RESUMO

BACKGROUND: Patients with acute myocardial infarction (AMI) or acute trauma (AT) are transported by air to save time. Helicopter Emergency Medical Service (HEMS) provides both flights to and from the emergency scene, as well as interhospital transport (interHtransport). OBJECTIVES: The objective of this study was to compare aeromedical transport and HEMS missions of AMI and AT patients regarding safety, medical procedures and the length of flights. MATERIAL AND METHODS: This is a case-control study analyzing the medical history records of AMI and AT patients transported between hospitals and from the scene identified using ICD-10 codes. Research of customary data (age, sex and general health status measured with Glasgow Coma Scale (GCS) and Revised Trauma Score (RTS)) was performed. RESULTS: There were 48,555 flights in the years 2011-2016, of which 7,645 (15.7%) were interhospital (19% AMI and 12% AT). Out of these, 40,910 (84.3%) HEMS missions were to patients on the scene (10% AMI and 13% AT). No fatalities were noted. The AMI GCS score was higher than in AT patients: 15.0 vs 14.0, respectively. The medical procedures during transport of AMI patients between hospitals and from the scene were the following: cardiopulmonary resuscitation (CPR): 6 vs 73 cases (p < 0.001); oxygen therapy: 41.1% vs 50.2%, respectively. The median distance was 59.4 km vs 52.1 km (p < 0.001), while median flight time was 45.0 min vs 38.0 min (p < 0.001), respectively. Regarding AT patients, the procedures performed (during interhospital and from the scene transport) were the following: CPR: 5 vs 244 cases (p < 0.001); intubation: 10.7% vs 17.3% (p < 0.001); sedation: 50.1% vs 24.3% (p < 0.001); oxygen therapy: 17.6% vs 36.6% (p < 0.001); spinal board: 17.1% vs 66% (p < 0.001); cervical collar: 15.9% vs 63.4% (p < 0.001), respectively. Interhospital transport and HEMS mission median flight distance was 135.9 km vs 56.3 km (p < 0.001), while median flight time was 66.0 min vs 45.0 min (p < 0.001), respectively. CONCLUSIONS: Aeromedical transport is safe and very rarely requires resuscitation during the flight. The long distances of flights and time required can reflect the scarcity of trauma centers (TCs) compared to cardiovascular wards. The location of hemodynamic centers in Poland is optimal.

RESUMO

INTRODUCTION: Although bear attacks on humans are uncommon, the incidence has slowly risen as human populations increasingly encroach on wilderness habitat. In the Kingdom of Bhutan, Himalayan black bear attacks occur regularly. Bears preferentially attack the face, often causing injuries that require surgical airway management. We sought to determine how often patients injured by Himalayan black bears required airway management during initial resuscitation. METHODS: We conducted a retrospective review of emergency department and admission records of the 3 referral hospitals in Bhutan. We identified all victims of bear attacks in Bhutan who received emergency airway management, including surgical airway management during the period from August 2013 to December 2017. RESULTS: There were 21 patients who were treated for injuries from bear attacks during the study period. Of these, 12 required emergency airway management. Three patients who required emergency airways (2 intubations, 1 surgical airway) were attacked near a regional referral hospital and received care at that hospital. The remaining 9 patients received care from the helicopter emergency medical services (HEMS) retrieval team (1 intubation, 8 surgical airways). CONCLUSIONS: The use of highly trained HEMS critical care retrieval teams may improve outcomes in critically injured patients who require time-critical airway management in remote areas. Countries such as Bhutan with populations far from emergency and critical care might benefit from the establishment of HEMS critical care retrieval services. HEMS teams providing care while retrieving patients from austere environments should be expert in emergency airway management.

RESUMO

BACKGROUND: A national Helicopter Emergency Medical Service (HEMS) was introduced in Denmark in 2014 to ensure the availability of physician-led critical care for all patients regardless of location. Appropriate dispatch of HEMS is known to be complex, and resource utilisation is a highly relevant topic. Population-based studies on patient characteristics are fundamental when evaluating and optimising a system. The aim of this study was to describe the patient population treated by the Danish HEMS in terms of demographics, pre-hospital diagnostics, severity of illness or injury, and the critical care interventions performed. METHOD: The study is a retrospective nationwide population-based study based on data gathered from the Danish HEMS database. We included primary missions resulting in a patient encounter registered between October 1st 2014 and April 30th 2018. RESULTS: Of 13.391 dispatches registered in the study period we included 7133 (53%) primary missions with patient encounter: 4639 patients were air lifted to hospital, 174 patients were escorted to hospital by the HEMS physician in an ambulance, and in 2320 cases HEMS assisted the ground crew on scene but did not escort the patient to hospital. Patient age ranged from 0-99 years and 64% of the population were men. The median age was 60 years. The main diagnostic groups were cardio-vascular emergencies (41%), trauma (23%) and neurological emergencies (16%). In 61% of the cases, the patient was critically ill/injured corresponding to a NACA (National Advisory Committee for Aeronautics) score between 4 and 7 (both included). In more than one third of the missions a critical care intervention was performed. Ultrasound examination and endo-tracheal intubation were the critical care interventions most frequently performed (21% and 20%, respectively). CONCLUSION: The national Danish HEMS primarily attends severely ill or injured patients and often perform critical care interventions. In addition, the Danish HEMS provides rapid transport to highly specialised treatment for patients in the more rural parts of the country. Patients with cardio-vascular emergencies, trauma and neurological emergencies are among those patient groups most commonly seen. We conclude that the overall dispatch profile appears appropriate but emphasise that continuous development and refinement is essential.

RESUMO

Trauma is a time-critical condition. Helicopters are thought to enhance the accessibility to trauma centers, but this benefit is poorly quantified. The aim of this study was to conduct a geographical analysis of the added benefit provided by helicopters, over ground transport. This study uses geospatial analysis. Helicopter bases and Level I and II designated trauma centers were geocoded. 60-minute drive-time and elliptical flight-time isochrones were mapped with ArcGIS™ (Esri, Redlands, CA). Calculations included allowance for mission ground time (MGT). We compared the proportion of the population that could be taken to Level I and II trauma centers, within 60 minutes, by road and by air. Using a 30-minute MGT model, helicopters permit 279,317 additional residents (5.8%) access to a Level I trauma center within 60 minutes. Using the 20-minute MGT model, 1,089,177 more residents (22.8%) would have access to Level I trauma center care. The benefits were marginally greater for access to Level I and II trauma center care. Helicopters enhance access to specialist trauma center care, but the benefit is small and dependent on MGT. Consideration should be given to the siting of helicopters, particularly in relation to trauma patients, MGT, and the timely response of EMS when determining the triage for helicopter transport.

RESUMO

INTRODUCTION: Optimal dispatch of emergency medical services relies on accurate time estimates of the various prehospital stages. Hoist rescue work time intervals performed by the search and rescue (SAR) helicopter service in Norway have not been studied to date. We aimed to describe the epidemiologic, operational, and medical aspects of the SAR service in southeast Norway. To complement the prehospital timeline, we performed simulated hoist operations. METHODS: We reviewed time and patient descriptors and medical interventions in hoist operations performed at a SAR base over 5 y. In addition, a simulation study measuring hoist rescue time intervals was performed. Data are presented as mean±SD, except National Advisory Committee for Aeronautics (NACA) scores, which are presented as modes. RESULTS: There were 148 hoist operations performed during the study period, involving 180 patients. Time to take-off was 13±7 min. There were 88 patients (49%) who were injured; 53 (29%) had a medical condition, and 39 (22%) were evacuees. The mode of the NACA score was 3. Forty-five patients (25%) had an NACA score of 4 to 6. Medical interventions were performed on 77 patients (43%) in 73 operations (49%). Nine patients (5%) were endotracheally intubated, and 1 thoracostomy was performed. The simulated rescuer access time was 4±2 min, the simulated anesthesiologist access time was 6±2 min, and the simulated hoist extrication time was 13±2 min. CONCLUSIONS: Hoist rescue was performed in 10% (n=148) of the SAR operations. New information about hoist extrication time intervals can improve rescue helicopter dispatch accuracy.

RESUMO

BACKGROUND: Making ethically sound treatment limitations in prehospital care is a complex topic. Helicopter Emergency Medical Service (HEMS) physicians were surveyed on their experiences with limitations of care orders in the prehospital setting, including situations where they are dispatched to healthcare facilities or nursing homes. METHODS: A nationwide multicentre study was conducted among all HEMS physicians in Finland in 2017 using a questionnaire with closed five-point Likert-scale questions and open questions. The Ethics Committee of the Tampere University Hospital approved the study protocol (R15048). RESULTS: Fifty-nine (88%) physicians responded. Their median age was 43 (IQR 38-47) and median medical working experience was 15 (IQR 10-20) years. All respondents made limitation of care orders and 39% made them often. Three fourths (75%) of the physicians were often dispatched to healthcare facilities and nursing homes and the majority (93%) regularly met patients who should have already had a valid limitation of care order. Every other physician (49%) had sometimes decided not to implement a medically justifiable limitation of care order because they wanted to avoid conflicts with the patient and/or the next of kin and/or other healthcare staff. Limitation of care order practices varied between the respondents, but neither age nor working experience explained these differences in answers. Most physicians (85%) stated that limitations of care orders are part of their work and 81% did not find them especially burdensome. The most challenging patient groups for treatment limitations were the under-aged patients, the severely disabled patients and the patients in healthcare facilities or residing in nursing homes. CONCLUSION: Making limitation of care orders is an important but often invisible part of a HEMS physician's work. HEMS physicians expressed that patients in long-term care were often without limitations of care orders in situations where an order would have been ethically in accordance with the patient's best interests.

RESUMO

The aim of this study was to investigate the experiences of medical transportation of Korean travelers who suffered accidents abroad and then transferred home by our aeromedical team.We collected demographic and clinical data on patients injured while traveling abroad from January 2013 to July 2017. Descriptive analyses based on 4 different transportation methods and transport time since hospitalization were performed.A total of 33 patients were repatriated during the study period. Of these, 28 (84.8%) were trauma cases with pedestrian injuries being the most common (11 cases; 39.3%). Twenty patients were repatriated by flight-stretchers, 6 by flight-prestige, 2 by ship, and 5 by air ambulance. The air ambulance was the most expensive (average 61,124 US Dollars) mode of transportation (P = .001) and the ship took the longest time (14 hours) to transport patients back to Korea from regions with similar distance (P = .0023).We experienced medical repatriation of 33 seriously injured Korean travelers back to South Korea. Transfer time should be an important considering factor and directly contacting and communicating with the specialized staff of foreign hospitals could also be very important to reduce unnecessary overseas hospital stay and cost incidence.

RESUMO

Helicopter air ambulance services (HAA) increasingly operate during darkness, and the cockpit crew prefers a dimmed light to be used in the cabin. Our HAA team is currently researching the use of dimmed red light. We encountered a downside to the use of red light-some texts and symbols became virtually invisible.

RESUMO

BACKGROUND: A reduction in pre-hospital scene time for patients with penetrating trauma is associated with reduced mortality, when combined with appropriate hospital triage. This study investigated the relationship between presence of pre-hospital enhanced care teams (ECT) (Critical Care Paramedics (CCPS) or Helicopter Emergency Medical Service (HEMS)), on the scene time and triage compliance, of penetrating trauma patients in a UK ambulance service. The primary outcome was whether scene time reduces when an ECT is present. A secondary outcome was whether the presence of an ECT improved compliance with the trust's Major Trauma Decision Tree (MTDT). METHODS: All suspected penetrating trauma incidents involving a patient's torso were identified from the Trust's computer-aided dispatch (CAD) system between 31st March 2017 and 1st April 2018. Only patients who sustained central penetrating trauma were included. Any incidents involving firearms were excluded due to the prolonged times that can be involved when waiting for specialist police units. Data relevant to scene time for each eligible incident were retrieved, along with the presence or absence of an ECT. The results were analysed to identify trends in the scene times and compliance with the MTDT. RESULTS: One hundred seventy-one patients met the inclusion criteria, with 165 having complete data. The presence of an ECT improved the median on-scene time in central stabbing by 38% (29m50s vs. 19m0s, p = 0.03). The compliance with the trust's MTDT increased dramatically when an ECT is present (81% vs. 37%, odds ratio 7.59, 95% CI, 3.70-15.37, p < 0.0001). CONCLUSIONS: The presence of an ECT at a central stabbing incident significantly improved the scene time and triage compliance with a MTDT. Ambulance services should consider routine activation of ECTs to such incidents, with subsequent service evaluation to monitor patient outcomes. Ambulance services should continue to strive to reduce scene times in the context of central penetrating trauma.

RESUMO

INTRODUCTION: Adverse weather and poor visual cues are common elements in night-time Helicopter Emergency Medical Service (HEMS) operations contributing to spatial disorientation and fatal accidents. Pilots are required to make weather-related preflight risk assessments to accept or reject a flight. This study's aim was to develop predictive risk assessment tools based on historical accident data to assist the decision-making process.METHODS: We analyzed 32 single-pilot HEMS night-time visual flight rules fatal accidents to identify contributory risk factors. Logistic regression analysis was used to develop prediction nomograms for nonvisual meteorological conditions (non-VMC), cause and nonsurvivable accidents as dependent variables. Risk factors such as temperature dew point spread, elevation difference, and years of HEMS pilot experience, were entered as continuous variables. Flight crew composition, pilot DTE (domain task experience) and flight rule capability, primary missions, and temperature dew point spread were entered as categorical variables. A point scoring matrix transposed model probability to likelihood and consequence severity.RESULTS: The nomograms correctly predicted the likelihood of entering non-VMC, accident cause, and sustaining a nonsurvivable accident in 75%, 55%, and 94% of cases, respectively. Using data from a recent nonsurvivable HEMS accident, the nomogram estimated a 92% probability (Very Likely) of nonsurvivable accident if visual cues were lost.CONCLUSION: These nomograms can provide preflight information to predict the likelihood of adverse safety outcomes occurring during a planned HEMS mission. While further development work is needed, this approach has the potential to improve HEMS operational safety.Aherne BB, Zhang C, Chen WS, Newman DG.

RESUMO

OBJECTIVES: Physician-staffed helicopter transport is faster than ground transport and allows for prompt medical care of patients in rural areas. In this study, we evaluated the relationship between helicopter transport and the prognosis of patients with acute cerebral infarction in rural Japan. METHODS: This retrospective, observational study included 546 patients with acute cerebral infarction attending Aomori Prefectural Central Hospital, which serves a rural region of Japan. Patients were separated into 2 transport groups: physician-staffed helicopter emergency medical services and ground emergency medical services. Patients were assessed for stroke severity, treatment, and prognosis. RESULTS: Of the 546 patients, 11.2% were transported by physician-staffed helicopter emergency medical services and 88.8% by ground emergency medical services. Although the distance transported was significantly longer in the physician-staffed helicopter emergency medical services group, the time from onset to reaching our hospital was similar between the groups. National Institutes of Health Stroke Scale on admission and final prognosis were significantly worse with physician-staffed helicopter emergency medical services than with ground emergency medical services. Multivariate analysis showed no association between transport system and prognosis. CONCLUSIONS: In this study, patients transported by physician-staffed helicopter emergency medical services had more severe stroke symptoms and poorer functional outcomes than those transported by ground emergency medical services. However, the transport time was shorter for physician-staffed helicopter emergency medical services; thus, physician-staffed helicopter emergency medical services may be useful for reducing transport time for patients in rural Japan.

RESUMO

The 700+ Caribbean islands present a vast area of operations (AO) with challenges providing healthcare to the local population and deployed personnel. Predisaster host nation medical care relied on casevac for basic primary and secondary healthcare, with medivac by air for advanced medical treatment. Disruption to facilities and transport links by Hurricane Irma rendered the native healthcare system on its knees. During Op RUMAN, the Royal Air Force Medical Services (RAFMS) provided expertise in prehospital emergency care and critical care aeromed to enable emergency treatment and access to definitive care for local nationals and our own personnel. The ability to provide independent, safe aeromedical care across a variety of aviation platforms is unique to the RAFMS. The AO did not fit any current doctrine; an adaptable, functional unit concept was adopted to enable care to the walking wounded through to critical care along prolonged timelines.

RESUMO

BACKGROUND: Helicopters are widely used to facilitate the transport of trauma patients, from the scene of an incident to the hospital. However, the use of helicopters may not always be appropriate. The aim of this project was to conduct a geospatial analysis of helicopter transport to a Level I trauma center. METHODS: Retrospective geospatial analysis of trauma registry data, 2013 to 2018. We included all adult (≥16) trauma patients brought to the trauma center directly from the scene. Data were geocoded and analyzed using arcGIS. Drive times and flight times were calculated using Google Maps. Flight times included the time required to reach the incident location. RESULTS: Two thousand eight hundred ninety-three patients were identified, and 1,911 had incident locations recorded and were therefore included in the analysis. The median age was 41 years (interquartile range [IQR], 27-58 years). Twenty-four percent of the patients had suffered severe injuries (Injury Severity Score [ISS], 16-25), 17% very severe injuries (ISS > 25), 24% moderately severe injuries, and 36% minor injuries (ISS, 1-8). The overall geographical distribution was centroidal, although with a concentration of case volume in the vicinity, and to the northeast, of the trauma center. Median flight time was 60 minutes (IQR, 52-69 minutes), and median drive time 65 minutes (IQR, 54-86 minutes). In 33% of the patients, the calculated drive time to the trauma center was shorter than the calculated flight time when considering the time for the helicopter to reach the scene. CONCLUSION: The majority of patients taken to our level I trauma center by helicopter are injured in relatively close proximity. One in four patients is severely or very severely injured, but one third of the patients have only minor injuries. Over a quarter of trauma patients might have reached hospital more quickly if they had been taken by road, rather than helicopter. LEVEL OF EVIDENCE: Epidemiological/geographical study, level V.

RESUMO

OBJECTIVES: To characterise the people retrieved by the Royal Flying Doctor Service (RFDS) for treatment of mental and behavioural disorders, and to assess mental health care provision in rural and remote areas. DESIGN: Prospective review of routinely collected RFDS and Health Direct data. SETTING, PARTICIPANTS: RFDS aeromedical retrievals of patients from anywhere in Australia except Tasmania during 1 July 2014 - 30 June 2017 for the treatment of mental or behavioural disorders. MAIN OUTCOME MEASURES: Retrievals by ICD-10 mental and behavioural disorder diagnoses. RESULTS: 2257 patients were retrieved by the RFDS for treatment of mental or behavioural disorders, including 1394 males (62%) and 863 females (38%); 60% of patients were under 40 years of age, 35% identified as Indigenous Australians. The most frequent mental and behavioural disorders were schizophrenia (227 retrievals, 16.5% of retrievals with ICD diagnoses), bipolar affective disorder (185, 13.5%), and depressive episodes (153, 11.2%). Psychoactive substance misuse triggered 194 retrievals (14.2%), including misuse of multiple drugs (85, 6.2%), alcohol (61, 4.5%), and cannabinoids (25, 1.8%). The mean age of patients retrieved for treatment of substance misuse (29.6 years; SD, 11.6 years) was lower than for retrieved patients overall (37.0 years; SD, 19.3 years); 38 of 194 patients retrieved after psychoactive substance misuse (19.6%) were under 19 years of age. Most retrieval sites were rural and remote communities with low levels of mental health care support. CONCLUSION: Mental and behavioural disorders are an important problem in rural and remote communities, and acute presentations trigger a considerable number of RFDS retrievals.

RESUMO

BACKGROUND: Helicopter emergency medical services improve survival in some injured patients but current utilization leads to significant overtriage with considerable numbers of transported patients discharged home from the emergency department or found to have non-time-sensitive injuries. Current triage models for utilization are complex and untested. METHODS: Data from a state trauma registry were reviewed from 1987 to 1993 and from 2013 to 2015 and compared. Data from 2013 to 2015 were analyzed for field information found to influence mortality and a model for low mortality-risk patients designed. RESULTS: Indexed to population, a major increase in numbers of injured patients transported directly to designated trauma centers (39.849-167.626/100,000/year) occurred with an increased portion transported by helicopter emergency medical services from 7.28% to 9.26%. A simple triage tool to predict low mortality rates was designed utilizing results from logistic regression. Nongeriatric adult patients (age, 16.0-69.9 years) with a blunt injury mechanism, normal Glasgow Coma Scale motor score, pulse rate of 60 bpm to 120 bpm and respiratory rate of 10 breaths per minute to 29 breaths per minute are at low risk for mortality. Cost for helicopter transportation was substantially higher than ground transportation based on available data. Cost differentials in transport mode increased patient financial risk when helicopter transportation was utilized. CONCLUSION: Implementing a simple decision tool designating nongeriatric adult patients with a blunt injury mechanism, normal Glasgow Coma Scale motor score, systolic blood pressure greater than 90 mm Hg, pulse rate of 60 bpm to 120 bpm, and respiratory rate of 10 breaths per minute to 29 breaths per minute to ground transportation would result in substantial savings without an increase in mortality and reduce risk of patient financial harm. LEVEL OF EVIDENCE: Prognostic/Epidemiological study, level IV. Economic and value based evaluation, level IV.

BACKGROUND: Geographical service areas are used as descriptive system indicators in Emergency Medical Service (EMS) related studies and reporting templates. The actual service area may differ significantly from administrative areas; this may lead to inaccuracy in determining indicator values, such as population or mission density, thus making it biased when comparing results between different areas and organizations. The aim of this study was to introduce a univocal, repeatable and easily adaptable method to determine the actual service area of a helicopter emergency medical service (HEMS) unit for statistical, quality measurement and research purposes using widely available geographical information (GIS) and statistical analysis tools. METHODS: The method was first tested with Tampere HEMS unit. All accepted missions in 2017 were extracted from FinnHEMS database (FHDB). We calculated distance from HEMS base to each accepted mission location. Missions were reordered based on the distance and 99th and 95th percentiles were calculated for mission distances. Convex hulls including 100, 99 and 95% of the missions, and the population and area covered by these missions, were then calculated. The method was repeated for all Finnish HEMS bases. RESULTS: Approximately 90% of Tampere HEMS unit's accepted missions took place within 100 km from the base. 10.9% of the missions occurred outside of the administrative service area. 95% convex hull areas are most in line with the everyday experience of where the units actually operate. In Tampere, the 95% convex hull area corresponds to 76,5% of the administrative area's population and to 89,8% of its area. Calculating the 95% convex hull areas for all Finnish HEMS units results in service areas that overlap at some points, and some areas of the country fall outside of all HEMS service areas. CONCLUSIONS: Administrative areas do not correspond to the actual service areas of HEMS units. The service area of a HEMS unit defined by administrative boundaries may differ significantly from actual operations. Using historical mission data to create a convex hull that incorporates mission locations could offer a standardized and comparable solution for determining actual HEMS unit service areas, which can be used for statistical comparison, quality measurement and system development.
