Predicting Postoperative Complication Risks

To effectively identify patients who may/may not be at risk for one or more postoperative complications in a dynamic, real-time setting, and generalize the detection to different types of surgeries, rather than an Early Warning Score [15] focusing on very specific complications, we propose to use pre-, intra- and post-surgery data to make interpretable risk predictions about who is likely to have complications, which complications may occur, and when in the postoperative setting.
