Mapped: Fastest and slowest emergency ambulance responses by CCG

The map splits CCGs into four groups. The quartile with the fastest mean average response are coloured green, the second fastest in yellow, the third fastest in orange, and the slowest group in red.

The map shows that, although there are clusters of CCGs with slow or fast responses, performance is fairly mixed across England. There are also cases of CCGs in the fastest group neighbouring those in the slowest.

The data covers April to September last year.

Category two calls are also known as emergency calls. These cover a variety of conditions, including suspected stroke and heart attacks (except cardiac arrests), major burns and epileptic seizures, and account for well over half of ambulance responses.

All CCGs are served by one ambulance trust, with the exception of East Berkshire CCG, which is served by both South Central Ambulance Service Foundation Trust and South East Coast Ambulance Service FT. However, as the majority of its category two calls are handled by SCAS (14,431 compared with 318 at SECAmb), the mean average of 18.24 minutes for that trust has been used for the map.
