This study is a retrospective analysis of a large-scale multicentre prospective cohort study that investigates the the relationship between Preoperative Anxiety and Postoperative Delirium in Elderly Chinese Patients: a Multicenter Prospective Cohort
This is a retrospective cohort study using prospective data from a multicenter database. 8000 elderly patients undergoing elective non-cardiac or non-neurosurgical surgery were included in this study. The Generalized Anxiety Disorder Scale (GAD-7) was used to measure preoperative anxiety symptoms. The confusion assessment method (3D-CAM) was used to assess postoperative delirium in elderly patients undergoing non-cardiac surgery. If the patient is discharged, follow up by phone or email. Binary logistic regression analysis and propensity score matching (PSM) and subgroup analysis were used to analyze the data.
