SCAS 999 crew in hospital

Our 999 emergency service operates around the clock across Berkshire, Buckinghamshire, Hampshire and Oxfordshire.

Our road crews work with emergency call takers, dispatchers and clinicians working in our two clinical co-ordination centres to deal with 1.2million 999 calls each year.

Thanks to the skills, speed, professionalism and expertise of everyone working within the SCAS 999 service, today you are more likely to survive a major trauma than you were in the past.

Ready for the challenge

One of our key challenges has been keeping up with demand, particularly in emergency 999 calls where we have seen a steady year-on-year increase. This comes at a time of a national shortage of paramedics.

Our paramedic practitioners work in the community with additional skills such as being able to supply medication for a range of minor illnesses, provide advanced care for long term conditions, and manage a range of minor injuries at home. To support delivery of our key performance targets we have established a network of stand-by points, where vehicles wait until dispatched – we deploy rapid response vehicles (RRVs) and ambulances, each with highly-skilled staff trained in the use of the latest medical equipment.

We also respond to urgent calls from GPs and other health care professionals. As an ambulance service, we regularly work in close partnership with other blue light and emergency services in response to a wide range of incidents.

How does the service work?

It is simple. You use 999 BSL app or Website to make a call to 999, it will go to British Sign Language (BSL) interpreter first, who will appear on the screen. The BSL interpreter will then call the 999 operator through landline and will relay the conversation.
