Effect of Hand Hygiene Intervention in Community Kindergartens: A Quasi-Experimental Study

This study aimed to evaluate the effect of hand hygiene interventions on the overall hand hygiene (HH) status of teaching instruction of hand hygiene in kindergartens, given the vulnerability of kindergarten children and their high risk due to infectious diseases and the current COVID-19 epidemic. We investigated the HH status of teachers from two kindergartens in the same community. The participants were recruited from 28 classes in both kindergartens. After completing the baseline survey, the intervention program consisted of three components: lectures on infectious diseases, lectures on HH, and seven-step hand washing techniques conducted in two kindergartens. The intervention program effectively increased teachers' perceived disease susceptibility (p < 0.05), reduced the total bacterial colonization of children's hands (p < 0.001), and improved the HH environment (p < 0.01). We recommend that health authorities or kindergartens adopt this HH intervention program to effectively improve the HH status in kindergartens and allow for preventive responses to the COVID-19 epidemic or other emerging infectious diseases.

Automated summary

This study evaluated the impact of hand hygiene interventions on the overall hand hygiene status in kindergarten teaching. The intervention program successfully increased teachers' awareness of disease susceptibility, reduced bacterial colonization on children's hands, and improved the hand hygiene environment.
