There are shortcomings to the current TBI grading system because it does not consider other factors relevant to patient outcome. In 2025, a new TBI classification framework called CBI-M was announced and is starting trials in trauma centers. This proposed new model will use clinical, biomarker blood tests, imaging, and modifiers based on the patient’s individual factors like existing medical conditions, environmental factors, and how the injury occurred. It’s unclear what labels this new CBI-M framework may assign for severity as it will likely go through further refinement and validation.
