Atopic dermatitis is a multifactorial chronic disease that poses a great burden for patients and society. In recent decades the prevalence has increased substantially in many countries, notably in Western societies, and the causes for this increase are not completely understood. There are still many unanswered questions regarding atopic dermatitis with respect to aetiology, pathophysiology, co-morbidity as well as subgrouping and treatment of the disease. Establishment of the Danish Atopy Database (DAD), a cohort with ongoing inclusion of outpatients with atopic dermatitis from a tertiary referral centre, allows the study of these aspects of the disease. Herein we present our methodological considerations in regards to establishment of this cohort.
