PurposeSince 2014, a trauma system (TS) for the Provence-Alpes-Cote-d'Azur (PACA) region has been set up with protocols based on the European guidelines for the management of bleeding trauma patients. The present study aims to assess compliance with protocols in penetrating thoracic trauma on admission to a level I trauma centre and to determine whether compliance impacts morbidity and mortality.MethodsThis multicentric pre-post study included all penetrating thoracic trauma patients referred to Marseille area level I centres between January 2009 and December 2019. On the basis of the European guidelines, eight objectively measurable recommendations concerning the in-hospital trauma care for the first 24 h were analysed. Per-patient and per-criterion compliance rates and their impact on morbidity and mortality were evaluated before and after TS implementation.ResultsA total of 426 patients were included. No differences between the two groups (before and after 2014) were reported for demographics or injury severity. The median (interquartile range) per-patient compliance rate increased from 67% [0.50; 0.75] to 75% [0.67; 1.0] (p < 0.01) after implementation of a TS. The 30-day morbidity-mortality was, respectively, of 17% (30/173) and 13% (32/253) (p = 0.18) before and after TS implementation. A low per-patient compliance rate was associated with an increase in the 30-day morbidity-mortality rate (p < 0.01). Severity score-adjusted per-patient compliance rates were associated with decreased 30-day morbidity-mortality (odds ratio [IC 95%] = 0.98 [0.97; 0.99] p = 0.01).ConclusionImplementation of a TS was associated with better compliance to European recommendations and better outcomes for severe trauma patients. These findings should encourage strict adherence to European trauma protocols to ensure the best patient outcomes.© 2022. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany.
