Abstract

Objective: We aimed to compare adolescent mortality rates between different types of major trauma centre (MTC or level 1; adult, children's and mixed). Methods: Data were obtained from TARN (Trauma Audit Research Network) from English sites over a 6-year period (2012-2018), with adolescence defined as 10-24.99 years. Results are presented using descriptive statistics. Patient characteristics were compared using the Kruskal-Wallis test with Dunn's post-hoc analysis for pairwise comparison and χ2 test for categorical variables. Results: 21 033 cases met inclusion criteria. Trauma-related 30-day crude mortality rates by MTC type were 2.5% (children's), 4.4% (mixed) and 4.9% (adult). Logistic regression accounting for injury severity, mechanism of injury, physiological parameters and 'hospital ID', resulted in adjusted odds of mortality of 2.41 (95% CI 1.31 to 4.43; p=0.005) and 1.85 (95% CI 1.03 to 3.35; p=0.041) in adult and mixed MTCs, respectively when compared with children's MTCs. In three subgroup analyses the same trend was noted. In adolescents aged 14-17.99 years old, those managed in a children's MTC had the lowest mortality rate at 2.5%, compared with 4.9% in adult MTCs and 4.4% in mixed MTCs (no statistical difference between children's and mixed). In cases of major trauma (Injury Severity Score >15) the adjusted odds of mortality were also greater in the mixed and adult MTC groups when compared with the children's MTC. Median length of stay (LoS) and intensive care unit LoS were comparable for all MTC types. Patients managed in children's MTCs were less likely to have a CT scan (46.2% vs 62.8% mixed vs 64% adult). Conclusions: Children's MTC have lower crude and adjusted 30-day mortality rates for adolescent trauma. Further research is required in this field to identify the factors that may have influenced these findings.
