Objective To investigate the basic situation of healthcare-associated in lection (HAD in a tumor hospital, so as to provide reference for the surveillance of HAI. Methods According to the requirements of the National HAI Surveillance Network, on August 31, 2011, a survey on HAI prevalence rate among all hospitalized patients in this hospital were carried out, data were statistically analyzed. Results A total of 737 patients were surveyed, 36 HAI cases occurred, the prevalence rate was 4. 88% ; lower respiratory tract was the main infection site, accounting for 38. 89% ( 14/36%) ; daily antimicrobial usage rate was 21. 30 %( 157/737) , pathogenic detection rate in patients receiving therapeutic antimicrobial use was 74. 29% (78/105); 27 pathogens were detected in patients with HAI, 74. 07% (20/27) of pathogens were gram-negative strains, 7 Escherichia colt isolates were multidrug-resistant strains. Conclusion Survey of HAI prevalence rate can realize the occurrence of HAI in specialty hospitals, promote the implementation of measures on prevention and control of HAI, and effectively reduce HAI rate.%目的 了解某省级肿瘤医院医院感染基本情况,为开展医院感染监控工作提供依据.方法 按全国医院感染监测网要求,对该院2011年8月31日0-24时的所有住院患者进行医院感染现患率调查,并对数据进行统计处理.结果 共调查住院患者737例,发生医院感染36例,医院感染现患率为4.88%;下呼吸道是医院感染的主要部位,占38.89%(14/36);调查日抗菌药物使用率为21.30%(157/737),治疗用药病原学送检率为74.29%(78/105);医院感染患者检出病原菌27株,以革兰阴性菌为主(占74.07%,20/27),其中7株大肠埃希菌为多重耐药菌.结论 通过医院感染现患率调查,可了解专科医院医院感染发生情况,以便针对性地开展防控措施,有效降低医院感染率.
