The Prognostic Value of Red Cell Distribution Width-to-Albumin Ratio for 28-Day Mortality in Sepsis Patients: A Multicenter Analysis Based on the eICU Collaborative Research Database
Clinical Report: Evaluating the Red Cell Distribution Width-to-Albumin Ratio as a Prognostic Indicator for 28-Day Mortality in Patients with Sepsis
Overview
This study investigates the relationship between the red blood cell distribution width-to-albumin ratio (RAR) and 28-day mortality in sepsis patients. Findings indicate that elevated RAR levels are independently associated with increased mortality risk.
Background
Sepsis is a leading cause of mortality in intensive care units globally, necessitating effective prognostic tools for risk assessment. The RAR combines insights into inflammation and nutritional status, making it a potentially valuable indicator for critically ill patients. Understanding its prognostic significance could enhance clinical decision-making in sepsis management.
Data Highlights
RAR Group
28-Day Mortality Rate
P-Value
High RAR (≥5.9)
23.0%
<0.001
Low RAR (<5.9)
9.9%
<0.001
Key Findings
The study included 13,888 adult patients with sepsis.
High RAR was associated with a 28-day mortality rate of 23.0% compared to 9.9% in the low-RAR group (P<0.001).
Each unit increase in RAR correlated with an 8% higher risk of mortality (HR 1.08, 95% CI 1.07–1.10, P<0.001).
Subgroup analyses confirmed the association across various demographics including age and sex.
A non-linear dose-response relationship was observed, indicating progressively higher mortality risk with increased RAR levels.
Clinical Implications
The RAR may serve as a practical tool for risk stratification in sepsis patients, aiding clinicians in identifying those at higher risk of mortality. Further validation in diverse clinical settings is necessary to establish its utility in routine practice.
Conclusion
Elevated RAR levels at admission are significantly linked to increased 28-day mortality in sepsis patients, suggesting its potential role as a prognostic indicator.
