Insights
Despite a 2017 FDA black-box warning, perioperative tramadol use in children under 12 continues. Factors like sex, age, and comorbidities influence prescribing, necessitating interventions to reduce its use in pediatric surgery.
Area of Science:
- Pediatric Surgery
- Pharmacology
- Public Health
Background:
- The U.S. Food and Drug Administration (FDA) issued a black-box warning in 2017, contraindicating tramadol in children younger than 12 years.
- Longitudinal trends and factors influencing perioperative tramadol use in pediatric surgical patients remained unclear following the warning.
Purpose of the Study:
- To evaluate temporal trends in perioperative tramadol use in children after the FDA's 2017 black-box warning.
- To identify patient and institutional factors associated with tramadol use in pediatric surgical patients.
Main Methods:
- A retrospective, multi-institutional cohort study was conducted using the Pediatric Health Information System database.
- Data included children aged 2-18 years who underwent one of ten common surgeries between January 2009 and February 2020.
- Hierarchical multivariable logistic regression analysis was used to identify factors associated with tramadol use.
Main Results:
- Of 477,153 children, 1.2% received tramadol. Post-warning, 16.1% of tramadol recipients were under 12 years old.
- Tramadol use in children under 12 decreased from 1.87% in 2016 to 0.66% in 2019.
- Factors increasing tramadol likelihood included female sex, age ≥12 years, Midwest location, and specific comorbidities (gastrointestinal, metabolic, transplant-related). Hispanic/Latino ethnicity and public insurance were associated with decreased use.
Conclusions:
- Tramadol prescribing persists in children under 12 undergoing surgery, despite the FDA contraindication.
- Patient demographics, comorbidities, and institutional factors significantly influence perioperative tramadol use.
- Interventions are necessary to further reduce the use of tramadol in pediatric surgical patients.
Introduction:
The U.S. Food and Drug Administration (FDA) issued a black-box warning in 2017 contraindicating tramadol in children <12 y. Longitudinal trends and factors associated with perioperative tramadol use in children remain unclear.
Methods:
A retrospective, multi-institutional cohort study utilizing the Pediatric Health Information System database was performed for children 2-18 y who underwent one of ten common surgeries from 1/2009-2/2020. Temporal trends correlated with the FDA tramadol contraindication were evaluated. Hierarchical multivariable logistic regression analysis identified factors associated with tramadol use.
Results:
Of 477,153 children undergoing surgery, 5857(1.2%) received tramadol during hospitalization. Tramadol use occurred in 942 (16.1%) children after the black-box warning, 390 of whom were <12 y. For children <12 y, annual tramadol use peaked at 1.87% (2016) and decreased to 0.66% (2019). Female sex (odds ratio OR 1.32; 95% confidence interval CI:1.24,1.40), age ≥12 y (OR 2.79; 95%CI: 2.62,2.97), and Midwest location (OR 4.07; 95% CI:1.64,10.11) increased likelihood of receiving tramadol. Tramadol use was more likely after cholecystectomy (OR 1.17; 95% CI:1.04,1.32) and in children with gastrointestinal (OR 2.39; 95% CI: 2.19,2.60), metabolic (OR 1.39; 95% CI:1.26,1.53) or transplant-related (OR 1.82; 95% CI: 1.57,2.10) comorbidities. Children of Hispanic/Latino ethnicity and those with public insurance had decreased likelihood of receiving tramadol. Adjusting for patient and hospital characteristics, children <12 y were less likely to receive tramadol following the black-box warning (OR 0.65; 95% CI: 0.59,0.70).
Conclusions:
Despite the FDA contraindication, tramadol prescribing continues among children <12 y undergoing surgery, with use varying by patient and institutional factors. Interventions are required to reduce perioperative tramadol use in children.
