London Ambulance Service
The London Ambulance Service (LAS) is a National Health Service trust that is responsible for answering and responding to medical emergencies in Greater London, with over 4,500 staff at its disposal. It is one of the busiest ambulance services in the world, and the busiest in the United Kingdom, serving more than 7 million people that live and work in London.
Once a 999 call has been received by the LAS Emergency Operations Centre, the London Ambulance Service will either resolve the call over the telephone or dispatch a front line or A&E support ambulance, fast response car (FRU), motorcycle response unit, cycle response unit or the Helicopter Emergency Medical Service (operating a helicopter, trauma response car and physician response unit), depending on the nature of the emergency. In exceptional cases, or where the service deems in necessary, specialist teams can be deployed from within the service, such as the Hazardous Area Response Team and Specialist Operations. These teams are specially trained and equipped to deal with incidents such as working at height or in confined spaces. 
It is one of 10 ambulance trusts in England providing emergency medical services, and is part of the National Health Service, receiving direct government funding for its role. There is no charge to patients for use of the service, as every person in England has the right to the attendance of an ambulance in an emergency.
The LAS responds to over 1.5 million calls for assistance every year. All 999 calls from the public are answered at the Emergency Operations Centre (EOC) in Waterloo, which then dispatches the appropriate resources. To assist, the service's command and control system is linked electronically with the equivalent system for London's Metropolitan Police. This means that police updates regarding specific jobs will be updated directly on the computer-aided dispatch (CAD) log, to be viewed by the EOC and the resources allocated to the job.
During World War II, the London Auxiliary Ambulance Service was operated by over 10,000 auxiliaries, mainly women, from all walks of life. They ran services from 139 Auxiliary Stations across London. A plaque at one of the last to close, Station 39 in Weymouth Mews, near Portland Place, commemorates their wartime service. 
In 1948 the National Health Service Act (1946) made it a requirement for ambulances to be available for anyone who needed them.
The present-day London Ambulance Service was formed in 1965 by the amalgamation of nine existing services in London and in 1974, after a reorganisation of the NHS, the LAS was transferred from the control of local government to the South West Thames Regional Health Authority.
As an NHS Trust, the LAS has a Trust Board consisting of a chief executive, a chairman, five LAS executive directors and five external non-executive directors.
The chief executive and Chief Ambulance Officer have responsibility for oversight of seven directorates:
- Accident and emergency (A&E)
- Finance and business
- Human resources
- Patient transport services (PTS)
Operations are directed from service headquarters in Waterloo Road which houses the Emergency Operations Centre (EOC) for despatching emergency service vehicles and also coordinates major incident responses or from a back-up control room in east London should the main control room become compromised. Special events in London are co-ordinated from the Service's event control room, also located in east London, or from the Metropolitan Police control room as appropriate.
During mass casualty incidents, the command structure works on three (or four) levels: gold, silver and bronze.
- Platinum control: government level command (COBR);
- Gold control: strategic command, located in a situation room close to the main Emergency Operations Centre (EOC) and managing not only the incident but ensuring that normal service function continues with reduced resources.
- Silver control: tactical command, from a designated point in the vicinity of the incident(s);
- Bronze control: on-site operational level organising triage for casualties.
- Ambulance attendant (PTS)
- A&E support
- Emergency Medical Dispatcher (EMD1, EMD2, EMD3, Allocator)
- Clinical telephone advisor
- Emergency medical technician (EMT1, EMT2, EMT3, EMT4)
- Student paramedic levels 1, 2, 3, 4
- Apprentice Paramedic year 0, 1, 2, 3, 4
- Emergency Care Practitioner (ECP) (No longer within the service.)
- HEMS Paramedic
- Hazardous Area Response Team (HART) operative
Volunteers supporting the London Ambulance Service
Volunteers make up a small but significant proportion of front line ambulance staff that respond to emergency calls in London. Voluntary responders vary in skill level, but their principle purpose remains the same. That is to attend medical emergencies as quickly as possible to improve the patient's chance of survival, saving lives which may have been lost without the additional resources being available to the ambulance service. Importantly, the deployment of any voluntary responder will not replace the automatic allocation of a regular front line ambulance.
There are two principle roles for volunteers within the London Ambulance Service. These roles include:
- Emergency Responder - clinically trained volunteers who operate in marked response cars with blue lights and wear full service uniform, typically working double crewed and doing shifts of up to 10 hours day and night.
- Community responder - defibrillator trained St John Ambulance volunteers attending on call from their homes and responding to 999 calls in their own car without blue lights alongside ambulances.
London Ambulance Service volunteers are supported by a charity called London Ambulance Service Voluntary Responder Group (registered charity no.1061191), providing logistical and financial assistance to keep volunteers operational. The London Ambulance Service can also call upon auxiliary aid from external voluntary organisations such as St John Ambulance and the British Red Cross, as demonstrated on 7/7.
The LAS operates around 900 ambulances. In addition it can deploy around 100 rapid-response units in various cars, motorcycles, or bicycles. Although not a part of the LAS, the London Air Ambulance can also be deployed by, and for, the LAS from its base at the Royal London Hospital in Whitechapel.
As well as accidents and emergencies, the LAS operates a 195-vehicle patient transport service (PTS). Previously a centrally funded service, this element of the LAS is now subject to an open market and is required to tender for work from primary care trusts (PCTs) and other NHS bodies. As well as being contracted by a number of London hospitals and PCTs to take patients to and from their pre-arranged hospital or clinic appointments, the PTS responds to ad-hoc journey requests and provides specialist transfer facilities.
The LAS plays a significant role whenever an incident causes mass casualties in London. Examples include:
- 7 July 2005 suicide attacks: Four suicide bombings across London. Voluntary aid services needed to assist the LAS due to scale of the attacks.
- Paddington train crash: Two trains collided a short distance outside of Paddington station, killing 31 people
- Cannon Street rail crash: Two people were killed and over 500 injured
- Marchioness disaster: A pleasure boat, Marchioness, was in collision with a dredger; 51 people died
- Clapham Junction train crash: 35 people were killed and 69 seriously injured
- King's Cross fire: 31 people died in a major fire in the Underground station
- Moorgate tube crash: the train driver and 42 passengers were killed
- Provisional IRA bombing campaign: a list of these and other bombings in London to which the LAS responded can be found here.
Due to an increase in demand, the LAS has used private ambulance companies, including some charities, to provide additional everyday operational cover. This is largely to ensure set response targets are met and so that the level of resources available to the service stays at a safe level. The future of private ambulances within the LAS is unclear. IN March 2014 operational difficulties were reported at Hillingdon Hospital because the private ambulances did not appear on the A&E hospital alert system.
Difficulties and criticisms
In 2000, the LAS faced funding difficulties and an increase in the volume of 999 calls, and it was criticised for poor performance in its response times. The service was sued for negligence in the case of Kent v Griffiths. The chief executive at the time, Michael Honey, left his post after talks with other members of LAS management.
In 2010 the service lost its funding for the emergency care practitioner (ECP) role and existing ECPs were told they must change to a different role within the service, or leave.
A fire in the basement of its Waterloo base in October 2010 caused the LAS to relocate the EOC to the back-up control room in east London due to an interruption to the building's power supply. The service took the step of urging the public to find other means of transport to hospital for anyone suffering non-life-threatening injuries.
Concerns were raised in internal LAS documents over the performance of radios and communication equipment used in the emergency operations after the 7/7 attacks. Again, the sheer volume of emergency calls received made radio communications difficult and put pressure on staff in the ambulance control room. Staff were also hampered in their use of mobile phones as the mobile phone networks were temporarily brought down during the day. In July 2009 the new radio system recommended after the bombings was rolled out.
Despite the changes after 7/7, the LAS was criticised in 2010 for failures to provide fully working radios to its frontline staff. Health and safety inspections found that some radios failed during heavy rain and staff sometimes had to do without. Crews also raised concerns that the panic buttons on their radios did not work properly.
In 1974, the LAS commissioned a computer-aided despatch system that remained unused for 13 years because union members refused to operate it. A replacement system failed acceptance tests in 1990 and a further replacement system was designed and ordered. On 26 October 1992 the LAS started to use the new computer-assisted dispatch (CAD) system, known as LASCAD. Poorly designed and implemented, its introduction led to significant delays in the assigning of ambulances, with anecdotal reports of 11-hour waits. A subsequent enquiry found no evidence to support union claims that up to 30 people may have died as a result of the crash. The crash coincided with hundreds of control room exceptions messages related to alerts that crews responding to emergencies had not reported mobile, and the ambulance had not moved 50 metres within 3 minutes of despatch. The then-chief executive, John Wilby, resigned shortly afterwards. This failure is often cited in case studies of poor engineering management.
During its implementation it developed technical problems and was replaced by a pen-and-paper method for several hours until a decision was taken to revert to the previous system, CTAK, in the early hours of 9 June. It was later announced that a review of the difficulties experienced would be undertaken.
A second attempt at implementing CommandPoint was due to take place on 28 March 2012. The trust was considering terminating its contract with Northrop Grumman if the re-attempt to go live with the new system failed.[needs update]
