EFFECT OF CYCLED LIGHT MODIFICATIONS ON SLEEP QUALITY AND DELIRIUM AMONG PATIENTS

Abstract

Background: Inadequate sleep and delirium are common conditions among critically ill patients in the intensive care unit (ICU), which have negative consequences on their health outcomes. Aim of the study: The study aimed to identify the effect of cycled light modifications on sleep quality and delirium among patients. Tools: Richards-Campbell Sleep Questionnaire (RCSQ) and the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) were used. Study sample: A purposive sample of 100 available medical and surgical ICU patients were included. Results: The results showed significant improvements in sleep parameters, including sleep depth, sleep latency, number of awakenings, sleep efficiency, sleep quality, and overall sleep quality (P < 0.001). The CAM-ICU assessment showed a substantial decrease in positive delirium cases across specific features, including an acute onset or fluctuating course, inattention, and altered consciousness, while disorganized thinking displayed a significant increase in positive delirium cases (P < 0.001). The overall CAM-ICU assessment revealed a significant shift, with positive delirium cases decreasing from 20% to 0% (P < 0.001). Conclusion: The study highlights the effectiveness of cycled light modifications in improving sleep quality and mitigating delirium among ICU patients. Recommendation: Application of cycled light modifications for ICU patients to promote sleep quality and decrease delirium.
