Background: The German S2k guideline is the first to include a checklist that captures atopic dermatitis (AD) signs and symptoms as well as the lack of treatment response to identify patients eligible for systemic therapy.
Objectives: Identifying candidates for a start/switch of systemic therapy in adult AD patients in Germany by applying the S2k guideline's checklist.
Methods: In this German multicentre, cross-sectional, non-interventional study (German Clinical Trials Register number: DRKS00023296), adult patients with mild to severe AD were enrolled at dermatological outpatient clinics and offices between April and October 2021. Demographics, clinical characteristics and quality of life were collected using questionnaires during one single visit. Eligibility for a start/switch of systemic AD therapy was evaluated according to the criteria of the German S2k guideline's checklist.
Results: Atopic dermatitis patients (575) were included in the analysis. One hundred and sixty-four patients (28.5%) received systemic (SYS) AD therapy and 411 patients (71.5%) did not (TOP). Of the TOP therapy patients, 38.7% were eligible to start systemic AD therapy, and about half of those (49.1%), were scheduled to start systemic AD therapy. The most frequent reason deciding against a systemic therapy was the patient's wish. Although 29.3% of SYS patients were eligible for a switch according to the criteria of the German S2k guideline's checklist, the majority (81.3%) did not switch AD therapy.
Conclusions: This is the first study on the implementation of the German S2k guideline's checklist in everyday care of AD patients in Germany. More than one-third of the TOP patients were identified as eligible for systemic treatment. By applying the guideline's checklist criteria, another one-third of SYS patients may have benefited from a change of current systemic therapy. The use of the German S2k guideline's checklist in routine care represents an important tool to ensure effective patient care and identify inadequately treated patients.
