Research Priorities of Individuals and Caregivers With Lewy Body Dementia: A Web-based Survey

INTRODUCTION

Lewy body dementia (LBD) is common, yet under-recognized and under-researched. To plan studies with the highest impact, engagement of the community personally affected by these conditions is essential.

METHODS

A web-based survey of people living with LBD and current and former caregivers of people with LBD queried research priorities through forced ranking and exploration of burden of LBD symptoms. Specific caregiving needs in LBD and perceptions of research participation were also investigated.

RESULTS

Between April 7, 2021 and July 1, 2021, 984 responses were recorded. Top research priorities included disease-modifying therapies and improved disease detection and staging. People with LBD were interested in pathophysiology and more bothered by motor symptoms; caregivers were interested in risk factors and symptomatic therapies and more bothered by neuropsychiatric symptoms. Few available LBD treatments and resources were rated as helpful, and many valuable services were never received. Previous participation in LBD research was infrequent, but interest was high.

DISCUSSION

People with LBD and caregivers highlighted the need for research across all aspects of LBD, from pathophysiology and disease modification to prognosis, education, symptomatic treatments, and caregiver support. Funders should increase support for all aspects of LBD research to target the many needs identified by individuals and families living with LBD.

Informal caregiver experiences at the end-of-life of individuals living with dementia with Lewy bodies: An interview study

Individuals with dementia with Lewy bodies (DLB) commonly die from dementia-related causes, but little is known regarding caregiver experiences during the end-of-life period in DLB. This reflects a critical knowledge gap given the high frequency of informal caregiving for individuals with dementia, high caregiver burden in DLB, and the fact that most individuals with DLB die from this disease. Investigators conducted telephone interviews with family members of individuals who died with DLB in the last 5 years. Investigators used a qualitative descriptive approach to analyze interview transcripts. Participants included 15 children, 13 spouses, and 2 other family members. Interviews averaged 31 min. Major themes included caregivers as the main drivers of care for individuals with DLB throughout the disease course and at the end of life, the impact of DLB features (e.g., fluctuations, hallucinations, and delusions) on end-of-life experiences, experiences relating to the caregiving role, death and post-death experiences, and supports employed by caregivers in the end-of-life period. End-of-life experiences for caregivers of individuals with DLB built on the accumulated burden of the disease course, where caregivers were often responsible for driving DLB care-from making the diagnosis to educating healthcare professionals and double-checking medical decisions. While some end-of-life experiences were consistent with those described in dementia palliative care more generally (e.g., financial stresses, poor sleep, being overwhelmed, and needing increased education and support), many DLB features specifically affected end-of-life caregiver experiences, such as the presence of delusions. Improving caregiver experiences at the end of life in DLB will require improved diagnosis and care for individuals with DLB throughout the disease course and also better strategies for treating behavioral symptoms. More research is needed regarding drivers of quality end-of-life experiences for individuals with DLB and their families and how drivers and strategies may differ between dementias.

Caregiver-Reported Barriers to Quality End-of-Life Care in Dementia With Lewy Bodies: A Qualitative Analysis

OBJECTIVE

This study investigated barriers to quality end-of-life (EOL) care in the context of dementia with Lewy bodies (DLB), one of the most common degenerative dementias in the United States.

METHODS

The study consisted of telephone interviews with caregivers and family members of individuals who died with DLB in the last 5 years. Interviews used a semi-structured questionnaire. Investigators employed a qualitative descriptive approach to analyze interview transcripts and identify common barriers to quality EOL care.

RESULTS

Thirty participants completed interviews. Reported barriers to quality EOL experiences in DLB pertained to the DLB diagnosis itself and factors relating to the US health-care system, facilities, hospice, and health-care providers (physicians and staff). Commonly reported barriers included lack of recognition and knowledge of DLB, lack of education regarding what to expect, poor coordination of care and communication across health-care teams and circumstances, and difficulty accessing health-care resources including skilled nursing facility placement and hospice.

CONCLUSION

Many identified themes were consistent with published barriers to quality EOL care in dementia. However, DLB-specific EOL considerations included diagnostic challenges, lack of knowledge regarding DLB and resultant prescribing errors, difficulty accessing resources due to behavioral changes in DLB, and waiting to meet Medicare dementia hospice guidelines. Improving EOL experiences in DLB will require a multifaceted approach, starting with improving DLB recognition and provider knowledge. More research is needed to improve recognition of EOL in DLB and factors that drive quality EOL experiences.

End-of-life experiences in dementia with Lewy bodies: Qualitative interviews with former caregivers

BACKGROUND

Dementia caregivers describe knowing what to expect as an unmet need and many are unaware that dementia can be a terminal condition. Dementia with Lewy bodies (DLB) is a common neurodegenerative dementia with unique features which may affect the end of life (EOL). Given the paucity of data on EOL experiences in dementia and unique aspects of DLB affecting EOL, we investigated EOL experiences as reported by caregivers of individuals with DLB.

METHOD

We conducted telephone interviews with caregivers and family members of individuals who died with DLB in the last 5 years using a semi-structured questionnaire to identify and describe EOL experiences. We used a qualitative descriptive approach to analyze interview transcripts and identify common themes.

RESULTS

Thirty individuals participated in interviews. Key themes included lack of knowledge regarding what to expect, end-of-life time course (including end-of-life symptoms, declines after hospitalization and falls, and varied EOL trajectories), advance care planning, lack of family understanding, hospice, views regarding right-to-die, medications at the end of life, approaching end of life, the death experience, and activities that enhanced end of life. Lack of communication between health care teams and families and difficulty predicting death timing were two frequently expressed challenges.

CONCLUSIONS

Study results emphasize the need for improved EOL counseling in DLB, recognition of EOL symptoms, earlier hospice involvement, tailoring EOL care to DLB-specific needs, and clinician-family communication. Suggestions for patient and family education are provided. Further research should confirm predictors of approaching EOL in DLB, identify strategies to improve physician recognition of EOL, and develop tools to aid communication and quality EOL care.
