Summary

This study followed 610 adults who had heart surgery to see how often they develop postoperative delirium—a sudden state of confusion that can come and go. Researchers collected information on known risk factors like age, high blood pressure, and diabetes, and tracked outcomes such as length of hospital stay and recovery. The goal was to better understand delirium after cardiac surgery so it can be spotted and treated earlier.
