Description
DEFINITION: A history of venous thromboembolic disease
Variables: (1) a binary variable denoting the presence of one of the codes at any point in the patient record. (2) the earliest date of such a code.
Methodology
Process (1) Read 2 code list from Helen Strongman and Angel Wong combined here: We did not include codes for suspected/possible DVT/PE; nor PEs specified as air embolism or amniotic fluid embolism as would not indicate at ongoing risk of a venous thrombosis/clot. (2) SNOMED searched for DVT and PE
didn't include air embolisms, fat embolisms, or amniotic fluid embolisms or suspected PE assumed unspecified PEs were blood clots. (3) mapped to CTV3 and reviewed by Helen McDonald and Amir Mehrkar, principles discussed with Laurie Tomlinson as above. To reflect the conversation, HM updated the spreadsheet with a final recommendation CTV3venousthromboembolismcombiningcomments.xlsx FLEXIBILITY NEEDED BETWEEN STUDIES: This list
doesn't include fat pulmonary embolism, air pulmonary embolism or amniotic fluid pulmonary embolism (though assumes unspecified PEs are thromboembolic) includes codes for any history of DVT or PE - studies of incident DVT/PE may wish to exclude these. includes codes for PE/DVT in pregnancy, which may not be relevant for all studies includes codes for cerebral venous thrombosis (which may be caused by cerebral inflammation eg. meningitis and is only very rarely associated with PE) and portal thrombosis (which may be caused by liver pathology and should not be able to result in PE) and mesenteric thrombosis, not all of which may be relevant for other study questions. EFFECTS ON COHORT SELECTION: None
POTENTIAL BIASES: This variable includes a history of any venous thrombosis. Some DVTs/PEs will have occurred in the context of a temporary condition (e.g. pregnancy, meningitis, immobility), and some individuals identified by this codelist will be at higher risk of future DVT/PE than others

Codelists are developed by a broad community of users for individual study purposes, which may or may not meet the needs of other studies. They should not be thought of as universal definitions of a particular condition.
We don't offer any guarantees about what they do or don't identify. Users should carefully check that any codelist meets their needs, and seek clinical input where appropriate.
