Quality of life as a mediating factor in the relationship between fatigue and perception of safety among critical care nurses in the United Arab Emirates

Abstract

Background: A scientific understanding of the relationships between intensive care unit nurses' well-being and patient safety will allow nurse managers, administrators, and policymakers to simultaneously manage crucial organisational goals of nurses' health and patient safety. Understanding predictors of fatigue among intensive care unit nurses may help to balance personal and organisational impacts (e.g., turnover intention, sick leave) and provide a way to positively influence their safety perception.

Objective: The aim of this study was to explore the association between work fatigue and perception of patient safety among nurses working in critical care units and determine whether their quality of life levels mediated this relationship.

Methods: This study used a cross-sectional correlational comparative design. Participants were a sample of 250 intensive care unit nurses recruited conveniently from three large hospitals in the United Arab Emirates. The self-reported questionnaire included the Nursing Quality of Life Scale, the Fatigue Severity Scale, and the Safety Attitudes Questionnaire (SAQ)-ICU version, as well as sociodemographic characteristics and work-related information.

Results: Of the 250 participating nurses, 76.8 % reported low QoL. There was a statistically significant correlation between nurses' Quality of Life and fatigue levels (r = 0.234, P = 0.000). Overall, 52.8 % of the sample had high fatigue and 49.6 % had poor safety perception. Multiple regression analysis using the Baron and Kenny approach showed that QoL, marital status, gender, and work environment were predictors of nurses' perception of safety.

Conclusion: Intensive care unit nurses had high levels of fatigue and poor Quality of Life. High Quality of Life and a favourable work environment were independent predictors of good patient safety perception. Efforts should be directed to maximize staffing resources that positively impact patient safety. These findings are comparable with international studies, suggesting that these issues may be ubiquitous.

Implications for clinical practice: Intensive care practitioners, managers and policymakers should adopt measures to modify intensive care nurses' exhausting working conditions and provide a supportive environment. these interventions might improve nurses' perception of patient safety and consequently prevent safety incidents.
