Hand eczema is common in healthcare workers, owing to intensive exposure to wet work and skin irritants. Targeted interventions and vocational guidance based on documented exposures and risk factors are needed.
The aims of the study were to investigate the relationship between exposures (domestic and at work) and prevalence and severity of hand eczema.
Self-administered questionnaires were sent to 3181 healthcare workers in Denmark.
Two thousand two hundred and sixty-nine (71%) workers responded to the questionnaire. Frequent hand washing was significantly related to the presence of hand eczema. Having children < 4 years old in the household was also related to the presence of hand eczema. A lower prevalence of hand eczema was found among those using moisturizers at work, and a higher prevalence was found among those using moisturizers at home.
Although healthcare workers are recommended to use disinfectants when the hands are not visibly dirty, hand washing is still significantly related to hand eczema. Frequent hand washing may be a question of behavioural habits, and a focus for future guidance should be on changing hand washing habits. Attention should also be paid to healthcare workers with small children at home. The preventive effect of moisturizers used during working hours should be tested in future follow-up studies.
由于频繁接触湿工作环境和皮肤刺激物，医护人员中常见手部湿疹。需要基于已记录的接触和风险因素进行针对性干预和职业指导。
本研究旨在调查接触（家庭和工作）与手部湿疹的患病率和严重程度之间的关系。
向丹麦的 3181 名医护人员发送了自填式调查问卷。
2269 名（71%）工作人员对问卷做出了回应。频繁洗手与手部湿疹的存在显著相关。家中有<4 岁的孩子也与手部湿疹的存在有关。在工作中使用保湿剂的人群手部湿疹患病率较低，而在家中使用保湿剂的人群手部湿疹患病率较高。
尽管医护人员被建议在手部没有明显污垢时使用消毒剂，但洗手与手部湿疹仍有显著相关性。频繁洗手可能是行为习惯的问题，未来的指导重点应放在改变洗手习惯上。还应关注家中有小孩的医护人员。在未来的随访研究中，应检验工作时使用保湿剂的预防效果。
