目的分析影响ICU病死率的常见因素。方法采集该院ICU住院患者191例常用临床指标25项数据,进行二元logistics回归、ROC曲线、Kaplan-Meier生存曲线分析。结果经logistic回归分析,大血小板比率(P<0.03)、微量白蛋白尿(P<0.022),是影响ICU病死率的重要因素。红细胞分布宽度、血清白蛋白浓度、血肌酐、血清钠离子、血红蛋白浓度、大血小板比率、微量蛋白尿7项因子乘积对病死率做ROC曲线分析(P<0.04)。血清钠离子及微量蛋白尿乘积ROC曲线分析(P<0.008)。结论大血小板比率、微量蛋白尿、血清钠离子及微量蛋白尿乘积是影响ICU病死率的重要危险因素;肌酐、血清钠离子、大血小板比率、血红蛋白、血清白蛋白、红细胞分布宽度7项因子乘积是影响ICU病死率的独立危险因素。
Objective To analyze the common factors affecting the mortality of ICU. Methods Ninety-one clinical data of 191 inpatients with ICU in our hospital were collected and analyzed by binary logistic regression, ROC curve and Kaplan-Meier survival curve. Results Logistic regression analysis showed that the large platelet ratio (P <0.03) and microalbuminuria (P <0.022) were the important factors influencing the mortality of ICU. The distribution of erythrocyte width, serum albumin concentration, serum creatinine, serum sodium, hemoglobin concentration, large platelet ratio, microalbuminuria 7 factor product ROC curve analysis of mortality (P <0.04). Serum sodium and microalbumin product ROC curve analysis (P <0.008). Conclusions The large platelet ratio, microalbuminuria, serum sodium and trace proteinuria are the important risk factors affecting the mortality of ICU. The product of creatinine, serum sodium, large platelet ratio, hemoglobin, serum albumin, Is an independent risk factor affecting the mortality rate of ICU.
