Scientist, CHEO Research Institute

Dr. Waleed Alqurashi completed his pediatric residency training at the Montreal Children’s Hospital and McGill University and his fellowship training in pediatric emergency medicine at the Children’s Hospital of Eastern Ontario (CHEO) and the University of Ottawa. He then completed a Master’s degree in Clinical Epidemiology at the University of Ottawa while doing a research fellowship at The Ottawa Hospital Research Institute. He also completed the Society for Academic Emergency Medicine (SAEM) research fellowship. He joined the Division of Emergency Medicine at CHEO and the Department of Emergency Medicine at the University of Ottawa in 2013. Since then, he has been a clinical investigator at the CHEO Research Institute. He secured research funding and published scholarly projects related to allergic reactions and anaphylaxis, with a particular focus on biphasic anaphylaxis, anaphylaxis epidemiology, and anaphylaxis related patient education materials.

He is a member of the CHEO Antibiotic Stewardship Program and leading a penicillin de-labelling project in the Emergency Department. Dr. Alqurashi is the Content Advisor for anaphylaxis at the Translating Emergency Knowledge for Kids (TREKK), a national centre of excellence aimed at bringing evidence-based pediatric emergency care to general emergency departments across Canada. He is also a member of the Editorial Board of the TREKK network.

  1. Epinephrine MDI for Pediatric Croup. Academic Emergency Medicine


    The QA network formed a committee of Canadian experts in pediatric emergency medicine, pharmacology, critical care, and aerosol delivery who, through consensus, approved an assessment and dosing algorithm that incorporated relevant evidence identified through literature review. Using a standardized bedside data collection form, the algorithm recommended administering five puffs (125 μg/puff) via MDI with a valved holding chamber (VHC), with assessment recommended 10 min later for clinical improvement using the Westley Croup Score (WCS)4 and for adverse effects by documenting heart rate (HR), cardiac rhythm, and presence of tremor or agitation.
