The Incidence and Risk Factors of Postoperative Delirium

February 9, 2022 updated by: Youn Joung Cho, MD, PhD, Seoul National University Hospital

The Incidence and Risk Factors of Postoperative Delirium in Elderly Patients Undergoing Spine Surgery

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.
