The National Audit of Headache Disorder (NAHD) is a clinical audit to evaluate the quality of care provided to adult migraine patients across UK. A key aspect of the audit is to describe patterns of care across UK. The NHAD started in October 2024. The first programme of the NAHD is the National Migraine Audit and Registry.

Clinical audit is a tool used by health care professionals to monitor and improve patient care by comparing how patients are treated and their outcomes against explicit standards or guidelines. In a clinical audit, information on the care received by patients is collected and analysed to see if clinicians and hospitals are following national clinical standards, such as those published by the National Institute for Health and Care Excellence (NICE). These audits usually also produce information for hospitals to compare their outcomes of care with other hospitals.

The NAHD is a national audit run by the steering committee of the NADH. The NAHD, including the National Migraine Audit are hosted by King’s College London. Day to day running of the NAHD is managed by the Headache Research Team at the King’s College London.

We want to support the improvement of primary and secondary care for headache patients. Research shows that there are differences in the care given to patients across the UK. The NAHD aimes to find out what these differences are and to understand why these differences are happening. We plan to share our findings with hospitals and health care policy makers across UK . In particular, we want to inform them about the areas of headache and migraine care that they were doing well in and where they could improve.

Currently we run the National Audit for Migraine. All migraine patients who received a migraine diagnosis at an NHS clinic in England, Wales, Scotland and North Ireland can participated in the National Migraine Audit. To participate in the Audit please download the Audit's migraine app, and agree to the Terms and Conditions and Consent form.

The National Audit for Migraine and Registry collects data directly from patients who consent to participate and share their data through the Migraine Audit e-Diary app and the history tool in the website. Any data provided will be processed in accordance with UK data protection law including the UK General Data Protection Regulation (UK GDPR) and the Data Protection Act 2018.

We also collect aggregated data from the Clinical Practice Research Datalink | CPRD, which provides anonymised healthcare data and research services that are used to improve health care delivery and inform clinical guidance.

Findings from the National Audit for Migraine will be published on this website.

More information on how King’s College London manages data can be found in our Privacy Policy.

The national data opt-out allows patients to opt-out of their information being used for purposes other than their immediate clinical care (such as for audit and research purposes). Please email us at migraineaudit@kcl.ac.uk with any enquiries.

All NHS organisations are required to be compliant with the national data opt-out policy.

We used data collected on patients who were diagnosed with migraine or other headache disorders from 30th of September 2024 onwards and received care in NHS hospitals across the UK.

The aim of the audit is to improve the care received by patients with migraine, by making recommendations to primary and secondary services based on our findings. For example, the National Audit for migraine can make recommendations on:

• How and when migraine patients are diagnosed and how their care is managed

• The type of treatments the patients receive

• The use of brain imaging for headache disorders

We work closely with patient representatives and patient charities on many aspects throughout the project, from deciding what information to collect, to how the results are reported.

The following websites provide general information and support about migraine and headaches:

• Migraine Trust

• Association of Migraine Disorders

• NHS website

• OUCH UK

• Trigeminal Neuralgia Association

Participation to the Audit is free, including the use of the audit tools such as the Migraine Audit e-diary app.
