Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Incidence of postoperative delirium
Time Frame: Within 7 days after surgery. Delirium at any time during the 7 days after surgery was considered postoperative delirium.
Postoperative delirium was assessed using the 3D-CAM scale. It consists of 4 features, and a positive feature 1 and 2 plus 3 or 4 is considered postoperative delirium.
Within 7 days after surgery. Delirium at any time during the 7 days after surgery was considered postoperative delirium.
