Comorbidity identification and referral in atopic dermatitis: a consensus document

Background Atopic dermatitis (AD) is associated with different comorbidities. Objective To develop evidence-based and practical recommendations for comorbidity detection in patients with AD in daily practice. Methods We employed a modified RAND/UCLA methodology, including a systematic literature review (SLR). A group of six experts on AD was established. We conducted a comprehensive search strategy on Medline, Embase, and Cochrane Library up to June 2020. The selection criteria included studies with AD patients with any comorbidity reporting data on comorbidity prevalence, burden, and management. The included studies quality was assessed. The SLR results were discussed in a nominal group meeting, and several recommendations were generated. The recommendation agreement grade was tested on additional experts through a Delphi process. Results The recommendations cover the following issues: (1) Which comorbidities should be investigated at the first and subsequent visits; (2) how and when should comorbidities be investigated (screening); (3) how should patients with specific comorbidities be referred to confirm their diagnosis and initiate management; (4) specific recommendations to ensure an integral care approach for AD patients with any comorbidity. Conclusions These recommendations seek to guide dermatologists, patients, and other stakeholders in regard to early comorbidity identification and AD patient referral to improve decision-making.
