Motorcycle-related trauma: effects of age and site of injuries on mortality. A single-center, retrospective study [post]

2020 unpublished
Motorcyclists are often victims of road traffic incidents. Though elderly patients seem to have worse survival outcomes and sustain more severe injuries than younger patients, concordance in the literature for this does not exist. The aim of the study is to evaluate the impact of age and injury severity on the mortality of patients undergoing motorcycle trauma. Methods Data of 1725 patients consecutively admitted to our Trauma Center were selected from 2002 to 2016 and retrospectively analyzed.

Mortality rates were analyzed for the overall population and patients with Injury Severity Score (ISS) ≥ 25. Differences in survival among age groups were evaluated with Log-Rank test and multivariate logistic regression models were created to identify independent predictors of mortality. Results A lower survival rate was detected in patients older than 55 years (83,6% vs 94,7%; p = 0.049) and in those sustaining critical injuries (ISS ≥ 25, 61% vs 83% p = 0.021). Age ( p =0,027; OR: 1,03), ISS ( p <0,001; OR: 1,09), Revised Trauma Score (RTS) ( p <0,001; OR: 0,47) resulted independent predictors of death. Multivariate analysis identified head ( p <0,001; OR: 2,04), chest ( p <0,001; OR: 1,54), abdominal ( p <0,001; OR: 1,37) and pelvic ( p =0,014; OR: 1,26) injuries as independent risk factors related to mortality as well. Compared to the theoretical probability of survival, patients of all age groups showed a survival advantage when managed at a level I Trauma Center. Conclusions We detected anatomical injury distributions and mortality rates among three age groups.
