IL-6 and Hemogram-Derived Inflammatory Indices for Mortality Prediction in Postoperative ICU Patients

This prospective observational cohort study aims to evaluate the predictive value of interleukin-6 (IL-6) levels and hemogram-derived inflammatory scores for morbidity and in-hospital mortality in postoperative patients admitted to the intensive care unit (ICU). IL-6 levels and inflammatory indices will be assessed at ICU admission and at 24 hours using data obtained from routine clinical care. Associations between these biomarkers and clinical outcomes, including mortality, morbidity, antibiotic use, and duration of mechanical ventilation, will be evaluated after adjustment for illness severity.
