Examining Age and Postoperative Opioid Use in the Urogynecology Population: A Prospective Study

Importance: Surgeons must individualize postoperative pain management while also reducing the amount of unused prescribed opioids.

Objectives: This study compared postoperative opioid use in younger versus older women following urogynecologic surgery. We also assessed the likelihood of women returning unused opioids for safe disposal.

Study design: This was a prospective study of women undergoing pelvic reconstructive surgery divided into 2 cohorts: younger (<65 years) and older (≥65 years). Our primary outcome was total opioid use, measured in morphine milligram equivalents (MME). We also assessed the average pain score during the first week after surgery measured by a numerical pain scale (range, 0-10). Our secondary outcome was the rate of return of unused prescribed opioids at the 6-week postoperative visit utilizing a disposable drug deactivation system.

Results: From April 2019 to September 2021, 152 participants were enrolled: 92 (61%) in the younger cohort (mean age, 51 ± 8 years) and 60 (39%) in the older cohort (mean age, 72 ± 6 years). For our primary outcome, younger women used significantly more opioids during the first postoperative week compared with older women (49 ± 71 vs 28 ± 40 MME, respectively, P = 0.04), despite no difference in average pain scores (4 ± 2 younger vs 3 ± 2 older, P = 0.05). For our secondary outcome, 23% of participants returned their opioids for disposal with the drug deactivation system.

Conclusions: Younger women had higher postoperative opioid use despite similar pain scores after urogynecologic surgery. Among those prescribed opioids, a quarter of participants returned their opioids for disposal at their postoperative visit.
