Summary

This study will develop a computer model that uses machine learning to predict a patient's risk of developing acute kidney disease after heart surgery. Researchers will collect data from 820 adults undergoing certain heart procedures to build and test the model. The goal is to create an online tool that helps doctors quickly assess individual risk and personalize care, potentially improving recovery and reducing costs.
