Abbreviated Injury Scale

The Abbreviated Injury Scale (AIS) is a medical tool used to assess the severity of individual injuries sustained by a person, especially in accidents or trauma cases. It assigns a numerical score from 1 to 6, where 1 indicates a minor injury and 6 signifies a maximum or unsurvivable injury. This standardized system helps healthcare providers quickly evaluate injury severity, prioritize treatment, and analyze data for research or safety improvements. Essentially, AIS provides a common language for describing how serious injuries are, facilitating better communication and decision-making in emergency care and trauma management.
