目的分析心肾专科医院医院感染情况,为降低医院感染及临床合理使用抗菌药物提供参考。方法回顾性分析2012-2016年郑州市第七人民医院医院感染患者病原菌分布情况,并对结果进行统计分析。结果 2012-2016年共发生医院感染1 180例,各年发病率分别为0.86%、0.92%、0.81%、0.90%、1.08%。感染发病率较高的科室依次为肾内科、ICU、心外科、心内科。医院感染主要病原菌为大肠埃希菌、铜绿假单胞菌、肺炎克雷伯菌。2012-2016年多重耐药菌中耐甲氧西林金黄色葡萄球菌(MRSA)和产超广谱β-内酰胺酶(ESBLs)病原菌的比率逐渐下降。结论医院感染发病率有增高趋势,感染率较高的科室是肾内科和ICU,主要病原菌以革兰阴性菌为主,产ESBLs病原菌和MRSA的检出率逐渐下降。
Objective To analyze the hospital infection of heart and kidney hospital and provide a reference for reducing nosocomial infection and clinical rational use of antibacterial drugs. Methods The distribution of pathogenic bacteria in nosocomial infection patients of Seventh People’s Hospital of Zhengzhou City from 2012 to 2016 was analyzed retrospectively, and the results were statistically analyzed. Results A total of 1 180 nosocomial infections occurred between 2012 and 2016, with annual incidences of 0.86%, 0.92%, 0.81%, 0.90% and 1.08%, respectively. High incidence of infection departments followed by Department of Nephrology, ICU, cardiac surgery, cardiology. The main pathogen of hospital infection is Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae. The ratio of methicillin-resistant Staphylococcus aureus (MRSA) and extended-spectrum β-lactamase (ESBLs) -producing pathogens in multidrug-resistant bacteria decreased gradually between 2012 and 2016. Conclusions The prevalence of nosocomial infections is increasing. The departments with higher infection rates are nephrology and ICU. The main pathogens are Gram-negative bacteria. The detection rate of ESBLs-producing pathogens and MRSA is gradually decreasing.
