Effect of a Nurse-Led Environmental Stressor Reduction Package on Perceived Stress and Sleep Quality in Intensive Care Unit Patients

This study aims to evaluate the effectiveness of a nurse-led "Environmental Stressor Reduction Package" on critically ill patients' perception of environmental stress and their sleep quality in the intensive care unit (ICU). The package includes multi-component interventions such as reducing noise levels, adjusting lighting according to circadian rhythm, maintaining thermal comfort, limiting visitor traffic at night, and organizing nursing care to minimize sleep disruption. A structured "Quiet Night Checklist" will be used to monitor the implementation of these interventions during night shifts. The study will be conducted in the 10-bed anesthesia and reanimation intensive care unit of Ümraniye Training and Research Hospital, İstanbul. Eligible adult patients who are awake, not under sedation, and able to communicate will be recruited. Participants in the intervention group will receive the Environmental Stressor Reduction Package for at least two and up to five consecutive nights, while the control group will continue to receive standard ICU care. Outcomes will be measured using two validated tools: The Intensive Care Unit Environmental Stressor Scale (ICUESS) to assess perceived environmental stress. The Richards-Campbell Sleep Questionnaire (RCSQ) to evaluate self-reported sleep quality. The findings of this study are expected to contribute to evidence-based nursing interventions in the ICU setting, by improving patients' sleep quality and reducing stressors associated with the intensive care environment.
