We went to an elderly lady whom a GP had visited at home. A first responder was on scene by the time we had got there and the GP had just left before we arrived. The GP had her notes and knew the lady. This 999 response was due to the lady suffering with D&V and the GP had booked her into the Medical Assessment Unit (MAU) - bypassing A&E. We got her onto the ambulnace and began taking some history ourselves such as, 'when was the last time she had either D or V, to which she replied she'd had neither. All she had had were terrible pains in her back. We very quickly ascertained she ahd an abdominal aortic anneurysm which needed immediate surgical attention, so we duly alerted the nearest A&E & bypassed the MAU. It was known to the GP that she had an anneurysm, but he neglected to inform us of any such history. The lady was in surgery within an hour of our arrival - damn we're good!
