Kananeh, Mohammed F; Brady, Paul D; Mehta, Chandan B; Louchart, Lisa P; Rehman, Mohammed F; Schultz, Lonni R; Lewis, Ariane; Varelas, Panayiotis N
OBJECTIVE:To account for factors affecting family approach and consent for organ donation after brain death (BD). MATERIAL AND METHODS/METHODS:A prospective cohort study in a large, tertiary, urban hospital, where we reviewed the database of all brain-dead patients between January 2006 and December 2017 cross-matched with local organ procurement organization (OPO) records. RESULTS:Two-hundred sixty-six brain-dead patients were included (55% African Americans (AAs)). Two-hundred twenty-two were approached for donation. The reason for not approaching families was medical exclusion due to cancer or multi-organ failure. Patient demographics or religion were not associated with approaching families. Lower creatinine level was the only independent factor associated with higher approach. Consent rate for organ donation was 72.5%. Consent was significantly higher in Caucasians (89% vs 62% for AAs), younger patients (46.7 vs 52.5 years old), in patients with lower creatinine at time of death (1.7 vs 2.4 mg/dL), patients for whom apnea testing was completed (92% vs 80%) and patients with diabetes insipidus (DI) (72% vs 54%). There was no significant relationship between consent and patient gender, admission diagnosis, number of examinations or completion of a confirmatory test. In a logistic regression model, only AA race independently predicted consent for donation (odds, 95% CI, 0.27, 0.12-0.57 p < .001). In a different model, apnea test completion was an additional independent predictor (3.66, 1.28-10.5 p = .015). CONCLUSIONS:Approaching families for organ donation consent was associated with medical suitability only and not with demographic or religious characteristics. AAs were 3.7 times less likely to consent for organ donation than non-AAs. Completion of apnea testing was associated with higher consent rates, an observation that needs to be explored in future studies documenting the effect on bedside family presence during this test.

Hemorrhagic stroke and anticoagulation in COVID-19

Dogra, Siddhant; Jain, Rajan; Cao, Meng; Bilaloglu, Seda; Zagzag, David; Hochman, Sarah; Lewis, Ariane; Melmed, Kara; Hochman, Katherine; Horwitz, Leora; Galetta, Steven; Berger, Jeffrey
BACKGROUND AND PURPOSE/OBJECTIVE:Patients with the Coronavirus Disease of 2019 (COVID-19) are at increased risk for thrombotic events and mortality. Various anticoagulation regimens are now being considered for these patients. Anticoagulation is known to increase the risk for adverse bleeding events, of which intracranial hemorrhage (ICH) is one of the most feared. We present a retrospective study of 33 patients positive for COVID-19 with neuroimaging-documented ICH and examine anticoagulation use in this population. METHODS:Patients over the age of 18 with confirmed COVID-19 and radiographic evidence of ICH were included in this study. Evidence of hemorrhage was confirmed and categorized by a fellowship trained neuroradiologist. Electronic health records were analyzed for patient information including demographic data, medical history, hospital course, laboratory values, and medications. RESULTS:We identified 33 COVID-19 positive patients with ICH, mean age 61.6 years (range 37-83 years), 21.2% of whom were female. Parenchymal hemorrhages with mass effect and herniation occurred in 5 (15.2%) patients, with a 100% mortality rate. Of the remaining 28 patients with ICH, 7 (25%) had punctate hemorrhages, 17 (60.7%) had small- moderate size hemorrhages, and 4 (14.3%) had a large single site of hemorrhage without evidence of herniation. Almost all patients received either therapeutic dose anticoagulation (in 22 [66.7%] patients) or prophylactic dose (in 3 [9.1] patients) prior to ICH discovery. CONCLUSIONS:Anticoagulation therapy may be considered in patients with COVID-19 though the risk of ICH should be taken into account when developing a treatment regimen.

Discussing Goals of Care in a Pandemic: Precedent for an Unprecedented Situation

Lewis, Ariane
The COVID-19 pandemic has precipitated the need for frequent end-of-life discussions. The circumstances surrounding these conversations are quite atypical. Here, I describe one such goals-of-care discussion during the pandemic and how I relied on the precedent of prior goals-of-care discussions to guide me through an unprecedented situation.

Determination of Brain Death/Death by Neurologic Criteria in Countries in Asia and the Pacific

Lewis, Ariane; Liebman, Jordan; Bakkar, Azza; Kreiger-Benson, Elana; Kumpfbeck, Andrew; Shemie, Sam D; Sung, Gene; Torrance, Sylvia; Greer, David
BACKGROUND AND PURPOSE/OBJECTIVE:We sought to 1) identify countries in Asia and the Pacific that have protocols for the determination of brain death/death by neurologic criteria (BD/DNC) and 2) review the similarities and differences of these protocols in different countries. METHODS:Between January 2018 and April 2019, we attempted to communicate with contacts in the 57 countries in Asia and the Pacific to determine if they had official national BD/DNC protocols. We reviewed and compared the identified protocols. RESULTS:We identified contacts for 40 (70%) of the 57 countries in Asia and the Pacific, and successfully communicated with 37 of them (93% of countries with contacts identified, 65% of countries in Asia and the Pacific). We found that 24 of the 37 countries had BD/DNC protocols. Two (13%) of the 16 protocols that provided a definition of death referred to brainstem death. Kazakhstan and Israel required only 1 examination to declare BD/DNC, while 10 (71%) of the other 14 protocols required 2 examinations separated by 6-48 hours. The prerequisites, clinical examination, apnea testing procedure, and indications for/selection of ancillary tests varied. Ancillary testing was required for all determinations of BD/DNC in five (21%) countries. Thirteen (54%) of the protocols included information about the time of death, while 12 (50%) of them provided instructions about discontinuation of organ support. CONCLUSIONS:The protocols for conducting a BD/DNC determination vary markedly among countries in Asia and the Pacific. Since it is optimal to have internationally and intranationally consistent BD/DNC protocols, efforts should be made to harmonize protocols both within this region and worldwide.

Determination of death by neurologic criteria in Latin American and Caribbean countries

Lewis, Ariane; Kreiger-Benson, Elana; Kumpfbeck, Andrew; Liebman, Jordan; Bakkar, Azza; Shemie, Sam D; Sung, Gene; Torrance, Sylvia; Greer, David
OBJECTIVES/OBJECTIVE:We sought to (1) identify the countries in the Latin America/Caribbean Group of the United Nations (GRULAC) that have protocols for brain death/death by neurologic criteria (BD/DNC) and (2) review the similarities and differences between these protocols. MATERIALS AND METHODS/METHODS:Between January 2018 and April 2019, we obtained and reviewed BD/DNC protocols from countries in GRULAC. RESULTS:We communicated with contacts in 30/33 countries in GRULAC (91 % of countries) and found that 16 (53 % of countries with contacts, 48 % of Latin American/Caribbean countries) had BD/DNC protocols. Of the 13 protocols that provided a definition of death, 10 (77 %) referred to whole brain death. The number of exams/examiners, prerequisites for BD/DNC, and descriptions of the clinical assessment and apnea test were inconsistent among protocols. Although Brazil and Panama required an ancillary test, the indications for ancillary testing, and the types of accepted ancillary tests, varied by country. CONCLUSION/CONCLUSIONS:BD/DNC determination protocols in the countries in GRULAC are inconsistent. Acknowledging the fact that there are diverse cultural, legal and religious perspectives on death, and human and technological resources differ by region, we recommend that attempts be made to harmonize protocols on BD/DNC both regionally and worldwide.

Allied Muslim Healthcare Professional Perspectives on Death by Neurologic Criteria

Lewis, Ariane; Kitamura, Elizabeth; Padela, Aasim I
BACKGROUND:We sought to evaluate how Muslim allied healthcare professionals view death by neurologic criteria (DNC). METHODS:We recruited participants from two listservs of Muslim American health professionals to complete an online survey questionnaire. Survey items probed views on DNC and captured professional and religious characteristics. Comparative statistical analyses were performed after dichotomizing the sample based on religiosity, and Chi-squared, Fisher's exact tests, likelihood ratios and the Kruskal-Wallis test were used to assess differences between the two cohorts. RESULTS:There were 49 respondents (54%) in the less religious cohort and 42 (46%) in the more religious cohort. The majority of respondents (84%) believed that if the American Academy of Neurology guidelines are followed and a person is declared brain dead, they are truly dead; there was no difference on this view based on religiosity. Less than a quarter of respondents believed that outside of organ donation, mechanical ventilation, hydration, nutrition or medications should be continued after DNC; again, there was no difference based on religiosity of the sample. Importantly, half of all respondents believed families should be able to choose whether an evaluation for DNC is performed (40% of the less religious cohort and 60% of the more religious cohort, p = 0.09) and whether organ support is discontinued after DNC (49% of both cohorts, p = 1). CONCLUSIONS:Although the majority of allied Muslim healthcare professionals we surveyed believe DNC is death, half believe that families should be able to choose whether an evaluation for DNC is performed and whether organ support should be discontinued after DNC. This provides insight that can be helpful when making medical practice policy and addressing legal controversies surrounding DNC.
