Hands4U: the effects of a multifaceted implementation strategy on hand eczema prevalence in a healthcare setting. Results of a randomized controlled trial.

ABSTRACT

BACKGROUND: Healthcare workers have an increased risk of developing hand eczema. A multifaceted implementation strategy was developed to implement a guideline to prevent hand eczema among healthcare workers. OBJECTIVES: To investigate the effects of the implementation strategy on self-reported hand eczema and preventive behaviour. METHODS: A randomized controlled trial was performed. A total of 48 departments (n = 1649) were randomly allocated to the multifaceted implementation strategy or the control group. The strategy consisted of education, participatory working groups, and role models. Outcome measures were self-reported hand eczema and preventive behaviour. Data were collected at baseline, and 3, 6, 9 and 12 months of follow-up. RESULTS: Participants in the intervention group were significantly more likely to report hand eczema [odds ratio (OR) 1.45; 95% confidence interval (CI) 1.03-2.04], and they reported significantly less hand washing (B, - 0.38; 95%CI - 0.48 to - 0.27), reported significantly more frequent use of a moisturizer (B, 0.30; 95%CI 0.22-0.39) and were more likely to report wearing cotton undergloves (OR 6.33; 95%CI 3.23-12.41) than participants in the control group 12 months after baseline. CONCLUSIONS: The strategy implemented can be used in practice, as it showed positive effects on preventive behaviour. More research is needed to investigate the unexpected effects on hand eczema.
