Minimum Criteria for Brain Death Determination: Consensus Promotion and Chinese Practice

Brain death (BD), the irreversible cessation of function in the whole brain, is a well-known condition in most countries. The criteria and practical guidelines for brain death determination (BDD) in China were issued by the Brain Injury Evaluation Quality Control Center (BQCC) of the National Health and Family Planning Commission in 2013. Thereafter, we proposed a plan called the three-step quality control plan (three-step QCP) to ensure the safety and consistency of the clinical judgments regarding BD. By retrospectively reviewing this plan, we aimed to identify problems during its implementation and to provide suggestions for future work on quality control for BDD. Data were retrieved from the BQCC database. The characteristics and test results of physicians undergoing a BDD training course and the BD case records submitted by hospitals before and after receiving accreditation were analyzed. In the first step of the plan, the error rate for physicians undergoing the BDD paper test was highest for limb movement discrimination (26.29%); this error rate was correlated with age (per 10-year increase) (odds ratio = 1.262, 95% confidence interval 1.067-1.491, P = 0.007) but was nonsignificantly associated with sex, specialty category, professional level, and hospital level (P > 0.05). During the second step of the plan, the highest percentage of problems was associated with apnea testing (22.75%), followed by ancillary testing of BDD (16.17%). In the last step, the highest percentage of problems in the case records was associated with apnea testing (41.73%). The three-step QCP is of significant utility for ensuring accuracy and appropriateness in BDD. Simultaneously, this study provides important evidence for advancing quality control for BDD in the next stage.

Brain Death Determination and Communication: An Innovative Approach Using Simulation and Standardized Patients

ContextPalliative medicine clinicians in hospital settings are often involved in the care of patients dying in critical care settings, with a subset from brain death. Brain death is a complex concept, not only for families, but also for clinicians. There is wide variability in adhering to formalized guidelines for brain death determination. In addition, communication techniques regarding brain death determination are distinct from those used in shared decision-making. There is a need to obtain knowledge and practical skills in brain death determination, including examination and communication. Simulation can provide a low-stakes setting to practice the process of brain death determination and communication. ObjectivesDescribe a novel approach using high-fidelity simulation to teach hospice and palliative medicine fellows the practical and nuanced aspects of brain death determination and communication. Discuss the impact on fellows’ confidence and knowledge for this learning activity. Innovation/MethodsThis three-hour workshop includes a didactic session followed by a single case conducted in three parts using standardized patient encounters and high-fidelity simulation with manikin. It is delivered annually, as part of the monthly core didactic conference for all hospice and palliative medicine fellows in the four fellowship programs in our region. Outcomes/ResultsPre- and post-intervention surveys were performed assessing perceived confidence and content-related knowledge, which showed significant improvement in both areas. Comments/ConclusionSimulation is a practical and constructive method for teaching the challenging concepts and unique communication skills involved in brain death determination.

Inconsistency in Brain Death Determination Should Not Be Tolerated.

Since it was proposed in 1980, the Uniform Determination of Death Act has provided the legal basis for determination of death by neurological criteria. The act contains language that allows for acceptable medical standards to be used to determine death. Since 1995, the American Academy of Neurology has provided guidelines for brain death determination (revised in 2010), but nationwide adherence to these guidelines has been incomplete. This variability could lead to misdiagnosis and erosion of public trust in this important medical practice. Physicians must work together as a profession to push for uniformity and accuracy in death diagnosis.

An Investigation and Suggestions for the Improvement of Brain Death Determination in China.

Background:Brain death is the irreversible cessation of the function of the brain including the brainstem. In 2013, the Brain Injury Evaluation Quality Control Centre (BQCC) of the National Health and Family Planning Commission issued criteria and practical guidelines for the determination of brain death. This study aimed to evaluate whether the institutions have adopted these guidelines and to make suggestions for the improvement of the current criteria and practical guidelines for brain death determination in China.Methods:Consecutive brain death cases from 44 hospitals were evaluated for summary statistics for the following data: the performance of BQCC criteria and practical guidelines, clinical examination, apnea testing, ancillary testing, and the number of examinations as well as the waiting periods between examinations and details of who determined brain death. Data analysis was conducted from January 2013 to December 2017.Results:A total of 550 cases were obtained. All patients were determined to have deep coma and met the prerequisites for clinical testing. The performance rates of four brainstem reflex examinations (except cough reflex) ranged from 97.5% to 98.0%, and the completion rate as well as the coincidence rate were both 100.0%. The 238 cases (50.7%) completed apnea testing, and 231 cases (42.0%) had to stop apnea testing during the examination because of instability. The performance rates of the three ancillary tests, including electroencephalogram, short-latency somatosensory evoked potential, and transcranial Doppler, were 89.5%, 67.5%, and 79.5%, respectively; furthermore, the coincidence rates were 98.6%, 96.5%, and 99.5%, respectively. The combination of two ancillary tests was more accurate than one single ancillary test. A total of 401 (72.9%) cases successfully underwent two separate examinations to determine brain death with at least a 12-h waiting period. All brain death cases were determined by at least two qualified physicians.Conclusion:This study might provide suggestions for brain death determination in China.

Variability in Diagnosing Brain Death at an Academic Medical Center.

Objective. Research continues to highlight variability in hospital policy and documentation of brain death. The aim of our study was to characterize how strictly new guidelines of American Academy of Neurology (AAN) for death by neurological criteria were practiced in our hospital prior to appointment of neurointensivists. Method. This is a retrospective study of adults diagnosed as brain dead from 2011 to 2015. Descriptive statistics compared five categories: preclinical testing, neurological examination, apnea tests, ancillary test, and documentation of time of death. Strict adherence to AAN guidelines for brain death determination was determined. Result. 76 patients were included in this study. Preclinical prerequisites were fulfilled in 53.9% and complete neurological examinations were documented in 76.3%. Apnea test was completed in 39.5%. Ancillary test was completed in 29.8%. Accurate documentation of time of death occurred in 59.2%. Overall, strict adherence to current AAN guidelines for death by neurological criteria was correctly documented in 38.2%. Conclusion. Our study shows wide variability in diagnosing brain death. These findings led us to update our death by neurological criteria policy and increase awareness of brain death determination with the goal of improving our documentation following current AAN guidelines.

Update of clinical practice guidelines for brain death determination in an academic heath center.

Brain death (BD) is determined after a patient has sustained some form of a catastrophic neurologic injury that results in an irreversible loss of cerebral and brain steam function. Variability is caused by the small number of patients who progress to BD annually causing a lack of opportunity for physicians and healthcare staff to stay competent in performing the examination. The current University of Cincinnati Medical Center policy on BD had not been updated since publication of the 2010 American Academy of Neurology guidelines on this subject. The diagnosis of BD in the medical community is an acceptable medical diagnosis, but the examination is difficult to perform, and explaining this diagnosis to a family can be challenging related to the emotions involved with discussing end of life. The goal of updating the current policy was to decrease variability in testing through consistency of practice among clinicians performing the examination. An integrative review of the evidence-based literature was conducted to identify articles discussing both BD confirmation and secondary confirmatory testing. Using this integrative review, results from hospital-based chart reviews, and targeted provider surveys, a policy update was completed. The bedside medical clinicians were provided this policy with evidence-based guidelines regarding performance of the clinical examination and confirmatory testing needed to diagnose BD and then communicate this diagnosis to the family. The current hospital policy lacked two important components of any BD policy: (a) the apnea test techniques and (b) guidance regarding secondary confirmatory testing. Both components were added during revision of the policy. Implementation of the new policy occurred through computer-based training that incorporated both didactic education of the updates and a video demonstration of a BD examination. A better defined policy for determining BD is essential. In addition, the implementation and quality assurance elements of the policy are necessary for efficiency and clinical decision making. By updating the policy within the University of Cincinnati Medical Center, the clinicians have been equipped with the latest evidence to perform the clinical examination for diagnosis of BD and then appropriately communicate this diagnosis to the family.

Variability of brain death determination guidelines in leading US neurologic institutions

In accordance with the Uniform Determination of Death Act, guidelines for brain death determination are developed at an institutional level, potentially leading to variability of practice. We evaluated the differences in brain death guidelines in major US hospitals with a strong presence of neurology and neurosurgery to determine whether there was evidence of variation from the guidelines as put forth by the American Academy of Neurology (AAN). We requested the guidelines for determination of death by brain criteria from the US News and World Report top 50 neurology/neurosurgery institutions in 2006. We evaluated the guidelines for five categories of data: guideline performance, preclinical testing, clinical examination, apnea testing, and ancillary tests. We compared the guidelines directly with the AAN guidelines for consistencies/differences. There was an 82% response rate to requests. Major discrepancies were present among institutions for all five categories. Variability existed in the guidelines' requirements for performance of the evaluation, prerequisites prior to testing, specifics of the brainstem examination and apnea testing, and what types of ancillary tests could be performed, including what pitfalls or limitations might exist. Major differences exist in brain death guidelines among the leading neurologic hospitals in the Unites States. Adherence to the American Academy of Neurology guidelines is variable. If the guidelines reflect actual practice at each institution, there are substantial differences in practice which may have consequences for the determination of death and initiation of transplant procedures.

Determination of brain death in children--a medicial center experience.

We retrospectively reviewed our organ donation team's database (timeframe: 1988-2003) identifying 18 patients under 18 years old meeting criteria for the diagnosis of brain death. We emphasized the primary diagnosis, observation period, physical findings, neurological findings, and the apnea test results according to the 1987 guidelines for brain death determination. The average age at diagnosis was 13 years and 8 months old (range: 3 months-18 years; median: 16 years). Fifteen children (82%) suffered head injuries; one (6%) had hypoxic ischemic encephalopathy; one (6%) suffered intracranial hemorrhage; and one (6%) had a brain tumor. The average observation period from clinical suspicion of brain death to the brain death test was 146 hours (range: 16-1416 hours; median: 72 hours). Among the 18 patients fulfilling the criteria, brain death was declared after two successful apnea tests performed at least 4 hours apart (average: 6 hours; range: 4-18 hours). Solid organ procurement was successful in all patients (100%). Use of the guidelines for determining brain death in children is limited in Taiwan; however, we found that the previously used guidelines in Taiwan might be appropriate for children above 3 years old, although further study is necessary to determine the roles of electroencephalography and cerebral blood flow measurement in younger children.
