Objective: In this study, we aimed to investigate the clinical features of geriatric hip fracture cases that underwent hemiarthroplasty surgery and to reveal the predictors of hospitalization in ICU accordingly. Methods: In this study, 158 geriatric patients who underwent hemiarthroplasty surgery for femoral neck fracture between January 2017 and December 2019 were retrospectively analyzed. The patients were divided into two groups as patients who were admitted to the ICU (ICU) and patients who were not admitted to the ICU (non-ICU). The clinical characteristics of the patients were compared between the two groups, and predictors of ICU admission were determined by a multivariate regression model. Results: The mean age of the patients was 82.16±7.5 years, the mean duration of ICU hospitalization was 1.98±1.4 days, and the mortality rate was 9.5%. One hundred nineteen of the patients (75.31%) were admitted to the ICU after the surgery.According to the results of the univariate regression analysis, advanced age, presence of comorbidities (coronary artery disease, cerebrovascular disease), number of comorbidities, ASA score, Charlson age-corrected comorbidity index, transfusion of erythrocyte suspension, and cement application were significant risk factors for admission to ICU (p<0.02 for each). According to multivariate regression analysis, ASA score (OR=2.77, p=0.04) and cement application (OR=5.97, p<0.001) were determined as independent risk factors for hospitalization in ICU. Conclusion: Factors that are predictors of the need for ICU after hemiarthroplasty surgery (ASA score and cement application) should be considered in geriatric patients. More comprehensive research is required to show the potential effects of these predictors better.
