Abstract
ObjectiveThis study aimed to determine the rate and risk factors of allogeneic red blood cell transfusions (ABT) after hemiarthroplasty (HA) in elderly patients with femoral neck fracture (FNF).MethodsThe subjects of the study were elderly patients (≥65 years old) who were admitted to the geriatric trauma orthopedics ward of Beijing Jishuitan Hospital between March 2018 and June 2019 for HA treatment due to an FNF. The perioperative data were collected retrospectively, and univariate and multivariate stepwise logistic regression analyses were performed to determine the post-operative ABT rate and its risk factors.ResultsThere were 445 patients in the study, of whom 177 (39.8%) received ABT after surgery. Multivariate stepwise logistic regression analysis showed that preoperative low hemoglobin (Hb), high intraoperative blood loss (IBL), advanced age, and a low body mass index (BMI) are independent risk factors of ABT after HA in elderly FNF patients.ConclusionABT after HA is a common phenomenon in elderly patients with FNF. Their post-operative ABT needs are related to preoperative low Hb, high IBL, advanced age, and low BMI. Therefore, ABT can be reduced by taking these factors into account. When the same patient had three risk factors (preoperative low hemoglobin, advanced age, and low BMI), the risk of ABT was very high (78.3%). Also, when patients have two risk factors of preoperative low hemoglobin and low BMI, the risk of ABT was also high (80.0%).
Highlights
Millions of elderly people worldwide suffer from hip fractures each year due to minor accidents or falls (Mitchell et al, 2017), and they are a common reason for the hospitalization of the elderly
A total of 445 patients were included in the study, and the outcomes showed that preoperative low Hb, high intraoperative blood loss (IBL), advanced age, and a low body mass index (BMI) were independent risk factors of allogeneic red blood cell transfusions (ABT) after HA in elderly Femoral neck fracture (FNF) patients
Consistent with previous studies (Yan et al, 2015; Arshi et al, 2020), we found that advanced age is an independent risk factor for ABT in elderly FNF patients after HA
Summary
Millions of elderly people worldwide suffer from hip fractures each year due to minor accidents or falls (Mitchell et al, 2017), and they are a common reason for the hospitalization of the elderly. Compared with other types of fracture, the incidence of hip fracture in the elderly is high, the mortality rate is high, and patients are prone to losing their independence (Kulshrestha et al, 2019).
