Predicting Persistent Postconcussive Problems in Pediatrics (5P)

Note: la description de ce programme de recherche est en anglais seulement.

One-third of children with concussion have ongoing physical, thinking, emotional or behavioral symptoms beyond one month, known as persistent post-concussion symptoms (PPCS).  PPCS may result in missed school, depressed mood, and lower quality of life.  In the Predicting Persistent Postconcussive Problems in Pediatrics (5P) study, the Pediatric Emergency Research (PERC) concussion team developed a PPCS risk score that was significantly better than the child’s physician at predicting future PPCS. The score incorporates nine clinical variables containing information from demographics, past medical history, initial signs and symptoms, and physical examination.  Clinicians are now able to provide accurate information to patients and families regarding the expected recovery, and researchers may target children at high risk for PPCS in new trials with the goal of preventing PPCS.
