Interest in Combining Intraoperative ElectroEncephaloGram (EEG) With Assessment of Frailty to Predict Postoperative Delirium in Patients Aged >75 Years Undergoing Major Non-cardiac Surgery

Centre Hospitalier Universitaire de Saint Etienne55 enrolled

Overview

Post-operative delirium (POD) is known to be independently associated with pre-operative frailty, pre-operative cognitive status and per-operative ElectroEncephaloGram (EEG). However, no study has focused on the impact of these pre- and peri-operative outcomes on the prediction of Post-operative delirium (POD). Therefore, this study has been designed to assess the performance of a new score that includes pre-operative frailty, and per-operative ElectroEncephaloGram (EEG) in predicting post-operative delirium.

Eligibility

Medical Language ↔ Plain English

Inclusion Criteria: * Patients of 75 yo or more undergoing a major non-cardiac surgery Exclusion Criteria: * Patients of less than 75 yo * Cardiac surgery * Minor surgery * Opposition to the study protocol * Presence of a delirium prior to the surgery

Outcomes

Primary Outcomes

Onset of an early Post-operative delirium (POD)

Investigation of an early Post-operative delirium (POD), with Confusion Assessment Method (CAM) criteria, 9-question test which assesses the presence, severity and fluctuation of nine clinical features of delirium, on a scale from 0 to 19. Higher scores indicate more severe delirium.
