Description

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

Methodology

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).
