A review of the 'amber' category of ambulance calls is underway.
Since October 2015, the Welsh Ambulance Service have operated a traffic light system of call categorisation. Each call is given a colour: red for life threatening, amber for serious bit not life threatening and green for less serious incidents. Under this response model, only red calls have a target time.
Ever since the model came into force, the service has hit its target of getting to 65% of 'red' calls within eight minutes.
The latest monthly response time figures continue this trend, but only 5.5% of the total calls were graded as 'red'. Even so, 5.5% is still the highest since the new model was introduced.
The planned review of the 'amber' call category is being carried out by a team headed by the Chief Ambulance Services Commissioner, Stephen Harrhy.
The review is expected to complete by September 2018.
