The OIS grading scheme is fundamentally a progressive scale of anatomic injury within an organ system or body structure. The goal of developing such a scale is to provide a common language to facilitate clinical research and continuing quality improvement. The OIS is not specifically designed to correlate with morbidity, mortality, disability, or other patient outcome indices. Moreover, the OIS concept does not include the significant physiologic variables that may profoundly influence outcome-age, pre-existing disease, acute blood loss, time from injury to definitive care, or associated injuries. However, the OIS may be substituted for similar components of more complex models, e.g., the Abdominal Trauma Index, to be predictive for outcome. Finally, we emphasize that this first generation of OISs represents an initial attempt at classification that will no doubt warrant modification as improved diagnostic tools become available and the OISs are tested with clinical experience.
