Does a novel community-based outpatient palliative care intervention for Parkinson's disease and related disorders improve care? Qualitative results from patients and care partners.

BACKGROUND: Palliative care has the potential to address significant unmet needs in people with Parkinson's disease and related disorders, but models that rely on in-person specialty palliative care teams have limited scalability. AIM: To describe patient and care partner experiences with a novel, community-based palliative care intervention for Parkinson's disease. DESIGN: Qualitative study embedded in a randomized clinical trial to document participant experiences with a novel palliative care intervention (community neurologist training and remote team-based specialist palliative care). Transcripts were coded and thematically analyzed through a combination of team-based inductive and deductive coding. SETTING/PARTICIPANTS: Twenty-eight patients and 33 care partners purposively sampled from participants in a randomized clinical trial of a palliative care intervention for Parkinson's disease and related disorders conducted at nine sites. RESULTS: Benefits of the intervention included management of a wider range of non-motor symptoms, facilitation of conversations about the future, greater engagement with the health care team, and increased referrals to resources. Participants identified areas of improvement, including uptake of palliative care training by community neurologists, additional prognostic counseling, and clarity and timeliness of communication with the multidisciplinary team. CONCLUSIONS: Clinicians caring for people with Parkinson's disease and related disorders should screen for non-motor symptoms, provide regular prognostic counseling, and refer to specialty palliative care services earlier in the course of illness. Future interventions should be designed to promote uptake of palliative care training by community neurologists and further optimize referral to and coordination with in-person or remote specialty palliative teams.

In sickness and in health: Loneliness, depression, and the role of marital quality among spouses of persons with dementia.

BACKGROUND: Older adults married to persons living with dementia (PLwD) may be at risk for loneliness and depression. We assessed the prevalence of loneliness and depressive symptoms among spouses of PLwD or cognitive impairment not dementia (CIND), and the role of marital quality in mediating these outcomes. METHODS: We used a US population-based sample of 4071 couples enrolled in the Health and Retirement Study (2014 and 2016). We included older adults married to PLwD (N = 227), married to persons with CIND (N = 885), or married to persons with no cognitive impairment (NCI) (N = 2959). We determined the prevalence of loneliness (UCLA 3-item scale), depressive symptoms (CESD-8 scale), and both, using multivariable logistic regression adjusting for sociodemographic and health-related characteristics. We then tested for interaction terms between marital quality (4-item scale) and degree of spousal cognitive impairment for each outcome of loneliness and depressive symptoms. RESULTS: The sample was 55% women and on average 67-years-old (range: 50-97). After adjustment, spouses of persons with cognitive impairment were more likely to be lonely (NCI: 20%, CIND: 23%, PLwD: 29%; p = 0.04), depressed (NCI: 8%, CIND: 15%, PLwD: 14%; p < 0.01), and both (NCI: 4%, CIND: 9%, PLwD: 7%; p < 0.01). The association between cognition and loneliness, but not depression, differed by marital quality (interaction p-value = 0.03). Among couples with high marital quality, spousal cognitive impairment was associated with higher likelihood of loneliness (p < 0.05). In contrast, no association existed between spousal cognition and loneliness among couples with lower marital quality (p = 0.37). CONCLUSIONS: One in six spouses of persons with CIND or more advanced disease (PLwD) experienced depressive symptoms, and loneliness among spouses of PLwD was experienced at a twofold rate. By identifying and managing both, and facilitating interventions that promote high-quality social connection, clinical teams might improve the lives of older couples facing dementia.

Barriers of Acceptance to Hospice Care: a Randomized Vignette-Based Experiment.

BACKGROUND: The per diem financial structure of hospice care may lead agencies to consider patient-level factors when weighing admissions. OBJECTIVE: To investigate if treatment cost, disease complexity, and diagnosis are associated with hospice willingness to accept patients. DESIGN: In this 2019 online survey study, individuals involved in hospice admissions decisions were randomized to view one of six hypothetical patient vignettes: "high-cost, high-complexity," "low-cost, high-complexity," and "low-cost, low-complexity" within two diseases: heart failure and cystic fibrosis. Vignettes included demographics, prognoses, goals, and medications with costs. Respondents indicated their perceived likelihood of acceptance to their hospice; if likelihood was <100%, respondents were asked the barriers to acceptance. We used bivariate tests to examine associations between demographic, clinical, and organizational factors and likelihood of acceptance. PARTICIPANTS: Individuals involved in hospice admissions decisions MAIN MEASURES: Likelihood of acceptance to hospice care KEY RESULTS: N=495 (76% female, 53% age 45-64). Likelihoods of acceptance in cystic fibrosis were 79.8% (high-cost, high-complexity), 92.4% (low-cost, high-complexity), and 91.5% (low-cost, low-complexity), and in heart failure were 65.9% (high-cost, high-complexity), 87.3% (low-cost, high-complexity), and 96.6% (low-cost, low-complexity). For both heart failure and cystic fibrosis, respondents were less likely to accept the high-cost, high-complexity patient than the low-cost, high-complexity patient (65.9% vs. 87.3%, 79.8% vs. 92.4%, both p<0.001). For heart failure, respondents were less likely to accept the low-cost, high-complexity patient than the low-cost, low-complexity patient (87.3% vs. 96.6%, p=0.004). Treatment cost was the most common barrier for 5 of 6 vignettes. CONCLUSIONS: This study suggests that patients receiving expensive and/or complex treatments for palliation may have difficulty accessing hospice.

"I Didn't Sign Up for This": Perspectives from Persons Living with Dementia and Care Partners on Challenges, Supports, and Opportunities to Add Geriatric Neuropalliative Care to Dementia Specialty Care.

BACKGROUND: In the United States, dementia specialty centers affiliated with centers of excellence for research hold promise as locations to develop innovative, holistic care in care systems otherwise siloed by discipline or payer. OBJECTIVE: We conducted foundational research to inform development of patient-and family-centered palliative care interventions for dementia specialty centers. METHODS: We interviewed persons living with dementia (PLWD), current, and former care partners (CP) recruited from a specialty dementia clinic and purposively selected for variation across disease syndrome and stage. A framework method of thematic analysis included coding, analytic matrices, and pattern mapping. RESULTS: 40 participants included 9 PLWD, 16 current CPs, and 15 former CPs of decedents; 48% impacted by Alzheimer's disease dementia. While help from family, support groups and adult day centers, paid caregiving, and sensitive clinical care were invaluable to PLWD, CPs, or both, these supports were insufficient to navigate the extensive challenges. Disease-oriented sources of distress included symptoms, functional impairment and falls, uncertainty and loss, and inaccessible care. Social and relational challenges included constrained personal and professional opportunities. The obligation and toll of giving or receiving caregiving were challenging. Clinical care challenges for PLWD and/or CPs included care fragmentation, insufficient guidance to inform planning and need for expert interdisciplinary clinical care at home. CONCLUSION: Findings highlight the breadth and gravity of gaps, which surpass the disciplinary focus of either behavioral neurology or palliative care alone. Results can inform the development of novel interventions to add principles of geriatrics and neuropalliative care to dementia care.

Hospice Improves Care Quality For Older Adults With Dementia In Their Last Month Of Life.

The Medicare hospice benefit was originally designed around a cancer disease paradigm but increasingly serves people living with dementia. At this time, almost half of all older adults receiving hospice care have dementia. Yet there is minimal evidence as to whether hospice benefits people living with dementia outside of nursing facilities. We asked whether and how the perceived quality of last-month-of-life care differed between people with and without dementia and whether hospice use among people living with dementia was associated with perceived quality of care compared with the quality of care for those who did not use hospice. We used nationally representative data from the National Health and Aging Trends Study and Medicare claims from the period 2011-17 to examine the impact of hospice enrollment on proxy perceptions of last-month-of-life care quality. Proxies of people living with dementia enrolled in hospice compared with proxies of those not enrolled more often reported care to be excellent (predicted probability: 52 percent versus 41 percent), more often reported having anxiety or sadness managed (67 percent versus 46 percent), and less often reported changes in care settings in the last three days of life (10 percent versus 25 percent). There were no differences in the impact of hospice on proxy ratings of care for people with and without dementia. Policy makers should consider these benefits when weighing changes to hospice policy and regulations that may affect people living with dementia.

Life expectancy for community-dwelling persons with dementia and severe disability.

BACKGROUND: Understanding life expectancy can help persons with dementia, their care partners, and policymakers plan for what lies ahead. We sought to determine life expectancy and predictors of mortality for community-dwelling persons with dementia and severe disability. METHODS: Using the National Health and Aging Trends Study (NHATS) linked to Medicare claims, we identified community-dwelling respondents age 65+ who entered NHATS in 2011 with dementia and severe disability (defined as three impairments in activities of daily living), or who subsequently met criteria for dementia and then severe disability. We estimated time to death based on the timing of meeting severe disability criteria. We conducted parametric survival analyses using a Gompertz distribution to calculate risk of death and predicted median time to death. Predictors included demographic, functional, clinical characteristics, and behavioral symptoms (assessed among NHATS respondents with proxy interviews). RESULTS: Among 842 community-dwelling persons with dementia and severe disability, 80.5% died during the study period. After adjusting for age and gender, overall predicted median time to death was 1.7 years (25th percentile 0.6, 75th percentile 3.8 years). Six notable characteristics were associated with shorter life expectancy: 1) older age (90+), with a predicted median time to death of 1.0 year (0.4, 2.1); 2) being bedbound, 1.1 years (0.4, 2.3); 3) being homebound, 1.2 years (0.5, 2.6); 4) having comorbid cancer, 1.2 years (0.5, 2.6); 5) unintended weight loss, 1.4 years (0.5, 3.1); and 6) comorbid depression, 1.5 years (0.6, 3.3). CONCLUSIONS: Community-dwelling persons with dementia and severe disability lived a median of 1.7 years. Clinicians can use the study findings to provide anticipatory guidance to patients and care partners, and policymakers to inform design of longitudinal supportive services.

Community-Based Palliative Care Consultations: Comparing Dementia to Nondementia Serious Illnesses.

Background: Little is known about the provision of palliative care to people with dementia (PWD). Objective: To examine demographic and clinical characteristics of PWD versus nondementia serious illnesses receiving community-based palliative care. Design: Retrospective study of people 65+ receiving an initial consultation from a community-based palliative care practice between September 2014 and February 2018 using registry data entered by clinicians into the Quality Data Collection Tool for Palliative Care. Setting: Large not-for-profit organization that provides community-based hospice and palliative care services. Measurements: Demographics, consult characteristics, advance care planning, and caregiver support. Results: Of 3883 older adults receiving a first palliative care consultation from this organization, 22% (855) had a dementia diagnosis. Compared to those with nondementia serious illnesses, PWD were older with more impaired function; 36% had a prognosis of less than six months. More PWD than those without dementia had a proxy decision maker and documented advance directive. A quarter of PWD were full code before consultation; nearly half changed to some limitation afterward. Symptom characteristics were missing for 67% of PWD due to collection through self-report. Caregivers of PWD were responsible for significantly more activities of daily living than caregivers of people with nondementia serious illnesses. Conclusions: This is the first comparison of a large cohort of people with and without dementia receiving a community-based palliative care consult in the United States. Alternative measures of symptom burden should be used in registries to capture data for PWD. Understanding the unique characteristics of PWD will guide future services for this growing population.

What's Happening at Home: A Claims-based Approach to Better Understand Home Clinical Care Received by Older Adults.

BACKGROUND: Home clinical care (HCC) includes home-based medical care (HBMC-medical visits in the home) and skilled home health care (skilled nursing or therapy visits). Over 7 million older adults would benefit from HCC; however, we know surprisingly little about homebound older adults and HCC. OBJECTIVE: To describe HCC received by older adults using claims data within the OptumLabs Data Warehouse. RESEARCH DESIGN: Using administrative claims data for commercial and Medicare Advantage enrollees, we describe morbidity profiles, health service use, and care coordination (operationalized as care plan oversight [CPO]) for people receiving HCC and the subgroup receiving HBMC. PARTICIPANTS: Three million adults (3,027,247) age ≥65 with 12 months of continuous enrollment 2013-2014. MEASURES: CPT or HCPCS codes delineated HCC, HBMC, and CPO recipients and care site, frequency, and provider type. Other measures included demographic characteristics, clinical characteristics, and health care utilization. RESULTS: Overall, 5% of the study population (n=161,801) received 2+ months of HCC visits; of these, 46% also received 2+ HBMC visits (n=73,638) while 54% received only skilled home health (n=88,163 HCC but no HBMC). HBMC-recipients had high comorbidity burden (Charlson score 4.3), dementia (35%), and ambulance trips (58%), but few nursing facility admissions (4.9%). Evidence of care coordination (CPO claims) occurred in 30% of the HCC population, 46% of HBMC, and 17% of the skilled home health care only. CONCLUSIONS: Approximately 1 of 20 older adults in this study received HCC; 30% or less have a claim for care coordination by their primary care provider.

Secondary Analysis of Existing Datasets for Dementia and Palliative Care Research: High-Value Applications and Key Considerations.

OBJECTIVE: To provide a guide to researchers selecting a dataset pertinent to the study of palliative care for people with dementia and to aid readers who seek to critically evaluate a secondary analysis study in this domain. BACKGROUND: The impact of dementia at end-of-life is large and growing. Secondary dataset analysis can play a critical role in advancing research on palliative care for people with dementia. METHODS: We conducted a broad search of a variety of resources to: 1. identity datasets that include information germane to dementia and palliative care research; 2. review relevant applications of secondary dataset analysis in the published literature; and 3. explore potential validity and reliability concerns. RESULTS: We synthesize findings regarding: 1. Methodological approaches for determining the presence of dementia; 2. Inclusion and measurement of key palliative care items as they relate to people with dementia; and 3. Sampling and study design issues, including the role and implications of proxy-respondents. We describe and compare a selection of high-value existing datasets relevant to palliative care and dementia research. DISCUSSION: While secondary analysis of existing datasets requires consideration of key limitations, it can be a powerful tool for efficiently enhancing knowledge of palliative care needs among people with dementia.

Addressing Palliative Care Clinician Burnout in Organizations: A Workforce Necessity, an Ethical Imperative.

Clinician burnout reduces the capacity for providers and health systems to deliver timely, high quality, patient-centered care and increases the risk that clinicians will leave practice. This is especially problematic in hospice and palliative care: patients are often frail, elderly, vulnerable, and complex; access to care is often outstripped by need; and demand for clinical experts will increase as palliative care further integrates into usual care. Efforts to mitigate and prevent burnout currently focus on individual clinicians. However, analysis of the problem of burnout should be expanded to include both individual- and systems-level factors as well as solutions; comprehensive interventions must address both. As a society, we hold organizations responsible for acting ethically, especially when it relates to deployment and protection of valuable and constrained resources. We should similarly hold organizations responsible for being ethical stewards of the resource of highly trained and talented clinicians through comprehensive programs to address burnout.

Improving the Quality of Palliative Care Through National and Regional Collaboration Efforts.

BACKGROUND: The measurement and reporting of the quality of care in the field of palliation has become a required task for many health care leaders and specialists in palliative care. Such efforts are aided when organizations collaborate together to share lessons learned. METHODS: The authors reviewed examples of quality-improvement collaborations in palliative care to understand the similarities, differences, and future directions of quality measurement and improvement strategies in the discipline. RESULTS: Three examples were identified that showed areas of robust and growing quality-improvement collaboration in the field of palliative care: the Global Palliative Care Quality Alliance, Palliative Care Quality Network, and Project Educate, Nurture, Advise, Before Life Ends. These efforts exemplify how shared-improvement activities can inform improved practice for organizations participating in collaboration. CONCLUSIONS: National and regional collaboratives can be used to enhance the quality of palliative care and are important efforts to standardize and improve the delivery of palliative care for persons with serious illness, along with their friends, family, and caregivers.

The H1 histamine receptor regulates allergic lung responses.

Histamine, signaling via the type 1 receptor (H1R), has been shown to suppress Th2 cytokine production by in vitro cultured T cells. We examined the role of H1R in allergic inflammation in vivo using a murine asthma model. Allergen-stimulated splenic T cells from sensitized H1R-/- mice exhibited enhanced Th2 cytokine production. Despite this Th2 bias, allergen-challenged H1R-/- mice exhibited diminished lung Th2 cytokine mRNA levels, airway inflammation, goblet cell metaplasia, and airway hyperresponsiveness (AHR). Restoration of pulmonary Th2 cytokines in H1R-/- mice by intranasal IL-4 or IL-13 restored inflammatory lung responses and AHR. Further investigation revealed that histamine acts as a T cell chemotactic factor and defective T cell trafficking was responsible for the absence of lung inflammation. Cultured T cells migrated in response to histamine in vitro, but this was ablated by blockade of H1R but not H2R. In vivo, allergen-specific WT but not H1R-/- CD4+ T cells were recruited to the lungs of naive recipients following inhaled allergen challenge. H1R-/- T cells failed to confer airway inflammation or AHR observed after transfer of WT T cells. Our data establish a role for histamine and H1R in promoting the migration of Th2 cells into sites of allergen exposure.
