What is the eIGA for atopic dermatitis?

The Investigator Global Assessment (IGA) is a 6-point scoring system used to assess the severity of atopic dermatitis. The terms physician or investigator global assessment (IGA) may be used interchangeably. IGA is assessed via the intensity of the erythema and papulation/infiltration and gives a general impression of severity or improvement of AD over time. The IGA was originally developed to assess the disease severity within clinical trials and is one of the standard parameters collected to assess treatment success. In recent time, IGA is more commonly used in clinical practice to guide treatment decisions for physicians and document the impact of the clinical treatment over time.

How to use the eIGA for atopic dermatitis

The IGA should only be used by trained physicians. IGA for AD is assessed by the intensity of the erythema and papulation/infiltration and ranges from clear (0), almost clear (1), mild (2), moderate (3), to severe (4) and very severe disease (6). Each severity grade is distinctly defined by a relevant morphologic description to ensure comparability of IGA scores between health care providers and over time.
