Patient Management Recommendations

Risk-stratification strategies

Use the Ottawa Subarachnoid Hemorrhage Rule ≥40 years, complaint of neck pain or stiffness, witnessed loss of consciousness, onset with exertion, thunderclap headache, and limited neck flexion on examination) as a decision rule that has high sensitivity to rule out SAH, but low specificity to rule in SAH, for patients presenting to the ED with a normal neurologic examination result and peak headache severity within 1 hour of onset of pain symptoms.

Preferentially use nonopioid medications in the treatment of acute primary headaches in ED patients. (A)

Imaging

Use a normal noncontrast head CT* performed within 6 hours of symptom onset in an ED headache patient with a normal neurologic examination, to rule out nontraumatic SAH. (B)
* Minimum third-generation scanner

Perform LP or CTA to safely rule out SAH in the adult ED patient who is still considered to be at risk for SAH after a negative noncontrast head CT result. (C)
