SOFA-2 represents meaningful progress toward a more inclusive and equitable global sepsis assessment framework

Area of Science:

• Critical Care Medicine
• Clinical Epidemiology

Background:

• The Sequential Organ Failure Assessment (SOFA) score is widely used for assessing organ dysfunction in critically ill patients.
• Existing SOFA score versions face challenges in clarity, reproducibility, and global applicability, particularly in diverse healthcare settings.

Purpose of the Study:

• To evaluate the improvements and limitations of the updated Sequential Organ Failure Assessment (SOFA-2) score.
• To assess the SOFA-2 score's calibration and clinical actionability across different global settings.

Main Methods:

• Analysis of the SOFA-2 score's updated features, including explicit scoring rules.
• Inclusion of data from low- and middle-income countries (LMICs) in the SOFA-2 development process.

Main Results:

• SOFA-2 demonstrates enhanced clarity, reproducibility, and global representation compared to previous versions.
• Initial data incorporation from LMICs begins to address applicability concerns, but significant representation imbalances persist.

Conclusions:

• SOFA-2 represents a meaningful advancement in sepsis assessment tools.
• Future sepsis frameworks require integration of context-specific evidence, consideration of structural health system constraints, and equitable participation in model development for global validity.
