COVID identification in primary care - unrelated to case status



Coding system
CTV3 (Read V3) with TPP extensions
Project
OpenSAFELY
Codelist ID

Version

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