Comorbid health conditions and their impact on social isolation, loneliness, quality of life, and well-being in people with dementia: longitudinal findings from the IDEAL programme. BMC Geriatr 2024; 24:23. [PMID: 38182985 PMCID: PMC10768096 DOI: 10.1186/s12877-023-04601-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2023] [Accepted: 12/14/2023] [Indexed: 01/07/2024] Open
Abstract
BACKGROUND Most people with dementia have multiple health conditions. This study explores (1) number and type of health condition(s) in people with dementia overall and in relation to age, sex, dementia type, and cognition; (2) change in number of health conditions over two years; and (3) whether over time the number of health conditions at baseline is related to social isolation, loneliness, quality of life, and/or well-being. METHODS Longitudinal data from the IDEAL (Improving the experience of Dementia and Enhancing Active Life) cohort were used. Participants comprised people with dementia (n = 1490) living in the community (at baseline) in Great Britain. Health conditions using the Charlson Comorbidity Index, cognition, social isolation, loneliness, quality of life, and well-being were assessed over two years. Mixed effects modelling was used. RESULTS On average participants had 1.8 health conditions at baseline, excluding dementia; increasing to 2.5 conditions over two years. Those with vascular dementia or mixed (Alzheimer's and vascular) dementia had more health conditions than those with Alzheimer's disease. People aged ≥ 80 had more health conditions than those aged < 65 years. At baseline having more health conditions was associated with increased loneliness, poorer quality of life, and poorer well-being, but was either minimally or not associated with cognition, sex, and social isolation. Number of health conditions had either minimal or no influence on these variables over time. CONCLUSIONS People with dementia in IDEAL generally had multiple health conditions and those with more health conditions were lonelier, had poorer quality of life, and poorer well-being.

ALZHEIMER'S & DEMENTIA (AMSTERDAM, NETHERLANDS) 2024; 16:e12541. [PMID: 38288266 PMCID: PMC10823153 DOI: 10.1002/dad2.12541] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/02/2023] [Revised: 12/06/2023] [Accepted: 01/02/2024] [Indexed: 01/31/2024]
Abstract
INTRODUCTION We investigated whether mortality in memory clinic patients changed due to coronavirus disease 2019 (COVID-19) pandemic. METHODS We included patients from the Amsterdam Dementia Cohort: (1) n = 923 pandemic patients (baseline visit: 2017-2018, follow-up: until 2021), and (2) n = 830 historical control patients (baseline visit: 2015-2016, follow-up: until 2019). Groups were well-balanced. We compared mortality during pandemic with historical control patients using Cox regression. Differences in cause of death between groups were explored using Fisher's exact test. RESULTS Pandemic patients had a higher risk of mortality than historical control patients (hazard ratio [HR] [95% confidence interval {CI}] = 1.34 [1.05-1.70]). Stratified for syndrome diagnosis, the effect remained significant in dementia patients (HR [95% CI] = 1.35 [1.03-1.78]). Excluding patients who died of COVID-19-infection, the higher mortality risk in pandemic patients attenuated (HR [95% CI] = 1.24 [0.97-1.58]). Only the difference in cause of death between pandemic patients and historical control patients for death to COVID-19-infection (p = 0.001) was observed. CONCLUSION Memory clinic patients had increased mortality risk during COVID-19 compared to historical control patients, attributable to dementia patients. Highlights We investigated if mortality rates in memory clinic patients changed due to COVID-19 pandemic.We included patients along the cognitive continuum, including SCD, MCI, and dementia.We used a well-balanced historical control group.Memory clinic patients had higher risk for mortality during COVID-19 lockdown.Our results indicate that excess mortality is mainly caused by death to COVID-19 infection.

Abstract
BACKGROUND AND PURPOSE Dementia prevalence is increasing, with numbers projected to double by 2050. Risk factors for its development include age and cardiovascular comorbidities, which are found more often in patients with dementia and should be treated properly to improve outcomes. In this case-control study, we analysed a large population-based prescription database to explore the patterns of co-medication in patients with dementia. METHODS Prescription claims covering >99% of the Austrian population from 2005 to 2016 were obtained. Patients who were treated with an approved antidementia drug (ADD) were included and co-medication exposure was recorded. A group of people not taking ADDs was matched for age, sex and follow-up duration as a control. RESULTS We included 70,799 patients on ADDs who were exposed to a mean of 5.3 co-medications while control patients were treated with a total of 5.2 co-medications (p < 0.001). We found that patients on ADDs received less somatic (4.1 vs. 4.5) but more psychiatric medication (1.1 vs. 0.6; p < 0.001 for both). Patients on ADDs were less likely to be treated for pain, cardiovascular conditions or hyperlipidemia. More than 50% of patients on ADDs were treated with antidepressants or antipsychotics. Greater number of co-medications was associated with markers of more intensive antidementia treatment. CONCLUSION Patients on ADDs received more medications overall but were less frequently treated for somatic conditions known to be more prevalent in this group. Together, our data suggest that management of comorbidities in dementia could be improved to optimize outcome and quality of life.

Prevalence of Comorbid Depression and Insomnia Among Veterans Hospitalized for Heart Failure with Alzheimer Disease and Related Disorders. Am J Geriatr Psychiatry 2023; 31:428-437. [PMID: 36863973 DOI: 10.1016/j.jagp.2023.01.026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/25/2022] [Revised: 01/23/2023] [Accepted: 01/24/2023] [Indexed: 02/10/2023]
Abstract
OBJECTIVE To examine prevalence of Alzheimer Disease and related dementias (ADRD) and patient characteristics as a function of comorbid insomnia and/or depression among heart failure (HF) patients discharged from hospitals. DESIGN Retrospective cohort descriptive epidemiology study. SETTING VA Hospitals. PARTICIPANTS N = 373,897 Veterans hospitalized with heart failure from October 1, 2011 until September 30, 2020. MEASUREMENTS We examined VA and Center for Medicare & Medicaid Services (CMS) coding in the year prior to admission using published ICD-9/10 codes for dementia, insomnia, and depression. The primary outcome was the prevalence of ADRD and the secondary outcomes were 30-day and 365-day mortality. RESULTS The cohort were predominantly older adults (mean age = 72 years, SD = 11), male (97%), and White (73%). Dementia prevalence in participants without insomnia or depression was 12%. In those with both insomnia and depression, dementia prevalence was 34%. For insomnia alone and depression alone, dementia prevalence was 21% and 24%, respectively. Mortality followed a similar pattern with highest 30-day and 365-day mortality higher in those with both insomnia and depression. CONCLUSIONS These results suggest that persons with both insomnia and depression are at an increased risk of ADRD and mortality compared to persons with one or neither condition. Screening for both insomnia and depression, especially in patients with other ADRD risk factors, could lead to earlier identification of ADRD. Understanding comorbid conditions which may represent earlier signs of ADRD may be critical in the identification of ADRD risk.

Abstract
Limited research is available on the real-world experiences of patients with dementia with Lewy bodies (DLB). This study evaluated clinical events, healthcare utilization, and healthcare costs of patients with DLB vs other dementia types with psychosis (ODP). Study patients included commercial and Medicare Advantage with Part D enrollees aged ≥40 years with evidence of DLB and ODP from 6/01/2015‒5/31/2019. Compared with patients with ODP, more patients with DLB had clinical events including anticholinergic effects, neurologic effects, and cognitive decline. Patients with DLB used more healthcare resources with greater dementia-related office and outpatient visits and psychosis-related inpatient stays and office, outpatient, and emergency visits compared with their ODP patient counterparts. Patients with DLB also incurred higher healthcare costs for all-cause and dementia-related office visits and pharmacy fills, and psychosis-related total costs. Understanding the clinical and economic impact of DLB and ODP is important to improve care for patients with dementia.

Abstract
UNLABELLED A decline in cognitive performance has been associated with disease severity, exacerbations rate, presence of comorbidities, and low activity level in people with chronic obstructive pulmonary disease (COPD). Participation in exercise programs appears to have neuroprotective effects and to improve cognitive performance in older people. The present work undertook a scoping review of the effects of exercise-based interventions on cognitive function in older individuals with stable COPD. METHODS The methodological framework for scoping review was used and electronic searches of five databases performed. Original research and observational studies published between January 2010 and December 2021, administering exercise-based interventions and cognitive function evaluation, were included. RESULTS Of 13 full-text manuscripts assessed for eligibility, five were allocated to analysis. Three studies administered exercise training within pulmonary outpatient rehabilitation program (PR), and one inpatient PR. The fifth study conducted a structured training intervention in which either aerobic or a combination with resistance exercises were included. Twelve cognitive function screening tools were used in the five studies included in the analysis. Results extracted were based on 245 COPD (33% female) with moderate to very-severe airflow limitation. Interventions ranged from 12 to 36 sessions. Studies reported statistically significant improvements after intervention in different cognitive function domains, such as global cognition, immediate and delayed recall ability, cognitive flexibility, verbal fluency, attention, abstract reasoning, praxis ability. CONCLUSIONS Exercise-based interventions improve several areas of cognitive function in patients with stable COPD. However, the magnitude of gain varies among studies, and this is possibly due to the heterogeneity of tests used. Future research is needed to validate the optimal battery of screening tests, and to support the definition of guidelines for cognitive function evaluation in COPD.

Abstract
ABSTRACT Alzheimer’s disease (AD) and other neurodegenerative dementias have a progressive course, impairing cognition, functional capacity, and behavior. Most studies have focused on AD. Severe dementia is associated with increased age, higher morbidity-mortality, and rising costs of care. It is fundamental to recognize that severe dementia is the longest period of progression, with patients living for many years in this stage. It is the most heterogeneous phase in the process, with different abilities and life expectancies. This practice guideline focuses on severe dementia to improve management and care in this stage of dementia. As it is a long period in the continuum of dementia, clinical practice should consider non-pharmacological and pharmacological approaches. Multidisciplinary interventions (physical therapy, speech therapy, nutrition, nursing, and others) are essential, besides educational and support to caregivers.

Abstract
RESUMO A doença de Alzheimer (DA) e outras demências neurodegenerativas têm um curso progressivo com comprometimento da cognição, capacidade funcional e comportamento. A maioria dos estudos enfocou a DA. A demência grave está associada ao aumento da idade, maior morbimortalidade e aumento dos custos de cuidados. É fundamental reconhecer que a demência grave é o período mais longo de progressão, com o paciente vivendo muitos anos nesta fase. É a fase mais heterogênea do processo, com diferentes habilidades e expectativa de vida. Esta diretriz de prática concentra-se na demência grave para melhorar o manejo e o cuidado nessa fase da demência. Como um longo período no continuum da demência, as abordagens não farmacológicas e farmacológicas devem ser consideradas. Intervenções multidisciplinares (fisioterapia, fonoaudiologia, nutrição, enfermagem, entre outras) são essenciais, além de educacionais e de apoio aos cuidadores.

Abstract
OBJECTIVES This study aimed to examine the influence of cognitive impairment on preventive health services utilization among older adults. METHODS The study sample came from 1995 to 2014 waves of the Health and Retirement Study (HRS), consisting of 19,644 adults aged 51 years or older. Mixed-effects logistic regression was used to analyze the influence of cognitive impairment, measured using the Telephone Interview for Cognitive Status, on the utilization of four types of preventive health care services, including flu shots, cholesterol tests, mammography for women, and prostate cancer screening for men. RESULTS Persons with cognitive impairment with no dementia were less likely to receive cholesterol tests (OR=0.68, 95% CI=0.64-0.73, p<.001), flu shots (OR=0.86, CI=0.80-0.92, p<.001), mammograms (OR=0.88, CI=0.78-0.99, p<.05), and prostate cancer screenings (OR=0.71, CI=0.71-0.98, p<.05) compared with those without cognitive impairment. Having dementia was associated with a lower odds of receiving cholesterol tests (OR=0.42, CI=0.38-0.47, p<.001), flu shots (OR=0.65, CI=0.57-0.74, p<.001), mammograms (OR=0.70, CI=0.55-0.89, p<.01), and prostate cancer screening (OR=0.68, CI=0.47-0.99, p<.05). CONCLUSIONS Cognitive impairment with or without dementia is a significant barrier to utilizing preventive health services among older adults. Targeted health promotion prevention and intervention strategies and caregiver education are warranted to improve preventive services among older adults with cognitive impairment.

Abstract
Excitotoxicity is one of the primary mechanisms of cell loss in a variety of diseases of the central and peripheral nervous systems. Other than the previously established signaling pathways of excitotoxicity, which depend on the excessive release of glutamate from axon terminals or over-activation of NMDA receptors (NMDARs), Ca2+ influx-triggered excitotoxicity through Ca2+-permeable (CP)-AMPA receptors (AMPARs) is detected in multiple disease models. In this review, both acute brain insults (e.g., brain trauma or spinal cord injury, ischemia) and chronic neurological disorders, including Epilepsy/Seizures, Huntington’s disease (HD), Parkinson’s disease (PD), Alzheimer’s disease (AD), amyotrophic lateral sclerosis (ALS), chronic pain, and glaucoma, are discussed regarding the CP-AMPAR-mediated excitotoxicity. Considering the low expression or absence of CP-AMPARs in most cells, specific manipulation of the CP-AMPARs might be a more plausible strategy to delay the onset and progression of pathological alterations with fewer side effects than blocking NMDARs.

Abstract
The most common neurodegenerative dementias include Alzheimer’s disease (AD), dementia with Lewy bodies (DLB), and frontotemporal dementia (FTD). The correct etiology-based diagnosis is pivotal for clinical management of these diseases as well as for the suitable timing and choosing the accurate disease-modifying therapies when these become available. Enzyme-linked immunosorbent assay (ELISA)-based methods, detecting altered levels of cerebrospinal fluid (CSF) Tau, phosphorylated Tau, and Aβ-42 in AD, allowed the wide use of this set of biomarkers in clinical practice. These analyses demonstrate a high diagnostic accuracy in AD but suffer from a relatively restricted usefulness due to invasiveness and lack of prognostic value. In recent years, the development of novel advanced techniques has offered new state-of-the-art opportunities in biomarker discovery. These include single molecule array technology (SIMOA), a tool for non-invasive analysis of ultra-low levels of central nervous system-derived molecules from biofluids, such as CSF or blood, and real-time quaking (RT-QuIC), developed to analyze misfolded proteins. In the present review, we describe the history of methods used in the fluid biomarker analyses of dementia, discuss specific emerging biomarkers with translational potential for clinical use, and suggest an algorithm for the use of new non-invasive blood biomarkers in clinical practice.

Abstract
Background—Alzheimer’s disease (AD) is a multifactorial, progressive, neurodegenerative disease that is characterized by memory loss, personality changes, and a decline in cognitive function. While the exact cause of AD is still unclear, recent studies point to lifestyle, diet, environmental, and genetic factors as contributors to disease progression. The pharmaceutical approaches developed to date do not alter disease progression. More than two hundred promising drug candidates have failed clinical trials in the past decade, suggesting that the disease and its causes may be highly complex. Medicinal plants and herbal remedies are now gaining more interest as complementary and alternative interventions and are a valuable source for developing drug candidates for AD. Indeed, several scientific studies have described the use of various medicinal plants and their principal phytochemicals for the treatment of AD. This article reviews a subset of herbs for their anti-inflammatory, antioxidant, and cognitive-enhancing effects. Methods—This article systematically reviews recent studies that have investigated the role of neuroprotective herbs and their bioactive compounds for dementia associated with Alzheimer’s disease and pre-Alzheimer’s disease. PubMed Central, Scopus, and Google Scholar databases of articles were collected, and abstracts were reviewed for relevance to the subject matter. Conclusions—Medicinal plants have great potential as part of an overall program in the prevention and treatment of cognitive decline associated with AD. It is hoped that these medicinal plants can be used in drug discovery programs for identifying safe and efficacious small molecules for AD.

Abstract
Our study aimed at determining the economic burden of leisure-time physical inactivity in hospitalizations due to dementia in Brazil. In this national-wide descriptive study, we used secondary data from the Brazilian Health Informatics Department and from the latest Brazilian National Health Survey (2013). Rate of hospitalization and economic cost were extracted from 2013. Leisure-time physical inactivity prevalence was used to estimate its population attributable fraction for dementia. Outcomes were stratified into sex (man/woman), age groups (< 50, 50-59, 60-69, 70-79, 80+), ethnicity (white, black, mixed race, other), and region (South, Southeast, North, Northeast, and Central). In 2013, 3,724 people were hospitalized due to dementia in Brazil resulting in a total cost of BRL 17,971,833.85 (USD 7,673,973.05). More than half of cost among men was spent with individuals younger than 59 years, white and mixed-race, and from Southeast region. Proportion of cost was higher in women older than 60 years and white. In 2013, 37% of all hospitalization from dementia in Brazil were attributable to physical inactivity, with values reaching 42.9% and 43.8% for men and women aged 80 or older, respectively. Physical inactivity cost BRL 6,994,254.75 (USD 2,986,546.78) in 2013 on hospitalizations due to dementia in Brazil. Higher attributable-cost was found for patients younger than 50 years and women older than 80. Strategies to preserve the quality of life of these patients are needed to reduce the burden for the patients, their family, and on the healthcare system.

Abstract
A growing elderly population suffering from incurable, chronic conditions such as dementia present a continual strain on medical services due to mental impairment paired with high comorbidity resulting in increased hospitalization risk. The identification of at risk individuals allows for preventative measures to alleviate said strain. Electronic health records provide opportunity for big data analysis to address such applications. Such data however, provides a challenging problem space for traditional statistics and machine learning due to high dimensionality and sparse data elements. This article proposes a novel machine learning methodology: entropy regularization with ensemble deep neural networks (ECNN), which simultaneously provides high predictive performance of hospitalization of patients with dementia whilst enabling an interpretable heuristic analysis of the model architecture, able to identify individual features of importance within a large feature domain space. Experimental results on health records containing 54,647 features were able to identify 10 event indicators within a patient timeline: a collection of diagnostic events, medication prescriptions and procedural events, the highest ranked being essential hypertension. The resulting subset was still able to provide a highly competitive hospitalization prediction (Accuracy: 0.759) as compared to the full feature domain (Accuracy: 0.755) or traditional feature selection techniques (Accuracy: 0.737), a significant reduction in feature size. The discovery and heuristic evidence of correlation provide evidence for further clinical study of said medical events as potential novel indicators. There also remains great potential for adaption of ECNN within other medical big data domains as a data mining tool for novel risk factor identification.

The direct health care cost to Medicare of Down syndrome dementia as compared with Alzheimer's disease among 2015 Californian beneficiaries. Ann Phys Rehabil Med 2020; 64:101430. [PMID: 32853759 DOI: 10.1016/j.rehab.2020.07.011] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2019] [Revised: 07/05/2020] [Accepted: 07/12/2020] [Indexed: 11/21/2022]
Abstract
BACKGROUND Aging individuals with Down syndrome (DS) are at increased risk of dementia due to trisomy of chromosome 21 on which the amyloid precursor protein gene is located and with increased life expectancy. Yet, little is known about the costs associated with DS dementia and how this compares to Alzheimer's disease (AD). OBJECTIVE To better understand direct healthcare costs and care consumption in DS dementia, we compared the total cost of care to US Medicare and the drivers of these medical expenditures in individuals with DS with and without dementia, and in those with AD without DS. METHODS The effect of dementia in DS on costs and care utilization was estimated with 2015 California Medicare fee-for-service data (parts A and B). Among 3,001,977 Californian Medicare beneficiaries, 353 individuals had DS with dementia (age 45-89 years). We compared their number of chronic comorbidity conditions among 27 and their care and Medicare costs to those of age- and sex-matched individuals with DS without dementia and those with AD without DS. RESULTS Medicare annual cost per beneficiary was a mean of 43.5% and 82.2% higher with DS dementia (mean $35,011) than DS without dementia (mean $24,401) and AD without dementia (mean $19,212), related to greater utilization of inpatient services. DS dementia was associated with increased level of multimorbidity (mean of 3.4 conditions in addition to dementia vs. 2.7 and 2.2 conditions for DS without dementia and AD, respectively), with more emergency room visits (88% vs. 76.5% and 54.4%) and with more primary care physician visits (91.2% vs. 87.3% and 81.3%). CONCLUSION DS adults with dementia have higher health care costs than DS adults without dementia and adults with AD. Understanding costs and complex health care needs in DS dementia could facilitate management of adult and geriatric care resources for these high-need high-cost individuals.

Abstract
BACKGROUND Alzheimer's disease (AD) exerts a heavy burden on China. Substantial factors are found associated with high expenditure of AD in high-income countries. To date, few studies have been conducted in China. OBJECTIVE This study aimed to analyze the associated factors of the total annual costs of AD in China. METHODS Data were drawn from a multi-center, cross-sectional, socioeconomic study on the costs of AD conducted in China from October 2015 to March 2016. Generalized linear model (GLM) using gamma distribution with a log-link function was employed to examine the associated factors of the total cost. RESULTS Univariate analysis showed that the demographic and clinical characteristics of AD patients and their caregivers had a substantial impact on the total cost. In GLM analysis, age, monthly household income, AD severity, number of comorbidities, and treatment with memantine were associated with higher expenditure, while the use of a nursing home/care facility was associated with lower expenditure. The mean annual costs for patients with severe dementia were almost twice as high as those for patients with mild dementia (US$ 25,601 versus US$ 13,387, p < 0.001). The mean total cost of AD patients with at least five comorbidities (US$ 38,348) was almost three times than those with no comorbidities (US$ 13,744). CONCLUSION In China, AD severity and comorbidities were the most critical factors impacting the total cost. Optimizing care patterns, delaying disease progression, and managing comorbidities comprehensively could decrease the heavy burden of AD.

Abstract
INTRODUCTION The purpose of this study was to examine the impact of preexisting cognitive impairments on survival and medication adherence, and whether chronic medication adherence mediates or moderates the association between cognitive impairments and mortality in patients with breast cancer. METHODS This retrospective cohort study of older female patients diagnosed with breast cancer was conducted using the Surveillance, Epidemiology, and End Results Medicare Linked Database. We examined the risk of mortality from cancer and non-cancer causes in patients with and without a history of cognitive impairment. In addition, we examined if chronic medication adherence rates differ between these groups of patients and if medication adherence mediates or moderates the association between cognitive impairments and non-cancer mortality. RESULTS Mortality from cancer-specific (HR 1.13, 95% CI 1.04-1.23) and non-cancer causes (HR 1.16, 95% CI 1.11-1.21) as well as all-cause mortality (HR 1.30, 95% CI 1.23-1.38) was significantly higher in patients with cognitive impairments compared to those without cognitive impairment. Both groups showed low adherence levels to chronic medication before and after the breast cancer diagnosis. Further analysis did not show that medication adherence mediates or moderates the relationship between cognitive impairment and non-cancer mortality (p value > 0.05). CONCLUSION The results of this study indicate that older female patients with cognitive impairments and a breast cancer diagnosis have a heightened risk of cancer-specific and non-cancer mortality. Our findings do not indicate that chronic medication adherence plays a role in the association between a history of cognitive impairment and mortality, it is still necessary to further investigate this issue.

Abstract
BACKGROUND Most persons with dementia have multiple chronic conditions; however, it is unclear whether co-existing chronic conditions contribute to health-care use and cost. METHODS Persons with dementia and ≥2 chronic conditions using the National Health and Aging Trends Study and Medicare claims data, 2011 to 2014. RESULTS Chronic kidney disease and ischemic heart disease were significantly associated with increased adjusted risk ratios of annual hospitalizations, hospitalization costs, and direct medical costs. Depression, hypertension, and stroke or transient ischemic attack were associated with direct medical and societal costs, while atrial fibrillation was associated with increased hospital and direct medical costs. No chronic condition was associated with informal care costs. CONCLUSIONS Among older adults with dementia, proactive and ambulatory care that includes informal caregivers along with primary and specialty providers, may offer promise to decrease use and costs for chronic kidney disease, ischemic heart disease, atrial fibrillation, depression, and hypertension.

Abstract
OBJECTIVES To estimate the causal impact of continuity of care (COC) on total, institutional, and noninstitutional cost among community-dwelling older veterans with dementia. DATA SOURCES Combined Veterans Health Administration (VHA) and Medicare data in Fiscal Years (FYs) 2014-2015. STUDY DESIGN FY 2014 COC was measured by the Bice-Boxerman Continuity of Care (BBC) index on a 0-1 scale. FY 2015 total combined VHA and Medicare cost, institutional cost of acute inpatient, emergency department [ED], long-/short-stay nursing home, and noninstitutional long-term care (LTC) cost for medical (like skilled-) and social (like unskilled-) services were assessed controlling for covariates. An instrumental variable for COC (change of residence by more than 10 miles) was used to account for unobserved health confounders. DATA COLLECTION Community-dwelling veterans with dementia aged 66 and older, enrolled in Traditional Medicare (N = 102 073). PRINCIPAL FINDINGS Mean BBC in FY 2014 was 0.32; mean total cost in FY 2015 was $35 425. A 0.1 higher BBC resulted in (a) $4045 lower total cost; (b) $1597 lower acute inpatient cost, $119 lower ED cost, $4368 lower long-stay nursing home cost; (c) $402 higher noninstitutional medical LTC and $764 higher noninstitutional social LTC cost. BBC had no impact on short-stay nursing home cost. CONCLUSIONS COC is an effective approach to reducing total health care cost by supporting noninstitutional care and reducing institutional care.

Abstract
OBJECTIVES The main objective of this study was to estimate effects of dementia on Medicaid expenditures in an ethnically diverse community. METHODS The sample included 1,211 Medicare beneficiaries who did not have any Medicaid coverage and 568 who additionally had full Medicaid coverage enrolled in the Washington Heights-Inwood Columbia Aging Project (WHICAP), a multiethnic, population-based, prospective study of cognitive aging in northern Manhattan (1999-2010). Individuals' dementia status was determined using a rigorous clinical protocol. Relationship between dementia and Medicaid coverage and expenditures were estimated using a two-part model. RESULTS In participants who had full Medicaid coverage, average annual Medicaid expenditures were substantially higher for those with dementia than those without dementia ($50,270 vs. $21,966, p < .001), but Medicare expenditures did not differ by dementia status ($8,458 vs. $9,324, p = .19). In participants who did not have any Medicaid coverage, average annual Medicare expenditures were substantially higher for those with dementia than those without dementia ($12,408 vs. $8,113, p = .02). In adjusted models, dementia was associated with a $6,278 increase in annual Medicaid spending per person after controlling for other characteristics. DISCUSSION Results highlight Medicaid's contribution to covering the cost of dementia care in addition to Medicare. Studies that do not include Medicaid are unlikely to accurately reflect the true cost of dementia.

Abstract
INTRODUCTION Research has shown increased health-care resource use (HRU) among patients with Alzheimer's disease and related disorders (ADRD) well before diagnosis, but the degree to which HRU is correlated with disease severity at the time of initial assessment is not well documented. METHODS Retrospective analysis of linked medical records and claims data for three cohorts: mild ADRD (first [index] Mini-Mental State Examination [MMSE] ≥20), moderate/severe ADRD (index MMSE < 20), controls without cognitive impairment. HRU during the pre-index year was compared using multivariate regressions. RESULTS ADRD cohorts had significantly (P < .01) higher HRU than controls. Compared to mild ADRD patients, moderate/severe ADRD patients had higher rates of hospitalizations (relative risk [RR]: 1.57), emergency department visits (RR: 1.36), potentially avoidable hospitalizations (RR: 1.72), and accidental falls (RR: 1.58). DISCUSSION HRU before initial assessment increases with disease severity at the time of assessment, highlighting the need for timely evaluation and improved management in the earliest stages of ADRD.

[PMID: 31797361 DOI: 10.1111/jgs.16262] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2019] [Revised: 09/13/2019] [Accepted: 09/17/2019] [Indexed: 01/22/2023]
Abstract
OBJECTIVES Our aim was to describe the incidence of Alzheimer's disease (AD) in the United States, overall and by geographic region. DESIGN We conducted retrospective analyses of administrative claims data for a 5% random sample of US Medicare beneficiaries aged 65 years or older. AD incidence, defined as a diagnosis for AD (International Classification of Disease, Ninth Revision, Clinical Modification code 331.0×) in a given year, with no AD diagnosis in the beneficiary's entire medical history, was estimated for each calendar year between 2007 and 2014. Beneficiaries were required to be enrolled in Medicare for the calendar year of evaluation as well as the preceding 12 months. In addition, a cross-sectional assessment of geographic variation in AD incidence was conducted for 2014. For each population area (specifically, core-based statistical area, as defined by the US Census Bureau), AD incidence was estimated overall, as well as adjusted for differences in underlying patient demographics and metrics of access to care and quality of care. Changes in AD incidence from 2007 were also estimated. SETTING US fee-for-service Medicare. PARTICIPANTS US Medicare beneficiaries aged 65 years or older with no history of AD. RESULTS Overall, the diagnosed incidence of AD decreased over time, from 1.53% in 2007 to 1.09% in 2014; trends were similar for most population areas. In 2014, the rates of AD incidence ranged from 0% to more than 3% across population areas, with the highest observed incidence rates in areas of the Midwest and the South. Statistical models explain little of the geographic variation, although following adjustment, the incidence rates increased the most (in relative terms) in rural areas of western states. CONCLUSION Our findings are consistent with previously reported estimates of incidence of AD in the United States and its recent declining trend. Additionally, the study highlights the considerable geographic variation in the incidence of AD in the United States and suggests that further research is needed to better understand the determinants of this geographic variation.

Abstract
INTRODUCTION This study evaluates rates of all-cause emergency department visits, all-cause hospitalizations, potentially avoidable hospitalizations, and falls in 3 years preceding Alzheimer's disease (AD) diagnosis. METHODS Patients with AD and controls with no cognitive impairment were identified from the Medicare claims data. Patients were required to be aged ≥ 65 years and have continuous Medicare enrollment for ≥4 years before the index date (AD cohort: first AD diagnosis in 2012-2014; controls: randomly selected medical claim). Outcomes for each preindex year were compared among propensity score-matched cohorts. RESULTS Each year, before index, patients with AD were more likely to have all-cause emergency department visits, all-cause hospitalizations, potentially avoidable hospitalizations, and falls (P < .05 for all comparisons) than matched controls (N = 19,679 pairs). Increasing absolute and relative risks over time were observed for all outcomes. DISCUSSION The study findings highlight the growing burden of illness before AD diagnosis and emphasize the need for timely recognition and management of patients with AD.

Abstract
Importance As the life expectancy of people with Down syndrome (DS) has markedly increased over the past decades, older adults with DS may be experiencing a higher incidence of aging conditions. In addition to longevity, the amyloid precursor protein gene located on chromosome 21 places individuals with DS at a high risk for developing Alzheimer disease. Yet, few studies have determined prevalence of dementia and comorbidities among older people with DS. Objective To determine the prevalence of dementia and aging-related comorbidities in older adult individuals with DS. Design, Setting, and Participants Cross-sectional analysis of 2015 California Medicare claims data. We examined 1 year of cross-sectional Medicare claims data that included 100% of Californian Medicare beneficiaries enrolled in both Medicare Part A and B in 2015. Of these 3 001 977 Californian Medicare beneficiaries 45 years or older, 878 individuals were identified as having a diagnosis of DS. Data were analyzed between April 2017 and February 2018. Main Outcomes and Measures The frequency of DS dementia was assessed across different age categories. The number and frequency of 27 comorbidities were compared among individuals with DS with and without dementia and by age and sex groups. Results A total of 353 DS individuals (40%) were identified as having dementia diagnoses (mean, 58.7 years; 173 women [49%]) and 525 without dementia diagnoses (mean, 55.9 years; 250 women [48%]). The frequency of DS dementia among those 65 years or older rose to 49%. The mean number of comorbidities per individual increased with age in general. Comorbid conditions were more numerous among those with dementia compared with those with DS without dementia (mean, 3.4 vs 2.5, respectively), especially among those younger than 65 years. In particular, 4 treatable conditions, hypothyroidism, epilepsy, anemia, and weight loss, were much more frequent in DS dementia. Conclusions and Relevance Older Medicare beneficiaries in California with DS, especially those with dementia, have a high level of multimorbidity including several treatable conditions. While DS follow-up has long been confined to the pediatric sphere, we found that longevity in individuals with DS will necessitate complex adult and geriatric care. More evidenced-based and standardized follow-up could support better long-term comorbidity management and dementia care among aging adults with DS.

Abstract
OBJECTIVES We conducted a systematic review of studies reporting the direct healthcare costs of treating older adults with diagnosed Alzheimer disease and related dementias (ADRD) within private Medicare managed care plans. STUDY DESIGN A systematic review of all studies published in English reporting original empirical analyses of direct costs for older adults with ADRD in Medicare managed care. METHODS All papers indexed in PubMed or Web of Science reporting ADRD costs within Medicare managed care plans from 1983 through 2018 were identified and reviewed. RESULTS Despite the growth in Medicare managed care enrollment, only 9 papers report the costs of care for individuals with ADRD within these plans, and only 1 study reports data less than 10 years old. This limited literature reports wide ranges for ADRD-attributable costs, with estimates varying from $3738 to $8726 in annual prevalent costs and $8938 to $38,794 in 1-year immediate postdiagnosis incident costs. Reviewed studies also used varied study populations, case and cost ascertainment methods, and analytic methods, making cross-study comparisons difficult. CONCLUSIONS The expected continued growth in Medicare managed care enrollment, coupled with the large and growing impact of ADRD on America's healthcare delivery and finance systems, requires more research on the cost of ADRD within managed care. This research should use more consistent approaches to identify ADRD prevalence and provide more detail regarding which components of care are included in analyses and how the costs of care are captured and measured.

Abstract
Background: Persons with advanced dementia cannot initiate activities because of the executive dysfunction. The lack of activities was identified as one of the most important factors contributing to behavioral problems of these persons. The unmet needs were boredom/sensory deprivation, loneliness/need for social interaction, and need for meaningful activities. There is a need for activities designed specifically for residents with advanced dementia. Objective: A description of patient’s needs and of programs that intend to maintain quality of life for people with dementia and facing death. Data sources: A literature review of programs used for persons with advanced dementia and residing in long-term facilities, using the PubMed data base and collateral sources. Results: Since palliative care is appropriate for persons with advanced dementia, attention has to be paid to three following important aspects of care: Medical issues, behavioral symptoms, and meaningful activities. Medical interventions should be limited to those which have more benefits than burdens, behavioral symptoms should be distinguished according to the context in which they occur, and treated by non-pharmacological interventions that involve meaningful activities. This review describes four programs that may promote the quality of life in persons with advanced dementia and facing death. They are designed for persons with advanced dementia, taking into account their functional impairments. Most of these programs involve short infrequent sessions. In contrast, Namaste Care is a daily extended program of enhanced nursing care that can provide quality of life until the last breath. Conclusions: It is possible to maintain quality life for people with advanced dementia if a special program of activities is available.

Abstract
BACKGROUND People with dementia (PwD) suffer from coexisting medical conditions, creating complex clinical challenges and increasing the risk of poor outcomes, which could be associated with high healthcare cost. OBJECTIVE To describe the prevalence of comorbidity in PwD and to analyze the association between comorbidity in dementia diseases and healthcare costs from a payer's perspective. METHODS This cross-sectional analysis was based on n = 362 PwD of the DelpHi-MV trial (Dementia: Life-and person-centered help in Mecklenburg-Western Pomerania). Comorbidity was assessed using the Charlson comorbidity index (CCI) and was categorized into low, high, and very high comorbidity. Healthcare resource utilization and unit costs were used to calculate costs. Multivariable regression models were applied to analyze the association between comorbidity and costs. RESULTS Comorbidity was highly prevalent in the sample. 47% of PwD had a very high, 37% a high, and 16% a low comorbidity in addition to dementia. The most prevalent co-existing comorbidity were diabetes mellitus (42%), peripheral vascular disease (28%) and cerebrovascular disease (25%). Total costs significantly increased by 528€ (SE = 214, CI95 = 109-947, p = 0.014) with each further comorbidity, especially due to higher cost for medication and medical aids. Compared with a low comorbidity, a very high comorbidity was significantly associated with 818€ (SE = 168, CI95 = 489-1147, p < 0.001) higher medication costs and 336€ (SE = 161, CI95 = 20-652, p = 0.037) higher cost for medical aids. There were no significant association between a higher comorbidity and cost for formal care services. CONCLUSIONS Comorbidity in PwD represents a substantial financial burden on healthcare payers and is a challenge for patients, healthcare providers, and the health systems. Innovative approaches are needed to achieve a patient-oriented management of treatment and care in comorbid PwD to reduce long-term costs.

Abstract
BACKGROUND Prior studies have suggested that dementia adversely influences clinical outcomes and increases resource utilization in patients hospitalized for acute diseases. However, there is limited population-data information on the impact of dementia among elderly hospitalized patients with sepsis. METHODS From the 2009-2011 National Hospital Discharge Database we identified hospitalizations in adults aged ≥65 years. Using ICD9-CM codes, we selected sepsis cases, divided them into two cohorts (with and without dementia) and compared both groups with respect to organ dysfunction, in-hospital mortality and the use of hospital resources. We estimated the impact of dementia on these primary endpoints through multivariate regression models. RESULTS Of the 148 293 episodes of sepsis identified, 16 829 (11.3%) had diagnoses of dementia. Compared to their dementia-free counterparts, they were more predominantly female and older, had a lower burden of comorbidities and were more frequently admitted due to a principal diagnosis of sepsis. The dementia cohort showed a lower risk of organ dysfunction (adjusted OR: 0.84, 95% Confidence Interval [CI]: 0.81, 0.87) but higher in-hospital mortality (adjusted OR: 1.32, 95% [CI]: 1.27, 1.37). The impact of dementia on mortality was higher in the cases of younger age, without comorbidities and without organ dysfunction. The cases with dementia also had a lower length of stay (-3.87 days, 95% [CI]: -4.21, -3.54) and lower mean hospital costs (-3040€, 95% [CI]: -3279, -2800). CONCLUSIONS This nationwide population-based study shows that dementia is present in a substantial proportion of adults ≥65s hospitalized with sepsis, and while the condition does seem to come with a lower risk of organ dysfunction, it exerts a negative influence on in-hospital mortality and acts as an independent mortality predictor. Furthermore, it is significantly associated with shorter length of stay and lower hospital costs.

Abstract
PURPOSE Identification of Alzheimer disease and related dementias (ADRD) subtypes is important for pharmacologic treatment and care planning, yet inaccuracies in dementia diagnoses make ADRD subtypes hard to identify and characterize. The objectives of this study were to (1) develop a method to categorize ADRD cases by subtype and (2) characterize and compare the ADRD subtype populations by demographic and other characteristics. METHODS We identified cases of ADRD occurring during 2008 to 2014 from the OptumLabs Database using diagnosis codes and antidementia medication fills. We developed a categorization algorithm that made use of temporal sequencing of diagnoses and provider type. RESULTS We identified 36,838 individuals with ADRD. After application of our algorithm, the largest proportion of cases were nonspecific dementia (41.2%), followed by individuals with antidementia medication but no ADRD diagnosis (15.6%). Individuals with Alzheimer disease formed 10.2% of cases. Individuals with vascular dementia had the greatest burden of comorbid disease. Initial documentation of dementia occurred primarily in the office setting (35.1%). DISCUSSION Our algorithm identified 6 dementia subtypes and three additional categories representing unique diagnostic patterns in the data. Differences and similarities between groups provided support for the approach and offered unique insight into ADRD subtype characteristics.

Abstract
BACKGROUND Predictive models for earlier diagnosis of Alzheimer's disease and related dementias (ADRD) that rely on variables requiring assessment during an office visit, such as cognitive function, body mass index, or lifestyle factors, may not be broadly applicable, since that level of data may be inaccessible or inefficient. OBJECTIVE To build a predictive model for earlier diagnosis of ADRD using only administrative claims data to enhance applicability at the health care-system level. Building on the strength of this approach and knowledge that health care utilization (HCU) is increased before dementia diagnosis, it was hypothesized that previous HCU history would improve predictive ability of the model. METHODS We conducted a case-control study using data from the OptumLabs Data Warehouse. ADRD was defined using ICD-9-CM codes and prescription fills for antidementia medications. We included individuals with mild cognitive impairment. Cases aged ≥ 18 years with a diagnosis between 2011-2014 were matched to controls without ADRD. HCU variables were incorporated into regression models along with comorbidities and symptoms. RESULTS The derivation cohort comprised 24,521 cases and 95,464 controls. Final adjusted models were stratified by age. We obtained moderate accuracy (c-statistic = 0.76) for the model among younger (aged < 65 years) adults and poor discriminatory ability (c-statistic = 0.63) for the model among older adults (aged ≥ 65 years). Neurological and psychological disorders had the largest effect estimates. CONCLUSIONS We created age-stratified predictive models for earlier diagnosis of dementia using information available in administrative claims. These models could be used in decision support systems to promote targeted cognitive screening and earlier dementia recognition for individuals aged < 65 years. These models should be validated in other cohorts. DISCLOSURES This research was supported by AstraZeneca, Global CEO Initiative, Janssen, OptumLabs, and Roche.

Abstract
INTRODUCTION Prior studies have reported higher health care utilization (HCU) leading up to diagnosis of the Alzheimer disease and related dementia (ADRD), but none have assessed variation in HCU by ADRD subtype or examined disease-specific HCU. The objectives of this study were to identify ADRD subtypes and: (1) characterize all-cause and (2) disease-specific HCU during the 3 years preceding diagnosis, and (3) determine if HCU varied by ADRD subtype. METHODS We used data from the OptumLabs Data Warehouse 2008 to 2014 to identify ADRD subtypes (total N=36,838) using an algorithm based on temporal sequencing of diagnoses and provider type. Annual counts of all-cause and disease-specific HCU in each of the 3 years preceding ADRD diagnosis were regressed on ADRD subtypes with mild cognitive impairment (MCI) as the reference group, year, and other variables. RESULTS HCU increased over time, was highest in the outpatient setting, and varied by ADRD subtype. Compared with MCI, highest HCU was observed in vascular and nonspecific dementia. Compared with MCI, most subtypes had elevated disease-specific HCU. DISCUSSION Variation in HCU by ADRD subtype points to different pathways to diagnosis and patterns of use.

Abstract
BACKGROUND Multimorbidity in dementia is associated with an increased risk of complications and a higher need for care. Having knowledge of cardiovascular and metabolic comorbidities is crucial when making decisions about diagnostic procedures and therapies. We compared the prevalence of comorbidities in hospitalized patients with Alzheimer's disease (AD), vascular dementia, and psychiatric diseases other than dementia. Additionally, we compared clinically relevant health-care indicators (length of hospital stay, rate of re-hospitalization) between these groups. METHODS We used information from a database of treatment-relevant indicators from psychiatric and psychosomatic hospitals throughout Germany. This database contains routinely recorded data collected from 85 German hospitals from 2011 to 2015. In total, 14 411 AD cases, 7156 vascular dementia cases, and 34 534 cases involving non-demented psychiatric patients (used as controls) were included. To analyze comorbidities and health-care indicators, χ2 tests and t-tests were used. RESULTS Diabetes mellitus, lipoprotein disorders, coronary artery diseases, cardiac arrhythmia and insufficiency, and atherosclerosis were significantly more prevalent in patients with vascular dementia than in those with AD and psychiatric controls. Hypertension and coronary artery diseases were less frequently associated with AD than with non-demented psychiatric controls (P < 0.001). Additionally, dementia patients with cardiovascular or metabolic diseases exhibited longer hospital stays (+ 1.4 days, P < 0.001) and were more often re-hospitalized within 3 weeks (P < 0.001) and 1 year (P < 0.001) compared to dementia patients without these comorbidities. CONCLUSIONS Awareness of somatic comorbidities in patients with dementia is crucial to avoid complications during inpatient treatment. The occurrence of comorbid disorders was associated with longer and more frequent hospital stays, which potentially lead to higher health-care costs. Further studies should evaluate the causative association between somatic comorbidities and inpatient costs in dementia patients.

Abstract
BACKGROUND Current information is scarce regarding comorbid conditions, treatment, survival, institutionalization, and health care utilization for Alzheimer's disease (AD) patients. OBJECTIVES Compare all-cause mortality, rate of institutionalization, and economic burden between treated and untreated newly-diagnosed AD patients. METHODS Patients aged 65-100 years with ≥1 primary or ≥2 secondary AD diagnoses (ICD-9-CM:331.0] with continuous medical and pharmacy benefits for ≥12 months pre-index and ≥6 months post-index date (first AD diagnosis date) were identified from Medicare fee-for-service claims 01JAN2011-30JUN2014. Patients with AD treatment claims or AD/AD-related dementia diagnosis during the pre-index period were excluded. Patients were assigned to treated and untreated cohorts based on AD treatment received post-index date. Total 8,995 newly-diagnosed AD patients were identified; 4,037 (44.8%) were assigned to the treated cohort. Time-to-death and institutionalization were assessed using Cox regression. To compare health care costs and utilizations, 1 : 1 propensity score matching (PSM) was used. RESULTS Untreated patients were older (83.85 versus 81.44 years; p < 0.0001), with more severe comorbidities (mean Charlson comorbidity index: 3.54 versus 3.22; p < 0.0001). After covariate adjustment, treated patients were less likely to die (hazard ratio[HR] = 0.69; p < 0.0001) and were associated with 20% lower risk of institutionalization (HR = 0.801; p = 0.0003). After PSM, treated AD patients were less likely to have hospice visits (3.25% versus 9.45%; p < 0.0001), and incurred lower annual all-cause costs ($25,828 versus $30,110; p = 0.0162). CONCLUSION After controlling for comorbidities, treated AD patients have better survival, lower institutionalization, and sometimes fewer resource utilizations, suggesting that treatment and improved care management could be beneficial for newly-diagnosed AD patients from economic and clinical perspectives.

Abstract
Introduction:
In a recent report, the American Heart Association estimated that medical costs and productivity losses of cardiovascular disease (CVD) are expected to grow from $555 billion in 2015 to $1.1 trillion in 2035. Although the burden is significant, the estimate does not include the costs of family, informal, or unpaid caregiving provided to patients with CVD. In this analysis, we estimated projections of costs of informal caregiving attributable to CVD for 2015 to 2035.
Methods:
We used data from the 2014 Health and Retirement Survey to estimate hours of informal caregiving for individuals with CVD by age/sex/race using a zero-inflated binomial model and controlling for sociodemographic factors and health conditions. Costs of informal caregiving were estimated separately for hypertension, coronary heart disease, heart failure, stroke, and other heart disease. We analyzed data from a nationally representative sample of 16 731 noninstitutionalized adults ≥54 years of age. The value of caregiving hours was monetized by the use of home health aide workers’ wages. The per-person costs were multiplied by census population counts to estimate nation-level costs and to be consistent with other American Heart Association analyses of burden of CVD, and the costs were projected from 2015 through 2035, assuming that within each age/sex/racial group, CVD prevalence and caregiving hours remain constant.
Results:
The costs of informal caregiving for patients with CVD were estimated to be $61 billion in 2015 and are projected to increase to $128 billion in 2035. Costs of informal caregiving of patients with stroke constitute more than half of the total costs of CVD informal caregiving ($31 billion in 2015 and $66 billion in 2035). By age, costs are the highest among those 65 to 79 years of age in 2015 but are expected to be surpassed by costs among those ≥80 years of age by 2035. Costs of informal caregiving for patients with CVD represent an additional 11% of medical and productivity costs attributable to CVD.
Conclusions:
The burden of informal caregiving for patients with CVD is significant; accounting for these costs increases total CVD costs to $616 billion in 2015 and $1.2 trillion in 2035. These estimates have important research and policy implications, and they may be used to guide policy development to reduce the burden of CVD on patients and their caregivers.

Abstract
BACKGROUND Few studies have examined how dementia and comorbidities may interact to affect healthcare expenditures. OBJECTIVE To examine whether effects of dementia severity on Medicare expenditures differed for individuals with different levels of comorbidities. METHODS Data are drawn from the Washington Heights-Inwood Columbia Aging Project (WHICAP). Comprehensive clinical assessments of dementia severity were systematically carried out at ∼18 month intervals. Dementia severity was measured by Clinical Dementia Rating (CDR). Comorbidities were measured by a modified Elixhauser comorbidities index. Generalized linear models examined effects of dementia severity, comorbidities, and their interactions on Medicare expenditures (1999-2010). RESULTS At baseline, 1,280 subjects were dementia free (CDR = 0, 66.4%), 490 had very mild dementia (CDR = 0.5, 25.4%), 108 had mild dementia (CDR = 1, 5.6%), and 49 had moderate/severe dementia (CDR = 2/3, 2.5%). Average annual Medicare expenditures for individuals with moderate/severe dementia were more than twice as high as those who were dementia free (CDR = 0: $9,108, CDR = 0.5/1: $11,664, CDR≥2: $19,604, p < 0.01). Expenditures were approximately 10 times higher among those with≥3 comorbidities than among those with no comorbidities ($2,612 for those with no comorbidities, to $6,109 for those with 1, $10,656 for those with 2, and $30,244 for those with≥3 comorbidities, p < 0.001). Dementia severity was associated with higher expenditures, but comorbidities were the most important predictor of expenditures. We did not find strong interaction effects between number of comorbidities and dementia severity. CONCLUSIONS Increasing dementia severity and higher comorbidities are associated with higher Medicare expenditures. Care of individuals with dementia should focus on management of comorbidities.

Abstract
Background dementia is increasingly recognised as life-limiting condition. Although the benefits of acetylcholinesterase inhibitors (AChEIs) on cognition and function are well established, their effect on survival is less clear. Objective to investigate associations between AChEI prescription and mortality in patients with Alzheimer's dementia (AD) in a naturalistic setting, using detailed baseline data on cognition, functioning, and mental and physical wellbeing. Methods we used a large mental healthcare database in South London, linked to Hospital Episode Statistics and Office for National Statistics mortality data, to assemble a retrospective cohort. We conducted a survival analysis adjusting for a wide range of potential confounders using propensity scores to reduce the impact of confounding by indication. Results of 2,464 patients with AD, 1,261 were prescribed AChEIs. We detected a strong association between AChEI receipt and lower mortality (hazard ratio = 0.57; 95% CI 0.51-0.64). This remained significant after controlling for a broad range of potential confounders including psychotropic co-prescription, symptom severity, functional status and hospital admissions (hazard ratio = 0.77; 95% CI 0.67-0.87). Conclusions in a large cohort of patients with AD, AChEI prescription was associated with reduced risk of death by more than 20% in adjusted models. This has implications for individual care planning and service development.

Abstract
INTRODUCTION Clinical features of dementia (cognition, function, and behavioral and psychological symptoms) may differentially affect out-of-pocket medical and nursing home (NH) expenditures and informal care received (outcomes). METHODS We used cross-sectional data (Aging, Demographics, and Memory Study) to estimate probabilities of experiencing outcomes by clinical features. For those experiencing an outcome, we estimated effects of clinical features on the amount of the outcome. RESULTS No clinical feature predicted the probability of having out-of-pocket medical expenditures. For those with medical expenditures, higher cognition and poorer function were associated with more spending. Poorer function predicted having out-of-pocket NH expenditures. For those with NH expenditures, no clinical feature predicted the amount. Poorer function and a greater number of behavioral and psychological symptoms predicted the probability of receiving caregiving. For those receiving care, poorer function was associated with more caregiving. CONCLUSIONS Clinical features differentially impact outcomes with poorer function associated with all types of costs and caregiving received.

Abstract
As life expectancy increases so people often develop a range of conditions and disabilities in the years before death. Multimorbidity represents the most common 'disease pattern' found among the elderly and is characterised by complex interactions of co-existing diseases where a medical approach focused on a single disease does not suffice. People with dementia who also have other comorbidities do not always have their comorbid conditions managed as those without dementia which often lead to a high number of hospital admissions with longer lengths of stay and greater treatment costs. This case study presents the case management approach taken by Admiral Nursing in managing the complexities where there is comorbidity of a long-term condition and a diagnosis of dementia. By empowering the person and their carer with information and choices and through good case management and communication, people can be supported to live well and avoid inappropriate hospital admissions.

Abstract
The level of assistance patients with Alzheimer disease (AD) require in their care may be an important predictor of resource use, costs of care, and quality of life. The Dependence Scale (DS), a measure of care-assistance required, was used to estimate costs of care and quality of life of patients with AD categorized into 6 dependence stages based upon the summated item scores of the DS. Data were derived from a 3-year, noninterventional study of 132 patients with probable AD (ages, 50 to 85 y) and caregiver dyads. We investigated the association between DS scores and health care costs, health-related quality of life (HRQoL), caregiver burden and estimated annual costs and HRQoL for 6 dependence stages in adjusted models. DS scores were significant predictors of health care costs, HRQoL, and caregiver burden. The estimated annual health care costs and a measure of HRQoL (EuroQoL-5D) ranged from $11,418 and 1.00 for those at very mild dependence stage to $101,715 and 0.26 for those at very severe dependence stage. DS scores classified into 6 dependence stages provides a useful method to estimate unique levels of care-associated costs and health utilities for pharmacoeconomic evaluations of new treatments for AD.

Abstract
OBJECTIVE The challenges posed by people living with multiple chronic conditions are unique for people with dementia and other significant cognitive impairment. There have been recent calls to action to review the existing literature on co-occurring chronic conditions and dementia in order to better understand the effect of cognitive impairment on disease management, mobility, and mortality. METHODS This systematic literature review searched PubMed databases through 2011 (updated in 2016) using key constructs of older adults, moderate-to-severe cognitive impairment (both diagnosed and undiagnosed dementia), and chronic conditions. Reviewers assessed papers for eligibility and extracted key data from each included manuscript. An independent expert panel rated the strength and quality of evidence and prioritized gaps for future study. RESULTS Four thousand thirty-three articles were identified, of which 147 met criteria for review. We found that moderate-to-severe cognitive impairment increased risks of mortality, was associated with prolonged institutional stays, and decreased function in persons with multiple chronic conditions. There was no relationship between significant cognitive impairment and use of cardiovascular or hypertensive medications for persons with these comorbidities. Prioritized areas for future research include hospitalizations, disease-specific outcomes, diabetes, chronic pain, cardiovascular disease, depression, falls, stroke, and multiple chronic conditions. CONCLUSIONS This review summarizes that living with significant cognitive impairment or dementia negatively impacts mortality, institutionalization, and functional outcomes for people living with multiple chronic conditions. Our findings suggest that chronic-disease management interventions will need to address co-occurring cognitive impairment. Copyright © 2017 John Wiley & Sons, Ltd.

Abstract
OBJECTIVES The optimal care of people with dementia in general hospitals has become a policy and practice imperative over recent years. However, despite this emphasis, the everyday experience of staff caring for this patient group is poorly understood. This review aimed to synthesise the findings from recent qualitative studies in this topic published prior to January 2014 to develop knowledge and provide a framework to help inform future training needs. METHOD A systematic search of the literature was conducted across five academic databases and inclusion/exclusion criteria applied to the retrieved papers. A meta-ethnographic approach was utilised to synthesise the resulting 14 qualitative papers. RESULTS Five key themes were constructed from the findings: overcoming uncertainty in care; constraints of the environmental and wider organisational context; inequality of care; recognising the benefits of person-centred care; and identifying the need for training. These themes explore the opportunities and challenges associated with caring for this group of patients, as well as suggestions to improve staff experiences and patient care. CONCLUSION The synthesis highlighted a lack of knowledge and understanding of dementia within general hospital staff, particularly with regard to communication with patients and managing behaviours that are considered challenging. This limited understanding, coupled with organisational constraints on a busy hospital ward, contributed to low staff confidence, negative attitudes towards patients with dementia and an inability to provide person-centred care. The benefits of dementia training for both ward staff and hospital management and peer discussion/support for ward staff are discussed.

Abstract
Objective: To estimate the cost of dementia care and its relation to dependence. Method: Disease severity and health care resource utilization was retrieved from the Swedish National Study on Aging and Care. Informal care was assessed with the Resource Utilization in Dementia instrument. A path model investigates the relationship between annual cost of care and dependence, cognitive ability, functioning, neuropsychiatric symptoms, and comorbidities. Results: Average annual cost among patients diagnosed with dementia was €43,259, primarily incurred by accommodation. Resource use, that is, institutional care, community care, and accommodation, and corresponding costs increased significantly by increasing dependency. Path analysis showed that cognitive ability, functioning, and neuropsychiatric symptoms were significantly correlated with dependence, which in turn had a strong impact on annual cost. Discussion: This study confirms that cost of dementia care increases with dependence and that the impact of other disease indicators is mainly mediated by dependence.

Abstract
INTRODUCTION Identifying factors associated with lower dementia care costs is essential. We examined whether two caregiver factors were associated with lower costs of informal care. METHODS A total of 271 care dyads of the Cache County Dementia Study were included. Estimates of informal costs were based on caregiver reports of time spent in care-related activities and inflation-adjusted 2012 Utah median hourly wages. Caregiver coping and emotional closeness with the care-recipient were assessed using the Ways of Coping Checklist-Revised and Relationship Closeness Scale, respectively. RESULTS Higher closeness was associated with 24% lower costs (expβ = 0.763 [95% confidence interval: 0.583-0.999]) in linear mixed models controlling for demographics and baseline dementia severity and duration. Problem-focused coping was not associated with informal costs (P = .354). DISCUSSION Caregiver closeness, a potentially modifiable factor, predicted lower dementia informal care costs over time. Future studies examining the care environment in closer dyads may identify specific care-related behaviors or strategies that are associated with lower costs.

Abstract
BACKGROUND Alzheimer's disease (AD) is associated with considerable costs and has a significant impact on health and social care systems. OBJECTIVE This study assessed whether baseline comorbidities present in 2,594 patients with AD participating in two semagacestat randomized placebo-controlled trials (RCTs) would significantly impact overall costs. METHODS Resource utilization was captured using the Resource Utilization in Dementia Scale-Lite. Comorbidities and concomitant medications were tabulated via patient and caregiver reports. Only baseline data were analyzed. Direct and indirect costs per month were calculated per patient. The relationship between cost and explanatory variables was explored in a regression model. RESULTS The baseline monthly cost of care in this RCT population was £1,147 ± 2,483, with informal care costs accounting for 75% of costs. Gender, age, and functional status were significant predictors of costs (p ≤ 0.0001). The cost ratio was not impacted when the number of comorbidities was added to the model (cost ratio = 0.95; 95% CI 0.91-0.99) or when combined with the number of concomitant medications (cost ratio = 0.97; 95% CI 0.95-1.00). Inconsistent findings related to the impact of individual comorbidities on costs were noted in sensitivity analyses. CONCLUSIONS The number of comorbidities, alone or when combined with concomitant medications, did not impact baseline costs of care, perhaps because RCTs often enroll less severely ill and more medically stable patients. However, higher costs were consistently associated with greater functional impairment similar to non-RCT databases. Supplemental sources (e.g., claims databases) are likely needed to better estimate the effects of disease and treatment on costs of illness captured in RCTs for AD.
