Abstract
BackgroundPatients of motor vehicle crashes (MVCs) suffering burns are challenging for the rescue team and the admitting hospital. These patients often face worse outcomes than crash patients with trauma only. Our analysis of the German In-depth Accident Study (GIDAS) database researches the detailed crash mechanisms to identify potential prevention measures. MethodsWe analyzed the 2011 GIDAS database comprising 14,072 MVC patients and compared individuals with (Burns) and without (NoBurns) burns. Only complete data sets were included. Patients with burns obviously resulting of air bag deployment only were not included in the Burns group. Data acquisition by an on call team of medical and technical researchers starts at the crash scene immediately after the crash and comprises technical data as well as medical information until discharge from the hospital. Statistical analysis was done by Mann–Whitney-U-test. Level of significance was p<0.05. Results14,072 MVC patients with complete data sets were included in the analysis. 99 individuals suffered burns (0.7%; group “Burns”). Demographic data and injury severity showed no statistical significant difference between the two groups of Burns and NoBurns. Injury severity was measured using the Injury Severity Score (ISS). Direct frontal impact (Burns: 48.5% vs. NoBurns: 33%; p<0.05) and high-energy impacts as represented by delta-v (m/s) (Burns: 33.5±21.4 vs. NoBurns: 25.2±15.9; p<0.05) were significantly different between groups as was mortality (Burns: 12.5% vs. NoBurns: 2.1%; p<0.05). Type of patients’ motor vehicles and type of crash opponent showed no differences. ConclusionsOur results show, that frontal and high-energy impacts are associated with a frequency of burns. This may serve automobile construction companies to improve the burn safety to prevent flames spreading from the motor compartment to the passenger compartment. Communities may impose speed limits in local crash hot spots.
