Association between hospice care and psychological outcomes in Alzheimer's spousal caregivers

Biomarkers and Risk Assessment of Alzheimer's Disease in Low- and Middle-Income Countries

Dementia is a chronic syndrome which is common among the elderly and is associated with significant morbidity and mortality for patients and their caregivers. Alzheimer's disease (AD), the most common form of clinical dementia, is biologically characterized by the deposition of amyloid-β plaques and neurofibrillary tangles in the brain. The onset of AD begins decades before manifestation of symptoms and clinical diagnosis, underlining the need to shift from clinical diagnosis of AD to a more objective diagnosis using biomarkers. Having performed a literature search of original articles and reviews on PubMed and Google Scholar, we present this review detailing the existing biomarkers and risk assessment tools for AD. The prevalence of dementia in low- and middle-income countries (LMICs) is predicted to increase over the next couple of years. Thus, we aimed to identify potential biomarkers that may be appropriate for use in LMICs, considering the following factors: sensitivity, specificity, invasiveness, and affordability of the biomarkers. We also explored risk assessment tools and the potential use of artificial intelligence/machine learning solutions for diagnosing, assessing risks, and monitoring the progression of AD in low-resource settings. Routine use of AD biomarkers has yet to gain sufficient ground in clinical settings. Therefore, clinical diagnosis of AD will remain the mainstay in LMICs for the foreseeable future. Efforts should be made towards the development of low-cost, easily administered risk assessment tools to identify individuals who are at risk of AD in the population. We recommend that stakeholders invest in education, research and development targeted towards effective risk assessment and management.

Evaluation of Federal Policy Changes to the Hospice Benefit and Use of Hospice for Persons With ADRD

Question

Did hospice use for persons with Alzheimer disease and related dementias (ADRD) change between 2008 and 2019 in conjunction with Medicare policy changes that aimed to reduce long hospice stays?

Findings

In this cross-sectional study of Medicare claims data from 11 124 992 unique hospice episodes, there were immediate declines in the share of patients receiving hospice care with ADRD and a slower growth in use of hospice care among patients with ADRD after implementation of the US Improving Medicare Post-Acute Care Transformation Act and the 2-tier payment system compared with prepolicy trends.

Meaning

The study results suggest that reduced utilization of hospice by patients with ADRD following these policy changes may be negatively associated with end-of-life experience and outcomes for persons with ADRD.

Importance

Hospice is an important end-of-life service for patients with Alzheimer disease and related dementias (ADRD).

Objective

To determine whether hospice use among patients with ADRD changed in association with recent policies aimed at reducing hospice misuse and long hospice stays, an outcome that may have disproportionately affected patients with ADRD because of their lengthy end-of-life trajectories.

Design, Setting, and Participants

This observational cross-sectional study used Medicare hospice claims data from Medicare hospice episodes of care beginning between July 2008 and December 2019 among Medicare hospice beneficiaries 65 years or older at time of enrollment. Data analysis was conducted between September 2019 and June 2021.

Exposures

The 2014 Improving Medicare Post-Acute Care Transformation (IMPACT) Act, which systematized audits of hospices with a high proportion of long stays, and the 2016 2-tier payment system, which reduced daily reimbursement rates after 60 days.

Main Outcomes and Measures

Monthly percentage of (1) new patient enrollees, (2) patient census, and (3) care days provided to patients with an ADRD code.

Results

The sample included 11 124 992 unique hospice episodes between 2008 and 2019; mean (SD) patient enrollment age ranged from 82.0 (8.2) years to 82.8 (8.7) years; the percentage of male patients ranged from 40.5% to 42.7%, and the percentage of Black, Hispanic, and White patients ranged from 7.7% to 8.2%, 1.5% to 2.0%, and 86.2% to 88.8%, respectively, across years. The percentage of new enrollees with an ADRD code dropped significantly during the months of IMPACT passage (−1.42 percentage points; 95% CI, −2.13 to −0.71) and implementation (−1.98 percentage points; 95% CI, −2.70 to −1.26) but rose again during the following months. While no significant changes were observed at the time of 2-tier payment implementation (0.15 percentage points; 95% CI, −0.21 to 0.51), the average rate of increase during the subsequent period was slower (0.01 percentage points per month; 95% CI, 0-0.02) than in earlier periods (0.05; 95% CI, 0.04-0.06 during the baseline period). Similar patterns were observed for the percentage of patient census and care days provided to patients with an ADRD code.

Conclusions and Relevance

The results of this cross-sectional study of Medicare hospice claims data suggested that recent Medicare policies were associated with immediate and lasting reductions in the share of patients receiving hospice care with an ADRD code compared with expectations from preimplementation trends. Future research should examine mechanisms through which hospices enacted change and consequences for quality of care.

Idosos em cuidados paliativos

Introdução: Diante do maior número de idosos no país, destaca-se a importância de diálogos voltados ao cenário de fim de vida. O Brasil foi o 42o no Death Quality Index de 2015, o que reflete a necessidade de melhorias na qualidade de morte associadas à instituição de política nacional de cuidados paliativos (CP) forte e efetiva. Objetivo: Realizar revisão integrativa sobre como a aplicação dos CP no idoso auxilia o parceiro/cônjuge no processo de terminalidade, em comparação aos de pacientes que não recebem CP. Métodos: Foi feita uma revisão integrativa com os artigos das bases de dados PubMed e Biblioteca Virtual em Saúde no período de 2000 a agosto de 2020. Resultados: Os principais resultados demonstraram que os cuidadores que utilizaram CP relataram sintomas mais baixos de depressão pós-morte e ansiedade em comparação com aqueles que não usaram CP. Os determinantes mais importantes da satisfação com o CP foram a ajuda profissional disponível e o atendimento de natureza holística, que englobou a família e observou os cuidados físicos, psicológicos, espirituais e psicossociais dos familiares. Conclusões: Conforme apresentado, muitas vezes, cabe ao parceiro/cônjuge realizar o papel de cuidador. Seu isolamento e dedicação exclusiva podem desencadear sentimentos depressivos e excesso de responsabilidades, sobretudo quando não há suporte. Nesta pesquisa, observou-se que o uso do CP pode propiciar melhor entendimento do processo evolutivo da doença, desde o início até o luto.

Factors Associated With Family Caregiver Burden of Home-Dwelling Patients With Advanced Dementia

OBJECTIVES

To realize patients' preferences for home death, this study aimed to identify factors associated with family caregiver burden of home-dwelling patients with advanced dementia and examine its relationship with end-of-life care treatment decisions.

DESIGN

A prospective cohort study.

SETTING AND PARTICIPANTS

Patient-family caregiver dyads enrolled in a home-based palliative care program for patients with advanced dementia, with family caregiver burden assessed using the Zarit Burden Interview (ZBI) on enrolment, were included.

METHODS

Independent variables included sociodemographic data, patients' clinical phase, symptom severity, quality of life, informal paid help availability, and community resources utilized. Dependent variable was continuous ZBI scores and ZBI scores dichotomized into <24 and ≥24 for predicting depression risk. Place of death and interventions received 2 weeks before death were also collected. Data were analyzed using multivariate linear and logistic regression.

RESULTS

From October 2014 to December 2020, a total of 377 family caregivers were assessed with ZBI. Median score was 25 (IQR 15-36), and 54.4% of them were at risk of depression. Younger family caregivers had higher ZBI scores (β = -0.22, 95% CI -0.38, -0.07), with the depression risk doubling for family caregivers aged <60 years (OR 2.13, 95% CI 1.33, 3.43). Absence of informal paid help also increased the ZBI scores (β = -9.04, 95% CI -14.86, -3.22) and depression risk (OR 2.50, 95% CI 1.03, 6.09). In addition, caregivers' ZBI scores increased with patients' neuropsychiatric symptom severity (β = 0.49, 95% CI 0.08, 0.89), and caregivers of clinically unstable patients had a higher depression risk (OR 1.80, 95% CI 1.03, 3.12). Baseline caregiver burden was not associated with treatment decisions made at the end of life.

CONCLUSIONS AND IMPLICATIONS

Younger family caregivers caring for clinically unstable patients with severe neuropsychiatric symptoms experienced greater burden without informal paid help. For end-of-life care at home in advanced dementia to be tenable, relevant national agencies and stakeholders are recommended to work collectively to support family caregivers holistically.

The lived experience of spiritual well-being amongst family caregivers of persons with dementia on palliative care

Family caregivers of persons with dementia are known to experience caregiver burden, anxiety, and social isolation. Spiritual well-being may help ameliorate these characteristics. The meaning of this phenomenon, though, is not known to have been explored previously within this caregiving population. This hermeneutic phenomenological study examined the lived experiences of spiritual well-being in 10 family caregivers. The analysis of semi-structured interviews revealed 5 prominent themes: being connected, strength, presence, hardships, and duty. Phenomenological writing revealed the essence of spiritual well-being in the context of this study. This understanding will help nurses appreciate the importance some family caregivers place on spirituality and recognize when a family caregiver may benefit from a spiritual guidance referral. Further research is recommended to examine associations between spiritual well-being and burden, depression, and social isolation in caregivers of persons with dementia at different stages of receiving palliative care.

Advance care planning and anticipatory decision making in patients with Alzheimer disease

Early advance care planning and anticipatory decision making in the Alzheimer disease (AD) trajectory is a strategy NPs can incorporate to improve managing uncertainty around common decisions. This article explores decisions patients and caregivers face along the AD trajectory and provides resources for patients, caregivers, and NPs.

A cross-sectional study of family caregiver burden and psychological distress linked to frailty and functional dependency of a relative with advanced dementia

Psychological health of caregivers of people with dementia is a major public concern. This study sought to determine the relationship between caregiver burden, psychological distress, frailty and functional dependency of a relative with advanced dementia. Persons with dementia and their caregivers (102 dyads) participated in this Portuguese community based cross-sectional study. Data were collected using the Clinical Dementia Rating Scale, a sociodemographic questionnaire, the Zarit Burden Interview, the Brief Symptoms Inventory and the Edmonton Frail Scale. Alzheimer's disease was the most common type of dementia among the recipients of care, who showed moderate (42.2%) to severe (52.9%) dementia. Among them 35.3% exhibited moderate and 45.1% severe frailty. Family caregivers reported moderate (76.5%) to severe burden (18.6%). Psychological distress was very high among family caregivers. Results show that people with dementia exhibited moderate (35.3%) or severe frailty (45.1%) and that a severe frailty was found in people with moderate dementia. A one-way ANOVA was conducted between the Global Severity Index and some sociodemographic variables. ANOVA reached p < .01 for employment status of the caregiver, assistance and professional support, and psychiatric history; and p = 0.01 for caregiver age and years of caregiving. Although caregivers reported benefit from the supportive approach offered by the multidisciplinary home care team, high levels of distress and associated burden were found, which might decrease their capacity to care for the person with dementia and their own health and well-being.

The experience of psychological distress in family caregivers of people with dementia: A cross-sectional study

PURPOSE

To evaluate the degree of psychological distress in family caregivers of people with dementia.

DESIGN AND METHODS

A nonprobabilistic sample of 54 dyads (people with dementia and family caregivers) was recruited. A sociodemographic questionnaire, the Brief Symptom Inventory (BSI), and the Barthel Index were used for data collection.

FINDINGS

About half of the caregivers had significant levels of psychological distress. Caregivers showed high scores in some BSI dimensions: somatization, obsessive-compulsion, interpersonal sensitivity, anxiety, and paranoid ideation.

PRACTICE IMPLICATIONS

Alleviating the caregivers' distress is likely to have positive effects on the overall health and capacity to care. Frameworks for providing palliative care to people with advanced dementia and support the caregivers would enhance the quality of care provided and may reduce the distress on the caregiver.

Caring for a family member or friend with dementia at the end of life: A scoping review and implications for palliative care practice

BACKGROUND

Although people with dementia receive substantial care from informal sources, there is limited research available that investigates how these carers experience end-of-life care.

AIM

This review aimed to identify what is currently known about carers' experiences of providing end-of-life care to a family member or friend with dementia and draw implications for palliative care policy and service provision.

DESIGN

A scoping literature review was conducted, first using a targeted key word search, followed by assessments of eligibility based on title and then abstract content.

DATA SOURCES

Records were sourced through PsycINFO, PubMed and CINAHL databases. Peer-reviewed papers published between 2000 and 2016, reporting on data collected directly from carers, were included for review.

RESULTS

Carers' experience centred on relationships (with care recipients, family and friends and health care professionals) and the specific context of caring for someone with dementia. These broad categories of carers' experiences had clear influences on them personally, particularly in relation to their sense of self and their wellbeing.

CONCLUSION

Palliative care services would benefit from ensuring holistic approaches to supporting people with dementia, their carers and wider family networks. Tailoring services to the specific context of dementia would enable effective, personalised support throughout extended periods leading up to care recipient death as well as through the challenges faced beyond bereavement.

Palliative Care for Dementia

With the growing care needs for the older population at the end of their lives, there has been a substantial increase in attention to the management of the patient with dementia in hospice and palliative care services. This article reviews issues in access to care and the optimal management of the patient with dementia, particularly in the context of neuropsychiatric complexities. Special issues such as delirium, cachexia, behavioral symptoms, and pain management are addressed. Future challenges in research such as the development of better prognostic models are noted as well as the importance of attention to access to care.

Race/Ethnicity as a Predictor for Location of Death in Patients With Acute Neurovascular Events

BACKGROUND

Site of death is an important quality indicator for patients with terminal illness. Racial and ethnic disparities exist in the quality of end-of-life care. This study explores the site of death of patients admitted for and dying of complications of acute neurovascular events in a hospital network in an urban, low-income, predominantly minority community.

METHODS

This is a retrospective cohort study of patients admitted to 1 of 3 general hospitals that are part of an academic medical center in Bronx, New York, with the diagnosis of acute ischemic stroke, intracerebral hemorrhage, or subarachnoid hemorrhage who died during the index admission or were discharged with hospice services. The main outcome was location of death (palliative care inpatient unit [IPU] at the medical center or hospice services at discharge vs death on any other IPU).

RESULTS

A total of 655 patients admitted with acute neurovascular events from January 1, 2009, to March 1, 2015, died or were discharged with hospice services and were included in the analysis. Of those patients, 238 (36.3%) were black, 233 (35.5%) were Hispanic, and 184 (28.1%) were white. A total of 178 (24.4%) died on the palliative care unit or were discharged with hospice services, including 55 black patients (23.1%), 52 (28.3%) white patients, and 53 (22.7%) Hispanic patients. These differences were not statistically significant, even when controlling for confounders.

CONCLUSION

This study did not show a difference in site of death in our institution by race or ethnicity, which is considered an important quality end-of-life care metric.

A systematic review of the psychobiological burden of informal caregiving for patients with dementia: Focus on cognitive and biological markers of chronic stress

As the physiological impact of chronic stress is difficult to study in humans, naturalistic stressors are invaluable sources of information in this area. This review systematically evaluates the research literature examining biomarkers of chronic stress, including neurocognition, in informal dementia caregivers. We identified 151 papers for inclusion in the final review, including papers examining differences between caregivers and controls as well as interventions aimed at counteracting the biological burden of chronic caregiving stress. Results indicate that cortisol was increased in caregivers in a majority of studies examining this biomarker. There was mixed evidence for differences in epinephrine, norepinephrine and other cardiovascular markers. There was a high level of heterogeneity in immune system measures. Caregivers performed more poorly on attention and executive functioning tests. There was mixed evidence for memory performance. Interventions to reduce stress improved cognition but had mixed effects on cortisol. Risk of bias was generally low to moderate. Given the rising need for family caregivers worldwide, the implications of these findings can no longer be neglected.

The extended palliative phase of dementia – An integrative literature review

This article presents an integrative literature review of the experience of dementia care associated with the extended palliative phase of dementia. The aim was to highlight how dementia is defined in the literature and describe what is known about the symptomatology and management of advanced dementia regarding the needs and preferences of the person with dementia and their family carer/s. There was no consistent definition of advanced dementia. The extended palliative phase was generally synonymous with end-of-life care. Advanced care planning is purported to enable professionals to work together with people with dementia and their families. A lack of understanding of palliative care among frontline practitioners was related to a dearth of educational opportunities in advanced dementia care. There are few robust concepts and theories that embrace living the best life possible during the later stages of dementia. These findings informed our subsequent work around the concept, ‘Dementia Palliare’.

Dementia Caregiver Grief and Bereavement: An Integrative Review

Alzheimer's disease and related dementias make up the fifth leading cause of death for individuals of 65 years of age and older in the United States. Seventy percent of these individuals will die in long-term care settings. The aim of this integrative review was to examine and synthesize the evidence on grief and bereavement in Alzheimer's disease and related dementias caregivers. This review identified five critical gaps in the existing evidence: (a) a lack of ethnic and gender diversity among caregivers studied, (b) limited use of valid instruments to study dementia caregiver grief and bereavement,
