Validity of the epidemiology of atopic dermatitis is questionable

Today, the prevalence rates of atopic dermatitis are very different worldwide. Epidemiological data are primarily influenced by factors such as the lack of a unified approach to the definition of the disease, study design, disease codes, diagnosis, research methods, etc. In addition, it is important what is the severity of atopic dermatitis and the accuracy of the diagnosis. The use of records in electronic records and prescribed prescriptions also indicate insufficiently accurate identification of such patients. It is necessary to clarify the clinical signs of atopic dermatitis, and the codes of diseases, including those misdiagnosed as atopic dermatitis, which directly affects the epidemiology of this disease.
