Revisions & Caveats

30th October 2025 publication

Please note that figures may differ slightly from previous publications due to a change in methodology for deriving the patient country of  residence. The new methodology assigns country of residence based on the National Statistics Postcode Lookup.

12th March 2024 - Revision of page 3 of Headline Figures

The primary diagnosis figures published on page 3 of the Headline Figures have been revised for 2022/23 due to a data extraction error.  Please note that the new figures may be significantly different from those published previously. This error also affects historic publications and therefore the diagnosis section for Headline Figures prior to 2022/23 have been removed. The affected documents have a suffix of (R).
