The number of compliments have risen by 6.7 per cent and they dwarf the number of complaints.

In 2013/14, the trust received 972 letters, emails, tweets and Facebook posts praising the work of staff. The figure is up from 911 the previous year.

The ambulance service dealt with 967,145 emergency calls last year and 649,332 non-emergency journeys.

Director of Nursing and Quality, Sue Green, said: “Whilst one complaint is one too many, the figure is very small compared to the number of people the Trust helps.

“Whilst we do not want to receive complaints, we very much see it as a positive. The more we are able to interact with the public and learn from their views, the better the service will become.

“We have made numerous appeals for people to use the 999 service wisely but some people do still call us with less serious conditions.

“In many cases it simply isn’t appropriate to send an ambulance to them so we get an experienced paramedic to speak to the patient and provide advice over the phone or refer them to a minor injuries unit or their GP.

“Some patients are unhappy with this resolution, which we accept. However, for a service that is set up to deal with truly life threatening conditions and injuries such as cardiac arrests and strokes, it has to be right that we prioritise our resources in dealing with these time critical cases first.”
