title: Postconcussion Symptoms as a Marker of Delayed Recovery in Children and Youth Who Recently Sustained a Concussion: A Brief Report.
abstract: OBJECTIVE
  To identify predictors of delayed recovery in children who sustained a concussion and sought care in a pediatric hospital.
  
  
  METHODS
  Retrospective cohort study design.
  
  
  METHODS
  Montreal Children's Hospital Concussion Clinic database.
  
  
  METHODS
  Children who sustained a concussion and sought care within 10 days of the injury, with complete medical history and Postconcussion Symptom Scale (PCSS) score available.
  
  
  METHODS
  Total symptom score on the PCSS, sex, age, history of concussion, sleep disturbances, anxiety, learning disabilities, attention problems, and depression.
  
  
  METHODS
  Delayed recovery (28 days or more).
  
  
  RESULTS
  A total of 213 children (F = 76, M = 138) with a mean age of 13.89 ± 2.55 years were included. Only total PCSS score at 10 days postinjury was identified as a significant predictor of delayed recovery (odds ratio: 1.019, P = 0.01).
  
  
  CONCLUSIONS
  This study demonstrates the potential for clinicians to identify, with the sole use of the PCSS, children at risk of experiencing symptoms for longer periods of time.
