Clinical Report: Predictive Value of Hematologic and Metabolic Markers for 28-Day Mortality in Patients with Sepsis
Overview
This study evaluates the predictive value of hematologic and metabolic indices for 28-day mortality in sepsis patients. Key findings indicate that the uric acid-to-albumin ratio (UA/Alb) is the most predictive marker, outperforming other indices.
Background
Sepsis is a critical condition that leads to high mortality rates, particularly in intensive care settings. Early identification of patients at risk is crucial for improving outcomes. The study investigates simple laboratory-derived indices that could serve as prognostic biomarkers for mortality prediction in sepsis.

Key Findings
Non-survivors exhibited higher disease severity scores and distinct biochemical profiles.
All evaluated indices were significantly associated with mortality.
The UA/Alb ratio had the highest predictive performance (AUC: 0.968).
In multivariable analysis, UA/Alb ratio and SAPS II score were independent predictors of mortality.
Lower hemoglobin and albumin levels were observed in non-survivors.
Clinical Implications
Clinicians should consider the UA/Alb ratio as a valuable prognostic tool for assessing mortality risk in septic patients. Incorporating these indices into routine assessments may enhance early risk stratification and guide therapeutic interventions.
Conclusion
Hematological and metabolic indices can significantly improve early mortality prediction in sepsis. The UA/Alb ratio stands out as a particularly effective marker, warranting further validation in clinical practice.
