teer basis, receiving no monetary compensation for their services (i.e. Volunteer Rescue Squad / Volunteer Fire Department and community response units).
In England, paramedics are typically employed by ambulance services, as a part of the National Health Service Trust system. An NHS Trust is, in effect, a type of public sector corporation, and most NHS health services, including both primary care and hospitals, are organized in this fashion. Service organization occurs regionally, with Ambulance Service Trusts typically covering several local Counties, and with 12 such Trusts currently providing coverage for the entire country. Ambulance Service in Wales operates on a similar system, while the Scottish Ambulance Service and Northern Ireland Ambulance Service are single entities provided by the Health Departments of their respective federal governments. Additional coverage, particularly for special events, may be provided by Voluntary Ambulance Services, including the British Red Cross and St. John Ambulance, or by private companies, but neither of these typically uses fully qualified paramedics.
In Canada, paramedics are employed almost exclusively by publicly operated EMS systems. The manner in which such systems are organized and funded varies somewhat from province to province. The British Columbia Ambulance Service is organized as a branch of the provincial government, with that government providing services directly through a branch of the Ministry of Health. In Ontario, the provision of EMS has been allocated to Upper-tier municipalities (like U.S. Counties). Each of these provides its own EMS, and is free to operate the service directly as third service or, in rare cases, as a branch of the fire department, or to contract those services to a private business entity or a local hospital. In all of these cases, the provincial government accredits the services, and provides operating standards and some funding. In the Maritime Provinces the provincial governments have entered into long term contractual arrangements with a single private company for the operation of their EMS systems. Other Canadian provinces use still other approaches to the provision of service and the operating environment in which paramedics will work.
In Australia, paramedics work exclusively for the State Ambulance Service, including Ambulance Victoria service (http://www.ambulance.vic.gov.au/), among others. Public ambulance services in Australia are exclusively third-service option. These services are operated directly by each of the states and territories. A separate service is provided for the Australian Capitol Territory. Unlike the U.S., Australian paramedics are not typically employed in hospitals or the fire brigade. While there are a handful of private ambulance companies operating in Australia, these do not typically provide what would normally be described as 'paramedic' levels of service.
In some centers, some paramedics have begun to specialize their practice. This specialization frequently is to some degree tied to the environment in which the paramedic will work. One of the earliest examples of this involved aviation medicine, and the use of helicopters. Another was the transfer of critical care patients between facilities. While some jurisdictions still use physicians, nurses and technicians for this purpose, increasingly, this role falls to specially-trained, very senior and experienced paramedics, who perform this role as their primary job function. Other areas of specialization include such roles as tactical paramedics working in police tactical units, marine paramedics, hazardous materials (Hazmat)teams, and Heavy Urban Search and Rescue. Still others work in physical isolation, on offshore oil platforms, oil and mineral exploration teams, and in the military. In some cases, one can even find paramedics working on cruise ships! A new and evolving role for paramedics involves the expansion of their practice into the provision of relatively simple primary health care and assessment services.
