The scope of emergency nursing viewed through the lens of complex adaptive systems: A discussion paper

Across the world, emergency department nurses care for patients around the clock all year long. They perform tasks ranging from direct nursing care to managing patient flow, working in an environment characterised by interdependencies among numerous actors. The complex context in which emergency nurses operate has not been thoroughly described or discussed, indicating a knowledge gap. Hence, the aim of this discussion paper is to describe and discuss nursing in the emergency department and the connection between patient flow and nursing care, drawing on the concept of complex adaptive systems. The acts of direct patient care and patient flow, when viewed through the lens of complex adaptive systems, are central components of emergency nursing. Through a stepwise description of these two perspectives, based on literature and clinical experience from European countries, the paper illustrates the complexity of the emergency nursing context in a novel manner. We argue that direct patient care and patient flow, combined as patient flow management, constitute essential parts of the core of emergency department nursing. Further studies are needed to challenge or confirm this assertion.
