Peter Dayan, MD, MSc

Peter DayanPeter Dayan, M.D., M.Sc., is an Associate Professor of Pediatrics in the Department of Pediatrics at Columbia University Medical Center and is the Associate Division Director of Pediatric Emergency Medicine. In addition to being a practicing pediatric emergency physician, he has been a principal investigator, co-investigator or senior investigator of numerous patient-oriented clinical investigations related to pediatric emergency medicine (PEM). He received his Masters of Science in Biostatistics from the Joseph Mailman School of Public Health.

His main research contributions have come through 17 years of participation and leadership in multicenter research relevant to PEM, particularly studies conducted in the Pediatric Emergency Care Applied Research Network (PECARN) and the Pediatric Emergency Medicine Collaborative Research Committee of the American Academy of Pediatrics. He is now in his 13th year as one of the principal investigators of PECARN and was the prior Steering Committee Chair. PECARN is the first and only federally-funded PEM research network and is regarded internationally as the premier PEM network. His expertise is in the conduct of research aimed to optimize the diagnostic approach for patients with common chief complaints but uncommon outcomes. His research has directly addressed the lack of definitive evidence regarding the risk of and risk factors associated with clinically-important outcomes, such as the need for surgery. Specific research relevant to injury management includes studies to accurately assess the need for neuroimaging in children with minor blunt head trauma.  His recent research has also focused on knowledge translation, including as the lead investigator of an American Recovery and Reinvestment Act funded multicenter trial to test the effectiveness of electronic health record-based clinical decision support to safely decrease CT use for children with minor blunt head trauma.
