Dr. Mercedes Pilkington is an Assistant Professor at the University of Toronto and a Staff Surgeon in the Division of Paediatric General and Thoracic Surgery at The Hospital for Sick Children (SickKids). She completed her General Surgery training at Queen’s University and her Paediatric General and Thoracic Surgery fellowship at the University of Calgary. She completed additional research fellowships in paediatric surgical innovation at the University of Michigan and a Safe Surgery/Safe Systems fellowship jointly with Ariadne Labs, Brigham Women’s Hospital, Harvard T.H. Chan School of Public Health, and EQuIS at the University of Calgary. She has a Master’s in Global Surgical Care from the University of British Columbia. Her current clinical and research interests include neonatal surgery, Enhanced Recovery After Surgery, and strengthening surgical systems to promote safer surgery in a variety of resource settings.


Pilkington uses mixed methods to understand how to use evidence-based care to standardize and improve paediatric surgical outcomes. This work involves creating Enhanced Recovery After Surgery guidelines for the neonatal population as well as studying the implementation of such protocols in variable resource settings, adaptation of surgical safety tools including the WHO Surgical Safety Checklist, and the creation of new safety tools to improve surgical care delivery.
