Pillars of Inquiry

Rigour and Quality: We pursue scholarly rigour and quality in the development and implementation of robust and impactful emergency medicine research and education.
Patient-Centered Care: We hear patient voices and change emergency care to improve patient outcomes and health. 
Priority Community Health Concerns: We focus on the health and health system concerns that are the greatest challenge to our patients, communities, and populations. We recognize emergency medicine as a leader in addressing these concerns.
