Description

Code list aiming to identify individuals consulting complaining of fever.

Methodology

Identified from intial search terms outside of OpenCodelists: "fever" "pyrexia" "rigor" high temp" "temperature" "hot" febrile"

Clearly irrelevant codes excluded (with review by a second clinician)

Candidate codelist uploaded to OpenCodelists for review of candidate codes.

Specifically excluded hyperpyrexia as likely due to central cause. Included amber and red on NICE traffic light system as they are scoring criteria for feverish children (green excluded as it implies normal).

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.
