User Requirements
The ISARIC COVID-19 case report form collects data on patients medical history. A detailed completion guide collects data on patients medical history.
A planned ISARIC validation study requires a series of SNOMED CT codelists to replicate as closely as possible the details given in the ISARIC case report form.
This codelist is designed to extract patients with clinically identified deficiency in intake, either of total energy or of specific nutrients that led to a dietetic intervention or referral prior to the onset of COVID‐19 symptoms. It should not include people who needed supplementary nutrition solely due to reduced intake during their current illness episode.
