Sex-Based Differences in Polytraumatized Patients between 1995 and 2020: Experiences from a Level I Trauma Center.

: The aim of this study was to examine sex-related differences in the outcomes of polytraumatized patients admitted to a level I trauma center. : This was a retrospective data analysis of 980 consecutive polytraumatized patients admitted to a single level I trauma center between January 1995 and December 2020. : Among all patients, about 30% were female, with a significantly higher age and significantly higher rates of suicidal attempts. No sex-related differences regarding injury severity or trauma mechanisms could be seen, but female patients had significantly higher overall in-hospital mortality rates compared to male patients. Even in the elderly group of patients, elderly female patients were significantly older compared to elderly male patients, with significantly increased lengths of hospital stay. In the elderly group of patients, no sex-related differences regarding injury severity, trauma mechanisms or mortality could be detected. Multivariate analysis revealed suicidal attempt, severe head injury and age > 54 years as independent prognostic factors in the survival of polytraumatized patients. : Distinctive sex-related differences can be found, with female polytraumatized patients being significantly older and having higher overall mortality rates with significantly increased LOS. Our study suggests a strong sex-independent influence of age, suicidal attempt and severe head injury on the outcomes of polytraumatized patients.
