The Association between Cardiopulmonary Resuscitation in Out-of-Hospital Settings and Chest Injuries: A Retrospective Observational Study.

Abstract: The aim of this study was to assess the risk of cardiopulmonary resuscitation (CPR) performed in out-of-hospital settings for chest injuries in patients with out-of-hospital cardiac arrest (OHCA). This retrospective, observational study was conducted in an emergency critical care medical center in Japan. Non-traumatic OHCA patients transferred to the hospital from April 2013 through August 2016 were analyzed. The outcome was defined by chest injuries related to CPR, which is composite of rib fractures, sternal fractures, and pneumothoraces. A multivariate logistic regression analysis was performed to assess the independent risk factors for chest injuries related to CPR. The threshold of out-of-hospital CPR duration that increased risk of chest injuries was also assessed. A total of 472 patients were identified, of whom 233 patients sustained chest injuries. The multivariate logistic regression model showed that the independent risk factors for chest injuries were age and out-of-hospital CPR duration (age: AOR=1.06 [95% CI, 1.04 to 1.07]; out-of-hospital CPR duration: AOR=1.03 [95% CI, 1.01 to 1.05]). In-hospital CPR duration was not an independent risk factor for chest injuries. When the duration of out-of-hospital CPR extended over 15 minutes, the likelihood of chest injuries increased; however, this association was not statistically significant. Long duration of out-of-hospital CPR was an independent risk factor for chest injuries, possibly due to the difficulty of maintaining adequate quality of CPR. Further investigations to assess the efficacy of alternative CPR devices are expected in cases requiring long transportation times. Takayama W , Koguchi H , Endo A , Otomo Y .

Prehospital Airway Procedures Performed in Trauma Patients by Ground Forces in Afghanistan.

Abstract: Airway management is of critical importance in combat trauma patients. Airway compromise is the second leading cause of potentially survivable death on the battlefield and accounts for approximately 1 in 10 preventable deaths. Reports from the Iraq and Afghanistan wars indicate 4-7% incidence of airway interventions on casualties transported to combat hospitals. The goal of this study was to describe airway management in the prehospital combat setting and document airway devices used on the battlefield. This study is a retrospective review of casualties that required a prehospital life-saving airway intervention during combat operations in Afghanistan. We obtained data from the Prehospital Trauma Registry (PHTR) that was linked to the Department of Defense Trauma Registry (DoDTR) for outcome data for the time period between January 2013 and September 2014. 705 total trauma patients were included, 16.9% required a prehospital airway management procedure. There were 132 total airway procedures performed, including 83 (63.4%) endotracheal intubations and 26 (19.8%) nasopharyngeal airway placements. Combat medics were involved in 48 (36.4%) of airway cases and medical officers in 73 (55.3%). Most (94.2%) patients underwent airway procedures due to battle injuries caused by explosion or gunshot wounds. Casualties requiring airway management were more severely injured and less likely to survive as indicated by injury severity score, responsiveness level, Glascow coma score, and outcome. Percentages of airway interventions more than tripled from previous reports from the wars in Afghanistan and Iraq. These changes are significant and further study is needed to determine the causes. Casualties requiring airway interventions sustained more severe injuries and experienced lower survival than patients who did not undergo an airway procedure, findings suggested in previous reports. Level III, prognostic and epidemiological.

A self-completed questionnaire study of attitudes and perceptions of paramedic and prehospital practitioners towards acute seizure care in Northern Ireland.

Abstract: Paramedics are increasingly expected to take on wider roles in the management of epilepsy in the community by making nonconveyance decisions after patients have had seizures. Studies have identified barriers to the successful implementation of this clinical role. We sought to determine levels of confidence, training, perceived barriers, and self-identified learning needs and methods to address these needs regarding seizure management. A questionnaire was developed by consensus and administered to 63 paramedic and prehospital clinicians at various mandatory training days occurring at the central headquarters of the regional ambulance service in Northern Ireland. Participants had no foreknowledge of the questionnaire, which was self-completed and returned immediately. A 75% return rate was obtained after 63 questionnaires were distributed. Paramedics had a mean of 11.5years of experiences, and 49% had treated 1-10 seizures in the last year. The Joint Royal Colleges Ambulance Liaison Committee guideline on seizure management is the most commonly utilized clinical guideline (100%). All could recall formal training on seizures in their qualification course. They identified a need to develop their knowledge in certain aspects of drug management and seizure subtype identification, including nonepileptic attack disorder (NEAD). Seventy percent of paramedics had a limited understanding of NEAD. Overall, paramedics rated their confidence as higher in drug treatment and the process of managing a seizure but rated their confidence lower in recognizing different seizure types as well as making nonconveyance decisions. The two factors which were cited as instilling high confidence included clinical experience and good use of provided protocols. Other barriers identified included lack of access to intramuscular midazolam, poor information availability in the prehospital setting, and a lack of a feedback mechanism to ensure follow-up. The methods by which learning needs would be addressed included tutorials, e-Learning, and simulation, with 30% preferring a combination of these methods. We identified that the paramedic workforce feels a reasonable to high level of confidence in the management of acute seizures. However, there are areas where they experience less confidence including making nonconveyance decisions and the identification of nontonic-clonic seizure subtypes. Copyright © 2017 Elsevier Inc.

The dead and the dying - a difficult part of EMS transport: A Swiss cross-sectional study.

Abstract: Most deaths occur in the pre-hospital setting, whereas mortality in the emergency department (ED) is low (<1%). However, our clinical impression is that some patients are being transported to hospital in devastating conditions with no likelihood of survival, but demanding extensive hospital resources. The decision on whether to transport a dying person to hospital or not is a difficult task for emergency medical services (EMS) personnel. As there is little epidemiological data about these patients, this paper aims to describe this special population. Retrospective cross-sectional study on adult patients transported by ground ambulance to the ED of a Swiss university hospital, who died during their stay in the ED between January 2008 and December 2012. Data was collected on the basis of ambulance report forms and discharge summaries of the ED. One hundred and sixty-one patients were analysed. Most deaths were due to cardiovascular diseases (43%). Only 9% of patients died of trauma. The median age was 70 years (IQR 56-81 years) and 70% (n = 112) were men. Trauma patients were significantly younger (median age 55 years, p<0.001). The overall mortality rate was 0.9% for all patients transported by EMS to the ED. About one third of all patients received cardiopulmonary resuscitation (CPR) from bystanders (n = 53). The most common electrocardiogram (ECG) findings were asystole (n = 57) and pulseless electrical activity (n = 91). Fifty percent (n = 64) of the resuscitated patients were defibrillated. Three quarters (n = 115, 72%) of all patients were intubated on site. The mechanical chest compression device Lucas™2 was mainly used in cases of cardiovascular or uncertain cause of death and did not reduce the operating time on site. The low ED mortality rate of 0.9% shows that only a few dying patients are transported to hospital. However, transport to hospital has to be carefully evaluated, especially for elderly patients with asystole or PEA due to medical conditions. The low CPR rate from bystanders demonstrates that public CPR training should be promoted further. The use of Lucas™2 did not reduce the operating time on site. For further investigations, comparison with survivors would be needed.

Helicopter vs. ground transportation of patients bound for primary percutaneous coronary intervention

Abstract: Implementation of the first Danish helicopter emergency medical service (HEMS) was associated with reduced time from first medical contact to treatment at a specialized centre for patients with suspected ST elevation myocardial infarction (STEMI). We aimed to investigate effects of HEMS on mortality and labour market affiliation in patients admitted for primary percutaneous coronary intervention (PCI).In this prospective observational study, we included patients with suspected STEMI within the region covered by the HEMS from January 1, 2010, to April 30, 2013, transported by either HEMS or ground emergency medical services (GEMS) to the regional PCI centre. The primary outcome was 30-day mortality.Among the 384 HEMS and 1220 GEMS patients, time from diagnostic ECG to PCI centre arrival was lower with HEMS (median 71 min vs. 78 min with GEMS; P = 0.004). Thirty-day mortality was 5.0% and 6.2%, respectively (adjusted OR = 0.82, 95% CI 0.44–1.51, P = 0.52. Involuntary early retirement rates were 0.62 (HEMS) and 0.94 (GEMS) per 100 PYR (adjusted IRR = 0.68, 0.15–3.23, P = 0.63). The proportion of patients on social transfer payments longer than half of the follow-up time was 22.1% (HEMS) vs. 21.2% (adjusted OR = 1.10, 0.64–1.90, P = 0.73).In an observational study of patients with suspected STEMI in eastern Denmark, no significant beneficial effect of helicopter transport could be detected on mortality, premature labour market exit or work ability. Only a study with random allocation to one system vs. another, along with a large sample size, will allow determination of superiority of helicopter transport.

Review article: Managing medical emergencies in rural Australia: A systematic review of the training needs

Abstract: The aim of the study was to determine the training needs of doctors managing emergencies in rural and remote Australia. A systematic review of Australian articles was performed using MEDLINE (OVID) and INFORMIT online databases from 1990 to 2016. The search terms included ‘Rural Health’, ‘Emergency Medicine’, ‘Emergency Medical Services’, ‘Education, Medical, Continuing’ and ‘Family Practice’. Only peer-reviewed articles, available in full-text that focussed on the training needs of rural doctors were reviewed. Data was extracted using pre-defined fields such as date of data collection, number of participants, characteristics of participants, location and study findings. A total of eight studies published from 1998 to 2006 were found to be suitable for inclusion in the analysis. Six studies cited the results of self-reported questionnaires and surveys, one used a telephone questionnaire on a hypothetical patient and one utilised a theoretical examination. The studies found a significant proportion of participants wanted more emergency training. Junior rural doctors were found to have deficiencies in knowledge about stroke. Emergency skills doctors wanted more training including: emergency ultrasound, paediatric/neonatal procedures and cricothyroidotomy. However, many of the studies were performed by training providers that may benefit from deficient results. Given that the data was over 10 years old and that advances have been made in knowledge, training opportunities and technology, the implications for current training needs of rural doctors in Australia could not be accurately assessed. Thus there is a need for further research to identify current training needs.

How many patients could benefit from REBOA in prehospital care? A retrospective study of patients rescued by the doctors of the Paris fire brigade.

Abstract: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a technique to control haemorrhage by placing a retrograde catheter in an artery and inflating a balloon at its tip. This retrospective study aimed to evaluate the proportion of injured people who could potentially have benefited from this technique prior to hospitalisation, including on the scene or during transport. A retrospective analysis was conducted of all patients with trauma registered in the Paris Fire Brigade emergency medical system between 1 January and 31 December 2014. Inclusion criteria included all patients over 18 years of age with bleeding of supposedly abdominal and/or pelvic and/or junctional origin, uncontrolled haemorrhagic shock or cardiac arrest with attempted resuscitation. During this study period, a total of 1159 patients with trauma (3.2%) would have been eligible to undergo REBOA. Death on scene rate was 83.8% (n=31) and six patients had a beating heart when they arrived at the hospital. Ten out of the 37 patients had spontaneous circulatory activity. Among them, four people died on the scene or during transport. Thirty-six out of 37 patients were intubated, one benefited from the use of a haemostatic dressing and one benefited from a tourniquet. REBOA can be seen as an effective non-surgical solution to ensure complete haemostasis during the prehospital setting. When comparing the high mortality rate following haemorrhage with the REBOA's rare side effects, the risk-benefit balance is positive. Given that 3% of all patients with trauma based on this study would have been eligible for REBOA, we believe that this intervention should be available in the prehospital setting. The results of this study will be used: educational models for REBOA balloon placement using training manikins, with an ultimate aim to undertake a prospective feasibility study in the prehospital setting. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Promoting collaboration in emergency medicine

Abstract: Collaborative practice between paramedics and medical staff is essential for ensuring the safe handover of patients. Handover of care is a critical time in the patient journey, when effective communication and collaborative practice are central to promoting patient safety and to avoiding medical error. To encourage effective collaboration between paramedic and medical students, an innovative, practice-based simulation exercise, known as interprofessional clinical skills (ICS) was developed at the University of East Anglia, UK. Emphasising patient safety, effective handover of care and teamwork, within the context of emergency medicine, the ICS promotes collaborative practice amongst health care students through the use of high- and low-fidelity simulation, human factors and values-based practice. A total of 123 undergraduate students from paramedic (60) and medical backgrounds (63) took part in the ICS. Evaluation data were collected from all students through the completion of an internal feedback/satisfaction questionnaire with 13 statements and one open-ended comment box.The response rate for the questionnaire was 100%. Of the 123 students from paramedic and medical disciplines, 99% agreed or strongly agreed with the statement ‘I enjoyed this session’. Students also felt that the ICS helped them to build mutual respect (98%), enhance understanding of roles (94%) and develop as collaborative practitioners (92%).Collaborative practice between paramedics and medical staff is essentialThe ICS is an innovative, enjoyable and meaningful intervention for promoting interprofessional collaborative practice between paramedic and medical students in a simulated practice setting. It encourages students to gain core training in clinical skills and patient safety, within a safe, supervised environment.

Prehospital Interventions Performed on Pediatric Trauma Patients in Iraq and Afghanistan.

Abstract: United States (US) and coalition military medical units deployed to combat zones frequently encounter pediatric trauma patients. Pediatric patients may present unique challenges due to their anatomical and physiological characteristics and most military prehospital providers lack pediatric-specific training. A minimal amount of data exists to illuminate the prehospital care of pediatric patients in this environment. We describe the prehospital care of pediatric trauma patients in Iraq and Afghanistan. We queried the Department of Defense Trauma Registry (DODTR) for all pediatric subjects admitted to US and Coalition fixed-facility hospitals in Iraq and Afghanistan from January 2007 to January 2016. Subjects were grouped by age: <1, 1-4, 5-9, 10-14, and 15-17 years. We focused our analysis on interventions related to trauma resuscitation. Of 42,790 encounters in the DODTR during the study period, 3,439 (8.0%) were aged <18 years. Most subjects were in the 5-9 age group (33.1%), male (77.1%), located in Afghanistan (67.8%), injured by explosives (43.1%). Most subjects survived to hospital discharge (90.2%). The most frequently performed interventions were tourniquet placement (6.6%), intubation (6.1%), supplemental oxygen (11.7%), IV access (24.8%), IV fluids (13.3%), IO access (5.1%), and hypothermia prevention (44.5%). The most frequently administered medications were antibiotics (6.2%) and opioids (15.0%). Most procedural and medication interventions occurred in subjects injured by explosives (43.1%) and gunshot wounds (22.1%). Pediatric subjects comprised over 1 in 13 casualties treated in the joint theaters with the majority injured by explosives. Vascular access and hypothermia prevention interventions were the most frequently performed procedures. Key words: prehospital; pediatric; combat; trauma; military.

Public awareness of the need to call emergency medical services following the onset of acute myocardial infarction and associated factors in Japan.

Abstract: Objectives Early recognition of acute myocardial infarction (AMI) and early activation of emergency medical services (EMS) are essential to reduce delays in patient care. We investigated public awareness of the need to call EMS at onset of AMI and evaluated associated factors. Methods In January 2008, a nationwide population-based survey using quota sampling was conducted in Japan. The primary outcome measure was responsiveness to promptly calling EMS at AMI onset, subdivided by on-time (daytime) and off-time (nights and holidays) hours. Results In total, 1200 participants were surveyed. Their mean age was 46.3 years (standard deviation, 17.4), and 50.3% (n=604) were women. A total of 11.6% (n=139) answered that they would call EMS during on-time hours, and 27.5% (n=330) stated that they would call during off-time hours. Multivariable analysis showed that the participants' age, female sex, education level, and self-confidence regarding their understanding of AMI were significant associated factors. The associated factors were almost identical during the off-time hours; only sex was no longer significant. Conclusions Public awareness of the need to call EMS at AMI onset in Japan was low. Previous intervention studies that were not effective may not have targeted groups with significant risk factors.

Simulation of the Effects of Co-Locating Naloxone with Automated External Defibrillators.

Abstract: Opioid-related overdoses have been steadily increasing over the past decade in the United States. Naloxone is used by first responders to revive overdose victims, but results may be improved by increasing access to and usage of naloxone by bystanders. Automated External Defibrillators (AEDs) are pervasive, recognizable, and publicly accessible. Co-locating naloxone kits with AEDs could increase public naloxone access and usage. However, the impact of co-locating naloxone kits with AEDs is not known. We sought to evaluate the impact of co-locating naloxone kits with AEDs in a simulation study centered on Allegheny County, Pennsylvania. Naloxone administration frequency (N = 3,650) at the zip-code level from March 2016 to March 2017 was provided by the Allegheny County Health Department. AED point locations (N = 1,653) were obtained from the University of Pittsburgh's Resuscitation Logistics and Informatics Venture. Zip-code level geospatial analyses were conducted using QGIS and STATA to determine the correlation between AED count and naloxone administrations. AED naloxone kit (N-AED) coverage, based on a maximum "walking-distance" radius of 200 m, was estimated at a zip-code level using the QGIS buffer tool and a custom MATLAB script. Potential impact of N-AEDs was estimated assuming uniform spatial distribution of naloxone administrations. The median (IQR) AED coverage based on a 200 m access radius per zip code was 4% (0-7). The median (IQR) number of naloxone administrations per zip code was 27(7-55). A total of 82 zip codes had data for both AED locations and naloxone administrations. The correlation between number of AEDs and naloxone administrations per zip code was 0.20. Overall, 16% of naloxone administrations were estimated to be covered by an N-AED. Using these limited methods, co-locating naloxone with AEDs is not likely to have a standalone impact on preventing overdose fatalities.

Prehospital Advanced Diagnostics and Treatment of Acute Stroke: Protocol for a Controlled Intervention Study.

Abstract: Acute ischemic stroke (AIS) is a medical emergency. The outcome is closely linked to the time elapsing from symptom onset to treatment, and seemingly small delays can mean the difference between full recovery and physical and cognitive dysfunction. Recanalization to allow blood to reenter the affected area is most efficient immediately after symptoms occur, and intravenous thrombolysis must be initiated no later than 4.5 hours after the symptom onset. A liable diagnosis is mandatory to administer the appropriate treatment. Prehospital diagnosis and, in cases where contraindications are ruled out, prehospital initiation of intravenous thrombolysis have been shown to significantly decrease the time from alarm to the treatment. The objective of this paper is to investigate the effectiveness of prehospital thrombolysis as measured by (1) time spent from symptom onset to treatment and (2) the number of patients treated within 4.5 hours. In addition, we want to conduct explorative studies. These will include (1) the use of biomarkers for diagnostic and prognostic use where we will collect blood samples from various time points, including the hyperacute phase and (2) the study of magnetic resonance imaging (MRI) images at day 1 to determine the infarct volume and if the time to thrombolysis has an influence on this. This is a prospective controlled intervention study. The intervention will involve a computed tomography (CT) and thrombolysis in a physician-manned ambulance called a mobile stroke unit (MSU). The control will be the conventional pathway where the patient is transported to the hospital for CT, and thrombolysis as per current procedure. Patient inclusion has started and a total of 37 patients are enrolled (control and intervention combined). The estimated time to completed inclusion is 36 months, starting from May 2017. The results of this study will be analyzed and published at the end of the trial. This trial aims to document the feasibility of saving time for all stroke patients by providing prehospital diagnostics and treatment, as well as transport to appropriate level of care, in a safe environment provided by anesthesiologists trained in prehospital critical care.

The mechanism of blood flow during chest compressions for cardiac arrest is probably influenced by the patient's chest configuration

Abstract: Mechanical assist devices are sometimes needed during resuscitation efforts of patients with prolonged cardiac arrest. Two such devices, the AutoPulse and the LUCAS, have different mechanisms of action. We propose that the effectiveness of mechanical assist devices is somewhat dependent on the configuration and compliance of the patient's chest wall.A previous study of patients with out-of-hospital cardiac arrest in Arizona reported that survivors were younger and many were observed to have narrow anterior–posterior chest diameters. These observations suggest that the predominant mechanism of blood flow during cardiopulmonary resuscitation of individuals with primary cardiac arrest is influenced by the patient's anterior–posterior chest diameter and compliance. It is proposed that in older individuals with an increased anterior–posterior chest diameter and decreased chest compliance that the AutoPulse, which works by increasing intrathoracic pressures, may be more effective. In contrast, the LUCAS device, which works predominately by compression of the sternum, is probably more effective in patients with narrower anterior–posterior diameters and a more compliant chest.These hypotheses need to be confirmed by researchers who not only have access to the lateral chest roentgenograms of patients with cardiac arrest, to determine their anterior–posterior chest diameter, but also to the type of mechanical device that was used during resuscitation efforts and their patient's survival. If the observations herein proposed are confirmed, hospitals and paramedics may ideally need to have one of each type of mechanical chest compression unit and select the one to use depending on the patient's age and anterior–posterior chest diameter.The mechanism of blood flow in patients with cardiac arrest is predominantly secondary to cardiac compression in younger patients with narrow anterior chest diameters and predominately secondary to the thoracic pump mechanism in older patients with emphysema.

Evolution And Organization Of Trauma Systems

Abstract: Publication date: Available online 21 February 2018 Source:Anaesthesia Critical Care & Pain Medicine Author(s): Jean Stéphane David, Pierre Bouzat, Mathieu Raux Over the last 20 years, numerous studies have fairly consistently reported an improvement in the prognosis of patients with severe trauma after the establishment of a trauma network. These systems can be either exclusive, in which all patients are referred only to a small number of specifically designated centres that meet strict criteria, or inclusive, in which patients may be referred to any hospital of a particular area according to capacity, which is observed in France. Hospitals are classified (level 1 to level 3) according to their technical facilities and the number of patients admitted for severe trauma, knowing that studies have also shown an improvement of the outcome for the most severely injured patients (haemorrhagic shock, severe head trauma), in hospitals with the greatest technical facilities and the most important activity. The triage of the patients to a suitable centre must be done after careful prehospital evaluation, which is made on clinical criteria (mechanism, injury, medical history), measurement of vital signs, calculation of scores (RTS, MGAP) or based on classifications. According to this assessment, the patients will then be triaged to a centre that has the capacity for the optimal and definitive management of these injuries. The goal is then to avoid under triage which is synonymous of retransfer, loss of time, and probably also prognosis worsening, and to avoid over triage that may induce an inadequate use of resources, activity overload and cost increase. Thus, it seems essential to develop trauma networks to improve mortality and morbidity of patients that undergone a severe injury. These trauma networks will then have to be evaluated and a register set up.

Prehospital quick sequential organ failure assessment as a tool to predict in-hospital mortality

Abstract: Publication date: Available online 10 February 2018 Source:The American Journal of Emergency Medicine Author(s): Kyohei Miyamoto, Naoaki Shibata, Tsuyoshi Nakashima, Seiya Kato Objective This study aimed to evaluate the predictive ability of quick sequential organ failure assessment (qSOFA) score for in-hospital mortality among patients transported by physician-staffed helicopters. Methods We conducted a single-center, retrospective observational study using the physician-staffed helicopter registry data between 2003 and 2016. We calculated the qSOFA scores based on the patients' vital signs, which were measured on the scene. The tool's discriminatory ability was determined using the area under the curve of the receiver operating characteristic. Results A total of 1849 patients with a mean age of 63.0 (standard deviation [SD], 18.4) years were included in this study. The diagnostic categories included were trauma and nontrauma cases (1038 [56%] and 811 [44%], respectively). In-hospital mortality was documented in 169 (9%) patients. Meanwhile, the in-hospital mortality rates among patients with qSOFA scores of 0, 1, 2, and 3 were 5/411 (1%), 69/797 (9%), 71/541 (13%), and 24/100 (24%), respectively (P < 0.0001 for trend). If the cutoff point is ≥1, the sensitivity and specificity of the qSOFA scores were 0.97 and 0.24, respectively. The area under the curve of the qSOFA scores was 0.67 for all patients, whereas that for trauma patients was 0.75. Conclusion An increase in the qSOFA score is associated with a gradual increase in the in-hospital mortality rate among all patients. In particular, a very low mortality rate was observed among patients with a qSOFA score of 0. The qSOFA score predicted the in-hospital mortality of patients with trauma well.

Pre-Hospital Education in Triage for Pediatric and Pregnant Patients in a Regional Trauma System without Collocated Pediatric and Adult Trauma Centers

Abstract: Publication date: Available online 11 February 2018 Source:Journal of Pediatric Surgery Author(s): Sarah B Cairo, Malachi Fisher, Brian Clemency, Charlotte Cipparone, Evelyn Quist, Kathryn D Bass Purpose Patient triage to the appropriate destination is critical to prehospital trauma care. Triage decisions are challenging in a region without co-located pediatric and adult trauma centers. Methods A regional survey was administered to emergency medical response units identifying variability and confusion regarding factors influencing patient disposition. A course was developed to guide the triage of pediatric and pregnant trauma patients. A pre- and post-test were administered to address course principles, including decision making and triage. Results A total of 445 participants completed the course at 22 sites representing 88 different prehospital provider agencies. Pre- and post-tests were administered to 62% of participants with an average score improvement of 53.4% (pre-test range 30% to 56.6%; post-test range 85% to 100%). Improvements were seen in all categories including major and minor trauma in pregnancy, major trauma in adolescence, and knowledge of age limits and triage protocols. Conclusion Education on triage guidelines and principles of pediatric resuscitation are essential for appropriate pre-hospital trauma management. Pre- and post-tests may be used to demonstrate short term efficacy, while ongoing evaluations of practice patterns and follow-up surveys are needed to demonstrate longevity of acquired knowledge and identify areas of persistent confusion.

Evaluation of Change in Knowledge and Attitude of Emergency Medicine Residents after Introduction of a Rotation in Emergency Medical Services and Disaster Medicine

Abstract: Nawfal Aljerian, Aamir Omair, Sami A Yousif, Abdulrahman S Alqahtani, Faisal A Alhusain, Bader Alotaibi, Mohammad F Alshehri, Majed Aljuhani, Saad Albaiz, Yasser Alaska, Abdullah F Alanazi Journal of Emergencies, Trauma, and Shock 2018 11(1):42-46 Background: Saudi Board of Emergency Medicine (SBEM) graduates are involved in a 1-month rotation in emergency medical services (EMSs) and disaster medicine. The purpose of this study was to evaluate change in knowledge and attitude of EM residents after the introduction of the EMS and disaster medicine rotation. Materials and Methods: The study included 32 3rd-year SBEM residents. A pretest/posttest design and a five-point Likert scale were used. The data included a response to a questionnaire developed by EMS and disaster experts. The questionnaire was distributed on the 1st day of the rotation and 45 days after. Satisfaction questionnaires were distributed after the rotation. The data were analyzed using SPSS 20. Results: Twenty-five residents responded to the satisfaction survey (75%). The overall satisfaction with the course modules was high; the course content showed the highest level of satisfaction (96%), and the lowest satisfaction was for the air ambulance ride outs (56%). The results of the pre-/post-test questionnaire showed an increase of 18.5% in the residents mean score (P < 0.001). In the open-ended section, the residents requested that the schedule is distributed before the course start date, to have more field and hands-on experience, and to present actual disaster incidents as discussion cases. The residents were impressed with the organization and diversity of the lectures, and to a lesser extent for the ambulance ride outs and the mass casualty incident drill l. Seventy-one percent indicated that they would recommend this course to other residents. Conclusion/Recommendation: This study showed that a structured course in EMS and disaster medicine had improved knowledge and had an overall high level of satisfaction among the residents of the SBEM. Although overall satisfaction and improvement in knowledge were significant, there are many areas in need of better organization.
