Primary headache disorder in the emergency department: perspective from a general neurology outpatient clinic

Over a six month period, 22% of patients with headache seen in general neurology outpatient clinics reported prior attendance at an emergency department because of their headache; 9% of the headache cohort had been admitted to hospital. All had primary headache disorders according to International Headache Society diagnostic criteria. Improved primary care services for headache patients are required to reduce the burden of primary headache disorders seen in emergency departments.
