We aimed to elucidate gaps in the provision of cognitive and psychological resources in cardiac arrest survivors. We conducted an online survey study between October 29, 2019, and November 15, 2019 with cardiac arrest survivors and caregiver members of the Sudden Cardiac Arrest Foundation. We queried survivors as to whether they experienced cognitive or psychological symptoms since their cardiac arrest. Next, we queried both survivors and caregivers on the provision of resources through three metrics: (1) discussions with providers about potential cognitive or psychological symptoms, (2) neurologist or psychologist appointments scheduled by providers, and (3) mental health referrals by providers. We then ran Chi-square goodness-of-fit tests to compare the proportion of survivors and caregivers who reported resource provision (observed values) to the proportion of survivors who reported experiencing cognitive and psychological symptoms, respectively (expected values). We included responses from 167 survivors and 52 caregivers. A total of 73.1% (n = 122) survivors reported experiencing cognitive symptoms and 67.1% (n = 112) psychological symptoms since their cardiac arrest. When compared to these two proportions, provision of resources was significantly lower in all three metrics: (1) fewer discussions with providers about potential for developing cognitive symptoms (31%) and psychological symptoms (26.3%), (2) fewer neurologist appointments scheduled (8.4%) and psychologist appointments scheduled (4.8%), and (3) fewer referrals to mental health (6%). Informal caregivers also reported significantly lower provision of resources in all three metrics, with the exception of discussions about developing cognitive symptoms. Our results suggest that there are discrepancies in the provision of cognitive and psychological resources in cardiac arrest survivors with good neurologic recovery. Systematic referral processes may be needed to standardize resource provision to consistently meet the pervasive cognitive and psychological needs of cardiac arrest survivors.

While much has been observed regarding hypothermia by way of environmental exposure, it is modern day medicine that deployed hypothermia as a therapeutic. From the early 1930s, when Temple Fay deployed "refrigeration" to treat pain, to the work of Wilfred Bigelow and Charles Drew, who utilized hypothermia in open heart surgery-the opportunities seemed endless. However, questions arose surrounding appropriate temperatures to achieve best outcomes and how to minimize adverse events, such as coagulopathy and infection. In the 1980s, hypothermia underwent a resurgence through Peter Safar's critical studies in large animals, which quickly translated into feasibility studies and the landmark trials of 2002 that paved the way for postcardiac arrest care as we currently know it. Through clinical and observational trials, modern-day targeted temperature management continues to adapt, striving to improve patient outcomes. While hypothermia has come a long way from the writings of Hippocrates, the ideal therapy has not yet been defined, and more work is needed. While the history is long, there is more to be written and advances to be achieved as we optimize the neuroprotective effects of hypothermia for comatose survivors of cardiac arrest.

The Emergency Medical Services constitutes a critical component in treating patients with out-of-hospital cardiac arrest (OHCA). Activating the EMS system is the first important step in deploying resources, but community involvement in the care of emergent patients is multifaceted and complex. How does the public access EMS services versus other modes of transport remains under investigated; and if the public opts for a different mode of transport to the hospital, how does this affect outcomes?

Preliminary data have produced conflicting results regarding whether initial vitamin C levels in patients with severe sepsis correlate with mortality outcomes. We hypothesized that low plasma ascorbic acid or thiamine levels in severe sepsis patients admitted from the Emergency Department (ED) to the Intensive Care Unit (ICU) would be associated with increased mortality and an increased incidence of shock. Retrospective analysis of a prospective database of severe sepsis patients admitted to the ICU at an urban, academic medical center. Ascorbic acid and thiamine levels were analyzed in relation to survivors vs. non-survivors and shock vs. non-shock patients. 235 patients were included; mean age, 59.4 years ± 16.8 years; male, 128 (54.5%); in-hospital mortality, 16.6% (39/235); mean APACHE3 score, 61.8 ± 22.8; mean ascorbic acid level (reference range 0.40–2.10 mg/dL), 0.23 mg/dL (95% CI 0.07–4.02); and the mean thiamine level (reference range 14.6–29.5 nmol/L), 6.0 nmol/L (95% CI 4.0–9.5). When survivors were compared to non-survivors, survivors were more likely to be male (57.7% [113/196] vs. 38.5% [15/39]) and have lower APACHE3 scores (58.2 ± 22.6 vs. 79.9 ± 16.0). For the total cohort of 235 patients, there was no statistically significant relationship between a patient’s initial ascorbic acid or thiamine level and either survival or development of shock. In this analysis of early plasma samples from patients with severe sepsis admitted from the ED to the ICU, we found that mean ascorbic acid and thiamine levels were lower than normal range but that there was no relationship between these levels and outcomes, including 28 day mortality and development of shock.

PURPOSE OF REVIEW: The emergence of severe acute respiratory syndrome coronavirus 2 virus, which causes coronavirus disease 2019 (COVID-19), led to the declaration of a global pandemic by the World Health Organization on March 11, 2020. As of February 6, 2021, over 105 million persons have been infected in 223 countries and there have been 2,290,488 deaths. As a result, emergency medical services and hospital systems have undergone unprecedented healthcare delivery reconfigurations. Here, we review the effects of the COVID-19 pandemic on out-of-hospital cardiac arrest (OHCA) epidemiology and systems of care. RECENT FINDINGS: Areas severely affected by the pandemic have reported increased incidence of OHCA, lower rates of successful resuscitation, and increased mortality. COVID-19 has significantly impacted patient outcomes through increased disease severity, decreased access to care, and the reshaping of emergency medical response and hospital-based healthcare systems and policies. The pandemic has negatively influenced attitudes toward resuscitation and challenged providers with novel ethical dilemmas provoked by the scarcity of healthcare resources. SUMMARY: The COVID-19 pandemic has had direct, indirect, psychosocial, and ethical impacts on the cardiac arrest chain of survival.

The quick sequential organ failure assessment (qSOFA) score has been proposed as a means to rapidly identify adult patients with suspected infection, in pre-hospital, Emergency Department (ED), or general hospital ward locations, who are in a high-risk category with increased likelihood of “poor outcomes:” a greater than 10% chance of dying or an increased likelihood of spending 3 or more days in the ICU. This score is intended to replace the use of systemic inflammatory response syndrome (SIRS) criteria as a screening tool; however, its role in ED screening and identification has yet to be fully elucidated. In this retrospective observational study, we explored the performance of triage qSOFA (tqSOFA), maximum qSOFA, and first initial serum lactate (> 3 mmol/L) at predicting in-hospital mortality and compared these results to those for the initial SIRS criteria obtained in triage. A total of 2859 sepsis cases were included and the in-hospital mortality rate was 14.4%. The sensitivity of tqSOFA ≥ 2 and maximum qSOFA ≥ 2 to predict in-hospital mortality were 33% and 69%, respectively. For comparison, the triage SIRS criteria and the initial lactate > 3 mmol/L had sensitivities of 82% and 65%, respectively. These results demonstrate that in a large ED sepsis database the earliest measurement of end organ impairment, tqSOFA, performed poorly at identifying patients at increased risk of mortality and maximum qSOFA did not significantly outperform initial serum lactate levels.

This 2020 International Consensus on Cardiopulmonary Resuscitation (CPR) and Emergency Cardiovascular Care Science With Treatment Recommendations on basic life support summarizes evidence evaluations performed for 20 topics that were prioritized by the Basic Life Support Task Force of the International Liaison Committee on Resuscitation. The evidence reviews include 16 systematic reviews, 3 scoping reviews, and 1 evidence update. Per agreement within the International Liaison Committee on Resuscitation, new or revised treatment recommendations were only made after a systematic review. Systematic reviews were performed for the following topics: dispatch diagnosis of cardiac arrest, use of a firm surface for CPR, sequence for starting CPR (compressions-airway-breaths versus airway-breaths-compressions), CPR before calling for help, duration of CPR cycles, hand position during compressions, rhythm check timing, feedback for CPR quality, alternative techniques, public access automated external defibrillator programs, analysis of rhythm during chest compressions, CPR before defibrillation, removal of foreign-body airway obstruction, resuscitation care for suspected opioid-associated emergencies, drowning, and harm from CPR to victims not in cardiac arrest. The topics that resulted in the most extensive task force discussions included CPR during transport, CPR before calling for help, resuscitation care for suspected opioid-associated emergencies, feedback for CPR quality, and analysis of rhythm during chest compressions. After discussion of the scoping reviews and the evidence update, the task force prioritized several topics for new systematic reviews.

This2020 International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendationsfor advanced life support includes updates on multiple advanced life support topics addressed with 3 different types of reviews. Topics were prioritized on the basis of both recent interest within the resuscitation community and the amount of new evidence available since any previous review. Systematic reviews addressed higher-priority topics, and included double-sequential defibrillation, intravenous versus intraosseous route for drug administration during cardiac arrest, point-of-care echocardiography for intra-arrest prognostication, cardiac arrest caused by pulmonary embolism, postresuscitation oxygenation and ventilation, prophylactic antibiotics after resuscitation, postresuscitation seizure prophylaxis and treatment, and neuroprognostication. New or updated treatment recommendations on these topics are presented. Scoping reviews were conducted for anticipatory charging and monitoring of physiological parameters during cardiopulmonary resuscitation. Topics for which systematic reviews and new Consensuses on Science With Treatment Recommendations were completed since 2015 are also summarized here. All remaining topics reviewed were addressed with evidence updates to identify any new evidence and to help determine which topics should be the highest priority for systematic reviews in the next 1 to 2 years.

BACKGROUND: While survival after in-hospital cardiac arrest (IHCA) has improved in recent years, it remains unknown whether this trend primarily applies to younger IHCA victims. The aim of this study was to assess trends in survival to hospital discharge after adult IHCA across age groups from 2000 to 2016.METHODS: This is an observational study of IHCA patients included in the Get With The Guidelines®-Resuscitation registry between 2000 and 2016. The primary outcome was survival to hospital discharge. Patients were stratified into five age groups: RESULTS: A total of 234,767 IHCA patients were included. The absolute increase in survival per calendar year was 0.8% (95% CI 0.7-1.0%, p CONCLUSIONS: For patients with IHCA, rates of survival to discharge have improved significantly from 2000 to 2016 across all age groups.

OBJECTIVE: Elucidate how physicians formulate a neurological prognosis after cardiac arrest and compare differences between experts and general providers. METHODS: We performed semi-structured interviews with experts in post-arrest care and general physicians. We created an initial model and interview guide based on professional society guidelines. Two authors independently coded interviews based on this initial model, then identified new topics not included in it. To describe individual physicians’ cognitive approach to prognostication, we created a graphical representation. We summarized these individual “mental models” into a single overall model, as well as two models stratified by expertise. RESULTS: We performed 36 interviews (17 experts and 19 generalists), most of whom practice in Europe (23) or North America (12). Participants described their approach to prognosis formulation as complex and iterative, with sequential and repeated data acquisition, interpretation, and prognosis formulation. Eventually, this cycle results in a final prognosis and treatment recommendation. Commonly mentioned factors were diagnostic test performance, time from arrest, patient characteristics. Participants also discussed factors rarely discussed in prognostication research including physician and hospital characteristics. We found no substantial differences between experts and general physicians. CONCLUSION: Physicians’ cognitive approach to neurologic prognostication is complex and influenced by many factors, including some rarely considered in current research. Understanding these processes better could inform interventions designed to aid physicians in prognostication.

Targeted temperature management (TTM) has become a cornerstone in the treatment of comatose post-cardiac arrest patients over the last two decades. Belief in the efficacy of this intervention for improving neurologically intact survival was based on two trials from 2002, one truly randomized-controlled and one small quasi-randomized trial, without clear confirmation of that finding. Subsequent large randomized trials reported no difference in outcomes between TTM at 33 vs. 36°C and no benefit of TTM at 33°C as compared with fever control alone. Given that these results may help shape post-cardiac arrest patient care, we sought to review the history and rationale as well as trial evidence for TTM, critically review the TTM2 trial, and highlight gaps in knowledge and research needs for the future. Finally, we provide contemporary guidance for the use of TTM in daily clinical practice.

Introduction: Surrogate decision makers (SDMs) represent critical stakeholders in decision making for comatose survivors of cardiac arrest, yet these individuals are often unprepared for decision making and unfamiliar with the complexity of post-cardiac arrest care. To that end, we created a decision aid for SDMs intended to inform and support evidence-based decision making for comatose survivors of cardiac arrest. Methods: We conducted a pilot trial to measure real world effectiveness of the Tool to EMPOwer (TEMPO) Surrogate Decision Makers, by measuring knowledge and acceptability. Individuals were enrolled who self-identified as the SDM for a comatose survivor of OHCA admitted to an academic tertiary care hospital. Participants completed a pre-intervention survey prior to the provision of TEMPO, and a post-intervention survey approximately 24 hours after exposure to the intervention. Pre-survey questions included SDM demographics and an 8-question knowledge survey. Post-intervention surveys included the same knowledge questions, the Ottawa Acceptability of Decision Aid tool, and questions to measure if SDMs shared TEMPO with others. This study was approved by the Colorado Multiple Institutional Review Board and registered at Clinicaltrials.gov (NCT03908346). Results: Twenty SDMs were enrolled between 9/1/2020 and 6/7/2021. One subject did not complete the post-intervention survey therefore 19 subject responses were analyzed for the purpose of this report. Participants were 85.0% Female, 47.4 +/- 14.8 years, and 45.0% were the spouse of the patient. In the 8-question knowledge survey, results improved from 57.2% correct to 90.8% correct after exposure to TEMPO (p Conclusion: Initial pilot data on the efficacy of the Tool to EMPOwer Surrogate Decision Makers of comatose survivors of cardiac arrest shows significant promise in improving knowledge and supporting decision-making.

Introduction: We sought to identify correlates with psychological symptoms in long-term cardiac arrest (CA) survivors. Mindfulness, or nonjudgmental awareness of the present moment, is a modifiable protective factor against psychological symptoms in various clinical populations and could be a potential treatment target for CA survivors. Methods: We conducted a longitudinal survey study between 10-11/2019 (baseline) and 10-11/2020 (1-year follow-up) with long-term CA survivor members of the Sudden Cardiac Arrest Foundation. We collected demographic and CA characteristics at baseline. At both timepoints, we assessed posttraumatic stress symptoms (PTS) through the PTSD Checklist-5 (PCL-5) and depression and anxiety symptoms through the Patient Health Questionnaire-4 (PHQ-4). At follow-up, we assessed mindfulness through the Cognitive and Affective Mindfulness Scale-Revised (CAMS-R). We used adjusted linear regression to predict 1-year PCL-5 and PHQ-4 scores, with particular consideration of the CAMS-R as a cross-sectional correlate of outcome. Results: We included 129 CA survivors (mean age: 52 years, 52% male, 98% white). At 1-year follow-up, in adjusted models, CAMS-R (β: -0.35, p Conclusion: Mindfulness was inversely associated with psychological symptoms in long-term CA survivors. Future studies should examine the longitudinal relationship of mindfulness and psychological symptoms after CA.

Introduction: Surrogate decision makers (SDMs) for comatose survivors of cardiac arrest are often charged with making time-sensitive complex decisions with regard to life-sustaining therapies in a sudden critical illness. We describe the development of a decision aid for SDMs of comatose survivors of cardiac arrest. Methods: Applying recommendations from the International Patient Decision Aid Standards, we developed this decision aid iteratively with the purpose to educate families on post-arrest care and evidence based decision-making. We obtained feedback from stakeholders, including surrogate decision makers, patients, caregivers, nurses and physicians, in focus groups and semi-structured interviews. Results: Informed by interviews with SDMs and the AHA Guidelines, we designed a prototype of the decision aid. Each iteration resulted in a refined version of the aid (Figure). Step 1 included feedback from the Shared Decision-Making Core at the Adult and Child Consortium on Outcomes Research and Delivery Science (ACCORDS). Step 2 incorporated feedback from the ACCORDS Community Engagement Stakeholder group. Step 3 consisted of 10 semi-structured interviews with informal caregivers and patient pairs within the Advanced Heart Failure or Seniors clinics. The document was then reviewed by a team of expert cardiac arrest stakeholders. The aid includes key definitions, a timeline of post-arrest care, factors that support decisions to discontinue or pursue life sustaining therapies, commonly asked questions and an illustration of a patient undergoing post-arrest treatment. The decision aid, entitled T ool to EMPO wer (TEMPO) Surrogate Decision Makers, is written at a 7 th grade reading level. Conclusions: Through a robust iterative process, we designed a decision aid for SDMs of comatose survivors of cardiac arrest. The aid is intended to support the decision to pursue or forego further life-sustaining therapy and to be informative about post-arrest care.

Background Variation exists in outcomes following out‐of‐hospital cardiac arrest (OHCA), but whether racial and ethnic disparities exist in post‐arrest provision of targeted temperature management (TTM) is unknown. Methods and Results We performed a retrospective analysis of a prospectively collected cohort of patients who survived to admission following OHCA from the Cardiac Arrest Registry to Enhance Survival, whose catchment area represents ~50% of the United States from 2013‐2019. Our primary exposure was race/ethnicity and primary outcome was utilization of TTM. We built a mixed‐effects model with both state of arrest and admitting hospital modeled as random intercepts to account for clustering. Among 96,695 patients (24.6% Black, 8.0% Hispanic/Latino, 63.4% White), a smaller percentage of Hispanic/Latino patients received TTM than Black or White patients (37.5% vs. 45.0 % vs 43.3%, P < .001) following OHCA. In the mixed‐effects model, Black patients (Odds Ratio [OR] 1.153, 95% Confidence Interval [CI] 1.102‐1.207, P < .001) and Hispanic/Latino patients (OR 1.086, 95% CI 1.017‐1.159, P < .001) were slightly more likely to receive TTM compared to White patients, perhaps due to worse admission neurological status. We did find community level disparity as Hispanic/Latino‐serving hospitals (defined as the top decile of hospitals that cared for the highest proportion of Hispanic/Latino patients) provided less TTM (OR 0.587, 95% CI 0.474 to 0.742, P < .001). Conclusions Reassuringly, we did not find evidence of intrahospital or interpersonal racial or ethnic disparity in the provision of TTM. However, we did find inter‐hospital, community level disparity. Hispanic/Latino‐serving hospitals provided less guideline‐recommended TTM after OHCA.

Women experience worse neurological outcomes following out-of-hospital cardiac arrest (OHCA). It is unknown whether sex disparities exist in the use of targeted temperature management (TTM), a standard of care treatment to improve neurological outcomes.We performed a retrospective study of prospectively collected patients who survived to hospital admission following OHCA from the Cardiac Arrest Registry to Enhance Survival from 2013 through 2019. We compared receipt of TTM by sex in a mixed-effects model adjusted for patient, arrest, neighborhood, and hospital factors, with the admitting hospital modeled as a random intercept.Among 123,419 patients, women had lower rates of shockable rhythms (24.4 % vs. 39.2%, P .001) and lower rates of presumed cardiac aetiologies for arrest (74.3% vs. 81.1%, P .001). Despite receiving a similar rate of TTM in the field (12.1% vs. 12.6%, P = .02), women received less TTM than men upon admission to the hospital (41.6% vs. 46.4%, P .001). In an adjusted mixed-effects model, women were less likely than men to receive TTM (Odds Ratio 0.91, 95% Confidence Interval 0.89 to 0.94). Among the 27,729 patients with data indicating the reason for not using TTM, a higher percentage of women did not receive TTM due to Do-Not-Resuscitate orders/family requests (15.1% vs. 11.4%, p .001) and non-shockable rhythms (11.1% vs. 8.4%, p .001).We found that women received less TTM than men, likely due to early care limitations and a preponderance of non-shockable rhythms.

Identifying correlates of psychological symptoms in cardiac arrest (CA) survivors is a major research priority. In this longitudinal survey study, we evaluated associations between mindfulness, baseline psychological symptoms, and 1-year psychological symptoms in long-term CA survivors. We collected demographic and CA characteristics at baseline. At both timepoints, we assessed posttraumatic stress symptoms (PTS) through the PTSD Checklist-5 (PCL-5) and depression and anxiety symptoms through the Patient Health Questionnaire-4 (PHQ-4). At follow-up, we assessed mindfulness through the Cognitive and Affective Mindfulness Scale-Revised (CAMS-R). We used adjusted linear regression to predict 1-year PCL-5 and PHQ-4 scores, with particular consideration of the CAMS-R as a cross-sectional correlate of outcome. We included 129 CA survivors (mean age: 52 years, 52% male, 98% white). At 1-year follow-up, in adjusted models, CAMS-R (β: -0.35, p 0.001) and baseline PCL-5 scores (β: 0.56, p 0.001) were associated with 1-year PCL-5 scores. CAMS-R (β: -0.34, p 0.001) and baseline PHQ-4 scores were associated with 1-year PHQ-4 scores (β: 0.37, p 0.001). In conclusion, mindfulness was inversely associated with psychological symptoms in long-term CA survivors. Future studies should examine the longitudinal relationship of mindfulness and psychological symptoms after CA.

PURPOSE: Women who experience out-of-hospital cardiac arrest have similar rates of survival to hospital admission as men; however, women are less likely to survive to hospital discharge. We hypothesized that women would have higher rates of “do not attempt resuscitation” (DNAR) orders and that this order would be associated with lower use of aggressive interventions. METHODS: We identified adult hospital admissions with a diagnosis of cardiac arrest (ICD-9 427.5) from the 2010 California State Inpatient Dataset. Multivariable logistic regression was used to test the association between patient sex and a DNAR order within the first 24 h of admission, adjusting for patient demographic characteristics and comorbid medical conditions. In secondary analysis, procedures performed after establishment of DNAR order and survival to hospital discharge were compared by sex. FINDINGS: We analyzed 6562 patients (44% women, 56% men) who experienced out-of-hospital cardiac arrest and survived to hospital admission. In unadjusted analysis, more women than men had establishment of a DNAR order during the first 24 h of admission (23.4% versus 19.3%; P < 0.01). After adjusting for age, race, and comorbid conditions, women remained significantly more likely to have a DNAR order established during the first 24 h of their hospital admission after cardiac arrest compared with men (odds ratio = 1.23; 95% CI,1.09–1.40). No sex difference was found in procedures used after DNAR order was established. IMPLICATIONS: Female survivors of cardiac arrest are significantly more likely than men to have a DNAR order established within the first 24 h of in-hospital treatment. The establishment of a DNAR order is associated with patients undergoing fewer procedures than individuals who do not have a DNAR order established. Given that patients who have a DNAR order receive less-aggressive intervention after arrest, it is possible that an early DNAR order may contribute to sex differences in survival to hospital discharge.

Background: Women who suffer an out-of-hospital cardiac arrest receive bystander cardiopulmonary resuscitation (CPR) less often than men. Understanding public perceptions of why this occurs is a necessary first step toward equitable application of this potentially life-saving intervention. Methods: We conducted a national survey of members of the public using Mechanical Turk, Amazon’s crowdsourcing platform, to determine reasons why women might receive bystander CPR less often than men. Eligible participants were adults (≥18 years) located in the United States. Responses were excluded if the participant was not able to define CPR correctly. Participants were asked to answer the following free-text question: “Do you have any ideas on why women may be less likely to receive CPR than men when they collapse in public?” Descriptive statistics were used to define the cohort. The free-text response was coded using open coding, and major themes were identified via classical content analysis. Results: In total, 548 subjects were surveyed. Mean age was 38.8 years, and 49.8% were female. Participants were geographically distributed as follows: 18.5% West, 9.2% Southwest, 22.0% Midwest, 27.5% Southeast, and 22.9% Northeast. After analysis, 3 major themes were detected for why the public perceives that women receive less bystander CPR. They include the following: (1) sexualization of women’s bodies; (2) women are weak and frail and therefore prone to injury; and (3) misperceptions about women in acute medical distress. Overall, 41.9% (227) were trained in CPR while 4.4% reported having provided CPR in a medical emergency. Conclusions: Members of the general public perceive fears about inappropriate touching, accusations of sexual assault, and fear of causing injury as inhibiting bystander CPR for women. Educational and policy efforts to address these perceptions may reduce the sex differences in the application of bystander CPR.

Opioid overdose is the leading cause of death for Americans 25 to 64 years of age, and opioid use disorder affects >2 million Americans. The epidemiology of opioid-associated out-of-hospital cardiac arrest in the United States is changing rapidly, with exponential increases in death resulting from synthetic opioids and linear increases in heroin deaths more than offsetting modest reductions in deaths from prescription opioids. The pathophysiology of polysubstance toxidromes involving opioids, asphyxial death, and prolonged hypoxemia leading to global ischemia (cardiac arrest) differs from that of sudden cardiac arrest. People who use opioids may also develop bacteremia, central nervous system vasculitis and leukoencephalopathy, torsades de pointes, pulmonary vasculopathy, and pulmonary edema. Emergency management of opioid poisoning requires recognition by the lay public or emergency dispatchers, prompt emergency response, and effective ventilation coupled to compressions in the setting of opioid-associated out-of-hospital cardiac arrest. Effective ventilation is challenging to teach, whereas naloxone, an opioid antagonist, can be administered by emergency medical personnel, trained laypeople, and the general public with dispatcher instruction to prevent cardiac arrest. Opioid education and naloxone distributions programs have been developed to teach people who are likely to encounter a person with opioid poisoning how to administer naloxone, deliver high-quality compressions, and perform rescue breathing. Current American Heart Association recommendations call for laypeople and others who cannot reliably establish the presence of a pulse to initiate cardiopulmonary resuscitation in any individual who is unconscious and not breathing normally; if opioid overdose is suspected, naloxone should also be administered. Secondary prevention, including counseling, opioid overdose education with take-home naloxone, and medication for opioid use disorder, is important to prevent recurrent opioid overdose.

OBJECTIVE Career paths leading to department chair positions are elusive. Women represent only 11% of academic emergency department (ED) chairs. It is unclear whether the pathway to chair is different for men and women; the characteristics, achievements, and qualifications among those who become ED chairs is unknown. METHODS This study is a cross-sectional analysis of curriculum vitae (CV) of current ED chairs in departments with Accreditation Council for Graduate Medical Education (ACGME)-accredited residency programs. Former women chairs were included due to paucity of current women chairs. Statistics were calculated using bivariate and multivariate analysis. RESULTS Of 163 eligible chairs, 88 CV (54%) were obtained, including six former women chairs. A majority (86.4%) self-identified as White/Caucasian, 21.5% were women, 46% were chief residents, 28.4% completed additional postgraduate degrees, and 21.8% were fellowship trained. At time of chair appointment, 58% were professor rank, 53.5% held ED operations roles, and 32% served as vice chair. Women were more likely to be in educational (53% vs. 22%) versus operational (26% vs. 61%, p = 0.02) roles. Women obtained more advanced degrees (47% vs. 25%, p = 0.02), were awarded more nonfederal grants (median = 7 vs. 3, p = 0.04), and achieved more national committee leadership (median = 4 vs. 1, p = 0.02). There were no gender differences in fellowship training, awards, leadership training programs, publications, federal grants, or national/international lectures after adjusting for years in practice. CONCLUSION While the majority of chairs held prior leadership roles in ED operations, only one in five women chairs did, suggesting gender differences in the path to chair attainment. These differences in paths may contribute to persistent gender disparities in ED chairs and may be influenced by career path choices, implicit bias, and structural barriers.

Introduction: Women who suffer an out of hospital cardiac arrest receive bystander cardiopulmonary resuscitation (bCPR) less often than men. We sought to determine if there were differences in potential deterrents to providing CPR if the rescuer was a man or a woman. Methods: We surveyed participants via Amazon’s Mechanical Turk, a national crowdsourcing platform, to query why women receive less bCPR than men based on the sex of the rescuer. We asked participants to rank five themes previously identified. Eligible participants were ≥18 years, US residents, and correctly defined CPR. Participants were asked to rank the 5 following themes if the sex of the rescuer was unidentified sex, male, and female: 1) Rescuers are afraid to injure or hurt women; 2) Rescuers might have a misconception that women don’t suffer cardiac arrest; 3) Rescuers are afraid to be accused of sexual assault or sexual harassment; 4) Rescuers have a fear of touching women or that the touch might be inappropriate; 5) Rescuers think that women are “faking it” or being “overdramatic.” Results: In total, 576 participants were surveyed, and 520 responses were formally analyzed. The respondents were 42.3% female, 74.2% Caucasian, 10.4% African American, and 6.7% Hispanic. To determine a “consensus” ranking, a statistical model that finds the mode of the rankings was used, generating separate results for each of the categories of rescuer. This method determined that the modal ranking for respondents asked about a female rescuer was Hurt/Injure, Touch, Overdramatic, Misconception, Sexual Assault/Harassment. By contrast, when respondents were asked about a male rescuer, the modal ranking was found to be Touch, Sexual Assault/Harassment, Hurt/Injure, Misconception, Overdramatic. When the sex of the rescuer was not identified, the modal ranking was identical to that for the male rescuer question. Conclusion: When querying the public as to why women receive less-bystander CPR than men, there were differences in response based on the sex of the rescuer. Participants reported that a male rescuer would potentially be hindered by fears of accusation of sexual assault/harassment or inappropriate touch, while female rescuers would be more deterred due to fears of causing physical injury or harm.

Introduction: Understanding the development of psychological symptoms post-arrest is a major research gap. In qualitative studies, cardiac arrest survivors report being poorly equipped to face the numerous sequelae upon returning home, which could in turn exacerbate acute psychological symptoms from the initial cardiac arrest event. In this study, we examined associations between illness perceptions (i.e. cognitive and emotional appraisals of illness and recovery), readiness for discharge, and provider-patient communication with psychological symptoms in cardiac arrest survivors with good neurologic recovery. Methods: We distributed an online survey to cardiac arrest survivors who were members of the Sudden Cardiac Arrest Foundation. Survivors completed the Brief Illness Perception Questionnaire (B-IPQ), Readiness for Hospital Discharge Scale (RHDS), Questionnaire for the Quality of Provider-Patient Interactions (QQPPI), PTSD Checklist-5 (PCL-5), and Patient Health Questionnaire-4 (PHQ-4) which has anxiety and depression subscales. Three multiple regression models examined associations between B-IPQ, RHDS, and QQPPI scores with PCL-5 and PHQ-4 anxiety and depression sores, adjusted for age, sex, time since arrest, self-reported understanding of cardiac arrest and post-arrest symptoms at discharge, self-reported memory at discharge, functional status via the Lawton Instrumental Activities of Daily Living scale, pre-arrest Charlson Comorbidity Index, and income. Results: We obtained full data from 163 survivors (mean age: 50.1 years, 50.3% women, 95.5% white, mean time since arrest: 63.9 months). More threatening illness perceptions (β: .57, p < .01) and lower readiness for discharge (β: -.22, p = .01) were associated with greater posttraumatic stress symptoms. More threatening illness perceptions was associated with greater anxiety (β: .53, p < .01) and depression (β: .5, p < .01) symptoms. Conclusions: Illness perceptions and readiness for discharge were associated with psychological symptoms in cardiac arrest survivors. Future studies should examine the feasibility of in-hospital assessment of survivors’ illness perceptions, readiness for discharge, and psychological symptoms.

This 2020 International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations for advanced life support includes updates on multiple advanced life support topics addressed with 3 different types of reviews. Topics were prioritized on the basis of both recent interest within the resuscitation community and the amount of new evidence available since any previous review. Systematic reviews addressed higher-priority topics, and included double-sequential defibrillation, intravenous versus intraosseous route for drug administration during cardiac arrest, point-of-care echocardiography for intra-arrest prognostication, cardiac arrest caused by pulmonary embolism, postresuscitation oxygenation and ventilation, prophylactic antibiotics after resuscitation, postresuscitation seizure prophylaxis and treatment, and neuroprognostication. New or updated treatment recommendations on these topics are presented. Scoping reviews were conducted for anticipatory charging and monitoring of physiological parameters during cardiopulmonary resuscitation. Topics for which systematic reviews and new Consensuses on Science With Treatment Recommendations were completed since 2015 are also summarized here. All remaining topics reviewed were addressed with evidence updates to identify any new evidence and to help determine which topics should be the highest priority for systematic reviews in the next 1 to 2 years.
