INVESTIGATION OF THE RELATIONSHIP BETWEEN MORTALITY AND RED CELL DISTRIBUTION WIDTH, MEAN PLATELET VOLUME, PLATELET-TO-LYMPHOCYTE RATIO, AND NEUTROPHIL-TO-LYMPHOCYTE RATIO IN GERIATRIC PATIENTS

Introduction: This study aimed to investigate the relationship between all-cause mortality and the values of red-cell distribution width, mean platelet volume, platelet-to-lymphocyte ratio, and neutrophil-to-lymphocyte ratio in geriatric patients who had become bedridden. Materials and Method: The retrospective study reviewed 1981 patients aged 65-104 years who were bedridden and followed at University of Health Sciences, Antalya Training and Research Hospital Family Medicine Clinic from 2016 to 2018. Due to the effects on studied test parameters, patients with anemia were excluded from the study, and 898 patients included.The baseline variables red cell distribution width, mean platelet volume, platelet-to-lymphocyte ratio, and neutrophil-tolymphocyte ratio were compared between survivors and non-survivors. Results: Of the 898 patients, 141 (15.7%) died during follow-up. Mean red cell distribution width (15.7%), platelet-to-lymphocyte ratio (140.5), and neutrophilto-lymphocyte ratio (3.14) levels in non-survivors were statistically significantly higher than those of survivors (14.9%, p
