Life-Sustaining Treatment and Advance Care Documentation among Chinese American ICU Decedents.

CONTEXT: Despite being one of the fastest growing ethnic groups in the U.S., there exists a gap in how treatment preferences among Chinese Americans are expressed and enacted upon in inpatient settings. OBJECTIVES: To compare the rates of advance care documentation and life-sustaining treatment between Chinese American and White American ICU decedents. METHODS: In this matched retrospective decedent cohort study, we included four ICUs within a tertiary medical center located in a Chinatown neighborhood. The Chinese American cohort included adult patients during the terminal admission in the ICU with primary language identified as Chinese (Mandarin, Cantonese, Taishanese). The White American cohort was matched according to age, sex, year of death, and admitting diagnosis. RESULTS: We identified 154 decedents in each cohort. Despite similar odds on admission, Chinese American decedents had higher odds of DNR completion (OR 1.82; 95%CI 0.99-3.40) and DNI completion (OR 1.81; 95%CI, 1.07-1.57) during the terminal ICU admission. Although Chinese American decedents had similar odds of intubation (aOR 0.90; 95%CI, 0.55-1.48), a higher proportion signed a DNI after intubation (41% vs 25%). Chinese American decedents also had higher odds of CPR (aOR 2.03; 95%CI, 1.03-41.6) with three Chinese American decedents receiving CPR despite a signed DNR order (12% vs 0%). CONCLUSIONS: During terminal ICU admissions, Chinese American decedents were more likely to complete advance care documentation and to receive CPR than White American decedents. Changes in code status were more common for Chinese Americans after intubation. Further research is needed to understand these differences and identify opportunities for goal-concordant care.

Exploratory Study of Advance Care Discussions Among Chinese American and White Stage IV Cancer Patients at an American Tertiary Medical Center.

PURPOSE: Timely advance care discussions are essential components of quality care for diverse populations; however, little is known about these conversations among Chinese American cancer patients. This exploratory study describes differences in advance care discussions and planning between Chinese American and White advanced cancer patients. METHODS: We collected data for 63 Chinese American and 63 White stage IV cancer patients who died between 2013 and 2018. We compared: frequency and timing of prognosis, goals of care (GOC), and end-of-life care (EOLC) discussions in the final year of life; family inclusion in discussions; healthcare proxy (HCP) identification; do not resuscitate (DNR) order, do not intubate (DNI) order, and other advance directive (AD) completion. We did not conduct statistical tests due to the study's exploratory nature. RESULTS: Among Chinese American and White patients, respectively, 76% and 71% had prognosis, 51% and 56% had GOC, and 89% and 84% had EOLC discussions. Prognosis, GOC, and EOLC discussions were held a median of 34.0, 15.5, and 34.0 days before death among Chinese American and 17.0, 13.0, and 24.0 days before death among White patients. Documentation rates among Chinese American and White patients were 79% and 76% for DNRs, 81% and 71% for DNIs, 79% and 81% for HCPs, and 52% and 40% for other ADs. CONCLUSIONS: Findings suggest that Chinese Americans had similar rates of advance care discussions, completed conversations earlier, and had similar to higher rates of AD documentation compared to White patients. Further studies are needed to confirm our preliminary findings.

Exploratory Study Comparing End-of-Life Care Intensity between Chinese American and White Advanced Cancer Patients at an American Tertiary Medical Center.

Background: Understanding ethnic disparities in end-of-life care (EOLC) intensity is central to improving outcomes for diverse populations. Although Chinese Americans represent one of the fastest growing ethnic groups in the United States, little is known about their EOLC intensity. Objective: To explore differences in indicators of high-intensity EOLC in the final 30 days of life, place of death, and hospice utilization between Chinese American and White advanced cancer patients. Methods: In this exploratory review, we collected data on 48 Chinese American and 48 White stage IV solid tumor patients who died during 2013-2018. Indicators of high-intensity care from the final 30 days of life included ≥2 hospital, ≥1 intensive care unit (ICU), and/or ≥2 emergency department admissions; cardiopulmonary resuscitation administration and mechanical ventilation (MV); place of death; and whether patients were on hospice at death. Results: Among Chinese American and White patients, respectively, 49% and 36% died in the hospital, 15% and 7% died in the ICU, 17% and 8% received MV, and 6% and 13% had ≥1 hospital admission lasting >14 days. Seventeen percent of Chinese American and 43% of White patients died at home. Hospice enrollment was similar between groups. Seventeen percent of Chinese American and 8% of White patients died within 30 days of diagnosis. Conclusion: Results suggest that fewer Chinese Americans died at home, whereas more died in the ICU, received MV, and died within 30 days of cancer diagnosis, indicating possible disparities in EOLC. Further studies are needed to explore findings from this exploratory investigation.

How Much Volume Should Healthcare Ethics Consult Services Have?

BACKGROUND: No standard method exists to assess how many consults a healthcare ethics consultation (HCEC) service should perform. To address this, we developed a method to estimate the volume of HCEC services based on a mixed-methods approach that included a systematic review and survey data on the volume of consult services requested. METHODS: Our investigation included a systematic review of studies that reported the volume of HCEC services that were requested from 2000 to 2017, institutional surveys, and statistical analyses that estimated the volume of HCEC services that were adjusted to the size of the hospitals in the survey and to population acuity. RESULTS: We contacted the authors of 19 studies that met our inclusion criteria; 17 authors responded to the institutional survey and five provided annualized data points. We found that standard methods of reporting the volume of HCEC services led to inaccuracies in estimating the growth of HCEC services over time. To rectify this, we proposed two means to estimate volume based on either the service goals of HCEC services or hospital size and acuity. DISCUSSION: The statistical limitations of our study highlight the need to standardize the sharing and reporting of data in clinical ethics. Future work should further standardize methods of HCEC quality assessment using measures similar to those we describe.

Urethane attenuates early neuropathology of diisopropylfluorophosphate-induced status epilepticus in rats.

Seizures can be evident within minutes of exposure to an organophosphorus (OP) agent and often progress to status epilepticus (SE) resulting in a high mortality if left untreated. Effective medical countermeasures are necessary to sustain patients suffering from OP poisoning and to mitigate the ensuing brain injury. Here, the hypothesis was tested that a single subanesthetic dose of urethane prevents neuropathology measured 24 h following diisopropylfluorophosphate (DFP)-induced SE. Adult Sprague-Dawley rats were injected with DFP to induce SE. During SE rats displayed increased neuronal activity in the hippocampus and an upregulation of immediate early genes as well as pro-inflammatory mediators. In additional experiments rats were administered diazepam (10 mg/kg, ip) or urethane (0.8 g/kg, sc) 1 h after DFP-induced SE and compared to rats that experienced uninterrupted SE. Cortical electroencephalography (EEG) and power analysis strengthen the conclusion that urethane effectively terminates SE and prevents the overnight return of seizure activity. Neurodegeneration in limbic brain regions and the seizure-induced upregulation of key inflammatory mediators present 24 h after DFP-induced SE were strongly attenuated by administration of urethane. A trivial explanation for these beneficial effects, that urethane simply reactivates acetylcholinesterase, has been ruled out. These findings indicate that, by contrast to rats administered diazepam or rats that experience uninterrupted SE, the early neuropathology after SE is prevented by subanesthetic urethane, which terminates rather than interrupts, SE.

Comprehensive Quality Assessment in Clinical Ethics.

Scholars and professional organizations in bioethics describe various approaches to "quality assessment" in clinical ethics. Although much of this work represents significant contributions to the literature, it is not clear that there is a robust and shared understanding of what constitutes "quality" in clinical ethics, what activities should be measured when tracking clinical ethics work, and what metrics should be used when measuring those activities. Further, even the most robust quality assessment efforts to date are idiosyncratic, in that they represent evaluation of single activities or domains of clinical ethics activities, or a range of activities at a single hospital or healthcare system. Countering this trend, iin this article we propose a framework for moving beyond our current ways of understanding clinical ethics quality, toward comprehensive quality assessment. We first describe a way to conceptualize quality assessment as a process of measuring disparate, isolated work activities; then, we describe quality assessment in terms of tracking interconnected work activities holistically, across different levels of assessment. We conclude by inviting future efforts in quality improvement to adopt a comprehensive approach to quality assessment into their improvement practices, and offer recommendations for how the field might move in this direction.

Successful Advance Care Planning in a Rural Nursing Home.

BACKGROUND:: Advance care planning (ACP) often culminates in the completion of advance care directives (ACD), which is a written record of informed decisions specifying the type and extent of desired medical treatment. Documentation of ACD in nursing homes in the United States indicates a 60% to 70% completion rate. There are little data on the time at which ACD are completed in relation to when the resident was admitted to the nursing home facility. OBJECTIVE:: To explore the success of advanced care planning at a large, rural long-term care (LTC) facility. METHODS:: A descriptive approach, using a retrospective chart review, of 167 residents was used to examine resident completion of health-care system documents, legal documents, predisposing factors (resident demographics and psychosocial characteristics), and the actual process of ACP as defined by the rural LTC facility. RESULTS:: This nursing home utilizes a document entitled resident preference for life-sustaining treatment (RPLST). For residents who do not have formal prepared advance directive documents, the RPLST serves to define resident and family choices for resuscitation and implementation of fluids, nutrition, medications, and antibiotics. The most striking finding was the completion rate of the RPLST within 100 days of being admitted to the nursing home. CONCLUSION:: Documentation of end-of-life preferences within 10 days of admission was achieved through the incorporation of RPLST during the resident admission process.

Beneficial Outcome of Urethane Treatment Following Status Epilepticus in a Rat Organophosphorus Toxicity Model.

The efficacy of benzodiazepines to terminate electrographic status epilepticus (SE) declines the longer a patient is in SE. Therefore, alternative methods for ensuring complete block of SE and refractory SE are necessary. We compared the ability of diazepam and a subanesthetic dose of urethane to terminate prolonged SE and mitigate subsequent pathologies. Adult Sprague Dawley rats were injected with diisopropylfluorophosphate (DFP) to induce SE. Rats were administered diazepam (10 mg/kg, ip) or urethane (0.8 g/kg, s.c.) 1 h after DFP-induced SE and compared to rats that experienced uninterrupted SE. Large-amplitude and high-frequency spikes induced by DFP administration were quenched for at least 46 h in rats administered urethane 1 h after SE onset as demonstrated by cortical electroencephalography (EEG). By contrast, diazepam interrupted SE but seizures with high power in the 20- to 70-Hz band returned 6-10 h later. Urethane was more effective than diazepam at reducing hippocampal neurodegeneration, brain inflammation, gliosis and weight loss as measured on day 4 after SE. Furthermore, rats administered urethane displayed a 73% reduction in the incidence of spontaneous recurrent seizures after four to eight weeks and a 90% reduction in frequency of seizures in epileptic rats. By contrast, behavioral changes in the light/dark box, open field and a novel object recognition task were not improved by urethane. These findings indicate that in typical rodent SE models, it is the return of SE overnight, and not the initially intense 1-2 h of SE experience, that is largely responsible for neurodegeneration, accompanying inflammation, and the subsequent development of epilepsy.
