Official title

Preoperative Depression and Postoperative Delirium in Older Chinese Adults: A Multicenter Retrospective Cohort Study

Overview

This study is a retrospective analysis of a large-scale multicentre prospective cohort study that investigates the impact of preoperative depression on the incidence of postoperative delirium among elderly Chinese patients undergoing non-cardiac major surgery.

Detailed description

Preoperative depression is common among elderly surgical patients and may adversely affect postoperative outcomes. However, there is limited research on the relationship between preoperative depression and postoperative delirium (POD) in elderly patients undergoing non-cardiac major surgery. This study retrospectively analysed data from a prospective database (PDCEP) of patients aged 65 and above who underwent non-cardiac major elective surgery in multiple tertiary hospitals across 10 provinces in China. The study period spanned from April 1, 2020 to April 30, 2022.

Preoperative depression was assessed using the Patient Health Questionnaire-9 (PHQ-9), with PHQ-9 \> 5 defined as the depression group and PHQ-9 \< 5 as the non-depression group. Postoperative delirium was evaluated using the 3-minute Diagnostic Interview for CAM (3D-CAM). Binary logistic regression analyses were conducted, and propensity score-matching (PSM) and subgroup analyses were also applied.

Primary outcome measures

  • Postoperative Delirium [Time frame: Delirium within 7 days of surgery]
Secondary outcome measures (2)
  • Postoperative Acute Pain [Time frame: Pain within 7 days of surgery]
  • Postoperative Pulmonary Infection [Time frame: Within 7 days of surgery]

Eligibility criteria
