A Clinical Trial of a Novel Electroencephalography Device as a Predictor of Postoperative Delirium

Pdf Summary

Postoperative delirium is a concerning issue for older surgical patients, prompting the need for a reliable perioperative neurocognitive assessment tool. This study explored using a novel electroencephalography (EEG) device, WAViMedTM, to predict postoperative delirium. While no direct association was found between P300 auditory-evoked potentials obtained using WAViMedTM and Montreal Cognitive Assessment (MoCA) scores, further investigation is recommended. The study highlights the importance of assessing baseline cognitive function before surgery in older patients and the potential impact on patient outcomes and healthcare costs. The ideal perioperative cognitive screening tool should be fast, valid, reliable, automatically scored, culturally unbiased, cost-efficient, and not impacted by language or education levels, although such a tool currently does not exist. The research focused on tracking neurocognitive changes using EEG technology to predict and monitor perioperative neurocognitive impairments. Despite the study's limitations, future research with larger sample sizes and diverse patient populations is necessary to fully determine the clinical utility and feasibility of POC EEG devices in the perioperative setting. The study emphasizes the need for continued inquiry into novel tools for neurocognitive assessment in older surgical patients to improve outcomes and reduce healthcare costs.
