Floating to intensive care units: Nurses' messages for instant action to promote patient safety.

Background: The overwhelming number of patients admitted to intensive care units (ICUs) combined with a nursing staff deficit sometimes requires the redeployment of nurses from other areas, meaning non-critical care nurses are asked to assist in treating critically ill patients. This may affect patient safety, especially in poorly resourced ICUs with financial constraints, such as in some developing countries. Nurses and nurse managers need specific strategies to address this issue and ensure patient safety.
