About

Description

Codelist to identify new diagnoses of heart failure in secondary care (admitted patient care data).

JJL - I tried a few search terms to no benefit. I have included acute on chronic, as it is the diagnostic event, not new pathology that we are trying to identify. I excluded foetal/neonatal as this study is of adults.

JJL: Updated 19/12/25 to remove HCM

Methodology

Codelist based on a combination of those used in Hayhoe et al and Taylor et al.

J81 (Pulmonary oedema) excluded.

References

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.
