The Incidence and Risk Factors of Postoperative Delirium

Completed

• Conditions: Delirium in Old Age

• Registration Number: NCT04656379
• Lead Sponsor: Seoul National University Hospital

Brief Summary

Delirium is known to be one of the most common postoperative complications in elderly patients undergoing surgery. Because postoperative delirium can affect the length of hospital stay and prognosis significantly, it is important to identify the risk factors for postoperative delirium in advance. However, there have been few reports concerning intraoperative modifiable risk factors, such as postoperative pain, for postoperative delirium.

Detailed Description

In this observational study, we will review the electronic medical records of elderly patients underwent spine surgery and assess the incidence and risk factors for postoperative delirium.
