目的研究医院血液病房环境与诊疗用水中真菌污染状况,分析环境控制措施对医院真菌感染的防控效果。方法通过对医院环境标本细菌检测的方法和医院感染监测方法,对江苏省8所医院血液病房真菌污染现状和医院真菌感染率进行监测与分析。结果共检测空气标本462份,其中真菌采集阳性数为394份,空气中真菌检出率为85.28%;检测物体表面标本1 316份,其中真菌采集阳性数为1 056份,物体表面真菌检出率为80.24%;52份诊疗用水中未检出真菌。2014年和2015年住院患者真菌医院感染发生率分别为1.15%和2.43%。医院血液病房主要采用空气净化消毒装置、自然通风措施和紫外线灯照射消毒等空气消毒措施。结论本次所调查的江苏省8所医院血液病房环境中真菌污染严重,控制措施效果不佳,真菌感染处于增加趋势。
Objective To study the status of fungal contamination in hospital blood ward environment and clinic water and to analyze the prevention and control effect of environmental control measures on hospital fungal infection. Methods By means of the method of bacterial detection in hospital environmental specimens and the monitoring method of nosocomial infection, the status of fungal contamination in the blood wards of 8 hospitals in Jiangsu Province and the prevalence of nosocomial fungi infection were monitored and analyzed. Results A total of 462 air samples were detected, of which 394 were positive for fungus collection and 85.28% for fungi in air samples. 1 316 were detected on the surface of the samples, of which 1056 were positive for fungus collection. The rate was 80.24%. No fungi were detected in 52 medical water samples. The prevalence of hospital-acquired fungal nosocomial infections in 2014 and 2015 were 1.15% and 2.43%, respectively. Blood hospital ward mainly used air purification and disinfection devices, natural ventilation and UV disinfection of air disinfection measures such as disinfection. Conclusion The fungal contamination in blood ward environment of 8 hospitals in Jiangsu Province investigated in this investigation is very serious, and the control measures are not effective and the fungal infection is on the rise.
