A Retrospective review on the timing of Glasgow Coma Score documentation in a trauma database: implications for patient care, research, and performance metrics

The Glasgow Coma Score (GCS) is intended to be an objective, reliable measure of a patient's mental status. It is included as a metric for trauma registries, having implications for performance metrics and research. Our study compared the GCS recorded in the trauma registry (GCS-1) to that recorded in the neurosurgery consultation (GCS-2). This retrospective review compared GCS-1 to GCS-2. The Trauma Injury Severity Score (TRISS) method was used to calculate probability of survival (POS) for patients using both GCS-1 and GCS-2. GCS-1 significantly differed from GCS-2 (6.69 vs 7.84, ± 2.553, p
