Across 16 sessions, >50 oral presentations were given on topics ranging from a first‐person narrative from a patient's perspective of surviving cardiac arrest to the transcriptional profiling of the neuroprotective mechanisms of inhaled nitric oxide in pediatric arrest. A total of 275 posters and 27 oral presentations on 40 topics were presented.1 Nine awards, including the inaugural winners of the Resuscitation Champion Award, were given.2AwardsThe Young Investigator Awards were presented to 10 investigators within the first 5 years of their appointments, honoring exemplary contributions to research in a broad range of topics (Table S1).Lifetime Achievement Awards were presented to 2 clinician‐researchers for their life‐long work and contributions to the field: Clifton W. Callaway, MD, PhD, of the University of Pittsburgh (Pittsburgh, PA) received the Lifetime Achievement Award in Cardiac Resuscitation, and Martin Schreiber, MD, of the Oregon Health and Science University (Portland, OR), received the Lifetime Achievement Award in Trauma Resuscitation Science.Dr Callaway's research has centered on improving outcomes for brain injury following cardiac arrest by implementing a medically comprehensive and titrated approach to patients while mentoring multiple investigators in the resuscitation field.2Dr Schreiber was distinguished for his roles both as a military officer and as a civilian physician and researcher. He served in 3 deployments in Iraq and Afghanistan and played a significant role in developing new resuscitation strategies including the use of recombinant factor VII, hypertonic saline, prothrombin complex concentrate, and stem cells.2The inaugural Resuscitation Champion Award, designated for individuals who support the field via research and clinical improvements in government, industry, or public advocacy, was presented to Debra Egan, MPH, and George Sopko, MD, MPH, from the National Heart, Lung and Blood Institute.The Ian G. Jacobs Award for International Group Collaboration to Advance Resuscitation Science was presented to the Core Outcome Set for Cardiac Arrest (COSCA),3 a partnership of patients, families, clinicians, researchers, and the International Liaison Committee on Resuscitation (ILCOR) that acknowledges the values and preferences of all stakeholders, particularly patients and their families.This year's Best Oral Abstract awards were presented to Linn Andelius, Emmanuel O. Akintoye, Ernesto Lopez, and Takayuki Ogura. Andelius's study focused on of the effect of smartphone applications on bystander defibrillation participation. Lopez's research evaluated antithrombin III's contribution to the protective and reparative effects of fresh frozen plasma following hemorrhagic shock. Akintoye's research highlighted the importance of modifiable social determinants such as insurance type and hospital percutaneous coronary intervention capability of health in patient outcomes as significant predictors of survival to hospital discharge after cardiopulmonary resuscitation (CPR) for in‐hospital cardiac arrest (IHCA). Ogura studied the use of the prehospital traumatic bleeding severity score as a predictor of massive transfusion utilization (Table S2). Table S3 provides names, titles, and research fields of winning abstracts.Women in Resuscitation Science Networking MeetingThis year's Women in Resuscitation Science focused on the gender pay gap and teaching salary negotiation for women in the workplace, sponsored by the American Association of University Women. During this workshop, participants learned the fundamentals of salary negotiation through facilitated discussion and role playing.Japanese Circulation Society and AHA SessionReSS continued the long tradition of a joint session between the Japanese Circulation Society and the AHA. Dr Yoshio Tahara of the National Cerebral and Cardiovascular Center Hospital (Osaka, Japan) illustrated how extracorporeal membrane oxygenation, coronary angiography, and temperature management have been aggressively implemented in Japan over the past decade. Dr Jon Rittenberger of the University of Pittsburgh (Pittsburgh, PA) shared data from the Pittsburgh Post–Cardiac Arrest Service demonstrating how the initial neurologic examination is used for prognostication and for determining the patients most likely to benefit from early coronary angiography and electroencephalography monitoring. Dr Eji Hirakawa of Nagasaki University (Nagasaki, Japan) demonstrated the difference between surface and brain temperature in the postarrest patient and discussed optimal temperature management for this population.Population Health InitiativesDispatch‐Assisted CPR: From Saving Lives to ImplementationThe plenary session, "Dispatch‐Assisted CPR: From Saving Lives to Implementation," was a multiperspective panel that described the experience of an emergent cardiac arrest from the point of view of all stakeholders, including a survivor, a family member, good Samaritans/laypeople, a rehabilitation specialist, and a dispatcher. Each panelist described the same event from his or her unique perspective, painting a multifaceted picture of the faceless heroes on the other end of the phone who make the difference between life and death. The discussion emphasized the crucial parts played by all parties in successful outcomes for cardiac arrest.Saving Lives Through Public Health InitiativesDr Bernd Böttiger from Cologne, Germany, gave an inspiring talk on the "Kids Save Lives" campaign (https://www.youtube.com/watch?v=0Yf4umHnD3c "Kids Save Lives", n.d.).4 This movement is achieving remarkable penetration in Europe, and multiple counties have enacted mandatory CPR training in public schools. Germany alone has observed a doubling from ≈20% to ≈40% in rates of bystander CPR across the country. Dr Amy Stewart from Advocate Lutheran General Hospital (Park Ridge, IL) presented her work on "Stop the Bleed, Campaign for Public Trauma Response" (https://www.bleedingcontrol.org), an effort led by the American College of Surgeons Committee on Trauma, emphasizing the role that gun violence has played in public health, particularly trauma, in the United States. The Stop the Bleed campaign still uses the "ABCs" for resuscitation: alert (call 911), find the source of bleeding, and compress. Stop The Bleed aims to empower the general public by teaching and distributing basic techniques for bleeding control.Dr Carolina Hansen from Copenhagen, Denmark, discussed the need to consider and pass legislation requiring CPR training in schools globally. She noted that the barriers to implementing CPR training in schools in Denmark and the United States are similar, particularly because of lack of knowledge and fear of teaching incorrect technique among the educators expected to teach students. She concluded by calling for better communication with and expectations of legislation for end users as a means to improve public awareness and training in CPR. Dr Mary Chang from the University of Texas Southwestern Medical Center (Dallas, TX) discussed the use of training kiosks in increasing bystander execution of CPR.Resuscitation Health Services Research, Adult and Pediatric EpidemiologyTexas researchers presented data on sex differences in outcomes among those with out‐of‐hospital cardiac arrest, finding that women, although having higher rates of return of spontaneous circulation (ROSC), have lower survival when adjusting for confounders. The session concluded with a discussion about the cost‐effectiveness of public access automated external defibrillators (AEDs). Researchers from Denmark investigated the return on investment of public AEDs. Their findings suggest that it costs about $54 000 for public AEDs to provide 1 quality‐adjusted life‐year, which is well within World Health Organization and AHA high/intermediate values for interventions.Dr Victoria L. Vetter from the Children's Hospital of Philadelphia discussed the impact of legislation in 38 states requiring CPR training as a graduation requirement. Although "CPR in Schools" is associated with a 17% to 25% increase in bystander CPR rates across all ages and in every state where it was enacted, significant disparities among gender and race still exist.Dr Mathias J. Holmberg from Beth Israel Deaconess Medical Center (Boston, MA) presented a new analysis of "Get With The Guidelines–Resuscitation" to measure the incidence of IHCA in US hospitals. Compared with previous estimates, there are >310 000 IHCA victims in the United States annually, suggesting a large and growing burden of disease. Meanwhile, the number of pediatric IHCAs has decreased, estimated at ≈7100 annually, demonstrating that IHCA is often predictable and thus preventable.Dr Lars W. Andersen from Aarhus University in Denmark and his team presented a cost‐effectiveness analysis of public access defibrillation. He concluded that public access defibrillation costs $54 000 for each quality‐adjusted life‐year saved. The cost of public access defibrillation per quality‐adjusted life‐year saved meets the generally accepted threshold of $50 000 per quality‐adjusted life‐year for cost‐effectiveness and is comparable to other generally accepted cardiovascular interventions considered efficacious.Researchers from Michigan, now a statewide partner in CARES (Cardiac Arrest Registry to Enhance Survival), presented data on the estimated patient‐standardized clinical outcomes for OHCA across emergency medical services (EMS) agencies in Michigan. Significant variability exists, with the highest performing EMS agencies achieving 40% ROSC and the lower performing agencies achieving 11% ROSC.Improving CPR Education for Laypeople and ProfessionalsDuring the closing session of ReSS, several presentations discussed issues surrounding improving CPR education and decreasing barriers to layperson response. In the United States, state legislation requiring CPR training in schools has resulted in more people trained and an increase in the number of patients discharged after cardiac arrest with favorable functional outcomes. Nevertheless, gender and racial gaps remain regarding lay rescuer response among those studied.Closed caption television videos were reviewed to observe and describe what real‐life cardiac arrest events look like in the out‐of‐hospital setting. For patients suffering cardiac arrest, there is often a prodrome of unsteady gait, agonal breathing, and abnormal posturing. For lay rescuers responding, responses range from shaking or shouting at the person, holding the head of the person, and attempting to stand them up or lift their legs. In an Arizona community, residents were engaged, trained, and asked to voluntarily take calls to allow researchers to study the response time of lay rescuers versus EMS providers for both chest compressions and AED delivery. In multiple simulated scenarios, lay rescuers demonstrated faster response times compared with EMS. In Australia, cardiac rehabilitation patients were targeted for increased CPR training efforts. Preliminary results suggest that CPR training can be implemented in cardiac rehabilitation programs but that time requirement to do so is still a barrier to implementation.Last, researchers from the University of Pennsylvania (Philadelphia, PA) presented data on the implications of legislative efforts for CPR education. This presentation utilized national telephone survey data on CPR education to compare states with mandates for implementation of CPR training in school education to those without. The findings suggest that in states with current mandates, the younger population (aged 18–24 years) is significantly more likely to be trained.

Dr Henry Wang of the University of Alabama (Birmingham, AL) presented, "EMS Approaches to Airway in the US: Pragmatic Airway Resuscitation (PART) Trial,"5 a pragmatic trial of supraglottic (laryngeal) airway versus endotracheal tube placement in the prehospital setting conducted within the network of the Resuscitation Outcomes Consortium (ROC) in North America. Patients were randomized in clusters with a crossover design, and the primary outcome was survival at 72 hours. Results demonstrated a significant benefit for patients managed with a laryngeal tube across the primary and 3 secondary outcome measures (ROSC, hospital discharge, and favorable functional outcome).Dr Pierre Carli, from the Necker‐Enfants Malades Hospital (Paris, France) presented, "EMS Approaches to Airway in the Cardiac Arrest Airway Management (CAAM) Trial." CAAM is a prehospital noninferiority trial of bag‐mask ventilation versus endotracheal tube (control group) conducted in Europe, where the standard practice involves airway management performed by physicians. Patients were randomized on scene, and the primary outcome was survival with good functional outcome (cerebral performance category 1–2 at 28 days). Results from the intention‐to‐treat analysis showed no significant difference in outcome between groups.Dr. Jerry Nolan from the Royal United Hospital in Bath UK, presented results from the study: Effect of a Strategy of a Supraglottic Airway Device vs Tracheal Intubation During Out‐of‐Hospital Cardiac Arrest on Function Outcome, The AIRWAYS‐2 Randomized Clinical Trial. Clustering occurred at the EMS level, and the primary outcome was good functional outcome at 30 days or hospital discharge, whichever occurred first. Results demonstrated a significant benefit for patients managed with a supraglottic airway regarding initial airway success but also the loss of an established initial airway. In sensitivity analysis, patients with good functional recovery were significantly more likely to have had the supraglottic airway first (odds ratio: 2.06; 95% CI, 1.51–2.81), compared with the tracheal intubation group.Dr Daniel W. Spaite from the University of Arizona (Tucson, AZ) presented, "Airway Management and Ventilation During Traumatic Injury." Dr Spaite highlighted that trials on airway management are likely confounded by differences in ventilation practices, unintentionally because ventilation is not standardized or measured consistently. More attention to ventilation technique is needed for clinical practice, and future airway trials must consider how to control for ventilation variation and impact.Circulatory Support for Cardiac and Trauma EmergenciesThe plenary session, "Circulatory Support for Cardiac and Trauma Emergencies," featured a panel of international experts discussing strategies to treat cardiovascular and traumatic shock. Dr Theresa M. Olasveengen from Oslo, Norway, showed preclinical data demonstrating how these models have been used to determine the optimal timing for delivery of therapies and serve to evaluate novel therapies that may save lives in the future. Dr Paula Ferrada from Virginia Commonwealth University (Richmond, VA) reviewed indications for both tourniquets and resuscitative endovascular balloon occlusion of the aorta as temporalizing methods to control exsanguinating traumatic shock. Dr Jason Bartos from the University of Minnesota (Minneapolis, MN) shared compelling data demonstrating that 100% of his OHCA patients treated with extracorporeal life support experience multiple organ failure, and 84% have coronary artery disease. Dr Babar Basir from Detroit, Michigan, showed how a shock "system of care" successfully implemented in Detroit integrated EMS, emergency department, and in‐hospital care.New Insights Into Postarrest Assessment and CareThe session "New Insights Into Post‐Arrest Assessment and Care" was presented on an array of long‐term effects of cardiac arrest. Dr Sachin Agarwal of Columbia University (New York, NY) reported on a study of 114 cardiac arrest survivors over 12 months. He noted that survivors have a 36% screened positive rate for posttraumatic stress disorder at hospital discharge and 28% at 1 year after cardiac arrest. These participants tended to be younger and female and to have preexisting psychiatric diagnoses. Participants with posttraumatic stress disorder had consistently higher risk of 12‐month risk of major adverse cardiac events and all‐cause mortality.7Dr Matthias Kohlhauer of Maisons‐Alfort, France, presented data from a rabbit model of cardiac arrest instrumented to capture temperature, cerebral blood flow, cerebral vascular resistance, and arterial/venous differences in cerebral glucose, oxygen, and metabolic substrates. He found that ultra‐rapid induction of hypothermia with total liquid ventilation reduced cerebral consumption of oxygen and glucose and reversed the lactate/pyruvate ratio compared with control animals.8Dr Marco Hefti of the University of Iowa in Iowa City described a piglet model of pediatric cardiac arrest in which animals were randomized to inhaled nitric oxide or control after ROSC. Transcriptional profiling of cerebral tissue revealed differential gene expression related to synaptic transmission.Dr Min Yang of Anhui Medical University (Hefei, China) noted the prevalence of postmyocardial dysfunction in the post–cardiac arrest syndrome and that exposure to epinephrine during resuscitation seems to exacerbate it. She tested ivabradine, a pharmacologic agent that reduces heart rate by inhibiting specific portions of the intrinsic pacemaker current, as a protective agent in a porcine model of cardiac arrest. Animals receiving ivabradine had lower heart rates, less echocardiographic evidence of myocardial dysfunction, and less histologic evidence of myocardial injury compared with controls.Dr Ramani Balu of the University of Pennsylvania (Philadelphia, PA) presented human data on dynamic cerebrovascular autoregulation from a single‐center cohort of human participants with diffuse hypoxic brain injury. Cerebrovascular pressure reactivity manifested in different phenotypes in participants who regained consciousness or remained in a vegetative state. Furthermore, cerebrovascular pressure reactivity had better discrimination of participants with and without eventual return of consciousness than intracranial pressure or brain tissue oxygenation.Exploring Devices and AlgorithmsA session exploring the use of devices and algorithms in resuscitation drew considerable attention as presenters shared data on the use of extracorporeal membrane oxygenation in patients with prolonged resuscitation, examined the associated outcomes of intravenous versus intraosseous access in OHCA, and introduced a novel AED algorithm that allows for continuous chest compressions while the device measures a rhythm, reducing resuscitation interruptions markedly. Dr Felipe Teran from the University of Pennsylvania (Philadelphia, PA) gave a visually captivating presentation on the use of transesophageal echocardiography intra‐arrest in OHCA patients with preliminary data demonstrating safety, feasibility, and clinical impact. A key finding of this preliminary work is that in 41% of cardiac arrest cases, the area of maximal compression was found in the left ventricle; in the other 53%, it was in the aortic root or left ventricular outflow tract.9Dr Corina De Graff from Academisch Medisch Centrum Amsterdam presented on her team's work on prospectively evaluating a new algorithm (cprINSIGHT) which can analyze the ECG while rescuers continue CPR. The results show that this novel algorithm could analyze the ECG without the need for a pause in chest compressions 65% to 74% of the time and had 90% to 100% sensitivity and 100% specificity when it made a shock or a no shock decision.Dr Jason Bartos from the University of Minnesota presented a study examining the effects of resuscitation duration on neurologically intact survival in the Minnesota ROC extracorporeal cardiopulmonary resuscitation protocol. They found that 41% of patients receiving full resuscitative efforts were discharged neurologically intact; however, neurologically intact survival declined with increasing duration of CPR, with 100% survival in patients placed on extracorporeal life support within 30 minutes. Survival declined to 50% within 50 minutes and to 20% within 70 minutes, and the metabolic profile worsened during prolonged CPR.A popular topic in this year's agenda was the comparison of intraosseous versus intravenous access for the delivery of advanced life support drugs. Dr Purav Mody from the University of Texas Southwestern (Dallas, TX) brought us further discussion of this topic with a presentation of data from the ROC Continuous Chest Compression Trial.10 Among 19 731 patients with available access information, intraosseous or intravenous access was attempted in 15.5% and 84.5% of patients, respectively, and was successful in 97% and 92% of these patients. Patients with attempted intraosseous access were actually very different: they were younger, were more likely female, received less bystander CPR, had lower proportions of shockable and witnessed arrests, had marginally faster times to access and to epinephrine administration, and less frequently received therapeutic hypothermia and coronary angiography compared with patients with intravenous access.

The trial demonstrated higher 30‐day survival for the epinephrine group (3.2% epinephrine versus 2.4% for placebo) but not in survival with favorable neurologic outcome on discharge (2.2% in the epinephrine group and 1.9% in the placebo group). Dr Peter J. Kudenchuk of the University of Washington (Seattle, WA) presented a secondary analysis from the ROC. Their goal was to determine whether intraosseous or intravenous administration of medication was associated with outcome. Although the intraosseous group received a higher percentage of CPR during their resuscitation, the survival benefit of administering amiodarone or lidocaine was not found in the intraosseous group. Administering amiodarone or lidocaine did improve survival in the intravenous group. Dr Jasmeet Soar, chair of the advanced life support subcommittee of Southmead Hospital (Bristol, UK), then revealed the new ILCOR recommendations on antiarrhythmic drug use during CPR and after ROSC.12 Given the results of the above trial, either lidocaine or amiodarone can be used in ventricular fibrillation/ventricular tachycardia cardiac arrest. These 2 presentations illustrated how ILCOR rapidly incorporated new data into its guidelines.Year In Review: Trauma and Cardiac ArrestAt the cardiac year in review, Dr
