The Standardized Assessment of Concussion (SAC), a sideline mental status assessment tool, was used for the U.S. Naval Academy football team. Baseline SAC data were obtained for 298 subjects; the SAC was also used in immediate assessment and subsequent monitoring of 21 concussed players. Analysis of baseline data revealed no significant difference in SAC score based on position on team, position category (offense, defense, or special team), test form used, graduating class year, or history of prior concussion, nor was there any correlation on the basis of age. Among injured players, there was a significant drop in mean SAC total score from baseline to immediately following concussion. Surveys by athletic trainers and physicians who used the SAC indicated that, despite identifying potential limitations, they considered it to be easy and quick to administer and a useful tool in the assessment, monitoring, and management of concussed athletes at U.S. Naval Academy.
