National Diabetes Audit

The National Diabetes Audit (NDA) is the largest annual clinical audit in the world, integrating data from both primary and secondary care sources, making it the most comprehensive audit of its kind. The audit is now closed for submissions for the 2013-14 and the 2014-15 collections.

The results of the 2013-14 and 2014-15 collections will be published together in the next annual report; further information including dates of publication will be available from this website shortly.

What does it measure?

The National Diabetes Audit is a major national clinical audit, which measures the effectiveness of diabetes healthcare against NICE Clinical Guidelines and NICE Quality Standards, in England and Wales. The NDA collects and analyses data for use by a range of stakeholders to drive changes and improvements in the quality of services and health outcomes for people with diabetes.

The National Diabetes Audit (NDA) answers four key questions based on the diabetes National Service Framework (NSF):

  • Is everyone with diabetes diagnosed and recorded on a practice diabetes register?
  • What percentage of people registered with diabetes received the nine NICE key processes of diabetes care?
  • What percentage of people registered with diabetes achieved NICE defined treatment targets for glucose control, blood pressure and blood cholesterol?
  • For people with registered diabetes what are the rates of acute and long term complications (disease outcomes)?

Aims and Objectives

The NDA aims to improve the quality of patient care by enabling NHS organisations to:

  • compare their outcomes of care with similar NHS organisations
  • identify and share best practice
  • identify gaps or shortfalls in commissioning services
  • assess local practice against NSF for diabetes and NICE guidelines and drive service improvement
  • provide a more comprehensive picture of diabetes care and outcomes in England and Wales

Through participation in the audit, local services are able to benchmark their performance and identify where they are performing well, and improve the quality of treatment and care they provide. On a national level, wide participation in the audit also provides an overview of the quality of care being provided in England and Wales.

Who manages the audit?

The National Diabetes Audit (NDA) is commissioned by the Healthcare Quality Improvement Partnership (HQIP) as part of the National Clinical Audit Programme (NCA) and delivered by the Health and Social Care Information Centre in partnership with Diabetes UK and the National Cardiovascular Intelligence Network (part of Public Health England). The NDA receives expert input from clinicians and people with diabetes across England and Wales
