Hand hygiene compliance and environmental determinants in child day care centers: An observational study

摘要

Background: Children attending day care centers (DCCs) are at high risk for contracting infections, for which hand hygiene (HH) is an effective prevention measure. The study objectives were to assess caregivers' compliance to HH guidelines in DCCs and to identify environmental determinants of HH behavior. Methods: We observed caregivers' compliance to HH guidelines and collected data on environmental determinants (ie, number of sinks, number and type of towel and soap facilities, availability of alcohol-based hand sanitizers). Using multilevel logistic regression analyses, odds ratios (OR) with 95% confidence intervals (CI) were obtained for environmental determinants of HH behavior. Results: In 122 participating DCCs, 350 caregivers and 2,003 HH opportunities were observed. The overall compliance was 42% (95% CI: 40%-44%). Compliance for different activities for which HH was indicated ranged from 20% to 79%. In the multivariable model, the number of towel facilities per caregiver (OR, 2.33; 95% CI: 1.40-3.88) and type of towel facilities were significantly associated with HH. Hands were most frequently washed when only paper towels were available compared to only fabric towels (OR, 1.47; 95% CI: 1.00-2.16) or a combination of both paper and fabric towels (OR, 2.13; 95% CI: 1.32-3.44). Conclusion: HH compliance of caregivers in Dutch child DCCs can be improved. Interventions for this should take into account environmental determinants such as the number and type of towel facilities.
