Prediction of 6-month survival of nursing home residents with advanced dementia using ADEPT vs hospice eligibility guidelines

Prognostic understanding among caregivers of persons with dementia: A scoping review

INTRODUCTION

Despite the influence of caregivers' prognostic understanding (PU) on the end-of-life care for persons with dementia (PwDs), the literature on PU of caregivers of PwDs is sparse. We conducted a scoping review to understand the variation in existing definitions and measurement of caregivers' PU for PwDs. We also aimed to synthesize the prevalence of caregivers' correct PU and the factors (caregiver, PwD and healthcare related) associated with it.

METHODS

We systematically searched four databases-MEDLINE/PubMed, EMBASE, SCOPUS, and CINAHL. We included studies where study participants were informal caregivers, their PU was assessed, and measurement tool was implicitly described. We excluded studies where study participants were paid caregivers.

RESULTS

Out of the 2160 studies screened, we included 15 published between 2009 and 2023. The included studies measured caregivers' PU as limited estimated life expectancy, understanding that dementia is incurable and life-limiting. Estimated life expectancy was the most common measure of PU among caregivers to PwDs. Across studies, around 90% of caregivers acknowledged dementia as incurable, while only about 40% acknowledged it as life-limiting. Caregivers of PwDs who were sicker (acute medical problems or functional dependence) and those who had discussed goals of care with healthcare providers were more likely to have more accurate PU for PwDs. Caregivers' with better PU were more likely to state a preference for comfort-focused care, and their PwDs were likely to receive fewer burdensome interventions and experience greater comfort during the dying process.

CONCLUSION

Our findings highlight the need for a comprehensive measure to assess the multifaceted nature of caregivers' PU, delve deeper into factors influencing caregivers' PU, and explore its impact on caregivers themselves.

Factors associated with the place of death of persons with advanced dementia: A systematic review of international literature with meta-analysis

BACKGROUND

Many individuals with advanced dementia die in hospital, despite preferring home death. Existing evidence of factors affecting their place of death is inconsistent. To inform policies/practices for meeting needs/preferences, systematically establishing the evidence is pertinent, particularly given the exponential rise in advanced dementia prevalence.

AIM

To identify factors influencing where people with advanced dementia die.

DESIGN AND DATA SOURCES

This systematic review with meta-analysis was registered on PROSPERO (CRD42022366722). Medline, CINAHL, PsycINFO, SocINDEX and a grey literature database, Overton, were searched on 21/12/2022, supplemented by hand-searching/citation tracking. Papers reporting quantitative data on factors associated with place of death in advanced dementia were included and appraised using QualSyst. Data were analysed using random effects with the certainty of evidence determined using the GRADE criteria.

RESULTS

Thirty-three papers involving >5 million individuals (mean age = 89.2 years) were included. Long-term care setting deaths were relatively common but hospice deaths were rarer. Marriage's association with home death underscores social networks' importance, while younger age's and male gender's associations with hospital death demonstrate patients' and families' interdependency. Pneumonia/COPD's opposing effects on hospital deaths with cancer/functional impairment highlight the challenges of advanced dementia care. Unlike hospital/nursing home bed availability's lack of effect, capitated funding (fixed-amount-per-patient-per-period) decreased hospital death likelihood.

CONCLUSION

This comprehensive review of place of death determinants highlight the profound challenges of advanced dementia end-of-life care. Given that bed capacity did not affect place of death, a capitation-based, integrated palliative care model would appear more likely to meet patients' needs in a resource-constrained environment.

Top Ten Tips Palliative Care Clinicians Should Know About Hospice Live Discharge

Hospice care is designed to support the medical and psychosocial needs of individuals with serious illness and their caregivers through the dying process. Some individuals, though, leave hospice prior to death, generally referred to as disenrollment or a "live discharge." Live discharge from hospice is a common and often distressing issue for hospice patients, their caregivers, and also for hospice professionals and agencies. This paper discusses common issues surrounding live discharge that clinicians and other healthcare professionals should consider when dealing with live discharge in their own clinical practices. Where applicable, we provide practical steps for hospice and palliative care clinicians to better support patients and families through this critical care transition. Further, we offer strategic directions interprofessional clinicians can take to affect systemic change to improve live discharge experiences.

Which medicare advantage enrollees are at highest one-year mortality risk?

BACKGROUND

While a number of tools exist to predict mortality among older adults, less research has described the characteristics of Medicare Advantage (MA) enrollees at higher risk for 1 year mortality.

OBJECTIVES

To describe the characteristics of MA enrollees at higher mortality risk using patient survey data.

RESEARCH DESIGN

Retrospective cohort.

SUBJECTS

MA enrollees completing the 2019 MA Consumer Assessment of Healthcare Providers and Systems (CAHPS) Survey.

MEASURES

Linked demographic, health, and mortality data from a sample of MA enrollees were used to predict 1-year mortality risk and describe enrollee characteristics across levels of predicted mortality risk.

RESULTS

The mortality model had a 0.80 c-statistic. Mortality risks were skewed: 6 % of enrollees had a ≥ 10 % 1-year mortality risk, while 45 % of enrollees had 1 % to < 5 % 1-year mortality risk. Among the high-risk (≥10 %) group, 47 % were age 85+ versus 12 % among those with mortality risk <5 %. 79 % were in fair or poor self-rated health versus 29 % among those with mortality risk of <5 %. 71 % reported needing urgent care in the prior 6 months versus 40 % among those with a mortality risk of 1 to<5 %.

CONCLUSIONS

Relatively few older adults enrolled in MA are at high 1-year mortality risk. Nonetheless, MA enrollees over age 85, in fair or poor health, or with recent urgent care needs are far more likely to be in a high mortality risk group.

End-of-life experiences in individuals with dementia with Lewy bodies and their caregivers: A mixed-methods analysis

BACKGROUND

Dementia with Lewy bodies (DLB) is one of the most common degenerative dementias, but research on end-of-life experiences for people with DLB and their caregivers is limited.

METHOD

Dyads of individuals with moderate-advanced DLB and their primary informal caregivers were recruited from specialty clinics, advocacy organizations, and research registries and followed prospectively every 6 months. The current study examines results of caregiver study visits 3 months after the death of the person with DLB. These visits included the Last Month of Life survey, study-specific questions, and a semi-structured interview querying end-of-life experiences.

RESULTS

Individuals with DLB (n = 50) died 3.24 ± 1.81 years after diagnosis, typically of disease-related complications. Only 44% of caregivers reported a helpful conversation with clinicians regarding what to expect at the end of life in DLB. Symptoms commonly worsening prior to death included: cognition and motor function, ADL dependence, behavioral features, daytime sleepiness, communication, appetite, and weight loss. Almost 90% of participants received hospice care, but 20% used hospice for <1 week. Most caregivers reported overall positive experiences in the last month of life, but this was not universal. Having information about DLB and what to expect, access to support, and hospice care were healthcare factors associated with positive and negative end of life experiences. Hospice experiences were driven by communication, care coordination, quality care, and caregiver education.

CONCLUSION

Most caregivers of individuals who died with DLB reported positive end-of-life experiences. However, the study identified multiple opportunities for improvement relating to clinician counseling of patients/families, support/hospice referrals, and monitoring individuals with DLB to identify approaching end of life. Future research should quantitatively identify changes that herald end of life in DLB and develop tools that can assist clinicians in evaluating disease stage to better inform counseling and timely hospice referrals.

Prognostic models and factors identifying end-of-life in non-cancer chronic diseases: a systematic review

BACKGROUND

Precise prognostic information, if available, is very helpful for guiding treatment decisions and resource allocation in patients with non-cancer non-communicable chronic diseases (NCDs). This study aimed to systematically review the existing evidence, examining prognostic models and factors for identifying end-of-life non-cancer NCD patients.

METHODS

Electronic databases, including Medline, Embase, CINAHL, Cochrane Library, PsychINFO and other sources, were searched from the inception of these databases up until June 2023. Studies published in English with findings mentioning prognostic models or factors related to identifying end-of-life in non-cancer NCD patients were included. The quality of studies was assessed using the Quality in Prognosis Studies tool.

RESULTS

The analysis included data from 41 studies, with 16 focusing on chronic obstructive pulmonary diseases (COPD), 10 on dementia, 6 on heart failure and 9 on mixed NCDs. Traditional statistical modelling was predominantly used for the identified prognostic models. Common predictors in COPD models included dyspnoea, forced expiratory volume in 1 s, functional status, exacerbation history and body mass index. Models for dementia and heart failure frequently included comorbidity, age, gender, blood tests and nutritional status. Similarly, mixed NCD models commonly included functional status, age, dyspnoea, the presence of skin pressure ulcers, oral intake and level of consciousness. The identified prognostic models exhibited varying predictive accuracy, with the majority demonstrating weak to moderate discriminatory performance (area under the curve: 0.5-0.8). Additionally, most of these models lacked independent external validation, and only a few underwent internal validation.

CONCLUSION

Our review summarised the most relevant predictors for identifying end-of-life in non-cancer NCDs. However, the predictive accuracy of identified models was generally inconsistent and low, and lacked external validation. Although efforts to improve these prognostic models should continue, clinicians should recognise the possibility that disease heterogeneity may limit the utility of these models for individual prognostication; they may be more useful for population level health planning.

Usefulness of Palliative Prognostic Index, Objective Prognostic Score, and Neutrophil-Lymphocyte Ratio/Albumin Ratio As Prognostic Indicators for Patients Without Cancer Receiving Home-Visit Palliative Care: A Pilot Study at a Community General Hospital

Background

Although the palliative prognostic index (PPI), objective prognostic score (OPS), and neutrophil-lymphocyte ratio/albumin ratio (NLR/Alb) are well-known prognostic indicators for cancer patients, they do not provide clarity when it comes to predicting prognosis in patients without cancer who receive home-visit palliative care.

Objective

The aim of this study was to determine whether PPI, OPS, and NLR/Alb can predict prognosis for patients without cancer who received home-visit palliative care.

Design

This is a retrospective study.

Setting/Subjects

We recruited 58 patients without cancer who received home-visit palliative care from Tokushima Prefectural Kaifu Hospital, Japan, and died at home or at the hospital within seven days of admission between January 2009 and March 2023.

Measurements

The PPI, OPS, and NLR/Alb of the study patients were evaluated at regular intervals, and statistical analysis was performed on the relationship between these indices and the time to death.

Results

Simple regression analysis showed that PPI, OPS, and NLR/Alb were negatively correlated with the period until death (p < 0.001). The survival curves of the groups classified according to PPI, OPS, and NLR/Alb were significantly stratified. The predictive capacities of PPI, OPS, and NLR/Alb for death within 21 days were as follows: PPI (area under the curve [AUC]: 0.71; sensitivity: 59%; specificity: 68%), OPS (AUC: 0.73; sensitivity: 88%; specificity: 47%), and NLR/Alb (AUC: 0.72; sensitivity: 72%; specificity: 73%).

Conclusions

PPI, OPS, and NLR/Alb were useful in predicting the survival period and short-term prognosis within 21 days for patients without cancer who received home-visit palliative care.

Study protocol for the development and validation of a clinical prediction tool to estimate the risk of 1-year mortality among hospitalized patients with dementia

BACKGROUND

Patients with dementia and their caregivers could benefit from advance care planning though may not be having these discussions in a timely manner or at all. A prognostic tool could serve as a prompt to healthcare providers to initiate advance care planning among patients and their caregivers, which could increase the receipt of care that is concordant with their goals. Existing prognostic tools have limitations. We seek to develop and validate a clinical prediction tool to estimate the risk of 1-year mortality among hospitalized patients with dementia.

METHODS

The derivation cohort will include approximately 235,000 patients with dementia, who were admitted to hospital in Ontario from April 1st, 2009, to December 31st, 2017. Predictor variables will be fully prespecified based on a literature review of etiological studies and existing prognostic tools, and on subject-matter expertise; they will be categorized as follows: sociodemographic factors, comorbidities, previous interventions, functional status, nutritional status, admission information, previous health care utilization. Data-driven selection of predictors will be avoided. Continuous predictors will be modelled as restricted cubic splines. The outcome variable will be mortality within 1 year of admission, which will be modelled as a binary variable, such that a logistic regression model will be estimated. Predictor and outcome variables will be derived from linked population-level healthcare administrative databases. The validation cohort will comprise about 63,000 dementia patients, who were admitted to hospital in Ontario from January 1st, 2018, to March 31st, 2019. Model performance, measured by predictive accuracy, discrimination, and calibration, will be assessed using internal (temporal) validation. Calibration will be evaluated in the total validation cohort and in subgroups of importance to clinicians and policymakers. The final model will be based on the full cohort.

DISCUSSION

We seek to develop and validate a clinical prediction tool to estimate the risk of 1-year mortality among hospitalized patients with dementia. The model would be integrated into the electronic medical records of hospitals to automatically output 1-year mortality risk upon hospitalization. The tool could serve as a trigger for advance care planning and inform access to specialist palliative care services with prognosis-based eligibility criteria. Before implementation, the tool will require external validation and study of its potential impact on clinical decision-making and patient outcomes.

Live Discharge of Hospice Patients with Alzheimer's Disease and Related Dementias: A Systematic Review

Background: Hospice is intended to promote the comfort and quality of life of dying patients and their families. When patients are discharged from hospice prior to death (ie, experience a "live discharge"), care continuity is disrupted. This systematic review summarizes the growing body of evidence on live discharge among hospice patients with Alzheimer's Disease and related dementias (ADRD), a clinical subpopulation that disproportionately experiences this often burdensome care transition. Methods: Researchers conducted a systematic review in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Reviewers searched AgeLine, APA PsycINFO (Ovid), CINAHL Plus with Full Text, ProQuest Dissertations & Theses Global, PubMed, Scopus, and Web of Science (Core Collection). Reviewers extracted data and synthesized findings from 9 records, which reported findings from 10 individual studies. Results: The reviewed studies, which were generally of high quality, consistently identified diagnosis of ADRD as a risk factor for live discharge from hospice. The relationship between race and live hospice discharge was less clear and likely dependent upon the type of discharge under investigation and other (eg, systemic-level) factors. Research on patient and family experiences underscored the extent to which live hospice discharge can be distressing, confusing, and associated with numerous losses. Conclusion: Research specific to live discharge among ADRD patients and their families is limited. Synthesis across included studies points to the importance for future research to differentiate between types of live discharge-revocation vsversus decertification-as these are vastly different experiences in choice and circumstances.

Prediction of survival of persons with advanced dementia using the advanced dementia prognostic tool: A 2-year prospective study

BACKGROUND

In this prospective study, we evaluated the usefulness of the advanced dementia prognostic tool (ADEPT) for estimating the 2-year survival of persons with advanced dementia (AD) in China.

METHODS

The study predicted the 2-year mortality of 115 persons with AD using the ADEPT score.

RESULTS

In total, 115 persons with AD were included in the study. Of these persons, 48 died. The mean ADEPT score was 13.0. The AUROC for the prediction of the 2-year mortality rate using the ADEPT score was 0.62. The optimal threshold of the ADEPT score was 11.2, which had an AUROC of 0.63, specificity of 41.8, and sensitivity of 83.3.

CONCLUSIONS

The ADEPT score based on a threshold of 11.2 may serve as a prognostic tool to determine the 2-year survival rate of persons with AD in Chongqing, China. However, further studies are needed to explore the nature of this relationship.

Transitions of Care: Strategies for Medication Optimization and Deprescribing in Older Adults

Older adults have an increased risk of adverse drug events related to polypharmacy and potentially inappropriate medication (PIM) use. These patients are even more vulnerable as they transition through different health care settings. In 2023, the American Geriatrics Society published an updated version of the Beers Criteria®, providing updated guidance on identifying and managing PIMs. Nurses and nurse practitioners play important roles in medication management across the continuum of care. The current article aims to illustrate key concepts regarding medication safety and deprescribing for older adult patients during transitions of care.

Developing a predictive model for mortality in patients with cognitive impairment

OBJECTIVES

We developed a predictive model for all-cause mortality and examined the risk factors for cause-specific mortality among people with cognitive impairment in a Japanese memory clinic-based cohort (2010-2018).

METHODS

This retrospective cohort study included people aged ≥65 years with mild cognitive impairment or dementia. The survival status was assessed based on the response of participants or their close relatives via a postal survey. Potential predictors including demographic and lifestyle-related factors, functional status, and behavioral and psychological status were assessed at the first visit at the memory clinic. A backward stepwise Cox regression model was used to select predictors, and a predictive model was developed using a regression coefficient-based scoring approach. The discrimination and calibration were assessed via Harrell's C-statistic and a calibration plot, respectively.

RESULTS

A total of 2610 patients aged ≥65 years (men, 38.3%) were analyzed. Over a mean follow-up of 4.1 years, 544 patients (20.8%) died. Nine predictors were selected from the sociodemographic and clinical variables: age, sex, body mass index, gait performance, physical activity, and ability for instrumental activities of daily living, cognitive function, and self-reported comorbidities (pulmonary disease and diabetes). The model showed good discrimination and calibration for 1-5-year mortality (Harrell's C-statistic, 0.739-0.779). Some predictors were specifically associated with cause-specific mortality.

CONCLUSIONS

This predictive model has good discriminative ability for 1- to 5-year mortality and can be easily implemented for people with mild cognitive impairment and all stages of dementia referred to a memory clinic.

Palliative care to support the needs of adults with neurological disease

Neurological diseases cause physical, psychosocial, and spiritual or existential suffering from the time of their diagnosis. Palliative care focuses on improving quality of life for people with serious illness and their families by addressing this multidimensional suffering. Evidence from clinical trials supports the ability of palliative care to improve patient and caregiver outcomes by the use of outpatient or home-based palliative care interventions for people with motor neuron disease, multiple sclerosis, or Parkinson's disease; inpatient palliative care consultations for people with advanced dementia; telephone-based case management for people with dementia in the community; and nurse-led discussions with decision aids for people with advanced dementia in long-term care. Unfortunately, most people with neurological diseases do not get the support that they need for their palliative care under current standards of healthcare. Improving this situation requires the deployment of routine screening to identify individual palliative care needs, the integration of palliative care approaches into routine neurological care, and collaboration between neurologists and palliative care specialists. Research, education, and advocacy are also needed to raise standards of care.

Predicting mortality in patients diagnosed with advanced dementia presenting at an acute care hospital: the PROgnostic Model for Advanced DEmentia (PRO-MADE)

BACKGROUND

Challenges in prognosticating patients diagnosed with advanced dementia (AD) hinders timely referrals to palliative care. We aim to develop and validate a prognostic model to predict one-year all-cause mortality (ACM) in patients with AD presenting at an acute care hospital.

METHODS

This retrospective cohort study utilised administrative and clinical data from Tan Tock Seng Hospital (TTSH). Patients admitted to TTSH between 1st July 2016 and 31st October 2017 and identified to have AD were included. The primary outcome was ACM within one-year of AD diagnosis. Multivariable logistic regression was used. The PROgnostic Model for Advanced Dementia (PRO-MADE) was internally validated using a bootstrap resampling of 1000 replications and externally validated on a more recent cohort of AD patients. The model was evaluated for overall predictive accuracy (Nagelkerke's R² and Brier score), discriminative [area-under-the-curve (AUC)], and calibration [calibration slope and calibration-in-the-large (CITL)] properties.

RESULTS

A total of 1,077 patients with a mean age of 85 (SD: 7.7) years old were included, and 318 (29.5%) patients died within one-year of AD diagnosis. Predictors of one-year ACM were age > 85 years (OR:1.87; 95%CI:1.36 to 2.56), male gender (OR:1.62; 95%CI:1.18 to 2.22), presence of pneumonia (OR:1.75; 95%CI:1.25 to 2.45), pressure ulcers (OR:2.60; 95%CI:1.57 to 4.31), dysphagia (OR:1.53; 95%CI:1.11 to 2.11), Charlson Comorbidity Index ≥ 8 (OR:1.39; 95%CI:1.01 to 1.90), functional dependency in ≥ 4 activities of daily living (OR: 1.82; 95%CI:1.32 to 2.53), abnormal urea (OR:2.16; 95%CI:1.58 to 2.95) and abnormal albumin (OR:3.68; 95%CI:2.07 to 6.54) values. Internal validation results for optimism-adjusted Nagelkerke's R², Brier score, AUC, calibration slope and CITL were 0.25 (95%CI:0.25 to 0.26), 0.17 (95%CI:0.17 to 0.17), 0.76 (95%CI:0.76 to 0.76), 0.95 (95% CI:0.95 to 0.96) and 0 (95%CI:-0.0001 to 0.001) respectively. When externally validated, the model demonstrated an AUC of 0.70 (95%CI:0.69 to 0.71), calibration slope of 0.64 (95%CI:0.63 to 0.66) and CITL of -0.27 (95%CI:-0.28 to -0.26).

CONCLUSION

The PRO-MADE attained good discrimination and calibration properties. Used synergistically with a clinician's judgement, this model can identify AD patients who are at high-risk of one-year ACM to facilitate timely referrals to palliative care.

Functional and clinical needs of older hospice enrollees with coexisting dementia

BACKGROUND

The Medicare Hospice Benefit increasingly serves people dying with dementia. We sought to understand characteristics, hospice use patterns, and last-month-of-life care quality ratings among hospice enrollees with dementia coexisting with another terminal illness as compared to enrollees with a principal hospice diagnosis of dementia, and enrollees with no dementia.

METHODS

We conducted a pooled cross-sectional study among decedent Medicare beneficiaries age 70+ using longitudinal data from the National Health and Aging Trends Study (NHATS) (last interview before death; after-death proxy interview) linked to Medicare hospice claims (2011-2017). We used unadjusted and adjusted regression analyses to compare characteristics of hospice enrollees with coexisting dementia to two groups: (1) enrollees with a principal dementia diagnosis, and (2) enrollees with no dementia.

RESULTS

Among 1105 decedent hospice enrollees age 70+, 40% had coexisting dementia, 16% had a principal diagnosis of dementia, and 44% had no dementia. In adjusted analyses, enrollees with coexisting dementia had high rates of needing help with 3-6 activities of daily living, similar to enrollees with principal dementia (62% vs. 67%). Enrollees with coexisting dementia had high clinical needs, similar to those with no dementia, for example, 63% versus 61% had bothersome pain. Care quality was worse for enrollees with coexisting dementia versus principal dementia (e.g., 61% vs. 79% had anxiety/sadness managed) and similar to those with no dementia. Enrollees with coexisting dementia had similar hospice use patterns as those with principal diagnoses and higher rates of problematic use patterns compared to those with no dementia (e.g., 16% vs. 10% live disenrollment, p = 0.004).

CONCLUSIONS

People with coexisting dementia have functional needs comparable to enrollees with principal diagnoses of dementia, and clinical needs comparable to enrollees with no dementia. Changes to hospice care models and policy may be needed to ensure appropriate dementia care.

Development and validation of a nursing home mortality index to identify nursing home residents nearing the end of life in dental clinics

BACKGROUND

Nursing home (NH) residents seek care at dental offices, yet many of them are at the end of life. The uncertain life expectancy further complicates the care of NH residents. This study aimed to develop and validate a Nursing Home Mortality Index (NHMI) to identify NH residents in the last year of life.

METHODS

Logistic modeling was used to develop predictive models for death within 1 year after initial appointment by utilizing the new patient examination data and mortality data of 903 Minnesota NH residents. The final model was selected based on areas under the curve (AUC) and then validated using data from 586 Iowa NH residents. Based on the final model, the NHMI was developed with the estimated 1-year mortality for the low, medium and high risk group.

RESULTS

One-year mortalities were 21% and 26% in the development and validation cohorts, respectively. Predictors included age, gender, communication capacity, physical mobility, congestive heart failure, peripheral vascular disease, cancer, cerebrovascular disease, chronic renal disease and liver disease. AUCs for the development and validation models were 0.73 and 0.68, respectively. For the validation cohort, the sensitivity and specificity were 0.79 and 0.53, respectively. The estimated 1-year mortality risks for three risk groups were 0%-10%, 11%-19%, and ≥20%, respectively CONCLUSION: The high mortality rate of NH residents following a dental exam highlighted a need to incorporate patients' prognoses in treatment planning along with normative needs and patients' preferences. The NHMI provides a practical way to guide treatment decisions for end-of-life NH residents.

Identification and Prognostication of End-of-Life State Using a Japanese Guideline-Based Diagnostic Method: A Diagnostic Accuracy Study

Purpose

Prognostic uncertainty can be a barrier to providing palliative care. Accurate prognostic estimation for patients at the end of life is challenging. This study aimed to evaluate the accuracy of end-of-life diagnosis using our unique diagnostic method.

Patients and Methods

A retrospective longitudinal observational study was conducted through collaboration among three medical facilities in a rural super-aged community in Japan. In 2007, we established a unique end-of-life diagnostic process comprising (1) physicians' judgement, (2) disclosure to patients, and (3) discussion at an end-of-life case conference (EOL-CC), based on Japanese end-of-life-related guidelines. Research subjects were consecutive patients discussed in EOL-CC between January 1, 2010, and September 30, 2017. The primary outcome was mortality within 6 months after the initial EOL-CC decision. Sensitivity, specificity, and diagnostic odds ratio were calculated using EOL-CC diagnosis (end-of-life or non-end-of-life) as an index test and overall survival (<6 months or ≥6 months) as a reference standard.

Results

In total, 315 patients were eligible for survival analysis (median age 89, range 54-107). The study population was limited to patients with severe conditions such as advanced cancer, organ failures, advanced dementia with severe deterioration in functioning. EOL-diagnosis by our methods was associated with much lower survival rate at 6 months after EOL-CC than non-EOL-diagnosis (6.9% vs 43.5%; P < 0.001). Of the patients, 297 were eligible for diagnostic accuracy analysis (median age 89, range 54-107). The EOL-diagnosis showed high sensitivity (0.95; 95% confidence interval [CI] 0.92-0.97) but low specificity (0.35; 95% CI 0.20-0.53) against the outcomes. It also showed a high diagnostic odds ratio (10.32; 95% CI 4.08-26.13).

Conclusion

The diagnostic process using the Japanese end-of-life guidelines had tolerable accuracy in identification and prognostication of end of life.

Palliative care in Parkinson disease and related disorders

Although neuropalliative care is a relatively new field, there is increasing evidence for its use among the degenerative parkinsonian syndromes, including idiopathic Parkinson disease, progressive supranuclear palsy, multiple system atrophy, dementia with Lewy bodies, and corticobasal syndrome. This chapter outlines the current state of evidence for palliative care among individuals with the degenerative parkinsonian syndromes with discussion surrounding: (1) disease burden and needs across the conditions; (2) utility, timing, and methods for advance care planning; (3) novel care models for the provision of palliative care; and 4) end-of-life care issues. We also discuss currently unmet needs and unanswered questions in the field, proposing priorities for research and the assessment of implemented care models.

Palliative care for people with dementia

Dementia is the most common neurologic disease, affecting approximately 55 million people worldwide. Dementia is a terminal illness, although not always recognized as such. This chapter discusses the key issues in providing palliative care for people with living with dementia and their families. Common palliative care needs and symptoms are presented, including psychosocial, physical, emotional, and spiritual, and the need to actively anticipate and seek symptoms according to the dementia type and stage is emphasized. Families are hugely impacted by a dementia diagnosis, and throughout this chapter, they are considered in the unit of care, and also as a member of the care team. Multiple challenges particular to dementia palliative care are highlighted throughout, such as the lack of timely dementia diagnoses, difficulty with symptom prognostication, the person's inability to verbally express their symptoms and care preferences, and a low threshold for medication side effects. Finally, service models for dementia palliative care in community, residential, and acute hospital settings are discussed, along with the evidence for each. Overall, this chapter reinforces that the individual needs of the person living with dementia and their family must be considered to provide person-centered and comprehensive palliative care, enabling them to live well until death.

Executive summary of the position paper on the use of enteral nutrition in advanced dementia

Dementia is an increasingly prevalent disease in our environment, with significant health and social repercussions. Despite the available scientific evidence, there is still controversy regarding the use of enteral tube nutrition in people with advanced dementia. This document aims to reflect on the key aspects of advanced dementia, tube nutritional therapy and related ethical considerations, as well as to respond to several frequent questions that arise in our daily clinical practice.

Development and External Validation of a Mortality Prediction Model for Community-Dwelling Older Adults With Dementia

Importance

Estimating mortality risk in older adults with dementia is important for guiding decisions such as cancer screening, treatment of new and chronic medical conditions, and advance care planning.

Objective

To develop and externally validate a mortality prediction model in community-dwelling older adults with dementia.

Design, Setting, and Participants

This cohort study included community-dwelling participants (aged ≥65 years) in the Health and Retirement Study (HRS) from 1998 to 2016 (derivation cohort) and National Health and Aging Trends Study (NHATS) from 2011 to 2019 (validation cohort).

Exposures

Candidate predictors included demographics, behavioral/health factors, functional measures (eg, activities of daily living [ADL] and instrumental activities of daily living [IADL]), and chronic conditions.

Main Outcomes and Measures

The primary outcome was time to all-cause death. We used Cox proportional hazards regression with backward selection and multiple imputation for model development. Model performance was assessed by discrimination (integrated area under the receiver operating characteristic curve [iAUC]) and calibration (plots of predicted and observed mortality).

Results

Of 4267 participants with probable dementia in HRS, the mean (SD) age was 82.2 (7.6) years, 2930 (survey-weighted 69.4%) were female, and 785 (survey-weighted 12.1%) identified as Black. Median (IQR) follow-up time was 3.9 (2.0-6.8) years, and 3466 (81.2%) participants died by end of follow-up. The final model included age, sex, body mass index, smoking status, ADL dependency count, IADL difficulty count, difficulty walking several blocks, participation in vigorous physical activity, and chronic conditions (cancer, heart disease, diabetes, lung disease). The optimism-corrected iAUC after bootstrap internal validation was 0.76 (95% CI, 0.75-0.76) with time-specific AUC of 0.73 (95% CI, 0.70-0.75) at 1 year, 0.75 (95% CI, 0.73-0.77) at 5 years, and 0.84 (95% CI, 0.82-0.85) at 10 years. On external validation in NHATS (n = 2404), AUC was 0.73 (95% CI, 0.70-0.76) at 1 year and 0.74 (95% CI, 0.71-0.76) at 5 years. Calibration plots suggested good calibration across the range of predicted risk from 1 to 10 years.

Conclusions and Relevance

We developed and externally validated a mortality prediction model in community-dwelling older adults with dementia that showed good discrimination and calibration. The mortality risk estimates may help guide discussions regarding treatment decisions and advance care planning.

A national study of disenrollment from hospice among people with dementia

BACKGROUND

People with dementia (PWD) are at high risk for hospice disenrollment, yet little is known about patterns of disenrollment among the growing number of hospice enrollees with dementia.

DESIGN

Retrospective, observational cohort study of 100% Medicare beneficiaries with dementia aged 65 and older enrolled in the Medicare Hospice Benefit between July 2012 and December 2017. Outcome measures included hospice-initiated disenrollment for patients whose rate of decline ceased to meet the Medicare hospice eligibility guideline of "expected death within 6 months" (extended prognosis) and patient-initiated disenrollment (revocation). Hospice, regional, and patient risk factors and variation were assessed with multilevel mixed-effects logistic regression models.

RESULTS

Among 867,695 hospice enrollees with dementia, 70,945 (8.2%) were disenrolled due to extended prognosis and 43,133 (5.0%) revoked within 1-year of their index admission. There was substantial variation in hospice provider disenrollment due to extended prognosis (10th-90th percentile 4.5%-14.6%, adjusted median odds ratio (MOR) 1.86, 95% confidence interval (CI) 1.82, 1.91) and revocation (10th-90th percentile 2.5%-10.1%, MOR 2.09, 95% CI 2.03, 2.14). Among hospital referral regions (HRR), there was more variation in revocation (10th-90th percentile 3.5%-7.6%, MOR 1.4, 95% CI 1.34, 1.47) than extended prognosis (10th-90th percentile 7.0%-9.5%, MOR 1.23, 95% CI 1.18, 1.27), with much higher revocation rates noted in HRRs located in the Southeast and Southern California. A number of patient and hospice characteristics were associated with higher odds of both types of disenrollment (younger age, female sex, minoritized race and ethnicity, Medicaid dual eligibility, Medicare Part C enrollment), while some were associated with revocation only (more comorbidities, newer, smaller, and for-profit hospices).

CONCLUSIONS

In this nationally representative study of hospice enrollees with dementia, hospice disenrollment varied by type of hospice, geographic region, and patient characteristics including age, sex, race, and ethnicity. These findings raise important questions about whether and how the Medicare Hospice Benefit could be adapted to reduce disparities and better support PWD.

Palliative Care in Advanced Alzheimer's Disease Dementia: Evaluation of the Answers Given by Caregivers and Physicians to the Accuracy of Surprise Question, as a Prognostic Tool

Introduction: Alzheimer's disease (AD) dementia is the sixth leading cause of death in the United States. The surprise question (SQ) "Would you be surprised if this patient were to die within the next 12 months?" was used to identify death-risk patients, who could benefit from palliative care. Objective: To examine the prognostic accuracy of the SQ by physicians and caregivers in outpatients with AD dementia. Methods: This is a longitudinal and prospective study involving 101 patients along 1 year, applying the SAS 9.2 software and adopting a .05 P-value to assess the variables that influenced answers to the accuracy of SQ using the chi-square test. Results: 27 patients (26.7%) died during the follow-up. When caregivers answered the SQ, it presented a 51.8% sensitivity (CI 31.9 - 71.3), a 66.7% negative predictive value (20.7 - 63.6), a 56.2% specificity (CI 29.8 - 80.2), and a 40.9% positive predictive value of (CI 43.0 - 85.4) with a 53.4% accuracy (CI 38.5 - 68.4). When physicians answered, the SQ had an 88.8% sensitivity (CI 70.8 - 97.6), a 40% negative predictive value (CI 5.2 - 85.3), a 12.5% specificity (CI 1.5 - 38.3), a 63.1% positive predictive value (CI 45.9 - 78.1) with a 60.4% accuracy (CI 45.8 - 75). Conclusion: SQ remains a good tool with high sensitivity for the identification of patients with advanced AD dementia when presented to the attending physician for planning palliative advanced care with accuracy of 60.4% and caregivers' accuracy of 53.4%.

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.

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.

Impact of Comorbid Dementia on Patterns of Hospice Use

Background: The evidence base for understanding hospice use among persons with dementia is almost exclusively based on individuals with a primary terminal diagnosis of dementia. Little is known about whether comorbid dementia influences hospice use patterns. Objective: To estimate the prevalence of comorbid dementia among hospice enrollees and its association with hospice use patterns. Design: Pooled cross-sectional analysis of the nationally representative Health and Retirement Study (HRS) linked to Medicare claims. Subjects: Fee-for-service Medicare beneficiaries in the United States who enrolled with hospice and died between 2004 and 2016. Measurements: Dementia was assessed using a validated survey-based algorithm. Hospice use patterns were enrollment less than or equal to three days, enrollment greater than six months, hospice disenrollment, and hospice disenrollment after six months. Results: Of 3123 decedents, 465 (14.9%) had a primary hospice diagnosis of dementia and 943 (30.2%) had comorbid dementia and died of another illness. In fully adjusted models, comorbid dementia was associated with increased odds of hospice enrollment greater than six months (adjusted odds ratio [AOR] = 1.52, 95% confidence interval [CI]: 1.11-2.09) and hospice disenrollment following six months of hospice (AOR = 2.55, 95% CI: 1.43-4.553). Having a primary diagnosis of dementia was associated with increased odds of hospice enrollment greater than six months (AOR = 2.62, 95% CI: 1.86-3.68), hospice disenrollment (AOR = 1.82, 95% CI: 1.32-2.51), and hospice disenrollment following six months of hospice (AOR = 4.31, 95% CI: 2.37-7.82). Conclusion: Approximately 45% of the hospice population has primary or comorbid dementia and are at increased risk for long hospice enrollment periods and hospice disenrollment. Consideration of the high prevalence of comorbid dementia should be inherent in hospice staff training, quality metrics, and Medicare Hospice Benefit policies.

Palliative care for patients with advanced dementia

ABSTRACT

Dementia is currently the seventh leading cause of death and one of the major causes of disability and dependency among older adults globally. Its final stages are complicated by a multitude of problems that can cause immense suffering. This article explores the interconnection between advanced dementia and palliative care and the role of nurses in providing end-of-life care for these patients.

Emotion work and feeling rules: Coping strategies of family caregivers of people with end stage dementia in Israel-A qualitative study

Background

End stage dementia is an inevitable phase following a prolonged deterioration. Family caregivers for people with end stage dementia who live in their home can experience an emotional burden. Emotion work and “feeling-rules” refers to socially shared norms and self-management of feelings, as well as projecting emotions appropriate for the situation, aiming at achieving a positive environment as a resource for supporting others’ wellbeing.

Objectives

Exploring and describing the experience of family caregivers of people with end stage dementia at home, in Israel, unpacking their emotional coping and the emotional-strategies they use, and placing family caregivers' emotion work in a cultural context.

Method

We conducted fifty qualitative interviews using semi structured interviews analyzed through a thematic content analysis approach.

Findings

Four characteristics of emotion work were identified: (1) sliding between detachment and engagement, (2) separating the person from their condition (3), adoption of caregiving as a social role and a type of social reinforcement, and (4) using the caregiving role in coping with loneliness and emptiness. The emotional coping strategies are culturally contextualized, since they are influenced by the participants’ cultural background.

Discussion

This article’s focus is transparent family caregivers' emotion work, a topic which has rarely been discussed in the literature is the context of caring for a family member with dementia at home. In our study, emotion work appears as a twofold concept: the emotion work by itself contributed to the burden, since family caregivers' burden experience can evolve from the dissonance between their “true” feelings of anger and frustration and their expected “acceptable” feelings (“feeling-rules”) formed by cultural norms. However, emotion work was also a major source of coping and finding strength and self-meaning. Understanding and recognizing the emotion work and the cultural and religious influence in this coping mechanism can help professionals who treat people with end stage dementia to better support family-caregivers.

Delivery models of neuropalliative care

Drawing its beginnings from end-of-life care, palliative care has developed into a specialized interdisciplinary effort aiming to alleviate distress in all its form, and spanning the whole serious illness trajectory. With this evolution came the inevitable expansion to different sites and modes of care delivery. This section discusses the various models of bringing palliative care to patients with neurologic illness. It begins by distinguishing primary from specialist palliative care, then examines various models of inpatient and outpatient care. Hospital-based models include consultation service and dedicated inpatient units, while outpatient care mainly consists of palliative care specialists embedded in disease-specific clinics. Home-based palliative care and services provided through telemedicine are discussed. Hospice, a model of care often associated with end-of-life palliative care is detailed, together with suggestions on when to consider transitioning to hospice care. It is worth noting that there is not a single best model of palliative care delivery for persons living with neurologic illness. The models discussed in this chapter are complementary not competing and should be adopted by clinicians to fit the needs of patients and caregivers, the resources available in the healthcare system, and based on where patients are in the spectrum of their illness.

Predictors of Mortality in Individuals with Dementia in the National Alzheimer's Coordinating Center

BACKGROUND

Dementia is one of the top causes of death worldwide, but individuals with dementia and their caregivers report that knowing what to expect, including regarding approaching end of life, is an unmet need.

OBJECTIVE

To identify predictors of death in individuals with Alzheimer disease (AD) dementia, Lewy body dementia (LBD), vascular dementia, and frontotemporal dementia.

METHODS

The study used data from National Alzheimer's Coordinating Center participants with dementia and an etiologic diagnosis of AD, Lewy body disease, frontotemporal lobar degeneration (FTLD, with or without motor neuron disease), or vascular dementia. Analyses included median survival across dementia types and predictors of death at 5 years based on baseline demographics and clinical measure performance. Five-year survival probability tables were stratified by predictor values.

RESULTS

Individuals with AD had the longest survival (median 6 years), followed by FTLD (5 years), and vascular dementia and LBD (each 4 years). The strongest predictors of death for the full cohort were dementia type (higher risk with non-AD dementias), sex (higher risk with male sex), and race and ethnicity (higher risk with white and non-Hispanic participants). Age was associated with higher mortality risk across the non-Alzheimer dementias; other significant associations included worse cognitive status (FTLD, LBD) and more depression (LBD).

CONCLUSION

Results can help clinicians counsel individuals with dementia and families regarding average dementia trajectories; findings regarding individual risk factors can aid individualizing expectations. Further research is needed to investigate drivers of mortality in the non-AD dementias to improve counseling and help identify potentially modifiable factors.

Prognostication in dementia

Dementia is a progressive, irreversible illness and leading global cause of death defined by cognitive and subsequent functional decline. Current treatments have limited impact on mortality. In this chapter, we discuss the trajectory of dementia and its variability, markers associated with poorer prognosis (such as poor nutrition, pneumonia, comorbid conditions), the impact of hospitalization on prognosis, and current models of end-of-life palliative care/hospice eligibility (with the use of the Functional Assessment Staging tool and other markers). We then discuss strategies to discuss prognosis with patients and their healthcare proxies using a mental model (Ask, Discover, Anticipate, Provide, Track: ADAPT) and specific skills. Because of progression of dementia variability, prognosis is better discussed in terms of function. For patients with dementia, initiating advance care planning earlier in their disease course allows for more patient involvement (such as to identify a surrogate decision maker).

Accuracy of two prognostic indexes to predict mortality in older adults with advanced dementia

Dementia is a cause of disability among older adults. Accessing advanced dementia prognosis is a challenge.

Discontinuation of beta-blockers among nursing home residents at end of life

BACKGROUND

Given limited life expectancy of nursing home (NH) residents, harms of continuing beta-blockers (BBs) may outweigh clinical benefits. Our objective was to describe beta-blocker discontinuation for NH residents during the last year of life, and identify characteristics associated with earlier discontinuation.

METHODS

This was a retrospective cohort study that included all long-stay residents in fee-for-service Medicare who died in 2016 and were prescribed oral BBs 1 year before death. Beta-blocker discontinuation was defined as a gap in medication on hand for ≥45 days per Medicare Part D claims, measured from the last date drug was on hand. Comorbidities were obtained from Chronic Condition Warehouse, and other characteristics from the Minimum Data Set. Kaplan-Meier curves were used to describe time to first discontinuation. Findings were stratified by cardiac diagnoses, perceived life expectancy of <6 months, or elevated mortality index.

RESULTS

Eighty-eight thousand two hundred and eighty-four residents were prescribed ≥1 daily BB 12 months before death. Mean age was 84.1 years and 69.2% were female. Of these, 60,573 residents (68.6%) remained on a BB in the last 45 days of life, and 57,880 residents (65.6%) had ≥1 cardiac diagnosis. Only 5239 residents (5.9%) had elevated mortality index, whereas 16,798 residents (19.0%) had perceived poor prognosis. In the last year of life, there was no difference in beta-blocker discontinuation pattern between residents with and without cardiac diagnoses. Residents with perceived poor prognosis and elevated mortality index discontinued BBs earlier. For example, mean time until discontinuation among residents with poor perceived prognosis was 245 versus 279 days in residents without such prognosis (p < 0.0001).

CONCLUSIONS

BBs are commonly prescribed to NH residents in the final year of life. Overall, discontinuation occurs earlier in residents for whom clinicians perceive limited life expectancy, suggesting that improved prognostication may offer an important opportunity to reduce polypharmacy toward end of life.

Primary Palliative Care in Dementia

Primary palliative care is a fundamental aspect of high-quality care for patients with a serious illness such as dementia. The clinician caring for a patient and family suffering with dementia can provide primary palliative care in numerous ways. Perhaps the most important aspects are high quality communication while sharing a diagnosis, counseling the patient through progression of illness and prognostication, and referral to hospice when appropriate. COVID-19 presents additional risks of intensive care requirement and mortality which we must help patients and families navigate. Throughout all of these discussions, the astute clinician must monitor the patient's decision making capacity and balance respect for autonomy with protection against uninformed consent. Excellent primary palliative care also involves discussion of deprescribing medications of uncertain benefit such as long term use of cholinesterase inhibitors and memantine and being vigilant in the monitoring of pain with its relationship to behavioral disturbance in patients with dementia. Clinicians should follow a standardized approach to pain management in this vulnerable population. Caregiver burden is high for patients with dementia and comprehensive care should also address this burden and implement reduction strategies. When these aspects of care are particularly complex or initial managements strategies fall short, palliative care specialists can be an important additional resource not only for the patient and family, but for the care team struggling to guide the way through a disease with innumerable challenges.

Mortality in hospitalised older patients: the WHALES short-term predictive score

OBJECTIVE

To develop and validate the WHALES screening tool predicting short-term mortality (3 months) in older patients hospitalised in an acute geriatric unit.

METHODS

Older patients transferred to an acute geriatric ward from June 2017 to December 2018 were included. The cohort was divided into two groups: derivation (n=664) and validation (n=332) cohorts. Cause for admission in emergency room, hospitalisation history within the previous year, ongoing medical conditions, cognitive impairment, frailty status, living conditions, presence of proteinuria on a urine strip or urine albumin-to-creatinine ratio and abnormalities on an ECG were collected at baseline. Multiple logistic regressions were performed to identify independent variables associated with mortality at 3 months in the derivation cohort. The prediction score was then validated in the validation cohort.

RESULTS

Five independent variables available from medical history and clinical data were strongly predictive of short-term mortality in older adults including age, sex, living in a nursing home, unintentional weight loss and self-reported exhaustion. The screening tool was discriminative (C-statistic=0.74 (95% CI: 0.67 to 0.82)) and had a good fit (Hosmer-Lemeshow goodness-of-fit test (X2 (3)=0.55, p=0.908)). The area under the curve value for the final model was 0.74 (95% CI: 0.67 to 0.82).

CONCLUSIONS AND IMPLICATIONS

The WHALES screening tool is a short and rapid tool predicting 3-month mortality among hospitalised older patients. Early identification of end of life may help appropriate timing and implementation of palliative care.

Ethical challenges in end-stage dementia: Perspectives of professionals and family care-givers

BACKGROUND

In Israel, caring for people with end-stage dementia confined to home is mainly done by home care units, and in some cases by home hospice units, an alternative palliative-care service. Because life expectancy is relatively unknown, and the patient's decision-making ability is poor, caring for this unique population raises ethical dilemmas regarding when to define the disease as having reached a terminal stage, as well as choosing between palliative and life-prolonging-oriented care.

OBJECTIVES

Exploring and describing differences and similarities of professional staff members' (PSMs') and family caregivers' perceptions of caring for people with end-stage dementia in two different settings.

DESIGN

Qualitative research, using semi-structured interviews analyzed through a thematic content-analysis approach.

PARTICIPANTS

Sixty-four interviews were conducted (24 PSMs and 40 family caregivers) in two care-settings-home hospice unit and home care unit.

ETHICAL CONSIDERATIONS

The study was approved by the Ethics Committee (BBL00118-17).

FINDINGS

We found dilemmas regarding palliative care to be the main theme, including definition of the disease as terminal, choosing "comfort" over "life-prolonging," clarifying patients' wishes and deciding whether or not to use artificial feeding.

DISCUSSION

Both PSMs and family caregivers deal with ethical dilemmas and have reached different conclusions, both legitimate. Comprehending dementia as a terminal disease influenced participants' perceptions of the relevancy of palliative care for people with end-stage dementia. Discrepancies between PSMs and family caregivers in caring for people with end-stage dementia were found in both home hospice unit and home care unit environments, raising potential conflicts regarding decisions for end-of-life care.

CONCLUSIONS

Communication between PSMs and family caregivers is crucial for the discussion about the discrepancies regarding the unique dilemmas of caring for people with end-stage dementia and bridging the gap between them. Lack of communication and resources can hamper the provision of an acceptable solution for quality and equality of care in the best interest of people with end-stage dementia.

Mortality Risk Models for Persons with Dementia: A Systematic Review

BACKGROUND

Persons with dementia have higher mortality than the general population. Objective, standardized predictions of mortality risk in persons with dementia could help with planning resources for care close to the end of life.

OBJECTIVE

To systematically review prediction models for risk of death in persons with dementia.

METHODS

The Medline and PsycInfo databases were searched on November 29, 2020, for prediction models estimating the risk of death in persons with dementia. Study quality was assessed using the Prediction model Risk Of Bias ASsessment Tool.

RESULTS

The literature search identified 2,828 studies, of which 18 were included. These studies described 16 different prediction models with c statistics mostly ranging from 0.67 to 0.79. Five models were externally validated, of which four were applicable. There were two models that were both applicable and had reasonably low risk of bias. One model predicted risk of death at six months in persons with advanced dementia residing in a nursing home. The other predicted risk of death at three years in persons seen in primary care practice or a dementia specialty clinic, derived from a nationwide registry in Sweden but not externally validated.

CONCLUSION

Valid, applicable models with low risk of bias were found in two settings: advanced dementia in a nursing home and outpatient practices. The outpatient model requires external validation. Better models are needed for persons with mild to moderate dementia in nursing homes, a common demographic. These models may be useful for educating persons living with dementia and care partners and directing resources for end of life care.Registration:The study protocol is registered on PROSPERO as RD4202018076.

Top Ten Tips Palliative Care Clinicians Should Know About Prognostication in Oncology, Dementia, Frailty, and Pulmonary Diseases

Prognostication has been described as "Medicine's Lost Art." Taken with diagnosis and treatment, prognostication is the third leg on which medical care rests. As research leads to additional beneficial treatments for vexing conditions like cancer, dementia, and lung disease, prognostication becomes even more difficult. This article, written by a group of palliative care clinicians with backgrounds in geriatrics, pulmonology, and oncology, aims to offer a useful framework for consideration of prognosis in these conditions. This article will serve as the first in a three-part series on prognostication in adults and children.

Ethical Considerations in Dementia Diagnosis and Care: AAN Position Statement

Alzheimer disease and other dementias present unique practical challenges for patients, their families, clinicians, and health systems. These challenges reflect not only the growing public health effect of dementia in an aging global population, but also more specific ethical complexities including early loss of patients' capacity to make decisions regarding their own care, the stigma often associated with a dementia diagnosis, the difficulty of balancing concern for patients' welfare with respect for patients' remaining independence, and the effect on the physical, emotional, and financial well-being of family caregivers. Caring for patients with dementia requires respecting patient autonomy while acknowledging progressively diminishing decisional capacity and continuing to provide care in accordance with other core ethical principles (beneficence, justice, and nonmaleficence). Whereas these ethical principles remain unchanged, neurologists must reconsider how to apply them given changes across multiple domains including our understanding of disease, clinical and legal tools for addressing manifestations of illness, our expanding awareness of the crucial role of family caregivers in providing care and maintaining patient quality of life, and societal conceptions of dementia and individuals' personal expectations for aging. This revision to the American Academy of Neurology's 1996 position statement summarizes ethical considerations that often arise in caring for patients with dementia; although it addresses how such considerations influence patient management, it is not a clinical practice guideline.

Palliative Care: Critical Concepts for the Geropsychiatrist

Psychiatrists can make a significant contribution to improving quality end-of-life care for psychiatric patients, beyond managing their psychiatric and psychological conditions. Geriatric psychiatrists can build expertise in enhancing end-of-life care when caring for older adults with serious illnesses and their families, given the biopsychosociospiritual approach that significantly overlaps with palliative and hospice care approaches. To effectively add quality to end-of-life care, it is essential for psychiatrists to understand the core principles and practices of palliative and hospice care, learn basic symptom management skills, and hone the ability to have crucial conversations regarding prognosis and advance care planning. Also important is recognizing when to refer to hospice and palliative medicine subspecialists. This article provides an overview of palliative and hospice care, uses a case study to illustrate components of palliative and hospice care relevant to geriatric psychiatry practice, and comments on considerations pertinent to the coronavirus disease 2019 (COVID-19) pandemic.

Genotype Load Modulates Amyloid Burden and Anxiety-Like Patterns in Male 3xTg-AD Survivors despite Similar Neuro-Immunoendocrine, Synaptic and Cognitive Impairments

The wide heterogeneity and complexity of Alzheimer’s disease (AD) patients’ clinical profiles and increased mortality highlight the relevance of personalized-based interventions and the need for end-of-life/survival predictors. At the translational level, studying genetic and age interactions in a context of different levels of expression of AD-genetic-load can help to understand this heterogeneity better. In the present report, a singular cohort of long-lived (19-month-old survivors) heterozygous and homozygous male 3xTg-AD mice were studied to determine whether their AD-genotype load can modulate the brain and peripheral pathological burden, behavioral phenotypes, and neuro-immunoendocrine status, compared to age-matched non-transgenic controls. The results indicated increased amyloid precursor protein (APP) levels in a genetic-load-dependent manner but convergent synaptophysin and choline acetyltransferase brain levels. Cognitive impairment and HPA-axis hyperactivation were salient traits in both 3xTg-AD survivor groups. In contrast, genetic load elicited different anxiety-like profiles, with hypoactive homozygous, while heterozygous resembled controls in some traits and risk assessment. Complex neuro-immunoendocrine crosstalk was also observed. Bodyweight loss and splenic, renal, and hepatic histopathological injury scores provided evidence of the systemic features of AD, despite similar peripheral organs’ oxidative stress. The present study provides an interesting translational scenario to study further genetic-load and age-dependent vulnerability/compensatory mechanisms in Alzheimer’s disease.

Advanced Dementia: Brain-State Characteristics and Clinical Indicators of Early Mortality

There is an urgent need in advanced dementia for evidence-based clinical prognostic predictors that could positively influence ethical decisions allowing health provider and family preparation for early mortality. Accordingly, the authors review and discuss the prognostic utility of clinical assessments and objective measures of pathological brain states in advanced dementia patients associated with accelerated mortality. Overall, due to the paucity of brain-activity and clinical-comorbidity predictors of survival in advanced dementia, authors outline the potential prognostic value of brain-state electroencephalography (EEG) measures and reliable clinical indicators for forecasting early mortality in advanced dementia patients. In conclusion, two consistent risk-factors for predicting accelerated mortality in terminal-stage patients with advanced dementia were identified: pressure ulcers and paroxysmal slow-wave EEG parameters associated with cognitive impairment severity and organic disease progression. In parallel, immobility, malnutrition, and co-morbid systemic diseases are highly associated with the risk for early mortality in advanced dementia patients. Importantly, the authors' conclusions suggest utilizing reliable quantitative-parameters of disease progression for estimating accelerated mortality in dementia patients entering the terminal disease-stages characterized by severe intellectual deficits and functional disability.

Protocol for an observational cohort study identifying factors predicting accurately end of life in dementia with Lewy bodies and promoting quality end-of-life experiences: the PACE-DLB study

INTRODUCTION

Dementia with Lewy bodies (DLB) is one of the most common degenerative dementias. Despite the fact that most individuals with DLB die from complications of the disease, little is known regarding what factors predict impending end of life or are associated with a quality end of life.

METHODS AND ANALYSIS

This is a multisite longitudinal cohort study. Participants are being recruited from five academic centres providing subspecialty DLB care and volunteers through the Lewy Body Dementia Association (not receiving specialty care). Dyads must be US residents, include individuals with a clinical diagnosis of DLB and at least moderate-to-severe dementia and include the primary caregiver, who must pass a brief cognitive screen. The first dyad was enrolled 25 February 2021; recruitment is ongoing. Dyads will attend study visits every 6 months through the end of life or 3 years. Study visits will occur in-person or virtually. Measures include demographics, DLB characteristics, caregiver considerations, quality of life and satisfaction with end-of-life experiences. For dyads where the individual with DLB dies, the caregiver will complete a final study visit 3 months after the death to assess grief, recovery and quality of the end-of-life experience. Terminal trend models will be employed to identify significant predictors of approaching end of life (death in the next 6 months). Similar models will assess caregiver factors (eg, grief, satisfaction with end-of-life experience) after the death of the individual with DLB. A qualitative descriptive analysis approach will evaluate interview transcripts regarding end-of-life experiences.

ETHICS AND DISSEMINATION

This study was approved by the University of Florida institutional review board (IRB202001438) and is listed on clinicaltrials.gov (NCT04829656). Data sharing follows National Institutes of Health policies. Study results will be disseminated via traditional scientific strategies (conferences, publications) and through collaborating with the Lewy Body Dementia Association, National Institute on Aging and other partnerships.

Practices, challenges, and opportunities when addressing the palliative care needs of people living with dementia: Specialty memory care provider perspectives

INTRODUCTION

Palliative care focuses on reducing suffering and improving quality of life for individuals with serious illness and their families. In an effort to develop palliative care interventions for specialty memory care clinics, this study characterizes memory care providers' perspectives on addressing palliative care needs of people living with dementia (PLWD).

METHODS

Qualitative interviews with specialty memory care providers were followed by thematic analysis by a multidisciplinary research team.

RESULTS

Provider approaches overlap with key domains of palliative care. Approaches unique to dementia include having a detailed understanding of dementia syndromes, behavioral symptoms, and caregiver burden. Challenges were identified related to disease progression, provider-level factors, and systems and cultural issues. Respondents identified training needed to strengthen a palliative care approach.

DISCUSSION

There are many strengths of using memory care teams to address palliative care needs of PLWD. However, they may require additional knowledge and training to strengthen their work.

Palliative Care in Movement Disorders: an Evolving Field

PURPOSE OF REVIEW

This review summarizes the current state of evidence for palliative care (PC) in movement disorders, describes the application of PC to clinical practice, and suggests future research directions.

RECENT FINDINGS

PC needs are common in persons living with movement disorders and their families from the time of diagnosis through end-of-life and contribute to quality of life. Early advance care planning is preferred by patients, impacts outcomes and is promoted by PC frameworks. Systematic assessment of non-motor symptoms, psychosocial needs and spiritual/existential distress may address gaps in current models of care. Several complementary and emerging models of PC may be utilized to meet the needs of this population. A PC approach may identify and improve important patient and caregiver-centered outcomes. As a relatively new application of PC, there is a need for research to adapt, develop and implement approaches to meet the unique needs of this population.

Sex-Dependent End-of-Life Mental and Vascular Scenarios for Compensatory Mechanisms in Mice with Normal and AD-Neurodegenerative Aging

Life expectancy decreases with aging, with cardiovascular, mental health, and neurodegenerative disorders strongly contributing to the total disability-adjusted life years. Interestingly, the morbidity/mortality paradox points to females having a worse healthy life expectancy. Since bidirectional interactions between cardiovascular and Alzheimer’s diseases (AD) have been reported, the study of this emerging field is promising. In the present work, we further explored the cardiovascular–brain interactions in mice survivors of two cohorts of non-transgenic and 3xTg-AD mice, including both sexes, to investigate the frailty/survival through their life span. Survival, monitored from birth, showed exceptionally worse mortality rates in females than males, independently of the genotype. This mortality selection provided a “survivors” cohort that could unveil brain–cardiovascular interaction mechanisms relevant for normal and neurodegenerative aging processes restricted to long-lived animals. The results show sex-dependent distinct physical (worse in 3xTg-AD males), neuropsychiatric-like and cognitive phenotypes (worse in 3xTg-AD females), and hypothalamic–pituitary–adrenal (HPA) axis activation (higher in females), with higher cerebral blood flow and improved cardiovascular phenotype in 3xTg-AD female mice survivors. The present study provides an experimental scenario to study the suggested potential compensatory hemodynamic mechanisms in end-of-life dementia, which is sex-dependent and can be a target for pharmacological and non-pharmacological interventions.

Dementia and Early Do-Not-Resuscitate Orders Associated With Less Intensive of End-of-Life Care: A Retrospective Cohort Study

BACKGROUND

Dementia is a leading cause of death among US older adults. Little is known about end-of-life care intensity and do-not-resuscitate orders (DNRs) among patients with dementia who die in hospital.

AIM

Examine the relationship between dementia, DNR timing, and end-of-life care intensity.

DESIGN

Observational cohort study.

SETTING/PARTICIPANTS

Inpatient electronic health record extraction for 2,566 persons age 65 and older who died in 2 New York City hospitals in the United States from 2015 to 2017.

RESULTS

Multivariable logistic regression analyses modeled associations between dementia diagnosis, DNR timing, and 6 end-of-life care outcomes. 31% of subjects had a dementia diagnosis; 23% had a DNR on day of hospital admission. Patients with dementia were 18%-40% less likely to have received 4 of 6 types of intensive care (mechanical ventilation AOR: 0.82, 95%CI: 0.67 -1.00; intensive care unit admission AOR: 0.60, 95%CI: 0.49-0.83). Having a DNR on file was inversely associated with staying in the intensive care unit (AOR: 0.57, 95%CI: 0.47-0.70) and avoiding other intensive care measures. DNR placement later during the hospitalization and not having a DNR were associated with more intensive care compared to having a DNR upon admission.

CONCLUSIONS

Having dementia and a do-not resuscitate order upon hospital admission are associated with less intensive end-of-life care. Additional research is needed to understand why persons with dementia receive less intensive care. In clinical practice, encouraging advance care planning prior to and at hospital admission may be particularly important for patients wishing to avoid intensive end-of-life care, including patients with dementia.
