Patient Age Group


I am a pediatric intensivist, specializing in the care of critically ill and injured infants, children and adolescents.  After completing training in General Pediatrics and Pediatric Critical Care at MGH,  I joined the faculty at MGH and HMS in 2006, where I provide clinical care, supervise trainees and conduct research in innovative technologies to enhance our medical knowledge, quality of patient care and education of trainees.

 In my role as Program Director for the Pediatric Critical Care Medicine Fellowship since 2010, I have expanded our fellowship training to include an ethics curriculum, a leadership curriculum, in situ, simulation-based team training, and global health opportunities for our trainees.  As the Simulation Officer for the Department of Pediatrics, I have led workshops for Pediatric faculty interested in learning how to facilitate and debrief simulated patient encounters.  Through the use of telemedicine, I have recently developed a telesimulation program enabling remote facilitation of simulation-based team training for providers at outlying community hospitals so they may practice as teams in their own work environment and receive expert feedback from an intensivist trained in debriefing.  In 2017, I became Chief of the Division of Pediatric Critical Care at MGH.  In this role I have sought to provide faculty development opportunities, including coaching workshops and hands-on training in bedside ultrasound.  Through the creation of a division-level clinical research group, I hope to foster the growth of clinical research initiatives in our division, including greater involvement in multi-site prospective studies to further our understanding of pediatric critical illness and to improve treatment modalities.

Research & Publications

Research Summary

Dr. Yager's research interests center on the use of innovative technologies to enhance the care  of critically ill and injured infants and children.  She has conducted clinical research on the use of telemedicine to enhance overnight communication betweeen the on-call attending and the bedside care team.  She has also studied the use of telemedicine to connect parents at work or home with the PICU team during and after patient care rounds to enahnce communication and support family-centered care.  Currently, she is conducting research on the use of telemedicine to facilitate remote simulation-based team training exercises for medical providers caring for children  in the outlying community.  Beyond her interests in telemedicine, Dr. Yager is conducting two additional studies focusing on the use of innovative technologies 1) to improve placement of peripherally inserted central catheters (PICC) with less sedation and radiation exposure; and 2) to improve the accuracy with which critical events  are documented in the hospital setting.
