目的分析珠海市医院空气消毒监测数据,发现存在的问题,提出改进措施。方法利用2009-2012年珠海市医院空气消毒效果监测资料,计算并比较珠海市不同级别医院以及不同环境类型的空气合格率。结果珠海市三级、二级、一级医院空气合格率分别是48.18%、74.19%、83.59%,三级和一二级医院差异有统计学意义(χ2=37.108,P<0.05);Ⅰ、Ⅱ、Ⅲ类环境空气合格率分别是37.37%、82.22%、64.71%,Ⅰ类和ⅡⅢ类环境空气差异有统计学意义(χ2=55.316,P<0.05)。多因素分析显示,三级医院Ⅰ类环境和Ⅱ类环境空气合格率明显低于一二级医院。结论珠海市三级医院空气合格率低可能与消毒管理等因素有关,建议医院要加强空气消毒管理力度。
Objective To analyze the data of air disinfection monitoring in Zhuhai Hospital and find out the existing problems and put forward the improvement measures. Methods According to the air disinfection monitoring data of Zhuhai Hospital from 2009 to 2012, the air pass rates of hospitals of different grades and different types of environment in Zhuhai were calculated and compared. Results The air pass rates of the third, second and first grade hospitals in Zhuhai were 48.18%, 74.19% and 83.59% respectively. There were significant differences between the third and the first and second level hospitals (χ2 = 37.108, P <0.05) The pass rates of Class II and Class III ambient air were 37.37%, 82.22% and 64.71%, respectively. There were significant differences in the ambient air between Class I and Class II (χ2 = 55.316, P <0.05). Multivariate analysis showed that the qualified rate of Class I environment and Class II ambient air in tertiary hospitals was significantly lower than that of primary and secondary hospitals. Conclusions The low pass rate of air in tertiary hospitals in Zhuhai may be related to factors such as disinfection management. It is suggested that hospitals should strengthen the management of air disinfection.
