AbstractWe reviewed all trauma deaths occurring in the urban area of Milan during one year. Autopsy reports were cross-referenced with pre- and in-hospital records and the Injury Severity Score was calculated by a senior surgeon. Causes of deaths were defined as central nervous system injury (CNS), hemorrhage (HEM), combined central nervous system injury and hemorrhage (CNS + HEM), and burns (BURN). Places of death were considered the scene (DOS), during transportation (DOA), the emergency room (DER), and hospital. Two multidisciplinary commissions reviewed patient reports and deaths were judged non-preventable, possibly preventable or frankly preventable, using the unanimous decision rule. The TRISS method was used to calculate the probability of survival for in-hospital deaths. Overall trauma deaths were 255 with 78.04% blunt and 16.08% penetrating traumas. Burns accounted for 5.88%. CNS and CNS + HEM caused 171 (67.05%) deaths. DOS were 91, DOA 48, DER 34, and in-hospital deaths 33. Victims found dead (49 individuals) were excluded from further analysis. The commissions classified 56.31% of deaths as non-preventable, 32.03% as possibly preventable and 11.65% as frankly preventable. The Injury Severity Score decreased from DOS to in-hospital deaths (p < 0.05). The preventability rate was higher for in-hospital deaths (p < 0.05). The results of this study suggest that the development of a tiered trauma system in Milan is mandatory.
