Data Submission stage

Syncope - use 'syncope' code, not 'loss of consciousness'. Leg Pain on Walking - add "(Claudication)" to clarify questionnaire. Use 'claudication' SNOMED CT code. BUT --- do we make any effort to verify a cause at this point? If not, a much more general 'pain on walking' 426899007 might be appropriate. Left or Right sided weakness - 50582007, can't distinguish which side. Slurred speech - 289195008 Other - need mechanism to review the free text entries and consider adding to q'aire and also to ontology retrospectively

Diagnosis STEMI - 401303003 (because it's a disorder code, rather than the more specific 'ECG finding' codes) ACS - 394659003 (with additional code - 444931001 - if troponin positive) * note this is relevant only for as long as the test we use is trop I. There's an alternative UK specific code for 'cardiac troponin positive' - 372851000000101 - in TB's spreadsheet, which might be better. There's also a 'cardiac troponin negative code - 372901000000105. Stent thrombosis - 421327009 - not a clear mechanism for differentiating between acute and chronic, and no mention in q'aire of the 'immediate' phase. Perhaps best to just group all thromboses and leave the differentiation for the study Intermittent claudication - 63491006 Arterial occlusion - 2929001 (very general code) Cardiac arrest - 410429000 Done as far as ruptured aortic aneurysm. Start next meeting at ventricular ectopics.
