Consensus on a Patient-Centered Definition of Atopic Dermatitis Flare.

Importance: Flare is a term commonly used in atopic dermatitis (AD) care settings and clinical research, but little consensus exists on what it means. Meanwhile, flare management is an important unmet research and treatment need. Understanding how various therapies might comparatively improve AD flares as a measure of treatment effectiveness may facilitate shared decision-making and enable assessment of effectiveness within and outside clinical settings.

Towards a patient-centred definition for atopic dermatitis flare: a qualitative study of adults with atopic dermatitis.

Background: The term 'flare' is used across multiple diseases, including atopic dermatitis (AD), to describe increased disease activity. While several definitions of an AD flare have been proposed, no single definition of AD flare is widely accepted and it is unclear what the term 'AD flare' means from the patient perspective.

Objectives: To understand AD flares from the adult patient perspective and to explore how adults with AD define an AD flare.
