急诊危重症患者院内鲍曼不动杆菌感染的危险因素Logistic回归分析

Logistic regression analysis of risk factors for Acinetobacter baumannii nosocomial infection in emergency critically ill patients

目的对急诊危重症患者院内鲍曼不动杆菌感染的危险因素进行Logistic回归分析。方法将我院急诊科2016年1月至2017年12月收治的380例危重症患者的临床资料进行回顾性分析,探讨院内鲍曼不动杆菌感染的危险因素。结果感染率为11.05%,感染组年龄>80岁、伴有免疫功能障碍、伴有低蛋白血症、住ICU时间>7 d、有侵袭性操作、使用免疫抑制剂、抗生素使用种类>2种的构成比均高于非感染组(P<0.05),且经Logistic回归分析均为独立危险因素(OR=6.143、3.974、4.028、2.962、9.876、3.244、8.072,P<0.05)。结论年龄>80岁、伴有免疫功能障碍、伴有低蛋白血症、住ICU时间>7 d等均为急诊危重症患者院内鲍曼不动杆菌感染的危险因素。

Objective To carry out the Logistic regression analysis of risk factors for Acinetobacter baumannii nosocomial infection in emergency critically ill patients. Methods The clinical data of 380 critically ill patients admitted to the emergency department of our hospital from January 2016 to December 2017 were retrospectively analyzed, and the risk factors for Acinetobacter baumannii nosocomial infection were discussed. Results The infection rate was 11.05%. The rates of age 80, with immune dysfunction, with hypoproteinemia, living in ICU time 7 d, had invasive operation, use of immunosuppressive agents, and antibiotic use species 2 in the infection group were higher than those in the non infection group（P〈0.05）, which were independent risk factors by Logistic regression analysis（OR=6.143, 3.974, 4.028, 2.962, 9.876,3.244, 8.072, P〈0.05）. Conclusion Age 80, with immune dysfunction, with hypoproteinemia, living in ICU time 7 d and so on are the independent risk factors of Acinetobacter baumannii nosocomial infection in emergency critically ill patients.
