The study will also compare the predictive performance of this AI-based model with commonly used traditional risk scores.\n\nThe main questions it aims to answer are:\n\nCan an AI-based multimodal model predict major cardiovascular events within 30 days after gastrointestinal surgery? Does the AI-based model show better predictive performance than the Revised Cardiac Risk Index (RCRI), the American College of Surgeons National Surgical Quality Improvement Program Myocardial Infarction or Cardiac Arrest calculator (ACS NSQIP MICA), and the ACS NSQIP Surgical Risk Calculator (ACS NSQIP SRC)? Researchers will compare the AI-based multimodal model with traditional risk scores using measures of predictive performance, including discrimination, calibration, net reclassification improvement, and integrated discrimination improvement.\n\nParticipants will be adults undergoing gastrointestinal surgery. Researchers will review medical record data from patients treated in 2025 and will also collect the same types of clinical data prospectively in 2026. The clinical outcome being predicted is the occurrence of major cardiovascular events within 30 days after surgery. The study will not change routine clinical care.",[52,53,54],"Postoperative Complications","Cardiovascular Diseases","Digestive System Surgical Procedures",[56,57,58,59],"Major adverse cardiovascular events","Gastrointestinal surgery","Artificial intelligence","Multimodal model","2026-04-16",{"date":62,"type":63},"2026-04-20","ACTUAL",{"date":65,"type":63},"2026-01-01",{"date":67,"type":47},"2026-07-31",{"name":5,"class":6},1]
