ABSTRACT Background/Aims: Pneumonia is one of the most important causes of mortality and morbidity worldwide. There is a need for simpler and easier markers that we can use to determine the prognosis of pneumonia patients in emergency departments. In this study, we aimed to evaluate the relationship between RDW/Albumin and BUN/Creatinine ratio and 30-day mortality, length of hospital stay and need for intubation in patients admitted to the emergency department and hospitalized in intensive care unit with a diagnosis of pneumonia. Methods: The study included 98 patients admitted to the emergency department between January 2022 and December 2023 and hospitalized in the intensive care unit due to pneumonia. Patients were divided into two groups as discharged and exited patients. The relationship between RDW/Albumin and BUN/Creatinine ratios and mortality was compared between the groups. Results: According to the findings of the study, RDW/Albumin ratio was found to significantly predict mortality in patients hospitalized from the emergency department to the intensive care unit. Another finding was that the BUN/Creatinine ratio also significantly predicted mortality (p
