Hand Eczema Core Outcome Set (HECOS) Consensus Meeting (Day 1)
Background and aim: Results of studies are often not fully comparable when different outcome domains are measured. HECOS is therefore developing a standardised set of outcome domains (e.g. skin condition, symptoms, quality of life) that should be measured as an agreed minimum set in every therapeutic hand eczema trial. The goal of this 2-day consensus meeting is that all participants finally reach an agreement about the most relevant outcome domains. Everybody with an interest in hand eczema is invited to participate: patients, health professionals, students, researchers, or industry representatives.
