Preoperative Cognitive Impairment Predicts Postoperative Delirium

Status Completed

Clinical Trial Summary

Preoperative cognitive impairment (PCI) may increase the incidence of postoperative delirium (POD), yet screening for cognitive impairment is rarely performed. This study hypothesized that Mini-Cog for preoperative cognitive impairment screening predicts postoperative delirium. Elderly patients (65 years or older) attending Henan Provincial People's Hospital during the trial period who required elective thoracic surgery were recruited into the study.

Clinical Trial Description

We collected data points on demographics and hospital episodes through the electronic medical record the day before surgery. Cognitive function screening (Mini-Cog; the Mini-mental State Examination, MMSE), depression screening (Patient Health Questionnaire-9, PHQ-9), sleep quality assessment (Pittsburgh Sleep Quality Index, PSQI), and pain assessment (Numeric Rating Scale, NRS) were performed, and the time spent on Mini-Cog test and MMSE assessment was recorded. The Short Confusion Assessment Method (CAM) was administered once per day on postoperative days 1 to 5 to evaluate delirium. ;
