Interventions to improve the quality of bystander cardiopulmonary resuscitation: A systematic review

Abstract

Background Performing high-quality bystander cardiopulmonary resuscitation (CPR) improves the clinical outcomes of victims with sudden cardiac arrest. Thus far, no systematic review has been performed to identify interventions associated with improved bystander CPR quality. Methods We searched Ovid MEDLINE, Ovid EMBASE, EBSCO CINAHL, Ovid PsycInfo, Thomson Reuters SCI-EXPANDED, and the Cochrane Central Register of Controlled Trials to retrieve studies published from 1 January 1966 to 5 October 2018 associated with interventions that could improve the quality of bystander CPR. Data regarding participant characteristics, interventions, and design and outcomes of included studies were extracted. Results Of the initially identified 2,703 studies, 42 were included. Of these, 32 were randomized controlled trials. Participants included adults, high school students, and university students with non-medical professional majors. Interventions improving bystander CPR quality included telephone dispatcher-assisted CPR (DA-CPR) with simplified or more concrete instructions, compression-only CPR, and other on-scene interventions, such as four-hand CPR for elderly rescuers, kneel on opposite sides for two-person CPR, and CPR with heels for a tired rescuer. Devices providing real-time feedback and mobile devices containing CPR applications or software were also found to be beneficial in improving the quality of bystander CPR. However, using mobile devices for improving CPR quality or for assisting DA-CPR might cause rescuers to delay starting CPR. Conclusions To further improve the clinical outcomes of victims with cardiac arrest, these effective interventions may be included in the guidelines for bystander CPR.

Barriers to bystander CPR in deprived communities: Findings from a qualitative study

“…However, existing research has focused on the general population and lacks detail regarding the deprived communities where BCPR is less likely to be performed. For example, a recent systematic review by Chen et al, (2019) [17] of interventions to improve the quality of BCPR made no comment on interventions that would be more appropriate for deprived communities. Becker et al (2019) [11], suggest that people living in more affluent areas are more likely to be CPR trained and, therefore, more confident to administer CPR.…”

Basic Life-Support Learning in Undergraduate Students of Sports Sciences: Efficacy of 150 Minutes of Training and Retention after Eight Months

“…Although there is no ideal method for learning BLS [7,8], there are certain aspects that have been shown to be effective. For example, feedback devices are especially useful in the learning of CPR skills as they correct the technique in real time and improve its learning [9] by correcting parameters such as the compression rate, depth, full recoil and hand positions [2].…”

Is Mouth-to-mouth Ventilation Effective in Lifeguards?Comparing the Effects between 30:2 Algorithm Versus Hands-only. A Simulation Study

“…However, it should be taken into account that these results were due to the calculation of the arithmetic mean of all the ventilation. It is necessary to point out that in most cases, hyperventilation was produced, which, -according to numerous studies [29][30][31] -was the most expected outcome (followed by regurgitation) when it is performed by non-trained personnel, and even when performed by professionals [31]. Nevertheless, it should be known that when this maneuver was not performed, the volume insufflated was found to be below the optimum levels and when it was performed, the most repeated result was hyperventilation, as mentioned above.…”
