Patch test informed consent form: position statement by European Academy of Dermatology and Venereology Task Force on Contact Dermatitis. J Eur Acad Dermatol Venereol. 2021 Oct;35(10):1957-62. DOI: 10.1111/jdv.174830926-9959http://hdl.handle.net/10230/52807Background: To our knowledge, an international consensus is lacking regarding the development of an adequate informed consent form for a patch test (PT) and the information that should be included in such document. Objectives: The aim of the study was to reach a consensus on the specific points that need to be addressed in a PT consent form. Methods: A Delphi survey, comprising 2 rounds and 1 final discussion, was used to gather and analyse data, which was conducted over the Internet. Each statement that reached a consensus with the respondents (9 expert dermatologists from Europe) was defined as a median consensus score (MED) of ≥7 and agreement among panelists as an interquartile range (IQR) of ≤3. All study participants were members of the EADV task force on contact dermatitis. Results: The expert panel addressed several topics that should be included in an informed consent form for a PT: introduction, preparation for PT, testing procedure, allowed activities, adverse events and additional authorizations. Conclusions: Our results assess recommendations regarding points to be contained in an informed consent form for a PR. Future actions towards standardization and harmonization of this specific consent form are needed.application/pdfengThis is the peer reviewed version of the following article: Balato A, Scala E, Ayala F, Bauer A, Crépy MN, Gonçalo M, Duus Johansen J, John SM, Rustemeyer T, Wagner N, Wilkinson M, Giménez-Arnau A.
