  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.

    This lists contains CTV3 codes used to identify people who may have had diabetes ketoacidosis (DKA). It has been generated based on a DKA snomed list using internal mappings. The SNOMED codelistlist was conceived to identify DKA in a specific group of patients in a specific time period, therefore we have been permissive in including unspecific codes which may not be suitable for all studies.

  3. Methodology

    Using the OpenCodelists builder we used the following search terms to build the SNOMED list

    • dka
    • ketoacidosis
    • acidosis

    Mapped codes can be viewed in GitHub discussion below.
