The Abdominal Trauma Index—A Critical Reassessment and Validation

Abstract
The Abdominal Trauma Index (ATI) was devised to quantify the risk of complications following abdominal trauma. With scores greater than 25, the risk fo postoperative complications became exponential. The purpose of the present study was to determine if: 1) the organ risk factors previously assigned were more statistically valid; and 2) the addition of physiologic variables would enhance the prediction of postinjury intra-abdominal sepsis.
