目的了解掌握广州市海珠区托幼机构消毒质量情况,发现薄弱环节,提出改进措施,为卫生、教育部门管理工作提供科学依据。方法采用回顾性调查的方法,对2010-2015年辖区托幼机构室内空气、物体表面、玩具、教师手、使用中消毒剂和紫外线杀菌灯辐照强度6类监测数据进行分析。结果 6年间共监测202所托幼机构,采集监测样品14 386份,合格率为85.20%;不同样品合格率由高至低依次为使用中消毒剂(99.06%)、室内空气(96.85%)、玩具(96.05%)、物体表面(93.86%)、教师手(83.53%)、紫外线杀菌灯辐照强度(59.78%),合格率差异有统计学意义(χ~2=2308.267,P<0.05);不同规模托幼机构样品合格率差异有统计学意义(χ~2=35.500,P<0.05)。结论海珠区托幼机构消毒质量总体趋势良好,但紫外线杀菌灯辐照强度和教师手的卫生仍需提高。
Objective To understand the disinfection quality of nurseries and kindergartens in Haizhu District of Guangzhou and to find the weaknesses and propose the improvement measures to provide a scientific basis for the management of health and education departments. Methods A retrospective survey was carried out to analyze six kinds of monitoring data of indoor air, object surface, toys, teachers’ hands, disinfectants and UV germicidal lamp irradiation intensities in the area of kindergartens in 2010-2015. Results A total of 14 386 monitoring samples were collected during the six years, with a pass rate of 85.20%. The highest pass rates of different samples were 99.06% in use, 96.85% in room air, The percentages of passing rate of toy (96.05%), object surface (93.86%), teacher ’s hand (83.53%) and UV germicidal lamp (59.78%) were statistically significant (χ ~ 2 = 2308.267, P <0.05). The sample passing rate of nurseries with different scales was significantly different (χ ~ 2 = 35.500, P <0.05). Conclusion The overall disinfection quality of nurseries in Haizhu District is good, but the irradiation intensity of UV germicidal lamps and the hygiene of teachers’ hands still need to be improved.
