Frequently asked questions
5P score / Risk of persistent symptoms after concussion: What does this calculator compute?
5P score (Predicting and Preventing Postconcussive Problems in Pediatrics, Zemek 2016, JAMA) for children aged 5 to under 18 years with concussion seen in the emergency department within 48 hours: age, sex, prior concussion, migraine, answering questions slowly, tandem stance, headache, sensitivity to noise and fatigue give 0 to 12 points. This yields the estimated risk that at least 3 symptoms are still present after 28 days: low (0 to 3), medium (4 to 8) or high (9 to 12). Moderate discrimination (AUC 0.68).
