- Abstract
Telemedicine as a communication technology to overcome geographical distances can increase the quality of medicine. The prerequisite for telemedicine is that two persons or groups of persons are connected with each other. Often this connection is built beforehand during a face-to-face-meeting when both partners apportion the communication devices. If an emergency patient is not already part of a telemedicine project, the connection has to be newly created and the device to build the connection has to be brought to the patient. In the EU-funded LiveCity-Project the hypothesis was evaluated, that in emergency situations a telemedicine connection between a patient and a remote medical doctor can be accomplished by a device brought to the patient by paramedics. It was to be established if communication with a head mounted video-camera coupled with a LTE internet connection was feasible for this purpose. © IFIP International Federation for Information Processing 2014.

- Abstract
Background: The prehospital placement of chest tubes is a rare but potentially life-saving procedure. A high level of subjective confidence with the procedure is essential for emergency medical doctors. This study aims to identify if there is a statistically significant difference in the subjective sense of confidence in prehospital chest tube placement regarding medical experience and qualification, clinical routine, and attendance at simulation courses., Methods: Prehospital emergency physicians of three emergency medical services in Southwest Saxony, Greifswald, and Vechta, Germany, were invited to participate in an online survey from January to March 2022 using the online survey service limesurvey. The question "Do you feel confident in chest tube placement?" was used to measure the subjective level of confidence. Answers were compared with data concerning medical qualification, experience in prehospital emergency medicine, clinical routine, and attendance at simulation courses. Statistical analysis was performed using chi-squared test and Fisher's exact test., Results: Three out of four participants felt confident in chest tube placement (53/71; 74.6%). More than half of the participants reported that they did not perform this procedure regularly (35/53, 66%). Subjective confidence was highest in physicians who regularly place chest tubes during their non-prehospital work (34/37; 91,9%; p<0.001), and more often when participants had clinical routine and attended simulation courses than when none of this applied (p=0.012). Attendance at simulation courses alone was not associated with a higher level of confidence (p=0.002). Specialists showed significantly more often subjective confidence in chest tube placement (p=0.0401)., Conclusion: Prehospital chest tube placement is rare, but potentially lifesaving. An adequately high level of subjective confidence in the placement of chest tubes is a key condition for prehospital emergency doctors. Inhospital clinical routine and attendance at simulation courses are significantly associated with high levels of confidence. Our data indicate that working only in prehospital emergency settings without further clinical routine or medical specialization is not sufficient for achieving and ensuring subjective confidence in chest tube placement., (Copyright © 2024.

- Abstract
Aim of the Study: Cardiac arrest research has not received as much scientific attention as research on other topics. Here, we aimed to identify cardiac arrest research barriers from the perspective of an international group of early career researchers., Methods: Attendees of the 2022 international masterclass on cardiac arrest registry research accompanied the Global Out-of-Hospital Cardiac Arrest Registry collaborative meeting in Utstein, Norway, and used an adapted hybrid nominal group technique to obtain a diverse and comprehensive perspective. Barriers were identified using a web-based questionnaire and discussed and ranked during an in-person follow-up meeting. After each response was discussed and clarified, barriers were categorized and ranked over two rounds. Each participant scored these from 1 (least significant) to 5 (most significant)., Results: Nine participants generated 36 responses, forming seven overall categories of cardiac arrest research barriers. "Allocated research time" was ranked first in both rounds. "Scientific environment", including appropriate mentorship and support systems, ranked second in the final ranking. "Resources", including funding and infrastructure, ranked third. "Access to and availability of cardiac arrest research data" was the fourth-ranked barrier. This included data from the cardiac arrest registries, medical devices, and clinical studies. Finally, "uniqueness" was the fifth-ranked barrier. This included ethical issues, patient recruitment challenges, and unique characteristics of cardiac arrest., Conclusion: By identifying cardiac arrest research barriers and suggesting solutions, this study may act as a tool for stakeholders to focus on helping early career researchers overcome these barriers, thus paving the road for future research., Competing Interests: The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: This research did not receive any specific grant from funding agencies in the public, commercial, or not-for-profit sectors.

- Abstract
Background: Cross-border cooperation of emergency medical services, institutions and hospitals helps to reduce negative impact of national borders and consecutive discrimination of persons living and working in border regions. This study aims to explore the feasibility and effectiveness of a cross-border bilingual simulation training for emergency medical services within an INTERREG-VA-funded project., Methods: Five days of simulation training for German and Polish paramedics in mixed groups were planned. Effectiveness of training and main learning objectives were evaluated as pre-post-comparisons and self-assessment by participants., Results: Due to COVID-19 pandemic, only three of nine training modules with n = 16 participants could be realised. Cross-border-simulation training was ranked more positively and was perceived as more useful after the training compared to pretraining. Primary survey has been performed using ABCDE scheme in 18 of 21 scenarios, whereas schemes to obtain medical history have been applied incompletely. However, participants stated to be able to communicate with patients and relatives in 10 of 21 scenarios., Conclusion: This study demonstrates feasibility of a bilingual cross-border simulation training for German and Polish rescue teams. Further research is highly needed to evaluate communication processes and intra-team interaction during bilingual simulation training and in cross-border emergency medical services rescue operations., (© 2023.

- Abstract
This study primarily aims to determine the frequency of life-threatening conditions among pediatric patients served by the DRF, a German helicopter emergency service (HEMS) provider. It also seeks to explore the necessity of invasive procedures in this population, discussing the implications for HEMS crew training and service configuration based on current literature. We analyzed the mission registry from 31 DRF helicopter bases in Germany, focusing on 7954 children aged 10 or younger over a 5-year period (2014-2018). Out of 7954 identified children (6.2% of all primary missions), 2081 (26.2%) had critical conditions. Endotracheal intubation was needed in 6.5% of cases, while alternative airway management methods were rare (n = 14). Half of the children required intravenous access, and 3.6% needed intraosseous access. Thoracostomy thoracentesis and sonography were only performed in isolated cases. Conclusions: Critically ill or injured children are infrequent in German HEMS operations. Our findings suggest that the likelihood of HEMS teams encountering such cases is remarkably low. Besides endotracheal intubation, life-saving invasive procedures are seldom necessary. Consequently, we conclude that on-the-job training and mission experience alone are insufficient for acquiring and maintaining the competencies needed to care for critically ill or injured children. What is Known: • Pediatric emergencies are relatively rare in the prehospital setting, but their incidence is higher in helicopter emergency medical services (HEMS) compared to ground-based emergency services. What is New: • On average, HEMS doctors in Germany encounter a critically ill or injured child approximately every 1.5 years in their practice, establish an IV or IO access in infants or toddlers every 2 years, and intubate an infant every 46 years. • This low frequency highlights the insufficiency of on-the-job training alone to develop and maintain pediatric skills among HEMS crews. Specific interdisciplinary training for HEMS crews is needed to ensure effective care for critically unwell pediatric patients., (© 2023. The Author(s).)

- Abstract
Aim of Study: This study aims to investigate feasibility and quality of a bilingual cardiopulmonary resuscitation training with interprofessional emergency teams from Germany and Poland., Methods: As part of a cross-border European Territorial Cooperation (Interreg-VA) funded project a combined communication and simulation training was organised. Teams of German and Polish emergency medicine personnel jointly practised resuscitation. The course was held in both languages with consecutive translation.Quality of chest compression was assessed using a simulator with feedback application. Learning objectives (quality of cardiopulmonary resuscitation, adherence to guidelines, closed loop communication), and team performance were assessed by an external observer. Coopeŕs Team Emergency Assessment Measure questionnaire was used., Results: Twenty-one scenarios with 17 participants were analysed. In all scenarios, defibrillation and medication were delivered with correct dosage and at the right time. Mean fraction of correct hand position was 85.7% ± 25.7 [95%-CI 74.0; 97.4], mean fraction of compression depth 75.1% ± 21.0 [95%-CI 65.6; 84.7], compression rate 117.7 min
-1 ± 7.1 [95%-CI 114.4; 120.9], and chest compression fraction 83.3% ± 3.8 [95%-CI 81.6; 85.0].Quality of cardiopulmonary resuscitation was rated as "fair" to "good", adherence to guidelines as "good", and closed loop communication as "fair". Bilingual teams demonstrated good situational awareness, but lack of leadership and suboptimal overall team performance., Conclusion: Bilingual and interprofessional cross-border resuscitation training in German and Polish tandem teams is feasible. It does not affect quality of technical skills such as high-quality chest compression but does affect performance of non-technical skills (e.g. closed loop communication and leadership)., Competing Interests: The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: The simulation training we are reporting about was funded by the European Union with-in the scope of Interreg VA -Mecklenburg-Vorpommern/Brandenburg/Pomerania., (© 2023 The Authors.)- Published

- Abstract
Background: Telephone-Cardiopulmonary Resuscitation (T-CPR) significantly increases rate of bystander resuscitation and improves patient outcomes after out-of-hospital cardiac arrest (OHCA). Nevertheless, securing correct execution of instructions remains a difficulty. ERC Guidelines 2021 recommend standardised instructions with continuous evaluation. Yet, there are no explicit recommendations on a standardised wording of T-CPR in the German language. We investigated, whether a modified wording regarding check for breathing in a German T-CPR protocol improved performance of T-CPR., Methods: A simulation study with 48 OHCA scenarios was conducted. In a non-randomised trial study lay rescuers were instructed using the real-life-CPR protocol of the regional dispatch centre and as the intervention a modified T-CPR protocol, including specific check for breathing (head tilt-chin lift instructions). Resuscitation parameters were assessed with a manikin and video recordings., Results: Check for breathing was performed by 64.3% (n = 14) of the lay rescuers with original wording and by 92.6% (n = 27) in the group with modified wording (p = 0.035). In the original wording group the head tilt-chin manoeuvre was executed by 0.0% of the lay rescuers compared to 70.3% in the group with modified wording (p < 0.001). The average duration of check for breathing was 1 ± 1 s in the original wording group and 4 ± 2 s in the group with modified wording (p < 0.001). Other instructions (e.g. check for consciousness and removal of clothing) were well performed and did not differ significantly between groups. Quality of chest compression did not differ significantly between groups, with the exception of mean chest compression depth, which was slightly deeper in the modified wording group., Conclusion: Correct check for breathing seems to be a problem for lay rescuers, which can be decreased by describing the assessment in more detail. Hence, T-CPR protocols should provide standardised explicit instructions on how to perform airway assessment. Each protocol should be evaluated for practicability., (© 2023. The Author(s).)

- Abstract
Background: Tele-emergency physicians (TEPs) take an increasingly important role in the need-oriented provision of emergency patient care. To improve emergency medicine in rural areas, we set up the project 'Rural|Rescue', which uses TEPs to restructure professional rescue services using information and communication technologies (ICTs) in order to reduce the therapy-free interval. Successful implementation of ICTs relies on user acceptance and knowledge sharing behavior., Method: We conducted a factorial design with active knowledge transfer and technology acceptance as a function of work satisfaction (high vs. low), workload (high vs. low) and point in time (prior to vs. after digitalization). Data were collected via machine readable questionnaires issued to 755 persons (411 pre, 344 post), of which 304 or 40.3% of these persons responded (194 pre, 115 post)., Results: Technology acceptance was higher after the implementation of TEP for nurses but not for other professions, and it was higher when the workload was high. Regarding active communication and knowledge sharing, employees with low work satisfaction are more likely to share their digital knowledge as compared to employees with high work satisfaction. This is an effect of previous knowledge concerning digitalization: After implementing the new technology, work satisfaction increased for the more experienced employees, but not for the less experienced ones., Conclusion: Our research illustrates that employees' workload has an impact on the intention of using digital applications. The higher the workload, the more people are willing to use TEPs. Regarding active knowledge sharing, we see that employees with low work satisfaction are more likely to share their digital knowledge compared to employees with high work satisfaction. This might be attributed to the Dunning-Kruger effect. Highly knowledgeable employees initially feel uncertain about the change, which translates into temporarily lower work satisfaction. They feel the urge to fill even small knowledge gaps, which in return leads to higher work satisfaction. Those responsible need to acknowledge that digital change affects their employees' workflow and work satisfaction. During such times, employees need time and support to gather information and knowledge in order to cope with digitally changed tasks., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Hasebrook et al.

- Abstract
Background: The safe indication and performance of thoracic emergency procedures are crucial and potentially lifesaving in prehospital emergency care. This study aims to investigate issues of patient safety and quality assurance of prehospital invasive thoracic interventions. The survey does not represent the actual medical care situation but explores reasons for security concerns among emergency physicians., Methods: Using a pre-validated questionnaire, prehospital emergency physicians of three prehospital rescue associations (Zweckverband) in Southwest Saxony, Greifswald, and Vechta, Germany, were queried via the online survey service limesurvey. The survey was conducted between January and March 2022., Results: 104 emergency physicians participated (response rate 42.4%) 71 of which fully completed the survey (68%). 79% of the participants stated that they felt safe in performing pleural punction. Common reasons for postponing prehospital thoracic interventions included fear of complications or individual patient characteristics. 90% said that they were familiar with the on-board equipment options, and 60% reported that resources were sufficient to perform double-sided procedures. While in all three regions there is sufficient on-board equipment to perform procedures on two sides, one out of two participants said that lack of equipment deters them from performing prehospital invasive thoracic procedures. Emergency physicians who graduated from trauma courses and/or participate in air rescue are more likely to perform invasive thoracic procedures. More than half of the participants wanted more training in chest tube placement or pleural punction., Conclusion: Safety in prehospital invasive thoracic procedures needs improvement in structural, procedural, as well as human factors aspects. Safe handling of these rare but vital techniques requires more training. A lack of knowledge of equipment is a significant safety gap. Prehospital ultrasound constitutes a structural element of prehospital diagnostics., (Copyright © 2022. Published by Elsevier GmbH.)

- Abstract
Background and Objectives: In 2017, a tele-emergency-physician system was implemented in the county of Vorpommern-Greifswald (Germany) to optimise the prehospital emergency medical service and to counteract current challenges. It was evaluated from a medical and economic perspective whether a tele-emergency physician system is a useful addition to the existing prehospital emergency system, especially in rural regions., Materials and Methods: Approximately 250,000 emergency medical service data from the years 2015 to 2020 (before and after the implementation of the telemedical system) were analysed in a pre-post comparison. A total of 3611 tele-emergency physician cases were analysed regarding medical indication and time-related factors. Additionally, total costs of the tele-emergency physician system as well as a cost analysis regarding prehospital and hospital medical costs of selected diseases were performed., Results: The tele-emergency physician treated patients of all age groups with a wide spectrum of diseases. Of the cases, 48.2% were moderate to severe but not life-threatening disorders. Patients as well as emergency medical service personnel embraced the new system. According to the data, ambulances that were equipped with the telemedical system had the number of missions requiring an emergency physician on scene reduced significantly by 20%. The yearly costs of this telemedical system amount to €1.7 million., Conclusions: The tele-emergency physician system proved to be a telemedical innovation that is medically advisable, functional and cost-efficient. Therefore, the tele-emergency physician system continued to operate after the end of the research project and is ready to be implemented across Germany., (© 2022. The Author(s).)

- Abstract
Background: Coronavirus disease 2019 (COVID-19) has brought about unprecedented challenges to medical schools. Physical distancing as the most effective means of infection prevention renders traditional classroom teaching nearly impossible and new teaching methods are required to contain the infection risk whilst ensuring high-level education., Objective: In order to minimize the need for classroom teaching we have created an interactive multimedia eLearning environment using the open-source learning management system "Moodle". This article describes the development of the eLearning environment and aims to establish the acceptance of technology-enhanced learning (TEL) among medical students and the evaluation of TEL as an alternative to classroom teaching., Material and Methods: We have built a multimedia eLearning environment for fourth year medical students covering the medical school curriculum "anesthesiology and emergency medicine", which is based on the recommendations of the German Society for Anesthesiology and Intensive Care Medicine (DGAI). We have chosen the open-source learning management system "Moodle" as a platform. "Moodle" is widely used by Anglo-American educational institutions to support and conduct academic and nonacademic teaching. In order to assess the students' experience, we have carried out an anonymized post-course survey consisting of multiple-choice and free-answer questions., Results: Of the 157 participants 85.4% rated the course as "very good", 12.1% as "good" and 1.9% as "OK". Lower ratings were not given, 54.8% rated the course content as "very relevant", 43.3% as "relevant" and 1.9% as "neutral", 94.3% felt that more comparable online courses should be offered. The free-text answers revealed that accessibility and multimedia self-controlled learning were highly valued; however, it was felt that hands-on training cannot be replaced by eLearning., Conclusion: Technology Enhanced Learning was highly valued by our students and helped to reduce the need for classroom teaching; however, for teaching practical skills classroom teaching remains indispensable., (© 2021.

Background: In medical events, patients have to independently decide whom to contact: emergency medical services, medical on-call service or emergency department., Objectives: Are Germans able to assess the urgency of medical events and choose the correct resource?, Materials and Methods: In 2018 a nationwide anonymous telephone survey was done in Gabler-Haeder design. In all, 708 interviewees were presented with six medical scenarios. Participants were asked to rate urgency and to assess whether medical help was necessary within minutes to hours. Telephone numbers of emergency medical services and medical on-call service were inquired., Results: Urgency of different scenarios was often misjudged: in cases with high, medium, and low urgency the misjudgement rate were 20, 50, and 27%, respectively. If medical help was rated as necessary, some participants chose the wrong service: 25% would not call an ambulance in stroke or myocardial infarction. In cases with medium urgency, more respondents chose to consult an emergency department (38%) than to call medical on-call service (46%)., Conclusions: Knowledge regarding different options for treatment of medical events and competence to assess urgency seem to be too low. Beside efforts to increase health literacy, one solution might be to introduce a joint telephone number for emergency medical services and medical on-call service with a uniform assessment tool and appropriate allocation., (© 2021.

- Abstract
Background: Dispatching first responders (FR) to out-of-hospital cardiac arrest in addition to the emergency medical service has shown to increase survival. The promising development of FR systems over the past years has been challenged by the outbreak of COVID-19. Whilst increased numbers and worse outcomes of cardiac arrests during the pandemic suggest a need for expansion of FR schemes, appropriate risk management is required to protect first responders and patients from contracting COVID-19. This study investigated how European FR schemes were affected by the pandemic and what measures were taken to protect patients and responders from COVID-19., Methods: To identify FR schemes in Europe we conducted a literature search and a web search. The schemes were contacted and invited to answer an online questionnaire during the second wave of the pandemic (December 2020/ January 2021) in Europe., Results: We have identified 135 FR schemes in 28 countries and included responses from 47 FR schemes in 16 countries. 25 schemes reported deactivation due to COVID-19 at some point, whilst 22 schemes continued to operate throughout the pandemic. 39 schemes communicated a pandemic-specific algorithm to their first responders. Before the COVID-19 outbreak 20 FR systems did not provide any personal protective equipment (PPE). After the outbreak 19 schemes still did not provide any PPE. The majority of schemes experienced falling numbers of accepted call outs and decreasing registrations of new volunteers. Six schemes reported of FR having contracted COVID-19 on a mission., Conclusions: European FR schemes were considerably affected by the pandemic and exhibited a range of responses to protect patients and responders. Overall, FR schemes saw a decrease in activity, which was in stark contrast to the high demand caused by the increased incidence and mortality of OHCA during the pandemic. Given the important role FR play in the chain of survival, a balanced approach upholding the safety of patients and responders should be sought to keep FR schemes operational., (© 2022.

- Abstract
Background: One of the health policy challenges lies in guaranteeing comprehensive emergency care in Germany. Telemedical applications are assumed to be a potential solution to current problems. One of these innovations is the tele-emergency physician system, which changes the workflows of the various actors in prehospital emergency medicine. The aim of the study was to determine how the potentials of the tele-emergency physician system were evaluated by employees of the ambulance control centres in Germany., Method: In the cross-sectional study, employees of ambulance control centres throughout Germany were interviewed using an online-based questionnaire. The results are illustrated in a sub-group analysis according to the state of knowledge on innovation, either (very) low or (very) high. Correlation analyses were carried out to determine significant differences between the subgroups. Data analysis was performed using Microsoft Excel 2013 and IBM SPSS Version 25., Results: The response rate was 69.04%. Of those surveyed, 76.23% expected that the tele-emergency physician system would save them a relevant amount of time. 57.38% believed that patients would be transported faster and 51.64% of the respondents did not see any chance of cost savings in the health care system. Significant evaluation differences resulted in expected time saving (p=0.004), shorter time to transport (p=0.009) and cost saving (p=0.0004). 64.71% thought that there would be a risk of increased documentation effort. 56.41% did not believe that patients would be sufficiently informed about the legal provisions on data protection during their tele-emergency physician treatment. The increase in documentation effort (p=0.02) and patients being sufficiently informed about data protection regulations (p=0.015) were evaluated significantly differently. 90.98% of the respondents rated the tele-emergency physician system as meaningful. The rural region was considered by 47.62% of the respondents as the primary region where the use of system would be necessary. 36.29% of the participants stated that a tele-emergency physician system should be implemented in their own area., Conclusion: All in all, the tele-emergency physician system is considered useful in prehospital emergency medical service by the staff of the emergency control centres. However, the majority of participants do not assume that there is potential for implementation of this system in their own region., Competing Interests: Die Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht., (Thieme.

- Abstract
Background: Witnessing an out-of-hospital cardiac arrest (OHCA) is a traumatic experience. This study analyses bystanders` psychological processing of OHCA. We examined the potential impact of bystanders performing resuscitation and the influence of the relationship between bystander and patient (stranger vs. family/friend of the patient) on the psychological processing., Methods: A telephone interview survey with bystanders, who witnessed an OHCA of an adult patient was performed weeks after the event between December 2014 and April 2016. The semi-standardized questionnaire contained a question regarding the paramount emotion at the time of the interview. In a post-hoc analysis statements given in response were rated by independent researchers into the categories "signs of pathological psychological processing", "physiological psychological processing" and "no signs of psychological distress due to the OHCA"., Results: In this analysis 89 telephone interviews were included. In 27 cases (30.3%) signs of pathological psychological processing could be detected. Bystanders performing resuscitation had a higher rate of "no signs of psychological distress after witnessing OHCA" compared to those not resuscitating (54.7% vs. 26.7%, p < 0.05; relative risk 2.01; 95%CI 1.08, 3.89). No statistical significant differences in the psychological processing could be shown for gender, age, relationship to the patient, current employment in the health sector, location of cardiac arrest or number of additional bystanders., Conclusions: One out of three bystanders of OHCA suffers signs of pathological psychological processing. This was independent of bystander´s age, gender and relationship to the patient. Performing resuscitation seems to help coping with witnessing OHCA., (© 2021. The Author(s).)

- Abstract
Background: Bystander-initiated resuscitation is essential for surviving out-of-hospital cardiac arrest. Smartphone apps can provide real-time guidance for medical laypersons in these situations. Are these apps a beneficial addition to traditional resuscitation training?, Methods: In this controlled trial, we assessed the impact of app use on the quality of resuscitation (hands-off time, assessment of the patient's condition, quality of chest compression, body and arm positioning). Pupils who have previously undergone a standardised resuscitation training, encountered a simulated cardiac arrest either (i) without an app (control group); (ii) with facultative app usage; or (iii) with mandatory app usage. Measurements were compared using generalised linear regression., Results: 200 pupils attended this study with 74 pupils in control group, 65 in facultative group and 61 in mandatory group. Participants who had to use the app significantly delayed the check for breathing, call for help, and first compression, leading to longer total hands-off time. Hands-off time during chest compression did not differ significantly. The percentage of correct compression rate and correct compression depth was significantly higher when app use was mandatory. Assessment of the patient's condition, and body and arm positioning did not differ., Conclusions: Smartphone apps offering real-time guidance in resuscitation can improve the quality of chest compression but may also delay the start of resuscitation. Provided that the app gives easy-to-implement, guideline-compliant instructions and that the user is familiar with its operation, we recommend smartphone-guidance as an additional tool to hands-on CPR-training to increase the prevalence and quality of bystander-initiated CPR.

- Abstract
Background and Objective: Teleemergency doctors support ambulance cars at the emergency site by means of telemedicine. Currently, each district has its own teleemergency doctor office (decentralized solution). This paper analyses the advantages and disadvantages of a centralized solution where several teleemergency doctors work in parallel in one office to support the ambulances in more districts., Methods: The service of incoming calls from ambulances to the teleemergency doctor office can be modelled as a queuing system. Based on the data of the district of Vorpommern-Greifswald in the Northeast of Germany, we assume that arrivals and services are Markov chains. The model has parallel channels proportionate to the number of teleemergency doctors working simultaneously and the number of calls which one doctor can handle in parallel. We develop a cost function with variable, fixed and step-fixed costs., Results: For the district of Greifswald, the likelihood that an incoming call has to be put on hold because the teleemergency doctor is already fully occupied is negligible. Centralization of several districts with a higher number of ambulances in one teleemergency doctor office will increase the likelihood of overburdening and require more doctors working simultaneously. The cost of the teleemergency doctor office per ambulance serviced strongly declines with the number of districts cooperating., Discussion: The calculations indicate that centralization is feasible and cost-effective. Other advantages (e.g. improved quality, higher flexibility) and disadvantages (lack of knowledge of the location and infrastructure) of centralization are discussed., Conclusions: We recommend centralization of telemedical emergency services. However, the number of districts cooperating in one teleemergency doctor office should not be too high and the distance between the ambulance station and the telemedical station should not be too large.

- Abstract
Background: Over the past decade Smartphone-based activation (SBA) of Community First Responders (CFR) to out-of-hospital cardiac arrests (OHCA) has gained much attention and popularity throughout Europe. Various programmes have been established, and interestingly there are considerable differences in technology, responder spectrum and the degree of integration into the prehospital emergency services. It is unclear whether these dissimilarities affect outcome. This paper reviews the current state in five European countries, reveals similarities and controversies, and presents consensus statements generated in an international conference with the intention to support public decision making on future strategies for SBA of CFR., Methods: In a consensus conference a three-step approach was used: (i) presentation of current research from five European countries; (ii) workshops discussing evidence amongst the audience to generate consensus statements; (iii) anonymous real-time voting applying the modified RAND-UCLA Appropriateness method to adopt or reject the statements. The consensus panel aimed to represent all stakeholders involved in this topic., Results: While 21 of 25 generated statements gained approval, consensus was only found for 5 of them. One statement was rejected but without consensus. Members of the consensus conference confirmed that CFR save lives. They further acknowledged the crucial role of emergency medical control centres and called for nationwide strategies., Conclusions: Members of the consensus conference acknowledged that smartphone-based activation of CFR to OHCA saves lives. The statements generated by the consensus conference may assist the public, healthcare services and governments to utilise these systems to their full potential, and direct the research community towards fields that still need to be addressed.

- Abstract
Background: The prevalence of Vibrio vulnificus heavily depends on the temperature and salinity of the sea water. In the course of climate change an increase in cases of fatal sepsis caused by V. vulnificus at the German Baltic Sea coast could be detected., Objective: To generate awareness for a life-threatening infection with increasing incidence in Germany., Material and Methods: This article presents an overview of the current state of the literature followed by an exemplary description of cases with V vulnificus sepsis caused by contact with water in the Baltic Sea, which were treated at the Medical University in Greifswald in summer 2018., Results: In the presence of risk factors, such as liver and kidney diseases, immunosuppression and male sex, there is a danger of severe sepsis if damaged skin comes into contact with contaminated sea water. A pronounced organ dysfunction can frequently be found on admission. In these cases the diagnosis must be made promptly and timely surgical cleansing and antibiotic treatment should be initiated (e.g. a combination of tetracyclines and third generation cephalosporins)., Conclusion: Sepsis due to V. vulnificus will probably increase over the coming years. Because there is a latency in some cases between infection and onset of sepsis, physicians beyond the coastal region must also be informed about this disease.

- Abstract
Background: German emergency medical services are a 2-tiered system with paramedic-staffed ambulances as the primary response, supported by prehospital emergency doctors for life-threatening conditions. As in all European health care systems, German medical practitioners are in short supply, whereas the demand for timely emergency medical care is constantly growing. In rural areas, this has led to critical delays in the provision of emergency medical care. In particular, in cases of cardiac arrest, time is of the essence because, with each passing minute, the chance of survival with good neurological outcome decreases., Objective: The project has 4 main objectives: (1) reduce the therapy-free interval through widespread reinforcement of resuscitation skills and motivating the public to provide help (ie, bystander cardiopulmonary resuscitation), (2) provide faster professional first aid in addition to rescue services through alerting trained first aiders by mobile phone, (3) make more emergency physicians available more quickly through introducing the tele-emergency physician system, and (4) enhance emergency care through improving the cooperation between statutory health insurance on-call medical services (German: Kassenärztlicher Bereitschaftsdienst) and emergency medical services., Methods: We will evaluate project implementation in a tripartite prospective and intervention study. First, in medical evaluation, we will assess the influences of various project measures on quality of care using multiple methods. Second, the economic evaluation will mainly focus on the valuation of inputs and outcomes of the different measures while considering various relevant indicators. Third, as part of the work and organizational analysis, we will assess important work- and occupational-related parameters, as well as network and regional indexes., Results: We started the project in 2017 and will complete enrollment in 2020. We finished the preanalysis phase in September 2018., Conclusions: Overall, implementation of the project will entail realigning emergency medicine in rural areas and enhancing the quality of medical emergency care in the long term. We expect the project to lead to a measurable increase in medical laypersons' individual motivation to provide resuscitation, to strengthen resuscitation skills, and to result in medical laypersons providing first aid much more frequently. Furthermore, we intend the project to decrease the therapy-free interval in cases of cardiac arrest by dispatching first aiders via mobile phones. Previous projects in urban regions have shown that the tele-emergency physician system can provide a higher availability and quality of emergency call-outs in regular health care. We expect a closer interrelation of emergency practices of statutory health insurance physicians with the rescue service to lead to better coordination of rescue and on-call services., International Registered Report Identifier (irrid): DERR1-10.2196/14358., (©Camilla Metelmann, Bibiana Metelmann, Dorothea Kohnen, Clara Prasser, Rebekka Süss, Julia Kuntosch, Dirk Scheer, Timm Laslo, Lutz Fischer, Joachim Hasebrook, Steffen Flessa, Klaus Hahnenkamp, Peter Brinkrolf.

- Abstract
Background: In case of a cardiac arrest, start of cardiopulmonary resuscitation by a bystander before the arrival of the emergency personnel increases the probability of survival. However, the steps of high-quality resuscitation are not known by every bystander or might be forgotten in this complex and time-critical situation. Mobile phone apps offering real-time step-by-step instructions might be a valuable source of information., Objective: The aim of this study was to examine mobile phone apps offering real-time instructions in German or English in case of a cardiac arrest, to evaluate their adherence to current resuscitation guidelines, and to test their usability., Methods: Our 3-step approach combines a systematic review of currently available apps guiding a medical layperson through a resuscitation situation, an adherence testing to medical guidelines, and a usability evaluation of the determined apps. The systematic review followed an adapted preferred reporting items for systematic reviews and meta-analyses flow diagram, the guideline adherence was tested by applying a conformity checklist, and the usability was evaluated by a group of mobile phone frequent users and emergency physicians with the system usability scale (SUS) tool., Results: The structured search in Google Play Store and Apple App Store resulted in 3890 hits. After removing redundant ones, 2640 hits were checked for fulfilling the inclusion criteria. As a result, 34 apps meeting all inclusion criteria were identified. These included apps were analyzed to determine medical accuracy as defined by the European Resuscitation Council's guidelines. Only 5 out of 34 apps (15%, 5/34) fulfilled all criteria chosen to determine guideline adherence. All other apps provided no or wrong information on at least one relevant topic. The usability of 3 apps was evaluated by 10 mobile phone frequent users and 9 emergency physicians. Of these 3 apps, solely the app "HELP Notfall" (median=87.5) was ranked with an SUS score above the published average of 68. This app was rated significantly superior to "HAMBURG SCHOCKT" (median=55; asymptotic Wilcoxon test: z=-3.63, P<.01, n=19) and "Mein DRK" (median=32.5; asymptotic Wilcoxon test: z=-3.83, P<.01, n=19)., Conclusions: Implementing a systematic quality control for health-related apps should be enforced to ensure that all products provide medically accurate content and sufficient usability in complex situations. This is of exceptional importance for apps dealing with the treatment of life-threatening events such as cardiac arrest., (©Bibiana Metelmann, Camilla Metelmann, Louisa Schuffert, Klaus Hahnenkamp, Peter Brinkrolf.

- Abstract
Background: All European countries need to increase the number of health professionals in the near future. Most efforts have not brought the expected results so far. The current notion is that this is mainly related to the fact that female physicians will clearly outnumber their male colleagues within a few years in nearly all European countries. Still, women are underrepresented in leadership and research positions throughout Europe., Objectives: The MedGoFem project addresses multiple perspectives with the participation of multiple stakeholders. The goal is to facilitate the implementation of Gender Equality Plans (GEP) in university hospitals; thereby, transforming the working conditions for women working as researchers and highly qualified physicians simultaneously. Our proposed innovation, a crosscutting topic in all research and clinical activities, must become an essential part of university hospital strategic concepts., Methods: We capture the current status with gender-sensitive demographic data concerning medical staff and conduct Web-based surveys to identify cultural, country-specific, and interdisciplinary factors conducive to women's academic success. Individual expectations of employees regarding job satisfaction and working conditions will be visualized based on "personal construct theory" through repertory grids. An expert board working out scenarios and a gender topic agenda will identify culture-, nation-, and discipline-specific aspects of gender equality. University hospitals in 7 countries will establish consensus groups, which work on related topics. Hospital management supports the consensus groups, valuates group results, and shares discussion results and suggested measures across groups. Central findings of the consensus groups will be prepared as exemplary case studies for academic teaching on research and work organization, leadership, and management., Results: A discussion group on gender equality in academic medicine will be established on an internationally renowned open-research platform. Project results will be published in peer-reviewed journals with high-impact factors. In addition, workshops on gender dimension in research using the principles of Gendered Innovation will be held. Support and consulting services for hospitals will be introduced in order to develop a European consulting service., Conclusions: The main impact of the project will be the implementation of innovative GEP tailored to the needs of university hospitals, which will lead to measurable institutional change in gender equality. This will impact the research at university hospitals in general, and will improve career prospects of female researchers in particular. Simultaneously, the gender dimension in medical research as an innovation factor and mandatory topic will be strengthened and integrated in each individual university hospital research activity. Research funding organizations can use the built knowledge to include mandatory topics for funding applications to enforce the use and implementation of GEP in university hospitals., (©Joachim Hasebrook, Klaus Hahnenkamp, Wolfgang F.F.A.

- Abstract
The aim of the study was to learn, whether clinical application of cold atmospheric pressure plasma (CAP) is able to cause (i) visible tumor surface effects and (ii) apoptotic cell kill in squamous cell carcinoma and (iii) whether CAP-induced visible tumor surface response occurs as often as CAP-induced apoptotic cell kill. Twelve patients with advanced head and neck cancer and infected ulcerations received locally CAP followed by palliative treatment. Four of them revealed tumor surface response appearing 2 weeks after intervention. The tumor surface response expressed as a flat area with vascular stimulation (type 1) or a contraction of tumor ulceration rims forming recesses covered with scabs, in each case surrounded by tumor tissue in visible progress (type 2). In parallel, 9 patients with the same kind of cancer received CAP before radical tumor resection. Tissue specimens were analyzed for apoptotic cells. Apoptotic cells were detectable and occurred more frequently in tissue areas previously treated with CAP than in untreated areas. Bringing together both findings and placing side by side the frequency of clinical tumor surface response and the frequency of analytically proven apoptotic cell kill, detection of apoptotic cells is as common as clinical tumor surface response. There was no patient showing signs of an enhanced or stimulated tumor growth under influence of CAP. CAP was made applicable by a plasma jet, kINPen(®) MED (neoplas tools GmbH, Greifswald, Germany)., (Copyright © 2016. Published by Elsevier Ltd.)

- Abstract
Triterpenes are demonstrably effective for accelerating re-epithelialisation of wounds and known to improve scar formation for superficial lesions. Among the variety of triterpenes, betuline is of particular medical interest. Topical betuline gel (TBG) received drug approval in 2016 from the European Commission as the first topical therapeutic agent with the proven clinical benefit of accelerating wound healing. Two self-conducted randomized intra-individual comparison clinical studies with a total of 220 patients involved in TBG treatment of skin graft surgical wounds have been screened for data concerning the aesthetic aspect of wound healing. Three months after surgery wound treatment with TBG resulted in about 30% of cases with more discreet scars, and standard of care in about 10%. Patients themselves appreciate the results of TBG after 3 months even more (about 50%) compared to standard of care (about 10%). One year after surgery, the superiority of TBG counts for about 25% in comparison with about 10%, and from the patients' point of view, for 25% compared to 4% under standard of care. In the majority of wound treatment cases, there is no difference visible between TBG treatment and standard of care after 1 year of scar formation. However, in comparison, TBG still offers a better chance for discreet scars and therefore happens to be superior in good care of wounds.
