目的了解鹤山市托幼机构消毒质量状况及其影响因素,改进薄弱环节,提高消毒质量,控制传染性疾病流行。方法采用现场抽检方法,依据相关标准和规范对托幼机构内的室内空气、玩具、物体表面、师生手、餐具、消毒剂的卫生状况进行检测。结果 2010—2014年共采集7 902份样品,合格6 608份,合格率为83.62%;不同城乡地区合格率差异有统计学意义(χ~2=12.62,P<0.05),不同性质托幼机构合格率差异无统计学意义(χ~2=2.49,P>0.05),不同规模托幼机构合格率差异无统计学意义(χ~2=0.63,P>0.05),不同等级托幼机构合格率差异无统计学意义(χ~2=0.89,P>0.05),不同年份间的空气样品(χ~2=11.80,P<0.05)、师生手样品(χ~2=58.44,P<0.01)、餐具样品(χ~2=19.86,P<0.01)合格率差异有统计学意义。结论师生手、物体表面监测合格率较低,应针对性地开展消毒工作;托幼机构性质、规模大小、等级类型并不是消毒质量影响因素。
Objective To understand the quality of disinfection in kindergartens and nurseries of Heshan City and its influential factors, to improve the weakness, improve the quality of disinfection and control the epidemic of infectious diseases. Methods The method of on-the-spot sampling was used to detect the health status of indoor air, toys, objects, teachers and students, utensils and disinfectants in the nurseries according to relevant standards and norms. Results A total of 7 902 samples were collected from 2010 to 2014, 6 608 were eligible, with a pass rate of 83.62%. There was a significant difference in pass rates between urban and rural areas (χ ~ 2 = 12.62, P <0.05) There was no significant difference in pass rate (χ ~ 2 = 2.49, P> 0.05). There was no significant difference in qualification rate between different scale nurseries (χ ~ 2 = 0.63, P> 0.05) There was no significant difference between two groups (χ ~ 2 = 0.89, P> 0.05). The air samples in different years (χ ~ 2 = 11.80, P < , Tableware samples (χ ~ 2 = 19.86, P <0.01), the difference was statistically significant. Conclusion Teachers and students, the object surface monitoring rate is low, disinfection should be targeted; nurseries institutions nature, size, grade type is not the impact of disinfection quality.
