About Michael Flaherty, DO

Michael Flaherty is a pediatric critical care physician in the pediatric intensive care unit (PICU) at MassGeneral for Children and a leading researcher in the field of pediatric injury prevention and epidemiology. He grew up in North Andover, MA and attended Emmanuel College in Boston where he obtained a B.S. in biology and chemistry. He went on to obtain his medical degree from the University of New England College of Osteopathic Medicine in Biddeford, ME and returned to Massachusetts to complete his residency in pediatrics at the Baystate Medical Center/Tufts University program.

During residency, he became interested in pediatric injury prevention research, and was part of the first group to study graduated driver licensing for the prevention of adolescent motor vehicle fatalities in Massachusetts. He went on to complete his fellowship in pediatric critical care medicine at Massachusetts General Hospital where he became involved with the Trauma and Injury Prevention Outreach Program where he is now co-director. He stayed on as faculty at MassGeneral for Children where he continues research in pediatric trauma and injury prevention, as well as maintains active interests in medical education. His clinical interests include the care of critically ill children in all capacities, as well as specifically in the medical treatment of pediatric trauma victims, and the treatment of severe refractory asthma.

My active research interests are in the field of pediatric trauma and injury prevention.  I am particularly interested in the effects of health policies and legislation on preventing pediatric injury. I work with the MGH Trauma and Injury Prevention Program to investigate ways to decrease preventable injuries including sports-related concussion, off-road vehicle injuries, and teenage motor vehicle crashes. Our work has culminated in the first statewide analyses of the Massachusetts Off-Road Vehicle legislation, the strictest law in the United States for protecting young children from injury and death while operating off-road vehicles. We have also investigated the effects of sports-related concussion legislation on the practice and perceptions of pediatricians. I continue to seek out new and innovative ways to study the effect of legislation on injury prevention, as well as community outreach to promote awareness and prevention of common causes of childhood trauma.
