What are the main findings? Response: Headache accounts for about 1-2% of all emergency department visits.  One of the most feared diagnosis within these patients is subarachnoid hemorrhage. While investigations are clearly warranted for patients with a diminished level of consciousness or new focal neurological deficits, approximately 50% of patients with subarachnoid hemorrhage (SAH) have no focal or global neurological findings. Deciding whether to image headache patients with no deficits is difficult, especially since timely diagnosis and treatment results in substantially better outcomes. The desire to never miss a subarachnoid hemorrhage, however, contributes to escalating neuroimaging rates and a dogmatic adherence to lumbar puncture, even if the scan is negative, despite the very high sensitivity of computed tomography. However, a recent population-based study suggested that over 5% of confirmed subarachnoid hemorrhages were missed at initial presentation, especially in smaller hospitals. Therefore, identifying which headache patients require investigations to rule-out SAH is of great importance. We have previously derived (N=1,999) and refined (N=2,131) the Ottawa SAH Rule. In this study, we conducted an multicenter prospective cohort study at six tertiary care hospitals, and found that the Ottawa SAH Rule performed well, with an 100% sensitivity, and specificity of 13.6%.

Minen, MD, MPH Director, Headache Services at NYU Langone Medical Center Assistant professor, Department of Neurology Dr. Mia T. Minen[/caption] Mia Minen, MD, MPH Assistant Professor of Neurology NYU Langone Medical Center MedicalResearch.com Editor’s note: The American Headache Society has issued new guidelines on “The Management of Adults With Acute Migraine in the Emergency Department” (1,2) Dr. Minen, Director of Headache Services at NYU Langone Medical Center, discusses these new guidelines below. MedicalResearch.com: What is the background for these new guidelines? How common/severe is the issue of migraine or headache presentation to the ER? Dr. Minen: These guidelines were needed because previous research shows that there are about 1.2. million visits to the emergency department (ED) each year for migraine, and over 25 different medications are sometimes used for treatment. Many of these medications don’t have evidence-based data to back their usage, and opioids are especially likely to be prescribed in between 60 and 70 percent of these cases, despite their lack of efficacy and risks. The American Headache Society convened an expert panel to review the existing evidence on all the medications used to treat migraines in the ED, and we developed these new treatment guidelines.
