Information for Caldicott Guardians of NHS Organisations - National Diabetes Audit

Information necessary to approve the participation of your trust in the National Diabetes Audit (NDA).


The NDA Core answers five key questions:

  1. Is everyone with diabetes diagnosed and recorded on a practice diabetes register?
  2. What percentage of people registered with diabetes received the nine National Institute of Health and Care Excellence (NICE) key processes of diabetes care?
  3. What percentage of people registered with diabetes achieved NICE defined treatment targets for glucose control, blood pressure and blood cholesterol?
  4. What percentage of people registered with diabetes are offered and attend a structured education course?
  5. For people with registered diabetes, what are the rates of acute and long-term complications (disease outcomes)?

Specialist services have lead responsibility for the core management of Type 1 diabetes, including transition from paediatrics and diabetes technology, Through participation in the audit, services are able to benchmark their performance, identify where they are performing well, and improve the quality of treatment and care they provide. Our reports can be found on the National Diabetes Audit collection page.


All trusts with specialist diabetes services in England are expected to participate in this NCAPOP audit; participation forms part of the reporting that providers should include in their annual Quality Accounts.

Access to audits, registries and collections

To participate in the National Diabetes Audit, Caldicott Guardians must sign the Clinical Audit Platform (CAP) User form electronically for the user(s) requested. Instructions on the form, then signpost onward transmission to NHS Digital. NHS Digital will then verify identity by checking the source email address and cross referencing with the Caldicott Guardian register.

Once the registration form has been approved, the user(s) will receive a notification email and access to CAP will be enabled for the specified audit only.

CAP is a secure platform that is used to collect secondary use data for many clinical audits, registries and collections.  NHS Digital has strict patient data safety systems. All data is held securely on encrypted servers. Access to patient records is restricted to crucial personnel who have received Caldicott Guardian approval. Once the data is received it is pseudonymised. This means that:

  • dates of birth are converted to age, or year of birth
  • postcodes are converted to lower layer super output areas (LSOA)
  • NHS numbers are converted to a unique ID for that person
