study of Medicare beneficiaries suggest that new postoperative gabapentinoid prescribing increased without a subsequent downward trend in the proportion of patients receiving postoperative opioids and a near tripling of concurrent prescribing. Closer attention needs to be paid to postoperative prescribing for older adults, especially when using multiple types of medications, which can have adverse drug events.
