Abstract

Objective: To study the relationship between red blood cell distribution width (RDW) and short-term mortality of hip fracture in middle-aged and older adults.

Methods: A retrospective cohort of electronic medical records at a single hospital over a 2-year period between 2020 and 2021. We received the records of 233 patients aged > 50 years who suffered from hip fracture. the clinical data including patients demographics, comorbidities at the time of admission, type of surgery, blood examination, 3-months mortality, 6-months mortality and 1-year mortality. the relationship between RDW and short-term mortality of hip fracture were analyzed. the cohort was then divided into two groups based on their RDW levels at the time of admission: low (RDW < 13.6%) and high (RDW ≥ 13.6%).

Results: Results the mean age was 78.03 ± 12.09 years; 64.81% were woman. At admission, 80 patients (34.33%) had high RDW levels and 153 patients (65.67%) had low RDW levels. there were no statistically significant differences between the groups with regard to sex, type of operation, duration of surgery and hospitalization length. Patients with high RDW had more comorbidities when compared to patients with low RDW levels (p < 0.05). All-cause mortality was higher for patients with high RDW levels, at 3 months (p < 0.05), 6 months (p < 0.05), and 12 months (p < 0.05).

Conclusion: RDW is significantly related with short-term mortality in hip fracture. The higher RDW, the higher risk of mortality.

红血球分布宽度是中老年髋部骨折患者的短期死亡率预测指标。

目的：探讨中老年髋部骨折患者红细胞分布宽度（RDW）与短期死亡率的关系。方法：对一家医院2020年至2021年2年期间的电子病历进行回顾性队列分析。我们收到了233例年龄在bb0 ~ 50岁的髋部骨折患者的记录。临床资料包括患者人口统计学、入院时合并症、手术类型、血液检查、3个月死亡率、6个月死亡率和1年死亡率。分析RDW与髋部骨折短期死亡率的关系。然后根据入院时的RDW水平将队列分为两组：低RDW组结果：结果平均年龄为78.03±12.09岁；64.81%为女性。入院时，高RDW 80例（34.33%），低RDW 153例（65.67%）。两组在性别、手术类型、手术持续时间和住院时间方面无统计学差异。与低RDW水平的患者相比，高RDW患者有更多的合并症(p)。结论：RDW与髋部骨折的短期死亡率显著相关。RDW越高，死亡风险越高。

期刊介绍： BMC Musculoskeletal Disorders is an open access, peer-reviewed journal that considers articles on all aspects of the prevention, diagnosis and management of musculoskeletal disorders, as well as related molecular genetics, pathophysiology, and epidemiology. The scope of the Journal covers research into rheumatic diseases where the primary focus relates specifically to a component(s) of the musculoskeletal system.
