A field hospital is a temporary hospital or mobile medical unit that takes care of casualties on-site before they can be safely transported to more permanent facilities. This term was initially used in military medicine but it has also been used to describe alternate care sites used in disasters and other emergency situations.
A field hospital is a medical staff with a mobile medical kit and, often, a wide tent-like shelter (at times an inflatable structure in modern usage) so that it can be readily set up near the source of casualties. In an urban environment, the field hospital is often established in an easily accessible and highly visible building (such as , , and so on). In the case of an airborne structure, the mobile medical kit is often placed in a normalized container; the container itself is then used as shelter. A field hospital is generally larger than a temporary aid station but smaller than a permanent military hospital.
International humanitarian law such as the Geneva Conventions include prohibitions on attacking physician, , , or field hospitals buildings displaying a Red Cross, a Red Crescent or other emblem related to the International Red Cross and Red Crescent Movement; deliberately attacking or otherwise causing harm on these health facilities (especially during warfare or armed conflicts) may constitute a war crime.
Field hospitals are also prevalent in the event of and . The most recent pandemic, COVID-19, has led to the establishment of field hospitals in many parts of the world, especially in the developing world.
The PSM are stored in the hospitals where there are samus and .
The PMA is organized in four zones:
In case of really massive disaster, it is possible to have several PMA; the evacuation goes then not directly to a hospital, but to another big field hospital called "medical evacuation centre" ( centre médical d'évacuation, CME), to avoid the saturation of the hospitals.
In case of a red plan, the PMA is under the responsibility of a physician chosen by the director of medical rescue (DSM), and he is assisted by a firefighter officer chosen by the commander of rescue operation (COS). The firefighter officer has in charge the identification of the living casualties and of the secretaryship. The aim of the PMA is to sort and stabilize the casualties before their evacuation to a hospital.
A similar system can be set up as a preventive measure for some very big events (sport championship, cultural events, concert...), but managed by first aid associations. It is then called an "associative medical post" ( poste associatif médicalisé, PAM). (For smaller events, is simple first aid post, with only volunteer certified first responders and no medical staff, is set up.)
The civil defence military units ( Unité d'instruction et d'intervention de la sécurité civile, UIISC) have airborne field hospitals. The general system is called DICA ( détachement d'intervention de catastrophe aéroporté, i.e. airborne disaster unit), and is specialized in search-and-rescue and in emergency medicine; it can be enhanced by the Fast civil defence medical unit, called ESCRIM ( élément de sécurité civile rapide d'intervention médicale). The ESCRIM is a surgical unit ( detachement d'appui chirurgical) assisted by a medical assistance unit (DAMHo, détachement d'appui médical et d'hospitalisation); the later is specialized in pre- and post-operation care, and allows 48h of hospitalization. The UIISC also has a PMA (i.e. sort, stabilization and evacuation structure) when the hospital infrastructure of the country is sufficient.
During the COVID-19 pandemic the hospital was deployed to Hosea Kutako International Airport to aid the country's response.
In the United States Navy Bureau of Medicine and Surgery (BUMED), the counterpart to the Army's "field hospital" is known as an "Expeditionary Medical Facility" (EMF). The EMF is principally focused on support to Marines during expeditionary amphibious operations ashore, the Marine Corps having no medical personnel of their own and relying on the Navy for medical support. EMFs will also support Navy Construction Battalions (SeaBees) ashore. While the Navy has a small number of dedicated and larger combatant vessels such as aircraft carriers and large deck amphibious assault ships have robust medical facilities, the utility of those afloat platforms decreases the further inland that the Marines progress. A smaller and more mobile version of the EMF is the Expeditionary Medical Unit (EMU).
During the COVID-19 pandemic, the young physician Dr. Bidduth Barua established Chattogram Field Hospital which is the first post-liberation field hospital in Bangladesh to provide medical services to COVID-19 patients of Covid-19. On April 21 2020, the hospital officially started medical services.. A team of doctors, nurses and Young Volunteer are providing services in this hospital under the leadership of Dr. Bidduth Barua. Originally complete with Covid-19 patients In addition to providing free services, other patients are also being served here. Although fever, cold, sneeze and cough are predominant in patients, any patient can avail free services from here.
