Description

A SNOMED CT codelist for patients receiving monitoring of red blood cell (RBC) tests with a numerical value

Methodology

We identified the full set of red blood cell level codes (see RBC codelist), and excluded any codes which did not have at least 10 thousand codes in EMIS and SystmOne recorded in 2020, where a reasonable proportion had numerical values attached.

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.
