目的了解许昌市医疗机构消毒质量,为提高消毒质量,预防控制医院感染提供依据。方法对许昌市医疗机构2014-2017年消毒质量监测结果进行统计分析。结果4年共采样3641份,合格3505份,合格率96.26%;2014-2017年合格率分别为93.34%、95.65%、97.73%和98.63%,呈逐年上升趋势,差异有统计学意义(趋势χ^2=41.435,P<0.05)。灭菌器、内镜和污水合格率最高,均为100%;医疗用水合格率最低,为83.10%;物体表面和消毒剂合格率较低,分别为98.67%和97.58%。不同年份物体表面和医疗用水合格率差异均有统计学意义(χ^2=10.137,P<0.05;χ^2=19.622,P<0.05),不同级别医疗机构合格率差异有统计学意义(χ^2=116.7,P<0.05)。结论许昌市医疗机构消毒质量整体较好,但仍然存在部分问题,特别是物体表面和医疗用水需要进一步加强消毒监测和管理工作。

Objective To understand the disinfection quality in medical institutions in Xuchang,and to provide evidence for improving the disinfection quality and preventing and controlling nosocomial infections.Methods Statistical analysis was carried out on the results of disinfection quality monitoring of medical institutions in Xuchang from 2014 to 2017.Results A total of 3641 samples were collected in 4 years,and 3505 samples were qualified,with a qualified rate of 96.26%;the qualified rates from 2014 to 2017 were 93.34%,95.65%,97.73%and 98.63%,respectively,showing an increasing trend year by year,and the difference was statistically significant(Linear trendχ^2=41.435,P<0.05).The qualified rates of sterilizer,endoscope and sewage were the highest(100%),and the qualified rate of medical water was the lowest(83.10%).Secondly,the qualified rates of object surfaces and disinfectants were lower,98.67%and 97.58%respectively.There were significant differences in the qualified rates of object surface and medical water in different years(χ^2=10.137,P<0.05;χ^2=19.622,P<0.05).The difference of the qualified rate of medical institutions at different levels was statistically significant(χ^2=116.7,P<0.05).Conclusion The disinfection quality of medical institutions in Xuchang city is generally good,but there are still some problems,especially the disinfection monitoring and management of object surface and medical water need to be further strengthened.
