Abstract

Abstract : Objective: To quantify the frequency and intensity of adverse events (AEs), commonly known as side effects, experienced by children receiving either ibuprofen or oxycodone for pain management following an acute fracture. Secondary objectives were to quantify functional outcome impairment and describe demographic and clinical characteristics associated with AEs. Design: Observational cohort study. Setting: Paediatric emergency department. Patients: Patients (n=240) aged 4–16 years diagnosed with an acute fracture. Intervention: Prescribed either ibuprofen (n=179) or oxycodone (n=61) for pain. Main outcome measures: Families were called for the first 3 days after discharge to report the presence and intensity of AEs and their child's functional outcomes (ability to eat, sleep, play or attend school). Results: On day 1, children using oxycodone were more likely to report any AE (χ 2 1 =13.5, p<0.001), nausea (χ 2 1 =17.0, p<0.001), vomiting (χ 2 1 =11.2, p<0.001), drowsiness (χ 2 1 =13.7, p<0.001), constipation (χ 2 1 =8.9, p=0.003) and dizziness (χ 2 1 =19.1, p<0.001), compared with those using ibuprofen. Children receiving oxycodone reported greater severity of abdominal pain (oxycodone: mean 5.4 SD 3.1; ibuprofen mean 2.5 SD 1.4, F 1 13 =6.5, p=0.02) on day 1 and worse intensity of constipation (oxycodone: mean 4.9 SD 2.1; ibuprofen mean 3.2 SD 2.2, F 1 33 =4.5, p=0.04) over all 3 days. Use of oxycodone was associated with an increased odds of experiencing an AE on day 1 (OR=1.31 (95% CI 1.13 to 1.52)). Higher pain scores (OR=1.50 (95% CI 1.12 to 2.01)), lower extremity fracture (OR=1.25 (95% CI 1.07 to 1.47)) and undergoing ED sedation (OR=1.16 (95% CI 1.01 to 1.34)) were associated with missing school. Higher pain scores (OR=1.50 (95% CI 1.14 to 1.97)) and lower extremity fractures (OR=1.23 (95% CI 1.07 to 1.43)) were also associated with less play. Conclusions: Oxycodone is associated with more frequent AEs overall, higher intensity gastrointestinal AEs and greater functional limitations compared with ibuprofen. Lower extremity fractures cause more functional limitations than upper extremity fractures. Clinicians should consider these differences when providing fracture pain care for children.
