Except general people should be using pharmacists; in-hours GPs or out of hours doctors and walk-in-centres; and minor injuries units. A&E should be reserved for emergency care. There's a very small percentage of people who need an A&E department and this app would be great for them, but please don't send people who are not in an emergency to A&E.
Thanks for the links. I'd like to help build a world where people have access to useful information as easily as possible. Of course, with ease of access to information people will need to become more responsible. I'm hopeful we can get there :)
