A new paradigm for retrieval medicine.

A number of new time critical medical interventions are highly specialised. As such, they are not available in many hospitals and EDs. This necessitates transfer to another facility, which is often associated with some degree of delay. Processes to facilitate timely access to these interventions should aim to replicate or improve on that which would have been available should the patient have been in the community, and responded to, primarily, by an emergency medical service.
