London Ambulance Service

About LAS

The London Ambulance Service is the busiest ambulance Service in the UK. Around 8,000 staff and volunteers serve a diverse population of over 9 million Londoners.

From April 2022 – March 2023 we answered over 2 million 999 calls. From the time a call is received, we asses the needs of the caller to provide every single patient with the most appropriate response with the services we have available.

Our emergency medical dispatchers (EMDs), triage every call using Advanced Medical Priority Dispatch System (AMPDS). For more complex calls our EMDs are supported by the Clinical Support Desk (CSD). The CSD is staffed by clinical team leaders, mental health nurses, midwives and other medical professionals, who are able to triage complex calls using a modified Manchester Triage Tool.

At the London Ambulance Service, a range of responses can be delivered to every call for help; most minor cases can be dealt with over the telephone by the Clinical Hub, who may give patients  self-care advice or transfer them to an NHS 111 adviser. The LAS runs the NHS 111 Service in North East and South East London. 

Where a vehicle is dispatched to a patient, responses may include; a two person crewed ambulance, a solo rapid response car, a cycle response or Helicopter Emergency Medical Services  (HEMS).  LAS clinicians who deliver a face-to-face patient response include Emergency Ambulance Crew, Paramedics, Senior Paramedics and Advanced Paramedic Practitioners. Different types of clinicians provide different levels of care, treatment and procedures.

The LAS also employs specialist non-Paramedic clinicians, such as midwives, who can assist in the most complex maternity issues, and mental health nurses. In 2022/23 our Mental Health Joint Response Cars attended over 3,000 incidents across London.

These different response options enable the LAS to deliver appropriate care to all patients in an efficient manner.
