Gender-based differences in outcome in patients with sepsis

Area of Science:

• Critical Care Medicine
• Sepsis Research
• Surgical Outcomes

Background:

• Sepsis is a life-threatening condition where patient outcomes may be influenced by gender.
• Previous suggestions indicated potentially lower mortality rates in female sepsis patients.

Purpose of the Study:

• To test the hypothesis that female patients admitted to a surgical intensive care unit with documented infection have a lower mortality rate.
• To investigate the independent predictors of mortality in critically ill surgical patients with infection.

Main Methods:

• Retrospective analysis of prospectively collected data from a university hospital's surgical intensive care unit.
• Included 443 patients with documented infection (sepsis, severe sepsis, or septic shock).
• Analyzed demographic data, APACHE II and III scores, systemic inflammatory response syndrome scores, gender, age, and hospital mortality using statistical analyses including multivariate analysis of variance.

Main Results:

• Overall mortality for sepsis patients was 23.5%.
• No significant difference in mortality rates between male and female patients overall, except in octogenarians.
• Multivariate analysis identified APACHE III score, maximal multiple organ dysfunction score, and female gender as independent predictors of mortality.

Conclusions:

• Contrary to initial hypotheses, female gender is an independent predictor of increased mortality in critically ill surgical patients with documented infection.
• Severity scores (APACHE III) and organ dysfunction are key factors influencing mortality in this population.
