RESUMO
BACKGROUND: Training schoolchildren in resuscitation seems to improve rates of resuscitation by bystanders. Leading medical societies recommend comprehensive resuscitation education in schools. To date, no widespread implementation within the European Union has happened. OBJECTIVE: The study aim was to identify facilitators and barriers for the implementation of cardiopulmonary resuscitation training for schoolchildren within the European Union. DESIGN: Systematic review. DATA SOURCES: A literature search in PubMed was conducted between 1 January 1999 and 30 June 2020 in accordance with the PRISMA statement. The search terms 'resuscitation', 'children' and 'Europe' were combined with the Boolean Operator 'AND' and 'OR'. Medical subject heading terms were used in order to include relevant articles. ELIGIBILITY CRITERIA: Articles were included if cardiopulmonary resuscitation training specifically tailored for schoolchildren aged 12 to 18âyears was considered in countries of the European Union. Articles that fulfilled the following criteria were excluded: duplicates, training methods only for specific patient groups, articles not accessible in the English language, and articles that did not include original data.Findings were structured by an evidence-based six-level approach to examine barriers and facilitators in healthcare. RESULTS: Thirty out of 2005 articles were identified. Large variations in cardiopulmonary resuscitation training approaches ranging from conventional to innovative training methods can be observed. Schoolteachers as resuscitation instructors act either as barrier or facilitator depending on their personal attitude and their exposure to training in resuscitation. Cardiopulmonary resuscitation training in schoolchildren is effective. The uncoordinated interplay between the generally motivated schools and the political orientation towards resuscitation training for schoolchildren serve as barrier. The lack of financial support, absent systematic organisation, and standardisation of training create major barriers. CONCLUSION: Training schoolchildren in cardiopulmonary resuscitation is effective. More financial support and political guidance is needed. Until then, local initiatives, motivated teachers, and dedicated principles combined with innovative and low-cost training methods facilitate cardiopulmonary resuscitation training in schools.

BACKGROUND: Telephone-assisted cardiopulmonary resuscitation (CPR) is an effective and proven tool to improve patient survival and outcome after cardiac arrest, and is therefore recommended in international resuscitation guidelines. A new technology that provides the emergency medical services (EMS) dispatcher with a video livestream from a smartphone during telephone-assisted CPR was investigated to assess whether a correct judgment of CPR quality is feasible. MATERIAL AND METHODS: After Ethics Committee approval, we conducted this study from August to September 2018 in the University Hospital of Cologne and its metropolitan area. Our study team set up a full-scale resuscitation mannequin on 54 study sites. Video telephony between caller and EMS dispatcher was established, and CPR was initiated with randomized common quality issues concerning compression frequency, compression depth, and compression point. It was evaluated whether the dispatcher recognized correct and incorrect resuscitation performance. RESULTS: Forty-six video calls were established successfully. EMS dispatching staff identified correct compression frequency (100-120/min) in 87.5% of the cases, too low frequency (<80/min) was correctly identified in 92%, and too high frequency (>140/min) in 58.5%, respectively. Correct compression depth (5-6 cm) was identified in 70.6%, shallow compressions (<3cm) in 92.9% and a continuous decrease of depth in 100% of all cases. Correct compression point was identified in 87.5%, incorrect epigastric compression in 92.3%, incomplete release in 58.8%. CONCLUSION: A video livestream from a smartphone can support an EMS dispatcher's assistance in resuscitation. Typical resuscitation mistakes, like incorrect compression frequency or depth, and incorrect compression points could be recognized and corrected efficiently via video livestream.

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.

BACKGROUND: Despite intensive research, cardiac arrest remains a leading cause of death. It is of paramount importance to undertake every possible effort to increase the overall quality of cardiopulmonary resuscitation (CPR) and improve patient outcome. CPR initiated by a bystander is one of the key factors in survival of such an incident. Telephone-assisted CPR (T-CPR) has proved to be an effective measure in improving layperson resuscitation. OBJECTIVE: We hypothesised that adding video-telephony to the emergency call (video-CPR, V-CPR) enhances the quality of layperson resuscitation. DESIGN: This randomised controlled simulation trial was performed from July to August 2018. Laypersons were randomly assigned to video-assisted (V-CPR), telephone-assisted (T-CPR) or control (unassisted CPR) groups. Participants were instructed to perform first aid on a mannequin during a simulated cardiac arrest. SETTING: This study was conducted in the Skills Lab of the University Hospital of Cologne. PARTICIPANTS: One hundred and fifty healthy adult volunteers. INTERVENTION: The participants received a smartphone to call emergency services, with Emergency Eye video-call in V-CPR group, and normal telephone functionality in the other groups. T-CPR and V-CPR groups received standardised CPR assistance via phone. MAIN OUTCOME MEASURES: Our primary endpoint was resuscitation quality, quantified by compression frequency and depth, and correct hand position. RESULTS: Mean compression frequency of V-CPR group was 106.4â±â11.7âmin, T-CPR group 98.9â±â12.3âmin (NS), unassisted group 71.6â±â32.3âmin (Pâ<â0.001). Mean compression depth was 55.4â±â12.3âmm in V-CPR, 52.1â±â13.3âmm in T-CPR (Pâ<â0.001) and 52.9â±â15.5âmm in unassisted (Pâ<â0.001). Total percentage of correct chest compressions was significantly higher (Pâ<â0.001) in V-CPR (82.6%), than T-CPR (75.4%) and unassisted (77.3%) groups. CONCLUSION: V-CPR was shown to be superior to unassisted CPR, and was comparable to T-CPR. However, V-CPR leads to a significantly better hand position compared with the other study groups. V-CPR assistance resulted in volunteers performing chest compressions with more accurate compression depth. Despite reaching statistical significance, this may be of little clinical relevance. TRIAL REGISTRATION: ClinicalTrials.gov (Identifier: NCT03527771).

BACKGROUND: Education of schoolchildren in cardiopulmonary resuscitation (CPR) is a strategic goal for improvement of bystander CPR in society. OBJECTIVE(S): The primary objective was to analyse the impact of CPR training on the resuscitation knowledge and self-confidence of secondary schoolchildren. In addition, independent predictors of improved CPR knowledge and self-confidence were investigated. DESIGN: Randomised-interventional controlled study. SETTING: Four secondary schools in Germany. PARTICIPANTS: Four hundred and twenty-four schoolchildren aged from 14 to 18 years were included into the study. Fifty-one percent were female, and 33% had an immigrant background. INTERVENTION: The intervention group received a 90-min CPR training session, whereas controls had no intervention. Levels of knowledge and self-confidence in initiating CPR were analysed by a study questionnaire before (t0), 90âmin after (t1) and 6 months after training (t2). MAIN OUTCOME MEASURES: Based on the evaluation of study questionnaires, the primary endpoint was to determine the development of resuscitation knowledge and self-confidence in initiating cardiopulmonary resuscitation at survey time-points t0, t1 and t2. RESULTS: Schoolchildren in the intervention group (n=207) showed a significantly higher level of knowledge (Pâ<â0.001) and self-confidence (Pâ<â0.001) at t1 and t2 compared with controls (n=217). Age was a predictor for long-term self-confidence [odds ratio (OR), 1.20; 95% confidence interval (95% CI), 1.02 to 1.41; Pâ=â0.032]. The long-term benefit in the level of knowledge and self-confidence were significantly higher in native compared with immigrant schoolchildren: (OR, 1.79; 95% CI, 1.14 to 2.82; Pâ=â0.011) and (OR, 1.67; 95% CI, 1.07 to 2.60; Pâ=â0.024), respectively. CONCLUSION: Guideline compliant (90âmin) theoretical and practical CPR training improves the level of knowledge and self-confidence in 14 to 18-year-old schoolchildren. Older schoolchildren are more likely to have increased self-confidence with respect to initiating CPR. Schoolchildren with an immigrant background showed a significantly lower increase in their level of knowledge and self-confidence compared with native children. Adaptation and simplification of teaching materials and further research on educational methods for CPR are urgently needed to enable a sustainable approach to teaching CPR, which also produces a long-lasting effect in the entire population.

This qualitative study aims to analyse the personal qualification, attitudes and the pedagogical concepts of German teachers as experts in their profession regarding basic life support (BLS) education in secondary schools. Thirteen (n = 13) secondary school teachers participated in semi-structured expert interviews and were interviewed for at least 20 to 60 min regarding BLS student education. Interviews were semi-structured with guiding questions addressing (1) personal experience, (2) teacher qualification for BLS and (3) implementation factors (e.g., personal, material and organisational). Audio-recorded interviews were analysed by content analysis, generating a coding system. School teachers provided a heterogeneous view on implementation-related processes in BLS education. Many teachers were educated in first aid, acknowledge its importance, but had no experience in teaching BLS. They want to assure being competent for teaching BLS and need tailored trainings, materials, pedagogical information and the incorporation into the curriculum. Also, the management of time constraints, unwilling colleagues, or young students being overwhelmed were commonly mentioned considerations. Concluding, teachers reported to be willing to teach BLS but a stepwise implementation framework incorporating practice-oriented qualification and educational goals is missing.
RESUMO
Background: App-linked real-time feedback-devices for cardiopulmonary resuscitation (CPR) aim to improve laypersons' resuscitation quality. Resuscitation guidelines recommend these technologies in training settings. This is the first study comparing resuscitation quality of all App-linked feedback-devices currently on market. Methods: A prospective randomised simulation study was performed. After standardised instructions, participants performed 2-minutes compression-only CPR on a manikin without feedback (baseline). Afterwards, participants performed 4 × 2 min CPR with four different feedback devices in randomised order (CorPatch® Trainer, CPRBAND AIO Training, SimCPR®ProTrainer, Relay Response™) (intervention). CPR metrics (chest compression depth (CD), chest compression rate (CR), percentage of correct CD/CR (%), correct hand position, correct chest recoil, and technical preparation-time) were assessed. Devices data were compared to the baseline group using Wilcoxon testing with IBM SPSS (primary outcome). Differences between devices were analysed with ANOVA testing (secondary outcome). Normally distributed data were described as mean ± standard deviation (SD) and non-normally distributed data as Median [Interquartile range (IQR). CPR self-confidence was measured by means of questionnaire before and after feedback devices' use. Comparison was performed by students t-test. Results: Forty participants were involved. SimCPR®ProTrainer was the only device, which resulted in guideline-compliant chest compressions (Mean ± SD:5.37 ± 0.76) with improved chest compression depth (p < 0.001), and percentage of correct chest compression depth (p < 0.001) compared to unassisted CPR (baseline). CorPatch® Trainer as the only device with audio-visual recoil instructions resulted in improved chest recoil (Mean ± SD:72.25 ± 24.89) compared to baseline (Mean ± SD:49.00 ± 42.20; p < 0.01), while the other three devices resulted in significantly lower chest recoil rates (CPRBAND AIO Training: 37.03 ± 39.90; p < 0.01, SimCPR®ProTrainer: Mean ± SD:39.88 ± 36.50; p = 0.03, Relay Response™: Mean ± SD:36.88 ± 37.73; p = 0.02). CPR quality when using the different feedback devices differ in chest compression depth (p = 0.02), chest compression rate (p < 0.001), percentage of correct chest compression depth/rate (p = 0.03/p = 0.04), and technical preparation-time (p < 0.001). Feedback-devices' use increased participant's CPR self-confidence (p < 0.001). Conclusion: Although, CPR feedback devices show improved CPR performance in layperson in some metrics, none of the tested CPR feedback devices supported layperson in overall adequate CPR performance. More and better technical functionality is necessary, to fully utilise the potential of CPR feedback devices and to prevent a worsening of CPR performance when layperson use this technology.
RESUMO
BACKGROUND: Since 2015, the international resuscitation guidelines recommend the implementation of specialized hospitals (so-called cardiac arrest centers, CAC) for patients with out-of-hospital cardiac arrest (OHCA). OBJECTIVES: The aim was to investigate the potential influence of hospital certification as a CAC on the decision of emergency medical service staff (EMS, including out-of-hospital emergency physicians and paramedics) when transporting OHCA patients to a hospital. MATERIALS AND METHODS: A web-based, anonymous questionnaire with 20 items was performed from 15 May 2018 to 15 June 2018 in Germany. Target groups were out-of-hospital emergency physicians and paramedics. RESULTS: Of 437 respondents, 378 responses (nâ¯= 292 emergency physicians, nâ¯= 86 paramedics) were included in the statistical analysis. In all, 75.1% (nâ¯= 284) indicated that CAC certification of hospitals would matter in their own transportation decisions for OHCA patients in future transportations, 78.3% (nâ¯= 296) expected that CAC certification will result in an improvement in patient care, and 78.8% (nâ¯= 298) were in favor of implementing the CAC certification. Respondents would accept an additional 16.3â¯min (95% confidence interval 15.2-17.3) of transportation time to reach a CAC. CONCLUSIONS: Certification of hospitals as CAC has the potential to influence emergency medical personnel decisions about which hospital to transport OHCA patients to. Due to the limited additional acceptable transport time to reach a CAC, a close network of certified hospitals is needed nationwide.

INTRODUCTION: Video-assisted cardiopulmonary resuscitation (V-CPR) describes an advanced telephone-assisted CPR (T-CPR), in which emergency medical service (EMS) dispatchers view a live video steam of the resuscitation. Dispatchers ' general attitudes toward and self-assessment in V-CPR have not been previously investigated. MATERIAL AND METHODS: We conducted this quantitative analysis along with a pilot study on V-CPR. After conducting V-CPR with laypersons in a simulation, EMS dispatchers were given questionnaires with 21 items concerning their personal attitude toward V-CPR and their self-assessment in providing instructions. The actual CPR performance achieved was recorded and compared to the dispatchers' self-assessments. RESULTS: Dispatchers completed 49 questionnaires, and the data is presented descriptively. Over 80% strongly agreed that V-CPR was helpful in guiding and that their feedback improved CPR quality. Fifty-one percent agreed that video images supported them in making a diagnosis, while 44.9% disagreed. A vast majority (80-90% each) strongly agreed that V-CPR helped them recognize CPR issues such as compression point, compression rate, and deterioration. In contrast, data for improved compression depth and release were weaker. Thirty percent found V-CPR to be more stressful or exhausting than T-CPR. A majority stated they would prefer V-CPR as an addition to T-CPR in the future. There was a huge gap between dispatchers' own view of CPR effort and measured CPR quality. CONCLUSION: Dispatchers generally embrace V-CPR and praise the abilities it provides. Our results indicate that the use of V-CPR did not automatically result in an overall improvement in guideline-compliant CPR quality.

Background: A victim's gender is a known factor that influences the willingness of adult bystanders to perform cardiopulmonary resuscitation (CPR) if an out-of-hospital cardiac arrest (OHCA) occurs. This study aims to identify whether gender characteristics of OHCA victims are also relevant to schoolchildren, who are the key target group of CPR trainings worldwide. Methods: A prospective, educative intervention study was performed in schoolchildren (5th−7th grade). Schoolchildren's willingness to perform CPR was assessed by means of questionnaires before (t0) and after (t1) standardized CPR training. Participants were asked how determined they were to perform CPR in male and female OHCA victims on a 5-point Likert scale (not being determined to being very determined). A data analysis was performed according to the gender characteristics of schoolchildren. Results: Overall, 342 schoolchildren aged 10−15 years were included, and 166 male (MG) and 176 female (FG) schoolchildren served as a comparison group. Before (t0) and after (t1) the intervention, females showed a significantly higher general willingness to perform CPR than males (t0: 97.1% vs. 89.0%; p < 0.003 and t1: 95.7% vs. 98.9%; p = 0.038). The general willingness to perform CPR after training had a stronger increase in males (8.0% vs. 2.3%; p = 0.017). In the case that the OHCA victim was female, male schoolchildren were less willing to perform CPR than females at baseline (MG: n = 101;60.8% vs. FG: n = 147;84.5%; p < 0.001) and after training (MG: n = 97;58.4% vs. FG: n = 138;79.3%; p < 0.001). At t1, CPR willingness for female victims was improved in males (MG: n = 36;21.7% vs. FG: n = 19;10.9%; p = 0.006). Conclusions: The gender characteristics of OHCA victims, as well as schoolchildren themselves, have a relevant impact on the willingness to perform CPR. Training concepts should effectively motivate male schoolchildren to reduce preexisting inhibitions, especially towards female OHCA patients. Trial registration: This study was registered at the German Clinical Trials Register (Registration number: DRKS00017707) on 2 August 2019.
RESUMO
INTRODUCTION: Widespread use of smartphones allows automatic geolocalization (i.e., transmission of location data) in countless apps. Until now, this technology has not been routinely used in connection with an emergency call in which location data play a decisive role This study evaluated a new software automatically providing emergency medical service (EMS) dispatchers with a caller's geolocation. We hypothesized that this technology will provide higher accuracy, faster dispatching of EMS and a faster beginning of thoracic compressions in a cardiac arrest scenario. MATERIAL AND METHODS: Approval from the local Ethics Committee was obtained. 108 simulated emergency calls reporting a patient in cardiac arrest were conducted at 54 metropolitan locations, which were chosen according to a realistic pattern. At each location, a conventional emergency call, with an oral description of the location, was given first; subsequently, another call using an app with automatic geolocation was placed. Accuracy of localization, time to location, time to EMS dispatch and time to first thoracic compression were compared between both groups. RESULTS: The conventional emergency call was always successful (nâ¯=â¯54). Emergency call via app worked successfully in nâ¯=â¯46 cases (85.2%). Automatic geolocation was provided to EMS in all these nâ¯=â¯46 cases (100%). Deviation from estimated position to actual position was 1173.5⯱â¯4343.1â¯m for conventional and 65.6⯱â¯320.5â¯m for automatic geolocalization (pâ¯<â¯0.001). In addition, time to localization was significantly shorter using automatic geolocalization (34.7 vs. 71.7â¯s, pâ¯<â¯0.001). Time to first thoracic compression was significantly faster in the geolocalization group (83.0 vs. 122.6â¯s; pâ¯<â¯0.001). CONCLUSIONS: This pilot study showed that automatic geolocalization leads to a significantly shorter duration of the emergency call, significantly shorter times until the beginning of thoracic compressions, and a higher precision in determining the location of an emergency.

AIM: Bystander CPR-rates are embarrassingly low in some European countries. To increase bystander CPR-rates, many different approaches are used; one of them is training of schoolchildren in CPR. Multiple authors investigated practical and theoretical CPR performance and demonstrated gender differences related to schoolchildren CPR. The objective was to elaborate gender aspects in practical and theoretical CPR-performance from the current literature to better address female and male students. METHODS: A systematic search in PubMed-database with different search terms was performed for controlled and uncontrolled prospective investigations. Altogether, nâ¯=â¯2360 articles were identified and checked for aptitude. From nâ¯=â¯97 appropriated articles, nâ¯=â¯24 met the inclusion criteria and were finally included for full review and incorporated in the manuscript. RESULTS: Female students demonstrated higher motivation to attend CPR-training (pâ¯<â¯0.001), to respond to cardiac arrest (CA) (pâ¯<â¯0.01), scored higher in a CPR-questionnaire (pâ¯<â¯0.025), revealed better remembrance of the national emergency phone-number (pâ¯<â¯0.05) and showed a higher multiplier effect (pâ¯<â¯0.0001). Male students showed higher confidence in CPR-proficiency (pâ¯<â¯0.05), revealed deeper chest compressions (CC) (pâ¯<â¯0.001; pâ¯<â¯0.0015; pâ¯<â¯0.01), a higher CC-fraction (pâ¯<â¯0.01) and a higher arbitrary cardiac output simulated equivalent index (pâ¯<â¯0.05). Male gender could not be detected to be a predictor for higher tidal volume (pâ¯=â¯0.70; pâ¯=â¯0.0212). CONCLUSION: In context of schoolchildren CPR, gender aspects are underestimated. Female students seem to be more motivated to attend CPR-training, reach more people in the role of a multiplier and need to be individually addressed in intensified practical training. Male students achieve a more sufficient chest compression depth and -fraction and could benefit from individual motivation.
