Rates of concussion have doubled during the last decade, with an estimated 750,000 pediatric acute concussion visits to emergency departments (EDs) occurring annually in the United States. Although many children experience symptom resolution within 2 weeks, approximately 33 percent experience ongoing symptoms, and those that persist beyond 28 days are referred to as persistent postconcussion symptoms (PPCS), which can have serious adverse effects, resulting in school absenteeism, impaired academic performance, depressed mood and lower quality of life. Validated and pragmatic tools to identify children at high risk of developing PPCS did not previously exist.

Dr. Zemek and his team conducted a study to derive and validate a clinical risk score to stratify PPCS risk occurring after acute concussion in youth using readily available clinical features. The study included children and adolescents (age 5-<18 years) who presented within 48 hours of an acute head injury to a pediatric emergency department, with follow-up 28 days after the injury.   This is the largest concussion cohort in the world with 3,063 patients enrolled.  Dr. Zemek will discuss the results and implications of this study.  Future clinical benefits of the findings might include identifying high-risk individuals for further screening, prioritization for specialized concussion evaluations, and initiation of emerging treatments to prevent PPCS.

Dr. Roger Zemek

Roger Zemek, MD, is a Pediatric Emergency Physician practicing at the Children’s Hospital of Ontario (CHEO) in the Emergency Department as well as a Scientist in the CHEO Research Institute.  He completed his undergraduate studies in Applied Mathematics at Yale University, and his medical school and pediatric residency at Columbia University in New York City.  He moved to Canada for his Pediatric Emergency Medicine fellowship training at McGill.  He is an Associate Professor in the Departments of Pediatrics and Emergency Medicine and holds a Clinical Research Chair in Pediatric Concussion at the University of Ottawa.  He is the Director of Clinical Research at CHEO, and is the Vice-Chair of the Pediatric Emergency Research Canada (PERC) network. He is the principal investigator on multiple federal peer-reviewed grants, with expertise in pediatric concussion.  He led the largest concussion study in the world to date examining the predictors for Persistent Post-Concussion Symptoms in children suffering a concussion, and led an international team for the development of guidelines for the management of pediatric concussion.
