The aim of this study is to value whether patients who have suffered a hip fracture have a higher mortality than expected.
A prospective, observational study was carried out where patients with hip fracture were collected as a sample over a year. The study included 284 patients and a minimum follow-up was 2 years. The mean age of these patients was 84.26 years, with 21.48% (61/284) males and 78.5% (223/284) females. Survival and previous diseases that affect mortality, as risk factors, were collected and analyzed using the Kaplan-Meier method and the Cox regression model. Actual mortality was compared with that expected according to the Charlson Comorbidity Index, adjusted for age.
Previous pathology was the main mortality factor, with heart disease being the most significant (OR 1.817, CI95%: 1.048; 3.149). The real mortality at one year of the sample was 22.5%, while the estimated annual mortality according to the Charlson Comorbidity Index was 29.68% (CI95%:44,36-15).
Hip fracture does not cause an increase in mortality according to the Charlson Comorbidity Index estimate.
本研究旨在评估髋部骨折患者的死亡率是否高于预期。
进行了一项前瞻性、观察性研究，在一年的时间里收集了髋部骨折患者作为样本。该研究纳入了 284 名患者，随访时间至少为 2 年。这些患者的平均年龄为 84.26 岁，其中男性占 21.48%（61/284），女性占 78.5%（223/284）。收集并分析了与死亡率相关的生存情况和既往影响死亡率的疾病等风险因素，使用 Kaplan-Meier 方法和 Cox 回归模型进行分析。根据 Charlson 合并症指数，调整年龄后，将实际死亡率与预期死亡率进行比较。
既往病史是主要的死亡因素，心脏病是最显著的（OR 1.817，95%CI：1.048；3.149）。样本一年时的实际死亡率为 22.5%，而根据 Charlson 合并症指数估计的年死亡率为 29.68%（95%CI：44，36-15）。
根据 Charlson 合并症指数的估计，髋部骨折并不会导致死亡率增加。
