Cardiopulmonary resuscitation in low-resource settings: a statement by the International Liaison Committee on Resuscitation, supported by the AFEM, EUSEM, IFEM, and IFRC

International facets of the 'chain of survival' for out-of-hospital and in-hospital cardiac arrest - A scoping review

Background

The "chain of survival" was first systematically addressed in 1991, and its sequence still forms the cornerstone of current resuscitation guidelines. The term "chain of survival" is widely used around the world in literature, education, and awareness campaigns, but growing heterogeneity in the components of the chain has led to confusion. It is unclear which of these emerging chains is most suitable, or if adaptations are needed in particular contexts to depict key actions of resuscitation in the 21st century. This scoping review provides an overview of the variety of chains of survival described.

Objectives

To identify published facets of the chain of survival, to assess views and strategies about adapting the chain, and to identify reports on how the chain of survival affects teaching, implementation, or patient outcomes.

Methods eligibility criteria and sources of evidence

A scoping review as part of the continuous evidence evaluation process of the International Liaison Committee on Resuscitation (ILCOR) was conducted. MEDLINE(R) ALL (Ovid), Embase (Ovid), APA PsycINFO (Ovid), CINAHL (Ebscohost), ERIC (Ebscohost), Web of Science (Clarivate), Scopus (Elsevier), and Cochrane Library (Wiley Online) were searched. All publications in all languages describing chains of survival were eligible, without time restrictions. Due to the heterogeneity and publication types of the relevant studies, we did not pursue a systematic review or meta-analysis.

Results

A primary search yielded 1713 studies and after screening we included 43 publications. Modified versions of the chain of survival for specific contexts were found (e.g., in-hospital cardiac arrest or paediatric resuscitation). There were also numerous versions with minor adaptations of the existing chain. Three publications suggested an impact of the use of the chain of survival on patient outcomes. No educational or implementation outcomes were reported.

Conclusion

There is a vast heterogeneity of chain of survival concepts published. Future research is warranted, especially into the concept's importance concerning educational, implementation, and clinical outcomes.

"1990 Suwa Seriya" the national pre-hospital care ambulance service of Sri Lanka; a narrative review describing the EMS system with special emphasis on Out of Hospital Cardiac Arrest (OHCA) in Sri Lanka

Background

Sri Lanka is a leading nation in healthcare provision in the South Asia. Notably, it recorded amongst the lowest maternal and neonatal mortality rates in the region. However a significant deficit in improving all-cause mortality rates was the absence of a cohesive system of pre-hospital care.

Method

This narrative review delves into the evolution of Sri Lanka's Emergency Medical Services (EMS) system over the past decade. It examines the historical context, challenges encountered, and the transformative role of the "1990 Suwa Seriya" ambulance service on all causes of morbidity and mortality rates including out-of-hospital cardiac arrest (OHCA).

Results

The review elucidates the path from no organised pre-hospital system in 2015 to a comprehensive free to public, pre-hospital care emergency ambulance service that effectively serves 22 million people nationa-wide in 6 short years. Collaborations with emergency medicine, novel approaches to training and credentialing, as well as evolving research initiatives illustrate an approach to be emulated in countries with emerging pre-hospital systems. 1990 Suwa Seriya's response during the COVID-19 pandemic and its implications on public perception are discussed in conjunction with efforts to limit morbidity and mortality from OHCA.

Conclusion

In conclusion, the article underscores 1990 Suwa Seriya's dedication to continuous improvement and its potential as a model for bolstering emergency healthcare. By addressing challenges, fostering collaborations, and adapting to crises like the COVID-19 pandemic, 1990 Suwa Seriya exemplifies a pathway towards elevating pre-hospital care standards in lower-middle-income countries (LMICs).

Self-evaluation of ILCORs ten steps to improve around in-hospital cardiac arrests among Swedish hospitals

Objectives

Recently, ILCOR unveiled the ground-breaking global initiative "Ten Steps Toward Improving In-Hospital Cardiac Arrest" (IHCA).

Aim

To generate a baseline of how well the ten steps currently function in Sweden, in order to better target educational interventions.

Material and methods

A survey was created using an online form application (Google Forms) and sent to CPR coordinators and physicians in charge of CPR at all 74 Swedish hospitals participating in the Swedish Registry for Cardiopulmonary Resuscitation (SRCR). Hospitals were asked to self-evaluate their functionality on each step on a ten-point scale ranging from 1 "Not present or not functioning at all" to 10 "Very well-functioning". Data regarding number of IHCA and their survival during 2018-2022 was gathered from the SRCR.

Results

A total of 34 out of 74 (46%) Swedish hospitals participated in the survey, collectively representing 59% (7,113 out of 12,070) of IHCA cases in SRCR. The responding hospitals were satisfied with the functionality of just over half of the steps currently (median 60%, range 30-90%). The steps with the highest proportion of satisfied hospitals were found for step 6-rapid response systems (85%) and 7-guideline-based resuscitation (94%), while the steps with lowest proportion of satisfied hospitals were found for step 4-goals of treatment (32%) and step 9-person centred culture (18%). About half of participating hospitals expressed intent to prioritise upcoming years' work on step 1- infrastructure, step 3- effective education and step 5- stop preventable IHCA.

Conclusion

The conclusion is that most hospitals judge themselves to be well-functioning on many of the ten steps, but steps involving effective education might need attention, as well as the tolerance for presence of preventable IHCA being low.

Evaluation of resuscitation systems in the Democratic Republic of Congo: A narrative review

Introduction

Limited data exists regarding cardiovascular diseases (CVDs) and related emergencies such as out-of-hospital cardiac arrest (OHCA) in low- and middle-income countries (LMICs). The recent burden of disease report indicates a rising prevalence of CVDs in these settings like the Democratic Republic of Congo (DRC), likely associated with acute complications. Achieving improved outcomes necessitates resilient healthcare systems, including adequate emergency care and resuscitation systems. This study aims to characterize the current state of resuscitation systems in the DRC, contributing to the discourse on the burden of CVDs in LMICs and advocating for context-appropriate interventions to develop and reinforce these systems.

Methods

A narrative review utilizing the modified survival framework of the Global Resuscitation Alliance was conducted. It encompassed the country's CVD epidemiological data, healthcare components, and emergency care system.

Results

Analysis of limited available data revealed an underdeveloped and inadequately resourced healthcare system in the country, particularly its early-stage emergency care component. While specific data on out-of-hospital cardiac arrests were lacking, crucial components of the survival chain necessary for improved post-arrest outcomes were found to be largely deficient. Community-based first aid knowledge and practice were inadequate, the availability of automated external defibrillators (AEDs) and integrated ambulance services were either absent or insufficiently developed, and facility-based resuscitation capacity was predominantly in its infancy. Nonetheless, optimism is warranted due to recent government decisions to increase total health expenditure and progressively implement Universal Health Coverage.

Conclusion

Resuscitation systems in the DRC are largely non-existent, reflecting the country's underdeveloped healthcare system, particularly in emergency care. Urgent action is needed to develop and reinforce context-appropriate resuscitation systems to address the growing burden of CVD-related emergencies in LMICs.

Top 5 barriers in cardiac arrest research as perceived by international early career researchers - A consensus study

Aim of the study

Cardiac arrest research has not received as much scientific attention as research on other topics. Here, we aimed to identify cardiac arrest research barriers from the perspective of an international group of early career researchers.

Methods

Attendees of the 2022 international masterclass on cardiac arrest registry research accompanied the Global Out-of-Hospital Cardiac Arrest Registry collaborative meeting in Utstein, Norway, and used an adapted hybrid nominal group technique to obtain a diverse and comprehensive perspective. Barriers were identified using a web-based questionnaire and discussed and ranked during an in-person follow-up meeting. After each response was discussed and clarified, barriers were categorized and ranked over two rounds. Each participant scored these from 1 (least significant) to 5 (most significant).

Results

Nine participants generated 36 responses, forming seven overall categories of cardiac arrest research barriers. "Allocated research time" was ranked first in both rounds. "Scientific environment", including appropriate mentorship and support systems, ranked second in the final ranking. "Resources", including funding and infrastructure, ranked third. "Access to and availability of cardiac arrest research data" was the fourth-ranked barrier. This included data from the cardiac arrest registries, medical devices, and clinical studies. Finally, "uniqueness" was the fifth-ranked barrier. This included ethical issues, patient recruitment challenges, and unique characteristics of cardiac arrest.

Conclusion

By identifying cardiac arrest research barriers and suggesting solutions, this study may act as a tool for stakeholders to focus on helping early career researchers overcome these barriers, thus paving the road for future research.

A resuscitation systems analysis for South Africa: A narrative review

With a growing incidence in cardiovascular diseases in Africa, including South Africa, and with it a greater incidence of out-of-hospital cardiac arrest (OHCA) there is a need to understand the readiness of these emergency care systems to support a response. Yet, OHCA is expensive and requires comprehensive development across an entire chain of survival in order to gain any benefit in mortality or morbidity. In this narrative review, we provide a resuscitation systems analysis using the Global Resuscitation Alliance's Frame of Survival. We provide evidence or commentary on the elements of the outer frame and inner frame, and make an assessment of the South African system's readiness to support OHCA care, and provide suggestions for priority areas that need to be developed. The South African resuscitation system demonstrates reasonable readiness to respond to OHCA but is characterised by considerable variation and fragmentation. Given the cost ineffectiveness of many interventions and the anticipated rise in OHCA incidence, there is a pressing need for context-specific strategies in South Africa. These strategies should focus on enhancing both outcomes and resource efficiency, while respecting community ethics and sociocultural dynamics.

Pakistan's Emergency Medical Services (EMS) system & out-of-hospital-cardiac-arrest (OHCA): A narrative review of an EMS system of a low middle income country in context of OHCA

Pakistan's Emergency Medical Services (EMS) are a critical component of its healthcare system, providing pre-hospital emergency care across a nation with over 220 million people. This article explores the evolutionary journey of Pakistan's EMS, highlighting both the challenges it faces and the strides it has made, with a specific emphasis on patients experiencing out-of-hospital cardiac arrest (OHCA). To extract relevant information, we searched MEDLINE & Embase data bases using MeSH terms "Emergency Medical Services" OR "EMS" AND "Out-of-Hospital-Cardiac-Arrest" OR "OHCA" AND "Pakistan". In addition, we also retrieved information from the EMS leadership in Pakistan through e-mails. We delve into the significance of key performance indicators for OHCA, advocate for the establishment of OHCA registries to improve patient outcomes, address regional disparities in pre-hospital care, and acknowledge the gradual progress of the EMS system.

Survival After Out-of-Hospital Cardiac Arrest Before and After Legislation for Bystander CPR

Importance

The lack of evidence-based implementation strategies is a major contributor to increasing mortality due to out-of-hospital cardiac arrest (OHCA) in developing countries with limited resources.

Objective

To evaluate whether the implementation of legislation is associated with increased bystander cardiopulmonary resuscitation (CPR) and automated external defibrillator (AED) use and improved clinical outcomes for patients experiencing OHCA and to provide policy implications for low-income and middle-income settings.

Design, Setting, and Participants

This observational cohort study analyzed a prospective city registry of patients with bystander-witnessed OHCA between January 1, 2010, and December 31, 2022. The Emergency Medical Aid Act was implemented in Shenzhen, China, on October 1, 2018. An interrupted time-series analysis was used to assess changes in outcomes before and after the law. Data analysis was performed from May to October 2023.

Exposure

The Emergency Medical Aid Act stipulated the use of AEDs and CPR training for the public and provided clear legal guidance for OHCA rescuing.

Main Outcomes and Measures

The primary outcomes were rates of bystander-initiated CPR and use of AEDs. Secondary outcomes were rates of prehospital return of spontaneous circulation (ROSC), survival to arrival at the hospital, and survival at discharge.

Results

A total of 13 751 patients with OHCA (median [IQR] age, 59 [43-76] years; 10 011 men [72.83%]) were included, with 7858 OHCAs occurring during the prelegislation period (January 1, 2010, to September 30, 2018) and 5893 OHCAs occurring during the postlegislation period (October 1, 2018, to December 31, 2022). The rates of bystander-initiated CPR (320 patients [4.10%] vs 1103 patients [18.73%]) and AED use (214 patients [4.12%] vs 182 patients [5.29%]) increased significantly after legislation implementation vs rates before the legislation. Rates of prehospital ROSC (72 patients [0.92%] vs 425 patients [7.21%]), survival to arrival at the hospital (68 patients [0.87%] vs 321 patients [5.45%]), and survival at discharge (44 patients [0.56%] vs 165 patients [2.80%]) were significantly increased during the postlegislation period. Interrupted time-series models demonstrated a significant slope change in the rates of all outcomes.

Conclusions and Relevance

These findings suggest that implementation of the Emergency Medical Aid Act in China was associated with increased rates of CPR and public AED use and improved survival of patients with OHCA. The use of a systemwide approach to enact resuscitation initiatives and provide legal support may reduce the burden of OHCA in low-income and middle-income settings.

Challenges & barriers for real-time integration of drones in emergency cardiac care: Lessons from the United States, Sweden, & Canada

Importance

Out-of-hospital cardiac arrest (OHCA) is a leading cause of morbidity and mortality in the US and Europe (∼600,000 incident events annually) and around the world (∼3.8 million). With every minute that passes without cardiopulmonary resuscitation or defibrillation, the probability of survival decreases by 10%. Preliminary studies suggest that uncrewed aircraft systems, also known as drones, can deliver automated external defibrillators (AEDs) to OHCA victims faster than ground transport and potentially save lives.

Objective

To date, the United States (US), Sweden, and Canada have made significant contributions to the knowledge base regarding AED-equipped drones. The purpose of this Special Communication is to explore the challenges and facilitators impacting the progress of AED-equipped drone integration into emergency medicine research and applications in the US, Sweden, and Canada. We also explore opportunities to propel this innovative and important research forward.

Evidence review

In this narrative review, we summarize the AED-drone research to date from the US, Sweden, and Canada, including the first drone-assisted delivery of an AED to an OHCA. Further, we compare the research environment, emergency medical systems, and aviation regulatory environment in each country as they apply to OHCA, AEDs, and drones. Finally, we provide recommendations for advancing research and implementation of AED-drone technology into emergency care.

Findings

The rates that drone technologies have been integrated into both research and real-life emergency care in each country varies considerably. Based on current research, there is significant potential in incorporating AED-equipped drones into the chain of survival for OHCA emergency response. Comparing the different environments and systems in each country revealed ways that each can serve as a facilitator or barrier to future AED-drone research.

Conclusions and relevance

The US, Sweden, and Canada each offers different challenges and opportunities in this field of research. Together, the international community can learn from one another to optimize integration of AED-equipped drones into emergency systems of care.

The Young European Resuscitation Council Resuscitation Science Masterclass - Concept and implementation

Nurturing the development of the next generation of resuscitation scientists is essential for creating a vibrant and enabled community equipped with the necessary knowledge, attitudes, and skills to transform resuscitation practice and improve outcomes. In this concept paper we will describe the development and implementation of the first Young European Resuscitation Council Resuscitation Science Masterclass. The masterclass aims to connect, inspire, and support the growth of the next generation of resuscitation scientists through education, networking, and joint scientific work. The masterclass provides 20 international, multi-professional early career resuscitation scientists with the opportunity to expand their knowledge and network as well as conduct joint scientific work over the course of one year. This is achieved by interactive webinars, innovative online workshops, engaging online journal clubs as well as an educational in-person event to conclude the masterclass. The Young European Resuscitation Council Resuscitation Science Masterclass aims to strengthen the global resuscitation community and next generation of resuscitation scientists by facilitating opportunities of broader international initiatives and collaboration for early career resuscitation scientists, potentially leading to accelerated recruitment of future resuscitation leaders. Ultimately, this masterclass may enable early career researchers to produce high impact research that can shape the future of resuscitation science and improve cardiac arrest patient care globally.

Redesigning Prehospital Care: Fiji's Response to the COVID-19 Pandemic

The benefits of emergency care systems in low- and middle-income countries are well-described. Passed in the wake of the coronavirus disease 2019 (COVID-19) pandemic, the World Health Assembly (WHA) Resolution 76.2 emphasizes the importance of communication, transportation and referral mechanisms, and the linkages between communities, primary care, and hospital care. Literature describing prehospital care and ambulance system development is scarce, with little data on the effectiveness and cost effectiveness of different options. Prehospital care systems in Pacific Island countries are under-developed. In Fiji, out-of-hospital care is fragmented with an uncoordinated patchwork of ambulance providers. There is no scope of practice or training requirement for providers and no patient care records. There are no data relating to demand, access, and utilization of ambulance services.In response to a surge of COVID-19 cases in 2021, the Fiji government created a Prehospital Emergency Care Coordination Center (PHECCC) in the capital Suva, which was operational from July-October 2021. Access was via a toll-free number, whereby the public could receive a medical consultation followed by phone advice or dispatch of an ambulance for a home assessment, followed by transportation to hospital, if required. The PHECCC also provided coordination of inter-facility transport and retrieval of the critically ill.The system that was created met many of the prehospital care standards set by emergency care leaders in the region and created the first dataset relating to ambulance demand and utilization. This is the first article to document prehospital system development in the Pacific region.

Comparative Analysis of the Impact of Training through Simulation Using the Crisis Resource Management Tool for Primary Care Professionals

This was a prospective observational study based on clinical simulation courses taught in 2017 at the IDEhA Simulation Center of Alcorcón Foundation University Hospital. Two courses in metabolic emergencies (MEs) and respiratory emergencies (REs) were offered to primary care physicians all over Spain. The main objective was to teach nontechnical skills (crisis resource management). Using a modified five-level Kirkpatrick-Phillips education evaluation model, level I (reaction, K1), level II (learning, K2) and level III (behavioral change, K3) changes were evaluated through surveys at the end of the courses and one year later. Thirty courses were held (15 ME courses and 15 RE courses) with 283 primary care physicians. The overall satisfaction (K1) was high: ME courses, 9.5/10; RE courses, 9.6/10. More than 80% of the participants rated the organization, resources, content, debriefing and scenarios as excellent, with no significant differences between the two courses. After one year (156 responses), the respondents for both courses reported that they would repeat the training annually (K2), encourage debriefing with colleagues (K3) and have modified some aspects of their workplace (K3), citing improvements in procedures and in the organization of the health team as the most important. After the ME course, few participants, i.e., 5 (6%), reported providing improved care to patients; after the RE course, 15 (19%) participants reported providing improved care; the difference between groups was significant (p < 0.05). Compared with the ME course, the RE course imparted greater knowledge about patient safety (K2) (38 (49%) vs. 24 (31%) (p < 0.05)) and more useful tools for daily clinical practice (K3) (67% vs. 56.4%) and resulted in participants paying more attention to personal performance and to colleagues when working as a team (K2) (64% vs. 50%). Clinical simulation courses are highly valued and potentially effective for training primary care physicians in patient safety and CRM tools. Future studies with objective measures of long-term impact, behavior in the workplace (K3) and benefits to patients (K4) are needed. Based on the results of our study, the areas that are important are those aimed at improving procedures and the organization of health teams.

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.

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.

Clinical Trials and Therapeutic Approaches for Healthcare Challenges in Pakistan

Pakistan faces tremendous challenges in providing healthcare due to a lack of consistent policymaking, increasing expenditure and exponential growth in population since its inception in 1947. These challenges are not just driven by politics, policy and allocation of resources but also by healthcare, environment and characteristics of the population biology. Clinical trials provide the best way to find population-specific, cost-effective treatments that do not merely mimic those used in wealthier nations. This article analyzes all clinical studies conducted with at least one site in Pakistan listed on ClinicalTrials.gov, combined with a short overview that considers new therapeutic approaches that can be investigated in future clinical trials. Therapies using repurposed medicines are of particular interest as they use affordable drugs that are already widely available.
