Predicting the Unpredictable: Development and External Validation of the GO SOAR Surgical Risk Calculator for Data-Driven Predictions of Surgical Complications in Gynaecological Oncology Surgery
Abstract
Simple Summary Accurate preoperative surgical risk predictions help predict potential postoperative complications, guide shared doctor–patient decision making, and personalise management strategies to improve perioperative surgical outcomes. We present the development and external validation of the novel GO SOAR surgical risk calculator using global prospective data across all income healthcare settings. At a clinically significant 90% specificity threshold, it achieved the highest observed sensitivity among the evaluated all-purpose universal surgical risk calculators commonly used as part of routine clinical practice, and is easy to use, minimizing intensive data entry and physiological parameters and laboratory tests, ensuring benefits to women globally irrespective of resource availability.
