Sex-related mortality differences in septic shock: A propensity score-matched study

Area of Science:

• Critical Care Medicine
• Epidemiology
• Sex-Specific Medicine

Background:

• Septic shock is a life-threatening condition with significant mortality.
• Understanding sex-specific differences in septic shock outcomes is crucial for targeted treatment strategies.

Purpose of the Study:

• To evaluate sex-specific differences in 28-day mortality among young adults (18-55 years) with septic shock.
• To utilize a large propensity score-matched cohort for robust analysis.

Main Methods:

• Retrospective analysis of the TriNetX network data from January 2011 to January 2020.
• Propensity score matching (1:1) of women to men with septic shock.
• Primary outcome: 28-day all-cause mortality; secondary outcomes: 90- and 180-day mortality.

Main Results:

• Analysis included 86,748 propensity score-matched patients (43,374 males, 43,374 females).
• Young women exhibited a lower 28-day mortality rate (15.3%) compared to young men (16.6%).
• This survival benefit for women was consistent across 90-day and 180-day mortality.

Conclusions:

• Young women with septic shock demonstrate significantly lower mortality than young men.
• These findings suggest important sex-related differences in septic shock pathophysiology or response to treatment.
• Further research is warranted to explore the therapeutic implications of these sex-specific differences.
