About

Description

Codes indicating COVID-19 case (SNOMED mapping of 1 of 13 possible types of CTV3 codes that contain information related to COVID-19)

Methodology

SNOMED mapping of the codelist created by:

Search of TPP CTV3 codes for terms relating to coronavirus, with additional (manual) check for any missing terms against the SNOMED list of COVID-19 related codes.

Classification as "case" was then performed following review of terms by six OpenSAFELY team members (including epidemiologists, clinicians, statisticians and infectious disease modellers).

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.

Codes not in the full codelist are in faint grey.
