Development of a nomogram predicting postsurgical intra-abdominal infection in blunt abdominal trauma patients

A clinical model was developed to predict postsurgical intra-abdominal infection in blunt abdominal trauma patients based on a retrospective analysis of 553 patients from 7 medical centers. Independent risk factors were identified, including age, prehospital time, c-reactive protein, injury severity score, operation duration, intestinal injury, neutrophils, and antibiotic use. The nomogram showed good predictive performance in both derivation and validation cohorts, indicating potential for clinical application in guiding treatment decisions.
