Sepsis poses a significant public health challenge in China. However, longitudinal real-world evidence on guideline adherence and patient outcomes remains scarce. This registry aims to address these gaps by systematically capturing guideline-concordant treatment patterns and associated outcomes in ICU patients diagnosed according to Sepsis-3.0 criteria across diverse settings, thereby generating actionable evidence to improve the quality of sepsis care nationwide.

Sepsis is a major public health challenge in China and remains one of the leading causes of intensive care unit (ICU) admissions, accounting for approximately 20.6% of all ICU cases. However, longitudinal real-world data on adherence to clinical guidelines and associated patient outcomes remain limited. This multicenter observational registry is designed to systematically capture real-world management data from adult ICU patients diagnosed with sepsis according to Sepsis-3.0 criteria. The study will assess current treatment practices and document infection types, anatomical sites, pathogen profiles, and key clinical outcomes. By examining the relationship between treatment patterns and outcomes, this study aims to generate actionable evidence to improve the quality of sepsis care in China. The findings will help identify practice variability, support updates to national guidelines, and promote standardized, evidence-based management across the country.
