Impact of gender on post- traumatic intensive care and outcomes

Abstract

Abstract Background Several reports indicate gender disparities in health care provision. There is a well-documented male patient dominance in intensive care unit (ICU) admittance. It is not established if this difference reflects medical needs or is influenced by other factors. The aim of the current study was to investigate if patient gender influences the pattern of ICU admittance in a cohort of trauma patients. Methods Data from patients admitted to an urban trauma centre over a 10-year interval were linked to regional and national health registries to obtain data on demographics, co-comorbidities, trauma-related variables, ICU-admittance patterns and mortality. The association between gender and ICU-admission were explored using logistic regression analysis. The association between gender and short- and long-term mortality were explored using Cox regression models. Results In this study cohort of approximately 14,000 trauma patients, men had a higher probability of being admitted to the ICU after initial trauma resuscitation. The difference was limited to patients with less severe injuries (ISS < 15). No differences were noted in short-term survival, whereas men had a higher long-term mortality. Conclusions In this retrospective cohort study we found a difference between men and women in post trauma ICU admittance patterns, restricted to less injured patients, where men had a higher probability of ICU admittance. Whether this is a true gender bias or an effect of other factors not analysed in this study remains unknown. This finding warrants further studies.
