目的探讨监测病原菌实施感染控制措施的效果。方法通过LIS系统对住院患者每日的病原菌发生情况进行监测,判断是否有暴发趋势;对住院>30 d的患者每月进行病原菌监测,查看是否有反复感染的发生;对多药耐药菌感染或定植患者实行接触隔离措施,并追踪与其接触过的其他患者感染情况;怀疑有暴发趋势时进行环境卫生学监测。结果 421例病原菌阳性报告中引起医院感染的58株,24株多药耐药菌,15例住院>30 d的患者发生反复感染;对24例多药耐药感染或定植患者实施接触隔离后未发生院内传播;ICU内共采集10份物体表面样本、13份手样本和13份鼻前庭样本进行环境卫生学监测,其中4名医务人员有MRSA定植,治疗后复查,未再检出病原菌;2009年医院感染发生率为1.7%,比2008年下降了0.8%。结论通过监测病原菌,实施针对性干预措施,可以减少医院感染的发生,及时遏制感染暴发。
Objective To explore the effect of monitoring pathogen infection control measures. Methods The incidence of pathogenic bacteria in hospitalized patients was monitored by LIS system to determine whether there was an outbreak. Pathogens were monitored monthly for patients who were hospitalized for more than 30 days to find out whether there was recurrent infection or not. Or colonization patients to implement contact isolation measures, and follow-up contact with other patients with infection; suspected environmental outbreaks of environmental hygiene monitoring. Results In the positive reports of 421 pathogens, 58 hospital-acquired infections, 24 multidrug-resistant bacteria and 15 hospitalized> 30 d patients were recurrent infections. After 24 patients with multi-drug resistant infection or colonization were not isolated after contact isolation There were 10 surface samples collected in the ICU, 13 hand samples and 13 samples of nasal vestibules for environmental hygiene monitoring. Among them, 4 medical staff were colonized with MRSA, and after treatment, no pathogen was detected again. The annual hospital infection rate was 1.7%, down 0.8% over 2008. Conclusion By monitoring pathogenic bacteria and implementing targeted interventions, the incidence of nosocomial infections can be reduced and the outbreak of infection can be stopped in time.
