Current State of Critical Care Nursing Worldwide: Current Training, Roles, Barriers, and Facilitators.

This review provides insights on the current state of roles and responsibilities, on-the-job training, barriers, and facilitators of critical care nursing (CCN) practice. Some of the established roles and training of CCN were providing care for acutely ill patients, delivering expert and specialist care, working as a part of a multidisciplinary team, monitoring, and initiating timely treatment, and providing psychosocial support and advanced system treatment, especially in high-income countries. In low-resource settings, critical care nurses work as health care assistants, technical or ancillary staff, and clinical educators; manage medications; care for mechanically ventilated patients; and provide care to deteriorating patients.
