Just a brief one.
I’ve just watched a video about paramedics/A&E support having to wait for hours outside A&E departments to handover (http://www.bbc.co.uk/news/health-25298066). The lady from the NHS was talking about pumping more money into the NHS – good idea – but putting it into the ambulance service to prevent the waits. To me, the obvious primary limiting factor is A&E capacity, and one solution (rather than changing the mindsets of people calling 999 unnecessarily) would be to increase the capacity of A&E departments, both numbers of staff and space, rather than increasing the queue of ambulances. By decreasing waiting times outside A&E, ambulances would spend more time on the road anyway.
