Project

Coding system
CTV3 (Read V3) with TPP extensions
Version
2020-06-23
Codelist ID
opensafely/covid-identification-in-primary-care-case

Description

Codes indicating COVID-19 case (1 of 7 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).
