Nationwide Assessment of Factors Associated with Nonoperative Management of Pediatric Splenic Injury

To evaluate variation in care nationwide for children with splenic injuries at pediatric trauma, adult trauma, and nontrauma centers. We used the National Inpatient Sample from 2001 to 2010 to identify pediatric patients with splenic injury. We analyzed demographic, clinical, and hospital status characteristics. The primary objective was comparison of splenectomy rates at pediatric, adult, and nontrauma centers. We identified 34,599 patients with splenic injury. Throughout the study, 3,979 (11.5%) patients underwent splenectomy: 8.2 per cent of patients at pediatric trauma, 17.6 per cent at adult trauma, and 14.5 per cent at nontrauma centers. Multivariate regression analysis demonstrated patients had decreased odds of splenectomy at pediatric trauma centers compared with adult and nontrauma centers (OR = 0.42, P < 0.001). In addition, children aged 14 to 17 years (OR = 2.5) with injury severity score > 14 (OR = 5.8) had increased odds of undergoing splenectomy. In this nationwide sample, children with splenic injury treated at adult trauma and nontrauma centers had significantly higher rates of splenectomy compared with children treated at pediatric trauma centers. We highlight the need for interventions that ensure all injured children receive appropriate and high quality trauma care.
