老年患者髋部骨折术后1年病死率及危险因素分析:一项回顾性队列研究

目的 调查老年髋部骨折患者术后1年病死率,并分析其危险因素. 方法 研究为回顾性队列研究,收集2011年～2014年因髋部骨折行手术治疗的老年(年龄≥65岁)患者信息,随访术后1年存活情况,采用Logistic回归分析筛选术后死亡的危险因素. 结果 共295名老年髋部骨折患者纳入本研究,平均年龄(78.4±6.7)岁,女性占71.5％,术前有3种以上合并症的占38％,平均随访(31.2±0.7)个月.住院期间、术后30 d、术后1年以及随访结束时病死率分别为0.7％、1.7％、3.7％和5.8％. 结论 高龄、术前合并呼吸系统疾病、既往有脑卒中病史及采用内固定手术是老年髋部骨折患者术后1年死亡的危险因素.

Risk factors of one-year mortality in elderly patients after hip fracture surgery: a retrospective study

Objective To investigate the 1-year mortality rate in elderly patients after hip fracture surgery,and to identify the risk factors of this 1-year mortality.Methods This was a retrospective cohort study.Elderly patients (aged ≥ 65 years) who underwent hip fracture surgery from May 2011 to May 2014 were consecutively enrolled.Patients were followed-up for 1-year survival.Logistic regression analyses were performed to identify risk factors of 1-year mortality.Results A total of 295 patients were enrolled in the study.The mean age was (78.4±6.7) y,the percentage of female patients was 71.5％,the percentage of patients with more than 3 comorbidities was 38％,and the mean follow-up duration was (31.2±0.7) months.The mortality rate during hospitalization and at 30 d and one year after surgery was 0.7％,1.7％ and 3.7％,respectively.Conclusions Our study showed that,in elderly patients undergoing hip fracture surgery,older age,preoperative respiratory diseases,previous history of stroke and internal fixation were associated with high 1-year mortality.
