Comparing PROMIS Global Health and Rivermead Post-concussion Symptoms Questionnaire in adult traumatic brain injury.

Of 372 screened patients, 216 met inclusion criteria.

Median age was 58 years (IQR 39-73); 67% were male; 84% had mild traumatic brain injury by admission Glasgow Coma Scale; 51% had polytrauma.

Patient-Reported Outcomes Measurement Information System domains showed consistent inverse correlations with RPQ burden (ρ -0.41 to -0.68; all p < 0.001), strongest for Patient-Reported Outcomes Measurement Information System total versus RPQ-13 (ρ = -0.68) and RPQ total (ρ = -0.67).
