Abstract

Objective: Large sample investigations for risk factors for pneumonia in elderly patients after hip fracture surgeries are lacking. The purpose of this study is to determine the incidence and risk factors for postoperative pneumonia in geriatric patients following hip fracture operations.

Methods: A retrospective study of incidence and risk factors in a tertiary referral center between 2016 and 2020 was conducted. Geriatric patients who developed postoperative pneumonia after surgeries of hip fracture during hospitalization stay were defined as cases and those without as controls. Multivariate logistic regression model was used to evaluate risk factors for postoperative pneumonia.

Results: This study included 3147 patients, and 182 developed postoperative pneumonia, denoting the rate of 5.8%. In the multivariate analyses, age (OR 1.04; 95% CI 1.02-1.06), sex (males) (OR 2.27; 95% CI 1.64-3.13), respiratory disease (OR 3.74; 95% CI 2.32-6.04), heart disease (OR 1.68; 95% CI 1.14-2.47), cerebrovascular disease (OR 1.58; 95% CI 1.11-2.27), liver disease (OR 2.61; 95% CI 1.33-5.15), preoperative stay (OR 1.08; 95% CI 1.05-1.11) and general anesthesia (OR 1.61; 95% CI 1.15-2.27) were identified as independent risk factors for postoperative pneumonia.

Conclusions: This study identified several risk factors for pneumonia in geriatric patients after hip fracture operations, providing a viable preventive strategy for optimizing clinical conditions for reduction of postoperative pneumonia.
