The effect of nursing care provided to coronary intensive care patients according to their circadian rhythms on sleep quality, pain, anxiety, and delirium: a randomised controlled trial
Abstract
This study carried out to examine the effects of nursing care given to coronary intensive care patients according to their circadian rhythms on sleep quality, pain, anxiety, and delirium. This study was designed as a randomised controlled, clinical investigation. The study population consisted of patients treated in the coronary care unit of a training and research hospital between September 2022 and February 2023. Total of 44 participants were included. The included participants were followed up for 3 days in the coronary intensive care unit. Data were collected using “Patient Information Form, Sleep Quality Scale in Coronary Intensive Care Patients (SQ-CC), Visual Analogue Scale (VAS), Morningness-Eveningness Questionnaire (MEQ), Hospital Anxiety and Depression Scale (HADS), Intensive Care Delirium Screening Checklist (ICDSC).” In addition, melatonin and cortisol measurements were made, and sleep data were taken with a smartwatch. Patients with intermediate chronotype, delirium, on ventilator support, or using sedative drugs were excluded. The chronotypes of the participants were determined, and the patients in the intervention group were given nursing care by their circadian rhythms. No intervention was made to the control group, and their routine care was continued in accordance with intensive care unit functioning. Frequency distribution, dependent and independent sample t-test, Wilcoxon test, repeated measures analysis of variance, Mann Whitney U, and chi-square…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 44 participants or records.
