Determination of Brain Death/Death by Neurologic Criteria: The World Brain Death Project.

IMPORTANCE: There are inconsistencies in concept, criteria, practice, and documentation of brain death/death by neurologic criteria (BD/DNC) both internationally and within countries. OBJECTIVE: To formulate a consensus statement of recommendations on determination of BD/DNC based on review of the literature and expert opinion of a large multidisciplinary, international panel. PROCESS: Relevant international professional societies were recruited to develop recommendations regarding determination of BD/DNC. Literature searches of the Cochrane, Embase, and MEDLINE databases included January 1, 1992, through April 2020 identified pertinent articles for review. Because of the lack of high-quality data from randomized clinical trials or large observational studies, recommendations were formulated based on consensus of contributors and medical societies that represented relevant disciplines, including critical care, neurology, and neurosurgery. EVIDENCE SYNTHESIS: Based on review of the literature and consensus from a large multidisciplinary, international panel, minimum clinical criteria needed to determine BD/DNC in various circumstances were developed. RECOMMENDATIONS: Prior to evaluating a patient for BD/DNC, the patient should have an established neurologic diagnosis that can lead to the complete and irreversible loss of all brain function, and conditions that may confound the clinical examination and diseases that may mimic BD/DNC should be excluded. Determination of BD/DNC can be done with a clinical examination that demonstrates coma, brainstem areflexia, and apnea. This is seen when (1) there is no evidence of arousal or awareness to maximal external stimulation, including noxious visual, auditory, and tactile stimulation; (2) pupils are fixed in a midsize or dilated position and are nonreactive to light; (3) corneal, oculocephalic, and oculovestibular reflexes are absent; (4) there is no facial movement to noxious stimulation; (5) the gag reflex is absent to bilateral posterior pharyngeal stimulation; (6) the cough reflex is absent to deep tracheal suctioning; (7) there is no brain-mediated motor response to noxious stimulation of the limbs; and (8) spontaneous respirations are not observed when apnea test targets reach pH <7.30 and Paco2 ≥60 mm Hg. If the clinical examination cannot be completed, ancillary testing may be considered with blood flow studies or electrophysiologic testing. Special consideration is needed for children, for persons receiving extracorporeal membrane oxygenation, and for those receiving therapeutic hypothermia, as well as for factors such as religious, societal, and cultural perspectives; legal requirements; and resource availability. CONCLUSIONS AND RELEVANCE: This report provides recommendations for the minimum clinical standards for determination of brain death/death by neurologic criteria in adults and children with clear guidance for various clinical circumstances. The recommendations have widespread international society endorsement and can serve to guide professional societies and countries in the revision or development of protocols and procedures for determination of brain death/death by neurologic criteria, leading to greater consistency within and between countries.

Structure, Organization, and Delivery of Critical Care in Asian ICUs.

OBJECTIVES: Despite being the epicenter of recent pandemics, little is known about critical care in Asia. Our objective was to describe the structure, organization, and delivery in Asian ICUs. DESIGN: A web-based survey with the following domains: hospital organizational characteristics, ICU organizational characteristics, staffing, procedures and therapies available in the ICU and written protocols and policies. SETTING: ICUs from 20 Asian countries from April 2013 to January 2014. Countries were divided into low-, middle-, and high-income based on the 2011 World Bank Classification. SUBJECTS: ICU directors or representatives. MEASUREMENTS AND MAIN RESULTS: Of 672 representatives, 335 (50%) responded. The average number of hospital beds was 973 (SE of the mean [SEM], 271) with 9% (SEM, 3%) being ICU beds. In the index ICUs, the average number of beds was 21 (SEM, 3), of single rooms 8 (SEM, 2), of negative-pressure rooms 3 (SEM, 1), and of board-certified intensivists 7 (SEM, 3). Most ICUs (65%) functioned as closed units. The nurse-to-patient ratio was 1:1 or 1:2 in most ICUs (84%). On multivariable analysis, single rooms were less likely in low-income countries (p = 0.01) and nonreferral hospitals (p = 0.01); negative-pressure rooms were less likely in private hospitals (p = 0.03) and low-income countries (p = 0.005); 1:1 nurse-to-patient ratio was lower in private hospitals (p = 0.005); board-certified intensivists were less common in low-income countries (p < 0.0001) and closed ICUs were less likely in private (p = 0.02) and smaller hospitals (p < 0.001). CONCLUSIONS: This survey highlights considerable variation in critical care structure, organization, and delivery in Asia, which was related to hospital funding source and size, and country income. The lack of single and negative-pressure rooms in many Asian ICUs should be addressed before any future pandemic of severe respiratory illness.

Mechanical Ventilation Discontinuation Practices in Asia: A Multinational Survey.

Rationale: There are limited data on mechanical discontinuation practices in Asia. Objectives: To document self-reported mechanical discontinuation practices and determine whether there is clinical equipoise regarding protocolized weaning among Asian Intensive Care specialists. Methods: A survey using a validated questionnaire, distributed using a snowball method to Asian Intensive Care specialists. Results: Of the 2,967 invited specialists from 20 territories, 2,074 (69.9%) took part. The majority of respondents (60.5%) were from China. Of the respondents, 42% worked in intensive care units (ICUs) where respiratory therapists were present; 78.9% used a spontaneous breathing trial as the initial weaning step; 44.3% frequently/always used pressure support (PS) alone, 53.4% intermittent spontaneous breathing trials with PS in between, and 19.8% synchronized intermittent mandatory ventilation with PS as a weaning mode. Of the respondents, 56.3% routinely stopped feeds before extubation, 71.5% generally followed a sedation protocol or guideline, and 61.8% worked in an ICU with a weaning protocol. Of these, 78.2% frequently always followed the protocol. A multivariate analysis involving a modified Poisson regression analysis showed that working in an ICU with a weaning protocol and frequently/always following it was positively associated with an upper-middle-income territory, a university-affiliated hospital, or in an ICU that employed respiratory therapists; and negatively with a low-income or lower-middle-income territory or a public hospital. There was no significant association with "in-house" intensivist at night, multidisciplinary ICU, closed ICU, or nurse-patient ratio. There was heterogeneity in agreement/disagreement with the statement, "evidence clearly supports protocolized weaning over nonprotocolized weaning." Conclusions: A substantial minority of Asian Intensive Care specialists do not wean patients in accordance with the best available evidence or current guidelines. There is clinical equipoise regarding the benefit of protocolized weaning.

Professional burnout among physicians and nurses in Asian intensive care units: a multinational survey.

PURPOSE: Professional burnout is a multidimensional syndrome comprising emotional exhaustion, depersonalization, and diminished sense of personal accomplishment, and is associated with poor staff health and decreased quality of medical care. We investigated burnout prevalence and its associated risk factors among Asian intensive care unit (ICU) physicians and nurses. METHODS: We conducted a cross-sectional survey of 159 ICUs in 16 Asian countries and regions. The main outcome measure was burnout as assessed by the Maslach Burnout Inventory-Human Services Survey. Multivariate random effects logistic regression analyses of predictors for physician and nurse burnout were performed. RESULTS: A total of 992 ICU physicians (response rate 76.5%) and 3100 ICU nurses (response rate 63.3%) were studied. Both physicians and nurses had high levels of burnout (50.3% versus 52.0%, P = 0.362). Among countries or regions, burnout rates ranged from 34.6 to 61.5%. Among physicians, religiosity (i.e. having a religious background or belief), years of working in the current department, shift work (versus no shift work) and number of stay-home night calls had a protective effect (negative association) against burnout, while work days per month had a harmful effect (positive association). Among nurses, religiosity and better work-life balance had a protective effect against burnout, while having a bachelor's degree (compared to having a non-degree qualification) had a harmful effect. CONCLUSIONS: A large proportion of Asian ICU physicians and nurses experience professional burnout. Our study results suggest that individual-level interventions could include religious/spiritual practice, and organizational-level interventions could include employing shift-based coverage, stay-home night calls, and regulating the number of work days per month.

International Nosocomial Infection Control Consortium (INICC) report, data summary of 43 countries for 2007-2012. Device-associated module.

We report the results of an International Nosocomial Infection Control Consortium (INICC) surveillance study from January 2007-December 2012 in 503 intensive care units (ICUs) in Latin America, Asia, Africa, and Europe. During the 6-year study using the Centers for Disease Control and Prevention's (CDC) U.S. National Healthcare Safety Network (NHSN) definitions for device-associated health care-associated infection (DA-HAI), we collected prospective data from 605,310 patients hospitalized in the INICC's ICUs for an aggregate of 3,338,396 days. Although device utilization in the INICC's ICUs was similar to that reported from ICUs in the U.S. in the CDC's NHSN, rates of device-associated nosocomial infection were higher in the ICUs of the INICC hospitals: the pooled rate of central line-associated bloodstream infection in the INICC's ICUs, 4.9 per 1,000 central line days, is nearly 5-fold higher than the 0.9 per 1,000 central line days reported from comparable U.S. ICUs. The overall rate of ventilator-associated pneumonia was also higher (16.8 vs 1.1 per 1,000 ventilator days) as was the rate of catheter-associated urinary tract infection (5.5 vs 1.3 per 1,000 catheter days). Frequencies of resistance of Pseudomonas isolates to amikacin (42.8% vs 10%) and imipenem (42.4% vs 26.1%) and Klebsiella pneumoniae isolates to ceftazidime (71.2% vs 28.8%) and imipenem (19.6% vs 12.8%) were also higher in the INICC's ICUs compared with the ICUs of the CDC's NHSN.
