NAHD is the major national healthcare quality improvement programme for headache disorders.  We measure how well care for headache disorders is being delivered across UK.  We aim to provide timely information to clinicians, commissioners, patients and the public so it can be used to improve the quality of care that is provided to patients. 

NAHD currently runs the National Audit of Migraine. The National Audit of Migraine measures the processes of care provided to adult migraine patients. All our audits measure migraine care against evidence-based standards.​​

NADH is hosted by King's College London.
