The worksheets include data for all ICBs and GP practices in England within the May 2025 extraction of NDA data (April 2024 to March 2025 data). These data undergo further validation processes at the end of each audit year when data from specialist services are added in, at which point the data are considered to comprise the full annual dataset to be used in the annual NDA publications. Data for Local Health Boards (LHBs) in Wales and specialist diabetes services in England are not included in the quarterly publications. Their 2024-25 data (for the full audit period April 2024 to March 2025) will be extracted as part of the final NDA 2024-25 collection and reported in the NDA 2024-25 full audit period data release, scheduled for late 2025. Disclosure control has been applied to mitigate the risk of patient identification. Zeros are reported, and all numbers are rounded to the nearest 5, unless the number is 1 to 7, in which case it is rounded to ‘5’. This allows for more granular data to be made available, and also for data for all GP practices to be made available. Percentages where the denominator is less than or equal to 20 are not reliable and have therefore not been calculated in this release.

The worksheets include data for all integrated care boards (ICBs) and GP practices in England within the February 2024 extraction of the National Diabetes Audit (NDA) data (January to December 2023 data).
