National Diabetes Inpatient Audit

The National Diabetes Inpatient Audit (NaDIA) is a snapshot audit of diabetes inpatient care in England and Wales.

This audit is part of the National Diabetes Audit Programme.


Due to the COVID-19 pandemic, NHS England, the audit commissioners, and other stakeholders, have instructed the audit to cease plans for any future collections via paper questionnaires. Because of this there will not be a NaDIA bedside audit from 2020 onwards. The NaDIA-Harms collection continues as normal.

Latest Report

The 2019 NaDIA annual report was published on Friday 13 November 2020.

Due to COVID-19 only a Hospital Characteristics Report was carried out in 2020. This was partially incorporated into the 2020 NaDIA-Harms report and published in July 2021.

What is the National Diabetes Inpatient Audit?

The National Diabetes Inpatient Audit (NaDIA) is an annual snapshot audit of diabetes inpatient care in England and Wales and is open to participation from hospitals with medical and surgical units. NaDIA allows hospitals to benchmark hospital diabetes care and to prioritise improvements in service provision that will make a real difference to patients' experiences and outcomes.

We encourage as many hospitals as possible to take part in the audit, which helps to drive improvements in the care of in-patients with diabetes in England and Wales.

What does it measure?

The audit sets out to measure the quality of diabetes care provided to people with diabetes while they are admitted to hospital, by answering the following questions:

• Did diabetes management minimise the risk of avoidable complications?

• Did harm result from the inpatient stay?

• Was patient experience of the inpatient stay favourable?

• Has the quality of care and patient feedback changed since the previous audit years?

Who manages the audit?

The National Diabetes Inpatient Audit (NaDIA) is commissioned by the Healthcare Quality Improvement Partnership (HQIP) as part of the National Clinical Audit and Patient Outcomes Programme (NCAPOP), and delivered by NHS Digital, working with Diabetes UK.

How to participate

The audit is open to participation from England and Wales hospitals only and takes place every year.

The NaDIA Team contacts each eligible hospital prior to the audit to provide hospitals with further information on the audit and to gather up to date hospital participation details. Once registration details are confirmed, participating units receive audit packs containing:

· Bedside Audit forms

· Patient Experience questionnaires 

· Supporting information and guidance

Each participating hospital will also be required to complete a Hospital Characteristics form electronically to provide information on resources and the staffing structure to assist in the provision of the audit findings.

If you wish to register your hospital or to check if your hospital has already registered, please contact the NaDIA team on
