  2. Definition

    This codelist was taken from OpenCodelists, created by OpenSAFELY. We recommend viewing this Phenotype on the OpenCodelist website to view the most recent version.

    A list of high dose inhaled corticosteroid (ICS) preparations at VMP and AMP from the NHS Dictionary of Medicines and Devices.

  3. Methodology

    This codelist is based on the OpenPrescribing.net measure of prescribing of high dose ICS which itself is derived from British Thoracic/SIGN guidance. It includes

    • Inhalers where form-route is pressurizedinhalation.inhalation OR powderinhalation.inhalation

    and

    • BNF codes related to ICS. Full details of BNF codes included can be read in the Jupyter noptebook below.
