Battlefield medicine, also called field surgery and later combat casualty care, is the treatment of wounded combatants and non-combatants in or near an area of combat. Civilian medicine has been greatly advanced by procedures that were first developed to treat the wounds inflicted during combat. With the advent of advanced procedures and medical technology, even polytrauma can be survivable in modern wars. Battlefield medicine is a category of military medicine.

In 1989, the Commander of the Naval Special Warfare Command (NAVSPECWARCOM) established a research program to conduct studies on medical and physiologic issues. [17] The research concluded that extremity hemorrhage was a leading cause of preventable death in the battlefield. [17] At that time, proper care and treatment was not provided immediately which often resulted in death. This insight prompted a systematic reevaluation of all aspects of battlefield trauma care that was conducted from 1993 to 1996 as a joint effort by special operations medical personnel and the Uniformed Services University of the Health Sciences. [17] Through this 3-year research, the first version of the TCCC guidelines were created to train soldiers to provide effective intervention on the battlefield. The TCCC aims to combine good medicine with good small-unit tactics. [17] One very important aspect that the TCCC outlined was the use of tourniquets, initially there was a belief that the use of tourniquets led to the preventable loss of an extremity due to ischemia but after careful literature search the committee arrived at the conclusion that there was not enough information out there to confirm this claim. [17] The TCCC therefore outline the appropriate usage of tourniquets to provide effective first aid on the battlefield. [17]
After the TCCC article was published in 1996, the program undertook 4 parallel efforts during the next 5-year period. These efforts are as follows:

Over the past decade combat medicine has improved drastically. Everything has been given a complete overhaul from the training to the gear. In 2011, all enlisted military medical training for the U.S. Navy, Air Force, and Army were located under one command, the Medical Education and Training Campus (METC). After attending a basic medical course there (which is similar to a civilian EMT course), the students go on to advanced training in Tactical Combat Casualty Care. [18]
Tactical combat casualty care is becoming the standard of care for the tactical management of combat casualties within the Department of Defense and is the sole standard of care endorsed by both the American College of Surgeons and the National Association of EMT's for casualty management in tactical environments. [19]
Tactical combat casualty care is built around three definitive phases of casualty care:
Since "90% of combat deaths occur on the battlefield before the casualty ever reaches a medical treatment facility" (Col. Ron Bellamy) TCCC focuses training on major hemorrhaging and airway complications such as a tension-pneumothorax. This has driven the casualty fatality rate down to less than 9%. [22] [20]
Listed below are interventions that a TCCC provider may be expected to perform depending on the phase of TCCC they are at and their level of training. This list is not comprehensive and may be subject to change with future revisions in TCCC guidelines.
Hemorrhage control interventions include the use of extremity tourniquets, junctional tourniquets, trauma dressings, wound packing with compressed gauze and hemostatic dressings, and direct pressure. [23] Newer devices approved for use by the CoTCCC for hemorrhage control include the iTClamp and XStat. [24] Pharmacological options also include tranexamic acid, and hemostatic agents such as zeolite and chitosan. [23]
In managing a casualty's airway, a TCCC provider may position the casualty in the recovery position or utilize airway adjuncts such as nasopharyngeal airways, oropharyngeal airways, and supraglottic airways. [25] They may also utilize the jaw thrust and head-tilt/ chin-lift maneuver to open a casualty's airway. [25] Advanced TCCC providers may also perform endotracheal intubation and cricothyroidotomy. [25]
Respiratory management largely revolves around the use of chest seals, vented and unvented, and needle decompressions to manage tension pneumothoraxes. [25]
In circulation management a TCCC provider may obtain intravenous/ intraosseous access for the administration of fluids such as normal saline, lactated Ringer's solution, whole blood, and colloids and plasma substitutes for fluid resuscitation. [26] [27] This also provides a route for the administration of other drugs in accordance with the provider's scope of practice. [27]
Head injuries would indicate for cervical spine immobilization to the best of the provider's abilities if deemed appropriate in a given setting, or the use of devices such as a cervical collar. [28]
As trauma-induced hypothermia is a leading cause of battlefield deaths, a provider may also perform hypothermia prevention can be accomplished through the use of a Hypothermia Prevention and Management Kit or emergency blanket, the placement of a casualty on an insulated surface, and the removal of wet clothing from a casualty's body. [29]
Care under fire is care provided at the point of injury immediately upon wounding while the casualty and care provider remain under effective hostile fire. [30] The casualty should be encouraged to provide self-aid and remain engaged in the firefight if possible. [31] If unable to do so, the casualty should be encouraged to move behind cover or "play dead". [31] Due to the high risk of injury to the care-provider and limited resources at this phase, care provided to the casualty should be limited to controlling life-threatening hemorrhage with tourniquets and preventing airway obstruction by placing casualty in the recovery position. [32] The primary focus during care under fire should be winning the firefight to prevent further casualties and further wounding of existing casualties. [32]
Tactical field care phase begins when the casualty and care-provider are no longer under imminent threat of injury by hostile actions. [30] Though the level of danger is lessened, care-providers should exercise caution and maintain good situational awareness as the tactical situation may be fluid and subject to change. The tactical field care phase enables the provision of more comprehensive care according to care providers' levels of training, tactical considerations, and available resources. [30] Major tasks that are to be completed in the tactical field care phase include the rapid trauma survey, the triage of all casualties, and the transport decision. [30]
Tactical evacuation care refers to care provided when a casualty is being evacuated and en-route to higher levels of medical care. [30] Care providers at this phase are at even less risk of imminent harm as result of hostile actions. [30] Due to improved access to resources and the tactical situation, more advanced interventions can be provided to casualties such as endotracheal intubation. [30] Patient re-assessments and the addressing of issues that were not or were inadequately addressed previously are also major components of this phase. [30]
In tactical evacuation (TACEVAC), casualties are moved from a hostile environment to a safer and more secure location to receive advanced medical care. Tactical evacuation techniques use a combination of air, ground and water units to conduct the mission depending on the location of the incident and medical centres. Ground vehicle evacuations are more prevalent in urban locations that are in close proximity to medical facilities. [33] Requests for evacuation of casualties and pertinent information are typically communicated through 9-Line MEDEVAC and MIST reports. [34]
Tactical evaluation is an umbrella term that encompasses both medical evacuation (MEDEVAC) and casualty evacuation (CASEVAC). Medical evacuation platforms are typically not engaged in combat except in self-defence and defence of patients. [35] MEDEVAC takes place using special dedicated medical assets marked with a red cross. Casualty evacuation is through non-medical platforms and may include a Quick-Reaction force aided by air support. [33]
For aircraft involved TACEVAC situations there are many considerations that need to be accounted for. Firstly, the flying rules vary widely depending on the aircraft and units in play. [33] The list of determinants to create the TACEVAC strategy include the distances and altitudes involved, time of day, passenger capacity, hostile threat, availability of medical equipment/personnel, and icing conditions. [33] As mentioned TACEVAC is more advanced than TCCC, it also includes training to/for: [33]

There are three levels of tactical combat casualty care providers in the Canadian Armed Forces.
Every soldier receives a two-day combat first aid training course. The course focuses on treating hemorrhages, using tourniquets and applying dressings, and basic training for casualty management. [32]
A select number of soldiers are chosen to participate in an intense 2-week tactical combat casualty care course where soldiers are provided with additional training. [32] Overall, they are trained to work as medic extenders since they work under the direction of medics.
The tactical medicine (TACMED) course is offered exclusively to medics. The tactical medicine program provides training for advanced tactical combat casualty care and is the highest level of care provided by the Canadian Armed Forces in a battlefield setting. [32] Medics are trained to treat and manage patients using the MARCHE protocol. [32] The MARCHE protocol prioritizes potential preventable causes of death in warfare as follows:

Care under fire happens at the point of injury. According to tactical combat casualty care guidelines, the most effective way to reduce further morbidity and mortality is to return fire at enemy combatants by all personnel. [36] The priority is to continue the combat mission, gain fire superiority, and then treat casualties. [36] The only medical treatment rendered in care under fire is the application of direct pressure on massive bleeding. [36] Tactical combat casualty care recommends a tourniquet as the single most important treatment at the point of injury. [36] It is recommended during care under fire to quickly place tourniquets over clothing, high, and tight; the tourniquet should be reassessed when out of danger in the tactical field care phase. [36]
Tactical field care is considered to be the backbone of Tactical Combat Casualty Care and consists of care rendered by first responders or prehospital medical personnel while still in the tactical environment. [37] The acronyms MARCH and PAWS help personnel remember crucial treatment steps while under duress.
The MARCH acronym is used by personnel to remember the proper order of treatment for casualties.
Massive hemorrhage. The most potentially survivable cause of death is hemorrhage from extremity bleeds, however more than 90% of 4596 combat mortalities post September 11, 2001 died of hemorrhage associated injuries. [36] It is recommended to apply a Committee on Tactical Combat Casualty Care (CoTCCC) approved tourniquet for any life-threatening extremity hemorrhages. [36] Tourniquets during tactical field care should be placed under clothing 2 to 3 inches above the wound, with application time written on the tourniquet. [36]
Airway. Non-patent or closed airway is another survivable cause of death. Airway injuries typically occur due to inhalation burns or maxillofacial trauma. [36] If a person is conscious and speaking they have a patent open airway, while nasopharyngeal airway could benefit those who are unconscious and breathing. [36] However, unconscious casualties who are not breathing could require surgical cricothyroidotomy, as endotracheal intubation is highly difficult in tactical settings. [36]
Respirations. Tension pneumothorax (PTX) develops when air trapped in the chest cavity displaces functional lung tissue and puts pressure on the heart causing cardiac arrest. [36] Thus, open chest wounds must be sealed using a vented chest seal. [36] Tension pneumothorax should be decompressed using a needle chest decompression (NCD) with a 14 gauge, 3.25 inch needle with a catheter. [36] Ventilation and/or oxygenation should be supported as required. [36]
Circulation. It is more important to stem the flow of bleeding than to infuse fluids, and only casualties in shock or those who need intravenous (IV) medications should have IV access. [36] Signs of shock include unconsciousness or altered mental status, and/or abnormal radial pulse. [36] IV should be applied using an 18 gauge catheter and saline lock in tactical field care, secured by transparent would-dressing film. [36] Tranexamic acid (TXA) should be given as soon as possible to casualties in or at risk of hemorrhagic shock. [36] An intraosseous (IO) device could also be used for administering fluids if IV access is not feasible. [36]
Head injury/hypothermia. Secondary brain injury is worsened by hypotension (systolic blood pressure under 90 mmHg), hypoxia (peripheral capillary oxygen saturation under 90%), and hypothermia (whole body temperature below 95 Fahrenheit or 35 Celsius). [36] Medical personnel can use the Military Acute Concussion Evaluation (MACE), while non-medical personnel can use the alert, verbal, pain, unresponsive (AVPU) scale to identify traumatic brain injury. [36] The "lethal triad" is a combination of hypothermia, acidosis, and coagulopathy in trauma patients. [36] Since hypothermia can occur regardless of ambient temperature due to blood loss, the Hypothermia Prevention and Management Kit (HPMK) is recommended for all casualties. [36]
The PAWS acronym is used by personnel to remember additional casualty care items that should be addressed.
Pain. Proper management of pain reduces stress on a casualty's mind and body, and have reduced incidents of post-traumatic stress disorder (PTSD). [36] Pain management is shown to reduce harmful patient movement, improves compliance and cooperation, and allows for easier transport as well as improved health outcomes. [36]
Antibiotics. All battlefield wounds are considered contaminated, and thus any penetrating injury should receive antibiotics at the point of injury as well as in tactical field care. [36] The recommended parenteral antibiotics are 1g ertapenem or 2g cefotetan, which can treat multi drug-resistant bacteria. [36] if the casualty can tolerate oral fluids, 400mg moxifloxacin can be administered orally instead of ertapenem or cefotetan. [36]
Wounds. Assessing the casualty for additional wounds improves morbidity and mortality. First responders must address burns, open fractures, facial trauma, amputation dressings, and security of tourniquets. [36] Prior to movement, reassessment of wounds and interventions is very important. Casualties with penetrating trauma to the chest or abdomen should receive priority evacuation due to the possibility of internal hemorrhage. [36]
Splinting. Explosions (such as from improvised explosive device or land mines) that cause lower extremity traumatic amputation cause forces to move upward through the body, which may cause further bone disruption, hollow organ collapse, or internal bleeding. [36] Thus, first responders should use the Combat Ready Clamp (CRoC), the Junctional Emergency Treatment Tool (JETT), or the SAM Junctional Tourniquet to control junctional hemorrhage and stabilize the pelvis. [36] In cases of penetrative eye trauma, responders should first perform a rapid field test of visual acuity, then tape a rigid shield over the eye to prevent further damage, and also give 400mg oral moxifloxacin as soon as possible. [36] Pressure must never by applied to an eye suspected of penetrative injury. [36]
In order to evaluate the effectiveness of Tactical Combat Casualty Care, a study was conducted which analyzed US military casualties who died from an injury that occurred while they were deployed to Afghanistan or Iraq from October 2001 to June 2011. [38] Of the 4,596 casualties, 87% died in the pre-medical treatment facility, prior to receiving surgical care. [38] Of the casualties in the pre-medical treatment facility, 75.7% of the prehospital deaths were non-survivable, while 24.3% of deaths were potentially survivable. [38] Instantaneous non-survivable mortalities included physical dismemberment, catastrophic brain injury, and destructive cardiovascular injury. [38] Non-instantaneous non-survivable mortalities included severe traumatic brain injury, thoracic vascular injury, high spinal cord injury, and destructive abdominal pelvic injury. [38] These injuries are very difficult to treat given currently fielded medical therapies such as Tactical Combat Casualty Care. [38]
In terms of potentially survivable mortalities, 8.0% of mortalities were associated with airway obstruction. [38] Majority of mortalities (90.9%) which were classified as potentially survivable mortalities were attributed to hemorrhage, with 67.3% of the hemorrhage being truncal, 19.2% junctional, and 13.5% extremity. [38] During the study period, there were no effective protocols put in place to control junctional or truncal sources of hemorrhage in the battlefield, which suggests a gap in medical treatment capability. [38]
This study shows the majority of battlefield casualties which occur prior to receiving surgical care are non-survivable. However, of the casualties which are survivable, the majority of deaths can be attributed to hemorrhages. [38] Developing protocol which can control and temporize hemorrhage in the battlefield would improve the effectiveness of Tactical Combat Casualty Care, and decreases the number of casualties in the battlefield. [38]
Another study analyzed the effectiveness of tourniquets for hemorrhage control, which are used in Tactical Combat Casualty Care. [39] A four-year retrospective analysis showed that out of 91 soldiers who were treated with tourniquets, 78% of tourniquets were applied effectively. [39] The success rate for tourniquets applied to upper limbs was 94% while the success rate for tourniquets applied to lower limbs was 71%. [39] The difference between the success rates can be attributed to the tourniquets themselves, as in another study, tourniquets applied on healthy volunteers resulted in a much lower success rate for lower limbs in comparison to upper limbs. [39] Therefore, the tourniquets themselves can be redesigned to increase its effectiveness and improve Tactical Combat Casualty Care. [39]
A prospective study of all trauma patients treated at the Canadian-led Role 3 multinational medical unit (Role 3 MMU) established at Kandahar Airfield Base between February 7, 2006, to May 20, 2006, was conducted to examine how Tactical Combat Casualty Care interventions are delivered. [40] The study concluded that tourniquets are effective, but must be used appropriately. [40] The distinction between venous and arterial tourniquets must be reinforced in Tactical Combat Casualty Care training. [40] Tactical Combat Casualty Care courses must also train soldiers to remove tourniquets for the purposes of reassessing trauma after the patient and caregiver is no longer under enemy fire. [40] This is because the risks of iatrogenic ischemic injury of prolonged use of tourniquets outweigh the risks of increased blood loss. [40]
The study also identified technical errors in performing needle decompressions. [40] All needle decompressions were performed at least 2 cm (0.8 in) medial to the mid-clavicular line and well within the cardiac box. This may result in injury to the heart and surrounding vasculature. [40] Tactical Combat Casualty Care training must reinforce using landmarks when performing needle decompressions. [40] This is especially useful since soldiers may have to perform this procedure in poor lighting conditions. [40]
First aid is the first and immediate assistance given to any person with a medical emergency, with care provided to preserve life, prevent the condition from worsening, or to promote recovery until medical services arrive. First aid is generally performed by someone with basic medical or first response training. Mental health first aid is an extension of the concept of first aid to cover mental health, while psychological first aid is used as early treatment of people who are at risk for developing PTSD. Conflict first aid, focused on preservation and recovery of an individual's social or relationship well-being, is being piloted in Canada.
In medicine, triage is a process by which care providers such as medical professionals and those with first aid knowledge determine the order of priority for providing treatment to injured individuals and/or inform the rationing of limited supplies so that they go to those who can most benefit from it. Triage is usually relied upon when there are more injured individuals than available care providers, or when there are more injured individuals than supplies to treat them.
Mobile Army Surgical Hospitals (MASH) were U.S. Army field hospital units conceptualized in 1946 as replacements for the obsolete World War II-era Auxiliary Surgical Group hospital units. MASH units were in operation from the Korean War to the Gulf War before being phased out in the early 2000s, in favor of combat support hospitals.
The Expert Field Medical Badge (EFMB) is a United States Army special skills badge first created on June 18, 1965. This badge is the non-combat equivalent of the Combat Medical Badge (CMB) and is awarded to U.S. military personnel and North Atlantic Treaty Organization (NATO) military personnel who successfully complete a set of qualification tests, including both written and performance portions. The EFMB is known for its adherence to its testing standards and, as such, requires strict attention to detail from candidates in order to receive a "GO" on its combat testing lanes. The pass rate for FY 2017 was 7%, making the EFMB one of the most difficult and prestigious Army special skill badges to earn.
Casualty evacuation, also known as CASEVAC or by the callsign Dustoff or colloquially Dust Off, is a military term for the emergency patient evacuation of casualties from a combat zone. Casevac can be done by both ground and air. "DUSTOFF" is the callsign specific to U.S. Army Air Ambulance units. CASEVACs by air today are almost exclusively done by helicopter, a practice begun on a small scale toward the end of World War II; before that, STOL aircraft, such as the Fieseler Fi 156 or Piper J-3 were used.
A combat medic is responsible for providing emergency medical treatment at a point of wounding in a combat or training environment, as well as primary care and health protection and evacuation from a point of injury or illness. Additionally, medics may also be responsible for the creation, oversight, and execution of long-term patient care plans in consultation with or in the absence of a readily available doctor or advanced practice provider. Combat medics may be used in hospitals and clinics, where they have the opportunity to work in additional roles, such as operating medical and laboratory equipment and performing and assisting with procedures.
Advanced trauma life support (ATLS) is a training program for medical providers in the management of acute trauma cases, developed by the American College of Surgeons. Similar programs exist for immediate care providers such as paramedics. The program has been adopted worldwide in over 60 countries, sometimes under the name of Early Management of Severe Trauma, especially outside North America. Its goal is to teach a simplified and standardized approach to trauma patients. Originally designed for emergency situations where only one doctor and one nurse are present, ATLS is now widely accepted as the standard of care for initial assessment and treatment in trauma centers. The premise of the ATLS program is to treat the greatest threat to life first. It also advocates that the lack of a definitive diagnosis and a detailed history should not slow the application of indicated treatment for life-threatening injury, with the most time-critical interventions performed early.
A combat medical technician (CMT) is a soldier with a specialist trade within the Royal Army Medical Service of the British Army.
The term military medicine has a number of potential connotations. It may mean:
The Textbook of Military Medicine (TMM) is a series of volumes on military medicine published since 1989 by the Borden Institute, of the Office of The Surgeon General, of the United States Department of the Army. It constitutes a comprehensive, multi-volume treatise on the art and science of military medicine, as practiced by the United States armed forces. The books integrate lessons learned in past wars with current principles and practices of military medical doctrine.
Combat medics of the United States military may put themselves at greater risk than many other roles on the battlefield. In recent conflicts, the enemies faced by a professional army may not have respect for the laws of war and may actively target combat medics for the significant value they have in keeping the unit combat-effective. Since the non-combatant status granted to medics may not always be respected, modern combat medics carry weapons for personal defense and in most Western armies are virtually indistinguishable from regular infantrymen.
68W is the Military Occupational Specialty (MOS) for the United States Army's Combat Medic. 68Ws are primarily responsible for providing emergency medical treatment at point of wounding on the battlefield, limited primary care, and health protection and evacuation from a point of injury or illness. 68Ws are certified as Emergency Medical Technicians (EMT) through the National Registry of Emergency Medical Technicians (NREMT). However, 68Ws often have a scope of practice much wider than that of civilian EMTs. This specialty is open to males and females with minimum line scores of 107 GT and 101 ST on the Armed Services Vocational Aptitude Battery (ASVAB).
A wilderness medical emergency is a medical emergency that takes place in a wilderness or remote setting affinitive care. Such an emergency can require specialized skills, treatment techniques, and knowledge in order to manage the patient for an extended period of time before and during evacuation.
The 274th Forward Surgical Team (Airborne)—part of the 274th Forward Resuscitative and Surgical Detachment (Airborne)—is an airborne forward surgical team of the United States Army providing Level II care far forward on the battlefield. It was first constituted in 1944 and served in Europe during World War II. More recently it has been involved in relief operations following natural disasters and has undertaken several recent deployments to Iraq and Afghanistan. The 274th Forward Surgical Team was part of both the initial entry forces of Operation Enduring Freedom in 2001 and Operation Iraqi Freedom in 2003. Currently the unit falls under the command of the 28th Combat Support Hospital and is based at Fort Bragg, North Carolina.
Tactical Emergency medical support (TEMS) is out-of-hospital care given in hostile situations by specially trained practitioners. Tactical support provided through TEMS can be applied in either the civilian world, generally with special law enforcement teams such as SWAT and SERT, as well as with military special operations teams. Tactical EMS providers are paramedics, nurses, and physicians who are trained to provide life-saving care and, sometimes, transport in situations such as tactical police operations, active shooters, bombings, and natural disasters. Tactical medical providers (TMPs) provide care in high risk situations where there is an increased likelihood for law enforcement, civilian, or suspect casualties. TEMS units are also deployed in situations where traditional EMS or firefighters cannot respond. TMPs are specially trained and authorized to perform live-saving medical procedures in austere and often times unconventional environments. TMPs are also expected to be competent in weapons safety and marksmanship, small unit tactics, waterborne operations, urban search and rescue, and HAZMAT. TMPs also serve to train their respective teams in complex medical procedures that may be performed in their absence. TEMS providers are sometimes sworn police officers cross trained as paramedics, paramedics that are operators trained and integrated into the SWAT Team, or medical providers trained in tactical EMS who are then integrated into law enforcement or military units.
QuikClot is a brand of hemostatic wound dressing that contains an agent that promotes blood clotting. The brand is owned by Teleflex. It is primarily used by militaries and law enforcement to treat hemorrhaging from trauma.
Tactical Combat Casualty Care, formerly known as Self Aid Buddy Care, is a set of guidelines for trauma life support in prehospital combat medicine published by the United States Defense Health Agency. They are designed to reduce preventable deaths while maintaining operational success. The TCCC guidelines are routinely updated and published by the Committee on Tactical Combat Casualty Care (CoTCCC), which is part of the Defense Committees on Trauma (DCoT) division of the Defense Health Agency (DHA). TCCC was designed in the 1990s for the Special Operations Command medical community. Originally a joint Naval Special Warfare Command and Special Operations Medical Research & Development initiative, CoTCCC developed combat-appropriate and evidence-based trauma care based on injury patterns of previous conflicts. The original TCCC corpus was published in a Military Medicine supplement in 1996. TCCC has since become a Department of Defense (DoD) course, conducted by National Association of Emergency Medical Technicians.
Patriot Defence is a non-governmental organization (NGO) founded in May 2014 as a humanitarian initiative of the Ukrainian World Congress, for consistent development of tactical and emergency medical care in Ukraine. Its headquarters is in Kyiv, Ukraine, although various medical training programs are conducted all around the country.
Hasan Badre Alam is a trauma surgeon, surgeon-scientist, and a medical professor in the United States. He is the Loyal and Edith Davis Professor of Surgery, the Chairman of Department of Surgery at the Feinberg School of Medicine (FSM)/Northwestern University, and the Surgeon-in-Chief at Northwestern Memorial Hospital (NMH) in Chicago.
Prolonged field care refers to the specialized medical care provided to individuals who have sustained injuries or illnesses in situations where timely evacuation to a medical facility is delayed, challenging, or not feasible. This concept is applicable in various contexts, including military operations, wilderness emergencies, and disaster response scenarios. Definitions exhibit slight variation, but they convey the same fundamental meaning:
"Field medical care, applied beyond doctrinal planning time-lines"
"Field medical care that is applied beyond 'doctrinal planning time-lines' by a tactical medical practitioner in order to decrease patient mortality and morbidity."
"Prolonged care is provided to casualties if there is likely to be a delay in meeting medical planning timelines"
