Summary
The worksheets include data for all ICBs and GP practices in England within the February 2026 extraction of NDA data (April to December 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 2025-26 data (for the full audit period April 2025 to March 2026) will be extracted as part of the final NDA 2025-26 collection and reported in the NDA 2025-26 full audit period data release, scheduled for late 2026.
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.
We are aware that some pathology laboratories have been affected by HbA1c analyser issues in 2024/25. These may have resulted in higher HbA1c results than would otherwise have been expected.
NHS England are currently reviewing the routine production of NDA State of the Nation reports. Please note that data will still be released via dashboards and standalone data files whilst this review is being conducted.
To help inform this review we would be grateful if users can provide feedback on their use of the State of the Nation reports using the feedback survey available in the ‘Related links’ section of this page.
Highlights
