A Randomised Clinical Trial on the Effect of Group Education on Patients With Occupational Hand Eczema

The hypotheses of the PREVEX trial are: * Early information build on evidence-based skin-protection programmes and work-place visits with counselling in skin care, followed by telephone hotline, will give the participants increased level of knowledge concerning the treatment and prevention of OHE. * Increased level of knowledge concerning prevention and focus on skin care will have a positive impact on skin-protective behaviour and will lower the severity of HE and prevent the development of chronic eczema. * The decrease in severity of HE will decrease sick leave and keep the participants in job, or prevent job loss, or facilitate the re-entry into the workforce. * In total, the intervention will have a positive effect on health-related quality of life.
