This Trauma Team Activation Criteria Guideline defines the minimum patient criteria for full or modified trauma team activation. Additional criteria may need to be added based on local hospital resources. Full Trauma Team Activation refers to automatic activation of the entire trauma team, including the general-trauma surgeon, based on predefined criteria. Modified Trauma Team Activation allows for initial activation of a portion of the trauma team (usually excluding the general-trauma surgeon) with subsequent activation of the full team if necessary.
