Association between platelet-albumin-bilirubin score and 30-day in-hospital mortality in patients with sepsis: evidence from a large database and machine learning modeling

The three components of the platelet-albumin-bilirubin (PALBI) score are closely related to inflammatory responses, hepatic dysfunction, and coagulation abnormalities in sepsis, but its prognostic significance in this population remains unclear. This study aimed to examine the association between PALBI score and 30-day in-hospital mortality in patients with sepsis. Data from the Medical Information Mart for Intensive Care (MIMIC-IV) database were retrospectively analyzed. Patients diagnosed with
