National Paediatric Diabetes Audit (NPDA) - data submission

The following information is about the NPDA core audit.

Which centres are eligible to participate in the NPDA?

All paediatric diabetes units in England, Wales and Jersey. 

However, children and young people are not eligible for the NPDA if they:

• are receiving care from non-NHS organisations (England, Wales and Jersey)
• have a diagnosis of gestational diabetes.

The NPDA is exempted from the National Data Opt Out. Unless a patient specifically requests to opt out of the audit, you should enter their data.

2025/26 Dataset - information

We ask that PDUs in England, Wales and Jersey submit data from all patient visits. You should include data relating to all children and young people with all types of diabetes under the care of a paediatrician within your PDU.

PDUs can submit data throughout the audit year. We encourage you to submit your data on a quarterly basis.

After you submit, you will see summary results in the patient report (was the data completeness report).

You can download the dataset (including notes) for both audit years in the Downloads section below. You can download the CSV submission template for both audit years here. 

2026/27 Dataset - update

The NPDA Core Dataset has been updated for the 2026/27 audit year (from 1 April 2026) to ensure it remains aligned with current practice and guidance, and to further improve data quality. The new dataset introduces additional data items, updates to existing fields, and wording changes to improve clarity.

Changes include:

• New questions around neurodiversity, immunotherapy, access to mental health professionals, and tests at admission
• Updated treatment questions to separate out insulin treatment, blood glucose lowering medication, and lifestyle and dietary modification
• Updated response items on CGM, smoking status, and reason for admission
• Wording changes to improve clarity

The NPDA platform will be updated with these new fields by 1 April 2026. You can download the updated dataset and CSV upload template from this page.

NPDA Webinar: Demonstrating the New Platform

This webinar, held on 11 September 2025, demonstrates the new NPDA data submission platform. It includes an overview of the benefits of the system, a step-by-step walkthrough showing how to enter data, how to add colleagues to the system, and how to correct errors, as well as a Q&A session where the project team and developers respond to questions from attendees.

NHS England’s Hybrid closed loop (HCL) technologies

For English PDUs, data from the NPDA is shared with NHS England in support of the HCL implementation strategy and reimbursement funding. To support reimbursement, we are asking PDUs to submit a visit when a patient starts a new treatment, even if they haven’t had a clinic visit. This should include the visit date (date item 13) and treatment questions (data items 20, 21 and 22). This is particularly important for new HCL users.

This will be sent to NHS England to support reimbursement but dropped from NPDA analysis if it doesn’t have an associated HbA1c. For Twinkle users, Hicom are making this change to the NPDA extract. When a patient starts a new treatment enter a visit into the Twinkle system with the new treatment recorded and it will be included in your extract.

GP practice codes

These are updated quarterly by NHS Digital. The most up to date version can be found on its website: GP and GP practice related data.
