What is wrong is this - (an example) Eight minutes is the target you need to hit. You spend resources on hitting the eight minute target. So you have community responders, or FRUs instead of ambulances (because resources are limited). Responder goes to patient who needs urgent hospital treatment (let's say a AAA). There are no ambulances available because half the staff are on FRUs. You've 'succeeded' in the job because you got there in eight. The next free ambulance is sent to a different call because *that* needs to get there in eight. All the time the patient isn't getting any better because there is no-one available to take them to hospital. So the concentration on something that isn't clinically important has an effect on how the care is provided. This is my problem with it.
