Comparison of mortality rates and risk factors for mortality between proximal femoral nailing and bipolar hemiarthroplasty for hip fractures

Abstract

Aims: The study aimed to compare in-hospital and post-discharge mortality rates and identify risk factors for patients who underwent bipolar hemiarthroplasty (BHA) or proximal femoral nailing (PFN) for hip fractures. Methods: The files of 395 patients, consisting of 129 BHA and 266 PFN patients performed between January 2017 and October 2022, were analyzed retrospectively. The demographic characteristics of the patients, in-hospital and 1-year post-discharge mortality rates, and risk factors that may have affected these mortality rates were analyzed. Results: There was no significant difference between the two groups in terms of demographic characteristics, intensive care unit (ICU) stay, American Society of Anesthesiologists (ASA) score, time to surgery, and intubation (p>0.05). The length of hospital stay and blood transfusion rates were higher in the BHA group (p0.05). The 1-year post-discharge mortality rates were higher for patients with a higher mean age, longer length of hospital stay, longer length of ICU stay, time to surgery (>48 h), for patients who underwent intubation and blood transfusion, and for those with an ASA score of 4 (p
