Hands4U: a multifaceted strategy to implement guideline-based recommendations to prevent hand eczema in health care workers: design of a randomised controlled trial and (cost) effectiveness evaluation.

Background: Workers in wet work occupations have a risk for developing hand eczema. Prevention strategies exist, but compliance to the proposed recommendations is poor. Therefore, a multifaceted implementation strategy (MIS) is developed to implement these recommendations to reduce hand eczema among health care workers performing wet work.

Methods/design: This study is a randomised controlled trial in three university hospitals in the Netherlands. Randomisation to the control or intervention group is performed at department level. The control group receives a leaflet containing the recommendations only. The intervention group receives the MIS which consists of five parts: 1) within a department, a participatory working group is formed to identify problems with the implementation of the recommendations, to find solutions for it and implement these solutions; 2) role models will help their colleagues in performing the desired behaviour; 3) education to all workers will enhance knowledge about (the prevention of) hand eczema; 4) reminders will be placed at the department reminding workers to use the recommendations; 5) workers receive the same leaflet as the control group containing the recommendations. Data are collected by questionnaires at baseline and after 3, 6, 9 and 12 months. The primary outcome measure is self-reported hand eczema. The most important secondary outcome measures are symptoms of hand eczema; actual use of the recommendations; sick leave; work productivity; and health care costs.Analyses will be performed according to the intention to treat principle. Cost-effectiveness of the MIS will be evaluated from both the societal and the employer's perspective.

Discussion: The prevention of hand eczema is important for the hospital environment. If the MIS has proven to be effective, a major improvement in the health of health care workers can be obtained. Results are expected in 2014.
