Description

Codes indicating an asthma diagnosis

Methodology

This codelist was derived by the following method:

  • Read 2 Codelist provided by LSHTM. This codelist had been used in Nissen et al (see references)
  • Codes from Quality Outcome Framework (QOF) were examined and relevant asthma codes taken
  • Codes from SNOMED were taken by searching for relevant asthma terms

These 3 lists were mapped into CTV3 by TPP to create one list. This list was examined by 2 people and the following logic applied (see github issue for more detail):

  • Codes that related to inhalers (such as inhaler technique) or steroids were excluded as were not felt to be asthma specific
  • Codes for generic respiratory disease were excluded for similar reasons
  • Specific bronchitis was excluded if not included with asthma (such as chronic asthmatic bronchitis)
  • Some occupation causes of respiratory disease such as wood pulp workers disease or byssinosis were excluded as not asthma diagnosis
  • All drug codes were excluded as these are cover in another codelist

Codelists are developed by a broad community of users for individual study purposes, which may or may not meet the needs of other studies. They should not be thought of as universal definitions of a particular condition.

We don't offer any guarantees about what they do or don't identify. Users should carefully check that any codelist meets their needs, and seek clinical input where appropriate.
