Ambulance response categories

Information on how we categorise the emergency calls we respond to, and what the targets for each category are.

The way in which we categorise emergency calls changed in 2017, in line with new standards introduced across the country. 

This system of responding to patients was introduced by NHS England following the largest clinical ambulance trials in the world. 

Known as the Ambulance Response Programme, the changes aim to help all ambulance services reach the sickest patients more quickly, and end ‘hidden waits’ for lower category patients.

What this system means for our patients  

For calls that aren’t immediately life-threatening, call handlers have more time to understand the patient’s condition before sending an appropriate response or referring them to an alternative healthcare setting. 

Stroke and heart attack patients benefit because this enables us to send an ambulance crew that can treat them and take them to a specialist centre for further care, rather than a single responder who can begin treatment quickly but can’t transport them. 

We are expected to reach the most seriously ill patients (Category 1) in an average time of seven minutes. The clock only stops when the most appropriate response arrives on scene, rather than the first. 

This frees up more vehicles and staff to respond to other emergencies. 

 

 

Categories and response times 

Under this system, there are four categories of calls – please see the videos below about each: 

  • Category one: for life-threatening injuries and illnesses, specifically cardiac arrest. These will need to be responded to in an average time of seven minutes. 
  • Category two: for emergency calls, such as stroke patients. These will need to be responded to in an average time of 18 minutes. 
  • Category three: for urgent calls such as abdominal pains, and which will include patients to be treated in their own home. These will be responded to at least nine out of 10 times within 120 minutes. 
  • Category four: less urgent calls such as diarrhoea and vomiting and back pain. Some of these patients will be given advice over the telephone or referred to another service such as a GP or pharmacist. These less urgent calls will be responded to at least nine out of 10 times within 180 minutes.
