Objective: This narrative review aims to synthesize and examine the interrelationships between critical care nurses' exhaustion, job burnout, work conditions, task volume, and their perceptions of the patient safety climate.


Methods: A narrative review of the extant literature was conducted. Databases and relevant journals were searched for studies focusing on ICU nurses, burnout, work environment, workload, and patient safety climate. Key findings were synthesized to identify themes and evidence-based relationships.


Results: The evidence consistently demonstrates a strong negative correlation between burnout components (emotional exhaustion and depersonalization) and positive perceptions of patient safety culture. Conversely, a sense of personal accomplishment and a supportive work environment are positively associated with a robust safety climate. While the direct link between task volume and safety perceptions is sometimes attenuated, high workload is a significant driver of exhaustion and burnout, thereby indirectly eroding the safety climate. Fatigue is identified as a critical precursor that impairs cognitive function and diminishes safety performance.


Conclusion: The well-being of the critical care nurse is inextricably linked to the safety of the patient. Burnout, poor work conditions, and excessive task volume collectively threaten a positive safety climate. Healthcare organizations must implement multifaceted, systemic strategies that address burnout, optimize the work environment, manage fatigue, and empower nurses to foster a culture of safety. Proactive leadership is required to safeguard both caregiver well-being and patient outcomes.
