目的了解住院患者医院感染现状,研究医院感染高危科室分布,为采取重点防控措施提供依据。方法采用回顾性调查方法,对某医院连续4年住院患者医院感染情况进行调查与分析。结果连续4年共调查该医院住院患者246 736例,2010-2013年各年度医院感染发生率分别是1.55%、1.74%、1.51%和1.09%。感染率较高的科室是心胸外科和神经外科,感染部位以呼吸道为主,下呼吸道占39.52%,上呼吸道占29.77%。检出病原菌982株,居前3位的分别是大肠埃希菌、铜绿假单胞菌和鲍曼不动杆菌。结论该医院感染高危科室是心胸外科和神经外科,应将其列为重点防范科室,加强呼吸道感染防控。
Objective To understand the current status of nosocomial infection in hospitalized patients and to study the distribution of nosocomial infection-prone departments in order to provide the basis for prevention and control measures. Methods The retrospective investigation method was used to investigate and analyze the hospital infection of hospitalized patients in a hospital for 4 consecutive years. Results A total of 246 736 inpatients were investigated in this hospital for four consecutive years. The prevalence rates of nosocomial infections in each year from 2010 to 2013 were 1.55%, 1.74%, 1.51% and 1.09%, respectively. Department of higher rates of infection is cardiothoracic surgery and neurosurgery, the main respiratory tract infection, accounting for 39.52% of the lower respiratory tract, upper respiratory tract accounted for 29.77%. 982 pathogens were detected, the top three are Escherichia coli, Pseudomonas aeruginosa and Acinetobacter baumannii. Conclusion The high risk department of hospital infection is cardiothoracic surgery and neurosurgery, it should be listed as a key prevention department, to strengthen prevention and control of respiratory infections.
