Researcher | Research Overview
Dr. McManus' work aims to identify, understand, and overcome access barriers to critical hospital services. He and colleagues use large datasets, simulation modeling, and systems research tools to solve complex problems in emergency departments, operating rooms, and intensive care units. His Robert Wood Johnson-funded research provided solutions for the ambulance diversion crisis in Massachusetts and subsequent studies of surgical scheduling improved access to intensive care units. Current work focuses on hospital capabilities, networks of care, and the differential impacts of health system change on children.
Researcher | Research Background
Dr. McManus obtained his MD from Northwestern University and MPH in Health Policy and Management from the Harvard School of Public Health. He completed residencies in Pediatrics (Boston Children's Hospital) and Anesthesiology (Massachusetts General Hospital), followed by fellowship training in Pediatric Anesthesia and Critical Care (Boston Children's Hospital). He is currently a Senior Associate in Anesthesia and Critical Care at Boston Children's Hospital and Associate Professor at Harvard Medical School. Dr. McManus is past president of the Massachusetts Chapter of the AAP, member of the AAP Committee on State Government Affairs, and, during Massachusetts health care reform, served as the Governor’s pediatric representative on the Massachusetts Cost and Quality Council Advisory Committee.
