Comorbidities affect outcome, but there is no consensus which comorbidity instrument is best in orthopedic surgery. We assessed whether the American Society of Anesthesiologists Physical Status score (ASA) predicts long-term mortality after hip fracture. We followed 1635 patients for 5 to 10 years after operative treatment of hip fracture. Unadjusted Kaplan-Meyer statistics indicated that the overall survival of the patients was 4.7 (95% confidence interval [CI], 4.5-4.9) years, but survival varied significantly between the ASA groups. Survival for ASA 1 was 8.5 years (95% CI, 7.8-9.2); for ASA 2, it was 5.6 years (95% CI, 5.3-5.9); for ASA 3, it was 3.5 years (95% CI, 3.2-3.7); and for ASA 4, survival was 1.6 years (95% CI, 1.0-2.1). The ASA predicts long-term mortality after hip fracture treatment.
合并症会影响预后，但在矫形外科中，哪种合并症评估工具最佳尚无共识。我们评估了美国麻醉医师协会身体状况评分（ASA）是否能预测髋部骨折患者的长期死亡率。我们对 1635 例接受髋部骨折手术治疗的患者进行了 5 至 10 年的随访。未调整的 Kaplan-Meier 统计表明，患者的总体生存率为 4.7 年（95%置信区间[CI]，4.5-4.9），但 ASA 组之间的生存率差异显著。ASA 1 组的生存率为 8.5 年（95%CI，7.8-9.2）；ASA 2 组为 5.6 年（95%CI，5.3-5.9）；ASA 3 组为 3.5 年（95%CI，3.2-3.7）；ASA 4 组的生存率为 1.6 年（95%CI，1.0-2.1）。ASA 可预测髋部骨折治疗后的长期死亡率。
