RESUMO
BACKGROUND: Bystander cardiopulmonary resuscitation (CPR) is associated with higher survival for out-of-hospital cardiac arrest, but whether its association with survival differs by patients' sex and race and ethnicity is less clear. METHODS: Within a large US registry, we identified 623 342 nontraumatic out-of-hospital cardiac arrests during 2013 to 2022 for this observational cohort study. Using hierarchical logistic regression, we examined whether there was a differential association between bystander CPR and survival outcomes by patients' sex and race and ethnicity, overall and by neighborhood strata. RESULTS: Mean age was 62.1±17.1 years, and 35.9% were women. Nearly half of patients (49.8%) were non-Hispanic White; 20.6% were non-Hispanic Black; 7.3% were Hispanic; 2.9% were Asian; and 0.4% were Native American. Overall, 58 098 (9.3%) survived to hospital discharge. Although bystander CPR was associated with higher survival in each race and ethnicity group, the association of bystander CPR compared with patients without bystander CPR in each racial and ethnic group was highest in individuals who were White (adjusted odds ratio [OR], 1.33 [95% CI, 1.30-1.37]) and Native American (adjusted OR, 1.40 [95% CI, 1.02-1.90]) and lowest in individuals who were Black (adjusted OR, 1.09 [95% CI, 1.04-1.14]; Pinteraction<0.001). The adjusted OR for bystander CPR compared with those without bystander CPR for Hispanic patients was 1.29 (95% CI, 1.20-1.139), for Asian patients, it was 1.27 (95% CI, 1.12-1.42), and for those of unknown race, it was 1.31 (95% CI, 1.25-1.36). Similarly, bystander CPR was associated with higher survival in both sexes, but its association with survival was higher in men (adjusted OR, 1.35 [95% CI, 1.31-1.38]) than women (adjusted OR, 1.15 [95% CI, 1.12-1.19]; Pinteraction<0.001). The weaker association of bystander CPR in Black individuals and women was consistent across neighborhood race and ethnicity and income strata. Similar results were observed for the outcome of survival without severe neurological deficits. CONCLUSIONS: Although bystander CPR was associated with higher survival in all patients, its association with survival was weakest for Black individuals and women with out-of-hospital cardiac arrest.

BACKGROUND: Survival for in-hospital cardiac arrest (IHCA) has declined since the COVID-19 pandemic. Because the burden of COVID-19 was uneven throughout the U.S., it remains unknown if top-performer hospitals in IHCA survival have remained top-performers since the pandemic. METHODS: Within Get With The Guidelines®-Resuscitation, we identified hospitals with at least 2 years of registry participation pre-pandemic (2017-2019) and post-pandemic (July 2020-2022) and with at least 20 IHCA cases in both periods. Using multivariable hierarchical models with hospital as a random effect and adjusting for patient and arrest characteristics, we calculated risk-standardized survival rates to discharge (RSSR) for IHCA at each hospital during the pre- and post-pandemic periods. We then assessed the correlation between a hospital's pre-pandemic and post-pandemic RSSR for IHCA, and whether the correlation differed by the proportion of Black or Hispanic IHCA patients at each hospital. RESULTS: A total of 243 hospitals were included, comprising 122,561 IHCAs (pre-pandemic: 57,601; post-pandemic: 64,960). Pre-pandemic, the mean RSSR was 26.8% (SD, 5.2%) whereas the mean RSSR post-pandemic was 21.7% (SD, 5.5%). There was good correlation between a hospital's pre- and post-pandemic RSSR: correlation of 0.55. When hospitals were categorized into tertiles based on the proportion of their IHCA patients who were Black or Hispanic, this correlation remained similar: 0.48, 0.68, and 0.45 (interaction P-value: 0.69) for hospitals in the upper, middle and lower tertiles, respectively. CONCLUSION: Although the COVID-19 pandemic affected the U.S. unevenly, there was good correlation in a hospital's performance for IHCA survival before and after the pandemic, even at hospitals caring for a larger proportion of Black and Hispanic patients. Future studies are needed to understand what characteristics of high-performing hospitals pre-pandemic allowed many to continue to excel in the post-pandemic period.
RESUMO
Importance: Cardiopulmonary resuscitation (CPR) duration is associated with cardiac arrest survival. Objectives: To describe characteristics associated with CPR duration among hospitalized children without return of circulation (ROC) (patient-level analysis) and determine whether hospital median CPR duration in patients without ROC is associated with survival (hospital-level analysis). Design, Setting, and Participants: This retrospective cohort study of patients undergoing pediatric in-hospital CPR between January 1, 2000, and December 31, 2021, used data from the Get With the Guidelines-Resuscitation registry. Children receiving chest compressions for at least 2 minutes and/or defibrillation were included in the patient-level analysis. For the hospital-level analysis, sites with at least 20 total events and at least 5 events without ROC were included. Data were analyzed from December 1, 2022, to November 15, 2023. Exposures: For the patient-level analysis, the exposure was CPR duration in patients without ROC. For the hospital-level analysis, the exposure was quartile of median CPR duration in events without ROC at each hospital. Main Outcomes and Measures: For the patient-level analysis, outcomes were patient and event factors, including race and ethnicity and event location; we used a multivariable hierarchical linear regression model to assess factors associated with CPR duration in patients without ROC. For the hospital-level analysis, the main outcome was survival to discharge among all site events; we used a random intercept multivariable hierarchical logistic regression model to examine the association between hospital quartile of CPR duration and survival to discharge. Results: Of 13â¯899 events, 3859 patients did not have ROC (median age, 7 months [IQR, 0 months to 7 years]; 2175 boys [56%]). Among event nonsurvivors, median CPR duration was longer in those with initial rhythms of bradycardia with poor perfusion (8.37 [95% CI, 5.70-11.03] minutes; P < .001), pulseless electrical activity (8.22 [95% CI, 5.44-11.00] minutes; P < .001), and pulseless ventricular tachycardia (6.17 [95% CI, 0.09-12.26] minutes; P = .047) (vs asystole). Shorter median CPR duration was associated with neonates compared with older children (-4.86 [95% CI, -8.88 to -0.84] minutes; P = .02), emergency department compared with pediatric intensive car7 e unit location (-4.02 [95% CI, -7.48 to -0.57] minutes; P = .02), and members of racial or ethnic minority groups compared with White patients (-3.67 [95% CI, -6.18 to -1.17]; P = .004). Among all CPR events, the adjusted odds of survival to discharge differed based on hospital quartile of median CPR duration among events without ROC; compared with quartile 1 (15.0-25.9 minutes), the adjusted odds ratio for quartile 2 (26.0-29.4 minutes) was 1.22 (95% CI, 1.09-1.36; P < .001); for quartile 3 (29.5-32.9 minutes), 1.23 (95% CI, 1.08-1.39; P = .002); and for quartile 4 (33.0-53.0 minutes), 1.04 (95% CI, 0.91-1.19; P = .58). Conclusions and Relevance: In this retrospective cohort study of pediatric in-hospital CPR, several factors, including age and event location, were associated with CPR duration in event nonsurvivors. The odds of survival to discharge were lower for patients at hospitals with the shortest and longest median CPR durations among events without ROC. Further studies are needed to determine the optimal duration of CPR during pediatric in-hospital cardiac arrest and to provide training guidelines for resuscitation teams to eliminate disparities in resuscitation care.

Background: How frequently out-of-hospital cardiac arrest (OHCA) occurs within a reasonable walking distance to the nearest public automated external defibrillator (AED) has not been well studied. Methods: As Kansas City, Missouri has a comprehensive city-wide public AED registry, we identified adults with an OHCA in Kansas City during 2019-2022 in the Cardiac Arrest Registry to Enhance Survival. Using AED location data from the registry, we computed walking times between OHCAs and the nearest registered AED using the Haversine formula, a mapping algorithm to calculate walking distance in miles from one location to another. Results were stratified by OHCA location (home vs. public) and by whether the patient received bystander cardiopulmonary resuscitation (CPR). Results: Of 1,522 OHCAs, 1,291 (84.8%) occurred at home and 231 (15.2%) in public. Among at-home OHCAs, 634 (49.1%) received bystander CPR and no patients had an AED applied even as 297 (23.0%) were within a 4-minute walk to the closest public AED. Among OHCAs in public, 108 (46.8%) were within a 4-minute walk to the closest public AED. For public OHCAs within a 4-minute walk, bystanders applied an AED in 13 (12.0%) of these cases and in 24.5% (13/53) of those who received bystander CPR. Conclusion: In one U.S. city with a publicly available AED registry, there were no instances in which a bystander accessed a public AED for an OHCA at home. For OHCAs in public, nearly half occurred within a 4-minute walk to the closest AED but bystander use of an AED was low.
RESUMO
AIM: Given challenges in collecting long-term outcomes for survivors of in-hospital cardiac arrest (IHCA), most studies have focused on in-hospital survival. We evaluated the correlation between a hospital's risk-standardized survival rate (RSSR) at hospital discharge for IHCA with its RSSR for long-term survival. METHODS: We identified patients ≥65 years of age with IHCA at 472 hospitals in Get With The Guidelines®-Resuscitation registry during 2000-2012, who could be linked to Medicare files to obtain post-discharge survival data. We constructed hierarchical logistic regression models to compute RSSR at discharge, and 30-day, 1-year, and 3-year RSSRs for each hospital. The association between in-hospital and long-term RSSR was evaluated with weighted Kappa coefficients. RESULTS: Among 56,231 Medicare beneficiaries (age 77.2 ± 7.5 years and 25,206 [44.8%] women), 10,536 (18.7%) survived to discharge and 8,485 (15.1%) survived to 30 days after discharge. Median in-hospital, 30-day, 1-year, and 3-year RSSRs were 18.6% (IQR, 16.7-20.4%), 14.9% (13.2-16.7%), 10.3% (9.1-12.1%), and 7.6% (6.8-8.8%), respectively. The weighted Kappa coefficient for the association between a hospital's RSSR at discharge with its 30-day, 1-year, and 3-year RSSRs were 0.72 (95% CI, 0.68-0.76), 0.56 (0.50-0.61), and 0.47 (0.41-0.53), respectively. CONCLUSIONS: There was a strong correlation between a hospital's RSSR at discharge and its 30-day RSSR for IHCA, although this correlation weakens over time. Our findings suggest that a hospital's RSSR at discharge for IHCA may be a reasonable surrogate of its 30-day post-discharge survival and could be used by Medicare to benchmark hospital performance for this condition without collecting 30-day survival data.
RESUMO
Importance: Survival for out-of-hospital cardiac arrest (OHCA) varies widely across emergency medical service (EMS) agencies in the US. However, little is known about which EMS practices are associated with higher agency-level survival. Objective: To identify resuscitation practices associated with favorable neurological survival for OHCA at EMS agencies. Design, Setting, and Participants: This cohort study surveyed EMS agencies participating in the Cardiac Arrest Registry to Enhance Survival (CARES) with 10 or more OHCAs annually during January 2015 to December 2019; data analyses were performed from April to October 2023. Exposure: Survey of resuscitation practices at EMS agencies. Main Outcomes and Measures: Risk-standardized rates of favorable neurological survival for OHCA at each EMS agency were estimated using hierarchical logistic regression. Multivariable linear regression then examined the association of EMS practices with rates of risk-standardized favorable neurological survival. Results: Of 577 eligible EMS agencies, 470 agencies (81.5%) completed the survey. The mean (SD) rate of risk-standardized favorable neurological survival was 8.1% (1.8%). A total of 7 EMS practices across 3 domains (training, cardiopulmonary resuscitation [CPR], and transport) were associated with higher rates of risk-standardized favorable neurological survival. EMS agencies with higher favorable neurological survival rates were more likely to use simulation to assess CPR competency (ß = 0.54; P = .05), perform frequent reassessment (at least once every 6 months) of CPR competency in new staff (ß = 0.51; P = .04), use full multiperson scenario simulation for ongoing skills training (ß = 0.48; P = .01), perform simulation training at least every 6 months (ß = 0.63; P < .001), and conduct training in the use of mechanical CPR devices at least once annually (ß = 0.43; P = .04). EMS agencies with higher risk-standardized favorable neurological survival were also more likely to use CPR feedback devices (ß = 0.58; P = .007) and to transport patients to a designated cardiac arrest or ST-segment elevation myocardial infarction receiving center (ß = 0.57; P = .003). Adoption of more than half (≥4) of the 7 practices was more common at EMS agencies in the highest quartile of favorable neurological survival rates (70 of 118 agencies [59.3%]) vs the lowest quartile (42 of 118 agencies [35.6%]) (P < .001). Conclusions and Relevance: In a national registry for OHCA, 7 practices associated with higher rates of favorable neurological survival were identified at EMS agencies. Given wide variability in neurological survival across EMS agencies, these findings provide initial insights into EMS practices associated with top-performing EMS agencies in OHCA survival. Future studies are needed to validate these findings and identify best practices for EMS agencies.

BACKGROUND: Quantifying guideline-directed medical therapy (GDMT) intensity is foundational for improving heart failure (HF) care. Existing measures discount dose intensity or use inconsistent weighting. METHODS: The Kansas City Medical Optimization (KCMO) score is the average of total daily to target dose percentages for eligible GDMT, reflecting the percentage of optimal GDMT prescribed (range, 0-100). In Change the Management of Patients With HF, we computed KCMO, HF collaboratory (0-7), and modified HF Collaboratory (0-100) scores for each patient at baseline and for 1-year change in established GDMT at the time (mineralocorticoid receptor antagonist, ß-blocker, ACE [angiotensin-converting enzyme] inhibitor/angiotensin receptor blocker/angiotensin receptor neprilysin inhibitor). We compared baseline and 1-year change distributions and the coefficient of variation (SD/mean) across scores. RESULTS: Among 4532 patients at baseline, mean KCMO, HF collaboratory, and modified HF Collaboratory scores were 38.8 (SD, 25.7), 3.4 (1.7), and 42.2 (22.2), respectively. The mean 1-year change (n=4061) for KCMO was -1.94 (17.8); HF collaborator, -0.11 (1.32); and modified HF Collaboratory, -1.35 (19.8). KCMO had the highest coefficient of variation (0.66), indicating greater variability around the mean than the HF collaboratory (0.49) and modified HF Collaboratory (0.53) scores, reflecting higher resolution of the variability in GDMT intensity across patients. CONCLUSIONS: KCMO measures GDMT intensity by incorporating dosing and treatment eligibility, provides more granularity than existing methods, is easily interpretable (percentage of ideal GDMT), and can be adapted as performance measures evolve. Further study of its association with outcomes and its usefulness for quality assessment and improvement is needed.

BACKGROUND: Cardiac arrest is 1 of the leading causes of morbidity and mortality, with an estimated 340 000 out-of-hospital and 292 000 in-hospital cardiac arrest events per year in the United States. Survival rates are lower in certain racial and socioeconomic groups. METHODS AND RESULTS: We performed a county-level cross-sectional longitudinal study using the Centers for Disease Control and Prevention's Wide-Ranging Online Data for Epidemiologic Research multiple causes of death data set between 2016 and 2020 among individuals of all ages whose death was attributed to cardiac arrest. The Social Vulnerability Index is a composite measure that includes socioeconomic vulnerability, household composition, disability, individuals from racial and ethnic minority groups status and language, and housing and transportation domains. We examined the impact of social determinants on cardiac arrest mortality stratified by age, race, ethnicity, and sex in the United States. All age-adjusted mortality rate (cardiac arrest AAMRs) are reported as per 100 000. Overall cardiac arrest AAMR during the study period was 95.6. The cardiac arrest AAMR was higher for men compared with women (119.6 versus 89.9) and for the Black population compared with the White population (150.4 versus 92.3). The cardiac arrest AAMR increased from 64.8 in counties in quintile 1 of Social Vulnerability Index to 141 in quintile 5, with an average increase of 13% (95% CI, 9.8%-16.9%) in AAMR per quintile increase. CONCLUSIONS: Mortality from cardiac arrest varies widely, with a >2-fold difference between the counties with the highest and lowest social vulnerability, highlighting the differential burden of cardiac arrest deaths throughout the United States based on social determinants of health.

Cardiac arrest is common and associated with significant mortality and morbidity among survivors. To better understand the epidemiology and outcomes of cardiac arrest, many countries and regions have developed cardiac arrest registries. In the United States, with the diversity of its population, these registries have illuminated differences and disparities in the care and outcomes of cardiac arrest patients based on their race, ethnicity, and sex. These findings raise concerns as traditionally vulnerable patient groups have lower survival rates for cardiac arrest-a condition for which overall survival is already low. Although leveraging registries to raise awareness of disparities in cardiac arrest outcomes is an important first step, further research is needed to understand the sources of these differences, narrow observed disparities and improve overall outcomes.

OBJECTIVES: Contrary to advanced cardiac life support guidelines that recommend immediate defibrillation for shockable in-hospital cardiac arrest (IHCA), epinephrine administration before first defibrillation is common and associated with lower survival at a "patient-level." Whether this practice varies across hospitals and its association with "hospital-level" IHCA survival remains unknown. The purpose of this study was to determine hospital variation in rates of epinephrine administration before defibrillation for shockable IHCA and its association with IHCA survival. DESIGN: Observational cohort study. SETTING: Five hundred thirteen hospitals participating in the Get With The Guidelines Resuscitation Registry. PATIENTS: A total of 37,668 adult patients with IHCA due to an initial shockable rhythm from 2000 to 2019. INTERVENTIONS: Epinephrine before first defibrillation. MEASUREMENTS AND MAIN RESULTS: Using multivariable hierarchical regression, we examined hospital variation in epinephrine administration before first defibrillation and its association with hospital-level rates of risk-adjusted survival. The median hospital rate of epinephrine administration before defibrillation was 18.8%, with large variation across sites (range, 0-68.8%; median odds ratio: 1.54; 95% CI, 1.47-1.61). Major teaching status and annual IHCA volume were associated with hospital rate of epinephrine administration before defibrillation. Compared with hospitals with the lowest rate of epinephrine administration before defibrillation (Q1), there was a stepwise decline in risk-adjusted survival at hospitals with higher rates of epinephrine administration before defibrillation (Q1: 44.3%, Q2: 43.4%; Q3: 41.9%; Q4: 40.3%; p for trend < 0.001). CONCLUSIONS: Administration of epinephrine before defibrillation in shockable IHCA is common and varies markedly across U.S. hospitals. Hospital rates of epinephrine administration before defibrillation were associated with a significant stepwise decrease in hospital rates of risk-adjusted survival. Efforts to prioritize immediate defibrillation for patients with shockable IHCA and avoid early epinephrine administration are urgently needed.

BACKGROUND: It is unclear how the type of an atherosclerotic cardiovascular disease (ASCVD) event potentially influences patients' likelihood of smoking cessation. METHODS: Using 2013 to 2018 data from the US based National Cardiovascular Data Registry Practice Innovation and Clinical Excellence outpatient cardiac registry, we identified patients who were current smokers at a clinic visit and followed them over time for a subsequent ASCVD event. Self-reported smoking status was assessed at each consecutive visit and used to determine smoking cessation after each interim ASCVD event (myocardial infarction, percutaneous coronary intervention, coronary artery bypass graft, stroke/transient ischemic attack, peripheral artery disease). We constructed separate multivariable Cox models with nonproportional hazards to examine the association of each interim ASCVD event with smoking cessation, compared with not having an interim ASCVD event. We estimated the relative association of ASCVD event type with smoking cessation using contrast tests. Analyses were stratified by presence versus absence of ASCVD at baseline. RESULTS: Across 530 cardiology practices, we identified 1 933 283 current smokers (mean age 62±15, male 54%, ASCVD at baseline 50%). Among the 322 743 patients who had an interim ASCVD event and were still smoking, 41 336 (12.8%) quit smoking by their first subsequent clinic visit, which was higher among those with baseline ASCVD (13.4%) as compared with those without baseline ASCVD (11.5%). Each type of ASCVD event was associated with an increased likelihood of smoking. Patients who had an myocardial infarction, underwent coronary artery bypass graft (hazard ratio, 1.60 [95% CI, 1.55-1.65]), or had a stroke or transient ischemic attack were more likely to quit smoking as compared with those who underwent elective percutaneous coronary intervention or had a new diagnosis of peripheral artery disease (hazard ratio, 1.20 [95% CI, 1.17-1.22]). CONCLUSIONS: Only 13% of patients reported smoking cessation after an ASCVD event, with the type of event being associated with the likelihood of smoking cessation, prompting the need for patient-centered interventions.

Importance: A primary objective in managing atrial fibrillation (AF) is to optimize patients' health status, which can be done only if physicians accurately quantify the outcomes associated with AF in patients' lives. Objective: To explore physicians' estimation of the health status of patients with AF and its association with subsequent care and outcomes. Design, Setting, and Participants: A multicenter, prospective cohort study was conducted in 2 outpatient practices in Tokyo, Japan. Participants included patients with newly diagnosed AF or those referred for initial treatment of AF at outpatient practices and treating physicians from November 8, 2018, to April 1, 2020. Data analysis was performed from December 22, 2022, to July 7, 2023. Exposures: Participating patients completed the Atrial Fibrillation Effect on Quality-of-Life (AFEQT) questionnaire, a 20-item tool covering 4 domains with a 7-point Likert scale; 3 domains (symptoms, daily activities, and treatment concerns) were used in this study. Blinded to patients' responses, treating physicians answered a 3-item questionnaire quantifying each patient's AFEQT domain with a single item. Patients' mean Likert scale responses within each AFEQT domain were subtracted from the physicians' assessments so that higher scores (≥0.5 points) indicate physician underestimation, while lower scores (≤0.5 points) indicate physician overestimation of the health status of patients with AF. Main Outcomes and Measures: The independent association of physician-patient concordance with treatment escalation (alteration or initiation of antiarrhythmic drugs, cardioversion, or catheter ablation) and 1-year adjusted changes in AFEQT scores. Results: Among 330 patients (238 [72.1%] men; mean [SD] age, 67.9 [11.9] years; 163 [49.4%] with paroxysmal AF), physicians correctly estimated health status in 112 patients (33.9%), underestimated it in 42 patients (12.7%), and overestimated it in 176 patients (53.3%). Treatment escalation occurred in 63.6% of patients whose health status was correctly estimated, 47.6% of those whose health status was underestimated, and 66.3% of patients whose health status was overestimated. After multivariable adjustment, underestimation of health status was independently associated with less treatment escalation (adjusted odds ratio, 0.43; 95% CI, 0.20-0.90) and less frequent AFEQT overall summary score improvement at 1 year (underestimated, 2.5 [95% CI, -1.6 to 6.7] vs correctly and overestimated health status, 8.4 [95% CI, 7.0-9.9] points; P = .01). Conclusions and Relevance: In this cohort study, physician underestimation of the health status of patients with AF was common and associated with less aggressive treatment and less health status improvement at 1 year.

Every 10 years, the American Heart Association (AHA) Emergency Cardiovascular Care Committee establishes goals to improve survival from cardiac arrest. These goals align with broader AHA Impact Goals and support the AHA's advocacy efforts and strategic investments in research, education, clinical care, and quality improvement programs. This scientific statement focuses on 2030 AHA emergency cardiovascular care priorities, with a specific focus on bystander cardiopulmonary resuscitation, early defibrillation, and neurologically intact survival. This scientific statement also includes aspirational goals, such as establishing cardiac arrest as a reportable disease and mandating reporting of standardized outcomes from different sources; advancing recognition of and knowledge about cardiac arrest; improving dispatch system response, availability, and access to resuscitation training in multiple settings and at multiple time points; improving availability, access, and affordability of defibrillators; providing a focus on early defibrillation, in-hospital programs, and establishing champions for debriefing and review of cardiac arrest events; and expanding measures to track outcomes beyond survival. The ability to track and report data from these broader aspirational targets will potentially require expansion of existing data sets, development of new data sets, and enhanced integration of technology to collect process and outcome data, as well as partnerships of the AHA with national, state, and local organizations. The COVID-19 (coronavirus disease 2019) pandemic, disparities in COVID-19 outcomes for historically excluded racial and ethnic groups, and the longstanding disparities in cardiac arrest treatment and outcomes for Black and Hispanic or Latino populations also contributed to an explicit focus and target on equity for the AHA Emergency Cardiovascular Care 2030 Impact Goals.

BACKGROUND: Delays in bystander cardiopulmonary resuscitation (CPR) are associated with worse out-of-hospital cardiac arrest (OHCA) outcomes. Whether disparities exist in time to CPR between women and men is unknown. METHODS: We included witnessed OHCAs treated with bystander CPR from the Cardiac Arrest Registry Enhancing Survival between 2013-2021. The primary outcome was time to first bystander CPR, and secondary outcomes were survival to hospital discharge and favorable neurological survival. Hierarchical ordinal regression was used to model time to first CPR, which estimates the odds of having a 2-minute longer delay (from 0 to ≥10 minutes) in receiving bystander CPR. The model included sex, age, race, location of arrest, cardiac arrest etiology, day of week, and season as fixed effects and EMS agency as a random effect to account for clustering of patients within an agency. RESULTS: Of 78,043 patients with a witnessed OHCA that received bystander CPR, 25,197 (32.3%) were women. The median [IQR] time to first bystander CPR was 2 [1,5] minutes for both women and men. In adjusted analysis, time to bystander CPR was similar in men and women (p = 0.26). Moreover, there was a statistically significantly graded inverse association between time to bystander CPR and survival. CONCLUSION: For patients with witnessed OHCA that received bystander CPR, women and men had similar times to CPR, although 5-minute or greater delays in initiating CPR was not uncommon. Delays in bystander CPR in OHCA were associated with worse survival outcomes.

BACKGROUND: Prompt initiation of bystander cardiopulmonary resuscitation (CPR) is critical to survival for out-of-hospital cardiac arrest (OHCA). However, the association between delays in bystander CPR and OHCA survival is poorly understood. METHODS: In this observational study using a nationally representative US registry, we identified patients who received bystander CPR from a layperson for a witnessed OHCA from 2013 to 2021. Hierarchical logistic regression was used to estimate the association between time to CPR (<1 minute versus 2-3, 4-5, 6-7, 8-9, and ≥10-minute intervals) and survival to hospital discharge and favorable neurological survival (survival to discharge with cerebral performance category of 1 or 2 [ie, without severe neurological disability]). RESULTS: Of 78 048 patients with a witnessed OHCA treated with bystander CPR, the mean age was 63.5±15.7 years and 25, 197 (32.3%) were women. The median time to bystander CPR was 2 (1-5) minutes, with 10% of patients having a≥10-minute delay before initiation of CPR. Overall, 15 000 (19.2%) patients survived to hospital discharge and 13 159 (16.9%) had favorable neurological survival. There was a graded inverse relationship between time to bystander CPR and survival to hospital discharge (P for trend <0.001). Compared with patients who received CPR within 1 minute, those with a time to CPR of 2 to 3 minutes were 9% less likely to survive to discharge (adjusted odds ratio, 0.91 [95% CI, 0.87-0.95]) and those with a time to CPR 4 to 5 minutes were 27% less likely to survive (adjusted odds ratio, 0.73 [95% CI, 0.68-0.77]). A similar graded inverse relationship was found between time to bystander CPR and favorable neurological survival (P for trend <0.001). CONCLUSIONS: Among patients with witnessed OHCA, there was a dose-response relationship between delays in bystander initiation of CPR and lower survival rates.

BACKGROUND: Most studies on bystander cardiopulmonary resuscitation (CPR) for out-of-hospital cardiac arrest (OHCA) have focused on in-hospital or short-term survival. OBJECTIVES: The purpose of this study was to examine the association between bystander CPR and long-term survival outcomes for OHCA. METHODS: Within the Cardiac Arrest Registry to Enhance Survival, we identified 152,653 patients with OHCA ≥65 years of age or older. Using multivariable hierarchical logistic regression, we first examined the association between bystander CPR and in-hospital survival. Then, among those surviving to discharge and linked to Medicare files, we evaluated the association between bystander CPR and long-term mortality over 5 years using multivariable Cox regression. RESULTS: Overall, 58,464 (38.3%) received bystander CPR. Patients receiving bystander CPR were more likely to have an OHCA that was witnessed, in a public location, and with an initial shockable rhythm. Bystander CPR was associated with a 24% higher likelihood of surviving to hospital discharge (10.2% vs 5.5%; adjusted relative risk: 1.24 [95% CI: 1.19-1.29]; P < 0.001), and this survival benefit was similar (interaction P = 0.24) for those who were 65 to 74, 75 to 84, and ≥85 years of age. Among patients surviving to hospital discharge (median follow-up of 31 months), bystander CPR was additionally associated with lower long-term mortality vs those without bystander CPR (adjusted hazard ratio: 0.78 [95% CI: 0.73-0.84]; P < 0.001), and this benefit was also consistent across age groups (interaction P = 0.13). CONCLUSIONS: In older adults with OHCA, bystander CPR was associated with higher rates of in-hospital survival. This survival benefit was not attenuated by competing mortality risks but increased in magnitude after hospital discharge.
