  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.

    Codelist for multiple sclerosis including Y codes not mapped previously, Balo disease, Schilder's disease Also includes clinically isolated syndrome and optic neuromyelitis

  3. Methodology

    Codelist designed to identify people who may not have a discrete episode of acute transverse myelitis recorded, due to a diagnosis of MS

    This list includes all codes in https://www.opencodelists.org/codelist/opensafely/multiple-sclerosis/2020-05-12/ It additionally includes: - Y codes (Y1015 Multiple Sclerosis; Y1f23 Multiple sclerosis monitoring invitation) - Balo and Schilder's disease (X005l Balo concentric sclerosis; F211. Schilder's disease or Balo's concentric sclerosis)

    This codelist also includes two related conditions which could be removed for a codelist solely of MS: - Clinically isolated syndrome, on the basis that a person with clinically isolated syndrome who experiences acute transverse myelitis may be diagnosed directly with MS rather than coded as acute transverse myelitis - Optic neuromyelitis, as this condition also includes recurrent episodes of acute transverse myelitis

    The codelist was developed with advice from Arina Tamborska, University of Liverpool
