Abstract
BACKGROUND One of the most significant advantages of Helicopter Emergency Medical Service (HEMS) in disaster relief efforts is their ability to reach inaccessible or remote areas quickly. This is especially important in the aftermath of natural disasters such as earthquakes, floods, or hurricanes, where roads may be blocked or damaged, and conventional ground transportation may not be available. There are many factors can affect the performance of Helicopter Emergency Medical Service (HEMS) in disasters. This study aims to investigate the factors affecting the Helicopter Emergency Medical Service (HEMS) in disasters. METHODS The systematic search in Cochran Library, PubMed, Scopus, Science Direct, Web of Science, ProQuest, and Google Scholar databases between the first of January in 1975 and the thirty-first of May in 2023. The articles were selected based on the keywords of the authors. At last, the criteria were extracted from the selected ones. RESULTS The primary search included 839 articles. After studying their title, abstract, and full context, only nine articles, including two qualitative and seven quantitative ones, were chosen for analysis. After analysis and extracting data from the final studies, the preparation factors were categorized into 6 general classes of human resources: training and practicing, management, instructions and standards, equipment, and structure. Among these, the role of training is highlighted by holding practice and maneuvers to improve and prepare the personnel and manage disasters and incidents. CONCLUSION The results obtained from this systematic review provide a total view of the factors affecting the preparation of the air ambulance during disasters and incidents. It is recommended that senior managers and policy makers use the findings of the present study to identify the factors which affect preparedness of HEMS in disasters and take the necessary measures to eliminate to obstacles.

Abstract
The aim of the study was to present characteristics of patients transported in incubators by crews of Helicopter Emergency Medical Service (HEMS) and Emergency Medical Service (EMS) of the Polish Medical Air Rescue as well as the character of their missions. The study was based on the method of retrospective analysis of neonatal transports with the use of transport incubators by the crews of HEMS and EMS of the Polish Medical Air Rescue. The study covered 436 medical and rescue transports of premature babies and full-term newborns in the period between January 2012 and December 2018. The study group consisted mainly of male patients (55.05%) who, on the basis of the date of delivery, were qualified as full-term newborns (54.59%). During the transport their average age was 37.53 (standard deviation, SD 43.53) days, and their average body weight was 3121.18 (SD 802.64) grams. A vast majority of neonatal transports were provided with the use of a plane (84.63%), and these were medical transports (79.36%). The average transport time was 49.92 (SD 27.70) minutes with the average distance of 304.27 km (SD 93.05). Significant differences between premature babies and full-term newborns were noticed in terms of age and body weight at the moment of transport, diagnosis based on the International Statistical Classification of Diseases and Related Health Problems (ICD-10), the most commonly used medications (prostaglandin E1, glucose, furosemide, vitamins), National Advisory Committee for Aeronautics (NACA) scale rate as well as the mission type and the presence of an accompanying person.

Abstract
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.

Abstract
INTRODUCTION Mortality due to various causes, despite continuous efforts to improve the quality of medical services, is a serious problem for modern healthcare systems. Ischaemic heart disease and stroke are the cause of over 15 million deaths annually, and are therefore known as the world's number one killer. OBJECTIVE The aim of this study is to characterise the missions and the most common reasons for dispatching Helicopter Emergency Medical Service (HEMS) crews, with special emphasis on the differences between urban and rural areas. MATERIAL AND METHODS The study was conducted using a retrospective analysis of HEMS missions, including flights to accidents and diseases carried out by HEMS crews in Poland from January 2014 - December 2018. The final analysis included 35,213 cases of HEMS missions. RESULTS The study group consisted mainly of male patients (66.40%), aged 50-64 (22.06%), mean age of the entire analysed group - 47.71 (SD: 25.96). The main reason for HEMS missions were strokes (21.63%). Analysis of patients' clinical status revealed that the clinical status of patients treated in rural areas was more severe, which was indicated by the Glasgow Coma Scale - GCS (12.03 vs 12.35) and the Revised Trauma Scale - RTS (10.14 vs 10.60) scores. When assessed by the National Advisory Committee for Aeronautics (NACA) score, body injuries and fatal diseases were observed more often in patients in rural areas (NACA 7 6.12% vs 3.46%) (p<0.05). CONCLUSIONS Multi-organ injuries, head traumas, sudden cardiac arrest, traumatic brain injuries, collapse and epilepsy, were more frequent reasons for HEMS missions in rural areas than in urban areas.

Abstract
The aim of the study was to identify the characteristics of missions performed by HEMS (Helicopter Emergency Medical Service) crews and the analysis of health problems, which are the most common cause of intervention in rural areas in Poland. The study was conducted using a retrospective analysis based on the medical records of patients provided by the HEMS crew, who were present for the emergencies in rural areas in the period from January 2011 to December 2018. The final analysis included 37,085 cases of intervention by HEMS crews, which accounted for 54.91% of all the missions carried out in the study period. The majority (67.4%) of patients rescued were male, and just under a quarter of those rescued were aged between 50-64 years. Injuries (51.04%) and cardiovascular diseases (36.49%) were the main diagnoses found in the study group. Whereas injuries were significantly higher in the male group and patients below 64 years of age, cardiovascular diseases were higher in women and elderly patients (p < 0.001). Moreover, in the group of women myocardial infarction was significantly more frequent (30.95%) than men, while in the group of men head injuries (27.10%), multiple and multi-organ injuries (25.93%), sudden cardiac arrest (14.52%), stroke (12.19%), and epilepsy (4.95%) was significantly higher. Factors that are associated with the most common health problems of rural patients are: gender and age, as well as the seasons of the year and the values of the Glasgow Coma Scale (GCS), Revised Trauma Score (RTS), and National Advisory Committee for Aeronautics (NACA) used to assess the clinical status of patients.

Abstract
INTRODUCTION The Revised Trauma Score (RTS) accurately identifies trauma patients at high risk of adverse events or death. Less is known about its usefulness in the general population and non-trauma recipients of Helicopter Emergency Medical Service (HEMS). The RTS is a simple tool and omits a lot of other data obtained during clinical evaluation. The aim was to assess the role of the RTS to identify patients at risk of major complications (death, cardiopulmonary resuscitation, defibrillation, intubation) in the general population of HEMS patients. Clinical factors beyond the RTS were analyzed to identify additional prognostic factors for predicting major complications. MATERIAL AND METHODS A retrospective analysis of medical records of adult patients routinely collected during HEMS missions in the years 2011-2014 was performed. RESULTS The analysis included 19 554 HEMS missions. Patients were 55 ±20 years old and 68% were male. The most common indication for HEMS was diseases of the circulatory system - 41%. Major complications occurred in 2072 (10.6%) cases. In the general population of HEMS patients, the RTS accurately identified individuals at risk of major complications at a cut-off value of 10.5 and area under the curve (AUC) of 93.5%. In multivariate analysis, additional clinical data derived from clinical examination (ECG; skin, pupil and breathing examination) significantly but marginally improved the accuracy of RTS assessment: AUC 95.6% (p < 0.001 for the difference). CONCLUSIONS The Revised Trauma Score accurately identifies individuals at risk of major complications during HEMS missions regardless of the indication. Additional clinical data significantly but marginally improved the accuracy of RTS in the general population of HEMS patients.

Abstract
In 2008, the Polish Medical Air Rescue started replacing its fleet with modern EC135 machines. To ensure the maximum possible safety of the missions performed both in the period of implementing the change and later on, the management prepared a strategy of training its crews to use the new type of helicopter. The analysis of incidents that occurred during 2006–2009 showed that both the human and the technical factors must be carefully considered. Moreover, a risk analysis was conducted to reduce the risk both during general crew training and in the course of particular flight operations. A four-stage strategy of training pilots and crew members was worked out by weighing up all the risks. The analysis of data from 2010 to 2013 confirmed that the risk connected with flying and with all the activities involved in direct support aircraft operations is under control and lowered to an acceptable level.

Abstract
INTRODUCTION The utilisation of Helicopter Emergency Medical Services (HEMS) in response to equestrian accidents has been an integral part of operations for many years throughout the UK. The recent establishment of major trauma networks in the UK has placed great emphasis on the appropriate tasking of HEMS units to cases where added benefit can be provided and the incidence of time critical injury in cases of equestrian accidents has been shown to be low. This study assesses the impact made on the utilisation of the different HEMS resources for cases of equestrian accidents within the West Midlands following the launch of the regional trauma network. METHODS We present a retrospective analysis of all equestrian accidents attended by Midlands Air Ambulance (MAA) between 1 April 2012 and 1 April 2013. Data were abstracted from the MAA operational database relating to mission activations/scene attendances; team configuration (physician led and Critical Care Paramedic (CCP) led); on-scene interventions; mission timings and patient conveyance by helicopter. RESULTS A total of 114 activations involved equestrian accidents (6% of overall workload). The contribution of equestrian accidents to overall workload was similar for physician led and CCP-led (69/1069) platforms (5% vs. 6%, p=0.50). Only three patients (3%) required pre-hospital RSI during the period analysed and there were no recorded cases of ketamine administration for analgesia/conscious sedation. In approximately half of all scene attendances patients did not require any medication to be administered by the HEMS team. The vast majority of incidents occurred in rural locations with over 80% of patients conveyed to hospital by helicopter. The average mission time for scene attendances resulting in conveyance by helicopter was in excess of 90 min on both types of platform. CONCLUSIONS There is a clear requirement for the design and implementation of informed and intelligent tasking models to respond to the need for assistance in equestrian accidents. Such models may include preferential deployment of non-physician led HEMS resources to equestrian accidents or the utilisation of other local or regional resources, such as those with specially adapted vehicles with off road capability, to offer alternative solutions to access/egress challenges posed in such cases.

Abstract
BACKGROUND Intraosseous access (IO) is a rapid and safe alternative when peripheral venous access is difficult. Our aim was to summarize the first three years experience with the use of a semi-automatic IO device (EZ-IO(®)) in German Helicopter Emergency Medical Service (HEMS). METHODS Included were all patients during study period (January 2009-December 2011) requiring an IO access performed by HEMS team. Outcome variables were IO rate, IO insertion success rates, site of IO access, type of EZ-IO(®) needle set used, strategy of vascular access, procedure related problems and operator's satisfaction. RESULTS IO rate was 0.3% (348/120.923). Overall success rate was 99.6% with a first attempt success rate of 85.9%; there was only one failure (0.4%). There were three insertion sites: proximal tibia (87.2%), distal tibia (7.5%) and proximal humerus (5.3%). Within total study group IO was predominantly the second-line strategy (39% vs. 61%, p<0.001), but in children<7 years, in trauma cases and in cardiac arrest IO was more often first-line strategy (64% vs. 28%, p<0.001; 48% vs. 34%, p<0.032; 50% vs. 29%, p<0.002 respectively). Patients with IO access were significantly younger (41.7±28.7 vs. 56.5±24.4 years; p<0.001), more often male (63.2% vs. 57.7%; p=0.037), included more trauma cases (37.3% vs. 30.0%; p=0.003) and more often patients with a NACA-Score≥5 rating (77.0% vs. 18.6%; p<0.001). Patients who required IO access generally presented with more severely compromised vital signs associated with the need for more invasive resuscitation actions such as intubation, chest drains, CPR and defibrillation. In 93% EZ-IO(®) needle set handling was rated "good". Problems were reported in 1.6% (needle dislocation 0.8%, needle bending 0.4% and parafusion 0.4%). CONCLUSIONS The IO route was generally used in the most critically ill of patients. Our relatively low rate of usage would indicate that this would be compatible with the recommendations of established guidelines. The EZ-IO(®) intraosseous device proved feasible with a high success rate in adult and pediatric emergency patients in HEMS.
