Use of Lactate-to-Albumin, CRP-to-Albumin, and Procalcitonin-to-Albumin Ratios to Predict Mortality in ICU Patients

Poland212 participantsStarted 2025-03-21

Plain-language summary

This observational study aims to determine whether three blood test ratios - lactate-to-albumin, CRP-to-albumin, and procalcitonin-to-albumin - can predict in-hospital mortality among critically ill adults. The study includes all adult patients admitted in 2024 to the ICU Ward B at the Silesian Center for Heart Diseases (SCCS) in Zabrze. Researchers will analyze retrospective clinical and laboratory data from electronic medical records, including lab values collected at ICU admission, patient demographics, diagnoses, and outcomes. The biomarker ratios will be manually calculated in Excel and statistically evaluated. The main goal is to assess whether these ratios are associated with patient survival and to identify predictive cut-off values to support early risk stratification in the ICU setting.
