2011～2013年某中医医院感染现患率调查分析

Prevalence Rate of Nosocomial Infection of a Chinese Medicine Hospital from 2011 to 2013

目的：了解某中医医院感染现患率情况，为有效预防及控制医院感染提供依据。方法：按照四川省医院感染监测网制定的全省医院感染现患率调查方案，采取横断面调查的方法，调查该院2011年9月1日、2012年8月16日、2013年7月11日全院所有住院患者感染现患率，并对2011-2013年医院感染现患率调查资料进行统计分析。结果：该院2011-2013年医院感染现患率分别：3.30%、2.27%、2.26%，差异有统计学意义（P＜0.05）。医院感染部位以下呼吸道居首位，占46.15%，其次为泌尿道（19.23%）、手术切口（11.54%）和胃肠道（11.54%）。医院感染病原体共检出20株，其中前四位分别为：肺炎克雷伯菌8株占40.00%，铜绿假单胞菌4株占20.00%，鲍曼不动杆菌3株占15.00%，金黄色葡萄球菌3株占15.00%，其余嗜麦芽窄食单胞菌1株占5%，大肠埃希菌1株占5%。2011-2013年抗菌药物使用率分别为45.87%、38.70%、37.57%；病原学送检率分别为57.55%、63.11%、62.50%。结论：通过3年现患率调查，做到及时掌握全院医院感染发生的现状，明确医院感染的相关危险因素，医院针对重点科室及重点部位，开展了目标性监测与干预，医院感染现患率呈下降趋势，提高全院医务人员感染控制意识，减少院感暴发流行的发生，为制定院内感染控制措施提供了有力的依据，保障了医疗安全。

Objective： To investigate the prevalence rate of nosocomial infection（NI） in a Chinese medicine hospital, so as to provide reference for making NI control measures. Methods：According to the investigation plan of nosocomail infection rates made by nosocomail infection monitoring network of Sichuan province, the cross-sectional survey on NI was carried out among all patients hospitalized on September 1st,2011, August 16th,2012 and July 11th,2013. The survey data of prevalence rate of NI from 2011 to 2013 was analyzed. Results： The prevalence rate of NI from 2011 to 2013 was 3.30%, 2.27% and 2.26% respectively. The difference was statistically significant （P＜0.05 ）. The top infection site was lower respiratory tract（46.15%）,followed by urinary tract（19.23%）,surgical incision（11.54%） and gastrointestinal tract（11.54%）. A total of 20 pathogenic strains were detected. The top four were klebsiella pneumoniae, pseudomonas aeruginosa, acinetobacter baumannii, staphylococcus aureus which were 8（40.00%）,4（20.00%）,3（15.00%） and 3（15.00%） isolates respectively.. What’s more, each of stenotrophomonas maltophilia and escherichia coli was 1（5.00%）. . The usage rate of antibiotics from 2011 to 2013 were 45.87%, 38.70%, 38.70% and etiology inspection rate were 63.11% 57.55% and 63.11%respectively. Conclusion： Through the 3-year prevalence rate investigation, in order to control the present situation of nosocomial infection in the hospital at once, and find out the related risk factors for the infection, the hospital carried out the targeted monitoring and intervention to the key departments and key parts. In this way, the infection rate tended to decline. It raised the staff’s awareness of infection-control and reduced the chance of infectious diseases outbreak in the hospital. It also provided a powerful basis for making plan for the hospital infection-control and ensured the medical safety.
