Study design
RECRUITMENT
This randomized controlled study was conducted in the tertiary ICU of the Health Sciences University, Izmir Tepecik Training and Research Hospital. The tertiary ICU has a capacity of 41 beds and is staffed by physicians with at least four years of experience in full-time intensive care. All clinicians participating in the study had advanced intensive care training and were familiar with the clinic's current protocols, with at least two experienced doctors covering the night shifts each day. In the enrollment process, 102 patients were assessed for study eligibility. The assessment was carried out between March 1, 2021 and March 1, 2023. By choosing this timeframe, we took into account changes in the admission of patients and ensured transparency in the recruitment process. The study included patients who were hospitalized during this period and met the eligibility criteria. This study was approved by the Institutional Review Board and Ethics Committee of the Health Sciences University İzmir Tepecik Training and Research Hospital, and written informed consent was obtained from patients’ family members.
