目的了解天津市各级医疗机构室内空气消毒效果状况。方法采用自然沉降法采样和细菌定量检测方法,对全市部分医疗机构室内空气消毒后的消毒效果进行了检测。结果从天津市各区县368家医疗机构共监测不同类别房间1 305间,总平均合格率达到91.0%。医院Ⅰ类环境空气质量合格率明显高于Ⅱ及其以下级别环境;市区及环城四区医疗机构室内空气消毒效果合格率高于郊区县医疗机构。结论天津市医疗机构室内空气消毒效果合格率较高,但郊区县医疗机构有待加强,重点改进空气消毒装置。
Objective To understand the effect of indoor air disinfection of medical institutions at all levels in Tianjin. Methods Natural sedimentation method and bacterial quantitative detection method were used to test the disinfection effect of indoor air disinfection of some medical institutions in the city. Results A total of 1 305 different types of rooms were monitored from 368 medical institutions in all districts and counties in Tianjin, with a total average passing rate of 91.0%. The qualification rate of Class I ambient air quality in hospitals was significantly higher than that in Ⅱ and below. The qualified rate of indoor air disinfection of medical institutions in urban and surrounding areas was higher than that of suburban county medical institutions. Conclusion The passing rate of indoor air disinfection in medical institutions in Tianjin is high, but the medical institutions in suburban counties need to be strengthened with a focus on improving air disinfection devices.
