Helicopter Emergency Medical Services During Coronavirus Disease 2019 in Nepal.

Virtually every country in the world has been affected by coronavirus disease 2019 (COVID-19). Nepal is a landlocked country located in Southern Asia. Nepal's population has suffered greatly due to a shortage of critical care facilities, resources, and trained personnel. For appropriate care, patients need access to hospitals mostly in the centrally located capital city of Kathmandu. Unfortunately, Nepal's resources and personnel dedicated to transferring COVID-19 patients are scarce. Road and traffic infrastructure problems and mountainous terrain prevent ground ambulances from performing effectively. This, in addition to Nepal lacking national standards for prehospital care, create great challenges for transferring patients via ground emergency medical services. The concept of helicopter emergency medical services (HEMS) began in 2013 in Nepal. Presently, 3 hospitals, Nepal Mediciti Hospital, Hospital for Advanced Medicine and Surgery (HAMS), and Grande International Hospital, coordinate with private helicopter companies to run proper HEMS. One entity, Simrik Air, has dedicated 2 Airbus H125/AS350 helicopters for the sole purpose of transferring COVID-19 patients. HEMS effectiveness is expanding in Nepal, but much remains to be accomplished.

Operational experience of the Dutch helicopter emergency medical services (HEMS) during the initial phase of the COVID-19 pandemic: jeopardy on the prehospital care system?

PURPOSE: The SARS-CoV-2 virus has disrupted global and local medical supply chains. To combat the spread of the virus and prevent an uncontrolled outbreak with limited resources, national lockdown protocols have taken effect in the Netherlands since March 13th, 2020. The aim of this study was to describe the incidence, type and characteristics of HEMS and HEMS-ambulance 'Lifeliner 1' dispatches during the initial phase of the COVID-19 pandemic compared to the same period one year prior. METHODS: A retrospective review of all HEMS and HEMS-ambulance 'Lifeliner 1' dispatches was performed from the start of Dutch nationwide lockdown orders from March 13th until May 13th, 2020 and the corresponding period one year prior. Dispatch-, operational-, patient-, injury-, and on-site treatment characteristics were extracted for analysis. In addition, the rate of COVID-19 positively tested HEMS personnel and the time physicians were unable to take call was described. RESULTS: During the initial phase of the COVID-19 pandemic, the HEMS and HEMS-ambulance was requested in 528 cases. One year prior, a total of 620 requests were received. The HEMS (helicopter and ambulance) was cancelled after deployment in 56.4% of the COVID-19 cohort and 50.7% of the historical cohort (P = 0.05). Incident location type did not differ between the two cohorts, specifically, there was no significant difference in the number of injuries that occurred at home in pandemic versus non-pandemic circumstances. Besides a decrease in the number of falls, the distribution of mechanisms of injury remained similar during the COVID-19 study period. There was no difference in self-inflicted injuries observed. Prehospital interventions remained similar during the COVID-19 pandemic compared to one year prior. Specifically, prehospital intubation did not differ between the two cohorts. The rate of COVID-19 positively tested HEMS personnel was 23.1%. Physicians who tested positive were unable to take call for a mean of 25 days (range 8-53). CONCLUSION: A decrease in the number of deployments and increase in the number of cancelled missions was observed during the COVID-19 study period. No major differences in operational- and injury characteristics were found for HEMS and HEMS-ambulance dispatches between the initial phase of the COVID-19 pandemic in the Netherlands and the same period one year prior. These findings highlight the importance of continued operability of the HEMS, even during pandemic circumstances. LEVEL OF EVIDENCE: III, retrospective comparative study.

The first seven years of nationally organized helicopter emergency medical services in Finland - the data from quality registry.

BACKGROUND: Helicopter Emergency Medical Services (HEMS) play an important role in prehospital care of the critically ill. Differences in funding, crew composition, dispatch criteria and mission profile make comparison between systems challenging. Several systems incorporate databases for quality control, performance evaluation and scientific purposes. FinnHEMS database was incorporated for such purposes following the national organization of HEMS in Finland 2012. The aims of this study are to describe information recorded in the database, data collection, and operational characteristics of Finnish HEMS during 2012-2018. METHODS: All dispatches of the six Finnish HEMS units recorded in the national database from 2012 to 2018 were included in this observational registry study. Five of the units are physician staffed, and all are on call 24/7. The database follows a template for uniform reporting in physician staffed pre-hospital services, exceeding the recommended variables of relevant guidelines. RESULTS: The study included 100,482 dispatches, resulting in 33,844 (34%) patient contacts. Variables were recorded with little or no missing data. A total of 16,045 patients (16%) were escorted by HEMS to hospital, of which 2239 (2%) by helicopter. Of encountered patients 4195 (4%) were declared deceased on scene. The number of denied or cancelled dispatches was 66,638 (66%). The majority of patients were male (21,185, 63%), and the median age was 57.7 years. The median American Society of Anesthesiologists Physical Scale classification was 2 and Eastern Cooperative Oncology Group performance class 0. The most common reason for response was trauma representing 26% (8897) of the patients, followed by out-of-hospital cardiac arrest 20% (6900), acute neurological reason excluding stroke 13% (4366) and intoxication and related psychiatric conditions 10% (3318). Blunt trauma (86%, 7653) predominated in the trauma classification. CONCLUSIONS: Gathering detailed and comprehensive data nationally on all HEMS missions is feasible. A national database provides valuable insights into where the operation of HEMS could be improved. We observed a high number of cancelled or denied missions and a low percentage of patients transported by helicopter. The medical problem of encountered patients also differs from comparable systems.

Military Nursing in "Operation Return to Brazil": aeromedical evacuation in the coronavirus pandemic / Enfermería militar en la "Operación Regreso a Brasil": evacuación aeromédica en la pandemia de coronavirus / Enfermagem Militar na "Operação Regresso ao Brasil": evacuação aeromédica na pandemia do coronavirus

ABSTRACT Objective: to describe the experience of military nursing in "Operation Return to Brazil" in an aeromedical evacuation. Method: this is an experience report of the nursing staff in the Aeromedical Evacuation of potentially-contaminated Brazilians who were in Wuhan, China, after the outbreak of the new coronavirus. Results: the report was constructed from nursing care performed in three stages: pre-flight, screening, and flight. Pre-flight care would include aircraft configuration and material prediction. In screening, the staff was concerned with being properly attired. In the health assessment of returnees, in-flight, attention was focused on Personal Protective Equipment handling to minimize the risk of contamination by prolonged contact with potentially-contaminated passengers. Final considerations: nursing was committed to planning all the actions of this mission, which was one of the longest, strenuous and unprecedented in the history of aeromedical transport in Brazil.

Implementation of a prehospital air medical thawed plasma program: Is it even feasible?

BACKGROUND: The Prehospital Air Medical Plasma (PAMPer) trial demonstrated a 30-day survival benefit among hypotensive trauma patients treated with prehospital plasma during air medical transport. We characterized resources, costs and feasibility of air medical prehospital plasma program implementation. METHODS: We performed a secondary analysis using data derived from the recent PAMPer trial. Intervention patients received thawed plasma (5-day shelf life). Unused plasma units were recycled back to blood bank affiliates, when possible. Distribution method and capability of recycling varied across sites. We determined the status of plasma units deployed, utilized, wasted, and returned. We inventoried thawed plasma use and annualized costs for distribution and recovery. RESULTS: The PAMPer trial screened 7,275 patients and 5,103 plasma units were deployed across 22 air medical bases during a 42-month period. Only 368 (7.2%) units of this total thawed plasma pool were provided to plasma randomized PAMPer patients. Of the total plasma pool, 3,716 (72.8%) units of plasma were returned to the blood bank with the potential for transfusion prior to expiration and 1,019 (20.0%) thawed plasma units were deemed wasted for this analysis. The estimated average annual cost of implementation of a thawed plasma program per air medical base at an average courier distance would be between US $24,343 and US $30,077, depending on the ability to recycle plasma and distance of courier delivery required. CONCLUSION: A prehospital plasma program utilizing thawed plasma is resource intensive. Plasma waste can be minimized depending on trauma center and blood bank specific logistics. Implementation of a thawed plasma program can occur with financial cost. Products with a longer shelf life, such as liquid plasma or freeze-dried plasma, may provide a more cost-effective prehospital product relative to thawed plasma. LEVEL OF EVIDENCE: Therapeutic, level III.

The Effect of Team Configuration on the Incidence of Adverse Events in Pediatric Critical Care Transport.

OBJECTIVE: Specialty pediatric transport teams are widely used for pediatric interfacility transport in the United States, with little industry consensus on optimal team configuration. The aim of this study is to assess the quality of the nurse/paramedic specialty team configuration as indirectly measured by the rate of adverse events in these transports. METHODS: Retrospective analysis of pediatric transport data from a hospital-based dedicated pediatric/neonatal transport team was conducted for patients transported in 2016. Data were categorized by general characteristics of transport and analyzed for the occurrence of adverse events. RESULTS: Five hundred sixty-four cases were analyzed. Cases were described by team configuration and then by transport mode, duration, time, patient age and acuity, and disposition. The overall rate of adverse event incidence was 8.3%, chiefly centered in device and process domains. There was no significant difference in the rate of adverse events between team configurations. CONCLUSION: There was no significant difference in the rate of adverse event occurrence in nurse/paramedic team configurations versus nurse/nurse configuration. Using critical care paramedics on pediatric transport teams enables a larger volume of patients to be transported to definitive care without concerns for decrease in quality or safety.

A Novel Difficult-Airway Prediction Tool for Emergency Airway Management: Validation of the HEAVEN Criteria in a Large Air Medical Cohort.

BACKGROUND: Difficult-airway prediction tools help identify optimal airway techniques, but were derived in elective surgery patients and may not be applicable to emergency rapid sequence intubation (RSI). The HEAVEN criteria (Hypoxemia, Extremes of size, Anatomic abnormalities, Vomit/blood/fluid, Exsanguination, Neck mobility issues) may be more relevant to emergency RSI patients. OBJECTIVE: To validate the HEAVEN criteria for difficult-airway prediction in emergency RSI using a large air medical cohort. METHODS: This was a retrospective analysis using a large air medical airway registry using data from 160 bases over a 1-year period. Standard test characteristics (sensitivity, specificity, positive predictive value, negative predictive value [NPV]) for the HEAVEN criteria were calculated for overall intubation success, first-attempt success, and first-attempt success without desaturation. In addition, multivariable logistic regression was used to quantify the independent association between each of the HEAVEN criteria, as well as the total number of criteria present and intubation success after adjusting for age, gender, and clinical category (burn, medical, trauma, nontraumatic shock). RESULTS: A total of 2419 patients undergoing air medical RSI were included. Excellent NPV was observed (97% for each of the HEAVEN criteria except "Exsanguination," which had an NPV of 87% but specificity of 99%). First-attempt success was lower for each of the HEAVEN criteria, with an inverse relationship observed between total HEAVEN criteria and intubation success (first-attempt success with no criteria = 94% and with 5 + criteria = 43%). Multivariable logistic regression revealed independent associations between each of the HEAVEN criteria, as well as total number of criteria and intubation success. CONCLUSIONS: The HEAVEN criteria seem to be a useful tool to predict difficult airways in emergency RSI.

[Provision of medical care to the wounded with craniocerebral injuries at stages of medical evacuation in mountains and desert areas].

The author shows that surgery with craniocerebral injuries should be fully performed at the stage of specialized medical care. Wounded have to be evacuated not earlier than 5-7 days after surgery with the mandatory use of a special air transport ("Scalpel" or "Spasatel"), accompanied by Anaesthetist. In the absence of the possibility of surgery in 5-7 days at this stage the wounded have to be evacuated by air to the center hospitals. On the stage there are only patients requiring specialized care because of health reasons. Wounded with gunshot wounds of the soft tissues of the head, and those with mild forms of brain damage during the explosive and combat injury (concussion, mild brain contusion) can be evacuated by air transport accompanied by a doctor or paramedic at any period of time after the injury (trauma).

Probable cause in helicopter emergency medical services crashes: what role does ownership play?

BACKGROUND: The National Transportation Safety Board (NTSB) ranks helicopter emergency medical services (HEMS) as one of the most perilous occupations in the United States, with improvements in its safety of highest priority. As many injured patients are transported by helicopter, this is of particular concern to the trauma community. The use of HEMS is associated with a heightened degree of inherent risk. We hypothesized that this risk is not uniform and varies with the entity providing HEMS, specifically, commercial versus public safety providers. METHODS: The NTSB accident database was queried to identify all HEMS-involved events for the 15-year period 1998 to 2012. The NTSB investigation report was reviewed to obtain crash details including probable cause. These were analyzed on the basis of HEMS ownership. Statistical analyses were performed using analysis of variance and Fisher's exact test as appropriate. RESULTS: During the study period, 139 (6.8%) of 2,040 crashes involved HEMS and occurred across 134 cities in 37 states, killing 120 and seriously injuring 146. Of these, 118 involved commercial, 14 not-for-profit, and 7 public safety HEMS. Analyzed in 5-year blocks, no decrease in crash incidence was seen (p = 0.7, analysis of variance). Human and pilot errors were significantly more common among commercial HEMS compared with public safety HEMS (91 of 118 vs. 2 of 7, p = 0.013, and 75 of 116 vs. 1 of 7, p = 0.017, Fisher's exact test). Conditions for which training was not adequate, limited resources, inadequate equipment, and the undertaking of suboptimal trips were identified as key factors. Trauma patients were involved in 34 transports (24.5%), with a fatal or serious outcome in 68 crew/patients on 12 flights. CONCLUSION: Potentially preventable human and pilot error-related HEMS crashes are significantly more frequent among commercial compared with public safety providers. Deficiencies in training, reduced availability of equipment and resources, as well as questionable flight selection seem to play a key role. LEVEL OF EVIDENCE: Epidemiologic study, level III.

A review of the first 10 years of critical care aeromedical transport during operation iraqi freedom and operation enduring freedom: the importance of evacuation timing.

IMPORTANCE: Advances in the care of the injured patient are perhaps the only benefit of military conflict. One of the unique aspects of the military medical care system that emerged during Operation Iraqi Freedom and Operation Enduring Freedom has been the opportunity to apply existing civilian trauma system standards to the provision of combat casualty care across an evolving theater of operations. OBJECTIVES: To identify differences in mortality for soldiers undergoing early and rapid evacuation from the combat theater and to evaluate the capabilities of the Critical Care Air Transport Team (CCATT) and Joint Theater Trauma Registry databases to provide adequate data to support future initiatives for improvement of performance. DESIGN, SETTING, AND PARTICIPANTS: Retrospective review of CCATT records and the Joint Theater Trauma Registry from September 11, 2001, to December 31, 2010, for the in-theater military medicine health system, including centers in Iraq, Afghanistan, and Germany. Of 2899 CCATT transport records, those for 975 individuals had all the required data elements. EXPOSURE: Rapid evacuation by the CCATT. MAIN OUTCOMES AND MEASURES: Survival as a function of time from injury to arrival at the role IV facility at Landstuhl Regional Medical Center. RESULTS: The patient cohort demonstrated a mean Injury Severity Score of 23.7 and an overall 30-day mortality of 2.1%. Mortality en route was less than 0.02%. Statistically significant differences between survivors and decedents with respect to the Injury Severity Score (mean [SD], 23.4 [12.4] vs 37.7 [16.5]; P < .001), cumulative volume of blood transfused among the patients in each group who received a transfusion (P < .001), worst base deficit (mean [SD], -3.4 [5.0] vs -7.8 [6.9]; P = .02), and worst international normalized ratio (median [interquartile range], 1.2 [1.0-1.4] vs 1.4 [1.1-2.2]; P = .03) were observed. We found no statistically significant difference between survivors and decedents with respect to time from injury to arrival at definitive care. CONCLUSIONS AND RELEVANCE: Rapid movement of critically injured casualties within hours of wounding appears to be effective, with a minimal mortality incurred during movement and overall 30-day mortality. We found no association between the duration of time from wounding to arrival at Landstuhl Regional Medical Center with respect to mortality.

Evacuación aeromédica de pacientes críticos adultos: consideraciones de enfermería / Aeromedical evacuation of critically ill patients: nursing considerations

La evacuación aeromédica de pacientes críticos (EVACRIT) es el traslado de enfermos que se encuentran en un estado de gravedad y que requieren un manejo de su patología cuando ésta no puede ser otorgada en el centro en que han sido hospitalizados. Algunos aspectos principales a considerar son la fisiología de alturas y algunas leyes de los gases, que explican la expansión de cámaras gaseosas y la disminución de la presión inspirada de oxígeno al ascender. En nuestra institución la EVACRIT se realiza de cama a cama, es realizado por un equipo profesional compuesto por médico, enfermero(a) y paramédico el que acorde a la información obtenida en la fase de solicitud y pre-vuelo define los insumos, medios de soporte, monitoreo y fármacos a llevar, así como es conveniente conocer los tipos de aeronaves y sus prestaciones para decidir cuál es el más apropiado para el procedimiento encargado. Accedido el paciente en su cama, éste debe evaluarse para asegurar una estabilización hemodinámica, ventilatoria y de la vía aérea, titular fármacos esenciales y instalar vías venosas, catéteres y sondas; si fuera necesario, descartar el traslado sopesando riesgo-beneficio. En nuestro concepto se debe entregar al enfermo en su cama de destino, con el registro de lo acontecido durante el traslado.

Aeromedical evacuation of critically ill patients (EVACRIT) is the transfer of patients who are in a critical condition and deserve management according to their condition when it can not be granted in the center who have been hospitalized. Main aspects to consider are some high altitude physics principles and some of the laws of gases, which explain altitude descent of inspired oxygen pressure and the expansion of gaseous collections inside the body. In our institution EVACRIT is performed from bed to bed, is performed by a team composed by a physician a nurse and paramedic, who according to specific information obtained during request of the transfer, decide which means for monitoring, support, medication and supplies should be carried for that particular patient. It is highly convenient for aeromedical transport teams to be familiarized with the performances from different aircraft types so as to be able to propose and share decision about which one should be preferable for each particular procedure. Once arrived to the referring Hospital the patient´s conditions should be assessed, circulatory, ventilatory and airway stability, installation of iv lines, catheters and probes should be assured, same as titration of critical medication, considering that if necessary the transfer may be dismissed balancing risk-benefit. It is our statement that the patient should be delivered properly in his new destination critical care bed, with complete written records of his transfer.

Accuracy of prehospital diagnosis and triage of a Swiss helicopter emergency medical service.

BACKGROUND: Helicopter emergency medical services (HEMSs) have become a standard element of modern prehospital emergency medicine. This study determines the percentage of injured HEMS patients whose injuries were correctly recognized by HEMS physicians. METHODS: A retrospective level III evidence prognostic study using data from the largest Swiss HEMS, REGA (Rettungsflugwacht/Guarde Aérienne), on adult patients with trauma transported to a Level I trauma center (January 2006-December 2007). National Advisory Committee on Aeronautics (NACA) scores and the Injury Severity Score (ISS) were assessed to identify severely injured patients. Injured body regions diagnosed by REGA physicians were compared with emergency department discharge diagnoses. RESULTS: Four hundred thirty-three patients were analyzed. Median age was 42.1 years (interquartile range, 25.5-57.9). Three hundred twenty-three (74.6%) were men. Patients were severely injured, with an in-hospital NACA score of 4 or higher in 88.7% of patients and median ISS of 13. REGA physicians correctly recognized injuries to the head in 92.9%, to the femur in 90.5%, and to the tibia/fibula in 83.8% of patients. Injuries to these body regions were overdiagnosed in less than 30%. Abdominal injuries were missed in 56.1%, pelvic injuries in 51.8%, spinal injuries in 40.1%, and chest injuries in 31.2% of patients. CONCLUSION: This study shows that patients are adequately triaged by REGA physicians reflected by a NACA score 4 or higher in 88.7% of patients and a median ISS of 13. However, recognition of injured body regions seems to be challenging in the prehospital setting. Prospective studies on specific training of HEMS physicians for recognition of these injuries (e.g., portable ultrasonography, telemedicine) might help in the future. LEVEL OF EVIDENCE: Prognostic study, level III.

Long-range critical care evacuation and reoperative surgery.

Long-range critical care aeromedical evacuation has significantly contributed to the unprecedented survival during recent military operations. With advances in critical care, patients with increased injury severity and overall complexity are routinely evacuated while resuscitation is ongoing. Additional specialty teams now provide advanced pulmonary rescue therapies for the most critically ill patients. As part of the continuum of trauma care, an overseas fixed facility provides follow-on emergency surgical critical care to optimize patient outcomes before final evacuation to the continental United States.

Aerotransporte: aspectos básicos y clínicos / Air transport: basic and clinical aspects

El transporte aéreo de pacientes es una realidad cada vez más frecuente. Las condiciones y el ambiente presentado durante un vuelo, así como los cambios fisiológicos que ahí ocurren en los pacientes y en la tripulación son parámetros que el equipo médico debe conocer antes de enfrentarse a esta actividad. En este artículo se revisarán elementos propios de la aviación y de cómo estos influyen en el organismo humano; también se analizarán algunas recomendaciones a considerar.

Air transport of patients is an increasingly common reality.

Extracorporeal membrane oxygenator rescue and airborne transportation of patients with influenza A (H1N1) acute respiratory distress syndrome in a Mediterranean underserved area.

Adult respiratory distress syndrome (ARDS) secondary to H1N1 viral infection has been a worldwide medical and organizational challenge. We report our experience with extracorporeal membrane oxygenator (ECMO) rescue and transportation of patients with H1N1 ARDS within an insular and rural Mediterranean area of seven million inhabitants. A 24/7 on-call ECMO team was organized including one anesthesiologist, one cardiac surgeon, and one perfusionist. To limit missions' time to and from peripheral hospitals, airborne transportation with helicopter was the first choice. From November 2009 to January 2010, we performed 10 missions. Eight patients (80%) were placed on ECMO and transferred either on helicopter (70%) or with standard ambulance (10%). Average mission duration was nine hours (6-16 h). No complications secondary to the transportation means or to the ECMO were reported. Delivery of advanced medical technology can be achieved even in remote and underserved areas presenting geographical barriers. A multidisciplinary mobile ECMO team coordinated with adequate means of transportation could be routinely employed to rescue patients affected with other forms of severe acute hemodynamic and/or respiratory impairment.

Communication errors in dispatch of air medical transport.

BACKGROUND: Communication errors are a source of preventable medical errors. In high-risk health care settings, identifying the source and addressing root causes can reduce error and improve patient safety. While air medical transport is a high-risk setting, its sources and rates of error have been investigated only within the last several years. OBJECTIVES: This investigation examined the rate and types of communication errors during call booking of interfacility air medical transports. The primary objective was to determine the incidence and type of errors when the initial requests for transfer took place between the sending facility and transport medicine communication center. The secondary objective was to identify potential underlying causes of these errors. METHODS: Requests for urgent and emergent interfacility air medical transfers were examined prospectively during a consecutive two-week period. As the first step in call booking, sending facility staff speak directly to communication center staff and are asked for administrative, demographic, and medical details to determine patient acuity and call priority. After this information was captured, investigators contacted the sending facility to verify the information and identify any communication errors. Errors were classified as major (potentially impacting care) or minor (unlikely to impact care) and as errors of omission or commission. Common error types were presented to a management focus group to identify potential contributing causes for these errors. RESULTS: One hundred twelve calls were randomly selected during the study period, with 98 meeting study criteria. Of those, 41 (42%) calls contained a total of 65 errors. Eleven were classified as major, including five errors of omission and six errors of commission. The most common major errors were recording "no drug allergies" when a drug allergy was present (n = 4), incorrect diagnosis (n = 2), and failure to record that patients were intubated or required mechanical ventilation (n = 2 each). There were 54 minor errors, including 41 omission errors and 13 commission errors. Nearly half the errors were attributed to procedures and software. No identified error resulted in patient harm or an adverse outcome. CONCLUSIONS: Communication-based errors are common in the initial phases of call booking in air medical transport. Human and process-driven errors contribute equally to these errors.

A plastic surgical nurse's military experience.

The author thanks Rachelle Springer for her great editing skills, Marcia Spear in showing how to upload in editorial manager, and Amanda Bailey for converting the pictures to JPEGs. Have you ever entertained the idea of serving in the military? Has your sense of patriotism ever made you feel some regret that you never served your country in uniform? It was this deep spirit of patriotism and my sense of adventure that moved me to take the oath of commitment and to give 22 years of my life in service to our country. This article is my personal experience of serving in the military as a flight nurse and a commander. It provides a brief overview of the aeromedical evacuation system, different job classifications, requirements of a flight nurse, stresses of flight, and the type of aircraft used in aeromedical transport.

Maintaining the continuum of en route care.

BACKGROUND: As life-sustaining and life-preserving surgical capability is moved far forward, it creates the opportunity to salvage casualties who may have otherwise died of their wounds. The remarkable capabilities and effectiveness of the small, austere surgical resuscitation teams (mobile forward surgical team, flying ambulance surgical trauma, forward resuscitative surgery system teams) has been amply demonstrated during the recent conflicts of Operation Iraqi Freedom and Operation Enduring Freedom. DISCUSSION: The life-saving capability of far-forward surgery creates the need for a new and unique capability, which is the cornerstone of the en route care continuum, namely, the ability to move stabilized, but not necessarily stable, patients. The current system of en route care serves as a primary and indispensable portion of the continuum of critical care. SUMMARY: The scope of this article describes the origins, composition, equipment sets, medical considerations, and future directions of the en route care support process and the U.S. Air Force Critical Care Aeromedical Transport Teams.

Could simulated emergency procedures practised in a static environment improve the clinical performance of a Critical Care Air Support Team (CCAST)? A literature review.

OBJECTIVE: The Royal Air Force Critical Care Air Support Teams (CCASTs) have a philosophy to undertake transfers of critically ill patients from anywhere in the world back to a UK medical facility in a stable or improved clinical condition. The training they receive is primarily taught by traditional didactic methods, with no standardisation of education between teams that are expected to deliver care to the same standard. Notwithstanding there being no current compromise to patient care during air transfer, it was important to consider the benefits of an alternative experiential teaching modality. Experiential learning utilised in the static environment could potentially improve the current CCAST training curriculum and, therefore, improve clinical performance during air transfer. METHOD: In the absence of primary research evidence investigating beneficial teaching modalities for medical flight crews, a review of recent literature was undertaken to observe any potential relevance to the aeromedical specialty. This critical review examined recent quantitative research on various modalities of experiential learning and their influence on the critical thinking, higher cognitive and psychomotor skill acquisition by healthcare professionals in a static hospital environment. The main databases were interrogated using the following inclusion criteria: patient simulation, clinical competence, aeromedical, education, computer simulation, critical thinking and problem-based learning. The number of articles obtained was 13; these were coded on methodological strength to reduce the potential for inclusion bias. Nine studies were finally selected for review. RESULTS: Many small studies have been undertaken, primarily observing benefits of experiential learning to medical students and doctors. No studies show conclusively that simulated learning improves patient outcome, but the body of evidence suggests human patient simulators to be advantageous over other modalities because of their realistic recreation of critical events. They have proven to be at least as effective as traditional teaching by didactic methods. CONCLUSION: For CCASTs to have a standardised training curriculum, they should undertake real-time missions in a flight simulator, supported by a human patient simulator programmed to respond to the physiological changes associated with altitude. Real scenarios could then be practised, on demand, in a safe environment as an augmentation to the current training programme. Consequently, those acquired skills could then be carried out with improved proficiency during real missions with a concomitant potential for improvement in the standard of patient care.
