Went to a green at a GP surgery, mid morning, for a female with abdo pain. Just as we got on scene we got shouted up and the job had been re-prioritised to a red. Went in and the receptionist told us the patient had been in the waiting room but was currently in the toilet. When she came out the receptionist gave us the GPs letter and I asked why they had phoned back for a regrade. She said the GP must have thought it was getting worse. The patient had a history of abdo pains (psyche related) and was on numerous things for "the problem". Yet that was regraded to a red after we were on our way and we didn't see the GP once. Got an urgent to an elderly female with acute SOB. Shouted up and said are you sure this is an urgent and they said to run with it while they contacted the GP cos they thought it was a bit suss. GP said she wanted the lady in A&E ASAP as her breathing was quite bad. She thought urgent meant do it now, urgently. You just can't educate some people.
