Comilla Sasson MD, MS

Assistant Professor


Comilla Sasson, MD, MS completed her Robert Wood Johnson (RWJ) Clinical Scholar Program Fellowship in 2010 and joined the Department of Emergency Medicine at the University of Colorado School of Medicine in July 2010 as an Assistant Professor. 

Dr. Sasson received her undergraduate and medical degree at the University of Illinois at Chicago.  She completed her residency training in emergency medicine at Emory University in Atlanta, Georgia.  During this time, she served a three-year term as the Emergency Medicine Residents' Association President, representing over 6,000 members internationally. Dr. Sasson earned her Master’s of Science in Health and Health Services Research through the University of Michigan School of Public Health. 

Dr. Sasson’s previous work has focused on creating evidence-based guidelines for prehospital providers.  She has also conducted qualitative research looking at the public policy and operational issues that serve as barriers and facilitators to implementing national evidence-based guidelines for prehospital providers.  In addition, she has completed a meta-analysis of the predictors of survival for cardiac arrest and the temporal trends in survival over the last 30 years.

She is currently working with the Centers for Disease Control and the American Heart Association to utilize Geographic Information Systems (GIS) technology to identify communities that are at highest risk for OHCA, and have low bystander CPR rates, to create targeted CPR educational interventions based at the community level. Her current work utilizes the 30-city CDC-funded surveillance registry, CARES (Cardiac Arrest Registry to Enhance Survival).  She is working directly with communities to create public health programs targeting high-opportunity areas to increase the provision of bystander CPR, and ultimately survival.
