Impact of community-based interventions on out-of-hospital cardiac arrest outcomes: a systematic review and meta-analysis

Health systems developments and predictors of bystander CPR in Ireland

Aims

To explore predictors of bystander CPR (i.e. any CPR performed prior to EMS arrival) in Ireland over the period 2012-2020. To examine the relationship between bystander CPR and key health system developments during this period.

Methods

National level out-of-hospital cardiac arrest (OHCA) registry data relating to unwitnessed, and bystander witnessed OHCA were interrogated. Logistic regression models were built, then refined by fitting predictors, performing stepwise variable selection and by adding pairwise interactions that improved fit. Missing data sensitivity analyses were conducted using multiple imputation.

Results

The data included 18,177 OHCA resuscitation attempts of whom 77% had bystander CPR. The final model included ten variables. Four variables (aetiology, incident location, time of day, and who witnessed collapse) were involved in interactions. The COVID-19 period was associated with reduced adjusted odds of bystander CPR (OR 0.77, 95% CI 0.65, 0.92), as were increasing age in years (OR 0.992, 95% CI 0.989, 0.994) and urban location (OR 0.52, 95% CI 0.47, 0.57). Increasing year over time (OR 1.23, 95% CI 1.16, 1.29), and an increased call response interval in minutes (OR 1.017, 95% CI 1.012, 1.022) were associated with increased adjusted odds of bystander CPR.

Conclusions

Bystander CPR increased over the study period, and it is likely that health system developments contributed to the yearly increases observed. However, COVID-19 appeared to disrupt this positive trend. Urban OHCA location was associated with markedly decreased odds of bystander CPR compared to rural location. Given its importance bystander CPR in urban areas should be an immediate target for intervention.

Challenges and best practices of dispatcher-assisted cardiopulmonary resuscitation: A scoping review protocol

Introduction

Improved survival from out-of-hospital cardiac arrest with good neurological outcome was observed in association with dispatcher-assisted cardiopulmonary resuscitation, increasing the number of bystander-initiated resuscitations and minimizing the no-flow time in the first minutes of cardiac arrest.

Objective

The objective of this scoping review is to map and summarise the existing literature on dispatcher-assisted cardiopulmonary resuscitation, focusing on reported experiences, challenges, and best practices, highlighting strategies that could improve the provision of cardiopulmonary resuscitation instructions to bystanders during out-of-hospital cardiac arrest.

Inclusion criteria

Studies related to dispatcher-assisted cardiopulmonary resuscitation, involving human subjects, with an English abstract. The concept of interest is focused on the methods of provision of dispatcher-assisted cardiopulmonary resuscitation analysing specific experiences of implementation, challenges, and best practices, and can be generalized to any country; cultural factors, geographic features, and specific racial or gender-based differences will be analysed and discussed.

Methods

Four databases (PubMed, Embase, Cumulative Index to Nursing & Allied Health Literature, and the Cochrane Library) will be searched for studies published from 2018 to 2023. All study designs, including experimental and observational studies, will be assessed for inclusion. Titles and abstracts of identified citations will be screened for inclusion; subsequently, full texts of potentially relevant sources will be assessed for inclusion by two reviewers. Any disagreements between the reviewers will be resolved through discussion. Relevant grey literature (conference proceedings, government documents, and theses) will be analysed and included. Data will be extracted in a standardized form, following Joanna Briggs Institute recommendations. Results will be synthesized and reported using a narrative approach, categorising findings into themes related to the effectiveness of dispatcher-assisted cardiopulmonary resuscitation, challenges, and best practices.

Impact of intravenous accessibility and prehospital epinephrine use on survival outcomes of adult nontraumatic out-of-hospital cardiac arrest patients

BACKGROUND

This study compared out-of-hospital cardiac arrest (OHCA) patient outcomes based on intravenous (IV) access and prehospital epinephrine use.

METHODS

A retrospective study in Ulsan, South Korea, from January 2017 to December 2022, analyzed adult nontraumatic OHCA cases. Patients were grouped: Group 1 (no IV attempts), Group 2 (failed IV access), Group 3 (successful IV access without epinephrine), and Group 4 (successful IV access with epinephrine), with comparisons using logistic regression analysis.

RESULTS

Among 2,656 patients, Group 4 had significantly lower survival to hospital discharge (adjusted OR 0.520, 95% CI 0.346-0.782, p = 0.002) and favorable neurological outcomes (adjusted OR 0.292, 95% CI 0.140-0.611, p = 0.001) than Group 1. Groups 2 and 3 showed insignificant survival to hospital discharge (adjusted OR 0.814, 95% CI 0.566-1.171, p = 0.268) and (adjusted OR 1.069, 95% CI 0.810-1.412, p = 0.636) and favorable neurological outcomes (adjusted OR 0.585, 95% CI 0.299-1.144, p = 0.117) and (adjusted OR 1.075, 95% CI 0.689-1.677, p = 0.751). In the shockable rhythm group, Group 3 had better survival to hospital discharge (adjusted OR 1.700, 95% CI 1.044-2.770, p = 0.033).

CONCLUSIONS

Successful IV access with epinephrine showed worse outcomes in both rhythm groups than no IV attempts. Outcomes for failed IV and successful IV access without epinephrine were inconclusive. Importantly, successful IV access without epinephrine showed favorable survival to hospital discharge in the shockable rhythm group, warranting further research into IV access for fluid resuscitation in shockable rhythm OHCA patients.

Trauma systems in high socioeconomic index countries in 2050

Considerable political, structural, environmental and epidemiological change will affect high socioeconomic index (SDI) countries over the next 25 years. These changes will impact healthcare provision and consequently trauma systems. This review attempts to anticipate the potential impact on trauma systems and how they could adapt to meet the changing priorities. The first section describes possible epidemiological trajectories. A second section exposes existing governance and funding challenges, how these can be met, and the need to incorporate data and information science into a learning and adaptive trauma system. The last section suggests an international harmonization of trauma education to improve care standards, optimize immediate and long-term patient needs and enhance disaster preparedness and crisis resilience. By demonstrating their capacity for adaptation, trauma systems can play a leading role in the transformation of care systems to tackle future health challenges.

Wolf creek XVII part 4: Amplifying lay-rescuer response

Introduction

Amplifying lay-rescuer response is a key priority to increase survival from out-of-hospital cardiac arrest (OHCA). We describe the current state of lay-rescuer response, how we envision the future, and the gaps, barriers, and research priorities that will amplify response to OHCA.

Methods

'Amplifying Lay-Rescuer Response' was one of six focus topics for the Wolf Creek XVII Conference held on June 14-17, 2023, in Ann Arbor, Michigan, USA. Conference invitees included international thought leaders and scientists in the field of cardiac arrest resuscitation from academia and industry. Participants submitted via online survey knowledge gaps, barriers to translation and research priorities for each focus topic. Expert panels used the survey results and their own perspectives and insights to create and present a preliminary unranked list for each category that was debated, revised and ranked by all attendees to identify the top 5 for each category.

Results

The top five knowledge gaps as ranked by the panel, reflected a recognition of the need to better understand the psycho-social aspects of lay response. The top five barriers to translation reflected issues at the individual, community, societal, structural, and governmental levels. The top five research priorities were focused on understanding the social/psychological and emotional barriers to action, finding the most effective/cost-effective strategies to educate lay persons and implement community life-saving interventions, evaluation of new technological solutions and how to enhance the role of dispatch working with lay-rescuers.

Conclusion

Future research in lay rescuer response should incorporate technology innovations, understand the "humanity" of the situation, leverage implementation science and systems thinking to save lives. This will require the field of resuscitation to engage with scholars outside our traditional ranks and to be open to new ways of thinking about old problems.

Emergency Scenario-Based Training Curriculum Development: Enhancement of Caregivers for the Elderly' Emergency Assistance Competency in a Rural Thai Community

Background

Caregivers for the elderly are a critical component of the health care system, especially in rural communities. They play a crucial role, assisting older people in confronting emergency illnesses.

Objective

The study describes the process of developing an emergency scenario-based training curriculum (ESBTC) for caregivers of the elderly, focusing on geriatric life-threatening surveillance and emergency assistance (GLTSEA) in rural communities.

Methods

The descriptive qualitative research utilized for developing the ESBTC followed Karn's six steps of curriculum development: (1) needs assessment, (2) targeted needs assessment, (3) goals and objectives, (4) educational strategies, (5) implementation, and (6) evaluation and feedback. The research sample comprised community representatives engaged in providing care during emergency illnesses, emergency experts, and health care providers. A group discussion and focus group were conducted along with semi-structured interviews. The data were analyzed by content analysis following Creswell's six steps.

Results

The results revealed problems and needs related to the care and management of emergency illnesses in rural communities. Five main themes emerged, including insufficient knowledge, difficulties in communication, mindfulness and self-confidence, Unable to assess the initial symptoms, and a need for skills development. In the development step, the curriculum focused on skill development and continued follow-up to ensure necessary skills, such as providing basic life support, using automated external defibrillators, through training scenarios. In the evaluation step, the participants indicated that their emergency assistance skills had improved. The six main themes that emerged regarding the training continuity, courses, and competencies needed to support the emergency system for caregivers were benefits and value, competence enhancements, upstreaming confidence, sustainable development, challenges in curriculum development, and effective strategies.

Conclusions

The ESBTC combines community-based and realistic scenarios, involving the participation of community stakeholders. It is crucial to gather community feedback and needs assessments to formulate potential strategies as part of the curriculum.

OHCA in Bosnia and Herzegovina: Before and During the COVID-19 Pandemic

Background

Out-of-hospital cardiac arrest (OHCA) refers to the cessation of mechanical cardiac activity outside healthcare facilities which requires prompt intervention and intensive resuscitative efforts. The COVID-19 pandemic has caused significant disruptions to OHCA systems-of-care, adversely affecting every component of the chain of survival.

Objective

The objective of this study was to examine the potential impacts of the COVID-19 pandemic on OHCA events, to draw comparisons between the period before and during the COVID-19 pandemic.

Methods

This cross-sectional study encompassed data pertaining to all OHCA incidents attended to by the Emergency Medical Service of Canton Sarajevo, covering the period from January 2017 to December 2022, before and during the COVID-19 pandemic.

Results

During observed period, a total of 1418 [796 (56.1%) before and 622 (43.9%) during COVID-19 pandemic] OHCA events have occurred in Canton Sarajevo of which 297 (20.9 %) [180 (12.7%) before and 117 (8.2%) during COVID-19 pandemic] obtained ROSC. After a 30-day period following the ROSC) it was observed that the predominant outcome, accounting for 181 (12.7%) [106 (7.4%) before and 75 (5.2%) during COVID-19 pandemic] of cases, was a complete recovery. An examination before and during COVID-19 pandemic revealed a decline in OHCA during the year 2021 and 2022 when COVID-19 pandemic was at its highest in the country Being younger, quicker EMT response time and individuals with the initial rhythm of VF or VT were significantly associated with obtaining ROSC (p<0.05). Only 48 (3.3%) of 1418 OHCA events were assisted by bystanders There was no report of AED usage.

Conclusion

In conclusion, our investigation highlights the impact of the COVID-19 pandemic on OHCA events in Canton Sarajevo, revealing a decrease in OHCA incidence and a reduction in cases achieving ROSC. Notably, EMT response time was shorter during the pandemic.

This comprehensive review thoroughly examines post-resuscitation care in pediatric ICUs (PICUs) following cardiac arrest. The analysis encompasses adherence to resuscitation guidelines, advances in therapeutic interventions, and the nuanced management of neurological, cardiovascular, and respiratory considerations during the immediate post-resuscitation phase. Delving into the complexities of long-term outcomes, cognitive and developmental considerations, and rehabilitation strategies, the review emphasizes the importance of family-centered care for pediatric survivors. A call to action is presented, urging continuous education, research initiatives, and quality improvement efforts alongside strengthened multidisciplinary collaboration and advocacy for public awareness. Through implementing these principles, healthcare providers and systems can collectively contribute to ongoing advancements in pediatric post-resuscitation care, ultimately improving outcomes and fostering a culture of excellence in pediatric critical care.

Family history, socioeconomic factors, comorbidities, health behaviors, and the risk of sudden cardiac arrest

Genetic, environment, and behaviour factors have a role in causing sudden cardiac arrest (SCA). We aimed to determine the strength of the association between various risk factors and SCA incidence. We conducted a multicentre case-control study at 17 hospitals in Korea from September 2017 to December 2020. The cases included out-of-hospital cardiac arrest aged 19-79 years with presumed cardiac aetiology. Community-based controls were recruited at a 1:1 ratio after matching for age, sex, and urban residence level. Multivariable conditional logistic regression analysis was conducted. Among the 1016 cases and 1731 controls, 948 cases and 948 controls were analysed. A parental history of SCA, low educational level, own heart disease, current smoking, and non-regular exercise were associated with SCA incidence (Adjusted odds ratio [95% confidence interval]: 2.51 [1.48-4.28] for parental history of SCA, 1.37 [1.38-2.25] for low edication level, 3.77 [2.38-5.90] for non-coronary artery heart disease, 4.47 [2.84-7.03] for coronary artery disease, 1.39 [1.08-1.79] for current smoking, and 4.06 [3.29-5.02] for non-regular exercise). Various risk factors related to genetics, environment, and behaviour were independently associated with the incidence of SCA. Establishing individualised SCA prevention strategies in addition to general prevention strategies is warranted.
