This retrospective cohort study investigated the utility of the MELD-XI (Model for End-Stage Liver Disease-Excluding INR) score as a predictor of 30-day mortality in over 16,600 adult ICU patients with sepsis, using data from the eICU Collaborative Research Database. Patients were categorized into low, medium, and high MELD-XI score tertiles.

Significant differences were observed across these groups, with the high MELD-XI group exhibiting a greater disease burden, including higher APACHE IV and SOFA scores, lower Glasgow Coma Scale (GCS) scores, and notably elevated levels of total bilirubin, serum creatinine, and lactate.

This demonstrates that the MELD-XI, originally designed for liver disease prognosis, effectively stratifies the severity of systemic organ dysfunction in the broader sepsis population.

The study established a strong, nonlinear association between the MELD-XI score and the risk of 30-day mortality.

Crucially, a threshold effect was identified: when the MELD-XI score exceeds 25.74, the risk of death in sepsis patients rises significantly.

This suggests that the MELD-XI score can serve as a simple and practical tool for early risk assessment in the clinical setting, helping intensivists quickly identify sepsis patients at a dramatically increased risk of death.

While this finding is powerful, the authors recommend further prospective studies to validate this specific threshold and confirm the score’s utility in guiding critical treatment decisions.
