Yorkshire Ambulance Service
The Yorkshire Ambulance Service (YAS) is the NHS ambulance service covering most of Yorkshire in England formed on 1 July 2006 following the merges of the former West Yorkshire Metropolitan Ambulance Service (WYMAS), South Yorkshire Ambulance Service (SYAS) and Tees, East and North Yorkshire Ambulance service (TENYAS). It is one of ten Ambulance Trusts providing England with emergency medical services, free at the point of care and as part of the National Health Service it receives direct government funding for its role.
YAS covers the whole of the East Riding of Yorkshire (including Kingston upon Hull), South Yorkshire and West Yorkshire along with the majority of the ceremonial county of North Yorkshire (including the City of York). Excluded are Middlesbrough, Redcar and Cleveland and the southern part of Stockton-on-Tees which are all covered by the North East Ambulance Service.
Responses are controlled from two communication centres - one of which is located at YAS's headquarters at Wakefield 41 Business Park, located at the M1 motorway junction 41, north-west of Wakefield, covering West and South Yorkshire. The other communication centre is in Skelton on the outskirts of York, covering East and North Yorkshire. Until June 2008 there was a third communication centre in Rotherham which was inherited from the former South Yorkshire Ambulance Service but was found to be surplus to requirements.
YAS's activities are centred around the two core ones of Accident & Emergency (A&E) and Patient Transport Services (PTS) and is divided into five operational areas, known as Clinical Business Units (CBUs):
- North Yorkshire and Craven
- Leeds and Wakefield
- Bradford, Calderdale and Kirklees
- South Yorkshire
- Hull and East Riding.
The area which YAS covers includes the cities of Bradford, Hull, Leeds, Ripon, Sheffield, Wakefield and York, and the principal towns of Barnsley, Beverley, Doncaster, Harrogate, Huddersfield, Skipton and Scarborough. The region includes parts of the M1, A1(M), M18, M180, M62, M621 and M606 motorways and the Yorkshire Dales.
The current Chief Executive, David Whiting, joined YAS on 1 February 2011, becoming the third Chief Executive in five years. He was previously Chief Executive of Great Western Ambulance Service between April 2009 and January 2011. During his time at Great Western Ambulance Service, UNISON balloted its members for strike action following changes to terms and conditions for staff - particularly pay and rota arrangements. Whiting is a qualified paramedic with 28 years in the service before becoming Chief Executive Officer.
The former Chief Executives were Jayne Barnes OBE (1 July 2006 - 14 January 2008) and Martyn Pritchard (15 January 2008 - June 2010). Barnes emigrated to Australia to take up the post of Assistant Commissioner of Queensland Ambulance Service (South East region) and Pritchard left to take up a role at the Strategic Health Authority.
On 27 July 2010 Policy and Strategy Director David Forster was dismissed from his post after posting on social media website Facebook that: "The NHS has no shame in employing too many who are lazy, unproductive, obstinate, militant, aggressive at every turn and who couldn't secure a job anywhere outside the bloated public sector where mediocrity is shielded by weak and unprincipled HR policies."
Yorkshire Ambulance Service was formed on 1 July 2006 after the merger of the Tees, East and North Yorkshire Ambulance Service (TENYAS), South Yorkshire Ambulance Service (SYAS) and the West Yorkshire Metropolitan Ambulance Service (WYMAS) around the same time as many of the ambulance services in England merged with neighbouring services to become conterminous with the government regions.
West Yorkshire Metropolitan Ambulance Service
WYMAS was formed in 1974 covering the then new metropolitan county of West Yorkshire and the Craven district of North Yorkshire. It brought together some of the individual city ambulance services which existed across the area and in 1992, it became an NHS trust, providing 24-hour emergency and healthcare services to more than 2.1 million people across the region. WYMAS had 21 ambulance stations within its operating area.
Tees, East and North Yorkshire Ambulance Service
TENYAS was formed on 1 April 1999 as a merger of the former Cleveland, Humberside and North Yorkshire ambulance services and served the urban areas of Middlesbrough, York and Hull along with the rural areas of the Yorkshire Dales, Wolds, covering an area of approximately 4,500 square miles (12,000 km2). TENYAS had 37 ambulance stations within its operating area and resources were deployed from the two control rooms situated in Middlesbrough and York. The TENYAS operating area was broken up on 1 July 2006, with the former Cleveland area now covered by the North East Ambulance Service (NEAS). Humberside Ambulance Service had lost the A&E cover contract for the North Lincolnshire and North East Lincolnshire areas to Lincolnshire Ambulance Service before the existence of TENYAS.
South Yorkshire Ambulance Service
SYAS was formed in 1974 as the South Yorkshire Metropolitan Ambulance Service covering the then new metropolitan county of South Yorkshire. On 1 April 1992 it became an NHS Trust and served over 1.4 million people in an area of over 600 square miles (1,600 km2).
YAS operates just over 500 emergency vehicles which are a mix of Double Crewed Ambulance (DCAs), crewed by two members of staff (usually a qualified Paramedic or Emergency Medical Technician (EMT) working with an Emergency Care Assistant) and Rapid Response Vehicles (RRVs) which are crewed by a single paramedic, EMT or Emergency Care Practitioner.
YAS also operates over 460 Patient Transport Service (PTS) vehicles with around about 758 PTS staff to work them. 
YAS can deploy two MD 902 Explorer Helicopters of the Yorkshire Air Ambulance to emergencies and incidents across the service area, however the Air Ambulance Service is a charity and not an integral part of YAS - paramedics are provided by YAS and work on a rota with doctors who are voluntary members of the BASICS (British Association for Immediate Care) to offer additional medical skills.
YAS is a large organisation that have various roles to enable the service to operate, here are a few that are directly involved in the front line of the service 
- Community First Responder
- Emergency Operations Centre Call Handler
- Emergency Operations Centre Call Dispatcher
- Clinical Advisor
- Emergency Care Assistant (ECA)
- Emergency Medical Technician (EMT)
- Advanced Emergency Medical Technician (aEMT)
- Emergency Care Practitioners (ECPs)
- Paramedics aboard a Yorkshire Air Ambulance
- BASICS Doctors
Call for improvement
On 26 March 2010 the Care Quality Commission announced that YAS was consistently failing to meet national response time targets.
On 23 June 2010, the BBC announced that YAS call response was "England's worst". YAS was given until 31 October 2010 to meet targets adequately, which it stated it was doing, however, it was once again rated as the worst for response time in June 2011.
Performance problems continue into 2014, with only 69% of life-threatening incidents receiving a response within the arbitrary 8 minute target. This was below the requirement of 75%. 
University First Responders
Students from the Hull York Medical School (HYMS) and Community First Responders (CFR) from across Yorkshire received training from YAS at Hull Royal Infirmary. There are currently 63 medical students trained as Community First Responders in Hull and York who will respond to emergency calls alongside YAS within their community.
