鲍曼不动杆菌医院感染危险因素分析

Analysis of risk factors for nosocomial infection of Acinetobacter baumannii

目的分析鲍曼不动杆菌医院感染的危险因素,为制订医院感染的防控措施提供依据。方法回顾性分析2019年1—12月台州恩泽医疗中心(集团)恩泽医院感染科1272例患者的临床资料,调查鲍曼不动杆菌医院感染发生率,将发生鲍曼不动杆菌医院感染者作为感染组,其他患者作为非感染组,分析患者发生鲍曼不动杆菌医院感染的危险因素。结果在本次调查期间,共调查1272例患者,发生鲍曼不动杆菌感染48例,发病率为3.77%。单因素分析显示,年龄、联合应用广谱抗菌药物、留置胃管/尿管、深静脉置管、机械通气及住院时间是鲍曼不动杆菌感染的危险因素。多因素logistic回归分析发现,联合应用广谱抗菌药物、深静脉置管、机械通气、住院时间是鲍曼不动杆菌感染的独立危险因素。结论感染科患者鲍曼不动杆菌感染的危险因素较多,要采取有针对性的综合干预措施进行防控。

Objective To analyze the risk factors of nosocomial infection of Acinetobacter baumannii,so as to provide a basis for the development of prevention and control measures of nosocomial infections.Methods The clinical data of 1272 patients in the department of infection in Enze Hospital of Taizhou Enze Medical Center(Group)from January to December 2019 was retrospectively analyzed.The incidence of nosocomial infection of Acinetobacter baumannii was investigated.Those who suffered from nosocomial infection of Acinetobacter baumannii were selected as the infection group and other patients were selected as the non-infection group.The risk factors forthe occurrence of nosocomial infection of Acinetobacter baumannii were analyzed.Results During this investigation,a total of 1272 patients were investigated and 48 patients suffered from Acinetobacter baumannii infection,with an incidence rate of 3.77%.Singlefactor analysis showed that age,combined application of broad-spectrum antibacterials,indwelling gastric/urinary catheter,deep venous catheterization,mechanical ventilation and length of stay were risk factors for Acinetobacter baumannii infection.Multi-factor logistic regression analysis revealed that combined application of broad-spectrum antibacterials,deep venous catheterization,mechanical ventilation and length of stay were independent risk factors for Acinetobacter baumannii.Conclusion There are various risk factors for Acinetobacter baumannii infection in patients of thedepartment of infection,and targeted comprehensive inter ventions should be adopted for prevention and control.
