Overcoming barriers to informed consent in neurological research: Perspectives from a national survey.

The ethical recruitment of participants with neurological disorders in clinical research requires obtaining initial and ongoing informed consent. The purpose of this study is to characterize barriers faced by research personnel in obtaining informed consent from research participants with neurological disorders and to identify strategies applied by researchers to overcome those barriers. This study was designed as a web-based survey of US researchers with an optional follow-up interview. A subset of participants who completed the survey were selected using a stratified purposeful sampling strategy and invited to participate in an in-depth qualitative interview by phone or video conference. Data were analyzed using a mixed methods approach, including content analysis of survey responses and thematic analysis of interview responses. Over 1 year, 113 survey responses were received from US research personnel directly involved in obtaining informed consent from participants in neurological research. Frequently identified barriers to informed consent included: cognitive and communication impairments (e.g. aphasia), unrealistic expectations of research participants, mistrust of medical research, time constraints, literacy barriers, lack of available social support, and practical or resource-related constraints. Strategies to enhance informed consent included: involving close others to support participant understanding of study-related information, collaborating with more experienced research personnel to facilitate training in obtaining informed consent, encouraging participants to review consent forms in advance of consent discussions, and using printed materials and visual references. Beyond conveying study-related information, researchers included in this study endorsed ethical responsibilities to support deliberation necessary to informed consent in the context of misconceptions about research, unrealistic expectations, limited understanding, mistrust, and/or pressure from close others. Findings highlight the importance of training researchers involved in obtaining informed consent in neurological research to address disease-specific challenges and to support the decision-making processes of potential research participants and their close others.

The Need for Specialized Oncology Training for Clinical Ethicists.

Numerous ethical issues are raised in cancer treatment and research. Informed consent is challenging due to complex treatment modalities and prognostic uncertainty. Busy oncology clinics limit the ability of oncologists to spend time reinforcing patient understanding and facilitating end-of-life planning. Despite these issues and the ethics consultations they generate, clinical ethicists receive little if any focused education about cancer and its treatment. As the field of clinical ethics develops standards for training, we argue that a basic knowledge of cancer should be included and offer an example of what cancer ethics training components might look like. We further suggest some specific steps to increase collaboration between clinical ethicists and oncology providers in the outpatient setting to facilitate informed consent and proactively identify ethical issues.

Building family caregiver skills using a simulation-based intervention for care of patients with cancer: protocol for a randomized controlled trial.

BACKGROUND: Family caregivers of patients with cancer undergoing radiation therapy experience significant distress and challenges related to high symptom burden and complex care demands. This is particularly true for caregivers of patients with head and neck, esophageal, anal, rectal, and lung cancers, who are often receiving combined-modality treatment and may have tracheostomy tubes, gastrostomy tubes, or colostomies/ileostomies. This study aims to evaluate a simulation-based nursing intervention to provide information, support, and training to caregivers during radiation therapy. METHODS: This randomized controlled trial will include a sample of 180 patients and their family caregivers. Caregivers assigned to the control group will receive usual care and an informational booklet from the National Cancer Institute (NCI). Those in the intervention group will receive usual care, the NCI booklet, and three meetings with a nurse interventionist during radiation treatment followed by a booster call two weeks posttreatment. Intervention sessions focus on themes consistent with the trajectory of radiation therapy: the patient experience/needs, the caregiver experience and dyad communication, and transition to survivorship. Outcomes are measured at baseline, end of treatment (T2), and 4 (T3) and 20 (T4) weeks posttreatment, with the primary outcome being caregiver anxiety at T4. DISCUSSION: This trial is innovative in its use of simulation in a psychoeducational intervention for family caregivers. The intervention is administered at point-of-care and aimed at feasibility for integration into clinical practice. Patient quality of life and healthcare utilization measures will assess how providing support and training to the caregiver may impact patient outcomes. TRIAL REGISTRATION: The trial was registered on 08/14/2019 at ClinicalTrials.gov (identifier NCT04055948 ).

Videoconference Intervention for Distance Caregivers of Patients With Cancer: A Randomized Controlled Trial.

PURPOSE: Approximately 20% of caregivers (CGs) live > 1 hour away from the patient and are considered distance caregivers (DCGs) who often report higher distress and anxiety than local CGs. The purpose of this study was to test the effectiveness of an intervention aimed at reducing anxiety and distress in DCGs of patients with cancer. METHODS: This randomized controlled trial enrolled DCGs of patients with all cancer types who were being seen monthly by oncologists in outpatient clinics. There were three arms of the intervention delivered over a 4-month period: arm 1 (a) received 4 monthly videoconference-tailored coaching sessions with an advanced practice nurse or social worker focused on information and support, (b) participated in patient's appointments with the oncologist via videoconference over the 4-month study period, and (c) had access to a website designed for DCGs. Arm 2 did not receive the coaching sessions but received the other two components, and arm 3 received access to the DCG website only. RESULTS: There were 302 DCGs who provided pre- and postintervention data. There were significant anxiety by group (P = .028 and r = 0.16) and distress by group interactions (P = .014 and r = 0.17). Arm 1 had the greatest percentage of DCGs who demonstrated improvement in anxiety (18.6%) and distress (25.2%). CONCLUSION: Coaching and use of videoconference technology (to join the DCG into the patient-oncologist office visit) were effective in reducing both anxiety and distress for DCGs. These components could be considered for local CGs who-with COVID-19-are unable to accompany the patient to oncologist visits.

Understanding of Health-related Decision-making Terminology Among Cancer Caregivers.

Research on understanding health-related decision-making terminology among family caregivers of adults living with advanced cancer is lacking. The purpose of this study was to examine interpretations of the meaning of health-related decision-making terminology such as quality-of-life and end-of-life among caregivers of adults living with advanced cancer as a basis for improved understanding of caregiver decision support needs. Interviews were conducted with a purposive sub-sample of 10 caregivers of adults diagnosed with advanced cancer who completed a longitudinal, descriptive study (NRO14856) of factors influencing cancer care decisions. Audio transcripts were analyzed using qualitative descriptive methods. Caregivers described interpretations of the meaning and process of decision-making and decision-related distress. Caregivers were uncertain about the meaning of end-of-life-related terminology, and a placed high value on quality-of-life and faith/spirituality in the decision-making process. Improvements in information and decision support interventions are needed to better support caregivers and subsequently patients towards informed cancer care decisions.

Association between strong patient-oncologist agreement regarding goals of care and aggressive care at end-of-life for patients with advanced cancer.

INTRODUCTION: The ability of oncologists to understand patients' goals of care is recognized as a key component of quality care. The purpose of this study is to examine the influence of patient-oncologist agreement regarding goals of care upon aggressive care at end of life (EOL) for patients with advanced cancer. METHODS: Patients with advanced cancer and their oncologists were interviewed at study enrollment and every 3 months thereafter until patient death or end of the study period (15 months). A 100-point visual analogue scale was used to represent goals of care, with quality of life (scored as 0) and survival (scored as 100) as anchors. Strong goal of care agreement for survival was defined as oncologist and patient dyadic goal of care scores that fell between 70 and 100 (100 = highest goal for survival) and for comfort, dyadic goal of care values that fell between 0 and 30 (0 = high goal for comfort). RESULTS: Two hundred and six patients and eleven oncologists provided data. At the last interview prior to death, 23.3% of dyads had strong goal of care agreement for either survival (8.3%) or comfort (15%) and 76.7% had no strong agreement. There was a significant association between aggressive care use and categories of dyadic agreement regarding goals of care (p = 0.024, Cramer's V = 0.15). CONCLUSIONS: A large percentage of oncologists did not understand their patients' EOL goals of care. While aggressive care aligned with categories of dyadic agreement for goals of care, high rates of aggressive care were reported.

Making Medical Decisions for Incapacitated Patients Without Proxies: Part II.

In the United States, there is no consensus about who should make decisions in acute but non-emergent situations for incapacitated patients who lack surrogates. For more than a decade, our academic medical center has utilized community volunteers from the hospital ethics committee to engage in shared decision-making with the medical providers for these patients. In order to add a different point of view and minimize conflict of interest, the volunteers are non-clinicians who are not employed by the hospital. Using case examples and interviews with the community members, this paper describes how the protocol has translated into practice over the years since its inception. Members reported comfort with the role as well as satisfaction with the thoroughness of their discussions with the medical team. They acknowledged feelings of moral uncertainty, but expressed confidence in the process. Questions raised by the experience are discussed. Overall, the protocol has provided oversight, transparency, and protection from conflict of interest to the decision-making process for this vulnerable patient population.

Making Medical Decisions for Incapacitated Patients Without Proxies: Part I.

To date no one has identified or described the population of incapacitated patients being treated in an inpatient setting who lack proxy decision-makers. Nor, despite repeated calls for protocols to be developed for decision-making, has any institution reported on the utilization of such a protocol. In 2005, our urban tertiary care hospital instituted a protocol utilizing community members of the ethics committee to meet with the medical providers and engage in shared decision-making for patients without proxies (PWPs). We conducted a retrospective chart review and in this paper describe nearly 200 patients who were identified and treated according to the protocol over a 12 year period. After an aggressive search, family members were located for a surprising number of patients, leaving 80 patients who needed decisions to be made utilizing the PWP committee. We review the decisions required, the results of the shared decision-making meetings, and the patient outcomes. Our experience has shown that a protocol involving community volunteers to make decisions for PWPs in a timely manner is feasible and ethically defensible. The protocol has been accepted by physicians and utilized with increasing frequency. Because it was possible to gather at least minimal information on most patients, a standard of "informed best interest" was used to make decisions. PWP committee recommendations varied, but in all cases agreement was reached with the attending physicians.

Closer: A videoconference intervention for distance caregivers of cancer patients.

Distance caregivers (DCGs) represent a growing demographic. The emotional burden of caregiving for a family member with cancer is amplified by the logistical challenges of providing support from afar. DCGs feel higher levels of distress, anxiety, and depression compared with local caregivers. Videoconference technology may alleviate both the emotional and practical burdens faced by DCGs. This is an ongoing randomized controlled trial in 32 outpatient ambulatory clinics at a large, urban, comprehensive cancer center. To date, 332 patient-DCG dyads have been enrolled. DCGs must have internet access and have been identified by the patient as a source of support. The intervention period is 4 months. DCGs are randomized to one of three arms: DCGs in Arm 1 receive four coaching sessions with an advanced practice nurse or social worker and four videoconference appointments during the oncologist-patient office visit. DCGs in Arm 2 participate in four videoconference appointments with the oncologist and patient, and Arm 3 is the control group, which receives access to information through a website. Primary outcome variables are DCG distress, anxiety, depression, burden, self-efficacy, and emotional support. These data are collected electronically at baseline, 4 months, and 6 months. Patient distress, anxiety, and depression are also assessed at these same intervals using brief in-person interviews. The change in each of the DCG outcomes over time will be examined by a repeated measures analysis of covariance.

Videoconferencing Empowers Distance Caregivers to Be More Involved in Care.

Distance caregiving is a relatively new phenomenon associated with today's increasingly mobile society. Distance caregivers (DCGs)-those unable to attend a family member's oncology appointments due to distance-often miss out on supportive services offered to the patient and local family and must rely on secondhand information to keep track of the patient's plan of care. The Frances Payne Bolton School of Nursing at Case Western Reserve University in Cleveland, Ohio, is testing a program to address the needs of this unique demographic by incorporating videoconferencing into patient visits.

When slippery slope arguments miss the mark: a lesson from one against physician-assisted death.

In 1989, Susan Wolf convincingly warned of a troublesome consequence that should discourage any movement in American society towards physician-assisted death-a legal backlash against the gains made for limiting life-sustaining treatment. The authors demonstrate that this dire consequence did not come to pass. As physician-assisted suicide gains a foothold in USA and elsewhere, many other slippery slope arguments are being put forward. Although many of these speculations should be taken seriously, they do not justify halting the new practice. Instead, our courts, regulatory agencies, journalists, professional organisations and researchers should carefully monitor and study it as it unfolds, allowing continuous improvement just as our society has done in implementing the practice of limiting life-sustaining treatment.

Suspended animation-like state protects mice from lethal hypoxia.

Joseph Priestley observed the high burn rate of candles in pure oxygen and wondered if people would "live out too fast" if we were in the same environment. We hypothesize that sulfide, a natural reducer of oxygen that is made in many cell types, acts as a buffer to prevent unrestricted oxygen consumption. To test this, we administered sulfide in the form of hydrogen sulfide (H2S) to mice (Mus musculus). As we have previously shown, H2S decreases the metabolic rate of mice by approximately 90% and induces a suspended animation-like state. Mice cannot survive for longer than 20 min when exposed to 5% oxygen. However, if mice are first put into a suspended animation-like state by a 20-min pretreatment with H2S and then are exposed to low oxygen, they can survive for more than 6.5 h in 5% oxygen with no apparent detrimental effects. In addition, if mice are exposed to a 20-min pretreatment with H2S followed by 1 h at 5% oxygen, they can then survive for several hours at oxygen tensions as low as 3%. We hypothesize that prior exposure to H2S reduces oxygen demand, therefore making it possible for the mice to survive with low oxygen supply. These results suggest that H2S may be useful to prevent damage associated with hypoxia.

H2S induces a suspended animation-like state in mice.

Mammals normally maintain their core body temperature (CBT) despite changes in environmental temperature. Exceptions to this norm include suspended animation-like states such as hibernation, torpor, and estivation. These states are all characterized by marked decreases in metabolic rate, followed by a loss of homeothermic control in which the animal's CBT approaches that of the environment. We report that hydrogen sulfide can induce a suspended animation-like state in a nonhibernating species, the house mouse (Mus musculus). This state is readily reversible and does not appear to harm the animal. This suggests the possibility of inducing suspended animation-like states for medical applications.

Highly pyrimethamine-resistant alleles of dihydrofolate reductase in isolates of Plasmodium falciparum from Tanzania.

In 2000 we used a sensitive technique to examine 9 isolates from malaria patients in Muheza, Tanzania who had failed treatment with sulfadoxine-pyrimethamine (SP). Three isolates carried, at low levels, the leucine to isoleucine change at amino acid 164 that is associated with clinical failure of SP. Numerous other highly resistant alleles were also observed.
