- They all come from your own clinics, so could they come from "St Bartholomew's Hospital" rather than from "3-7 Giltspur St, City of London"?
- In realty there would be some choice, or system, about where they go, could you select a destination as you do with normal ambulance transports?
- Could they need a specific service, i.e. "Traumatology" or "Cardiac Surgery"?
- Some of them might need Critical Care?
