Abstract
Background: Hand eczema (HE) is common among hospital cleaners, yet no specific prevention programme exists for this group in Denmark.
Objectives: To evaluate the effectiveness of visual aids (pictograms and video scenes) based on evidence-based skin care and protection recommendations on HE outcomes, focusing on disease severity, point prevalence and skin care and protection knowledge.
Methods: A cluster-randomised controlled trial was conducted in professional cleaners from three Danish hospitals. Intervention Group A received pictograms, video clips and a short group-based educational session. Intervention Group B received only pictograms and video clips. The control group received treatment as usual. HE severity and prevalence were assessed clinically, while knowledge was measured using self-reported data.
Results: Out of 234 invited cleaners, 224 (96%) participated (Intervention Group A: 73, Intervention Group B: 78, Control Group: 73). After 24 weeks, both intervention groups showed significant reductions in HE severity and prevalence compared to the control group. Knowledge of skin care and protection also improved significantly in both intervention groups.
Conclusion: Visual aids effectively reduced HE prevalence and severity in hospital cleaners. Pictograms are a cost-effective strategy that can be widely implemented, addressing the substantial burden of HE in the cleaning industry across diverse settings.
期刊介绍：
Contact Dermatitis is designed primarily as a journal for clinicians who are interested in various aspects of environmental dermatitis. This includes both allergic and irritant (toxic) types of contact dermatitis, occupational (industrial) dermatitis and consumers" dermatitis from such products as cosmetics and toiletries. The journal aims at promoting and maintaining communication among dermatologists, industrial physicians, allergists and clinical immunologists, as well as chemists and research workers involved in industry and the production of consumer goods. Papers are invited on clinical observations, diagnosis and methods of investigation of patients, therapeutic measures, organisation and legislation relating to the control of occupational and consumers".
