Sepsis Patient Mortality Analysis Based on Red Cell Distribution Width-to-Albumin Ratio

A retrospective, multicentre cohort study extracted 13,888 adult patients meeting sepsis criteria from the eICU Collaborative Research Database. The research explores the association between the red cell distribution width-to-albumin ratio (RAR) and 28-day all-cause mortality in sepsis patients. The dataset was authored by Mao Ye and last updated on 2026-05-28.

Use Cases

• Predicting 28-day ICU mortality based on the red cell distribution width-to-albumin ratio.
• Analyzing the non-linear dose-response relationship between a biomarker ratio and patient outcomes.
• Validating a low-cost prognostic indicator for sepsis in critical care settings.
• Conducting subgroup analyses across age, sex, and comorbidity stratifications for mortality risk.

Strengths

• Includes data from 13,888 adult sepsis patients.
• Analysis is based on a multicenter cohort from the eICU Collaborative Research Database.
• Results show a statistically significant association (HR 1.50, 95% CI 1.36–1.64) between high RAR and increased mortality.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small (42.2 KB), suggesting it contains summary or processed results rather than raw patient records.
