Frequency of splenectomy for pediatric splenic injury in Brazil: a retrospective analysisResearch in context

Summary: Background: Non-operative management for pediatric blunt splenic injury is well established in high-income countries, leading to a low splenectomy rate in hemodynamically stable children. Splenectomy rate became a quality indicator for Trauma Center verification utilized by the American College of Surgeons Committee on Trauma. However, data on splenectomy rate in children from countries with different income levels, such as Brazil, remain limited. This study aimed to assess the post-traumatic splenectomy rate among Brazilian children over the past decade and the relation with local resources. Methods: Data on pediatric splenic injuries and splenectomies from 2008 to 2019, including patient age and admitting service (adult or pediatric), were obtained from FioCruz database, a public, free, cloud-based platform that offers extensive national health data. The regional numbers of pediatric surgeons, pediatric intensive care unit (PICU) beds, and computed tomography scanners were obtained from Brazilian national databases. A national analysis of splenectomy rate by year and service of admission and an analysis of splenectomy rate by the level of regional resources, the number of pediatric surgeons, PICU beds, and computed tomography scanners was performed. Findings: 4061 children were hospitalized with a splenic injury, and 2287 (51.8%) of them underwent splenectomy, unchanged over time. 76.8% were male and 23.1% female patients with splenic injury. Mean age was 11.61 years old. The odds of splenectomy was 14.77 times higher for pediatric patients admitted under adult surgical service compared to pediatric service (OR = 14.77, 95% CI 11.75–18.56, p
