Abstract
ABSTRACT: Atopic dermatitis is a chronic inflammatory skin condition that affects approximately 18 million people in the United States. Assessing the extent and severity of atopic dermatitis is critical for determining baseline disease burden and treatment effectiveness for both investigators and clinicians. Considerable efforts over the past several decades have been made in developing a highly validated instrument called the Eczema Area and Severity Index (EASI). Although several guides exist for the EASI, questions continue to arise regarding its use and interpretation. This review was developed to serve as the definitive guide for the EASI and to address commonly asked questions.
