A long‐term follow‐up study of the Hand Eczema Trial (HET): a randomized clinical trial of a secondary preventive programme introduced to Danish healthcare workers

Preventive skin care programmes have shown beneficial effects on the prevalence and severity of hand eczema, but most trials only report short‐term outcomes. One such trial was the randomized Hand Eczema Trial (HET, 2009) investigating the effects of a secondary prevention programme in healthcare workers. Positive results have been reported at 5‐month follow‐up.
