Risk and ROSC - Legal implications of bystander CPR

"Shrink back is not my intention": a qualitative exploration of Chinese security guards' experiences with bystander CPR

BACKGROUND

Out-of-hospital cardiac arrest (OHCA) is a major public health burden worldwide. Promoting bystander cardiopulmonary resuscitation (B-CPR) is a key element in improving the survival rate of OHCA. The security guard is a specific population in China that plays a significant role as bystanders in public settings. However, less is known about their experiences regarding B-CPR intention and performance. This study aimed to explore the experiences and perspectives of Chinese security guards regarding B-CPR and identify barriers to its performance.

METHODS

Fifteen in-depth interviews were conducted with security guards in various public settings, including hospitals, residential living areas, office buildings, and public transportation stations. All interviews were audio recorded. Two researchers independently analyzed the transcripts through deductive and inductive content analysis. Informed by the "Intention-focused" model of B-CPR performance, deductive content analysis was initially performed to identify categories that align with the theoretical framework and thereby validate the theory. Subsequently, inductive content analysis was applied to code newly discovered content, therefore enriching the theory.

RESULTS

An "intention & performance-focused" model of B-CPR was developed. It was revealed that security personnel were more inclined to perform CPR without hesitation when the victim was a trusted individual. However, when faced with unfamiliar individuals, they tended to shrink back due to various barriers. Specifically, four layers of barriers to CPR performance were identified, encompassing security personnel factors, victim-related factors, organizational factors, and societal factors. Participants also shared their perspectives on the desired CPR training, including trainers, training contents, training formats, and training incentives.

CONCLUSION

Security guards should receive comprehensive CPR training to maximize their occupational value. In addition to strengthening CPR-related training, which includes theoretical knowledge and hands-on practice, psychological coping skills for managing overwhelming emotions and understanding relevant laws are also essential training elements that cannot be overlooked. When developing relevant intervention strategies, policies, and regulations, it's critical to consider the country's context and the cooperation of the organization where the security guard is employed. The model developed in this study can provide a reference for designing interventions and policy to improve the B-CPR intention and performance for other specific groups.

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.

Fears and Concerns of Bystanders to Help People Injured in Traffic Accidents: A Qualitative Descriptive Study

In most traffic accidents, bystanders arrive at the scene before the rescuers. If they provide the right help, they can play an important and effective role in reducing the number of deaths and complications caused by these accidents. However, in many cases, fears and concerns prevent bystanders from providing assistance. This study aims to investigate and understand the fears and concerns of bystanders when they decide to help in traffic accidents. In 2022, this study was carried out in Iran using a qualitative content analysis approach. The data was collected through semistructured interviews. Participants were 15 males and females who had experience providing assistance in traffic accidents. Interviews, after digital recording, were transcribed verbatim. A purposeful and theoretical sampling method was performed. Data analysis and the determination of codes, categories, and subcategories were done using qualitative analysis software. O'Brien's qualitative research reporting standard was used. The results of the study include a category of fears and concerns and five subcategories. The subcategories include fear and concern caused by lack of information, fear of legal troubles, stress caused by previous experience, fear and anxiety caused by anticipation, and anxiety of unknown origin. The results of this study showed that some of the fears and concerns of the bystanders were related to a lack of information about providing assistance. By increasing bystanders' information about assistance, such as first aid training, fear and anxiety caused by a lack of information can be reduced. Another part of the fear and concern of bystanders is due to legal issues. Passing and implementing laws that protect bystanders can help reduce this fear and concern. Bystanders should be trained to provide assistance according to the rules of assistance so that they do not get into legal problems. A part of the bystander's fear and concern stems from their previous experiences providing assistance in traffic accidents. These experiences can also affect the fear and anxiety caused by anticipation. It is necessary to conduct more studies on the role of bystanders' experiences in creating fear and anxiety in them, as well as their effect on anticipatory fear.

Understanding the Importance of the Lay Responder Experience in Out-of-Hospital Cardiac Arrest: A Scientific Statement From the American Heart Association

Bystander cardiopulmonary resuscitation (CPR) is critical to increasing survival from out-of-hospital cardiac arrest. However, the percentage of cases in which an individual receives bystander CPR is actually low, at only 35% to 40% globally. Preparing lay responders to recognize the signs of sudden cardiac arrest, call 9-1-1, and perform CPR in public and private locations is crucial to increasing survival from this public health problem. The objective of this scientific statement is to summarize the most recent published evidence about the lay responder experience of training, responding, and dealing with the residual impact of witnessing an out-of-hospital cardiac arrest. The scientific statement focuses on the experience-based literature of actual responders, which includes barriers to responding, experiences of doing CPR, use of an automated external defibrillator, the impact of dispatcher-assisted CPR, and the potential for postevent psychological sequelae. The large body of qualitative and observational studies identifies several gaps in crucial knowledge that, if targeted, could increase the likelihood that those who are trained in CPR will act. We suggest using the experience of actual responders to inform more contextualized training, including the implications of performing CPR on a family member, dispelling myths about harm, training and litigation, and recognition of the potential for psychologic sequelae after the event.

The impact of bystander cardiopulmonary resuscitation on patients with out-of-hospital cardiac arrests

Out-of-hospital cardiac arrest (OHCA) is one of the leading causes of death around the world. Bystander cardiopulmonary resuscitation (CPR) is an independent factor to improve OHCA survival. However, the prevalence of bystander CPR remains low worldwide. Community interventions such as mandatory school CPR training or targeting CPR training to family members of high-risk cardiac patients are possible strategies to improve bystander CPR rate. Real-time feedback, hands-on practice with a manikin, and metronome assistance may increase the quality of CPR. Dispatcher-assistance and compression-only CPR for untrained bystanders have shown to increase bystander CPR rate and increase survival to hospital discharge. After return of spontaneous circulation, targeted temperature management should be performed to improve neurological function. This review focuses on the impact of bystander CPR on clinical outcomes and strategies to optimize the prevalence and quality of bystander CPR.
