Codes that indicate incident or history of antiphospholipid syndrome
These codes were mapped first in SNOMED using the opencodelist builder. The search terms used were:
Though a broad search term, "lupus" was included to capture codes such as Lupus anticoagulant positive". Lupus anticoagulant is synonymous with the detection of antiphospholipid antibodies which is seen in antiphospholipid syndrome. 12 codes were identified in SNOMED.
The codes were discussed by 2 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 8 codes. One extra TPP CTV3 code was identified from Tree which resulted in 9 codes in total.
This definition has been computed by taking the manually created full codelist and converting it to a list of rules that define the codelist.
