ABSTRAKKejadian henti jantung dapat terjadi dimana saja baik di rumah sakit maupun di luar rumah sakit atau Out-of-Hospital Cardiac Arrest (OHCA). Usaha untuk meningkatkan survival rate kejadian henti jantung adalah pemberian Cardiopulmonary resuscitation (CPR)/ resusitasi jantung paru (RJP) yang berkualitas. Faktor yang mempengaruhi seseorang untuk mau menjadi bystander CPR bukan hanya terkait pengetahuan dan teknik melakukan CPR namun juga dipengaruhi oleh faktor sosial, kerelaan melakukan, kesiapan psikologis dan faktor lainnya seperti aspek etik dan hukum. Tujuan penelitian ini untuk mengetahui pengaruh persepsi perlindungan hukum dan aspek etik terhadap keinginan perawat dalam memberikan tindakan CPR pada kejadian Out-of-Hospital Cardiac Arrest. Penelitian menggunakan desain cross-sectional dengan metode kuisioner yang dikembangkan oleh peneliti dan menggunakan total sampling yang melibatkan seluruh perawat IGD RSUD Budhi Asih sebanyak 30 orang. Analisis menggunakan uji Fisher’s Exact dan Cochran-Mantel Haenszel. Hasil penelitian menunjukkan mayoritas responden (56,7%) memiliki persepsi yang negatif terhadap perlindungan hukum terhadap bystander CPR pada OHCA. Meskipun demikian, perawat cenderung memiliki persepsi yang positif ketika menjawab pertanyaan terkait isu etik CPR pada korban anak-anak, wanita maupun lansia. Sebanyak 43,33% (13 perawat) memiliki keinginan positif untuk melakukan CPR pada OHCA sementara 56,67% (17 perawat) lainnya memiliki keinginan negatif sebagai bystander CPR. Hasil uji Cochran-Mantel Haenszel menunjukkan persepsi terhadap perlindungan hukum mempengaruhi keinginan perawat dalam memberikan CPR pada OHCA dan akan diperbesar kemungkinan memberikan CPR apabila perawat tersebut berusia ≥ 30 tahun (p 0,014; OR 14,133; 95% CI 2,081-95,947) dan memiliki masa kerja ≥ 5 tahun (p 0,008; OR 25,667; 95% CI 2,253-292,462). Promosi mengenai aspek legal dan etik, serta landasan hukum perlindungan terhadap bystander CPR menjadi penting untuk dapat meningkatkan keinginan perawat dan jumlah bystander CPR. ABSTRACTCardiac arrest can occur anywhere in the hospital or outside the hospital, which is called Out-of-Hospital Cardiac Arrest (OHCA). An effort to increase the survival rate of cardiac arrest is the provision of quality Cardiopulmonary resuscitation (CPR). Factors that influence a person's willingness to become a bystander CPR are not only related to the knowledge and techniques of conducting CPR but are also influenced by social factors, willingness, psychological readiness, and other factors such as ethical and legal aspects. The purpose of this study is to determine the effect of perceptions of legal protection and ethical issues on the nurses' willingness to provide CPR in the OHCA incident. This study used a cross-sectional design using a questionnaire developed by researchers, conducted at Emergency Department Budhi Asih Regional Hospital in East Jakarta, and used a total sampling method involving 30 ED nurses. Fisher's Exact and Cochran-Mantel Haenszel tests were used to analyze the data. The study findings show that the majority of respondents (56.7%) have a negative perception of the legal protection of bystander CPR in OHCA. However, nurses have a positive perception when answering questions related to the ethical issue of CPR in victims of children, women, and the elderly. 43.33% (13 nurses) have a positive willingness to perform CPR on OHCA, while 56.67% (17 nurses) have a negative willingness as a bystander CPR. The results of the Cochran-Mantel Haenszel test show that perceptions of legal protection may influence nurses' willingness to provide CPPR to OHCA patient, and it will increase the likelihood of giving CPR if the nurse age is ≥ 30 years old (p 0.014; OR 14,133; 95% CI 2,081-95,947) and has been working for ≥ 5 years (p 0.008; OR 25,667; 95% CI 2,253-292,462). Promotion of the legal aspects, ethical issues, and protection to bystander CPR are essential to increase the willingness of nurses and the number of bystander CPR.

Abstract Background Out-of-hospital cardiac arrest (OHCA), a global health problem with a survival rate ranging from 2 to 22% across different countries, has been a leading cause of premature death for decades. The aim of this study was to evaluate the trends of survival after OHCA over time and its relationship with bystander cardiopulmonary resuscitation (CPR), initial shockable rhythm, return of spontaneous circulation (ROSC), and survived event. Methods In this prospective observational study, data of OHCA patients were collected following the “Utstein style” by the Beijing, China, Emergency Medical Service (EMS) from January 2011 (data from February to June in 2011 was not collected) to October 2016. Patients who had a cardiac arrest and for whom an ambulance was dispatched were included in this study. All cases were followed up to determine hospital discharge or death. The trend of OHCA survival was analyzed using the Chi-square test. The relationship among bystander CPR, initial shockable rhythm, ROSC, survived event, and OHCA survival rate was analyzed using multivariate path analyses with maximum standard likelihood estimation. Results A total of 25,421 cases were transferred by the Beijing EMS; among them, 5042 (19.8%) were OHCA (median age: 78 years, interquartile range: 63–85, 60.1% male), and 484 (9.6%) received bystander CPR. The survival rate was 0.6%, which did not improve from 2012 to 2015 (P = 0.569). Overall, bystander CPR was indirectly associated with an 8.0% (β = 0.080, 95% confidence interval [CI] = 0.064–0.095, P = 0.002) increase in survival rate. The indirect effect of bystander CPR on survival rate through survived event was 6.6% (β = 0.066, 95% CI = 0.051–0.081, P = 0.002), which accounted for 82.5% (0.066 of 0.080) of the total indirect effect. With every 1 increase in survived event, the possibility of survival rate will directly increase by 53.5% (β = 0.535, 95% CI = 0.512–0.554, P = 0.003). Conclusions The survival rate after OHCA was low in Beijing which has not improved between 2012 and 2015. The effect of bystander CPR on survival rate was mainly mediated by survived event.

ObjectiveThe purpose of this study was to assess the trends in outcomes of out-of-hospital cardiac arrest (OHCA) in Beijing over 5 years.DesignCross-sectional study.MethodsAdult patients with OHCA of all aetiologies who were treated by the Beijing emergency medical service (EMS) between January 2013 and December 2017 were analysed. Data were collected using the Utstein Style. Cases were followed up for 1 year. Descriptive statistics were used to characterise the sample and logistic regression was performed.ResultsOverall, 5016 patients with OHCA underwent attempted resuscitation by the EMS in urban areas of Beijing during the study period. Survival to hospital discharge was 1.2% in 2013 and 1.6% in 2017 (adjusted rate ratio=1.0, p for trend=0.60). Survival to admission and neurological outcome at discharge did not significantly improve from 2013 to 2017. Patient characteristics and the aetiology and location of cardiac arrest were consistent, but there was a decrease in the initial shockable rhythm (from 6.5% to 5.6%) over the 5 years. The rate of bystander cardiopulmonary resuscitation (CPR) increased steadily over the years (from 10.4% to 19.4%).ConclusionSurvival after OHCA in urban areas of Beijing did not improve significantly over 5 years, with long-term survival being unchanged, although the rate of bystander CPR increased steadily, which enhanced the outcomes of patients who underwent bystander CPR.

Background: In Japan, extracorporeal cardiopulmonary resuscitation (ECPR) became popular for cardiac arrest patients who resist conventional advanced life supports. Regardless of many clinical experiences, there has been no previous systematic literature review. Methods: Case series, reports and proceedings of scientific meeting about ECPR for out-of-hospital cardiac arrest written in Japanese between January 1, 1983 and July 31, 2007 were collected with Japana Centra Revuo Medicina (medical publication database in Japan) and review by experts. The outcome and characteristics of the patients were investigated, and the influence of publication bias of the case series study was also examined by the Funnel Plot method. Results: There were 951 out-of-hospital cardiac arrest patients who received ECPR in 92 reports (including 59 case series and 33 case reports) during the period. The average of age was 38.1 (4 – 88) years old and 76.1% was male. Three hundreds and eighty-one cases (40.1%) were arrests of cardiac etiology, and 212 were non-cardiac (22.3%). The cause of arrest was not described in other 37.6%. Excluding reports for only one case, weighted survival rate at discharge of 792 cases those were clearly described the outcome was 39.5±10.0%. When the relationship between the number of cases and the survival rate at discharge in each 59 case series study was shown in figure by the Funnel Plot method, the plotted data presented the reverse-funnel type that centered on the average of survival rate of all. Conclusions: The influence of publication bias of previous reports in Japan was relatively low. ECPR can greatly contribute to improve the outcome of out-of hospital cardiac arrests.

Background Bystander cardiopulmonary resuscitation (CPR) is a critical intervention to improve survival following out‐of‐hospital cardiac arrest. We evaluated the quality of bystander CPR and whether performance varied according to the number of bystanders or provision of telecommunicator CPR (TCPR). Methods and Results We investigated non‐traumatic out‐of‐hospital cardiac arrest occurring in a large metropolitan emergency medical system during a 6‐month period. Information about bystander care was ascertained through review of the 9‐1‐1 recordings in addition to emergency medical system and hospital records to determine bystander CPR status (none versus TCPR versus unassisted), the number of bystanders on‐scene, and CPR performance metrics of compression fraction and compression rate. Of the 428 eligible out‐of‐hospital cardiac arrest, 76.4% received bystander CPR including 43.7% unassisted CPR and 56.3% TCPR; 35.2% had one bystander, 33.3% had 2 bystanders, and 31.5% had ≥3 bystanders. Overall compression fraction was 59% with a compression rate of 88 per minute. CPR differed according to TCPR status (fraction=52%, rate=87 per minute for TCPR versus fraction=69%, rate=102 for unassisted CPR, P <0.05 for each comparison) and the number of bystanders (fraction=55%, rate=87 per minute for 1 bystander, fraction=59%, rate=89 for 2 bystanders, fraction=65%, rate=97 for ≥3 bystanders, test for trend P <0.05 for each metric). Additional bystander actions were uncommon to include rotation of compressors (3.1%) or application of an automated external defibrillator (8.0%). Conclusions Bystander CPR quality as gauged by compression fraction and rate approached guideline goals though performance depended upon the type of CPR and number of bystanders.

Background The mechanism by which bystander cardiopulmonary resuscitation (CPR) improves survival following out‐of‐hospital cardiac arrest is unclear. We hypothesized that ventricular fibrillation (VF) waveform measures, as surrogates of myocardial physiology, mediate the relationship between bystander CPR and survival. Methods and Results We performed a retrospective cohort study of adult, bystander‐witnessed patients with out‐of‐hospital cardiac arrest with an initial rhythm of VF who were treated by a metropolitan emergency medical services system from 2005 to 2018. Patient, resuscitation, and outcome variables were extracted from emergency medical services and hospital records. A total of 3 VF waveform measures (amplitude spectrum area, peak frequency, and median peak amplitude) were computed from a 3‐second ECG segment before the initial shock. Multivariable logistic regression estimated the association between bystander CPR and survival to hospital discharge adjusted for Utstein elements. Causal mediation analysis quantified the proportion of survival benefit that was mediated by each VF waveform measure. Of 1069 patients, survival to hospital discharge was significantly higher among the 814 patients who received bystander CPR than those who did not (0.52 versus 0.43, respectively; P <0.01). The multivariable‐adjusted odds ratio for bystander CPR and survival was 1.6 (95% CI, 1.2, 2.1), and each VF waveform measure attenuated this association. Depending on the specific waveform measure, the proportion of mediation varied: 53% for amplitude spectrum area, 31% for peak frequency, and 29% for median peak amplitude. Conclusions Bystander CPR correlated with more robust initial VF waveform measures, which in turn mediated up to one‐half of the survival benefit associated with bystander CPR. These results provide insight into the biological mechanism of bystander CPR in VF out‐of‐hospital cardiac arrest.

BackgroundSeveral Chinese cities have implemented dispatcher-assisted cardiopulmonary resuscitation (DA-CPR), although out-of-hospital cardiac arrest (OHCA) survival rates remain low. We aimed to assess the process compliance, barriers and outcomes of OHCA in one of the earliest implemented (DA-CPR) programmes in China.MethodsWe retrospectively reviewed OHCA emergency dispatch records of Suzhou emergency medical service from 2014 to 2015 and included adult OHCA victims (>18 years) with a bystander-witnessed atraumatic OHCA that was subsequently confirmed by on-site emergency physician. The circumstances and DA-CPR process related to the OHCA event were analysed. Dispatch audio records were reviewed to identify potential barriers to implementation during the DA-CPR process.ResultsOf the 151 OHCA victims, none survived. The median time from patient collapse to call for emergency services and that from call to provision of cardiopulmonary resuscitation instructions was 30 (IQR 20–60) min and 115 (IQR 90–153) s, respectively. Only 110 (80.3%) bystanders/rescuers followed the dispatcher instructions; of these, 51 (46.3%) undertook persistent chest compressions. Major barriers to following the DA-CPR instructions were present in 104 (68.9%) cases, including caller disconnection of the call, distraught mood or refusal to carry out either compressions or ventilations.ConclusionsThe OHCA survival rate and the DA-CPR process were far from optimal. The zero survival rate is disproportionally low compared with survival statistics in high-income countries. The prolonged delay in calling the emergency services negated and rendered futile any DA-CPR efforts. Thus, efforts targeted at developing public awareness of OHCA, calling for help and competency in DA-CPR should be increased.

Abstract Background Out-of-hospital cardiac arrest (OHCA) is a major public health concern in France, given that there are 61.5 cases per 100,000 inhabitants a year. The impact of bystander action, performed before the arrival of emergency medical services (EMS), on survival has never been studied in France. Purpose Determine whether bystander cardiopulmonary resuscitation (CPR), performed before the arrival of EMS, was correlated with an increased 30-day survival rate after an OHCA. Methods 24,885 out-of-hospital cardiac arrests witnessed in France from 1 January 2012 to 1 May 2018 were analysed to determine whether CPR, performed before the arrival of EMS, was correlated with survival. Data from the Electronic Registry of Cardiac Arrests was used. The association between the effect of CPR performed before the arrival of EMS and 30-day survival rate was studied, using propensity analysis (which included variables such as age and sex of the patient, location, cause, and year of cardiac arrest, initial cardiac rhythm, EMS response time and no-flow time). Results CPR was performed before the arrival of EMS in 14,904 cases (59.9%) and was not performed in 9,981 cases (40.1%). The 30-day survival rate was 10.2% when CRP was performed by bystanders versus 3.9% when CRP was not performed before the EMS arrival (p<0.001). CPR performed by bystanders was associated with an increased 30-day survival rate (odds ratio 1.269; 1.207 to 1.334). The effect of bystander CPR on survival Conclusion Bystander CPR performed before the arrival of EMS was associated with an increased 30-day survival rate after an out-of-hospital cardiac arrest in France.

Background: Little is known about the provision of care by law enforcement (LE) personnel within modern EMS systems. We evaluated LE performance of bystander CPR (BCPR) and associated outcomes in OHCA across Arizona. Methods: A total of 5,654 OHCA cases (1/1/2019-12/31/2019) were evaluated using the Save Hearts in Arizona Registry and Education (SHARE) cardiac arrest registry. Data were abstracted from all EMS patient care records (PCRs). If two parties provided BCPR, the first to give compressions was considered the provider for this analysis. Cases identified as “Stranger” or “Unknown” BCPR were manually evaluated for narrative data to identify BCPR provider when possible. Results: BCPR was provided in 2285 cases [48.8%; (95% CIs 47.4%, 50.3%)] after excluding 850 cases that occurred in healthcare facilities where personnel are duty-bound to provide CPR. LE provided BCPR in 444 patients [19.4% (17.8%, 21.1%)], second only to family/spouse [1143 pts; 50.0% (48.0%, 52.1%)]. Overall, 279 patients survived to hospital discharge [12.2%, (10.9%, 13.6%)]. The Table shows the rates of BCPR in each provider category and the associated rates of survival. Of note is that the rate of bystander AED use was more than four times higher in LE BCPR [6.3% (4.23%, 8.99%)] than family-provided BCPR [1.5% (0.87%, 2.37%; p < 0.0001)], but was still very low. Conclusions: In this statewide study that included more than 130 EMS agencies from frontier to urban settings, LE personnel were frequently involved in the care of OHCA patients within the 911 system response. To our knowledge, this magnitude of provision of BCPR by LE (nearly one in five BCPR cases) has not been reported previously. Furthermore, the consequential rate of LE response to OHCA provides the opportunity to significantly increase AED use. Our findings support the widespread and intentional training of LE in CPR and AED use and has the potential to improve survival in diverse settings.

Introduction: Multiple citizen responder (CR) programs worldwide which dispatch laypersons to out-of-hospital cardiac arrest (OHCA) to perform cardiopulmonary resuscitation (CPR) and use of automated external defibrillators (AEDs) were affected by the COVID-19 outbreak in 2020, but little is known about how the pandemic affected CR activation and initiation of bystander CPR and defibrillation. In Denmark, the CR program continued to run during lockdown but with the recommendation to perform chest-compression-only CPR in contrast to standard CPR including ventilations. We hypothesized that bystander interventions as CPR and AED usage decreased during the first COVID-19 lockdown in two regions of Denmark in the spring of 2020. Methods: All OHCAs from January 1, 2020 to June 30, 2020 with CR activation from the Danish Cardiac Arrest Registry and the National Citizen Responder database. Bystander CPR, AED usage, and CRs’ alarm acceptance rate during the national lockdown from March 11, 2020 to April 20, 2020 were compared with the non-lockdown period from January 1, 2020 to March 10, 2020 and from April 21 to June 30, 2020. Results: A total of 6,120 CRs were alerted in 443 (23/100.000 inhabitants) cases of presumed OHCA of which 256 (58%) were confirmed cardiac arrests. Bystander CPR remained equally high in the lockdown period compared with non-lockdown period (99% vs. 92%, p=0.07). Likewise, there was no change in bystander defibrillation (9% vs. 14%, p=0.4). There was a slight increase in the number of CRs who accepted an alarm (7 per alarm, IQR 4) during lockdown compared with non-lockdown period (6 per alarm, IQR 4), p=0.0001. The proportion of patients achieving return of spontaneous circulation at hospital arrival was also unchanged (lockdown 23% vs non-lockdown 23%, p=1.0) (Table 1). Conclusion: Bystander initiated resuscitation rates did not change during the first COVID-19 lockdown in Denmark for OHCAs where CRs were activated through a smartphone app.
