Epidemiological characteristics of geriatric hip fracture in Beijing: a multicenter analysis of 2,071 cases / 中华创伤骨科杂志

ABSTRACT

Objective:To explore the epidemiological characteristics of geriatric hip fractures in Beijing so as to provide evidence for effective prevention and control measures.Methods:This multicenter study was conducted in 3 urban (Beijing Jishuitan Hospital, Beijing Hospital and Beijing Anzhen Hospital) and 3 suburban hospitals (Beijing Shunyi District Hospital, Beijing Changping District Hospital and Beijing Liangxiang Hospital) in Beijing from November 2018 to November 2019. Eligible patients were those aged ≥ 65 years with hip fracture confirmed by X-ray and being admitted to hospital within 21 days of injury. To explore the epidemiological characteristics of geriatric hip fractures in Beijing, such data were collected as patients' age, gender, comorbidities, as well as type, site, time and cause of the fracture.Results:① A total of 2,071 patients were included in this suevey. They were 653 males and 1,418 females (M∶F=1∶2.17). Their age ranged from 65 to 102 years (average, 79.8 years). The patients aged from 75 to 84 years were the most common, accounting for 44.81% (928/2,071). ② Femoral neck fractures accounted for 43.41% (899/2,071), and intertrochanteric fractures accounted for 56.59% (1,172/2,071). The age of the patients with femoral neck fracture was (78.6±7.7) years, which was significantly younger than that of those with intertrochanteric fracture [(80.7±7.4) years] ( P<0.05). ③ 94.69% of the hip fractures (1,961/2,071) were caused by falling, and 71.27% fractures (1,476/2,071) happened at home. ④ Approximately 83.00% of the patients (1,719/2,071) had one or more comorbid conditions. Hypertension was the most prevalent disease (57.89%, 1,199/2,071), followed by diabetes (27.09%, 561/2,071), and coronary atherosclerotic heart disease (22.02%, 456/2,071). Conclusions:In Beijing, significantly more geriatric females sustain a hip fracture than males, and the proportion of those aged from 75 to 84 year is the largest. The proportion of intertrochanteric fractures increases with age. Falls are the leading cause for geriatric hip fractures. Most of the patients have one or more chronic comorbid conditions. Corresponding prevention and intervention measures should be formulated according to the distribution characteristics of elderly hip fractures in Beijing.
