Throughout the evolution of paramedic care, there has been an ongoing association with military conflict. One of the first indications of a formal process for managing injured people dates from the Imperial Legions of Rome, where aging Centurions, no longer able to fight, were given the task of organizing the removal of the wounded from the battlefield and providing some form of care. Such individuals, although not physicians, were probably among the world's earliest surgeons by default, being required to suture wounds and complete amputations. A similar situation existed in the Crusades, with the Knights Hospitallers of the Order of St. John of Jerusalem filling a similar function; this organisation continued, and evolved into what is now known throughout the Commonwealth of Nations as the St. John Ambulance.
Early ambulance services
While civilian communities had organized ways to deal with the care and transportation of the sick and dying as far back as the bubonic plague in London between 1598 and 1665, such arrangements were typically temporary. In time, however, these arrangements began to formalize and become permanent. During the American Civil War, Jonathan Letterman devised a system of mobile field hospitals employing the first uses of the principles of triage. After returning home, some veterans began to attempt to apply what had they had seen on the battlefield to their own communities, and commenced the creation of volunteer life-saving squads and ambulance corps.

These early developments in formalised ambulance services were decided at local levels, and this led to services being provided by diverse operators such as the local hospital, police, fire brigade, or even funeral directors who often possessed the only local transport allowing a passenger to lie down. In most cases these ambulances were operated by drivers and attendants with little or no medical training, and it was some time before formal training began to appear in some units. An early example was the members of the Toronto Police Ambulance Service receiving a mandatory five days of training from St. John as early as 1889.[4]
Prior to World War I motorized ambulances started to be developed, but once they proved their effectiveness on the battlefield during the war the concept spread rapidly to civilian systems. In terms of advanced skills, once again the military led the way. During World War II and the Korean War battlefield medics administered painkilling narcotics by injection in emergency situations, and pharmacists' mates on warships were permitted to do even more without the guidance of a physician. The Korean War also marked the first widespread use of helicopters to evacuate the wounded from forward positions to medical units, leading to the rise of the term "medivac". These innovations would not find their way into the civilian sphere for nearly twenty more years.
Pre-hospital emergency care
By the early 1960s experiments in improving care had begun in some civilian centres. One early experiment involved the provision of pre-hospital cardiac care by physicians in Belfast, Northern Ireland, in 1966.[5] This was repeated in Toronto, Canada in 1968 using a single ambulance called Cardiac One, which was staffed by a regular ambulance crew, along with a hospital intern to perform the advanced procedures. While both of these experiments had certain levels of success, the technology had not yet reached a sufficiently advanced level to be fully effective; for example, the Toronto portable defibrillator and heart monitor was powered by lead-acid car batteries, and weighed around 45 kilograms (99 lb).

In 1966 a report called Accidental Death and Disability: The Neglected Disease of Modern Society—commonly known as The White Paper—was published in the United States. This paper presented data showing that soldiers who were seriously wounded on the battlefields during the Vietnam War had a better survival rate than individuals who were seriously injured in motor vehicle accidents on California's freeways.[6] Key factors allowing the victim to survive the journey to definitive care such as a hospital were stated to be comprehensive trauma care, rapid transport to designated trauma facilities, and the presence of medical corpsman who were trained to perform certain critical advanced medical procedures such as fluid replacement and airway management.
As a result of the The White Paper the Federal government moved to develop minimum standards for ambulance attendant training, ambulance equipment and vehicle design. These new standards were incorporated into Federal Highway Safety legislation and the state were advised to either adopt these standards into state laws or risk a reduction in Federal highway safety fundings. The "White Paper" also prompted the inception of of a number of emergency medical service (EMS)pilot units across the US including paramedic programs. The success of these units led to a rapid transition to make them fully operational, with the first paramedic program being in Miami, Florida.
New York City's Saint Vincent's Hospital developed America's first Mobile Coronary Care Unit (MCCU) under the medical direction of William Grace, MD and was based on Dr. Frank Pantridge's Belfast, Northern Ireland MCCU project. In 1967 Eugene Nagle, MD and Jim Hirschmann, MD helped pioneer America's first EKG telemetry transmission to a hospital and then in 1968, a functional paramedic program in conjunction with the City of Miami Fire Department. In 1969. the City of Columbus Fire Services joined together with the Ohio State University Medical Center and developed the "HEARTMOBILE" paramedic program under the medical direction of James Warren, MD and Richard Lewis, MD. In 1969. the Haywood County (NC) Volunteer Rescue Squad developed a paramedic program under the medical direction of Ralph Fleicher, MD. In 1969, the initial Los Angeles paramedic training program was instituted in conjunction with Harbor General Hospital under the medical direction of Michael Criley, MD and James Lewis, MD. In 1969, the Seattle "Medic 1" paramedic program was developed in conjunction with the Harborview Medical Center under the medical direction of Leonard, Cobb. The Marietta (GA) initial paramedic project was instituted in the Fall of 1970 in conjunction with Kennestone Hospital and Metro Ambulance Service, Inc. under the medical direction of Luther Fortson, MD. The Los Angeles county and city established paramedic programs following the passage of The Wedworth-Townsend Act in 1970. This was followed by other cities and states passing their own paramedic bills, leading to the formation of services across the US. Many other countries also followed suit, with paramedic units quickly being formed around the world.
In the military, however, the required telemetry and miniaturization technologies were more advanced, particularly due to initiatives such as the space program, but it would take several more years before these technologies drifted through to civilian applications. In North America, physicians were judged to be too expensive to be used in the pre-hospital setting, although such initiatives were implemented, and sometimes still operate, in European countries and Latin America.
Public notability
While doing background research at Los Angeles' UCLA Harbor Medical Center for a proposed new show about doctors, television producer Robert A. Cinader, working for Jack Webb, happened to encounter "firemen who spoke like doctors and worked with them".[citation needed] This concept developed into the television series Emergency!, which ran from 1972 to 1979, portraying the exploits of this new profession called paramedics. The show gained popularity with emergency services personnel, the medical community, and the general public. When the show first aired in 1972, there were just six paramedic units operating in three pilot programs in the whole of the US, and the term paramedic was essentially unknown. By the time the program ended in 1979, there were paramedics operating in all fifty states. The show's technical advisor, James O. Page, was a pioneer of paramedicine and responsible for the UCLA paramedic program; he would go on to help establish paramedic programs throughout the US, and was the founding publisher of the Journal of Emergency Medical Services (JEMS). The JEMS magazine creation resulted from Page's previous purchase of the "PARAMEDICS International" magazine.
Evolution and growth
Throughout the 1970s and 80s, the paramedic field continued to evolve, with a shift in emphasis from patient transport to treatment both on scene and en-route to hospitals. This led to some services changing their descriptions from "ambulance services" to "emergency medical services".

The training, knowledge-base, and skill sets of both paramedics and emergency medical technicians (EMTs) were typically determined by local medical directors, what it was felt the community needed, and what was affordable. There were also large differences between localities in the amount and type of training required, and how it would be provided. This ranged from in-service training in local systems, through community colleges, and up to university level education. This emphasis on increasing qualifications has followed the progression of other health professions such as nursing, which also progressed from on the job training to university level qualifications.
The variations in educational approaches and standards required for paramedics has led to large differences in the required qualifications between locations—both within individual countries and from country to country. This has led to many countries passing laws to protect the title of "paramedic" (or its local equivalent) from use by anyone except those qualified and experienced to a defined standard. This usually means that paramedics must be registered with the appropriate body in their country, for example all paramedics in the United Kingdom must by registered with the Health Professions Council in order to call themselves a paramedic. In the United States, a similar system is operated by the National Registry of Emergency Medical Technicians (NREMT), although this is only accepted by forty of the fifty states.
As paramedicine has evolved a great deal of both the curriculum and skill set has existed in a state of flux. Requirements often originated and evolved at the local level, and were based upon the preferences of physician advisers and medical directors. Recommended treatments would change regularly, often changing more like a fashion than a scientific discipline. Associated technologies also rapidly evolved and changed, with medical equipment manufacturers having to adapt equipment that worked adequately the hospital environment to be able to cope with the less controlled pre-hospital environment.
Physicians began to take more interest in paramedics from a research perspective as well. By about 1990, the fluctuating trends began to diminish, being replaced by outcomes-based research. This research then drove further evolution of the practice of both paramedics and the emergency physicians who oversaw their work, with changes to procedures and protocols occurring only after significant research demonstrated their need and effectiveness. Such changes affected everything from simple procedures, such as CPR, to changes in drug protocols. As the profession grew, some paramedics went on to become not just research participants, but researchers in their own right, with their own projects and journal publications.
Changes in procedures also included the manner in which the work of paramedics was overseen and managed. In the early days medical control and oversight was direct and immediate, with paramedics calling into a local hospital and receiving orders for every individual procedure or drug. While this still occurs in some jurisdictions, it has become increasingly rare, with physicians building an increasing confidence and trust in the work of paramedics. Day-to-day operations largely moved from direct and immediate medical control to pre-written protocols or standing orders, with the paramedic typically seeking advice after the options in the standing orders had been exhausted.
