Introduction: Immediate bystander cardiopulmonary resuscitation (CPR) is essential for the good outcome of sudden cardiac arrest victims. Current guidelines recommend dispatch-assisted CPR (DACPR). Its quality, however, varies from case to case. The aim of this study was todetermine the effectiveness of dispatch coaching on the quality of CPR by lay rescuers. Methods: We conducted a DACPR simulation study. Participants with no prior CPR training within 1 year were assigned randomly to one of two DACPR simulations (No Coaching Group: callers were told to perform CPR and the dispatcher sometimes confirmed if the caller was performing CPR or Coaching Group: the dispatcher coached, encouraged, and counted out loud with a metronome). The study participants performed CPR for 2 minutes under the study dispatcher. All performances were recorded by video camera and Resusci Anne® QCPR (Laerdal, Norway). Results: Forty-nine participants aged 20s to 50s were recruited, and 48 completed the simulation (Coaching Group, 27, 9 males and No Coaching Group, 21, 16 males). The average rate of chest compressions was 102.5/min in Coaching Group and 109.3/min in No Coaching group (p=0.270). The average compression depth was slightly deeper in Coaching group (43.0mm vs 41.5mm, p=0.695). When compared the average depth of the first 10 compressions to the total average in each group, the depth significantly improved in Coaching group while that decreased in No Coaching Groups (38.4mm to 43.0mm; p=0.020, 42.3mm to 41.5mm; p=0.431, respectively). The chest compression fraction was also high in Coaching Group (99.4% vs 93.0%, p=0.005). Conclusions: Participants in Coaching Group performed better CPR compared to No Coaching Group in terms of high flow fraction. Although the average compression depth was below the guideline recommendation in both groups, it significantly improved in Coaching group. This study indicates that dispatch coaching can optimize the performance of bystander CPR.

Abstract Background Immediate bystander cardiopulmonary resuscitation (CPR) is essential for survival from sudden cardiac arrest. Current CPR guidelines recommend that dispatchers assist lay rescuers performing CPR (dispatch-assisted CPR: DACPR), which can double the frequency of bystander CPR. Laypersons, however, are not familiar with receiving CPR instructions from dispatchers. DACPR training can be beneficial for lay rescuers, but this needs to be validated. The aim of this study was to determine the effectiveness of brief DACPR training for lay rescuers in addition to a standard CPR training course. Methods We conducted a randomized DACPR simulation pilot study. Participants with no CPR training within 1 year prior to this study were assigned randomly to one of two 90-minute CPR training courses (DACPR Group: a standard CPR course including DACPR training for 10 minutes or Standard Group: a standard CPR course with a simple lecture of dispatchers’ role). In the DACPR Group, participants practiced DACPR through role-playing of a dispatcher and an emergency caller. Six months after the training, the subjects in both groups performed CPR for 2 minutes under instruction by off-duty dispatchers. Results Out of the 66 participants, 59 (DACPR Group; 30, Standard Group; 29) completed the simulation. The CPR quality was similar between the two groups. However, the median time interval between call receipt and the first dispatch-assisted compression was faster in the DACPR group (108 s vs. 129 s, p = 0.042). Conclusions This brief DACPR training can be effective for lay rescuers to start chest compressions more quickly.

ObjectivesThe incidence of bystander cardiopulmonary resuscitation (CPR) is low in China. CPR training could improve public attitudes and willingness, but at present, the attitudes of the public after online training are unclear. This study investigated individual attitudes towards CPR, the willingness to perform it in emergencies along with the main obstacles and the overall effects of online training.DesignQuestionnaires were distributed to investigate the public attitudes and willingness towards performing bystander CPR.SettingQuestionnaires were accessible after the online course ‘First Aid’.Participants1888 students who attended ‘First Aid’ from December 2019 to 1 January 2020 and then completed the questionnaire voluntarily.ResultsThe majority understood CPR (96.7%) and displayed a willingness to learn (98.4%) and to disseminate CPR knowledge (82.0%). Characteristics associated with more positive attitudes included women, the 26–35-year olds and those in medical-related occupations (p<0.05). Only 34.8% had CPR training before. Most people would willingly perform CPR on a close family member. Compared with the standard CPR (S-CPR), the public preferred chest compression-only CPR (CO-CPR) (p<0.01). The top three obstacles to performing CO-CPR were lack of confidence (26.7%), fear of harming the victim (23.4%) and causing legal trouble (20.7%), while regarding S-CPR, fear of disease transmission (22.9%) ranked second. Women, those in poor health and in medical-related occupations, were more likely to perform CPR (p<0.05). The confidence to perform CPR was improved remarkably after online training (p<0.05).ConclusionsThe overwhelming majority of respondents showed positive attitudes and willingness towards CPR. In some cases, there is still reluctance, especially towards S-CPR. Obstacles arise mainly due to lack of confidence in administering CPR, while online CPR training can markedly improve it. Therefore, we should focus on disseminating CPR knowledge, targeting those who are less willing to perform CPR and helping overcome their obstacles by online training.

Introduction The aim of this study was to determine the effect of hand positioning on the quality of external chest compression (ECC) by novice rescuers. Methods This observational simulation study was conducted for 117 included participants. After completion of an adult cardiopulmonary resuscitation (CPR) training program for 3-h, the participants selected which of their hands would be in contact with the mannequin during ECC and performed 5 cycles of single rescuer CPR on a recording mannequin. The participants were assigned to 2 groups: the dominant hand group (DH; n=40) and the non-dominant hand group (NH; n=29). The depth and rate of ECC were analysed to compare the effectiveness of ECC between 2 groups. Results The rate of ECC was significantly faster in the DH group (mean, 117.3 ±11.4/min) than in the NH group (mean, 110.9±12.2/min) (p=0.028). However, the depth of ECC in the dominant hand group (mean, 52.4±5.9 mm) was not significantly different from that in the non-dominant hand group (mean, 50.8±6.0 mm) (p=0.287). Similarly, the portion of ECC with inadequate depth in the dominant hand group (mean, 1.8±4.3%) was not significantly different from that in the non-dominant hand group (mean, 5.3±15.6%) (p=0.252). Conclusions ECC can be performed with an acceptably higher rate of compressions when the dominant hand of the novice rescuer is placed in contact with the sternum. However, the position of the dominant hand does not affect the depth of ECC. (Hong Kong j.emerg.med. 2014;21:382-386)

Context:  Performance of quality cardiopulmonary resuscitation is essential for improving patient outcomes. Performing compressions over football equipment inhibits compression depth and rate, but lacrosse equipment has not yet been studied. Objective:  To assess the effect of lacrosse shoulder pads on the ability to provide quality chest compressions on simulation manikins. Design:  Crossover study. Setting:  Simulation laboratory. Patients or Other Participants:  Thirty-six athletic trainers (12 men: age = 33.3 ± 9.7 years; 24 women: age = 33.4 ± 9.8 years). Main Outcome Measure(s):  No shoulder pads (NSP), Warrior Burn Hitman shoulder pads (WSP), and STX Cell II shoulder pads (SSP) were investigated. Outcomes were chest-compression depth (millimeters), rate (compressions per minute), rating of perceived exertion (0−10), hand-placement accuracy (%), and chest recoil (%). Results:  We observed a difference in mean compression depth among shoulder-pad conditions (F2,213 = 3.73, P = .03, ω2 = 0.03), with a shallower depth during the WSP (54.1 ± 5.8 mm) than the NSP (56.8 ± 5.7 mm; P = .02) trials. However, no differences were found in mean compression rate (F2,213 = 0.87, P = .42, ω2 = 0.001, 1–β = .20). We noted a difference in rating of perceived exertion scores (F2,213 = 16.41, P &lt; .001, ω2 = 0.12). Compressions were more difficult during the SSP condition (4.1 ± 1.3) than during the NSP (2.9 ± 1.2; P &lt; .001) and WSP (3.3 ± 1.1; P = .002) conditions. A difference was present in hand-placement accuracy among the 3 shoulder-pad conditions (χ22 = 11.14, P = .004). Hand-placement accuracy was better in the NSP than the SSP condition (P = .002) and the SSP than the WSP condition (P = .001). Conclusions:  Lacrosse shoulder pads did not inhibit the ability to administer chest compressions with adequate rate and depth. With appropriate training to improve hand placement, the pads may be left in place while cardiopulmonary resuscitation is initiated during sudden cardiac arrest.

AbstractObjectivesWe aimed to explore whether a) step stool use is associated with improved cardiopulmonary resuscitation (CPR) quality; b) provider adjusted height is associated with improved CPR quality; and if associations exist, c) determine whether just-in-time (JIT) CPR training and/or CPR visual feedback attenuates the effect of height and/or step stool use on CPR quality.MethodsWe analysed data from a trial of simulated cardiac arrests with three study arms: No intervention; CPR visual feedback; and JIT CPR training. Step stool use was voluntary. We explored the association between 1) step stool use and CPR quality, and 2) provider adjusted height and CPR quality. Adjusted height was defined as provider height + 23 cm (if step stool was used). Below-average height participants were ≤ gender-specific average height; the remainder were above average height. We assessed for interaction between study arm and both adjusted height and step stool use.ResultsOne hundred twenty-four subjects participated; 1,230 30-second epochs of CPR were analysed. Step stool use was associated with improved compression depth in below-average (female, p=0.007; male, p<0.001) and above-average (female, p=0.001; male, p<0.001) height providers. There is an association between adjusted height and compression depth (p<0.001). Visual feedback attenuated the effect of height (p=0.025) on compression depth; JIT training did not (p=0.918). Visual feedback and JIT training attenuated the effect of step stool use (p<0.001) on compression depth.ConclusionsStep stool use is associated with improved compression depth regardless of height. Increased provider height is associated with improved compression depth, with visual feedback attenuating the effects of height and step stool use.

Objectives‘Quality Cardiopulmonary Resuscitation (QCPR) Classroom’ was recently introduced to provide higher-quality Cardiopulmonary Resuscitation (CPR) training. This study aimed to examine whether novel QCPR Classroom training can lead to higher chest-compression quality than standard CPR training.DesignA cluster randomised controlled trial was conducted to compare standard CPR training (control) and QCPR Classroom (intervention).SettingLayperson CPR training in Japan.ParticipantsSix hundred forty-two people aged over 15 years were recruited from among CPR trainees.InterventionsCPR performance data were registered without feedback on instrumented Little Anne prototypes for 1 min pretraining and post-training. A large classroom was used in which QCPR Classroom participants could see their CPR performance on a big screen at the front; the control group only received instructor’s subjective feedback.Primary and secondary outcome measuresThe primary outcomes were compression depth (mm), rate (compressions per minute (cpm)), percentage of adequate depth (%) and recoil (%). Survey scores were a secondary outcome. The survey included participants’ confidence regarding CPR parameters and ease of understanding instructor feedback.ResultsIn total, 259 and 238 people in the control and QCPR Classroom groups, respectively, were eligible for analysis. After training, the mean compression depth and rate were 56.1±9.8 mm and 119.2±7.3 cpm in the control group and 59.5±7.9 mm and 116.8±5.5 cpm in the QCPR Classroom group. The QCPR Classroom group showed significantly more adequate depth than the control group (p=0.001). There were 39.0% (95% CI 33.8 to 44.2; p<0.0001) and 20.0% improvements (95% CI 15.4 to 24.7; P<0.0001) in the QCPR Classroom and control groups, respectively. The difference in adequate recoil between pretraining and post-training was 2.7% (95% CI −1.7 to 7.1; pre 64.2±36.5% vs post 66.9%±34.6%; p=0.23) and 22.6% in the control and QCPR Classroom groups (95% CI 17.8 to 27.3; pre 64.8±37.5% vs post 87.4%±22.9%; p<0.0001), respectively.ConclusionsQCPR Classroom helped students achieve high-quality CPR training, especially for proper compression depth and full recoil. For good educational achievement, a novel QCPR Classroom with a metronome sound is recommended.

Background: Similar to many Asian cities, there is no statutory provision for the determination of the duty borne by bystander first aiders when assisting victims in Hong Kong. Objectives: The aim of this study was to explore the views of a Good Samaritan Law by first-aid learners in Hong Kong. Methods: A cross-sectional survey was conducted among first-aid course participants from the two largest training providers in Hong Kong using a self-administered questionnaire. Results: In total, 1223 questionnaires were completed and returned. Only 12.1% (147/1211) of participants have ever heard of Good Samaritan Law. After a short description of Good Samaritan Law was provided, 71.4% (848/1188) agreed or strongly agreed on a Likert-type scale that a Good Samaritan Law is necessary; 95.2% (1148/1223) support the enactment of a Good Samaritan Law in Hong Kong. Conclusion: The majority of first-aid learners in Hong Kong supported the enactment of Good Samaritan Law. Overcoming the fear of litigation and improving bystander cardiopulmonary resuscitation rate is a priority for improving survival rates from sudden cardiac arrest in Hong Kong.

Background: Sports-related sudden cardiac arrest (sport SCA) has always attracted attention and the United States and European Union have developed divergent strategies for prevention over the last decade; notably regarding screening of younger athletes but also for SCA prevention in middle-aged and senior individuals. In this context, the extent to which outcomes of sports SCA differ between Europe and the USA have not been characterized. Methods: SCA cases aged 15-75 years were identified in two large prospective, population-based SCA programs, one in the Paris region (Paris-SDEC) and the other in a Northwestern US metro region (Oregon-SUDS) between 2002 and 2012. Cases of SCA, occurring during sports activity were compared between the two regions. Results: Of the 7,357 cases studied, 290 (4%) occurred during sports, with very similar proportions in both regions: 86 out of 1,894 (4.5%) in Oregon and 204 out of 5,463 (3.8%) in Paris. Subjects’ characteristics of cases in both programs were very similar (Paris vs. Oregon, respectively, for all results following), regarding age (50.7±14 vs. 50.4±13 years, P=0.55), male proportion (94%vs. 92%, P=0.53), past medical history of ≥2 cardiovascular risk factors (16% vs. 23%, P=0.16) and/or heart disease (10% vs. 8%, P=0.55). There was a high proportion of witnessed events in both populations (89% vs. 90%, P=0.94). However, we observed significant differences with more bystander cardiopulmonary resuscitation in Paris (63% vs. 48%, P=0.02), faster response time in Oregon (8.3±6 vs. 6.9±4 min, P=0.05), and more initially shockable rhythms in Oregon (52% vs. 70%, P=0.006). Overall, resuscitation outcomes were very similar for return of spontaneous circulation (26% vs. 33%, P=0.21) and survival to hospital discharge (27% vs. 26%, P=0.80). Conclusions: On either side of the Atlantic, burden and characteristics of sports-related SCA are very similar. Survival rates are approximately one in four cases. Optimizing bystander cardiopulmonary resuscitation rates and emergency response times could further improve outcomes. Deployment of uniform, effective strategies for screening and prevention are likely to make the greatest impact on sports SCA.

Introduction: Immediate bystander cardiopulmonary resuscitation (CPR) is essential for the good outcome of sudden cardiac arrest victims. Current guidelines recommend dispatch-assisted CPR (DA-CPR), which can double the frequency of bystander CPR. Laypersons, however, are not familiar with how dispatchers provide CPR instructions. DA-CPR training may be effective at spreading DA-CPR, but this needs to be validated. The aim of this study was to determine the effectiveness of brief DA-CPR training in addition to a standard CPR training course. Methods: We conducted a DA-CPR simulation study. Participants with no prior CPR training within 1 year were assigned randomly to one of two 90-min CPR training courses (DA-CPR Group: a standard CPR course with 10-min DA-CPR training or Standard Group: a standard CPR course with a simple introduction to how dispatchers deal with emergency calls). In the DA-CPR Group, the participants practiced the role of a dispatcher and an emergency caller. At 6 months after training, the subjects performed CPR for 2 min under instruction from off-duty dispatchers. Results: Of the 66 participants, 59 (DA-CPR Group, 30; Standard Group, 29) completed the simulation at 6 months after training. The median time intervals between call receipt and cardiac arrest recognition or instruction for chest compressions by dispatchers were similar between both groups. However, the subjects in the DA-CPR Group provided the first compression more quickly (median time interval between call receipt and the first dispatch-assisted compression: 108 vs. 129 s, respectively, p < 0.05 Mann-Whitney U test). The quality of chest compressions was, however, similar between both groups. Conclusions: All participants could perform DA-CPR at 6 months after training, but those in the DA-CPR Group started chest compressions more quickly. DA-CPR training might be effective for the immediate development of better cooperation between a layperson and a dispatcher.
