The Incidence and Risk Factors of Postoperative Delirium

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.

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.

Inclusion Criteria:

• Patients who underwent spine surgery between September 2016 and August 2018 at Seoul National University Hospital

Exclusion Criteria:

• Patients who had no information on postoperative care and managements.
