Manikin physical realism for resuscitation education: A systematic review

Aim

To evaluate the impact of higher physical realism of manikins on educational and clinical outcomes during life support education.

Methods

This systematic review was conducted as part of the continuous evidence evaluation process of the International Liaison Committee on Resuscitation (ILCOR). A search of PubMed, Embase, and Cochrane was conducted from January 1, 2005 until April 30, 2024. Studies comparing training with higher physical realism manikins and lower realism manikins were eligible for inclusion. Studies comparing manikins to other forms of training (e.g. screen-based, virtual reality) were excluded. Risk of bias was assessed using Cochrane Risk of Bias 2 (RoB 2) for randomized trials and Risk Of Bias In Non-Randomized Studies of Interventions (ROBINS-I) for observational studies. For outcomes reported by four or more randomized studies, random effects meta-analysis using standardized mean difference was performed.

Results

Of the 1276 articles identified and screened, 21 articles comprised the final review (19 randomized trials, 2 observational studies). Meta-analysis of eight RCTs reporting simulation skill performance in a simulated clinical scenario at course conclusion demonstrated a benefit from the use of higher- realism manikins compared with lower realism manikins (standardized mean difference 0.66, 95% CI 0.08 - 1.25). Meta-analysis of seven RCTs reporting knowledge at course conclusion showed no significant difference between the use of both types of manikins. Significant risk of bias and a high degree of heterogeneity were found among the included studies.

Conclusion

This systematic review found that higher manikin realism during resuscitation training was associated with improved simulated clinical scenario performance at course conclusion; without an effect on knowledge at course conclusion. Future studies should examine the impact of resource requirements for high realism simulation on generalizability and implementation.

The effect of different retraining intervals for immediate life support training: A randomized controlled trial

BACKGROUND

The optimal retraining intervals for Immediate Life Support (ILS) are unclear. This study aimed to explore the effects of different retraining intervals for simulation-based, short-duration ILS courses.

METHODS

In this randomized controlled study, junior residents and nurses were recruited and assigned to three groups. After receiving initial simulation-based ILS training, the groups underwent retraining at different intervals: 3 months, 6 months, and 1 year. Each one-hour retraining session included an 8-min in-situ resuscitation simulation on a high-fidelity manikin, followed by debriefing. One year after the initial training, all participants completed a paper-based test and self-efficacy questionnaires on teamwork performance, in addition to a resuscitation simulation. Blinded evaluators assessed performance by reviewing simulation videos using validated checklists.

RESULTS

Eighty-two out of 89 participants completed the study. They had similar characteristics, including age and years of work experience. The 6-month group had fewer resuscitation experiences in the past year. One year after the initial training, there were significant differences in the median skill performance scores across the groups (3-month vs. 6-month vs. 1-year: 31 vs. 28 vs. 23.5, p < 0.01). The 3-month group outperformed the 6-month group (p = 0.04), and the 6-month group outperformed the 1-year group (p = 0.01). The 3-month group also had significantly higher knowledge scores and performed best in self-evaluated teamwork performance.

CONCLUSION

Our study shows that a 3-month retraining interval achieved the greatest effect for healthcare professionals with limited resuscitation experience in simulation-based, short-duration ILS retraining courses.

Impact of visual distraction on neonatal mask ventilation: a simulation-based eye-tracking study

OBJECTIVE

This study aimed to investigate whether distractions during simulated neonatal resuscitation impact mask leakage and visual gaze patterns during positive pressure ventilation (PPV) of a newborn manikin.

STUDY DESIGN

In this observational, simulation-based study, medical students and paediatric residents managed a neonate requiring resuscitation alongside a standardised team and executed PPV on a leak-free manikin. The scenario incorporated distractions such as chest compressions, preparation and insertion of an umbilical vein catheter, administering fluids and interpreting venous blood gas. Ventilation parameters were monitored using a respiratory function monitor, and participants were equipped with eye-tracking glasses to assess visual gaze patterns. Additionally, they self-assessed their level of distractions and estimated performance. Measures included dwell time, mask leak, minute volume and respiratory rate to determine whether PPV parameters and distractors were associated during times of interest (TOI).

RESULTS

We included 30 participants and observed statistically significant differences in the delivery of PPV parameters between TOIs with distractions compared with TOIs without distractions, as reflected in mask leak (31.0 vs 15.9 %), minute volume (202.0 vs 253.0 mL/kg/min) and respiratory rate (29.0 vs 33.0/min). Results on alterations in gaze behaviour showed a significant gaze shift from the infant's chest and airway to instruments and other areas of interest when distractions were present. During the venous blood gas interpretation, participants rated their performance worse than during other TOIs. Participants generally overrated their ventilation quality.

CONCLUSION

This study showed a significant impact of distractions on PPV parameters and visual attention during simulated neonatal resuscitation.

Termination of Resuscitation Rules for In-Hospital Cardiac Arrest

Importance

There are no validated decision rules for terminating resuscitation during in-hospital cardiac arrest. Decision rules may guide termination and prevent inappropriate early termination of resuscitation.

Objective

To develop and validate termination of resuscitation rules for in-hospital cardiac arrest.

Design, Setting, and Participants

In this prognostic study, potential decision rules were developed using a national in-hospital cardiac arrest registry from Denmark (data from 2017 to 2022) and validated using registries from Sweden (data from 2007 to 2021) and Norway (data from 2021 to 2022). Six variables (age, initial rhythm, witnessed status, monitored status, intensive care unit location, and resuscitation duration) were considered based on their bedside availability. Prognostic metrics were computed for all possible variable combinations. CIs were obtained using bootstrapping. Rules with a false-positive rate below 1% (predicting death in patients who might otherwise survive) and a positive rate of more than 10% (proportion of all cases for whom termination is proposed) were considered appropriate.

Main Outcomes and Measures

The primary outcome was 30-day mortality.

Results

The cohorts included 9863 Danish, 12 781 Swedish, and 1308 Norwegian patients. The overall median (IQR) age was 74 (66-81) years, 63% were male, and the median (IQR) resuscitation duration was 13 (5-23) minutes. Of 53 864 possible termination rules, 5 were identified as relevant for clinical use. The best performing rule included 4 variables (unwitnessed, unmonitored, initial rhythm of asystole, and resuscitation duration more than or equal to 10 minutes). The rule proposed termination in 110 per 1000 cardiac arrests (positive rate, 11%; 95% CI, 10%-11%) and predicted 30-day mortality incorrectly in 6 per 1000 cases (false-positive rate, 0.6%; 95% CI, 0.3%-0.9%). All 5 rules performed similarly across all 3 cohorts.

Conclusions and Relevance

In this prognostic study, 5 termination of resuscitation rules were developed and validated for in-hospital cardiac arrest. The best performing rule had a low false-positive rate and a reasonable positive rate in all national cohorts. These termination of resuscitation rules may aid decision-making during resuscitation.

Evaluation of interventions in prehospital and in-hospital settings and outcomes for out-of-hospital cardiac arrest patients meeting the termination of resuscitation rule in Japan: A nationwide database study (The JAAM-OHCA Registry)

BACKGROUND

Out-of-hospital cardiac arrest (OHCA) is a global health burden with low survival rates. The termination of resuscitation (TOR) rule, widely adopted internationally, aims to preserve dignity, optimize resources, and protect healthcare providers. However, prehospital TOR is not implemented in Japan, presenting legal and practical challenges. This study analyzes temporal trends in prehospital and in-hospital interventions for OHCA patients with poor predicted outcomes.

METHODS

This retrospective study analyzed data from the Japanese Association for Acute Medicine Out-of-Hospital Cardiac Arrest (JAAM-OHCA) registry (June 2014-December 2021). Adult OHCA patients with medical causes were included if they fulfilled all the advanced life support (ALS) TOR rule criteria: unwitnessed arrest, no return of spontaneous circulation, no bystander-initiated cardiopulmonary resuscitation, and no automated external defibrillator use or defibrillation. Prehospital and in-hospital interventions were evaluated.

RESULTS

Among 11,334 patients meeting the inclusion criteria, 2,447 received all three ALS interventions (advanced airway management, intravenous access, and epinephrine administration). Over time, in-hospital interventions, including endotracheal intubation (56%) and epinephrine administration (82%), decreased, while advanced therapies, including coronary angiography, extracorporeal membrane oxygenation, and targeted temperature management, remained rare (<1%). The median time to TOR after hospital arrival shortened to 18 min. In contrast, prehospital epinephrine administration increased, while advanced airway management and intravenous access decreased.

CONCLUSIONS

OHCA patients who met TOR rule showed a decrease in in-hospital interventions. Further efforts are warranted to avoid futile medical treatments and promote patient-centered care.

Defining the terminology of first responders alerted for out-of-hospital cardiac arrest by medical dispatch centres: An international consensus study on nomenclature

Aim

Emergency medical services target to reduce time to cardiopulmonary resuscitation and defibrillation by alerting additional individuals to out-of-hospital cardiac arrest (OHCA). Multiple terms are used to describe these individuals, potentially causing confusion and hindering comparisons. This international consensus study aimed to establish standardised terminology.

Methods

Forty-six interdisciplinary researchers from four continents participated in a symposium on "Community First Responders" with the objective of standardising relevant terminology. Initially, terms were proposed anonymously for individuals alerted during work hours and those alerted during leisure time. Each term was rated on a 5-point Likert scale. Terms receiving a high level of agreement were included in the final voting process.

Results

Seven terms were suggested for individuals alerted during work hours. In the first voting "first responder", "professional first responder", and "on-duty first responder" achieved high agreement. Ultimately, consensus was reached on the term "on-duty first responder".For individuals alerted during leisure time, ten terms were proposed. Among these, "first responder", "citizen first responder", "community emergency responder", "community first responder", "volunteer first responder", "volunteer responder", and "volunteer community first responder" reached high agreement. In the final vote "community first responder" was selected.The consensus group agreed that the overarching term "first responder" should be used to describe all community-based individuals, who are alerted, regardless of whether they are on duty or off duty.

Conclusion

This consensus study recommends using the terms "on-duty first responder" and "community first responder" to describe individuals additionally alerted by medical dispatch centres to facilitate early intervention in OHCA.

Enhancing trauma cardiopulmonary resuscitation simulation training with the use of virtual reality (Trauma SimVR): Protocol for a randomized controlled trial

BACKGROUND

With the increasing availability and use of digital tools such as virtual reality in medical education, there is a need to evaluate their impact on clinical performance and decision-making among healthcare professionals. The Trauma SimVR study is investigating the efficacy of virtual reality training in the context of traumatic in-hospital cardiac arrest.

METHODS AND ANALYSIS

This study protocol (clinicaltrials.gov identifier: NCT06445764) for a single-center, prospective, randomized, controlled trial focuses on first-year residents in anesthesiology/intensive care, traumatology, and emergency medicine. The study will compare the clinical performance in a simulated scenario between participants who received virtual reality training and those who received traditional e-learning courses for preparation. The primary endpoint is the time to a predefined intervention to treat the underlying cause of the simulated traumatic cardiac arrest. Secondary endpoints include protocol deviations, cognitive load during simulated scenarios, and the influence of gender and personality characteristics on learning outcomes. The e-learning and the virtual reality training content will be developed in collaboration with experts from various medical specialties and nursing, focusing on procedural processes, guideline adherence specific to trauma patient care, and traumatic in-hospital cardiac arrest.

RESULTS

The results of this study will provide valuable insights into the efficacy of virtual reality training, contributing to the advancement of medical education, and serve as a foundation for future research in this rapidly evolving field.

The impact of rhythm perception on chest compression rate during CPR: Insights from a pilot simulation study

Objective

This pilot study aims to assess how individuals with rhythm perception, particularly musicians, are able to maintain the predefined chest compression rate during cardiopulmonary resuscitation compared to people without rhythm perception.

Methods

The study was conducted at the Pilsen Emergency Medicine Conference (Czechia) using a simulation-based cohort design. Participants performed chest compressions on a manikin for 120 s, with the first 10 s guided by a metronome. Participants were grouped based on self-reported rhythmic perception, such as playing a musical instrument. The primary outcome was the average chest compression rate per minute.

Results

A total of 67 participants were included. Both groups provided chest compression rate within the recommended limits. Musicians maintained a better chest compression rate (mean 110.56 compressions per minute) compared to nonmusicians (mean 107.31; T-test, p = 0.00074). Those with any rhythmic perception experience also performed better (T-test, p = 0.036931). Secondary factors, including gender, clinical experience, and prior resuscitation training, did not significantly affect the results.

Conclusion

This study demonstrates that individuals with rhythm perception, especially musicians, follow the predefined frequency of chest compressions more effectively.

The Creation of Shared Mental Models in Simulation Training Enhances Quality of Resuscitation: A Randomized Controlled Study

OBJECTIVES

This study aimed to enhance the quality of Advanced Cardiac Life Support (ACLS) training, with quality defined as the combination of technical skills (TS) and non-technical skills (NTS), by addressing the gap in effective methods for developing NTS through simulation-based medical education (SBME). Specifically, it sought to develop and evaluate a strategy for establishing shared mental models (SMM) and fostering trust among team members during undergraduate emergency training.

METHODS

This study was conducted during mandatory ACLS undergraduate simulation training sessions. The control group participated in traditional, teacher-led classes and debriefings, while the intervention group received training incorporating SMM as the intervention. The study evaluated the quality of cardiopulmonary resuscitation as the primary outcome, encompassing both TS and NTS. Additionally, changes in undergraduate situational motivation, assessed within the framework of self-determination theory, and subjective learning gains were analyzed.

RESULTS

The control group demonstrated a significant improvement in TS (P = .030), while the intervention group did not (P = .078). Conversely, the intervention group showed a significant improvement in NTS (P = .01; 95% confidence interval [0.296, 2.17]), whereas the control group did not (P = .105). The motivational changes of both groups were comparable, reflecting high levels of autonomous motivation. Both groups also reported significant learning gains.

CONCLUSION

This study demonstrates that SBME is highly effective for teaching TS. However, it is crucial to incorporate advanced instructional methods focusing on NTS. One promising approach is the development of SMM. Based on our results, hands-on practice remains essential and should not be restricted to theoretical or conceptual training. A balanced combination of advanced didactic techniques and practical application ensures that learners develop both, TS and NTS. SBME and the development of SMM equally address both the motivational and content dimensions of learning, enhancing student engagement while effectively conveying essential knowledge and skills.

Cardiopulmonary resuscitation coaching for resuscitation teams: A systematic review

Aim

Cardiopulmonary resuscitation (CPR) quality is often substandard to guidelines for resuscitation teams. We aimed to investigate if the use of a CPR coach as part of the resuscitation team can improve teamwork, quality of care, and patient outcomes during simulated and clinical cardiac arrest resuscitation.

Methods

We searched PubMed, Embase, and Cochrane from inception until October 9, 2024 for randomized trials and observational studies. We assessed risk of bias using Cochrane tools and assessed the certainty of evidence using the Grading of Recommendations Assessment, Development and Evaluation approach. PROSPERO CRD42024603212.

Results

We screened 505 records and included 7 studies. Overall, 6 were randomized studies involving pediatric resuscitation of which 4 studies were secondary analyses of one simulation-based trial, and one was an observational study on adult out-of-hospital cardiac arrest. Reported outcomes were: CPR performance in a simulated setting (n = 3), workload in a simulated setting (n = 2), adherence to guidelines in a simulated setting (n = 1), team communication in a simulated setting (n = 1), and clinical CPR performance (n = 1). All studies suggested improved CPR quality and guideline adherence when using a CPR coach compared to not using a coach. Risk of bias varied from low to critical and the certainty of evidence across outcomes was low or very low.

Conclusions

We identified low- to very-low certainty of evidence supporting the use of a CPR coach as part of the resuscitation team in order to improve CPR quality and guideline adherence. However, further research is needed, in particular for clinical performance and patient outcomes.

Kids save lives: Who should train schoolchildren in resuscitation? A systematic review

Aim

CPR training for schoolchildren to increase bystander CPR-rates is widely applied. HCPs are regarded as the instructor gold standard, but using non-HCP instructors (e.g., peer-tutors, schoolteachers, medical students) challenges that. This systematic review assesses whether cardiopulmonary resuscitation (CPR) training for children led by peer-tutors, schoolteachers, or medical students results in different learning outcomes to training by health-care professionals (HCPs).

Methods

We searched studies that compared CPR training for schoolchildren (population) delivered by peer-tutors, schoolteachers, or medical students (intervention), with training led by HCPs (comparison), assessing student knowledge, skills, willingness and/or confidence to perform CPR (outcome). We included randomized and non-randomized controlled trials (study design). Medline, Embase, Psychinfo, Cinahl, Cochrane, Scopus, Web of Science, and Eric were searched from inception until December 23rd, 2023 (timeframe). Two independent reviewers performed title, abstract, full text screening, bias assessment, and grading of certainty of evidence. We followed the Preferred Reporting Items for a Systematic Review and Meta-Analysis (PRISMA) guidelines, and registered the review with PROSPERO.

Results

Of 9'092 studies identified, 14 were included. Comparison of intervention groups to HCP-led training showed similar overall results (knowledge, skills, self-confidence). Superior results for HCP training were only reported for 'ventilation volume', while schoolteachers and medical students achieved superior knowledge transfer. A meta-analysis was possible for 'compression depth' between peer-tutors and HCPs showing no significant differences. Certainty of evidence was 'low' to 'very low'.

Conclusion

This systematic review of CPR training for school children revealed that peer-tutors, schoolteachers and medical students achieve similar educational outcomes compared to those of HCPs. Non-HCPs training schoolchildren is an appropriate cost-efficient alternative and easy to implement in school curricula.

Barriers and Willingness to Undertake Cardiopulmonary Resuscitation Reported by Medical Students Dependent on Their Place of Residence-A Single-Center Study

Background

Bystander-administered cardiopulmonary resuscitation (CPR) is crucial for the survival of out-of-hospital cardiac arrests. However, only roughly 58% of bystanders would provide CPR, with wide variations across different regions. Identifying each factor affecting the barrier or readiness to perform resuscitation is a significant challenge for researchers. This study aimed to evaluate the obstacles preventing first-year medical students from initiating CPR, focusing on the size of domestic residential environments and the time and methodology of practical training.

Methods

The original online questionnaire surveyed first-year medical students at the Medical University of Łódź from February 1 to March 2, 2024. The questionnaire development involved a literature review, expert evaluation, and pilot testing. Participation was voluntary and anonymous, with strict inclusion and exclusion criteria. The data were analyzed using PQStat software, employing descriptive statistics.

Results

The study revealed that 271 medical students reported a similar median of barriers regardless of the place of residence (median (Me) = 5, interquartile range (IQR) 2-6.25 vs. Me = 4, IQR 3-6 vs. Me = 4, IQR 3-6, p = 0.620). Out of 18 analyzed barriers, the only significant difference was found for crowded places. Medical students living in cities most frequently reported a willingness to perform CPR with rescue breaths for all victims. Those who grew up in towns <100,000 residents were less willing to start CPR if an unknown adult were the victim (rural area: 39.2% vs. town: 17.6% vs. city: 45.1%, p < 0.01). The number of reported barriers was similar regardless of training type and the time since training; however, the nature of these barriers varied after a year passed.

Conclusions

Respondents across various locations reported similar number and types of barriers to performing CPR, including the most commonly declared fear of harm, uncertainty about recognizing cardiac arrest, and concerns about disease transmission. Although differences connected to the type of victims were observed, its low or moderate practical significance needs more comprehensive research on the impact of the size of the place of residence on the willingness to perform resuscitation and the related barriers.

The use of the objective structured clinical examination to evaluate paediatric cardiopulmonary resuscitation skills in medical students and measures to improve training

BACKGROUND

The main objectives of the study were to analyse the use of the Objective Structured Clinical Examination (OSCE) to evaluate the skills of medical students in paediatric basic life support (PBLS), to compare two resuscitation training models and to evaluate the measures to improve the teaching program.

METHODS

Comparative, prospective, observation study with intervention in two hospitals, one undergoing a PILS course (Paediatric Immediate Life Support) and another PBLS. The study was performed over three phases. 1º. PBLS OSCE in 2022 three months after the resuscitation training 2. Measures to improve the training program in 2023 3. PBLS OSCE in 2023. Overall results were analysed and comparison between both sites and those for 2022 and 2023 were made.

RESULTS

A total of 210 and 182 students took part in the OSCE in 2022 and 2023, respectively. The overall mean score out of 100 was 83.2 (19), 77.8 (19.8) in 2022 and 89.5 (15.9) and 2023, P < 0.001. Overall cardiopulmonary resuscitation (CPR) effectiveness was adequate in 79.4% and 84.6% of students in 2022 and 2023, respectively. The results of hospital students undergoing a PILS course were better (86.4 (16.6) than those undergoing a PBLS. 80.2 (20.6) p < 0.001. The results from both hospitals improved significantly in 2023.

CONCLUSIONS

The OSCE is a valid instrument to evaluate PBLS skills in medical students and to compare different training methods and program improvements. Medical students who receive a PILS attain better PBLS skills than those who undergo a PBLS course.

Leadership factors for cardiopulmonary resuscitation for clinicians in-hospital; behaviours, skills and strategies: A systematic review and synthesis without meta-analysis

AIM

To identify leadership factors for clinicians during in-hospital cardiopulmonary resuscitation.

DESIGN

Systematic review with synthesis without meta-analysis.

METHODS

The review was guided by SWiM, assessed for quality using CASP and reported with PRISMA.

DATA SOURCES

Cochrane, EMBASE, PubMed, Medline, Scopus and CINAHL (years of 2013-2023) and a manual reference list search of all included studies.

RESULTS

A total of 60 papers were identified with three major themes of useful resuscitation leadership; 'social skills', 'cognitive skills and behaviour' and 'leadership development skills' were identified. Main factors included delegating effectively, while being situationally aware of team members' ability and progress during resuscitation, and being empathetic and supportive, yet 'controlling the room' using a hands-off style. Shared decision-making to reduce cognitive load for one leader was shown to improve effective teamwork. Findings were limited by heterogeneity of studies and inconsistently applied tools to measure leadership.

CONCLUSION

Traditional authoritarian leadership styles are not wanted by team members with preference for shared leadership and collaboration. Balancing this with the need for team members to see leaders in 'control of the room' brings new challenges for leaders and trainers of resuscitation.

IMPLICATIONS FOR NURSING PROFESSION

All clinicians need effective leadership skills for cardiopulmonary resuscitation in-hospital. Nurses provide first response and ongoing leadership for cardiopulmonary resuscitation. Nurses typically display suitable skills that align with useful resuscitation leader factors.

IMPACT

What were the main findings? Collaboration rather than an authoritarian approach to leadership is preferred by team members. Nurses are suitable to 'control the room'. Restricting resuscitation team size will manage disruptive behaviour of team members.

[Maintenance of chest compressions skill in cardiopulmonary resuscitation in primary health care professionals: Quasi-experimental study]

OBJECTIVE

To validate the efficacy of brief CPR training with dual feedback to maintain the ability to perform quality chest compressions.

MATERIALS AND METHODS

Quasi-experimental study with two groups to evaluate a brief theoretical training followed by a practice with manikin with feedback; Participants: 155 health and non-health professionals from 5 primary care health centers of urban area (43 losses); Main measurements: Characteristics of compressions that were measured before and after the brief training and their maintenance at 3 and 6 months according to the study group. The effect of training and maintenance of skills were analyzed using multiple linear regression models.

RESULTS

155 participants were included, mean age 39.7 years (SD=12.0) with 82.7% female. The training effect had an improvement in mean compression depth (pre-post difference: 3.5, P<.001), total compressions with adequate depth (pre-post difference: 0.2, P<.001) and Total Compressions with Adequate Rhythm (pre-post difference: 0.4, P<.001). The second phase was completed by 112 participants (72.2%). Compression skills declined at 3 months and were lower at 6 months, although the loss of skills was not statistically significant between the two groups.

CONCLUSIONS

An individualized, brief training action with feedback immediately improves the quality of compressions. The progressive loss of skills from 3 to 6 months is not relevant.

Cardiac arrest centres for patients with non-traumatic cardiac arrest: A systematic review

INTRODUCTION

Regionalisation and organised pathways of care using specialist centre hospitals can improve outcomes for critically ill patients. Cardiac arrest centre hospitals (CAC) may optimise the delivery of post-resuscitation care. The International Liaison Committee on Resuscitation (ILCOR) has called for a review of the current evidence base.

AIM

This systematic review aimed to assess the effect of cardiac arrest centres for patients with non-traumatic cardiac arrest.

METHODS

Articles were included if they met the prospectively registered (PROSPERO) inclusion criteria. These followed the PICOST framework for ILCOR systematic reviews. A strict definition for a CAC was used, reflecting current position statements and clinical practice. MEDLINE, Embase and the Cochrane Library were searched using pre-determined criteria from inception to 31 December 2023. Risk of bias was assessed using Cochrane's Risk of Bias tool and ROBINS-I. The certainty of evidence for each outcome was assessed using the GRADE approach. Substantial heterogeneity precluded meta-analysis and a narrative synthesis with visualisation of effect estimates in forest plots was performed.

RESULTS

Sixteen studies met eligibility criteria, including data on over 145,000 patients. One was a randomised controlled trial (RCT) at low risk of bias and the remainder were observational studies, all at moderate or serious risk of bias. All studies included adults with out-of-hospital cardiac arrest. One study used initial shockable rhythm as an inclusion criterion and most studies (n = 12) included patients regardless of prehospital ROSC status. Two studies, including the RCT, excluded patients with ST elevation. Survival to hospital discharge with a favourable neurological outcome was reported by 11 studies and favoured CAC care in all observational studies, but the RCT showed no difference. Survival to 30 days with a favourable neurological outcome was reported by two observational studies and favoured CAC care in both. Survival to hospital discharge was reported by 13 observational studies and generally favoured CAC care. Survival to 30 days was reported by two studies, where the observational study favoured CAC care, but the RCT showed no difference.

CONCLUSION

This review supports a weak recommendation that adults with out-of-hospital cardiac arrest are cared for at CACs based on very low certainty of evidence. Randomised evidence has not confirmed the benefits of CACs found in observational studies, however this RCT was a single trial in a very specific setting and a population without ST elevation on post-ROSC ECG. The role of CACs in shockable and non-shockable subgroups, direct versus secondary transfer, as well as the impact of increased transport time and bypassing local hospitals remains unclear.

Early point-of-care echocardiography as a predictive factor for absence of return of spontaneous circulatory in out-of-hospital cardiac arrests: A multicentre observational study

INTRODUCTION

Early assessment of the prognosis of a patient in cardiac arrest during cardiopulmonary resuscitation is highly challenging. This study aims to evaluate the predictive outcome value of early point-of-care ultrasound (POCUS) in out-of-hospital settings.

METHODS

This observational, prospective, multicentre study's primary endpoint was the positive predictive value (PPV) of POCUS cardiac standstill within the first 12 min of advanced life support (ALS) initiation in determining the absence of return of spontaneous circulation (ROSC). A multivariate logistic regression model was constructed with adjustments for known predictive variables typically used in termination of resuscitation (TOR) rules.

RESULTS

A total of 293 patients were analysed, with a mean age of 66.6 ± 14.6 years, and a majority were men (75.8%). POCUS was performed on average 7.9 ± 2.6 min after ALS initiation. Among patients with cardiac standstill (72.4%), 16.0% achieved ROSC compared with 48.2% in those with visible cardiac motions. The PPV of early POCUS cardiac standstill for the absence of ROSC was 84.0%, 95% CI [78.3-88.6]. In multivariable analysis, only POCUS cardiac standstill (adjusted odds ratio [aOR] 3.89, 95% CI [1.86-8.17]) and end-tidal CO2 (ETCO2) value ≤37 mmHg (aOR 4.27, 95% CI [2.21-8.25]) were associated with the absence of ROSC.

CONCLUSION

Early POCUS cardiac standstill during CPR for out-of-hospital cardiac arrest was a reliable predictor of the absence of ROSC. However, its presence alone was not sufficient to determine the termination of resuscitation efforts.

Teaching team competencies within resuscitation training: A systematic review

Objectives

To evaluate the effectiveness of life support training with specific emphasis on team competencies on clinical and educational outcomes.

Methods

This systematic review was prospectively registered (PROSPERO CRD42023473154) and followed the PICOST (population, intervention, comparison, outcome, study design, timeframe) format. All randomized controlled trials and non-randomized studies evaluating learners undertaking life support training with specific emphasis on team competencies in any setting (actual and simulated resuscitations) were included. Unpublished studies were excluded. Medline, Embase and Cochrane databases as well as trial registries were searched from inception to August 2023 (updated January 18, 2024). Two researchers performed title and abstract screening, full-text screening, data extraction, assessment of risk of bias (using RoB2 and ROBINS-I) and certainty of evidence (using GRADE). PRISMA reporting checklist was used to report the results. No funding was obtained to perform this systematic review.

Results

The literature search identified 5470 manuscripts. After the removal of 2073 duplicates, reviewing the remaining articles' titles and abstracts yielded 31 articles for full-text review. Of these, 17 studies were finally included. The studies involved the following training levels: basic life support, adult advanced life support, paediatric and neonatal resuscitations. Most studies (n = 16) evaluated outcomes in simulated, and only one study in actual resuscitations. Studies included in all training contexts showed either neutrality and/or benefits of life support training with specific emphasis on team competencies. Team competencies training improved CPR skill performance and CPR quality. Specific team competencies that improved included leadership, communication, decision-making and task management. No undesirable effects were observed. Meta-analysis was not possible due to significant methodological heterogeneity. Sub-group analysis was impossible due to lack of data. Risk of bias assessment ranged from some concerns to serious. Overall certainty of evidence was rated as low to very low due to risk of bias and imprecision.

Conclusion

This systematic review identified very low and low certainty evidence, almost entirely derived from simulation studies. The studies and their findings were heterogenous but suggest that teaching team competencies can improve resuscitation skills performance and CPR quality, as well as improve team competencies, specifically leadership, communication, decision-making, and task management. Further research is required to understand optimal configuration of team competencies training interventions and to understand the effect on clinical outcomes and cost-effectiveness.

New method for autonomous learning of BLS psychomotor skills: Pillow mannequin: Randomized controlled study

BACKGROUND

Evidence supporting the benefits of autonomous learning of basic life support, such as rapid outcomes and cost-effectiveness, is increasing. Reports supporting the autonomous learning of cognitive skills in basic life support exist. However, there is currently no report supporting the autonomous learning of psychomotor skills in basic life support.

AIM

This study aimed to assess how using a research-developed pillow-made mannequin affects autonomous learning of psychomotor skills in basic life support training.

DESIGN

Randomized controlled trial.

SETTING

This study was conducted in a nursing school in Turkey.

PARTICIPANTS

Sixty-one (n = 61) third-year formal science undergraduate students.

METHODS

At XXX University, 61 nursing students were divided into Intervention (n = 31) and Control Groups (n = 30). Students in both groups received basic life support training, including live demonstrations. Intervention Group students practiced with the mannequin for 15 days. Skill assessments were conducted by two independent evaluators using a real mannequin 15 days later and six months later. Researchers used a checklist to assess psychomotor skills.

RESULTS

The sociodemographic characteristics of both student groups were similar. There was no significant difference in cognitive knowledge levels after the blended training (p > 0.05). However, at both post-intervention assessments, after 15 days and after 6 months, significant skill differences emerged in "placing the index finger on the ends of the sternum," "combining the thumbs in the middle," "defining the lower sternum as a massage point," "placing the base of the chest" "placing the weaker hand at the massage point," "placing the body perpendicular to the ribcage," and "performing 30 compressions." Cohen's kappa value was calculated as 0.932.

CONCLUSION

Use of the mannequin facilitates autonomous learning of psychomotor skills and promotes accurate application.

Cognitive aids used in simulated resuscitation: A systematic review

Objectives

To compare the effectiveness of cognitive aid use during resuscitation with no use of cognitive aids on cardiopulmonary resuscitation quality and performance.

Methods

This systematic review followed the PICOST format. All randomised controlled trials and non-randomised studies evaluating cognitive aid use during (simulated) resuscitation were included in any setting. Unpublished studies were excluded. We did not include studies that reported cognitive aid use during training for resuscitation alone. Medline, Embase and Cochrane databases were searched from inception until July 2019 (updated August 2022, November 2023, and 23 April 2024). We did not search trial registries. Title and abstract screening, full-text screening, data extraction, risk of bias assessment (using RoB2 and ROBINS-I), and certainty of evidence (using GRADE) were performed by two researchers. PRISMA reporting standards were followed, and registration (PROSPERO CRD42020159162, version 19 July 2022) was performed. No funding has been obtained.

Results

The literature search identified 5029 citations. After removing 512 duplicates, reviewing the titles and abstracts of the remaining articles yielded 103 articles for full-text review. Hand-searching identified 3 more studies for full-text review. Of these, 29 studies were included in the final analysis. No clinical studies involving patients were identified. The review was limited to indirect evidence from simulation studies only. The results are presented in five different populations: healthcare professionals managing simulated resuscitations in neonates, children, adult advanced life support, and other emergencies; as well as lay providers managing resuscitations. Main outcomes were adherence to protocol or process, adherence to protocol or process assessed by performance score, CPR performance and retention, and feasibility of chatbot guidance. The risk of bias assessment ranged from low to high. Studies in neonatal, paediatric and adult life support delivered by healthcare professionals showed benefits of using cognitive aids, however, some studies evaluating resuscitations by lay providers reported undesirable effects. The performance of a meta-analysis was not possible due to significant methodological heterogeneity. The certainty of evidence was rated as moderate to very low due to serious indirectness, (very) serious risk of bias, serious inconsistency and (very) serious imprecision.

Conclusion

Because of the very low certainty evidence from simulation studies, we suggest that cognitive aids should be used by healthcare professionals during resuscitation. In contrast, we do not suggest use of cognitive aids for lay providers, based on low certainty evidence.

Comparison of Effectiveness of Two Different Practical Approaches to Teaching Basic Life Support and Use of an Automated External Defibrillator in Primary School Children

Background and Objectives: As the first three links of the chain of survival of victims of cardiac arrest depend on prompt action by bystanders, it is important to educate as much of the population as possible about basic life support and use of an automatic external defibrillator (BLS and AED). Schoolchildren are an accessible population that can be easily taught and numerous BLS and AED courses are available. The aim of this study was to assess the effectiveness of two different practical approaches to teaching BLS and AED. Material and Methods: We compared two different BLS and AED courses (course A and B) offered to 280 eighth- and ninth-grade students in primary schools. Knowledge about and the intention to perform BLS and AED were evaluated using validated questionnaires before and after the courses. Descriptive methods were used to describe the results. To compare courses, we used the Mann-Whitney U test. A p value of <0.05 was considered statistically significant. Results: Differences in knowledge and intention to perform BLS and AED after the courses were significant between courses (p < 0.001 and p = 0.037, respectively). After course A, students demonstrated significantly better knowledge and numerically greater intention to perform BLS and AED (intention score 6.55 ± 0.61 out of 7). Conclusions: Courses in which students have the opportunity to individually practice BLS skills show a greater increase in knowledge and in intention to perform BLS and AED.

Improving Outcomes After Post-Cardiac Arrest Brain Injury: A Scientific Statement From the International Liaison Committee on Resuscitation

This scientific statement presents a conceptual framework for the pathophysiology of post-cardiac arrest brain injury, explores reasons for previous failure to translate preclinical data to clinical practice, and outlines potential paths forward. Post-cardiac arrest brain injury is characterized by 4 distinct but overlapping phases: ischemic depolarization, reperfusion repolarization, dysregulation, and recovery and repair. Previous research has been challenging because of the limitations of laboratory models; heterogeneity in the patient populations enrolled; overoptimistic estimation of treatment effects leading to suboptimal sample sizes; timing and route of intervention delivery; limited or absent evidence that the intervention has engaged the mechanistic target; and heterogeneity in postresuscitation care, prognostication, and withdrawal of life-sustaining treatments. Future trials must tailor their interventions to the subset of patients most likely to benefit and deliver this intervention at the appropriate time, through the appropriate route, and at the appropriate dose. The complexity of post-cardiac arrest brain injury suggests that monotherapies are unlikely to be as successful as multimodal neuroprotective therapies. Biomarkers should be developed to identify patients with the targeted mechanism of injury, to quantify its severity, and to measure the response to therapy. Studies need to be adequately powered to detect effect sizes that are realistic and meaningful to patients, their families, and clinicians. Study designs should be optimized to accelerate the evaluation of the most promising interventions. Multidisciplinary and international collaboration will be essential to realize the goal of developing effective therapies for post-cardiac arrest brain injury.

Addressing out-of-hospital cardiac arrest with current technology advances: Breaking the deadlock with a mobile network

Out-of-hospital cardiac arrest (OHCA) is a global public health problem, with survival rates remaining low at around 10% or less despite widespread cardiopulmonary resuscitation (CPR) training and availability of automated external defibrillators (AEDs). This is partly due to the challenges of knowing when and where a sudden OHCA occurs and where the nearest AED is located. In response, countries around the world have begun to use network technology-based smartphone applications. These applications are activated by emergency medical service dispatchers and alert preregistered volunteer first responders (VFRs) to nearby OHCAs using Global Positioning System localization. Accumulating evidence, although mostly from observational studies, shows their effectiveness in increasing the rate of bystander CPR, defibrillation, and patient survival. Current guidelines recommend the use of these VFR alerting systems, and the results of ongoing randomized trials are awaited for further dissemination. This article also proposed the concept of a life-saving mobile network (LMN), which uses opportunistic network and wireless sensor network technologies to create a dynamic mesh network of potential victims, rescuers, and defibrillators. The LMN works by detecting a fatal arrhythmia with a wearable sensor device, localizing the victim and the nearest AED with nearby smartphones, and notifying VFRs through peer-to-peer communication. While there are challenges and limitations to implementing the LMN in society, this innovative network technology would reduce the tragedy of sudden cardiac death from OHCA.

Pedagogical Implementation of Directive Feedback Manikins on Cardiopulmonary Resuscitation (CPR) Competencies: Expert Versus Peer Coaching

BACKGROUND

Directive feedback manikins in resuscitation training evolved faster than the pedagogical evidence. Educators and learning systems must seek clarification on the efficacy of this technology to have evidence-based practices. This project explores directive feedback device use in cardiopulmonary resuscitation (CPR) education for laypersons.

METHODS

A prospective nonrandomized-controlled design assessed two pedagogical approaches of directive feedback manikins in adult CPR lessons. The 230 participants were distributed between three groups: a control group without directive feedback manikins (no lights, NL), an expert coaching (EC) group with directive feedback and educator interpretation, and a peer coaching (PC) group with directive feedback, peer interpretation, and expert quality assurance.

RESULTS

From the 25 courses observed, average compression depth (mm) did not differ between groups (p = .498), average compression rate (compressions: minute) significantly differed between groups (p = .004), and correct hand placement did not differ between groups (p = .249). A chi-square test showed no significant association between groups and CPR skill feedback, or between groups and "recommending the course to a friend or family member." The PC group was more likely to agree that they could "coach someone to do CPR skills" than the NL or EC.

CONCLUSIONS

This study expands the knowledge base of directive feedback manikins in a pedagogical setting to improve CPR competencies. Training organizations may consider any of these practices effective, choosing those that align with desired outcomes. CPR educators need orientation to feedback devices as well as professional development on educational options for their use. Considerations for further research include technology costs, access, and cultural aspects of implementing these tools.

Effects of peer-education training on cardiopulmonary resuscitation knowledge and skill retention of secondary school students: a feasibility study

OBJECTIVES

The need for cardiopulmonary resuscitation (CPR) training dissemination in the community could be resolved by mass school training programmes. However, the availability of instructors remains an unsolved problem. Our purpose was to investigate the effects of three different instructor types: healthcare professionals, schoolteachers and peer students, on CPR skills retention of secondary school students 6 months after training.

DESIGN

The study was designed as a prospective randomised single-blinded controlled trial. The study ended before reaching the target sample size for the schoolteacher arm.

SETTING AND PARTICIPANTS

Students from three different secondary schools in Heraklion, Greece, were recruited to attend CPR training.

INTERVENTIONS

All participants received a manual and a digital video disc demonstrating the CPR/automated external defibrillator (AED) algorithm, followed by hands-on training. They were randomly assigned to receive training by either healthcare professionals, schoolteachers or peer students, who had previously been trained appropriately.

OUTCOME MEASURES

CPR knowledge and skill retention were evaluated immediately (secondary outcome) and 6 months after training (primary outcome), using a knowledge questionnaire, skill checklists and feedback device.

RESULTS

408 students (199 girls - two non-binary) were enrolled in the study with a median age of 13 (IQR 12-14) years. A total of 255 students (125 girls) were reassessed at 6 months. Preliminary analysis of the data revealed no statistically significant differences between the three groups regarding factual knowledge immediately after training (p=0.226) and at 6 months (p=0.867). Immediately after training, more students trained by healthcare professionals or teachers performed safe defibrillation (p<0.000); however, this finding was dissipated at 6-month reassessment (p=0.202). Compliance with the CPR algorithm and the quality of hands-only CPR were not different (p>0.05) among the groups.

CONCLUSIONS

The type of instructor did not affect the CPR knowledge and skill retention of students 6 months after training. Schoolchildren acting as peer instructors could be an effective alternative to healthcare professionals and schoolteachers, although further studies are needed.

Effectiveness of team-focused CPR on in-hospital CPR quality and outcomes

Objective

We sought to identify changes in neurological outcome over time following initial training and subsequent implementation of team-focused CPR in an inpatient setting where responders practice specific roles with emphasis on minimally interrupted chest compressions and early defibrillation.

Methods

This retrospective pre- vs post-intervention study was conducted at an urban 900-bed teaching hospital and Level I Cardiac Resuscitation Center. We included adult patients suffering in-hospital cardiac arrest occurring in non-emergency department and non-intensive care unit areas who received CPR and/or defibrillation. We compared survival with good neurological outcome at time of hospital discharge in the one-year periods before and after implementation of team-focused CPR. To investigate skill degradation, we compared cumulative survival with good neurological outcome in 3-month intervals against the before team-focused CPR baseline. Trained research associates abstracted explicitly defined variables from electronic health records using a standardized form and data dictionary to achieve consistency between collaborators.

Results

Of 296 IHCAs, 207 patients met inclusion criteria and were analyzed. In 104 patients before team-focused CPR initiation, survival with good neurological outcome was 21%. In the 12-month period following team-focused CPR initiation, survival with good neurological outcome was 31% in 101 patients, risk difference 9.9% (95% CI -2 to 22%; p = 0.14). By quarterly time intervals, following team-focused CPR implementation, the cumulative survival with good neurological outcome at 3 months was 42%; at 6 months 37%; at 9 months 31%; and at 12 months 31%.

Conclusion

In our single-institution implementation of team-focused CPR for in-hospital cardiac arrest, outcomes significantly improved at 6 months before declining towards baseline.

The association of recent simulation training and clinical experience of team leaders with cardiopulmonary resuscitation quality during in-hospital cardiac arrest

OBJECTIVE

We aimed to investigate the association of recent team leader simulation training (<6 months) and years of clinical experience (≥4 years) with chest compression quality during in-hospital cardiac arrest (IHCA).

METHODS

This cohort study of IHCA in four Danish hospitals included cases with data on chest compression quality and team leader characteristics. We assessed the impact of recent simulation training and experienced team leaders on longest chest compression pause duration (primary outcome), chest compression fraction (CCF), and chest compression rates within guideline recommendations using mixed effects models.

RESULTS

Of 157 included resuscitation attempts, 45% had a team leader who recently participated in simulation training and 66% had an experienced team leader. The median team leader experience was 7 years [Q1; Q3: 4; 11]. The median duration of the longest chest compression pause was 16 s [10; 30]. Having a team leader with recent simulation training was associated with significantly shorter longest pause durations (difference: -7.11 s (95%-CI: -12.0; -2.2), p = 0.004), a higher CCF (difference: 3% (95%-CI: 2.0; 4.0%), p < 0.001) and with less guideline compliant chest compression rates (odds ratio: 0.4 (95%-CI: 0.19; 0.84), p = 0.02). Having an experienced team leader was not associated with longest pause duration (difference: -1.57 s (95%-CI: -5.34; 2.21), p = 0.42), CCF (difference: 0.7% (95%-CI: -0.3; 1.7), p = 0.17) or chest compression rates within guideline recommendations (odds ratio: 1.55 (95%-CI: 0.91; 2.66), p = 0.11).

CONCLUSION

Recent simulation training of team leaders, but not years of team leader experience, was associated with shorter chest compression pauses during IHCA.

The investigation of the efficiency of basic life support education among high school students: Protocol, design and implementation of an interventional, prospective longitudinal, individually randomised, parallel 1:1 grouped trial

Background

Basic life support (BLS) skills are crucial not only for healthcare workers but for all lay people as well. Timely recognition of out-of-hospital cardiac arrest (OHCA) and the initiation of BLS by bystanders before the arrival of healthcare personnel may improve survival. There are several methods of spreading BLS skills and improve BLS skill retention among lay people. One of these methods can be the education of adolescent school children. The introduction of mandatory BLS education in schools was very effective in some European countries to increase the rate of bystander BLS.

Methods/design

The current study aims to investigate the efficacy of a BLS training and BLS curriculum among high school children in Hungary. Moreover, the investigators would like to optimise factors influencing skill retention in this first responder group and aim to compare two types of teaching methods: feedback given by the instructor or software-based feedback on the efficacy of chest compressions during the course. This study will be an interventional, assessor blinded, individually randomised parallel group trial recruiting 360 students. BLS skill retention will be assessed at the end of the course, two months after the training and six months after training.

Discussion

The current study will increase our knowledge on the methods educating BLS among high school children. The results will help us to create an effective BLS curriculum at schools.Trial registration: ClinicalTrials.gov: NCT06016153. Prospectively registered on 08/2023.

Gamified learning for resuscitation education: A systematic review

Aim

To systematically review published literature to evaluate the impact of gamified learning on educational and clinical outcomes during life support education.

Methods

This systematic review was conducted as part of the continuous evidence evaluation process of the International Liaison Committee on Resuscitation (ILCOR). A search of PubMed, Embase, and Cochrane was conducted from inception until February 12, 2024. Studies examining incorporation of gamified learning were eligible for inclusion. Reviewers independently extracted data on study design and outcomes; appropriate risk of bias assessment tools were used across all outcomes.

Results

2261 articles were identified and screened, yielding sixteen articles (seven randomized trials, nine observational studies) which comprised the final review. No meta-analyses were conducted due to significant heterogeneity of intervention, population, and outcome. Only one study was found to have a low risk of bias; the remaining studies were found to have moderate to high risk. Fourteen studies were in healthcare providers and two were in laypersons. Most studies (11 of 16) examined the impact of a digital platform (computer or smartphone). Most (15 of 16) studies found a positive effect on at least one educational domain; one study found no effect. No included study found a negative effect on any educational domain.

Conclusion

This systematic review found a very heterogeneous group of studies with low certainty evidence, all but one of which demonstrated a positive effect on one or more educational domains. Future studies should examine the underlying causes of improved learning with gamification and assess the resource requirements with implementation and dissemination of gamified learning.

New communication tool for basic life support training: smart glasses. A quasi-experimental study

AIM

To analyze the effectiveness of a teaching-learning methodology for teletraining in basic life support (BLS) based on communication through smart glasses.

DESIGN

Pilot quasi-experimental non-inferiority study.

PARTICIPANTS

Sixty college students.

INTERVENTIONS

Randomization of the participants in: tele-training through smart glasses (SG) and traditional training (C) groups. Both training sessions were very brief (less than 8 min) and included the same BLS content. In SG, the instructor trained through a video call with smart glasses.

MAIN VARIABLES OF INTEREST

The BLS protocol, the use of AED, the quality of resuscitation and the response times were evaluated.

RESULTS

In most of the BLS protocol variables, the resuscitation quality and performance times, there were no statistically significant differences between groups. There were significant differences (in favor of the SG) in the assessment of breathing (SG: 100%, C: 81%; p = 0.013), the not-to-touch warning before applying the shock (SG: 79%, C: 52%; p = 0.025) and compressions with correct recoil (SG: 85%, C: 32%; p = 0.008).

CONCLUSIONS

Laypeople BLS-AED brief tele-training through smart glasses could potentially be, at least, as effective as traditional training methods. In addition, smart glasses could be more advantageous than traditional teaching for certain points of the BLS protocol and chest compressions quality, probably due to the capability of real-time visualization of images which supports the BLS sequence. Augmented reality supported teaching should be considered for BLS training, although caution is required in extrapolating findings, and further in-depth studies are needed to confirm its potential role depending on concrete target populations and environments.

Willingness and Barriers to Undertaking Cardiopulmonary Resuscitation Reported by Medical Students after the SARS-CoV-2 Pandemic-Single-Center Study

Most of the studies in the field of willingness and barriers to resuscitation (CPR) were conducted before the SARS-CoV-2 pandemic. The aim of the study was to assess the number and types of barriers to CPR among medical students after the pandemic ended. This study was based on a survey. The data was collected from 12 April 2022 to 25 May 2022. A total of 509 complete questionnaires were obtained. The number of barriers depending on the time elapsed from the last CPR course did not differ significantly (Me = 4 [IQR 2-6] vs. Me = 5 [IQR 3-7]; p = 0.054, respectively). The number of all barriers reported by respondents differed significantly and was higher in those reporting fear of coronavirus (Me = 4 [IQR 2-6] vs. Me = 7 [IQR 4-9]; p < 0.001, respectively). A total of 12 out of all 23 barriers were significantly more frequent in this group of respondents. Barriers to CPR are still common among medical students, even despite a high rate of CPR training. The pandemic significantly affected both the number and frequency of barriers. The group of strangers and children, as potential cardiac arrest victims, deserve special attention. Efforts should be made to minimize the potentially modifiable barriers.

The effect of standalone audio-visual feedback devices on the quality of chest compressions during laypersons' cardiopulmonary resuscitation training: a systematic review and meta-analysis

AIMS

Individual studies that investigated the effect of standalone audio-visual feedback (AVF) devices during laypersons' cardiopulmonary resuscitation (CPR) training have yielded conflicting results. This review aimed to evaluate the effect of standalone AVF devices on the quality of chest compressions during laypersons' CPR training.

METHOD AND RESULT

Randomized controlled trials of simulation studies recruiting participants without actual patient CPR experience were included. The intervention evaluated was the quality of chest compressions with standalone AVF devices vs. without AVF devices. Databases, such as PubMed, Cochrane Central, Embase, Cumulative Index to Nursing & Allied Health Literature (CINAHL), Web of Science, and PsycINFO, were searched from January 2010 to January 2022. The risk of bias was assessed using the Cochrane risk of bias tool. A meta-analysis alongside a narrative synthesis was used for examining the effect of standalone AVF devices.Sixteen studies were selected for this systematic review. A meta-analysis revealed an increased compression depth of 2.22 mm [95% CI (Confidence Interval), 0.88-3.55, P = 0.001] when participants performed CPR using the feedback devices. Besides, AVF devices enabled laypersons to deliver compression rates closer to the recommended range of 100-120 per min. No improvement was noted in chest recoil and hand positioning when participants used standalone AVF devices.

CONCLUSION

The quality of the included studies was variable, and different standalone AVF devices were used. Standalone AVF devices were instrumental in guiding laypersons to deliver deeper compressions without compromising the quality of compression rates. However, the devices did not improve the quality of chest recoil and placement of the hands.

Exploring cardiac arrest in 'at-home' settings: Concepts derived from a qualitative interview study with layperson bystanders

BACKGROUND

Two thirds of Out-of-Hospital Cardiac Arrests (OHCAs) occur at the patient's home ('at-home-CA'), where bystander CPR (B-CPR) rates are significantly lower than in public locations. Knowledge about the circumstances of this specific setting has mainly been limited to quantitative data. To develop a more conceptual understanding of the circumstances and dynamics of 'at-home CA', we conducted a qualitative interview study.

METHODS

Twenty-one semi-structured in-depth interviews were performed with laypersons who had witnessed 'at-home CA'. The interviews were audio recorded, transcribed, and analysed by qualitative content analysis (QCA). A category system was developed to classify facilitating and impeding factors and to finally derive overarching concepts of 'at-home CA'.

RESULTS

Qualitative Content Analysis yielded 1'347 relevant interview segments. Of these, 398 related to factors facilitating B-CPR, 328 to factors impeding, and 621 were classified neutral. Some of these factors were specific to 'at-home CA'. The privacy context was found to be a particularly supportive factor, as it enhanced the commitment to act and facilitated the detection of symptoms. Impeding factors, aggravated in 'at-home CA' settings, included limited support from other bystanders, acute stress response and impaired situational judgement, as well as physical challenges when positioning the patient. We derived six overarching concepts defining the 'at-home CA' situation: (a) unexpectedness of the event, (b) acute stress response, (c) situational judgement, (d) awareness of the necessity to perform B-CPR, (e) initial position of the patient, (f) automaticity of actions.

CONCLUSION

Integrating these concepts into dispatch protocols and layperson training may improve dispatcher-bystander interaction and the outcomes of 'at-home CA'.

Basic life support training for people with disabilities. A scoping review

Background

The integration of populations with various types of disabilities into basic life support (BLS) training programs could contribute to a potential increase in trained laypersons with BLS knowledge and, consequently, in survival rates. The objective of this study was to analyze the distinct educational methods which exist today on BLS for people with some type of specific disability, and to evaluate their impact on the quality of BLS maneuvers.

Methods

A scoping review in which the different training strategies in BLS for people with distinctive disabilities were analyzed was carried out. Previous studies were sought and researched in MEDLINE, EMBASE, and the Cochrane Library from the beginning up to 4 August 2023.

Results

A total of 14 studies were thoroughly analyzed. The BLS training strategies for people with disabilities were classified according to the following criteria: objective (training, content validation or analysis of learning barriers), target population (visual, hearing, physical disabilities or Down syndrome), training resources (training with/without adaptation), contents (BLS and use of the automated external defibrillator) and evaluation instrument (i.e., the simulation test and knowledge questionnaire). The variety of BLS training programs for such population is limited. Likewise, people with different disabilities are able to effectively learn BLS maneuvers, although with mixed results, mainly in those regarding the CPR quality.

Conclusion

People with visual, hearing disabilities or Down syndrome are able to effectively learn BLS maneuvers.

A roadmap to building first responder networks: Lessons learned and best practices from Belgium and Switzerland

Background/Aims

Limited bystander assistance and delayed emergency medical service arrival reduce the chances of survival in cardiac arrest victims. Early basic life support through trained first responders (FR) and automatic external defibrillation both improve the outcome. Well-organized FR networks have shown promise, but guidance on effective implementation is lacking. This study evaluates two FR networks, in Belgium and in Switzerland, to identify main advancements in the development of such systems.

Method

Direct comparison is made of the barriers and facilitators in the development of both FR systems from 2006 up until December 2022, and summarized within a roadmap.

Results

The Roadmap comprises four integral steps: exploration, installation, initiation, and implementation. Exploration involves understanding the national legislation, engaging with advisory bodies, and establishing local steering committees. The installation phase focuses on FR recruitment, engaging specific professional groups such as firemen, registering public Automated External Defibrillators (AEDs), and requesting feedback. The initiation step includes implementing improvement cycles and fidelity measures. Finally, implementation expands the network, leading to increased survival rates and the integration of these practices into legislation. A significant focus is placed on FR's psychological wellbeing. Moreover, the roadmap highlights the use of efficient geo-mapping to simplify optimal AED placement and automatically assign FRs to tasks.

Conclusion

The importance of FR networks for early resuscitation is increasingly recognized and various systems are being developed. Key developmental strategies of the EVapp and Ticino Cuore app system may serve as a roadmap for other systems and implementations within Europe and beyond.

Attitudes of Asian and Polish Adolescents towards the Use of Ecological Innovations in CPR Training

BACKGROUND

The potential use of manikins made of environmentally friendly materials (biodegradable or easily recycled) could be a milestone in promoting cardiac arrest awareness and mass resuscitation training without the threat of generating large amounts of unprocessable waste. The main aim of the study was to compare the attitude of young adults from Asia and Poland towards cardiopulmonary resuscitation training forms and to evaluate the innovative concept of an ecological resuscitation manikin; Methods: This was a survey-based study conducted during two events in Thailand and Poland in 2023; Results: A total of 226 questionnaires were included in the final analysis. Asian respondents were significantly more likely to choose traditional training than Polish participants (78% vs. 58%, respectively). A manikin that is mainly biodegradable was the most common choice across the entire study group. Young Asians were significantly more likely to choose a traditional stationary course, while Polish respondents were highly significantly more likely to opt for hybrid training (online with practical training provided at the student's home).

CONCLUSIONS

In the total study group, young people from Poland and parts of Asia are most likely to participate in traditional on-site instructor-led training, but a comparison across groups showed a significant tendency for young Poles to choose a hybrid training option, i.e., a combination of online and hands-on training. Despite some differences, both study groups showed a strong interest in pro-environmental behavior and the use of more ecofriendly solutions than previously used in resuscitation training.

Disparities in layperson resuscitation education: A scoping review

BACKGROUND

The aim of this scoping review was to identify factors that would enable or hinder the opportunity for laypersons to undertake resuscitation education.

METHODS

We searched PubMed, Ovid EMBASE, CINAHL, and the Cochrane Central Register of Controlled Trials (CENTRAL) to identify studies published from January 1, 1966 to December 31, 2022 including factors that could influence laypersons to undertake resuscitation education. Data regarding participant characteristics, interventions, and design and outcomes of included studies were extracted.

RESULTS

Of the initially identified 6627 studies, 23 studies (20 cross-sectional and 3 cohort studies) were finally included. Among them, a wide variety of enablers and barriers were identified. High heterogeneity among studies was observed. We categorized factors into three themes: personal factors (age, sex, race, family status, language, prior experience of resuscitation, and immigration status), socioeconomic and educational factors (income, societal status, occupation and legislation, and educational attainment), and geographic factors (birthplace and habitancy). Several barriers were identified that affect laypersons from participating in resuscitation training, such as personal factors like advanced age, lower socioeconomic and educational status, as well as being part of marginalized groups due to race or language barriers. On the other hand, several enablers identified in the study included prior experiences of witnessing someone collapsing, awareness of automated external defibrillators in public locations, certain occupations, or legal requirements for training.

CONCLUSIONS

Various barriers and enablers were found to influence laypersons to participate in resuscitation training. To enhance layperson response to cardiac arrest, targeted initiatives that aim to eliminate barriers need to be initiated, and further research is required to explore factors relating to populations with special needs.

Out of sight - Out of mind? The need for a professional and standardized peri-mission first responder support model

First responders are an essential part of the chain (-mail) of survival as they bridge and reduce the time to first chest compressions and defibrillation substantially. However, in the peri-mission phase before and after being sent to a cardiac arrest, these first responders are in danger of being forgotten and taken for granted, and the potential psychological impact has to be remembered. We propose a standardized first responder support system (FRSS) that needs to ensure that first responders are valued and cared for in terms of psychological safety and continuing motivation. This multi-tiered program should involve tailored education and standardized debriefing, as well as actively seeking contact with the first responders after their missions to facilitate potentially needed professional psychological support.

Learning of Basic Life Support through the Flipped Classroom in Secondary Schoolchildren: A Quasi-Experimental Study with 12-Month Follow-Up

Background and Objectives: International institutions together with the World Health Organisation recommend the teaching of BLS in schools. Therefore, the objective of this research was to study the feasibility of teaching CPR and AED through the flipped classroom, exploring the medium- and long-term retention of knowledge and practical skills among high school students. Materials and Methods: The sample consisted of 260 secondary schoolchildren (137 in the experimental group (EG) and 123 in the control group (CG)) between 12 and 14 years old (M = 12.75 ± 1.02). Results: The data revealed that the EG obtained better post-course results in the correct position of the hands (p = 0.011), the depth of external cardiac compression (p > 0.001), and the mean time to apply an effective shock with the AED (p = 0.013). The CG obtained better results in compressions with complete chest re-expansion (p = 0.025). These differences disappeared at 6 months (p > 0.05) and 12 months (p > 0.05). Conclusions: A training program based on the flipped classroom is as effective and viable as traditional training, although more efficient since it is applied in less time, in the sequence of action in BLS, CPR skills, and the application of an effective shock with an AED.

Guidelines on human factors in critical situations 2023

OBJECTIVE

To provide guidelines to define the place of human factors in the management of critical situations in anaesthesia and critical care.

DESIGN

A committee of nineteen experts from the SFAR and GFHS learned societies was set up. A policy of declaration of links of interest was applied and respected throughout the guideline-producing process. Likewise, the committee did not benefit from any funding from a company marketing a health product (drug or medical device). The committee followed the GRADE® method (Grading of Recommendations Assessment, Development and Evaluation) to assess the quality of the evidence on which the recommendations were based.

METHODS

We aimed to formulate recommendations according to the GRADE® methodology for four different fields: 1/ communication, 2/ organisation, 3/ working environment and 4/ training. Each question was formulated according to the PICO format (Patients, Intervention, Comparison, Outcome). The literature review and recommendations were formulated according to the GRADE® methodology.

RESULTS

The experts' synthesis work and application of the GRADE® method resulted in 21 recommendations. Since the GRADE® method could not be applied in its entirety to all the questions, the guidelines used the SFAR "Recommendations for Professional Practice" A means of secured communication (RPP) format and the recommendations were formulated as expert opinions.

CONCLUSION

Based on strong agreement between experts, we were able to produce 21 recommendations to guide human factors in critical situations.

Dispatch of Volunteer Responders to Out-of-Hospital Cardiac Arrests

BACKGROUND

Systems for dispatch of volunteer responders to collect automated external defibrillators and/or to provide cardiopulmonary resuscitation (CPR) in cases of nearby out-of-hospital cardiac arrest (OHCA) are widely implemented.

OBJECTIVES

This study aimed to investigate whether the activation of a volunteer responder system to OHCAs was associated with higher rates of bystander CPR, bystander defibrillation, and 30-day survival vs no system activation.

METHODS

This was a retrospective observational analysis within the ESCAPE-NET (European Sudden Cardiac Arrest network: Towards Prevention, Education, New Effective Treatment) collaborative research network. Included were cases of OHCA between 2015 and 2019 from 5 European sites with volunteer responder systems. At all sites, systems were activated by dispatchers at the emergency medical communication center in response to suspected OHCA. Exposed cases (system activation) were compared with nonexposed cases (no system activation). Risk ratios (RRs) were calculated for the outcomes of bystander CPR, bystander defibrillation, and 30-day survival after inverse probability treatment weighting. Missing data were handled using multiple imputation.

RESULTS

In total, 9,553 cases were included. In 4,696 cases, the volunteer responder system was activated, and in 4,857 it was not. The pooled RRs were 1.30 (95% CI: 1.15-1.47) for bystander CPR, 1.89 (95% CI: 1.36-2.63) for bystander defibrillation, and 1.22 (95% CI: 1.07-1.39) for 30-day survival.

CONCLUSIONS

Activation of a volunteer response system in cases of OHCA was associated with a higher chance of bystander CPR, bystander defibrillation, and 30-day survival vs no system activation. A randomized controlled trial is necessary to determine fully the causal effect of volunteer responder systems.

Perceived threats and challenges experienced by first responders during their mission for an out-of-hospital cardiac arrest

Aim

No study has systematically captured the perceived threat, discomfort or issues experienced by First Responders (FRs). We aimed to report the FRs' experience during a mission for an out-of-hospital cardiac arrest (OHCA) in a ten-year span.

Methods

We collected all the 40-items questionnaires filled out by the FRs dispatched in Ticino Region (Switzerland) from 01/10/2010 to 31/12/2020. We compared results between FRs alerted by SMS or APP and between professional and citizen FRs.

Results

3391 FRs filled the questionnaire. The OHCA information was considered complete more frequently by FRs alerted by APP (85.6% vs 76.8%, p < 0.001), but a challenge in reaching the location was more frequent (15.5% vs 11.4%, p < 0.001), mainly due to wrong GPS coordinate. The FRs initiated/participated in resuscitation in 64.6% and used an AED in 31.9% of OHCAs, without issue in 97.9%. FRs reported a very high-level of satisfaction (97%) in EMS collaboration, but one-third didn't have the possibility to debrief. Citizen FRs used AED more frequently than professional FRs (34.6% vs 30.7%, p < 0.01), but experienced more often difficulties in performing CPR (2.6% vs 1.2%, p = 0.02) and wore more in need to debrief (19.7% vs 13%, p < 0.01).

Conclusions

We provide a unique picture from the FRs' point of view during a real-life OHCA reporting high-level of satisfaction, great motivation but also the need of systematic debrief. We identified areas of improvements including geolocation accuracy, further training on AED use and support program dedicated to citizen FRs.

Exploring training needs of newly graduated medical doctors to inform the undergraduate simulation-based curriculum: a national Delphi consensus study

PURPOSE

Mastering technical procedures is a key component in succeeding as a newly graduated medical doctor and is of critical importance to ensure patient safety. The efficacy of simulation-based education has been demonstrated but medical schools have different requirements for undergraduate curricula. We aimed to identify and prioritize the technical procedures needed by newly graduated medical doctors.

METHODS

We conducted a national needs assessment survey using the Delphi technique to gather consensus from key opinion leaders in the field. In the first round, a brainstorm was conducted to identify all potential technical procedures. In the second round, respondents rated the need for simulation-based training of each procedure using the Copenhagen Academy for Medical Education and Simulation Needs Assessment Formula (CAMES-NAF). The third round was a final elimination and prioritization of the procedures.

RESULTS

In total, 107 experts from 21 specialties answered the first round: 123 unique technical procedures were suggested. Response rates were 58% and 64% in the second and the third round, respectively. In the third round, 104 procedures were eliminated based on the consensus criterion, and the remaining 19 procedures were included and prioritized. The top five procedures were: (i) insert peripheral intravenous catheter, (ii) put on personal protection equipment, (iii) perform basic airway maneuvers, (iv) perform basic life support, and (v) perform radial artery puncture.

CONCLUSION

Based on the Delphi process a final list of 19 technical procedures reached expert consensus to be included in the undergraduate curriculum for simulation-based education.

Efficiency of virtual reality for cardiopulmonary resuscitation training of adult laypersons: A systematic review

BACKGROUND

Virtual reality (VR) is an interesting and promising way to teach cardiopulmonary resuscitation (CPR) to adult laypersons as its high immersive characteristics could improve the level of skills and acquired knowledge in learning basic life support (BLS).

METHODS

This systematic review assesses current literature about BLS training with VR and its possible effect on CPR-quality parameters, self-efficacy, perceived learning, and learners' satisfaction and short and long-term patients' outcome. We screened the Cochrane Library, PubMed, CINAHL, MEDLINE Ovid, Web of Science, and Scopus databases and included only clinical trials and quasi-experimental studies published from inception to October 1, 2021, which analyzed adult laypersons' BLS training with the use of VR. Primary outcomes were CPR parameters (chest compression rate and depth, Automated External Defibrillator use). Secondary outcomes were self-efficacy, perceived learning and learners satisfaction, and patients' outcomes (survival and good neurologic status). The risk of bias of included study was assessed using the Cochrane Handbook for Systematic Reviews of Interventions tool to evaluate randomized control trials and the transparent reporting of evaluations with nonrandomized designs checklist for nonrandomized studies.

RESULTS

After full article screening, 6 studies were included in the systematic review (731 participants) published between 2017 and 2021. Because of the heterogeneity of the studies, we focused on describing the studies rather than meta-analysis. The assessment of the quality of evidence revealed overall a very low quality. Training with VR significantly improved the rate and depth of chest compressions in 4 out of 6 articles. VR was described as an efficient teaching method, exerting a positive effect on self-efficacy, perception of confidence, and competence in 2 articles.

CONCLUSION

VR in BLS training improves manual skills and self-efficacy of adult laypersons and may be a good teaching method in a blended learning CPR training strategy. VR may add another way to divide complex parts of resuscitation training into easier individual skills. However, the conclusion of this review suggests that VR may improve the quality of the chest compressions as compared to instructor-led face-to-face BLS training.

"Needed but lacked": Exploring demand- and supply-side determinants of access to cardiopulmonary resuscitation training for the lay public in China

Background

Despite years of public cardiopulmonary resuscitation (CPR) training efforts, the training rate and survival following out-of-hospital cardiac arrest (OHCA) have increased modestly in China. Access is imperative to increase the public CPR training rate, which is determined by both demand- (e.g., the lay public) and supply-side (e.g., CPR trainers) factors. We aimed to explore the demand and supply determinants of access to CPR training for the lay public in China.

Methods

Qualitative semi-structured interviews were conducted with 77 laypeople (demand side) and eight key stakeholders from CPR training institutions (supply side) in Shanghai, China. The interview guide was informed by Levesque et al. healthcare access framework. Data were transcribed, quantified, described, and analyzed through thematic content analysis.

Results

On the demand side, the laypeople's ability to perceive their need and willingness for CPR training was strong. However, they failed to access CPR training mainly due to the lack of information on where to get trained. Overestimation of skills, optimism bias, and misconceptions impeded laypeople from attending training. On the supply side, trainers were able to meet the needs of the trainees with existing resources, but they relied on participants who actively sought out and registered for training and lacked an understanding of the needs of the public for marketing and encouraging participation in the training.

Conclusion

Insufficient information and lack of initiative on the demand side, lack of motivation, and understanding of public needs on the supply side all contributed to the persistently low CPR training rate in China. Suppliers should integrate resources, take the initiative to increase the CPR training rate, innovate training modes, expand correct publicity, and establish whole-process management of training programs.
