Glasgow Outcomes Scale Extended (GOSE) ratings for traumatic brain injury (TBI) obtained via questionnaires and via interviews had overall good agreement, and interviews did not offer advantages over central scoring of a patient- or caregiver-reported questionnaire.
Why this matters
While interviews are considered the gold standard for assessment of global functional outcomes in acute TBI, several trials have used a patient- or caregiver-completed GOSE questionnaire.
Comparative trials for interviews versus questionnaires have been small and inconclusive.
This study supports the use of questionnaires in trials, which may offer practical advantages over interviews in some situations.
