A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational project aims to explore the relationship between various factors and the development of postoperative delirium in older patients. It will investigate the internal circadian time, heart rate variability, and other secondary goals to gain insights into their associations with delirium rates. The study will analyze data from patients who have previously participated in the QC-POD program, focusing on perioperative conditions and physiological parameters. By examining these connections, the project seeks to enhance the understanding of delirium in the surgical context.
