Factors Influencing Sleep Disturbances among Critical Care Nurses: A Cross-Sectional Study

Background: Sleep disturbances among critical care nurses have been widely recognized as a significant concern, affecting both individual well-being and patient care outcomes. Understanding the factors influencing sleep quality in this population is crucial for developing effective interventions and policies to promote better sleep health. Objective: This cross-sectional study aimed to investigate the demographic and work-related factors associated with sleep disturbances among critical care nurses in Jordan. Methods: A total of 182 critical care nurses from governmental, private, and military healthcare sectors in Jordan participated in this study. Data were collected using a structured questionnaire, including demographic variables and the Arabic version of the Insomnia Severity Index (ISI). Descriptive statistics and inferential analyses, including independent t-tests and ANOVA tests, were conducted to identify factors influencing insomnia severity among critical care nurses. Results: The study findings revealed a moderate level of insomnia severity among critical care nurses, with several demographic and work-related factors significantly associated with sleep disturbances. Educational level, smoking status, regular physical activity, weekly working hours, and working overtime were identified as significant predictors of insomnia severity among participants (all p <0.05). Conclusion: Our study underscores the importance of addressing various demographic and occupational factors in understanding sleep disturbances among critical care nurses. Targeted interventions aimed at promoting better sleep hygiene and addressing modifiable risk factors are essential for improving sleep quality and overall well-being in this vital healthcare workforce.
