Dr. David Gibney:

When I worked in the UK there was a protocol which was, for example, when someone has a headache then one must look for certain red flags. If there are no red flags one tries analgesia to see if the headache goes. There are certain steps to go through. If the steps are gone through and the headache persists and if there are no signs of anything acute, that case needs to go to hospital straight away as there could be some underlying pathology and there would be access to an MRI without having to wait to see a neurologist. That is what I mean.
