Objectives: Red cell distribution width (RDW) is an index of red blood cell heterogeneity. A high RDW value has been independently associated with increased mortality; however the relationship has been studied very little in the orthopedic literature. The aim of this study was to evaluate the association between RDW and mortality in elderly hip fracture patients. Methods: First-time hip fracture patients older than 65 years of age were included in this study. Patients with multiple fractures or pathological fractures were excluded. Mortality data were collected via phone call at 3-month and 1-year time points from the fracture surgery. Patients who lived more than 1 year were classified as a control group (Group 1). Group 2 comprised patients who died within 1 year after fracture surgery, and Group 3 consisted of patients who died within a 3-month period after the operation. The primary variable of this study was admission RDW value. Age, gender, fracture type (extracapsular or intracapsular), American Society of Anesthesiologist score, and the Charlson Comorbidity Index were considered secondary preoperative variables. The case groups were statistically compared with the control group in terms of these variables. Results: The primary result of our study was that patients who died within 3 months and within 1 year after hip fracture surgery had a higher admission RDW value than the survivors. Conclusion: An elevated admission RDW level was associated with excess mortality in elderly hip fracture patients within postoperative 3 months and 1 year.
