Emergency medical services
type of emergency service dedicated to providing out-of-hospital acute medical care and transport to definitive care
Emergency medical services (EMS), also known as ambulance services, pre-hospital care, or paramedic services, are emergency services that provide urgent pre-hospital treatment and stabilisation for serious illness and injuries and transport to definitive care. They may also be known as a first aid squad, FAST squad, emergency squad, ambulance squad, ambulance corps, life squad or by other initialisms such as EMAS or EMARS.
In most places, EMS can be summoned by members of the public (as well as medical facilities, other emergency services, businesses and authorities) via an emergency telephone number which puts them in contact with a dispatching centre, which will then dispatch suitable resources for the call. Ambulances are the primary vehicles for delivering EMS, though squad cars, motorcycles, aircraft, boats, fire apparatus, and others may be used. EMS agencies may also operate a non-emergency patient transport service, and some have rescue squads to provide technical rescue or search and rescue services.
When EMS is dispatched, they will initiate medical care upon arrival on scene. If it is deemed necessary or a patient requests transport, the unit is then tasked with transferring the patient to the next point of care, typically an emergency department of a hospital. Historically, ambulances only transported patients to care, and this remains the case in parts of the developing world. The term "emergency medical service" was popularised when these services began to emphasise emergency treatment at the scene. In some countries, a substantial portion of EMS calls do not result in a patient being taken to hospital.
Training and qualification levels for members and employees of emergency medical services vary widely throughout the world.
This brief starts where responsible research should: with the source description of “Emergency medical services” as type of emergency service dedicated to providing out-of-hospital acute medical care and transport to definitive care.

Why this record matters
The subject matters to the general reference register because the source frames it as type of emergency service dedicated to providing out-of-hospital acute medical care and transport to definitive care. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 12, 2026. The linked authority identifier is Q860447. The Library of Congress control number is sh85042747. 1 of 2 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
