Association of Opioid Quantity and Caregiver Education with Pain Control after Pediatric Tonsillectomy.

Objective To examine whether a service guideline reducing postoperative opioid prescription quantities and caregiver-reported education to use nonopioid analgesics first are associated with caregiver-reported pain control after pediatric tonsillectomy. Study Design Prospective cohort study (July 2018-April 2019). Setting Pediatric otolaryngology service at a tertiary academic children's hospital. Subjects and Methods Caregivers of patients aged 1 to 11 years undergoing tonsillectomy (N = 764) were surveyed 7 to 21 days after surgery regarding pain control, education to use nonopioid analgesics first, and opioid use. Respondents who were not prescribed opioids or had missing data were excluded. Logistic regression modeled caregiver-reported pain control as a function of service guideline implementation (December 2018) recommending 20 rather than 30 doses for postoperative opioid prescriptions and caregiver-reported analgesic education, adjusting for patient demographics. Results Among 430 respondents (56% response), 387 patients were included. The sample was 43% female with a mean age of 5.0 years (SD, 2.5). Pain control was reported as good (226 respondents, 58%) or adequate/poor (161 respondents, 42%). Mean opioid prescription quantity was 27 doses (SD, 7.9) before and 21 doses (SD, 6.1) after guideline implementation (P < .001). Education to use nonopioids first was reported by 308 respondents (80%). In regression, prescribing guideline implementation was not associated with pain control (adjusted odds ratio, 1.3; 95% CI, 0.9-2.0; P = .22), but caregiver-reported education to use nonopioids first was associated with a higher odds of good pain control (adjusted odds ratio, 1.9; 95% CI, 1.1-3.2; P = .02). Conclusion Caregiver education to use nonopioid analgesics first may be a modifiable health care practice to improve pain control as postoperative opioid prescription quantities are reduced.
