Key Points

A PCSI cut point of 23 effectively distinguishes between adolescents with and without a recent concussion, enhancing identification accuracy.
Statistical analysis reveals that a cut point of 23 serves as a useful threshold for assessing concussion symptoms.
The study used observational analysis to examine the diagnostic effectiveness of the PCSI in identifying concussion cases.
Early identification of concussions using the PCSI can improve management and treatment strategies for affected adolescents.

Implication

Observational analysis finds a PCSI cut point of 23 distinguishes concussion presence in adolescents, suggesting improved diagnostic accuracy.

Abstract

Our results suggest a PCSI cut point of 23 can distinguish between adolescents with/without a recent concussion and may provide enhanced accuracy to identify a suspected concussion in the subacute time after injury.
