A nationwide investigation of CPR courses, books, and skill retention

Resuscitation education science meets virtual and augmented reality: Evolution from potential concept to recommendations

Aim of the study

This study aims to examine the evolution of recommendations for integrating Virtual Reality (VR) and Augmented Reality (AR) into adult Basic Life Support (BLS) education over time.

Data sources

In December 2024, we conducted a two-phase search. First, we identified and reviewed publications available on the International Liaison Committee on Resuscitation (ILCOR) webpage, focusing on resuscitation education science, specifically addressing VR and/or AR in adult BLS education. In the second phase, we reviewed the references and citations of the included publication to identify relevant publications from the American Heart Association (AHA), European Resuscitation Council (ERC), and ILCOR.

Results

Across both phases, we included 29 AHA, ERC, and ILCOR publications on resuscitation education. These comprised 16 ILCOR CoSTRs, seven AHA/ERC guidelines (four ERC, three AHA), three ILCOR scientific statements, two AHA scientific statements, and one ILCOR review. The first mention of VR appeared in 2003, but the first recommendation was provided in 2020 AHA guidelines, suggesting its use for adult BLS training based on very low-quality evidence. In 2024, the ILCOR CoSTRs issued a weak recommendation supporting AR and a weak recommendation against VR for adult BLS training, both based on very low-quality evidence.

Conclusion

While VR/AR is gaining traction in resuscitation training, its effectiveness remains debated. Initially focused on professionals, it now extends to laypersons and schoolchildren. However, strong evidence is lacking. Future research should assess learning outcomes, guideline adherence, and patient impact to support stronger ILCOR recommendations.

Strengthening the WHO Emergency Care Systems Framework: insights from an integrated, patient-centered approach in the Copenhagen Emergency Medical Services system-a qualitative system analysis

BACKGROUND

The World Health Organization Emergency Care Systems Framework (WHO ECSF) was designed to offer guidance in establishing and developing effective Emergency Medical Services (EMS) systems. However, evolving disease patterns, changing community needs, and a rising demand for emergency care services, highlight the need for more integrated and patient-centered EMS systems. This evolution should be mirrored in the WHO ECSF. Hence, this study explores system components of the Copenhagen (CPH) EMS that may enhance the WHO ECSF´s emphasis on integrated and patient-centered care.

METHODS

A qualitative case study was conducted from April through June 2021, including (i) semi-structured interviews with researchers and professionals at the CPH EMS and (ii) a scoping literature review using PubMed, Google Scholar, expert recommendations and snowballing.

RESULTS

Thirteen expert interviews and 35 records were analyzed, revealing key integrated care components within the CPH EMS. These include education and citizen participation programs, early triaging, differentiated care pathways coordinated with primary care and out-of-hours services, and specialized mobile care units complementing "traditional" ambulance services. Technology supports integrated and patient-centered care by facilitating early differentiation of care, efficient dispatching, and communication. Data-driven approaches were fostered through technology-aided data collection, supporting research, quality improvement, and patient safety. The identified components were mapped within the WHO ECSF´s four domains: scene, transport, facility, and cross-cutting elements. Due to the prehospital focus of the CPH EMS, limited data was available for the "facility" site.

CONCLUSIONS

The CPH EMS demonstrates an integrated, patient-centered systems approach that emphasizes seamless coordination along the patient care pathway, bridging EMS with broader health and social systems. Research-informed initiatives and intelligent technology solutions underscore the potential for enhancing the WHO ECSF. These findings highlight the importance of continued system integration and a holistic health perspective, including in emergency settings. Further research is needed to assess the transferability of these components across diverse global contexts.

An expert consensus–based checklist for quality appraisal of educational resources on adult basic life support: a Delphi study

Objective

Given the lack of a unified tool for appraising the quality of educational resources for lay-rescuer delivery of adult basic life support (BLS), this study aimed to develop an appropriate evaluation checklist based on a consensus of international experts.

Methods

In a two-round Delphi study, participating experts completed questionnaires to rate each item of a predeveloped 72-item checklist indicating agreement that an item should be utilized to evaluate the conformance of an adult BLS educational resource with resuscitation guidelines. Consensus on item inclusion was defined as a rating of ≥7 points from ≥75% of experts. Experts were encouraged to add anonymous suggestions for modifying or adding new items.

Results

Of the 46 participants, 42 (91.3%) completed the first round (representatives of 25 countries with a median of 16 years of professional experience in resuscitation) and 40 (87.0%) completed the second round. Thirteen of 72 baseline items were excluded, 55 were included unchanged, four were included after modification, and four new items were added. The final checklist comprises 63 items under the subsections “safety” (one item), “recognition” (nine items), “call for help” (four items), “chest compressions” (12 items), “rescue breathing” (12 items), “defibrillation” (nine items), “continuation of CPR” (two items), “choking” (10 items) and “miscellaneous” (four items).

Conclusions

The produced checklist is a ready-to-use expert consensus–based tool for appraising the quality of educational content on lay-rescuer provision of adult BLS. The checklist gives content developers a tool to ensure educational resources comply with current resuscitation knowledge, and may serve as a component of a prospective standardized international framework for quality assurance in resuscitation education.

Geographical Association Between Basic Life Support Courses and Bystander Cardiopulmonary Resuscitation and Survival from OHCA in Denmark

Introduction

Annually, approximately 4% of the entire adult population of Denmark participate in certified basic life support (BLS) courses. It is still unknown whether increases in BLS course participation in a geographical area increase bystander cardiopulmonary resuscitation (CPR) or survival from out-of-hospital cardiac arrest (OHCA). The aim of the study was to examine the geographical association between BLS course participation, bystander CPR, and 30-day survival from OHCA.

Methods

This nationwide register-based cohort study includes all OHCAs from the Danish Cardiac Arrest Register. Data concerning BLS course participation were supplied by the major Danish BLS course providers. A total of 704,234 individuals with BLS course certificates and 15,097 OHCA were included from the period 2016-2019. Associations were examined using logistic regression and Bayesian conditional autoregressive analyses conducted at municipality level.

Results

A 5% increase in BLS course certificates at municipality level was significantly associated with an increased likelihood of bystander CPR prior to ambulance arrival with an adjusted odds ratio (OR) of 1.34 (credible intervals: 1.02;1.76). The same trends were observed for OHCAs in out-of-office hours (4pm-08am) with a significant OR of 1.43 (credible intervals: 1.09;1.89). Local clusters with low rate of BLS course participation and bystander CPR were identified.

Conclusion

This study found a positive effect of mass education in BLS on bystander CPR rates. Even a 5% increase in BLS course participation at municipal level significantly increased the likelihood of bystander CPR. The effect was even more profound in out-of-office hours with an increase in bystander CPR rate at OHCA.

Effective methods to enhance medical students' cardioversion and transcutaneous cardiac pacing skills retention - a prospective controlled study

BACKGROUND

Guideline-based therapy of cardiac arrhythmias is important for many physicians from the beginning of their training. Practical training of the required skills to treat cardiac arrhythmias is useful for acquiring these skills but does not seem sufficient for skill retention. The aim of this study was to compare different retention methods for skills required to treat cardiac arrhythmias with respect to the performance of these skills in an assessment.

METHODS

Seventy-one final-year medical students participated in a newly designed workshop to train synchronized cardioversion (SC) and transcutaneous cardiac pacing (TCP) skills in 2020. All participants completed an objective structured clinical examination (OSCE 1) one week after the training. Afterwards, the participants were stratified and randomized into three groups. Nine weeks later, one group received a standard operating procedure (SOP) for the skills, one group participated in a second workshop (SW), and one group received no further intervention (control). Ten weeks after the first training, all groups participated in OSCE 2.

RESULTS

The average score of all students in OSCE 1 was 15.6 ± 0.8 points with no significant differences between the three groups. Students in the control group reached a significantly (p < 0.001) lower score in OSCE 2 (-2.0 points, CI: [-2.9;-1.1]) than in OSCE 1. Students in the SOP-group achieved on average the same result in OSCE 2 as in OSCE 1 (0 points, CI: [-0.63;+0.63]). Students who completed a second skills training (SW-group) scored not significantly higher in OSCE 2 compared to OSCE 1 (+0.4 points, CI: [-0.29;+1.12]). The OSCE 2 scores in groups SOP and SW were neither significantly different nor statistically equivalent.

CONCLUSIONS

Partial loss of SC and TCP skills acquired in a workshop can be prevented after 10 weeks by reading an SOP as well as by a second workshop one week before the second assessment. Refreshing practical skills with an SOP could provide an effective and inexpensive method for skills retention compared to repeating a training. Further studies need to show whether this effect also exists for other skills and how frequently an SOP should be re-read for appropriate long-term retention of complex skills.

The effective group size for teaching cardiopulmonary resuscitation skills - A randomized controlled simulation trial

AIM OF THE STUDY

The ideal group size for effective teaching of cardiopulmonary resuscitation is currently under debate. The upper limit is reached when instructors are unable to correct participants' errors during skills practice. This simulation study aimed to define this limit during cardiopulmonary resuscitation teaching.

METHODS

Medical students acting as simulated Basic Life Support course participants were instructed to make three different pre-defined Basic Life Support quality errors (e.g., chest compression too fast) in 7 min. Basic Life Support instructors were randomized to groups of 3-10 participants. Instructors were asked to observe the Basic Life Support skills and to correct performance errors. Primary outcome was the maximum group size at which the percentage of correctly identified participants' errors drops below 80%.

RESULTS

Sixty-four instructors participated, eight for each group size. Their average age was 41 ± 9 years and 33% were female, with a median [25th percentile; 75th percentile] teaching experience of 6 [2;11] years. Instructors had taught 3 [1;5] cardiopulmonary resuscitation courses in the year before the study. A logistic binominal regression model showed that the predicted mean percentage of correctly identified participants' errors dropped below 80% for group sizes larger than six.

CONCLUSION

This randomized controlled simulation trial reveals decreased ability of instructors to detect Basic Life Support performance errors with increased group size. The maximum group size enabling Basic Life Support instructors to correct more than 80% of errors is six. We therefore recommend a maximum instructor-to-participant ratio of 1:6 for cardiopulmonary resuscitation courses.

Guess it (SVUAL): An app designed to help nursing students acquire and retain knowledge about basic and advanced life support techniques

To design an app that helps nursing students to acquire and retain knowledge of Basic and Advanced Life Support techniques, as well as analyze the students' gamification experience. The study had two phases: 1) App design and development and 2) experimental study. A total of 184 students participated, with 92 in the experimental group and 92 in the control group. The instruments used were the Guess it (SVUAL) app, a test on knowledge and the Gameful Experience Scale. The app was deemed to have a suitable level of content and user-friendliness of 97%. The experimental group obtained a higher average score on the knowledge test than the control group (U = 2835.500; Z = -3.968; p < 0.05). On the re-test, the experimental group also obtained a higher average score than the control group. As for the experience within the game, all the dimensions scored higher than average, except the absence of negative effects dimension, which indicates that the app had very few negative consequences on the participants. The developed app has proven to have a good level of content and to be user-friendly, improving knowledge levels and retention of information in nursing students.

The Copenhagen Tool a research tool for evaluation of basic life support educational interventions

INTRODUCTION

Over the past decades, major changes have been made in basic life support (BLS) guidelines and manikin technology. The aim of this study was to develop a BLS evaluation tool based on international expert consensus and contemporary validation to enable more valid comparison of research on BLS educational interventions.

METHODS

A modern method for collecting validation evidence based on Messick's framework was used. The framework consists of five domains of evidence: content, response process, internal structure, relations with other variables, and consequences. The research tool was developed by collecting content evidence based on international consensus from an expert panel; a modified Delphi process decided items essential for the tool. Agreement was defined as identical ratings by 70% of the experts.

RESULTS

The expert panel established consensus on a three-levelled score depending on expected response level: laypersons, first responders, and health care personnel. Three Delphi rounds with 13 experts resulted in 16 "essential" items for laypersons, 21 for first responders, and 22 for health care personnel. This, together with a checklist for planning and reporting educational interventional studies within BLS, serves as an example to be used for researchers.

CONCLUSIONS

An expert panel agreed on a three-levelled score to assess BLS skills and the included items. Expert panel consensus concluded that the tool serves its purpose and can act to guide improved research comparison on BLS educational interventions.

Baseline Cardiopulmonary Resuscitation Skill Performance of Nursing Students Is Improved After One Resuscitation Quality Improvement Skill Refresher

This article reports the results of baseline cardiopulmonary resuscitation (CPR) skills performance measurements from 467 nursing students. All participants had completed a CPR course. Baseline measurements were compared to performance after one 10-minute refresher training session on the Resuscitation Quality Improvement system. Significant improvements were made after the computer- and practice-based refresher. Findings suggest that staff developers should evaluate the use of audio and visual feedback devices to improve the quality of CPR provided by clinical staff.

Evaluation of a Multimodal Resuscitation Program and Comparison of Mouth-to-Mouth and Bag-Mask Ventilation by Relatives of Children With Chronic Diseases

OBJECTIVES

Children with chronic critical illness are at higher risk for cardiopulmonary arrests. Before chronically ill children are discharged from hospital, family members receive training in basic life support at many institutions. We evaluated whether a multimodal training program is able to teach adherence to current resuscitation guidelines and whether laypersons can be trained to perform both bag-mask ventilation and mouth-to-mouth ventilation equally effective in infants.

DESIGN

Prospective observational study.

SETTING

Pediatric critical care unit of a tertiary referral center.

SUBJECTS

Relatives of children with chronic illness prior to discharge from hospital.

INTERVENTIONS

Multimodal emergency and cardiopulmonary resuscitation training program.

MEASUREMENTS AND MAIN RESULTS

Following participation in our cardiopulmonary resuscitation training program 56 participants performed 112 simulated cardiopulmonary resuscitations (56 with mouth-to-mouth ventilation, 56 with bag-mask ventilation). Nearly all participants checked for consciousness and breathing. Shouting for help and activation of the emergency response system was only performed in half of the cases. There was almost full adherence to the resuscitation guidelines regarding number of chest compressions, chest compression rate, compression depth, full chest recoil, and duration of interruption of chest compression for rescue breaths. The comparison of mouth-to-mouth ventilation and bag-mask ventilation revealed no significant differences regarding the rate of successful ventilation (mouth-to-mouth ventilation: 77.1% ± 39.6%, bag-mask ventilation: 80.4% ± 38.0%; p = 0.39) and the cardiopulmonary resuscitation performance.

CONCLUSIONS

A standardized multimodal cardiopulmonary resuscitation training program for family members of chronically ill children is effective to teach good cardiopulmonary resuscitation performance and adherence to resuscitation guidelines. Laypersons could be successfully trained to equally perform mouth-to-mouth and bag-mask ventilation technique.

Effectiveness of web-based education in addition to basic life support learning activities: A cluster randomised controlled trial

BACKGROUND

Effective education in basic life support (BLS) may improve the early initiation of high-quality cardiopulmonary resuscitation and automated external defibrillation (CPR-AED).

AIM

To compare the learning outcome in terms of practical skills and knowledge of BLS after participating in learning activities related to BLS, with and without web-based education in cardiovascular diseases (CVD).

METHODS

Laymen (n = 2,623) were cluster randomised to either BLS education or to web-based education in CVD before BLS training. The participants were assessed by a questionnaire for theoretical knowledge and then by a simulated scenario for practical skills. The total score for practical skills in BLS six months after training was the primary outcome. The total score for practical skills directly after training, separate variables and self-assessed knowledge, confidence and willingness, directly and six months after training, were the secondary outcomes.

RESULTS

BLS with web-based education was more effective than BLS without web-based education and obtained a statistically significant higher total score for practical skills at six months (mean 58.8, SD 5.0 vs mean 58.0, SD 5.0; p = 0.03) and directly after training (mean 59.6, SD 4.8 vs mean 58.7, SD 4.9; p = 0.004).

CONCLUSION

A web-based education in CVD in addition to BLS training enhanced the learning outcome with a statistically significant higher total score for performed practical skills in BLS as compared to BLS training alone. However, in terms of the outcomes, the differences were minor, and the clinical relevance of our findings has a limited practical impact.
