Patch testing, the standard method for diagnosing allergic contact dermatitis, has been utilized for over 30 years in China. A 2006 survey found that patch testing was widespread among Chinese dermatologists, but the practice and perceptions were unsatisfactory.
To evaluate the current situation of patch testing practice and perception, we resurveyed Chinese dermatologists.
A cross-sectional survey of Chinese dermatologists was conducted by electronic questionnaires at the 15th National Congress of Dermatology in November 2019.
There were 2199 valid questionnaires collected. About 75% of dermatologists performed patch testing; the majority (59.2%) utilized the baseline (standard) allergen series made in China; others used TRUE Test or the Chemotechnique Diagnostics series, a greater share compared with 2006. Most (92.8%) performed only one single reading, more than 2006. About two-thirds offered patient education after patch testing, but only 27% were executed by trained dermatologists. Dermatologists from regional hospitals more likely performed patch testing and had better perception of patch testing. The majority (88.1%) had received patch testing training, which however did not significantly improve dermatologists' perception.
There was an insignificant improvement in practice and perception of dermatologists compared with 2006. Further education and studies should be conducted. Similar surveys in other countries would be of interest.
斑贴试验是诊断变应性接触性皮炎的标准方法，在中国已经应用了 30 多年。2006 年的一项调查发现，斑贴试验在中国皮肤科医生中广泛应用，但实践和认识并不令人满意。
为了评估斑贴试验实践和认识的现状，我们对中国皮肤科医生进行了再调查。
2019 年 11 月在第 15 届全国皮肤科大会上，通过电子问卷对中国皮肤科医生进行了横断面调查。
共收集到 2199 份有效问卷。约 75%的皮肤科医生进行了斑贴试验；大多数（59.2%）使用中国制作的基础（标准）过敏原系列；与 2006 年相比，更多的人使用 TRUE Test 或 Chemotechnique Diagnostics 系列。大多数（92.8%）只进行一次单一读数，比 2006 年多。大约三分之二的人在斑贴试验后对患者进行了教育，但只有 27%是由受过培训的皮肤科医生进行的。来自地区医院的皮肤科医生更有可能进行斑贴试验，对斑贴试验的认识也更好。大多数（88.1%）接受过斑贴试验培训，但这并没有显著改善皮肤科医生的认识。
与 2006 年相比，皮肤科医生的实践和认识没有明显改善。应开展进一步的教育和研究。其他国家的类似调查将是有趣的。
