Current chapter – Purpose of the collection


The NPID audit measures the quality of care received by women with pre-existing diabetes who become pregnant using national standards set out by the National Institute for Clinical Excellence (NICE) guidelines (NG3 and QS109).

The audit is a measurement system to support quality improvement in the care of women with diabetes who are pregnant or planning pregnancy, and seeks to address three key questions:

  • were women adequately prepared for pregnancy?
  • were adverse maternal outcomes minimised?
  • were adverse fetal/infant outcomes minimised?

The audit and its findings will matter to the public, especially to women with diabetes, to health planners and policy makers, as well as acute trusts, Clinical Commissioning Groups (CCGS), clinical networks, primary care teams, and specialist diabetes and maternity services.


Who should take part

As one of the audits within the National Clinical Audit and Patient Outcomes Programme (NCAPOP), participation in the National Pregnancy in Diabetes audit is a requirement in the NHS standard contract for acute hospitals with obstetric services and will form part of your Trust’s Quality Accounts. All maternity units with a joint diabetes and maternity service in England and Wales are eligible to participate. Registration is at hospital level not Trust level.

The audit collects data on women with diabetes and their pregnancy; it does not collect information about women with gestational diabetes.


Benefits of participating

By taking part in the audit, services will benefit from:

  • an easy to use, validated approach to the collection and analysis of quality monitoring information covering all the key interventions and preventable adverse outcomes of pre-gestational diabetic pregnancy
  • regional and service level benchmarked reports (in dashboard form). These can be used for service assurance, prioritisation of areas for improvement and measurement of the effectiveness of improvement initiatives
  • National Pregnancy in Diabetes audit short reports
  • access to download your hospital’s completed audit records to use for local analysis and benchmarking against national and regional published data. (Please note that this includes all data items submitted via the secure web entry system but does not include any information from linked data)
