Association of race and socioeconomic status with time to pain control among pediatric trauma patients managed nonoperatively.

BACKGROUND: Few studies have evaluated racial/ethnic inequities in acute pain control among hospitalized injured children. We hypothesized that there would be inequities in time to pain control based on race/ethnicity and socioeconomic status. METHODS: We performed a retrospective cohort study of all injured children (7-18 years) admitted to our level 1 trauma center between 2010 and 2019 with initial recorded numerical rating scale (NRS) scores of >3 who were managed nonoperatively. A Cox regression survival analysis was used to evaluate the time to pain control, defined as achieving an NRS score of ≤3. RESULTS: Our cohort included 1,787 admissions. The median age was 14 years (interquartile range, 10-18), 59.5% were male, 76.6% identified as White, 19.9% as Black, and 2.4% as Hispanic. The median initial NRS score was 7 (interquartile range, 5-9), and the median time to pain control was 4.9 hours (95% confidence interval, 4.6-5.3). Insurance status, as a marker of socioeconomic status, was not associated with time to pain control ( p = 0.29). However, the interaction of race/ethnicity and deprivation index was significant ( p = 0.002). Specifically, the socioeconomic deprivation of a child's home neighborhood was an important predictor for non-White children ( p <0.003) but not for White children ( p = 0.41) and non-White children from higher deprivation neighborhoods experienced greater times to pain control (hazard ratio, 1.55; 95% confidence interval, 1.16-2.07). Being female, older, presenting with higher initial NRS scores, and having history of attention-deficit/hyperactivity disorder were all associated with longer times to pain control. Other injury characteristics and psychiatric history were evaluated but ultimately excluded, as they were not significant. CONCLUSION: Greater neighborhood socioeconomic deprivation was associated with prolonged time to pain control for non-White children admitted after injury and managed nonoperatively. Further work is needed to understand inequities in pain control for injured patients. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level IV.
