Postoperative Opioid Prescribing and Consumption Patterns after Tonsillectomy.

Abstract

Despite increased concern with the opioid epidemic, literature remains scant regarding narcotic prescription and use following tonsillectomy. Retrospective cohort study with telephone interview. A chart review from January to August 2018 evaluated the difference between prescribed amounts of narcotic and patient-reported usage following tonsillectomy (Current Procedural Terminology codes 42821 and 42826). Patients were excluded if they used opioids for chronic pain, had a history of chronic opioid use or substance abuse, or underwent tonsillectomy to exclude malignancy. A telephone interview assessed opioid and nonopioid usage and pain control postoperatively, including amount and form of narcotics remaining. Sixty-four patients were enrolled at a mean 4.47 months after tonsillectomy. The mean ± SD prescribed morphine milligram equivalent (MME) was 456.1 ± 281.7, with only 302.8 ± 206.2 consumed. The mean MME prescribed per day was 74.1 ± 44.8, and average days of narcotic usage postoperatively was 9.6 ± 4.6, correlating with a mean MME per day of 49.2 ± 34.3 if the maximum prescribed dose per day was consumed. Fifty-four (84.4%) patients reported pain as well controlled. Forty-three (67.2%) patients reported residual narcotic medication, with 228.1 ± 208.5 MMEs remaining per patient. Narcotic solutions were more completely consumed than tablet forms, with 23.1% and 44.0% remaining, respectively. Patients cited uncertainty about safe disposal and safeguarding for future use as reasons for keeping residual narcotic. Patient-reported narcotic use is significantly lower than the amount prescribed after tonsillectomy for benign disease. Providers can use these data to adjust narcotic-prescribing patterns while maintaining appropriate pain management for patients undergoing tonsillectomy.
