Our review in the North came up with the idea of hospital systems, which are intended to shift people's perception of hospital services as somehow being bricks and mortar located in a particular place. The idea of systems was that each would serve a population of 350,000 to 500,000. Acute episodes would be treated at the centre of the cluster, while it would also be possible to move in the opposite direction. This opens up enormous possibilities for a local centre, whether it is called a hospital, polyclinic or something else, given that a great deal of diagnosis can be performed using imaging and telemedicine.
