  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.

    Codes that indicate an episode of transverse myelitis

  3. Methodology

    These codes were mapped first in snomed using the opencodelist builder. The search terms used were:

    • transverse myelitis
    • myelitis

    We checked with the CPRD code finder for any other terms for inspiration too and found none.

    The codes were discussed by 3 practicing doctors. A summary of this discussion is available on the github issue below.

    These codes were mapped to CTV3 and rechecked. One higher level code that is now extinct that grouped transverse myelitis in with encephalitis and encephalomyelitis was excluded after discussion with the 3 clinicians.

    The final codelist was signed off by the 3 clinicians indicated below.
