Access block and emergency department overcrowding

Access block affecting the emergency department (ED), also known as boarding in the United States and Canada, can be described as a phenomenon comprising almost all the challenges in the world of modern EDs. We use the analogy of parallel universes to illustrate both the complexity and the severity of the problem. In the world of physics, many attempts have been made to create a mathematical solution that can answer the more basic questions about physical phenomena in the universe. This has been known as ‘Theory of Everything’. Albert Einstein spent 30 years of his life trying to solve this ‘Theory of Everything’, but failed [1].
