For those who are interested in my ORCON post, which is coming soon I thought you might want to see how the "Advanced Medical Dispatch System" (AMPDS) works.
Each call, when answered is categorised by the call taker using this computer based system. It is supposed to ensure that the most serious calls get an ambulance first. To be honest it doesn't seem to work "on the streets" as we get sent as a "Cat A" to someone who is upset, and yet someone who has had a stroke is only an Amber response. The fact that we use AMPDS is alright, but the Department of Health felt that it needed changing, and so the instruction from them is children under the age of 2 need a "Cat A" response. Which as this forum tells us results in fast cars being sent to children with constipation.

CAT A CALLS :

RED 1 - Actual death imminent (Unconscious not breathing)
RED 2 - Possible death imminent (Unconscious/not alert but breathing, or with other signs like mechanisim of injury)
RED 3 - Risk of imminent death (breathing and conscious but at high risk)

N.B. All calls to children aged 2 and under automatically get a "RED 3" regardless of diagnosis.

CAT B CALLS :

AMBER 1 - Definitely serious (not immediately life threatening ,but requires urgent on scene assessment ,treatment and conveyance)
AMBER 2 - Possibly serious (not immediately life threatening and no specific gain from immediate treatment on scene or in an A&E)

CAT C CALLS :

GREEN 1 - Requiring assessment and or transport (not life threatening or serious, but needs assistance)
GREEN 2 - Suitable for telephone triage and or advice (probably no need for transport telephone consultation can be used to determine the health care needed)
