Ottawa SAH Rule

New clinical decision rule could reduce misdiagnosis of deadly brain bleeding

"Researchers from Ottawa, Canada have developed a simple clinical decision rule that may help emergency doctors identify which patients with headache have a dangerous subarachnoid hemorrhage or SAH (bleeding in a certain area of the brain).

The study is published in the September 25 issue of the Journal of the American Medical Association (JAMA). It is led by Dr. Jeffrey Perry, senior scientist at the Ottawa Hospital Research Institute (OHRI), emergency physician at The Ottawa Hospital (TOH) and associate professor at the University of Ottawa (uOttawa)."
