Factors associated with opioid use after endoscopic sinus surgery.

Objectives/hypothesis: Responsible prescribing of postoperative pain medications is necessary in combatting the current opioid epidemic in the United States. The goal of this study was to determine which clinical factors affect opioid usage following functional endoscopic sinus surgery (FESS).

Study Design: Retrospective medical records study.

Methods: This is a single-institution retrospective study of subjects undergoing FESS by the senior author between September 2016 and December 2017. Opioid usage was assessed for each patient at the first postoperative visit. Univariate and multivariable analyses were performed to investigate factors associated with pain medication usage. Patients using opioids prior to surgery were excluded.

Results: A total of 136 patients were stratified into three groups based on number of opioid tablets taken during the first week after surgery: 31 patients (23%) took no opioids, 61 patients (45%) took one to five tablets, and 44 patients (32%) took more than five tablets. Gender, extent of surgery, revision surgery, polyp status, and cystic fibrosis did not significantly vary between the three groups. Multinomial logistic regression analysis with backward stepwise variable selection method revealed that those who had septoplasty (odds ratio [OR]: 4.84, 95% confidence interval [CI]: 1.68-13.98; P < .01) or were of younger age (OR 0.96, 95% CI: 0.93-0.99; P = .01) had significantly higher odds of taking >5 tablets.

Conclusions: The majority of patients undergoing FESS did not take more than 5 opioid tablets after surgery. Concurrent septoplasty and younger age were associated with increased opioid usage. Knowledge of such factors can help surgeons to assess opioid prescribing patterns and to counsel their patients on postoperative pain. Laryngoscope, 129:1751-1755, 2019.
