Our gp surgery has an appointment system where you have to phone when they open at 8am and ask for a callback from the doctor. The doc then rings you at some point during the day and determines whether or not you need to go in.
It's always really busy and by 8.05 the appointments are all gone. They do have a number of 'emergency appointments' each day but the phone message says they are for life threatening cases and not to abuse the system by trying to book one if this isn't the case. Surely if it's life threatening you'd be phoning 999 and not waiting in a phone queue for the GP? What constitutes a gp emergency?
