Predictors of Early Mortality in Geriatric Patients after Hemiarthroplasty for Femoral Neck Fracture

Aim: Hemiarthroplasty is an appropriate treatment option for hip fractures that provides early mobilization, and good functional results. In the available literature, there are few studies that particulary investigate the risk factors affecting the 30- day mortality after hemiarthroplasty in geriatric patients with hip fractures. This study aimed to determine patient-related factors and biochemical predictors, which were easily accessible, inexpensive, and routinely examined in the perioperative period of 30-day mortality in geriatric patients after hemiarthroplasty for femoral neck fractures. Materials and methods: We enrolled 169 patients in our study, retrospectively. Age, body mass index, hospitalization time from admission to surgery, total hospitalization time, comorbidities, American Society of Anesthesiologists scores, blood transfusions, anticoagulant medications, albumin and plasma replacements, preoperative and postoperative hemogram, and biochemical tests were analyzed to determine the major predictors of 30-day mortality. Results: The 30-day mortality rate was 14.2%. Multivariate analysis indicated increased age (>80 years of age) (1.095 odds ratio, p = 0.029), American Society of Anesthesiologists score (3.584 odds ratio, p = 0.007), and postoperative creatinine level (2.845 odds ratio, p = 0.001) as the major predictors of 30-day mortality after hemiarthroplasty for femoral neck fractures in geriatric patients. Conclusion: Older age (>80 years of age), higher American Society of Anesthesiologists scores (ASA score 3 or 4) and increased postoperative creatinine levels were associated with an increased risk of 30-day mortality
