RESUMEN
The benefits of a telemedical support system for prehospital emergency medical services include high-level emergency medical support at the push of a button: delegation of drug administration, diagnostic assistance, initiation of therapeutic measures, or choice of hospital destination. At various European EMS sites telemedical routine systems are shortly before implementation. The aim of this study was to investigate the long-term effects of implementing a tele-EMS system on the structural and procedural quality indicators and therefore performance of an entire EMS system. This retrospective study included all EMS missions in Aachen city between 2015 and 2021. Regarding structural indicators of the EMS system, we investigated the overall number of emergency missions with tele-EMS and onsite EMS physicians. Furthermore, we analyzed the distribution of tracer diagnosis and process quality with respect to the time spans on the scene, time until teleconsultation, duration of teleconsultation, prehospital engagement time, and number of simultaneous teleconsultations. During the 7-year study period, 229,384 EMS missions were completed. From 2015 to 2021, the total number of EMS missions increased by 8.5%. A tele-EMS physician was consulted on 23,172 (10.1%) missions. The proportion of telemedicine missions increased from 8.6% in 2015 to 12.9% in 2021. Teleconsultations for missions with tracer diagnoses decreased during from 43.7% to 30.7%, and the proportion of non-tracer diagnoses increased from 56.3% to 69.3%. The call duration for teleconsultation decreased from 12.07 min in 2015 to 9.42 min in 2021. For every fourth mission, one or more simultaneous teleconsultations were conducted by the tele-EMS physician on duty. The implementation and routine use of a tele-EMS system increased the availability of onsite EMS physicians and enabled immediate onsite support for paramedics. Parallel teleconsultations, reduction in call duration, and increase in ambulatory onsite treatments over the years demonstrate the increasing experience of paramedics and tele-EMS physicians with the system in place. A prehospital tele-EMS system is important for mitigating the current challenges in the prehospital emergency care sector.

CURRENT STATUS OF EMERGENCY MEDICINE IN GERMANY: Increasing numbers of rescue missions in recent years have led to a growing staff shortage of paramedics as well as physicians in the emergency medical system (EMS) with an urgent need for optimized usage of resources. One option is the implementation of a tele-EMS physician system, which has been established in the EMS of the City of Aachen since 2014. IMPLEMENTATION OF TELE-EMERGENCY MEDICINE: In addition to pilot projects, political decisions lead to the introduction of tele-emergency medicine. The expansion is currently progressing in various federal states, and a comprehensive introduction has been decided for North Rhine-Westphalia and Bavaria. The adaptation of the EMS physician catalog of indications is essential for the integration of a tele-EMS physician. STATUS QUO OF TELE-EMERGENCY MEDICINE: The tele-EMS physician offers the possibility of a long-term and comprehensive EMS physician expertise in the EMS regardless of location and, therefore, to partially compensate for a lack of EMS physicians. Tele-EMS physicians can also support the dispatch center in an advisory capacity and, for example, clarify secondary transport. A uniform qualification curriculum for tele-EMS physicians was introduced by the North Rhine and Westphalia-Lippe Medical Associations. OUTLOOK: In addition to consultations from emergency missions, tele-emergency medicine can also be used for innovative educational applications, for example, in the supervision of young physicians or recertification of EMS staff. A lack of ambulances could be compensated for by a community emergency paramedic, who could also be connected to the tele-EMS physician.

BACKGROUND: A tele-emergency medical service with a remote emergency physician for severe prehospital emergencies may overcome the increasing number of emergency calls and shortage of emergency medical service providers. We analysed whether routine use of a tele-emergency medical service is non-inferior to a conventional physician-based one in the occurrence of intervention-related adverse events. METHODS: This open-label, randomised, controlled, parallel-group, non-inferiority trial included all routine severe emergency patients aged ≥ 18 years within the ground-based ambulance service of Aachen, Germany. Patients were randomised in a 1:1 allocation ratio to receive either tele-emergency medical service (n = 1764) or conventional physician-based emergency medical service (n = 1767). The primary outcome was the occurrence of intervention-related adverse events with suspected causality to the group assignment. The trial was registered with ClinicalTrials.gov (NCT02617875) on 30 November 2015 and is reported in accordance with the CONSORT statement for non-inferiority trials. RESULTS: Among 3531 randomised patients, 3220 were included in the primary analysis (mean age, 61.3 years; 53.8% female); 1676 were randomised to the conventional physician-based emergency medical service (control) group and 1544 to the tele-emergency medical service group. A physician was not deemed necessary in 108 of 1676 cases (6.4%) and 893 of 1544 cases (57.8%) in the control and tele-emergency medical service groups, respectively. The primary endpoint occurred only once in the tele-emergency medical service group. The Newcombe hybrid score method confirmed the non-inferiority of the tele-emergency medical service, as the non-inferiority margin of - 0.015 was not covered by the 97.5% confidence interval of - 0.0046 to 0.0025. CONCLUSIONS: Among severe emergency cases, tele-emergency medical service was non-inferior to conventional physician-based emergency medical service in terms of the occurrence of adverse events.

BACKGROUND: Systems thinking can be used as a participatory data collection and analysis tool to understand complex implementation contexts and their dynamics with interventions, and it can support the selection of tailored and effective implementation actions. A few previous studies have applied systems thinking methods, mainly causal loop diagrams, to prioritize interventions and to illustrate the respective implementation context. The present study aimed to explore how systems thinking methods can help decision-makers (1) understand locally specific causes and effects of a key issue and how they are interlinked, (2) identify the most relevant interventions and best fit in the system, and (3) prioritize potential interventions and contextually analyse the system and potential interventions. METHODS: A case study approach was adopted in a regional emergency medical services (EMS) system in Germany. We applied systems thinking methods following three steps: (1) a causal loop diagram (CLD) with causes and effects (variables) of the key issue "rising EMS demand" was developed together with local decision-makers; (2) targeted interventions addressing the key issue were determined, and impacts and delays were used to identify best intervention variables to determine the system's best fit for implementation; (3) based on steps 1 and 2, interventions were prioritized and, based on a pathway analysis related to a sample intervention, contextually analysed. RESULTS: Thirty-seven variables were identified in the CLD. All of them, except for the key issue, relate to one of five interlinked subsystems. Five variables were identified as best fit for implementing three potential interventions. Based on predicted implementation difficulty and effect, as well as delays and best intervention variables, interventions were prioritized. The pathway analysis on the example of implementing a standardized structured triage tool highlighted certain contextual factors (e.g. relevant stakeholders, organizations), delays and related feedback loops (e.g. staff resource finiteness) that help decision-makers to tailor the implementation. CONCLUSIONS: Systems thinking methods can be used by local decision-makers to understand their local implementation context and assess its influence and dynamic connections to the implementation of a particular intervention, allowing them to develop tailored implementation and monitoring strategies.

Background: The NEXUS-low-risk criteria (NEXUS) and Canadian C-spine rule (CSR) are clinical decision tools used for the prehospital spinal clearance in trauma patients, intending to prevent over- as well as under immobilization. Since 2014, a holistic telemedicine system is part of the emergency medical service (EMS) in Aachen (Germany). This study aims to examine whether the decisions to immobilize or not by EMS- and tele-EMS physicians are based on NEXUS and the CSR, as well as the guideline adherence concerning the choice of immobilization device. Methods: A single-site retrospective chart review was undertaken. Inclusion criteria were EMS physician and tele-EMS physician protocols with traumatic diagnoses. Matched pairs were formed, using age, sex and working diagnoses as matching criteria. The primary outcome parameters were the criteria documented as well as the immobilization device used. The evaluation of the decision to immobilize based on the criteria documented was defined as secondary outcome parameter. Results: Of a total of 247 patients, 34% (n = 84) were immobilized in the EMS physician group and 32.79% (n = 81) in the tele-EMS physician group. In both groups, less than 7% NEXUS or CSR criteria were documented completely. The decision to immobilize or not was appropriately implemented in 127 (51%) in the EMS-physician and in 135 (54, 66%) in the tele-EMS physician group. Immobilization without indication was performed significantly more often by tele-EMS physicians (6.88% vs 2.02%). A significantly better guideline adherence was found in the tele-EMS physician group, preferring the vacuum mattress (25, 1% vs 8.9%) over the spineboard. Conclusion: It could be shown that NEXUS and CSR are not applied regularly, and if so, mostly inconsistently with incomplete documentation by both EMS- and tele-EMS physicians. Regarding the choice of the immobilization device a higher guideline adherence was shown among the tele-EMS physicians.
RESUMEN
In the Emergency Medical Service Acts of the Federal States, the statements in these Acts have so far essentially been limited to the implementation of measures to maintain the health of emergency patients and to transport them to a suitable hospital. Preventive fire protection, on the other hand, is regulated in the Fire Brigade Acts or by statutory ordinances. Increasing numbers of emergency service missions and a lack of facilities for alternative care justify the need for a preventive emergency service. This includes all measures that take place before an event occurs in order to prevent emergencies from occurring. As a result, the risk of an emergency event leading to the emergency call 112 should be reduced or delayed. The preventive rescue service should also help to improve the outcome of medical care for patients. Furthermore, it should be made possible to provide those seeking help with a suitable form of care at an early stage.

BACKGROUND: Although respiratory distress is one of the most common complaints of patients requiring emergency medical services (EMS), there is a lack of evidence on important aspects. OBJECTIVES: Our study aims to determine the accuracy of EMS physician diagnostics in the out-of-hospital setting, identify examination findings that correlate with diagnoses, investigate hospital mortality, and identify mortality-associated predictors. METHODS: This retrospective observational study examined EMS encounters between December 2015 and May 2016 in the city of Aachen, Germany, in which an EMS physician was present at the scene. Adult patients were included if the EMS physician initially detected dyspnea, low oxygen saturation, or pathological auscultation findings at the scene (n = 719). The analyses were performed by linking out-of-hospital data to hospital records and using binary logistic regressions. RESULTS: The overall diagnostic accuracy was 69.9% (485/694). The highest diagnostic accuracies were observed in asthma (15/15; 100%), hypertensive crisis (28/33; 84.4%), and COPD exacerbation (114/138; 82.6%), lowest accuracies were observed in pneumonia (70/142; 49.3%), pulmonary embolism (8/18; 44.4%), and urinary tract infection (14/35; 40%). The overall hospital mortality rate was 13.8% (99/719). The highest hospital mortality rates were seen in pneumonia (44/142; 31%) and urinary tract infection (7/35; 20%). Identified risk factors for hospital mortality were metabolic acidosis in the initial blood gas analysis (odds ratio (OR) 11.84), the diagnosis of pneumonia (OR 3.22) reduced vigilance (OR 2.58), low oxygen saturation (OR 2.23), and increasing age (OR 1.03 by 1 year increase). CONCLUSIONS: Our data highlight the diagnostic uncertainties and high mortality in out-of-hospital emergency patients presenting with respiratory distress. Pneumonia was the most common and most frequently misdiagnosed cause and showed highest hospital mortality. The identified predictors could contribute to an early detection of patients at risk.

Background: In the Euregio-Meuse-Rhine (EMR), cross-border collaboration is essential for resource-saving and needs-based patient care within the emergency medical service (EMS) systems and interhospital transport (IHT). However, at the onset of the novel coronavirus SARS-COV-2 (COVID-19) pandemic, differing national measures highlighted the fragmentation within the European Union (EU) in its various approaches to combating the pandemic. To assess the consequences of the pandemic in the EMR border area, the aim of this study was to analyze the effects and "lessons learned" regarding cross-border collaboration in EMS and IHT. Method: A qualitative study with 22 semi-structured interviews was carried out. Experts from across the EMR area, including the City of Aachen, the City region of Aachen, the District of Heinsberg (Germany), South Limburg (The Netherlands), and the Province of Limburg, as well as Liège (Belgium), took part. The interviews were coded and analyzed according to changes in cross-border collaboration before and during the pandemic, as well as lessons learned and recommendations. Results: Each EU member country within the EMR area, addressed the pandemic individually with national measures. Cross-border collaboration between regional actors was hardly or not at all addressed at the national level during political decision- or policymaking. Previous direct communication at the personal level was replaced by national procedures, which made regular cross-border collaboration significantly more difficult. The cross-border transfer regulations of patients with COVID-19 proved to be complex and led, among other things, to patients being transported to hospitals far outside the border region. Collaboration continues to be seen as valuable and Euregional emergency services including hospitals work well together, albeit to different degrees. The information and data exchange should, however, be more transparent to use resources more efficiently. Conclusion: Effective Euregional collaboration of emergency services is imperative for public safety in a multi-border region with strong economic, cultural, and social cross-border links. Our findings indicate that existing (pre-pandemic) structures which included regular meetings of senior managerial staff in the region and a number of thematic working groups were helpful to deal with and to compensate for the disruptions during the crisis. Regional cross-border agreements that are currently based on mutual but more or less informal arrangements need to be formalized and better promoted and recognized also at the national and EU level to increase resilience. The continuous determination of synergies and good and best practices are further approaches to support cross-border collaboration especially in preparation for future crises.

BACKGROUND: Each year there are 7.3 million emergencies for the German rescue service, trend rising and around 59% of the emergency patients are treated by paramedics only; however, most of the studies focus on physicians, while their practical skills at the scene are rarely necessary. Accordingly, the responsibility for the patient lies with the paramedics most of the time. Their duty is to execute life-saving measures, stabilize the patient for the transport and the regular documentation of the operation. Retrospectively, the emergencies can only be analyzed based on the emergency protocols, which are mostly paper-based and handwritten. That causes an increased effort in the evaluation, which makes studies for the whole country hardly feasible. As of now there are only few data on quality of healthcare and documentation by the paramedics. Both were analyzed in this survey based on the emergency protocols. METHOD: A retrospective analysis of emergency protocols from June to July 2018 took place in Aachen, a major German city. A specific feature of Aachen is a 24h available emergency physician via telemedicine. The quality of documentation and healthcare was analyzed by including standard operating procedures. Primary endpoints were the frequency of documentation, the achievement of complete documentation, the correct indications for a physician, the development of critical vital signs and the average on-scene time of the ambulance. RESULTS: Overall, 1935 protocols were analyzed. A complete documentation was achieved in 1323 (68.4%) suspected diagnoses, 456 (23.6%) anamneses, 350 (18.1%) initial and 52 (2.7%) vital signs at handover. Based on the documentation, there were 531 cases (27%) of patients treated by paramedics only, even though a physician would have been indicated. Out of those patients 410 critical initial vital signs were documented of which 69 (16.8%) improved, while there was no documentation of vital signs at handover in 217 (52.9%). Also, there was a significantly prolonged on-scene time for patients with belated indications for an emergency physician with 15:02â¯min in comparison to 13:05â¯min for patients without indications. CONCLUSION: Deficient documentation was found in multiple cases and several important vital signs for a complete differential diagnosis were missing. Furthermore, a quarter of all patients might have benefited from an emergency physician as they were taken to hospital with no or insufficient treatment, despite standard operating procedures. From a forensic point of view there is an alarmingly incomplete documentation of vital signs at handover. The on-scene time in general was within the predetermined time frame, but can still be reduced in different scenarios. Overall, we recommend strict adherence to the standard operating procedures and algorithms, to remove unnecessary documentation and implement a structured quality assurance. Moreover, the quality of treatment might benefit from the rising number of more specialized paramedics and an increasing use of telemedicine.

BACKGROUND: Emergency training is designed to improve medical care teams' knowledge, practical skills, and treatment procedures in patient care to increase patient safety. This requires effective training, but the multifactorial effects of training are difficult to measure. METHODS: We assessed the impact of emergency team training on treatment procedures and quality, processes, technical skills, and nontechnical skills in simulated trauma emergencies in a longitudinal analysis, using videos that were recorded before (t0), immediately after (t1), and 1 year after the training (t2). The training was evaluated with the validated PERFECT checklist, which includes 7 scales: primary assessment, secondary assessment, procedures, technical skills, trauma communication, nontechnical skills, and a global performance scale.The primary end point was the change from before a training intervention (t0) to 1 year after training (t2), measured by a metric point score. The second end point was the impact of the intervention from before training to after and from immediately after training to 1 year later. RESULTS: A total of 146 trainings were evaluated. In simulated traumatological emergencies, training participants showed significantly better treatment capacity after 1 year (t0: 28.8 ± 5.6 points versus t2: 59.6 ± 6.6 points, P < 0.001), with greater improvement from t0 to t1 (28.8 ± 5.6 points versus 65.1 ± 7.9 points, P < 0.001). The most significant change from t0 to t2 was seen in the primary assessment, with a mean change of 11.1 ± 5.1, followed by the scale of the procedure (6.1 ± 3.0) and nontechnical skills (6.0 ± 3.0). CONCLUSIONS: Team trainings with intensive scenario training and short theoretical inputs lead to a significant improvement in simulated care of severely injured patients, especially in identifying and intervening in life-threatening symptoms, processes, and nontechnical skills, even 1 year after the course. Positive, longitudinally positive effects were also in communication and subjective safety of prehospital health care personnel.

OBJECTIVES: Interhospital transports of critically ill patients are high-risk medical interventions. Well-established parameters to quantify the quality of transports are currently lacking. We aimed to develop and cross-validate a score for interhospital transports. SETTING: An expert panel developed a score for interhospital transport by a Mobile Intensive Care Unit (MICU), the QUality of Interhospital Transportation in the Euregion Meuse-Rhine (QUIT-EMR) score. The QUIT-EMR score is an overall sum score that includes component scores of monitoring and intervention variables of the neurological (proxy for airway patency), respiratory and circulatory organ systems, ranging from -12 to +12. A score of 0 or higher defines an adequate transport. The QUIT-EMR score was tested to help to quantify the quality of transport. PARTICIPANTS: One hundred adult patients were randomly included and the transport charts were independently reviewed and classified as adequate or inadequate by four transport experts (ie, anaesthetists/intensivists). OUTCOME MEASURES: Subsequently, the level of agreement between the QUIT-EMR score and expert classification was calculated using Gwet's AC1. RESULTS: From April 2012 to May 2014, a total of 100 MICU transports were studied. The median (IQR) QUIT-EMR score was 1 (0-2). Experts classified six transports as inadequate. The percentage agreement between the QUIT-EMR score and experts' classification for adequate/inadequate transport ranged from 84% to 92% (Gwet's AC10.81-0.91). The interobserver agreement between experts was 87% to 94% (Gwet's AC10.89-0.98). CONCLUSION: The QUIT-EMR score is a novel validated tool to score MICU transportation adequacy in future studies contributing to quality control and improvement. TRIAL REGISTRATION NUMBER: NTR 4937.

Almost seven years ago, a telemedicine system was established as an additional component of the city of Aachen's emergency medical service (EMS). It allows paramedics to engage in an immediate consultation with an EMS physician at any time. The system is not meant to replace the EMS physician on the scene during life-threatening emergencies. The aim of this study was to analyze teleconsultations during life-threatening missions and evaluate whether they improve patient care. Telemedical EMS (tele-EMS) physician consultations that occurred over the course of four years were evaluated. Missions were classified as involving potentially life-threatening conditions based on at least one of the following criteria: documented patient severity score, life-threatening vital signs, the judgement of the onsite EMS physician involved in the mission, or definite life-threatening diagnoses. The proportion of vital signs indicating that the patient was in a life-threatening condition was analyzed as the primary outcome at the start and end of the tele-EMS consultation. The secondary outcome parameters were the administered drug doses, tracer diagnoses made by the onsite EMS physicians during the missions, and quality of the documentation of the missions. From January 2015 to December 2018, a total of 10,362 tele-EMS consultations occurred; in 4,293 (41.4%) of the missions, the patient was initially in a potentially life-threatening condition. Out of those, a total of 3,441 (80.2%) missions were performed without an EMS physician at the scene. Records of 2,007 patients revealed 2,234 life-threatening vital signs of which 1,465 (65.6%) were remedied during the teleconsultation. Significant improvement was detected for oxygen saturation, hypotonia, tachy- and bradycardia, vigilance states, and hypoglycemia. Teleconsultation during missions involving patients with life-threatening conditions can significantly improve those patients' vital signs. Many potentially life-threatening cases could be handled by a tele-EMS physician as they did not require any invasive interventions that needed to be performed by an onsite EMS physician. Diagnoses of myocardial infarction, cardiac pulmonary edema, or malignant dysrhythmias necessitate the presence of onsite EMS physicians. Even during missions involving patients with life-threatening conditions, teleconsultation was feasible and often accessed by the paramedics.

BACKGROUND: Teaching of resuscitation measures is not mandatory in all schools in Germany. It is currently limited to individual, partly mandatory projects despite a low bystander resuscitation rate. For this reason, the Ministry for Schools and Education of North Rhine-Westphalia initiated the project "Bystander resuscitation at schools in NRW" in March 2017. OBJECTIVE: The aim of this work was to evaluate this project. MATERIAL AND METHODS: All secondary schools in North Rhine-Westphalia were invited to participate in the project. Medical partners from each administrative district took part, who carried out resuscitation training with existing concepts for teacher or student training. After a 3-year period, the evaluation was carried out using standardized questionnaires for school headmasters, teachers and students. RESULTS: In total, more than 40,000 pupils from 249 schools in NRW could be trained in resuscitation within the project with 6 different concepts. Of the students 85% answered the questions regarding resuscitation correctly and overall felt safe in resuscitation measures. The one-off investment requirement for all schools is roughly 4-6.5â¯million⯠and around 340,000⯠in each budget year. CONCLUSION: A legal constitution and funding are necessary for a nationwide introduction of resuscitation in schools. All established concepts are effective, therefore each school can use them exactly according to their needs, optimally in a stepped form. Training for teachers should focus on resuscitation.

In 2014, a telemedicine system was established in 24-h routine use in the emergency medical service (EMS) of the city of Aachen. This study tested whether the diagnostic concordance of the tele-EMS physician reaches the same diagnostic concordance as the on-site-EMS physician. The initial prehospital diagnoses were compared to the final hospital diagnoses. Data were recorded retrospectively from the physicians' protocols as well as from the hospital administration system and compared. Also, all diagnostic misconcordance were analysed and reviewed in terms of logical content by two experts. There were no significant differences between the groups in terms of demographic data, such as age and gender, as well as regarding the hospital length of stay and mortality. There was no significant difference between the diagnostic concordance of the systems, except the diagnosis "epileptic seizure". Instead, in these cases, "stroke" was the most frequently chosen diagnosis. The diagnostic misconcordance "stroke" is not associated with any risks to patients' safety. Reasons for diagnostic misconcordance could be the short contact time to the patient during the teleconsultation, the lack of personal examination of the patient by the tele-EMS physician, and reversible symptoms that can mask the correct diagnosis.

Introduction: The focus of public attention and health policy is increasingly being drawn to patient safety. According to studies, more than 30,000 patients die each year as a result of medical errors. To date, learning objectives such as patient safety have not played a role in the core curriculum for medical education in Germany. The National Competence-Based Catalogue of Learning Objectives for Undergraduate Medical Education contains a total of 13 learning objectives relating to this subject. Methods: In a descriptive study, learning content was implemented within the "Operative Medicine" study block offered by the Faculty of Medicine at Universität Hamburg. The definition and occurrence of errors as well as strategies for dealing with and avoiding errors were set as the learning objectives for an interactive lecture, problem-based learning (PBL) case as well as the bedside teaching on anaesthesiology. Students were able to evaluate the lecture directly. During the simulator session on anaesthesia, the safety-relevant information that students requested from patients was compared with the questions asked by a control group in the previous trimester. Results: The topic of patient safety could be integrated into the "Operative Medicine" curriculum through a number of minor changes to classes. The accounts of personal experiences and importance assigned to the subject were considered positive, while content perceived as redundant was criticised. In the simulator, the students appeared to request more comprehensive preoperative safety-relevant information than the control group. Conclusion: The subject's relevance, positive feedback and trend towards a change in behaviour in the simulator lead the authors to deem introduction of the topic of patient safety a success.

INTRODUCTION: To increase the rate of bystander resuscitation, basic life support (BLS) training for schoolchildren is now recommended on a broad level. However, debate continues about the optimal teaching methods. In this study, we investigated the effects of a 90 min BLS training on female pupils' BLS knowledge and self-confidence and whether learning outcomes were influenced by the instructors' professional backgrounds or test-enhanced learning. METHODS: We conducted a cluster randomised, longitudinal trial in a girls' grammar school in Germany from 2013 to 2014. Pupils aged 10-17 years were randomised to receive BLS training conducted by either emergency physicians or medical students. Using a multiple-choice questionnaire and a Likert-type scale, BLS knowledge and self-confidence were investigated before training (t0), 1 week (t1) and 9 months after training (t2). To investigate whether test-enhanced learning influenced learning outcomes, the questionnaire was administered 6 months after the training in half of the classrooms. The data were analysed using linear mixed-effects models. RESULTS: The study included 460 schoolchildren. BLS knowledge (mean number of correct answers) increased from 5.86 at t0 to 9.24 at t1 (p<0.001) and self-confidence (mean score on the Likert-type scale) increased from 8.70 at t0 to 11.29 at t1 (p<0.001). After 9 months, knowledge retention was good (8.94 at t2; p=0.080 vs t1), but self-confidence significantly declined from t1 to 9.73 at t2 (p<0.001). Pupils trained by medical students showed a slight but statistically significant greater increase in the knowledge at both t1 and t2, whereas instructors' background did not influence gain or retention of self-confidence. Retesting resulted in a marginally, non-significantly better retention of knowledge. CONCLUSIONS: BLS training led to short-term gains in knowledge and self-confidence. Although knowledge was retained at 9 months after the training session, self-confidence significantly decreased. Interim testing did not appear to impact retention of knowledge or self-confidence. Medical students should be considered as instructors for these courses given their favourable learning outcomes and greater availability.

BACKGROUND: To treat many patients despite lacking personnel resources, triage is important in disaster medicine. Various triage algorithms help but often are used incorrectly or not at all. One potential problem-solving approach is to support triage with Smart Glasses. OBJECTIVE: In this study, augmented reality was used to display a triage algorithm and telemedicine assistance was enabled to compare the duration and quality of triage with a conventional one. METHODS: A specific Android app was designed for use with Smart Glasses, which added information in terms of augmented reality with two different methods-through the display of a triage algorithm in data glasses and a telemedical connection to a senior emergency physician realized by the integrated camera. A scenario was created (ie, randomized simulation study) in which 31 paramedics carried out a triage of 12 patients in 3 groups as follows: without technical support (control group), with a triage algorithm display, and with telemedical contact. RESULTS: A total of 362 assessments were performed. The accuracy in the control group was only 58%, but the assessments were quicker (on average 16.6 seconds). In contrast, an accuracy of 92% (P=.04) was achieved when using technical support by displaying the triage algorithm. This triaging took an average of 37.0 seconds. The triage group wearing data glasses and being telemedically connected achieved 90% accuracy (P=.01) in 35.0 seconds. CONCLUSIONS: Triage with data glasses required markedly more time. While only a tally was recorded in the control group, Smart Glasses led to digital capture of the triage results, which have many tactical advantages. We expect a high potential in the application of Smart Glasses in disaster scenarios when using telemedicine and augmented reality features to improve the quality of triage.

Health informatics applications reduce time intervals in acute coronary syndromes, but their impact on guideline adherence is unknown. This pre-post intervention study compared guideline adherence between telemedically supported (n = 101, April 2014-July 2015) and conventional on-scene care (n = 120, January 2014-March 2014) in acute coronary syndrome. A multivariate logistic regression was performed for dependent variables: adverse events 0 versus 0, p = NA; electrocardiogram 101 versus 120, p = NA; acetylic salicylic acid 91 versus 102, p = 0.21; heparin 92 versus 112, p = 0.99; morphine 96 versus 107, p = 0.33; oxygen 83 versus 102, p = 0.92; glyceroltrinitrate 55 versus 90, p = 0.038; correct destination: 100 versus 119, p = 1.0. The time from ambulance arrival to hospital arrival was prolonged with telemedicine: 48.7 ± 11 min versus 35.5 ± 8.1 min, p < 0.001. Guideline adherence showed no differences except for glyceroltrinitrate. Prolonged time requirements are critical, though explainable. However, this approach enables a timely and high-quality backup strategy if only paramedics are on-scene.
