Postoperative Opioid Pain Medication Usage Following Adult Tonsillectomy.

INTRODUCTION: The purpose of this study was to determine if short-term, high-quantity opioid use following adult tonsillectomy in active duty military members results in opioid misuse, using a proxy measure of referrals to substance abuse rehabilitation programs. MATERIALS AND METHODS: An Institutional Review Board-approved retrospective chart review was performed of 741 active duty patients who underwent tonsillectomy between 2012 and 2017. Data collection included preoperative medications within 60 days of surgery, all postoperative opioid prescriptions up to 12 months following surgery, and referrals to substance abuse rehabilitation within a year of surgery. RESULTS: Out of 741 patients, 658 met inclusion criteria. Fifty-one percent were women and the average age was 26 years. Fifty-nine percent of patients received 5 mg/325 mg oxycodone/acetaminophen as their initial postoperative pain medication. The average number of opioid tablets prescribed was 70 ± 18. Ninety three percent of patients received at least 60 tabs. The refill rate within 30 days of tonsillectomy was 38.6%. In the year following surgery, 25.4% of patients received additional doses of outpatient opioids for other indications. Nineteen patients (2.9%) were referred for substance abuse treatment within 1 year of tonsillectomy: seventeen for alcohol abuse, one for marijuana, and one for alcohol/marijuana. There were no referrals for opiate misuse or abuse. CONCLUSION: Short-term, high-quantity opioid treatment of post-tonsillectomy pain in active duty adults does not result in long-term opioid misuse, as measured by substance abuse treatment program referrals within a year after surgery. This finding supports the appropriateness of adequate short-term narcotic medication treatment. The long-term readiness of these patients appears unaffected by long-term opioid misuse or abuse. Even with this finding, there is an institutional shift to multi-modality pain management and appropriate opioid reduction to further mitigate the risk of opioid misuse. Extrapolation of these findings to all adult tonsillectomy patients should be done with caution, as there are several protective factors in the active duty population such as stable full-time employment with mandatory random drug screening.
