Emergency department management of the acute headache

Headache is a common complaint of patients seeking care at an emergency department (ED). A survey of more than 16,755 walk-in patients at an ED showed that 323 (1.9%) had a chief complaint of migraine (1). Almost one sixth of these patients had used the ED more than once. In fact, migraineurs used the ED and other health care providers 2 to 5 times more than nonmigraineurs (2). Fortunately, headaches associated with significant morbidity and mortality occur infrequently (3). The ED physician must be able to address the patient's need for pain management and establish the correct diagnosis for the headache while also ruling out any possibility of organic disease or life-threatening illness. Potential problems include ensuring appropriate follow-up and avoidance of narcotic habituation.
