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 . In the parallel universe of emergency medicine access block or delays in admission of patients to hospital inpatient areas from EDs can be described as a whole system problem the equivalent to the Theory of Everything . It remains a fundamental challenge prompting comments such as Access Block and ED overcrowding have created a dynamic tension and the future of emergency medicine will be determined by the resolution of this conflict 2 . Despite access block and overcrowding in EDs being redefined investigated and managed in multiple ways it is far from being resolved 3 4 . This chapter summarizes the evidence from access block studies exploring hospital patient or medical interventions to reduce the impact of access block in terms of ambulance .
