Codes that indicate incident or history of transient ischaemic attack. This codelist include definite and probable transient ischaemic attack. Future studies which require codes denoting definite transient ischaemic attack need to derive another codelist.
These codes were mapped first in SNOMED using the opencodelist builder. The search terms used were:
Codes only indicating the assessment scale (CHAD2S2-VASc score itself), high risk of TIA, suspected case and family history of TIA were excluded. 36 codes were identified in SNOMED.
The codes were discussed by 1 practicing clinicians and 1 epidemiologist. A summary of the discussion is available on the github issue below.
These codes were mapped to CTV3 which resulted in 24 codes.
This definition has been computed by taking the manually created full codelist and converting it to a list of rules that define the codelist.
