股骨粗隆间骨折患者住院日影响因素分析

Factors Affecting Length of Hospital Stay of Patients with Intertrochanteric Fracture

目的探讨股骨粗隆间骨折患者住院日的影响因素。方法回顾性收集自2016年1月至2017年12月153例股骨粗隆间骨折患者的病例资料。分析因素包括年龄、性别、身体质量指数、骨折类型、受伤至入院时间、入院至手术时间、受伤至手术时间、手术方式、ASA分级、Charlson合并症指数(Charlson comorbidity index,CCI)、入院时血清白蛋白浓度和入院时血红蛋白浓度。结果单因素分析显示入院至手术时间、受伤至手术时间、血红蛋白浓度、血清白蛋白浓度、性别、ASA分级、CCI对住院日有明显影响。多元线性回归提示入院至手术时间(P<0.001)和CCI≥1(P=0.029)显著增加患者住院天数。结论延迟手术和CCI升高将延长粗隆间骨折患者的住院日。

Objective To evaluate the factors associated with length of hospital stay of patients with intertrochanteric fracture.Methods We retrospectively retrieved data of 153 patients with intertrochanteric fracture between January 2016 and December 2017.The data included age,gender,body mass index,fracture type,interval between fracture and admission,interval between admission and surgery,interval between fracture and surgery,surgery type,ASA grade,Charlson comorbidity index,hemoglobin level and serum albumin.Results In univariable analyses,we found interval between admission and surgery,interval between fracture and surgery,hemoglobin level,serum albumin,gender,ASA grade and Charlson comorbidity index were significantly associated with length of hospital stay.Multivariable linear regression analysis suggested interval between admission and surgery(P<0.001)and Charlson comorbidity index≥1(P=0.029)were related to increased length of hospital stay.Conclusion Delayed surgery and higher Charlson comorbidity index would extent the length of hospital stay of patients with intertrochanteric fracture.
