Trial Outcomes & Findings for Default Dosing Settings for Opioid Prescriptions to Adolescents and Young Adults After Tonsillectomy (NCT NCT04066829)

NCT ID: NCT04066829

Last Updated: 2022-11-01

Results Overview

Participant Flow

282 participants were eligible of whom data from 237 participants was used. 198 consented; the other 39 could not be approached for consent. The IRB approved analysis of Electronic Medical Record data for these patients for the primary outcomes only, determining that review of electronic medical record data was no more than minimal risk and was justified to maximize sample size and power in light of decreased tonsillectomy volume at the University of Michigan owing to COVID-19.

45 participants who were initially eligible to participate in the study were excluded because they declined to participate, withdrew or did not undergo a tonsillectomy, did not receive a discharge opioid prescription, had prior opioid use, or opted for an opioid sparing pathway.
