The Impact of Virtual Reality Technology on Delirium, Sleep Quality, and Negative Emotions in Critically Ill Patients in the ICU

Introduction

To investigate the effects of virtual reality technology on delirium, sleep quality, and negative emotions in critically ill patients in the intensive care unit (ICU), with the aim of assessing its potential application in clinical nursing

Method

A cohort of critically ill patients in the ICU underwent virtual reality interventions, which included immersive virtual environment experiences designed to alleviate patient anxiety and discomfort. Pre- and post-intervention assessments were conducted using the delirium assessment scale, the Pittsburgh Sleep Quality Index (PSQI), and a negative emotion scale to compare changes and quantify the effects of virtual reality technology.

Results

Following the intervention, the incidence of delirium significantly decreased, with patients’ scores on the delirium assessment scale showing a notable decline compared to pre-intervention levels (P<0.05), indicating a positive effect of virtual reality interventions in the prevention of delirium. In terms of sleep quality, patients demonstrated significant improvements in PSQI scores post-intervention (P<0.01), reflecting the effectiveness of virtual reality technology in enhancing sleep quality. Additionally, scores on the negative emotion scale also significantly decreased (P<0.01), indicating a substantial alleviation of patients’ anxiety and depressive symptoms.

Discussion

Virtual reality technology exhibits significant intervention effects in the nursing care of critically ill patients in the ICU, effectively reducing the incidence of delirium, improving sleep quality, and mitigating negative emotions. This technology offers an innovative psychological intervention approach for critically ill patients, demonstrating promising clinical application prospects that warrant further promotion and research in future nursing practice.
