    Over the past decade, the Nomenclature Committee on Cell Death (NCCD) has formulated guidelines for the definition and interpretation of cell death from morphological, biochemical, and functional perspectives. Since the field continues to expand and novel mechanisms that orchestrate multiple cell death pathways are unveiled, we propose an updated classification of cell death subroutines focusing on mechanistic and essential (as opposed to correlative and dispensable) aspects of the process. As we provide molecularly oriented definitions of terms including intrinsic apoptosis, extrinsic apoptosis, mitochondrial permeability transition (MPT)-driven necrosis, necroptosis, ferroptosis, pyroptosis, parthanatos, entotic cell death, NETotic cell death, lysosome-dependent cell death, autophagy-dependent cell death, immunogenic cell death, cellular senescence, and mitotic catastrophe, we discuss the utility of neologisms that refer to highly specialized instances of these processes. The mission of the NCCD is to provide a widely accepted nomenclature on cell death in support of the continued development of the field

    Goals of Care Conversations Documented by an Embedded Emergency Department-Palliative Care Team during COVID

    Background: There has been growing interest around integrating palliative care (PC) into emergency department (ED) practice but concern about feasibility and impact. In 2020, as the COVID pandemic was escalating, our hospital's ED and PC leadership created a new service of PC clinicians embedded in the ED. Objectives: To describe the clinical work of the embedded ED-PC team, in particular what was discussed during goals of care conversations. Design: Prospective patient identification followed by retrospective electronic health record chart extraction and analysis. Settings/Subjects: Adult ED patients in an academic medical center in the United States. Measurements/Results: The embedded ED-PC team saw 159 patients, whose mean age was 77.5. Nearly all patients were admitted, 48.0% had confirmed or presumed COVID, and overall mortality was 29.1%. Of the patients seen, 58.5% had a serious illness conversation documented as part of the consult. The most common topics addressed were patient (or family) illness understanding (96%), what was most important (92%), and a clinical recommendation (91%). Clinicians provided a prognostic estimate in 57/93 (61.3%) of documented discussions. In the majority of cases where prognosis was discussed, it was described as poor. Conclusion: Specialist PC clinicians embedded in the ED can engage in high-quality goals of care conversations that have the potential to align patients' hospital trajectory with their preferences

    Morbidity and Mortality Conference in Emergency Medicine Residencies and the Culture of Safety

    Introduction: Morbidity and mortality conferences (M+M) are a traditional part of residency training and mandated by the Accreditation Counsel of Graduate Medical Education. This study’s objective was to determine the goals, structure, and the prevalence of practices that foster strong safety cultures in the M+Ms of U.S. emergency medicine (EM) residency programs. Methods: The authors conducted a national survey of U.S. EM residency program directors. The survey instrument evaluated five domains of M+M (Organization and Infrastructure; Case Finding; Case Selection; Presentation; and Follow up) based on the validated Agency for Healthcare Research & Quality Safety Culture survey. Results: There was an 80% (151/188) response rate. The primary objectives of M+M were discussing adverse outcomes (53/151, 35%), identifying systems errors (47/151, 31%) and identifying cognitive errors (26/151, 17%). Fifty-six percent (84/151) of institutions have anonymous case submission, with 10% (15/151) maintaining complete anonymity during the presentation and 21% (31/151) maintaining partial anonymity. Forty-seven percent (71/151) of programs report a formal process to follow up on systems issues identified at M+M. Forty-four percent (67/151) of programs report regular debriefing with residents who have had their cases presented. Conclusion: The structure and goals of M+Ms in EM residencies vary widely. Many programs lack features of M+M that promote a non-punitive response to error, such as anonymity. Other programs lack features that support strong safety cultures, such as following up on systems issues or reporting back to residents on improvements. Further research is warranted to determine if M+M structure is related to patient safety culture in residency programs

    The “Surprise Question” Asked of Emergency Physicians May Predict 12-Month Mortality among Older Emergency Department Patients

    BackgroundIdentification of older adults with serious illness (life expectancy less than one year) who may benefit from serious illness conversations or other palliative care interventions in the emergency department (ED) is difficult.ObjectivesTo assess the performance of the "surprise question (SQ)" asked of emergency physicians to predict 12-month mortality.DesignWe asked attending emergency physician "Would you be surprised whether this patient died in the next 12 months?" regarding patients ≄65 years old that they had cared for that shift. We prospectively obtained death records from Massachusetts Department of Health Vital Records.SettingAn urban, university-affiliated ED.MeasurementTwelve-month mortality.ResultsWe approached 38 physicians to answer the SQ, and 86% participated. The mean age of our cohort was 76 years, 51% were male, and 45% had at least one serious illness. Out of 207 patients, the physicians stated that they "would not be surprised" if the patient died in the next 12 months for 102 of the patients (49%); 44 of the 207 patients (21%) died within 12 months. The SQ demonstrated sensitivity of 77%, specificity of 56%, positive predictive value of 32%, and negative predictive value of 90%. When combined with other predictors, the model sorted the patient who lived from the patient who died correctly 72% of the time (c-statistic = 0.72).ConclusionUse of the SQ by emergency physicians may predict 12-month mortality in older ED patients and may help emergency physicians identify older adults in need of palliative care interventions
