New Allergic and Hypersensitivity Conditions Section in the International Classification of Diseases-11

ABSTRACT

Allergy and hypersensitivity, originally perceived as rare and secondary disorders, are one of the fastest growing conditions worldwide, but not adequately tracked in international information systems, such as the International Classification of Diseases (ICD). Having allergic and hypersensitivity conditions classification able to capture conditions in health international information systems in a realistic manner is crucial to the identification of potential problems, and in a wider system, can identify contextually specific service deficiencies and provide the impetus for changes. Since 2013, an international collaboration of Allergy Academies has spent tremendous efforts to have a better and updated classification of allergies in the forthcoming International Classification of Diseases (ICD)-11 version, by providing scientific and technical evidences for the need for changes. The following bilateral discussions with the representatives of the ICD-11 revision, a simplification process was carried out. The new parented "Allergic and hypersensitivity conditions" section has been built under the "Disorders of the Immune System" chapter through the international collaboration of Allergy Academies and upon ICD WHO representatives support. The classification of allergic and hypersensitivity conditions has been updated through the ICD-11 revision and will allow the aggregation of reliable data to perform positive quality-improvements in health care systems worldwide.
