Electrocerebral Signature of Cardiac Death.

BACKGROUND: Electroencephalography (EEG) findings following cardiovascular collapse in death are uncertain. We aimed to characterize EEG changes immediately preceding and following cardiac death. METHODS: We retrospectively analyzed EEGs of patients who died from cardiac arrest while undergoing standard EEG monitoring in an intensive care unit. Patients with brain death preceding cardiac death were excluded. Three events during fatal cardiovascular failure were investigated: (1) last recorded QRS complex on electrocardiogram (QRS0), (2) cessation of cerebral blood flow (CBF0) estimated as the time that blood pressure and heart rate dropped below set thresholds, and (3) electrocerebral silence on EEG (EEG0). We evaluated EEG spectral power, coherence, and permutation entropy at these time points. RESULTS: Among 19 patients who died while undergoing EEG monitoring, seven (37%) had a comfort-measures-only status and 18 (95%) had a do-not-resuscitate status in place at the time of death. EEG0 occurred at the time of QRS0 in five patients and after QRS0 in two patients (cohort median - 2.0, interquartile range - 8.0 to 0.0), whereas EEG0 was seen at the time of CBF0 in six patients and following CBF0 in 11 patients (cohort median 2.0 min, interquartile range - 1.5 to 6.0). After CBF0, full-spectrum log power (p < 0.001) and coherence (p < 0.001) decreased on EEG, whereas delta (p = 0.007) and theta (p < 0.001) permutation entropy increased. CONCLUSIONS: Rarely may patients have transient electrocerebral activity following the last recorded QRS (less than 5 min) and estimated cessation of cerebral blood flow. These results may have implications for discussions around cardiopulmonary resuscitation and organ donation.

Meeting the Challenge of COVID-19: The Response of Two Ethics Consultation Services in New York City.

From mid-March through May 2020, New York City was the world's epicenter of the COVID-19 pandemic, and its hospitals faced an unparalleled surge of patients who were critically ill with the virus. In addition to putting an enormous strain on medical resources, the pandemic presented many ethical issues to emotionally and physically stressed clinicians and hospital administrators. Analyses of the challenges faced by the ethics consultation services of the two campuses of New York Presbyterian Hospital, and how they assisted their clinician and administrative colleagues, is the subject of the following four articles.

The COVID-19 Crisis and Clinical Ethics in New York City.

The COVID-19 pandemic that struck New York City in the spring of 2020 was a natural experiment for the clinical ethics services of NewYork-Presbyterian (NYP). Two distinct teams at NYP's flagship academic medical centers-at NYP/Columbia University Medical Center (Columbia) and NYP/Weill Cornell Medical Center (Weill Cornell)-were faced with the same pandemic and operated under the same institutional rules. Each campus used time as an heuristic to analyze our collective response. The Columbia team compares consults during the pandemic with the same period during the year prior. The Weill Cornell service describes the phases of the pandemic to depict its temporal evolution and subsequent ethical challenges. Both sites report that the predominant ethical challenges centered around end-of-life decision making, setting goals of care, and medical futility, all complicated by resource allocation questions and the ambiguity of state law under crisis standards of care. The Columbia campus saw a statistically significant increase in ethics consultations provided to Hispanic patients, perhaps reflective of the disproportionate burden of COVID-19 suffered by this demographic. While Weill Cornell and Columbia saw a surge in clinical ethics consultations, the two services assumed a more expansive role than one normally played in institutional life. Serving as intermediaries between frontline clinicians and senior hospital administrators, consultants provided critical intelligence to hospital leadership about the evolution of the pandemic, disseminated information to clinicians, and attended to the moral distress of colleagues who were asked to provide care under truly extraordinary circumstances. The COVID-19 surge in New York City revealed latent capabilities in ethics consultation that may prove useful to the broader clinical ethics community as it responds to the current pandemic and reconceptualizes its potential for future service.

Clinical Ethics Consultations during the COVID-19 Pandemic Surge at a New York City Medical Center.

The COVID-19 pandemic swept through New York City swiftly and with devastating effect. The crisis put enormous pressure on all hospital services, including the clinical ethics consultation team. This report describes the recent experience of the ethics consultants and Columbia University Irving Medical Center during the COVID-19 surge and compares the case load and characteristics to the corresponding period in 2019. By reporting this experience, we hope to supplement the growing body of COVID-19 scientific literature and provide details of the human toll the virus took on our hospitals and communities. We also aim to highlight the role of the clinical ethics consultant as well as areas of policy and law that may need to be addressed in order to be better prepared for a future public health crisis.

Practice Patterns and Ethical Considerations in the Management of Venovenous Extracorporeal Membrane Oxygenation Patients: An International Survey.

OBJECTIVES: To characterize physicians' practices and attitudes toward the initiation, limitation, and withdrawal of venovenous extracorporeal membrane oxygenation for severe respiratory failure and evaluate factors associated with these attitudes. DESIGN: Electronic, cross-sectional, scenario-based survey. SETTING: Extracorporeal membrane oxygenation centers affiliated with the Extracorporeal Life Support Organization and the International Extracorporeal Membrane Oxygenation Network. SUBJECTS: Attending-level physicians with experience managing adult patients receiving venovenous extracorporeal membrane oxygenation. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Five-hundred thirty-nine physicians in 39 countries across six continents completed the survey. Factors that influenced the decision to limit extracorporeal membrane oxygenation initiation included older patient age (46.9%), additional organ failures (37.7%), and prolonged mechanical ventilation (35.1%). Patient comorbidities (70.5%), patient's wishes (56.0%), and etiology of respiratory failure (37.7%) were factors that influenced the decision to withdraw extracorporeal membrane oxygenation. In multivariable analysis, factors associated with increased odds of withdrawing life-sustaining therapies included pulmonary fibrosis, stroke, surrogate's desire to withdraw, lack of knowledge regarding patient's or surrogate's wishes in the setting of fibrosis, not initiating extracorporeal membrane oxygenation in the baseline scenario, and respondent religiosity. Factors associated with decreased odds of withdrawal included practicing in an environment where it is not legally possible to make decisions against patient or surrogate wishes. Most respondents (90.5%) involved other physicians in treatment decisions for extracorporeal membrane oxygenation patients, whereas only 53.2%, 45.3%, and 29.5% of respondents involved surrogates, awake patients, or bedside nurses, respectively. CONCLUSIONS: Patient and physician-level factors were associated with decision-making regarding extracorporeal membrane oxygenation initiation and withdrawal, including patient prognosis and knowledge of patient or surrogate wishes. Respondents reported low rates of engaging in shared decision-making when managing patients receiving extracorporeal membrane oxygenation.

Ethnic disparities in end-of-life care after subarachnoid hemorrhage.

BACKGROUND: It is common for patients who die from subarachnoid hemorrhage to have a focus on comfort measures at the end of life. The potential role of ethnicity in end-of-life decisions after brain injury has not been extensively studied. METHODS: Patients with subarachnoid hemorrhage were prospectively followed in an observational database. Demographic information including ethnicity was collected from medical records and self-reported by patients or their family. Significant in-hospital events including do-not-resuscitate orders, comfort measures only orders (CMO; care withheld or withdrawn), and mortality were recorded prospectively. RESULTS: 1255 patients were included in our analysis: 650 (52 %) were White, 387 (31 %) Hispanic, and 218 (17 %) Black. Mortality was similar between the groups. CMO was more commonly observed in Whites (14 %) compared to either Blacks (10 %) or Hispanics (9 %) (p = 0.04). In a multivariate analysis controlling for age and Hunt-Hess grade, Hispanics were less likely to have CMO than Whites (OR, 0.6; 95 %CI, 0.4-0.9; p = 0.02). Of the 229 patients who died, 77 % of Whites had CMO compared to 54 % of Blacks and 49 % of Hispanics (p < 0.01). In a multivariate analysis, Blacks (OR, 0.3; 95 %CI, 0.2-0.7; p < 0.01) and Hispanics (OR, 0.3; 95 %CI, 0.2-0.6; p < 0.01) were less likely to die with CMO orders than Whites. CONCLUSION: After subarachnoid hemorrhage, Blacks and Hispanics are less likely to die with CMO orders than Whites. Further research to confirm and investigate the causes of these ethnic differences should be performed.

A Standardized Approach to Treatment Over Objection in Patients Lacking Decision-Making Capacity Secondary to Neurologic Disease.

Neurologic diseases, ranging from Alzheimer dementia to mass lesions in the frontal lobe, may impair decision making. When patients with neurologic disease lack decision-making capacity, but refuse treatment, should they be treated over their objection? To address this type of ethical dilemma in medical illness, Rubin and Prager developed a standardized 7-question approach: (1) How imminent is harm without intervention? (2) What is the likely severity of harm without intervention? (3) What are the risks of intervention? (4) What are the logistics of treating over objection? (5) What is the efficacy of the proposed intervention? (6) What is the likely emotional effect of a coerced intervention? (7) What is the patient's reason for refusal? We describe the application of the standardized Rubin/Prager approach as a checklist to the case of a 50-year-old woman with a large frontal lobe meningioma, who lacked capacity as a result of the meningioma, but refused surgery. This approach may be applied to similar ethical dilemmas of treatment over objection in patients lacking capacity as a result of neurologic disease.

In COVID-19 Patients Who Suffer In-Hospital Cardiac Arrest, Cardiopulmonary Resuscitation Outcomes May Be Impacted by Arrest Etiology and Local Pandemic Conditions.

OBJECTIVES: The utility and risks to providers of performing cardiopulmonary resuscitation after in-hospital cardiac arrest in COVID-19 patients have been questioned. Additionally, there are discrepancies in reported COVID-19 in-hospital cardiac arrest survival rates. We describe outcomes after cardiopulmonary resuscitation for in-hospital cardiac arrest in two COVID-19 patient cohorts. DESIGN: Retrospective cohort study. SETTING: New York-Presbyterian Hospital/Columbia University Irving Medical Center in New York, NY. PATIENTS: Those admitted with COVID-19 between March 1, 2020, and May 31, 2020, as well as between March 1, 2021, and May 31, 2021, who received resuscitation after in-hospital cardiac arrest. INTERVENTIONS: None. MEASUREMENT AND MAIN RESULTS: Among 103 patients with coronavirus disease 2019 who were resuscitated after in-hospital cardiac arrest in spring 2020, most self-identified as Hispanic/Latino or African American, 35 (34.0%) had return of spontaneous circulation for at least 20 minutes, and 15 (14.6%) survived to 30 days post-arrest. Compared with nonsurvivors, 30-day survivors experienced in-hospital cardiac arrest later (day 22 vs day 7; p = 0.008) and were more likely to have had an acute respiratory event preceding in-hospital cardiac arrest (93.3% vs 27.3%; p < 0.001). Among 30-day survivors, 11 (73.3%) survived to hospital discharge, at which point 8 (72.7%) had Cerebral Performance Category scores of 1 or 2. Among 26 COVID-19 patients resuscitated after in-hospital cardiac arrest in spring 2021, 15 (57.7%) had return of spontaneous circulation for at least 20 minutes, 3 (11.5%) survived to 30 days post in-hospital cardiac arrest, and 2 (7.7%) survived to hospital discharge, both with Cerebral Performance Category scores of 2 or less. Those who survived to 30 days post in-hospital cardiac arrest were younger (46.3 vs 67.8; p = 0.03), but otherwise there were no significant differences between groups. CONCLUSIONS: Patients with COVID-19 who received cardiopulmonary resuscitation after in-hospital cardiac arrest had low survival rates. Our findings additionally show return of spontaneous circulation rates in these patients may be impacted by hospital strain and that patients with in-hospital cardiac arrest preceded by acute respiratory events might be more likely to survive to 30 days, suggesting Advanced Cardiac Life Support efforts may be more successful in this subpopulation.

Ophthalmology and Ethics in the COVID-19 Era.

PURPOSE: The novel coronavirus, SARS-CoV-2 (COVID-19), has disrupted the practice of ophthalmology and threatens to forever alter how we care for our patients. Physicians across the country encounter unique clinical dilemmas daily. This paper presents a curated set of ethical dilemmas facing ophthalmologists both during and following the pandemic. DESIGN: Perspective. METHODS: Case presentations drawn from actual clinical scenarios were presented during a virtual ophthalmology grand rounds and discussed with the director of clinical ethics at Columbia University Irving Medical Center. RESULTS: It has become routine to expect an ophthalmologist to be involved in many levels of care for patients critically ill with COVID-19. Ophthalmology patients, even those with chronic, progressive conditions, are being triaged, and vision-saving interventions are being postponed. Four questions were applied to each scenario, allowing for ethical conclusions to be reached. The following questions were posed: what is the imminence and severity of the harm expected without intervention? What is the efficacy of the intervention under consideration? What are the risks of treatment for the patient? What are the risks of treating the patient for the health care team? CONCLUSIONS: During this pandemic and for months, perhaps years, to come, it is critical to reconsider the ethical principles underlying modern medicine and ophthalmic care as well as the ramifications of our decisions and actions.

The ethics of neurologically complicated pregnancies.

Bioethical conflicts in pregnancy are distinguished from those in other areas of medicine due to competing interests between mother and fetus because of their shared biology. Historically, prior to the advent of fetal therapy and advances in medical technology, the maternal-fetal complex was considered to be a single entity. With advances in medicine, treatment options can now be directed at both the mother and the fetus, and a duality has evolved in the maternal-fetal unit. Thus at some point during pregnancy, two individuals rather than just one are the responsibility of the physician. In determining how to properly care for the pregnant woman with a neurologic condition, therapeutic choices must take into consideration the impact a treatment will have on both the mother and the fetus. Since what benefits one may harm the other, tension results from the need to choose. This chapter will highlight ethical conflicts arising at the interface of obstetrics and neurology. We will delve into situations where difficult reproductive and therapeutic decisions must be made in pregnant women with intellectual disabilities, stroke, brain tumors, and epilepsy. The complexity of brain death in pregnancy will be analyzed, acknowledging the influence of politics, law, and religion that bears on ethical decision-making. In approaching ethical dilemmas encountered in pregnancies complicated by neurologic conditions, frameworks based on principles, virtues, care, and feminist ethics, and case precedents will be applied to facilitate ethically appropriate shared decision-making. We hope that this chapter will provide valuable guidance for providers caring for this complex obstetric population.

Ethical Considerations for Mechanical Support.

Extracorporeal life support can support patients with severe forms of cardiac and respiratory failure. Uncertainty remains about its optimal use owing in large part to its resource-intensive nature and the high acuity illness in supported patients. Specific issues include the identification of patients most likely to benefit, the appropriate duration of support when prognosis is uncertain, and what to do when patients become dependent on extracorporeal life support but no longer have hope for recovery or transplantation. Careful deliberation of ethical principles and potential dilemmas should be made when considering the use of extracorporeal life support in advanced cardiopulmonary failure.

Mandatory ethics consultation policy.

OBJECTIVE: To describe ethics consultations at a single institution that has a mandatory ethics consultation policy. PATIENTS AND METHODS: We retrospectively reviewed the medical records of all adult patients who were admitted to the intensive care unit at Columbia University Medical Center and had an ethics consultation between August 1, 2006, and July 31, 2007. All mandatory and nonmandatory ethics consultations were reviewed. Patient diagnosis, prognosis, presence of do-not-resuscitate order, presence of written advance directives, reason for the ethics consultation, and survival data were collected. The number of ethics consultations hospital-wide from January 1, 2000, to December 31, 2007, was collected. RESULTS: The total number of mandatory and nonmandatory ethics consultations requested was 168. Of these consultations, 108 (64%) were considered mandatory, and 60 (36%) were considered nonmandatory. Between January 1, 2000, and December 31, 2007, the total number of ethics consultations increased 84%. CONCLUSION: The increase in the total number of ethics consultations is interpreted as a positive outcome of the mandatory policy. The mandatory ethics consultation policy has possibly increased exposure to ethics consultant-physician interactions, increased learning for physicians, and raised awareness among physicians and nurses of potential ethics assistance.
