Most studies investigating the prevalence of hand eczema (HE) in professional cleaners use self-reported questionnaire-based data. However, no validation studies of self-reporting of HE among professional cleaners have previously been conducted.
To investigate (1) the point prevalence of self-reported HE, (2) the point prevalence of HE estimated by physical examination of the hands and (3) the sensitivity and specificity of self-reporting of HE compared with the diagnosis based on physical examination among professional cleaners.
Professional cleaners at three different hospitals in Region Zealand were invited to fill out a questionnaire. The point prevalence of self-reported HE was estimated based on questions from the Nordic Occupational Skin Questionnaire. After completing the questionnaire, each cleaner underwent a physical examination of the hands by a dermatologist on the same day.
In total, 234 cleaners were invited to participate in the study, and 224 (response rate = 96.0%) agreed to take part. Based on the self-reported questionnaires, 5.3% (n = 12) of the cleaners had current HE. Based on an examination by a physician, 19.2% (n = 43) of the cleaners had current HE. The sensitivity of self-reported HE was found to be 28.0%, while the specificity was found to be 100.0%. The positive predictive value was found to be 100.0%, while the negative predictive value was 85.0%.
The true point prevalence of HE among professional cleaners is underestimated when based on self-reporting.
大多数研究调查职业清洁人员手部湿疹（HE）的患病率时，都使用基于自我报告的问卷调查数据。然而，以前从未进行过职业清洁人员自我报告 HE 的验证研究。
调查（1）自我报告 HE 的时点患病率，（2）手部体格检查估计的 HE 时点患病率，以及（3）与基于体格检查的诊断相比，职业清洁人员自我报告 HE 的敏感性和特异性。
邀请三个不同的泽兰地区医院的职业清洁人员填写问卷。自我报告 HE 的时点患病率是基于北欧职业性皮肤调查问卷的问题来估计的。完成问卷后，每位清洁人员在同一天由皮肤科医生进行手部体格检查。
共邀请了 234 名清洁人员参加研究，224 名（应答率=96.0%）同意参加。根据自我报告问卷，5.3%（n=12）的清洁人员患有现患 HE。根据医生的检查，19.2%（n=43）的清洁人员患有现患 HE。自我报告 HE 的敏感性为 28.0%，特异性为 100.0%。阳性预测值为 100.0%，阴性预测值为 85.0%。
基于自我报告，职业清洁人员 HE 的真实时点患病率被低估。
