Clinicians' approach to predicting post-cardiac arrest outcomes for patients enrolled in a United States clinical trial.

PURPOSE: Perceived poor prognosis can lead to withdrawal of life-sustaining therapies (WLST) in patients who might otherwise recover. We characterized clinicians' approach to post-arrest prognostication in a multicenter clinical trial. METHODS: Semi-structured interviews were conducted with clinicians who treated a comatose post-cardiac arrest patient enrolled in the Influence of Cooling Duration on Efficacy in Cardiac Arrest Patients (ICECAP) trial (NCT04217551). Two authors independently analyzed each interview using inductive and deductive coding. The clinician reported how they arrived at a prognosis for the specific patient. We summarized the frequency with which clinicians reported using objective diagnostics to formulate their prognosis, and compared the reported approaches to established guidelines. Each respondent provided demographic information and described local neuroprognostication practices. RESULTS: We interviewed 30 clinicians at 19 US hospitals. Most claimed adherence to local hospital neuroprognostication protocols (n = 19). Prognostication led to WLST for perceived poor neurological prognosis in 15/30 patients, of whom most showed inconsistencies with guidelines or trial recommendations, respectively. In 10/15 WLST cases, clinicians reported relying on multimodal testing. A prevalent theme was the use of "clinical gestalt," defined as prognosticating based on a patient's overall appearance or a subjective impression in the absence of objective data. Many clinicians (21/30) reported using clinical gestalt for initial prognostication, with 9/21 expressing high confidence initially. CONCLUSION: Clinicians in our study state they follow neuroprognostication guidelines in general but often do not do so in actual practice. They reported clinical gestalt frequently informed early, highly confident prognostic judgments, and few objective tests changed initial impressions. Subjective prognostication may undermine well-designed trials.

Institutional Review Boards' Assessment of Local Context: A Mixed Methods Study.

The nature of the review of local context by institutional review boards (IRBs) is vague. Requirements for single IRB review of multicenter trials create a need to better understand interpretation and implementation of local-context review and how to best implement such reviews centrally. We sought a pragmatic understanding of IRB local-context review by exploring stakeholders' attitudes and perceptions. Semistructured interviews with 26 IRB members and staff members, institutional officials, and investigators were integrated with 80 surveys of similar stakeholders and analyzed with qualitative theme-based text analysis and descriptive statistical analysis. Stakeholders described what they considered to be local context, the value of local-context review, and key processes used to implement review of local context in general and for emergency research conducted with an exception from informed consent. Concerns and potential advantages of centralized review of local context were expressed. Variability in perspectives suggests that local-context review is not a discrete process, which presents opportunities for defining pathways for single IRB review.

Selection of a statistical analysis method for the Glasgow Outcome Scale-Extended endpoint for estimating the probability of favorable outcome in future severe TBI clinical trials.

The Glasgow outcome scale-extended (GOS-E), an ordinal scale measure, is often selected as the endpoint for clinical trials of traumatic brain injury (TBI). Traditionally, GOS-E is analyzed as a fixed dichotomy with favorable outcome defined as GOS-E ≥ 5 and unfavorable outcome as GOS-E < 5. More recent studies have defined favorable vs unfavorable outcome utilizing a sliding dichotomy of the GOS-E that defines a favorable outcome as better than a subject's predicted prognosis at baseline. Both dichotomous approaches result in loss of statistical and clinical information. To improve on power, Yeatts et al proposed a sliding scoring of the GOS-E as the distance from the cutoff for favorable/unfavorable outcomes, and therefore used more information found in the original GOS-E to estimate the probability of favorable outcome. We used data from a published TBI trial to explore the ramifications to trial operating characteristics by analyzing the sliding scoring of the GOS-E as either dichotomous, continuous, or ordinal. We illustrated a connection between the ordinal data and time-to-event (TTE) data to allow use of Bayesian software that utilizes TTE-based modeling. The simulation results showed that the continuous method with continuity correction offers higher power and lower mean squared error for estimating the probability of favorable outcome compared to the dichotomous method, and similar power but higher precision compared to the ordinal method. Therefore, we recommended that future severe TBI clinical trials consider analyzing the sliding scoring of the GOS-E endpoint as continuous with continuity correction.

Desirability of Outcome Ranking for Status Epilepticus: A Benefit-Risk Approach to Design and Analyses of Clinical SE Trials.

Most clinical trials of treatment efficacy evaluate benefits and harms separately. Investigators generally rate the primary outcome of a trial with a binary outcome measure and consider harms separately as adverse events. This approach fails to recognize finer gradations of patient response, correlations between benefits and harms, and the overall effects on individual patients. For example, in status epilepticus trials, efficacy is often defined as the absence of clinically apparent seizures with recovery of consciousness. Such an efficacy outcome fails to recognize that some causes of status epilepticus, such as subarachnoid hemorrhage or stroke, may not be accompanied by return of consciousness, and the need to intubate a patient may be classified as treatment failure even if status was successfully terminated. The Desirability of Outcome Ranking (DOOR) method uses a different approach. The DOOR method involves comparing the experiences of trial participants in different treatment arms by the desirability of the overall patient outcome. Using status epilepticus treatment as an example, a patient who experiences successful termination of status epilepticus but with major side effects would have a less desirable outcome than a patient with treatment success and minor side effects, who in turn would have a less desirable outcome than a patient with treatment success but no side effects. This is a patient-centered approach because it considers treatment efficacy in the context of the costs borne by the patient, for example, toxicity in achieving efficacy. Thus, DOOR considers both the benefits and harms to individual patients in assessing the outcome of a clinical trial. In this article, we present the rationale for the use of DOOR, the issues involved in the development of and statistical analyses of an ordinal outcome, and an example of the potential application of the DOOR method to a clinical trial of convulsive status epilepticus.

Statistical assessment of the prognostic and the predictive value of biomarkers-A biomarker assessment framework with applications to traumatic brain injury biomarker studies.

Studies that investigate the performance of prognostic and predictive biomarkers are commonplace in medicine. Evaluating the performance of biomarkers is challenging in traumatic brain injury (TBI) and other conditions when both the time factor (i.e. time from injury to biomarker measurement) and different levels or doses of treatments are in play. Such factors need to be accounted for when assessing the biomarker's performance in relation to a clinical outcome. The Hyperbaric Oxygen in Brain Injury Treatment (HOBIT) trial, a phase II randomized control clinical trial seeks to determine the dose of hyperbaric oxygen therapy (HBOT) for treating severe TBI that has the highest likelihood of demonstrating efficacy in a phase III trial. Hyperbaric Oxygen in Brain Injury Treatment will study up to 200 participants with severe TBI. This paper discusses the statistical approaches to assess the prognostic and predictive performance of the biomarkers studied in this trial, where prognosis refers to the association between a biomarker and the clinical outcome while the predictiveness refers to the ability of the biomarker to identify patient subgroups that benefit from therapy. Analyses based on initial biomarker levels accounting for different levels of HBOT and other baseline clinical characteristics, and analyses of longitudinal changes in biomarker levels are discussed from a statistical point of view. Methods for combining biomarkers that are of complementary nature are also considered and the relevant algorithms are illustrated in detail along with an extensive simulation study that assesses the performance of the statistical methods. Even though the discussed approaches are motivated by the HOBIT trial, their applications are broader. They can be applied in studies assessing the predictiveness and prognostic ability of biomarkers in relation to a well-defined therapeutic intervention and clinical outcome.

COVID-19 convalescent plasma boosts early antibody titer and does not influence the adaptive immune response.

Multiple randomized, controlled clinical trials have yielded discordant results regarding the efficacy of convalescent plasma in outpatients, with some showing an approximately 2-fold reduction in risk and others showing no effect. We quantified binding and neutralizing antibody levels in 492 of the 511 participants from the Clinical Trial of COVID-19 Convalescent Plasma in Outpatients (C3PO) of a single unit of COVID-19 convalescent plasma (CCP) versus saline infusion. In a subset of 70 participants, peripheral blood mononuclear cells were obtained to define the evolution of B and T cell responses through day 30. Binding and neutralizing antibody responses were approximately 2-fold higher 1 hour after infusion in recipients of CCP compared with saline plus multivitamin, but levels achieved by the native immune system by day 15 were almost 10-fold higher than those seen immediately after CCP administration. Infusion of CCP did not block generation of the host antibody response or skew B or T cell phenotype or maturation. Activated CD4+ and CD8+ T cells were associated with more severe disease outcome. These data show that CCP leads to a measurable boost in anti-SARS-CoV-2 antibodies but that the boost is modest and may not be sufficient to alter disease course.

Why ketamine.

We present the rationale for testing ketamine as an add-on therapy for treating benzodiazepine refractory (established) status epilepticus. In animal studies, ketamine terminates benzodiazepine refractory status epilepticus by interfering with the pathophysiological mechanisms and is a neuroprotectant. Ketamine does not suppress respiration when used for sedation and anesthesia. A Series of reports suggest that ketamine can help terminate refractory and super refractory status epilepticus. We propose to use 1 or 3 mg/Kg ketamine intravenously based on animal-to-human conversion and pharmacokinetic studies. This paper was presented at the 8th London-Innsbruck Colloquium on Status Epilepticus and Acute Seizures held in September 2022.

What have we learned from the RAMPART and ESETT randomized controlled trials?

Lessons learned from the Rapid Anticonvulsant Medication Prior to Arrival Trial (RAMPART) and Established Status Epilepticus Treatment Trial (ESETT) trials are considered in three ways. First, by asking about the questions the trials were primarily designed to answer, then about the context of the intervention and characteristics of the patients described in secondary analyses, and finally, about what was learned about how to conduct trials in this space. The talk concludes with suggestions and a vision for how to best conduct future trials investigating status epilepticus. This paper was presented at the 8th London-Innsbruck Colloquium on Status Epilepticus and Acute Seizures held in September 2022.

The Midazolam RAMPART Study Medical Records Project: A Unique Use of Real-World Data in a Complex Collaborative Partnership to Support a New Drug Application.

INTRODUCTION: This project aimed to retrospectively obtain, review, and extract key safety data from medical records of participants enrolled in RAMPART, the NIH-supported Rapid Anticonvulsant Medication Prior to ARrival Trial of intramuscular midazolam versus intravenous lorazepam for pre-hospital treatment of status epilepticus, to support a US new drug application (NDA) for intramuscular midazolam. METHODS: A collaborative partnership was established between the NDA sponsor, the RAMPART trial lead academic institution, US government agencies, and contract research organizations to retrieve, review, and extract relevant safety data from the medical records of RAMPART participants and summarize those data to include in an NDA submitted to the US Food and Drug Administration (FDA). RESULTS: Key data in the medical records of 890 RAMPART trial participants (1020 enrollments, including 130 repeat enrollments) were reviewed and extracted into a project database. Safety events occurred in 771 (86.6%) participants, and included additional information not collected in the RAMPART trial. This database also enabled subgroup analyses based on medical history and prior/concurrent medications, building upon previous analyses according to age, sex, and race. No previously unrecognized safety patterns were identified, and no association was observed between efficacy and medical history or medication usage. CONCLUSIONS: The use of unstructured real-world retrospective medical record data can effectively support an NDA submission in place of conducting another interventional clinical trial. This retrospective medical records review and extraction of additional safety data contributed to the FDA approval of intramuscular midazolam for the pre-hospital treatment of status epilepticus in 2018. CLINICALTRIALS: GOV: NCT00809146.

An adaptive clinical trial design to identify the target dose of tenecteplase for treatment of acute pulmonary embolism.

BACKGROUND/AIMS: Fibrinolytic therapy with tenecteplase has been proposed for patients with pulmonary embolism but the optimal dose is unknown. Higher-than-necessary dosing is likely to cause excess bleeding. We designed an adaptive clinical trial to identify the minimum and assumed safest dose of tenecteplase that maintains efficacy. METHODS: We propose a Bayesian adaptive, placebo-controlled, group-sequential dose-finding trial using response-adaptive randomization to preferentially allocate subjects to the most promising doses, dual analyses strategies (continuous and dichotomized) using a gatekeeping approach to maximize clinical impact, and interim stopping rules to efficiently address competing trial objectives. The operating characteristics of the proposed design were evaluated using Monte Carlo simulation across multiple hypothetical efficacy scenarios. RESULTS: Simulation demonstrated response-adaptive randomization can preferentially allocate subjects to doses which appear to be performing well based on interim data. Interim decision-making, including the interim evaluation of both analysis strategies with gatekeeping, allows the trial to continue enrollment when success with the dichotomized analysis strategy appears sufficiently likely and to stop enrollment and declare superiority based on the continuous analysis strategy when there is little chance of ultimately declaring superiority with the dichotomized analysis. CONCLUSION: The proposed design allows evaluation of a greater number of dose levels than would be possible with a non-adaptive design and avoids the need to choose either the continuous or the dichotomized analysis strategy for the primary endpoint.

Treatment of Toxin-Related Status Epilepticus With Levetiracetam, Fosphenytoin, or Valproate in Patients Enrolled in the Established Status Epilepticus Treatment Trial.

STUDY OBJECTIVE: We describe a subset of patients with toxin-related precipitants of seizures/status epilepticus enrolled in the Established Status Epilepticus Treatment Trial (ESETT). METHODS: The ESETT was a prospective, double-blinded, adaptive trial evaluating levetiracetam, valproate, and fosphenytoin as second-line agents in benzodiazepine-refractory status epilepticus in adults and children. The primary outcome was the absence of seizures and improvement in the level of consciousness 1 hour after study drug administration. In this post hoc analysis, the safety and efficacy of second-line agents in a subset of patients with toxin-related seizures are described. RESULTS: A total of 249 adults and 229 children were enrolled in the ESETT. Toxin-related seizures occurred in 29 (11.6%) adults and 1 child (0.4%). In adults, men were more likely to have toxin-related seizures than women (25 of 145, 17.2% versus 4 of 104, 3.9%). The most common toxin-related precipitants were alcohol withdrawal and cocaine, 11(37%) of 30 patients each. Cocaine was used with other substances by most patients 10 (91%) of 11, most commonly with an opioid 7 (64%) of 11. For alcohol withdrawal-related seizures, treatment successes with levetiracetam, valproate, and fosphenytoin were 3 (100%) of 3, 3 (50%) of 6, and 1 (50%) of 2, respectively. For cocaine-related seizures, treatment success was 1 (14%) of 7 for levetiracetam, 0 (0%) of 1 for valproate, and 1 (33%) of 3 for fosphenytoin. One patient who used cocaine and an opioid received fosphenytoin and developed life-threatening hypotension. CONCLUSION: In the ESETT, approximately 1 in 10 adult patients with status epilepticus presented with a toxin-related seizure. Alcohol withdrawal and cocaine/opioid use were the most common toxin-related precipitants. Toxin-related benzodiazepine-refractory status epilepticus was successfully treated with a single dose of second-line antiseizure medication in 42% of the patients.

The Experiences and Needs of Families of Comatose Patients After Cardiac Arrest and Severe Neurotrauma: The Perspectives of National Key Stakeholders During a National Institutes of Health-Funded Workshop.

OBJECTIVES: Severe acute brain injury (SABI) from cardiac arrest and traumatic brain injury happens suddenly and unexpectedly, carrying high potential for lifelong disability with substantial prognostic uncertainty. Comprehensive assessments of family experiences and support needs after SABI are lacking. Our objective is to elicit "on-the-ground" perspectives about the experiences and needs of families of patients with SABI. DESIGN: Two-phase qualitative study of families and multidisciplinary U.S. healthcare professionals (mHCPs) with expertise in SABI: Phase 1 included semistructured interviews to generate formative findings; phase 2 entailed facilitated discussions to confirm and expand initial findings. SETTING: Phase 1: academic medical center; phase 2: virtual workshop. SUBJECTS: Phase 1 included seven family members and 12 mHCPs. Phase 2 included nationally recruited stakeholders (17 family members and 12 mHCPs). INTERVENTION: None. MEASUREMENTS AND RESULTS: We explored: 1) what are families' needs in the first 48 hours? 2) How are these needs addressed? and 3) How can hospitals better meet these needs? Qualitative analysis included inductive and deductive approaches guided by a conceptual ecological model. Four major needs were identified: 1) challenges in coping with uncertainty in early prognostication, 2) inattention to physical needs of family, 3) deficits in compassionate and consistent communication, and 4) need for engagement with families as stakeholders in improving future practices. Participants' recommendations included: 1) ways to communicate more clearly and consistently, 2) better assistance with navigating resources and access to places for families to care for themselves, and 3) opportunities for families to remain connected with their loved ones, social support networks, and the clinical team. CONCLUSIONS: Stakeholders identified novel insights regarding families' experiences during the hospitalization of comatose SABI patients and factors that can contribute to improved decision-making and physical/emotional outcomes. Interventions to address these unmet needs are promising targets to improve outcomes.

Electroencephalographic Seizures in Emergency Department Patients After Treatment for Convulsive Status Epilepticus.

PURPOSE: It is unknown how often and how early EEG is obtained in patients presenting with status epilepticus. The Established Status Epilepticus Treatment Trial enrolled patients with benzodiazepine-refractory seizures and randomized participants to fosphenytoin, levetiracetam, or valproate. The use of early EEG, including frequency of electrographic seizures, was determined in Established Status Epilepticus Treatment Trial participants. METHODS: Secondary analysis of 475 enrollments at 58 hospitals to determine the frequency of EEG performed within 24 hours of presentation. The EEG type, the prevalence of electrographic seizures, and characteristics associated with obtaining early EEG were recorded. Chi-square and Wilcoxon rank-sum tests were calculated as appropriate for univariate and bivariate comparisons. Odds ratios are reported with 95% confidence intervals. RESULTS: A total of 278 of 475 patients (58%) in the Established Status Epilepticus Treatment Trial cohort underwent EEG within 24 hours (median time to EEG: 5 hours [interquartile range: 3-10]). Electrographic seizure prevalence was 14% (95% confidence interval, 10%-19%; 39/278) in the entire cohort and 13% (95% confidence interval, 7%-21%) in the subgroup of patients meeting the primary outcome of the Established Status Epilepticus Treatment Trial (clinical treatment success within 60 minutes of randomization). Among subjects diagnosed with electrographic seizures (39), 15 (38%; 95% confidence interval, 25%-54%) had no clinical correlate on the video EEG recording. CONCLUSIONS: Electrographic seizures may occur in patients who stop seizing clinically after treatment of convulsive status epilepticus. Clinical correlates might not be present during electrographic seizures. These findings support early initiation of EEG recordings in patients suffering from convulsive status epilepticus, including those with clinical evidence of treatment success.

Early Convalescent Plasma for High-Risk Outpatients with Covid-19.

BACKGROUND: Early administration of convalescent plasma obtained from blood donors who have recovered from coronavirus disease 2019 (Covid-19) may prevent disease progression in acutely ill, high-risk patients with Covid-19. METHODS: In this randomized, multicenter, single-blind trial, we assigned patients who were being treated in an emergency department for Covid-19 symptoms to receive either one unit of convalescent plasma with a high titer of antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) or placebo. All the patients were either 50 years of age or older or had one or more risk factors for disease progression. In addition, all the patients presented to the emergency department within 7 days after symptom onset and were in stable condition for outpatient management. The primary outcome was disease progression within 15 days after randomization, which was a composite of hospital admission for any reason, seeking emergency or urgent care, or death without hospitalization. Secondary outcomes included the worst severity of illness on an 8-category ordinal scale, hospital-free days within 30 days after randomization, and death from any cause. RESULTS: A total of 511 patients were enrolled in the trial (257 in the convalescent-plasma group and 254 in the placebo group). The median age of the patients was 54 years; the median symptom duration was 4 days. In the donor plasma samples, the median titer of SARS-CoV-2 neutralizing antibodies was 1:641. Disease progression occurred in 77 patients (30.0%) in the convalescent-plasma group and in 81 patients (31.9%) in the placebo group (risk difference, 1.9 percentage points; 95% credible interval, -6.0 to 9.8; posterior probability of superiority of convalescent plasma, 0.68). Five patients in the plasma group and 1 patient in the placebo group died. Outcomes regarding worst illness severity and hospital-free days were similar in the two groups. CONCLUSIONS: The administration of Covid-19 convalescent plasma to high-risk outpatients within 1 week after the onset of symptoms of Covid-19 did not prevent disease progression.

Efficacy of Home Anticonvulsant Administration for Second-Line Status Epilepticus Treatment.

OBJECTIVE: To investigate whether receiving a second-line anticonvulsant medication that is part of a patient's home regimen influences outcomes in benzodiazepine-refractory convulsive status epilepticus. METHODS: Using the Established Status Epilepticus Treatment Trial data, allocation to a study drug included in the patient's home anticonvulsant medication regimen was compared to receipt of an alternative second-line study medication. The primary outcome was cessation of clinical seizures with improved consciousness by 60 minutes after study drug initiation. Secondary outcomes were seizure cessation adjudicated from medical records and adverse events. We performed inverse probability of treatment-weighted (IPTW) logistic regressions. RESULTS: Of 462 patients, 232 (50%) were taking 1-2 of the 3 study medications at home. The primary outcome was observed in 39/89 (44%) patients allocated to their home medication vs 76/143 (53%) allocated to a nonhome medication (IPTW odds ratio [OR] 0.66, 95% confidence interval [CI] 0.39-1.14). The adjudicated outcome occurred in 37/89 (42%) patients vs 82/143 (57%), respectively (IPTW OR 0.52, 95% CI 0.30-0.89). There was no interaction between study levetiracetam and home levetiracetam and there were no differences in adverse events. CONCLUSION: There was no difference in the primary outcome for patients who received a home medication vs nonhome medication. However, the retrospective evaluation suggested an association between receiving a nonhome medication and seizure cessation. CLASSIFICATION OF EVIDENCE: This study provides Class II evidence that for patients with refractory convulsive status epilepticus, use of a home second-line anticonvulsant compared to a nonhome anticonvulsant did not significantly affect the probability of stopping seizures.

Early Neurologic Recovery, Practice Pattern Variation, and the Risk of Endotracheal Intubation Following Established Status Epilepticus.

OBJECTIVE: To quantify the association between early neurologic recovery, practice pattern variation, and endotracheal intubation during established status epilepticus, we performed a secondary analysis within the cohort of patients enrolled in the Established Status Epilepticus Treatment Trial (ESETT). METHODS: We evaluated factors associated with the endpoint of endotracheal intubation occurring within 120 minutes of ESETT study drug initiation. We defined a blocked, stepwise multivariate regression, examining 4 phases during status epilepticus management: (1) baseline characteristics, (2) acute treatment, (3) 20-minute neurologic recovery, and (4) 60-minute recovery, including seizure cessation and improving responsiveness. RESULTS: Of 478 patients, 117 (24.5%) were intubated within 120 minutes. Among high-enrolling sites, intubation rates ranged from 4% to 32% at pediatric sites and 19% to 39% at adult sites. Baseline characteristics, including seizure precipitant, benzodiazepine dosing, and admission vital signs, provided limited discrimination for predicting intubation (area under the curve [AUC] 0.63). However, treatment at sites with an intubation rate in the highest (vs lowest) quartile strongly predicted endotracheal intubation independently of other treatment variables (adjusted odds ratio [aOR] 8.12, 95% confidence interval [CI] 3.08-21.4, model AUC 0.70). Site-specific variation was the factor most strongly associated with endotracheal intubation after adjustment for 20-minute (aOR 23.4, 95% CI 6.99-78.3, model AUC 0.88) and 60-minute (aOR 14.7, 95% CI 3.20-67.5, model AUC 0.98) neurologic recovery. CONCLUSIONS: Endotracheal intubation after established status epilepticus is strongly associated with site-specific practice pattern variation, independently of baseline characteristics, and early neurologic recovery and should not alone serve as a clinical trial endpoint in established status epilepticus.

Meeting unique requirements: Community consultation and public disclosure for research in emergency setting using exception from informed consent.

BACKGROUND: Exception from informed consent (EFIC) regulations for research in emergency settings contain unique requirements for community consultation and public disclosure. These requirements address ethical challenges intrinsic to this research context. Multiple approaches have evolved to accomplish these activities that may reflect and advance different aims. This scoping review was designed to identify areas of consensus and lingering uncertainty in the literature. METHODS: Scoping review methodology was used. Conceptual and empirical literature related to community consultation and public disclosure for EFIC research was included and identified through a structured search using Embase, HEIN Online, PubMed, and Web of Science. Data were extracted using a standardized tool with domains for major literature categories. RESULTS: Among 84 manuscripts, major domains included conceptual or policy issues, reports of community consultation processes and results, and reports of public disclosure processes and results. Areas of consensus related to community consultation included the need for a two-way exchange of information and use of multiple methods. Public acceptance of personal EFIC enrollment is commonly 64% to 85%. There is less consensus regarding how to assess attitudes, what "communities" to prioritize, and how to determine adequacy for individual projects. Core goals of public disclosure are less well developed; no metrics exist for assessing adequacy. CONCLUSIONS: Multiple methods are used to meet community consultation and public disclosure requirements. There remain no settled norms for assessing adequacy of public disclosure, and there is lingering debate about needed breadth and depth of community consultation.
