Bystander Cardiopulmonary Resuscitation

Abstract Background The International Liaison Committee on Resuscitation recommends that dispatchers provide instructions to perform compression-only cardiopulmonary resuscitation (CPR) to callers responding to adults with out-of-hospital cardiac arrest (OHCA). This study aimed to determine the optimal dispatcher-assisted CPR (DA-CPR) instructions for OHCA. Methods We analysed the records of 24,947 adult patients (aged ≥ 18 years) who received bystander DA-CPR after bystander-witnessed OHCA. Data were obtained from a prospectively recorded Japanese nationwide Utstein-style database for a 2-year period (2016–2017). Patients were divided into compression-only DA-CPR (n = 22,778) and conventional DA-CPR (with a compression-to-ventilation ratio of 30:2, n = 2169) groups. The primary outcome measure was 1-month neurological intact survival, defined as a cerebral performance category score of 1–2 (CPC 1–2). Results The 1-month CPC 1–2 rate was significantly higher in the conventional DA-CPR group than in the compression-only DA-CPR group (before propensity score (PS) matching, 7.5% [162/2169] versus 5.8% [1309/22778], p < 0.01; after PS matching, 7.5% (162/2169) versus 5.7% (123/2169), p < 0.05). Compared with compression-only DA-CPR, conventional DA-CPR was associated with increased odds of 1-month CPC 1–2 (before PS matching, adjusted odds ratio 1.39, 95% confidence interval [CI] 1.14–1.70, p < 0.01; after PS matching, adjusted odds ratio 1.34, 95% CI 1.00–1.79, p < 0.05). Conclusion Within the limitations of this retrospective observational study, conventional DA-CPR with a compression-to-ventilation ratio of 30:2 was preferable to compression-only DA-CPR as an optimal DA-CPR instruction for coaching callers to perform bystander CPR for adult patients with bystander-witnessed OHCAs.

Introduction: Lay rescuers have a crucial role in successful cardiopulmonary resuscitation (CPR), specifically the first three links in the chain of survival, for out-of-hospital cardiac arrest (OHCA). However, randomized controlled trials on the priority of emergency call (Call first) versus bystander CPR (CPR first) do not exist, and comparative data are very limited. We aimed to assess the association between the priority of bystander’s action (Call first vs. CPR first) and neurologic outcome after OHCA. Methods: This nationwide population-based study of patients who experienced OHCA from January 2005 to December 2014 was based on the data from the Japanese government-managed registry of OHCA. Patients provided bystander’s action (both emergency call and bystander CPR) within 1 minute of witness were included, and Call first strategy was compared with CPR first strategy. The primary outcome was one-month neurologically favorable survival, defined as a Glasgow-Pittsburgh cerebral performance category (CPC) score of 1(good performance) or 2(moderate disability). The secondary outcomes were prehospital return of spontaneous circulation (ROSC) and one-month overall survival. Results: A total of 25,840 patients were included; 4,430 (17.1%) were treated with Call first approach, and 21,410 (82.9%) were treated with CPR first approach. Among total cohort, 2,696 (10.4%) survived with neurologically favorable status one month after OHCA. In the propensity score-matched cohort, one-month neurologically favorable survival was lower among Call first group compared with CPR first group: 364 of 4,430 patients (8.2%) vs. 457 of 4,430 patients (10.3%), respectively (Risk ratio [RR], 0.80; 95% confidence interval [CI], 0.70-0.91). Similar associations were observed for one-month overall survival (RR, 0.90; 95%CI, 0.82-0.99), although there were no significant differences in prehospital ROSC (RR, 0.94; 95%CI, 0.86-1.02) between the Call first and CPR first groups. In subgroup analyses, the association between delayed bystander CPR and worse neurological outcome did not change regardless of subgroup characteristics. Conclusions: In witnessed OHCA, Call first approach was associated with a decreased chance of one-month neurologically favorable survival compared with CPR first approach. These observational findings warrant a randomized clinical trial to determine the priority of emergency call or bystander CPR for OHCA.

The Impact

<b><i>Introduction:</i></b> Very little is known about the impact of vision impairment (VI) on physical health in late-life in sub-Saharan Africa populations, whereas many older people experience it. We investigated the association between self-reported VI and frailty in Central African older people with low cognitive performance. <b><i>Methods:</i></b> It was cross-sectional analysis of data from the Epidemiology of Dementia in Central Africa (EPIDEMCA) population-based study. After screening for cognitive impairment, older people with low cognitive performance were selected. Frailty was assessed using the Study of Osteoporotic Fracture index. Participants who met one of the 3 parameters assessed (unintentional weight loss, inability to do 5 chair stands, and low energy level) were considered as pre-frail, and those who met 2 or more parameters were considered as frail. VI was self-reported. Associations were investigated using multinomial logistic regression models. <b><i>Results:</i></b> Out of 2,002 older people enrolled in EPIDEMCA, 775 (38.7%) had low cognitive performance on the screening test. Of them, 514 participants (sex ratio: 0.25) had available data on VI and frailty and were included in the analyses. In total, 360 (70%) self-reported VI. Prevalence of frailty was estimated at 64.9% [95% confidence interval: 60.9%–69.1%] and 23.7% [95% CI: 20.1%–27.4%] for pre-frailty. After full adjustment, self-reported VI was associated with frailty (adjusted odds ratio = 2.2; 95% CI: 1.1–4.3) but not with pre-frailty (adjusted odds ratio = 1.8; 95% CI: 0.9–3.7). <b><i>Conclusion:</i></b> In Central African older people with low cognitive performance, those who self-reported VI were more likely to experience frailty. Our findings suggest that greater attention should be devoted to VI among this vulnerable population in order to identify early frailty onset and provide adequate care management.

Therapeutic hypothermia is beneficial to neurological outcome for comatose survivors after out-of-hospital cardiac arrest. However, there are few data of extracorporeal cardiopulmonary resuscitation (ECPR) for induction of hypothermia for patients with out-of-hospital cardiac arrest. We did a prospective study of ECPR with hypothermia for patients with out-of-hospital cardiac arrest. The criteria for inclusion were an age of 18 to 74 years, a witnessed cardiac arrest, collapse-to-patient’s-side interval <15 minutes, cardiac arrest due to presumed cardiac etiology, and persistent cardiac arrest on ER arrival in spite of the prehospital defibrillations. After arrival at the emergency room, cardiopulmonary bypass plus intra-aortic balloon pumping was immediately performed, and then coronary reperfusion therapy during cardiac arrest was added if needed. Mild hypothermia (34°C for 3 days) was immediately induced during cardiac arrest or after return of spontaneous circulation. We selected suitable patients who received conventional CPR with normothermia among a prospective multi-center observational study of patients who had out-of-hospital cardiac arrest in Kanto region of Japan “the SOS-KANTO study” for the control group. The primary endpoint was favorable neurological outcome at the time of hospital discharge. A total of 558 patients were enrolled; 127 received ECPR with hypothermia and 431 received conventional CPR with normothermia. The ECPR with hypothermia group had significantly higher frequency of the favorable neurological outcome than the conventional CPR with normothermia group (12% vs. 2%, unadjusted odds ratio, 8.1; 95% CI; 3.2 to 20.0). The adjusted odds ratio for the favorable neurological outcome after ECPR with hypothermia was 7.4 (95% CI; 2.8 to 19.3, p<0.0001). Among the ECPR with hypothermia group, early attainment of a target core temperature of 34°C increased its efficacy (adjusted odds ratio, 0.99; 95% CI; 0.98 to 1.00, p=0.04). ECPR with hypothermia improved the chance of neurologically intact survival for adult patients with out-of-hospital cardiac arrest, and the early attainment of a target temperature enhanced its efficacy.

Background: Dissemination of the Physical Activity Guidelines for Americans (Guidelines) is needed, but how individuals respond to the Guidelines is not well understood. This surveillance study describes US adults’ reported responses to and information sources for hearing about the Guidelines and explores relationships between how respondents heard about the Guidelines and their reported response(s). Methods: Data were analyzed from the population-based 2019 Health Information National Trends Survey 5 Cycle 3. Population-weighted proportions of response were calculated. Among those who had heard about the Guidelines, binary logistic regressions examined associations between the reported response(s) and the information source and number of sources reported. Results: The analytical sample included 5047 adults. Nearly 65% of US adults reported hearing about the Guidelines, and 29% reported a behavioral response (eg, increased physical activity). Hearing about the Guidelines through health professionals (adjusted odds ratio = 2.30, 95% confidence interval, 1.45–3.65) or social media (adjusted odds ratio = 1.89, 95% confidence interval, 1.20–2.96) (vs other sources) was associated with reporting increasing physical activity. Hearing from multiple sources (vs one source) was associated with reporting increasing physical activity (adjusted odds ratio = 1.97, 95% confidence interval, 1.18–3.31). Conclusion: Findings suggest dissemination of the Guidelines across multiple channels may promote greater changes in physical activity.

BackgroundSafety-netting advice is information shared with a patient or their carer designed to help them identify the need to seek further medical help if their condition fails to improve, changes, or if they have concerns about their health.AimTo assess when and how safety-netting advice is delivered in routine GP consultations.Design and settingThis was an observational study using 318 recorded GP consultations with adult patients in the UK.MethodA safety-netting coding tool was applied to all consultations. Logistic regression for the presence or absence of safety-netting advice was compared between patient, clinician, and problem variables.ResultsA total of 390 episodes of safety-netting advice were observed in 205/318 (64.5%) consultations for 257/555 (46.3%) problems. Most advice was initiated by the GP (94.9%) and delivered in the treatment planning (52.1%) or closing (31.5%) consultation phases. Specific advice was delivered in almost half (47.2%) of episodes. Safety-netting advice was more likely to be present for problems that were acute (odds ratio [OR] 2.18, 95% confidence interval [CI] = 1.30 to 3.64), assessed first in the consultation (OR 2.94, 95% CI = 1.85 to 4.68) or assessed by GPs aged ≤49 years (OR 2.56, 95% CI = 1.45 to 4.51). Safety-netting advice was documented for only 109/242 (45.0%) problems.ConclusionGPs appear to commonly give safety-netting advice, but the contingencies or actions required on the patient’s part may not always be specific or documented. The likelihood of safety-netting advice being delivered may vary according to characteristics of the problem or the GP. How to assess safety-netting outcomes in terms of patient benefits and harms does warrant further exploration.

Abstract Editor’s Perspective What We Already Know about This Topic What This Article Tells Us That Is New Background Because the extent to which delays in initiating cardiopulmonary resuscitation (CPR) versus the time from CPR to defibrillation or epinephrine treatment affects survival remains unknown, it was hypothesized that all three independently decrease survival in in-hospital cardiac arrest. Methods Witnessed, index cases of cardiac arrest from the Get With The Guidelines–Resuscitation Database occurring between 2000 and 2008 in 538 hospitals were included in this analysis. Multivariable risk-adjusted logistic regression examined the association of time to initiation of CPR and time from CPR to either epinephrine treatment or defibrillation with survival to discharge. Results In the overall cohort of 57,312 patients, there were 9,802 survivors (17.1%). Times to initiation of CPR greater than 2 min were associated with a survival of 14.7% (91 of 618) as compared with 17.1% (9,711 of 56,694) if CPR was begun in 2 min or less (adjusted odds ratio [95% CI], 0.68 [0.54 to 0.87]; P &lt; 0.002). Times from CPR to either defibrillation or epinephrine treatment of 2 min or less were associated with a survival of 18.0% (7,654 of 42,475), as compared with 15.0% (1,680 of 11,227) for 3 to 5 min (reference, 0 to 2 min; adjusted odds ratios [95% CI], 0.83 [0.78 to 0.88]; P &lt; 0.001), 12.8% (382 of 2,983) for 6 to 8 min (0.67 [0.60 to 0.76], P &lt; 0.001), and 13.7% (86 of 627) for 9 to 11 min (0.54 [0.42 to 0.69], P &lt; 0.001). Conclusions Delays in the initiation of CPR and from CPR to defibrillation or epinephrine treatment were each associated with lower survival.

AbstractObjectivesTo evaluate the association between experience in the management of acute pulmonary embolism, reflected by hospital case volume, and mortality.DesignMultinational population based cohort study using data from the Registro Informatizado de la Enfermedad TromboEmbólica (RIETE) registry between 1 January 2001 and 31 August 2018.Setting353 hospitals in 16 countries.Participants39 257 consecutive patients with confirmed diagnosis of acute symptomatic pulmonary embolism.Main outcome measurePulmonary embolism related mortality within 30 days after diagnosis of the condition.ResultsPatients with acute symptomatic pulmonary embolism admitted to high volume hospitals (>40 pulmonary embolisms per year) had a higher burden of comorbidities. A significant inverse association was seen between annual hospital volume and pulmonary embolism related mortality. Admission to hospitals in the highest quarter (that is, >40 pulmonary embolisms per year) was associated with a 44% reduction in the adjusted odds of pulmonary embolism related mortality at 30 days compared with admission to hospitals in the lowest quarter (<15 pulmonary embolisms per year; adjusted risk 1.3% v 2.3%; adjusted odds ratio 0.56 (95% confidence interval 0.33 to 0.95); P=0.03). Results were consistent in all sensitivity analyses. All cause mortality at 30 days was not significantly reduced between the two quarters (adjusted odds ratio 0.78 (0.50 to 1.22); P=0.28). Survivors showed little change in the odds of recurrent venous thromboembolism (odds ratio 0.76 (0.49 to 1.19)) or major bleeding (1.07 (0.77 to 1.47)) between the low and high volume hospitals.ConclusionsIn patients with acute symptomatic pulmonary embolism, admission to high volume hospitals was associated with significant reductions in adjusted pulmonary embolism related mortality at 30 days. These findings could have implications for management strategies.

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.

Aims: To assess the long-term outcome of childhood tuberculous meningitis treated with modern 4-drug antitubercular regimens and to determine predictors of survival and morbidity. Methods: In this single-center prospective cohort, outcome of children with tuberculous meningitis treated with standard regimens was assessed at 6 months and 12 months after discharge using the Pediatric Cerebral Performance Category Scale. Results: Of 130 children, 38 died in hospital and 34 were either severely disabled or comatose/vegetative at discharge. At 6 and 12 months, 87% of the survivors were either normal (n = 62) or mildly disabled (n = 17, on the Pediatric Cerebral Performance Category scale). On multivariate analysis, the factors associated with poor outcome at 12 months were stage III at admission (adjusted odds ratio 4.4, 95% confidence interval, 1.7-11.2, P = .002) and presence of infarcts on neuroimaging (adjusted odds ratio 2.6, 95% confidence interval, 1.1-6.6, P = .037). Conclusions: Despite the high in-hospital mortality, in resource-constraint settings, the survivors showed remarkable improvement, with two-thirds returning to a normal functional status at 6 months’ follow-up.
