Randomized Controlled TrialReliability of a telephone-based Glasgow Outcome Scale assessment using a structured interview in a heterogenous population of patients and examiners.
A reliable telephone-based Glasgow Outcome Scale (GOS) assessment would be advantageous to both patients and investigators. Using a previously published structured GOS interview and scoring system, the aim of this study was to assess the reliability of telephone-based GOS scores compared to those obtained face-to-face in a heterogenous population of patients and examiners. Sixty-six patients hospitalized for a variety of acute neurological injuries underwent two GOS interviews approximately 90 days after injury. ⋯ Patient-, examiner-, and interview-related characteristics had no significant associations with GOS concordance, although patient sex had a significant association with discrepant responses to one specific question (work at previous capacity). When used by multiple examiners to assess patients with diverse neurological conditions, use of a structured GOS examination does not guarantee a reliable telephone-based GOS score. Determination of whether patient sex influences the validity of the structured face-to-face GOS interview is worthy of future study.
