Risk factors of Acinetobacter Baumann ii nosocomial infection in ICU and respiratory department

Objective To study the risk factors of nosocomial infection with Acinetobacter baumannii (AB). Methods The clinical data of 6 017 patients in ICU and respiratory department (RD) were retrospectively analyzed to understand the cross infection rate and risk factors with AB nosocomial infection, and we provide a theoretical basis for hospital infection control. Results There were 5 002 cases in RD, the infection rate was 0.59% (30 cases), 1 015 cases in ICU and the infection rate was 19.70% (200 cases). The infection rate of ICU was significantly higher than RD ( P 0.05); But whether or not there were basic diseases, the infection rate in ICU was significantly higher than in RD ( P 0.05) , 但无 论是否有基础疾病, 在 ICU 感染率均高于呼吸科, 差异有统计学意义, ( P <0.05)。同样使用广谱抗生素治疗, 在 ICU 感 染率高于呼吸科, 差异有统计学意义 ( P <0.05)。 结论 “气道开放”是院内感染 AB 的关键环节, “广谱抗生素治疗”、“合 并基础疾病”是防控鲍曼不动杆菌感染的重要环节, 应针对性管理, 尤其是 ICU。
