Purpose: The purpose of this study is to determine the prognostic value of erythrosite distribution width (RDW) in septic patients in the intensive care unit (YBU). Tool and Method: This single-centric study includes a retrospective analysis of critical sepsis patients. Patients' demographic data, comorbidities, RDW, 3rd day (RDW3) and 7th day RDW (RDW7) values, acute physiology and chronic health assessment-II (APACHE-II) score, hemodialysis and invasive mechanical ventilation (IMV) needs were compared between the survivors and the deceased. Patients were also divided into two groups as high (> 14.5%) and normal (≤ 14.5%) RDW. Logistic regression analysis was conducted to determine the independent risk factors for mortality. Results: Hundreds of two septic patients were included in the study. The remains had a lower RDW compared to the deceased (the RDW, RDW3 and RDW7 values accepted to the YBU, p<0,05 for all). Patients in the high RDW group had a higher APACHE-II score than patients in the normal RDW group, a higher sepsic shock presence, a higher IMV need and a higher mortality rate (p<0,05 for the whole). This study found septic shock presence, RDW3 value and IMV need as independent risk factors for mortality. Result: In this study, the RDW3 value was significantly associated with mortality in critical septic patients and has a significant value in forecasting the prognosis of septic patients.
