The American Academy of Allergy, Asthma & Immunology/American College of Allergy, Asthma and Immunology Joint Task Force Atopic Dermatitis Guideline Panel recently released updated AD guidelines. This guideline focuses on addressing clinical questions using trustworthy guideline development standards, including mitigating the potential influence of financial and nonfinancial conflicts of interest, and Grading of Recommendations Assessment, Development, and Evaluation methodology. A multidisciplinary panel used systematic reviews and meta-analyses to inform specific recommendations addressing optimal use of topical treatments, dilute bleach bath, dietary avoidance/elimination, allergen immunotherapy, and systemic treatments. The comprehensive recommendations, emphasizing the third principle of evidence-based medicine-that evidence alone is never enough, and that patient values and preferences must be carefully considered when determining optimal treatments for patients and populations-provide a framework to support clinicians in selecting an optimal treatment plan for each patient.
