河南某三级医院住院患者医院感染情况调查

Investigation on nosocomial infection of a tertiary hospital in Henan province

目的了解某三级综合医院住院病人医院感染发生的特点及相关因素,提出相应防控对策。方法采用前瞻性调查方法,对河南某三级综合性医院2013年9月所有住院患者医院感染发生率及其临床分布进行监测。结果该医院2013年9月共监测住院患者6 180例,发生医院感染患者68例、71例次,医院感染月发病率为1.10%、例次感染率为1.15%。月感染发病率≥8.0%的病区分别是儿科重症监护室、呼吸科重症监护室、综合重症医学科、神经科重症监护室。感染部位以下呼吸道感染为主,其次为泌尿系统感染。共培养出病原菌352株,革兰阴性杆菌占64.2%,鲍曼不动杆菌、铜绿假单胞菌、大肠埃希菌、肺炎克雷伯菌和金黄色葡萄球菌为优势菌群。结论该医院住院病人医院感染主要集中在各重症监护病房,主要防护对策是减少侵入性操作和加强病原学监测及药敏试验。
