西安市莲湖区托幼机构保育老师消毒知识知晓与消毒质量分析

Abstract: Objective To understand the awareness of disinfection knowledge among childcare teachers and the effectiveness of preventive disinfection in childcare institutions in Lianhu District, Xi’an, analyze existing problems, and propose improvement measures. Methods Random sampling was conducted across different levels of childcare institutions. A survey on disinfection knowledge awareness was administered to childcare teachers (418 participants in total), and disinfection effectiveness was monitored through on-site sampling, covering environmental surfaces, staff hands, and indoor air. Results Childcare workers demonstrated good awareness of “using running water for handwashing” but their understanding of “whether large-scale outdoor disinfection should be performed” was relatively poor. There were statistically significant differences in disinfection knowledge scores among childcare workers of different ages and kindergarten levels. A total of 751 samples were collected, with a qualification rate of 92.28%. Among them, the qualification rate for staff hands was the lowest, while that for tableware was the highest. The disinfection qualification rate in kindergartens rated Level 2 or above (93.36%) was higher than that in kindergartens below Level 2 (88.29%). Kindergartens with better awareness of disinfection knowledge had a higher qualification rate (95.77%) compared to those with poorer awareness (90.15%). Conclusion Childcare workers in kindergartens in Lianhu District generally demonstrated good knowledge of disinfection, though some misconceptions remained. The overall disinfection effectiveness was satisfactory, but hand hygiene among staff required further improvement. To ensure optimal disinfection outcomes, it is recommended to moderately increase relevant training to safeguard children’s health.
