Experience of African American Surrogate Decision Makers of Patients With Dementia

Dementia cases are expected to grow for African Americans and surrogate decision makers (SDMs) will have a significant role at the end of life (EOL). This qualitative exploratory case study used Cognitive Task Analysis and an integrated conceptual framework to understand the EOL decision experience of African American SDMs for patients with advanced dementia. Using a holistic multiple-case design, 8 African American SDMs were interviewed about their experiences with the decision-making process, including role acceptance, role enactment, and emotional outcomes of decision making. Thirteen themes germane to understanding the EOL decision experience of African American SDMs were identified. Findings suggest African American SDMs often lack sufficient knowledge of disease prognosis and intervention options to make informed treatment choices at EOL. In particular, African Americans extend the caregiver role to SDM for patients with dementia at EOL without being fully aware of the role and decision-making responsibilities. Surrogates lacked a general understanding of EOL options resulting in underutilization of hospice and palliative care and subsequent regret, and few interventions exist to improve the uptake of EOL care services. There is a need to develop culturally appropriate role preparation, education, and decision support to improve EOL treatment decisions and emotional adjustment of surrogates of patients with advanced dementia, which should be rendered early and throughout the illness trajectory.

Advance Care Planning for African American Caregivers of Relatives With Dementias: Cluster Randomized Controlled Trial

BACKGROUND AND OBJECTIVES

African-American family caregivers may have insufficient knowledge to make informed end-of-life (EOL) decisions for relatives with dementias. Advance Care Treatment Plan (ACT-Plan) is a community-based education intervention to enhance knowledge of dementia and associated EOL medical treatments, self-efficacy, intentions, and behavior (written EOL care plan). This study evaluated efficacy of the intervention compared to attention control.

RESEARCH DESIGN AND METHODS

In a theoretically based, 2-group, cluster randomized controlled trial, 4 similar Midwestern urban megachurches were randomized to experimental or control conditions. Each church recruited African-American caregivers, enrolling concurrent waves of 5 to 9 participants in 4 weekly 1-hour sessions (358 total: ACT-Plan n = 173, control n = 185). Dementia, cardiopulmonary resuscitation (CPR), mechanical ventilation (MV), and tube feeding (TF) treatments were discussed in ACT-Plan classes. Participants completed assessments before the initial class, after the final class (week 4), and at week 20. Repeated measures models were used to test the intervention effect on changes in outcomes across time, adjusting for covariates as needed.

RESULTS

Knowledge of CPR, MV, TF, and self-efficacy to make EOL treatment decisions increased significantly more in the ACT-Plan group at weeks 4 and 20. Knowledge of dementia also increased more in the ACT-Plan group at both points, reaching statistical significance only at week 20. Intentions to make EOL treatment decisions and actually an advance care plan were similar between treatment arms.

DISCUSSION AND IMPLICATIONS

Findings demonstrate promise for ACT-Plan to increase informed EOL treatment decisions for African American caregivers of individuals with dementias.

Advance care treatment plan (ACT-Plan) for African American family caregivers: a pilot study

Research is limited on end-of-life treatment decisions made by African American family caregivers. In a pilot study, we examined the feasibility of implementing an advance care treatment plan (ACT-Plan), a group-based education intervention, with African American dementia caregivers. Theoretically based, the ACT-Plan included strategies to enhance knowledge, self-efficacy, and behavioral skills to make end-of-life treatment plans in advance. Cardiopulmonary resuscitation, mechanical ventilation, and tube feeding were end-of-life treatments discussed in the ACT-Plan. In a four-week pre/posttest two-group design at urban adult day care centers, 68 caregivers were assigned to the ACT-Plan or attention-control health promotion conditions. Findings strongly suggest that the ACT-Plan intervention is feasible and appropriate for African American caregivers. Self-efficacy and knowledge about dementia, cardiopulmonary resuscitation, mechanical ventilation, and tube feeding increased for ACT-Plan participants but not for the attention-control. More ACT-Plan than attention-control participants developed advance care plans for demented relatives. Findings warrant a randomized efficacy trial.

Advance care plans for CPR or mechanical ventilation in patients with dementia

Early development of advance care plans is an ethical and supportive intervention providers can offer patients and families facing a dementia diagnosis.

Autopsy recruitment program for African Americans

A specialized brain autopsy recruitment program was implemented within the context of advance medical directives and end-of-life treatment decisions. The program was implemented within the framework of a larger study. The purpose of the program was to (1) improve the rate of consent for brain autopsy among African Americans diagnosed with stroke and dementia, and (2) obtain more empirical information on the underlying reasons for the low response rate (4%) in this minority group. A convenience sample of 133 patient and family caregiver pairs was selected for participation. Face-to-face, open-ended interviews were conducted to ascertain reasons for autopsy preferences and to identify respondents interested in the postmortem procedure. Preferences for brain autopsy were ascertained and individuals interested in the procedure were subsequently followed through death or over the 2 1/2 year course of the study. Brain necropsies were conducted on patients requesting the examination. Thirty-six (36) patient and family pairs consented to the procedure, 16 were indecisive and 81 refused. Factors influencing decisions included existing attitudes toward autopsy, family agreement regarding the procedure, and assurance that funeral arrangements would not be delayed. Ninety deaths and two autopsies were conducted before implementation of the specialized recruitment program, yielding a 2.22% completion rate, and 34 deaths with 10 postmortems conducted within the time frame of the recruitment study, yielding a 29% autopsy completion rate. Fisher exact test (p < 0.0001) revealed a significant difference in the proportion of autopsies completed before and after implementation of the specialized recruitment program. Findings strongly suggest that culturally sensitive recruitment programs may increase the rate of autopsy request made by African American caregivers for relatives diagnosed with dementia and stroke. To obtain a higher rate of consent than that obtained in the general population, the program must contain ethnically sensitive recruitment strategies.

Participation of African Americans in clinical research

Researchers throughout the United States have developed an increased interest in recruiting minority groups into studies. Such increased interests have been encouraged by the federal agencies that have mandated diversity in study populations. This editorial attempts to explore salient issues pertinent to the recruitment and retention of African Americans and cites culturally specific recruitment strategies that have been successfully applied by investigators. African Americans may have special concerns that may have to be addressed by the investigators prior to initiation of the study. Concerns may include the fear of being treated as a 'guinea pig' and the need for psychosocial programs. Such concerns require culturally sensitive strategies which may include trust-building and the provision of ancillary services. Although specific strategies are required to recruit and retain this special population in clinical studies, there are no guarantees that enrollment will be successful even with the inclusion of culturally sensitive mechanisms.
