鲍曼不动杆菌医院感染危险因素Logistic回归分析

Logistic Regression Analysis of Acinetobacter Baumannii Hospital Infection Risk factors

目的：探讨我院住院病人鲍曼不动杆菌（Acinetobacterbaumannii）医院感染的相关因素。方法：前瞻性研究我院2009—2010年住院病人，以病例对照的方法研究其危险因素，并进行多因素分析。结果：共研究2909人，其中鲍曼不动杆菌感染有68人，感染率为2．28％；发病密度为3．42／1000住院日。主要感染部位是呼吸道感染26（38．24％）人、血流感染22（32。35％）人、尿路感染10（14．71％）人、手术部位感染7（10．29％）人、其他部位感染3（4．41％）人。其中对亚胺培南耐药的AB菌感染12（17．65％）人。经Logistic回归分析动静脉导管、使用鼻胃管、呼吸器、导尿管是主要危险因素。结论：鲍曼不动杆菌医院感染以呼吸道最多，所有鲍曼不动杆菌医院感染与多种侵入性操作密切相关，落实有关侵入性操作曲崴婆控制指南暑预防鲍晕不劫轩菌庸染与格傲的量垂措施．

Objective： Study relevant factors of Acinetobaeter baumannii hospital infection of the hospitla inpatients. Methods： Prospective study inpatients in 2009 and in 2010 in the hospital. Adopt the method of case--control to study risk factors,analyzing multi--factors. Results： 2909 patients were studied,68 patients infected by Acinetohaeter baumannii,infection rate 2.28% ,incidence density 3.42/1000 length of stay. Pnmary sites of infection included： 26 patients （38.24%） respiratory infection, 22 patients （32.35%） bloodstream infections, 10 patients （14.71 %） urinary tract infection,7 patients（10.29%） surgical site infection,3 patients（4.41%）other parts of the infection. 12 patients（17.65%）were infected by AB bacteria of Imipenem Resistance. Venous catheter, using of nasogastric tube, respirator and catheter were major risk factors,analyzed by Logistic Regression A- nalysis. Conclusion：In Acinetobacter baumannii hospital infection,respiratory was most. All Acinetobacter baumannil hospital infection and variety of invasive procedures were related closely. Implementing Infection Control Guidelines of relating invasive procedures was important measure to prevent Acinetobacter baumannii infection and spreading.
