| Abstract | Background: Nurses in intensive care units serve as a vigilant safety system and can save patients’ lives by identifying clinical problems at an early stage. However, nurses working in critical care environments are frequently exposed to disrupted sleep patterns and high levels of occupational stress, which may compromise vigilance and patient safety. Objectives: This study aimed to examine the associations between sleep health and perceived stress and subjective vigilance among nurses working in adult critical care units. Methods: This cross-sectional study was conducted in 2024 among nurses working in adult critical care units, including intensive care units (ICUs) and coronary care units (CCUs), at teaching hospitals affiliated with Kurdistan University of Medical Sciences, Iran. A total of 203 nurses were recruited using census sampling. Data were collected using self-report instruments, including a demographic information form, the Nurses’ Vigilance Questionnaire, Becker’s Sleep Health Questionnaire, and Cohen’s Perceived Stress Questionnaire. The normality of continuous variables was assessed using the Kolmogorov-Smirnov test. Descriptive statistics, including means, standard deviations, and frequencies, were calculated for all relevant variables. For inferential analyses, independent t tests, one-way analysis of variance, Pearson correlation coefficients, and multiple linear regression analysis were performed. Results: The mean scores for nurses’ vigilance, sleep health, and perceived stress were 147.91 ± 15.37, 10.65 ± 5.34, and 7.61 ± 2.87, respectively. Correlation analysis indicated that nurses’ vigilance was significantly positively correlated with sleep health (r = 0.552, P = 0.001), whereas perceived stress was significantly negatively correlated with nurses’ vigilance (r = -0.390, P = 0.001). Multiple linear regression analysis showed that shift type (B = -0.138, P = 0.04), sleep health (B = 0.427, P = 0.001), and perceived stress (B = -0.206, P = 0.002) were significant predictors of nurses’ vigilance. Conclusions: Given the critical role of nurses’ vigilance in delivering high-quality care, sleep health and perceived stress were significantly associated with subjective vigilance in adult critical care nurses. These findings suggest that interventions targeting sleep quality and stress management may improve vigilance and potentially enhance patient safety. | en |
