Cost-Effective Care Coordination for People With Dementia at Home.

BACKGROUND AND OBJECTIVES: People with dementia (PWD) represent some of the highest-need and highest-cost individuals living in the community. Maximizing Independence (MIND) at Home is a potentially cost-effective and scalable home-based dementia care coordination program that uses trained, nonclinical community workers as the primary contact between the PWD and their care partner, supported by a multidisciplinary clinical team with expertise in dementia care. RESEARCH DESIGN AND METHODS: Cost of care management services based on actual time spent by care management personnel over first 12 months of MIND at Home intervention was calculated for 342 MIND at Home recipients from Baltimore, Maryland and surrounding areas participating in a Centers for Medicare and Medicaid Services (CMS) funded Health Care Innovation Award demonstration project. Difference-in-differences analysis of claims-based Medicaid spending of 120 dually-eligible MIND at Home participants with their propensity score matched comparison group (n = 360). RESULTS: The average cost per enrollee per month was $110, or $1,320 per annum. Medicaid expenditures of dually-eligible participants grew 1.12 percentage points per quarter more slowly than that of the matched comparison group. Most savings came from slower growth in inpatient and long-term nursing home use. Net of the cost of the 5-year MIND at Home intervention, 5-year Medicaid savings are estimated at $7,052 per beneficiary, a 1.12-fold return on investment. DISCUSSION AND IMPLICATIONS: Managed care plans with the flexibility to engage community health workers could benefit from a low-cost, high-touch intervention to meet the needs of enrollees with dementia. Limitations for using and reimbursing community health workers exist in Medicare fee-for-service, which CMS should address to maximize benefit for PWD.

Attitudes toward advance care planning among persons with dementia and their caregivers.

OBJECTIVES: To examine factors that influence decision-making, preferences, and plans related to advance care planning (ACP) and end-of-life care among persons with dementia and their caregivers, and examine how these may differ by race. DESIGN: Cross-sectional survey. SETTING: 13 geographically dispersed Alzheimer's Disease Centers across the United States. PARTICIPANTS: 431 racially diverse caregivers of persons with dementia. MEASUREMENTS: Survey on "Care Planning for Individuals with Dementia." RESULTS: The respondents were knowledgeable about dementia and hospice care, indicated the person with dementia would want comfort care at the end stage of illness, and reported high levels of both legal ACP (e.g., living will; 87%) and informal ACP discussions (79%) for the person with dementia. However, notable racial differences were present. Relative to white persons with dementia, African American persons with dementia were reported to have a lower preference for comfort care (81% vs. 58%) and lower rates of completion of legal ACP (89% vs. 73%). Racial differences in ACP and care preferences were also reflected in geographic differences. Additionally, African American study partners had a lower level of knowledge about dementia and reported a greater influence of religious/spiritual beliefs on the desired types of medical treatments. Notably, all respondents indicated that more information about the stages of dementia and end-of-life health care options would be helpful. CONCLUSIONS: Educational programs may be useful in reducing racial differences in attitudes towards ACP. These programs could focus on the clinical course of dementia and issues related to end-of-life care, including the importance of ACP.

Unmet needs in community-living persons with dementia are common, often non-medical and related to patient and caregiver characteristics.

OBJECTIVE: Understanding which characteristics of persons with dementia (PWD) and their caregivers are associated with unmet needs can inform strategies to address those needs. Our purpose was to determine the percentage of PWD having unmet needs and significant correlates of unmet needs in PWD. DESIGN: Cross-sectional data were analyzed using bivariate and hierarchical multiple linear regression analyses. SETTING: Participants lived in the greater Baltimore, Maryland and Washington DC suburban area. PARTICIPANTS: A sample of 646 community-living PWD and their informal caregivers participated in an in-home assessment of dementia-related needs. MEASUREMENTS: Unmet needs were identified using the Johns Hopkins Dementia Care Needs Assessment. Correlates of unmet needs were determined using demographic, socioeconomic, clinical, functional and quality of life characteristics of the PWD and their caregivers. RESULTS: PWD had a mean of 10.6 (±4.8) unmet needs out of 43 items (24.8%). Unmet needs were most common in Home/Personal Safety (97.4%), General Health Care (83.1%), and Daily Activities (73.2%) domains. Higher unmet needs were significantly related to non-white race, lower education, higher cognitive function, more neuropsychiatric symptoms, lower quality of life in PWD, and having caregivers with lower education or who spent fewer hours/week with the PWD. CONCLUSIONS: Unmet needs are common in community-living PWD, and most are non-medical. Home-based dementia care can identify and address PWD's unmet needs by focusing on care recipients and caregivers to enable PWD to remain safely at home.

MIND at Home-Streamlined: Study protocol for a randomized trial of home-based care coordination for persons with dementia and their caregivers.

BACKGROUND: Dementia is associated with high health care costs, premature long-term care (LTC) placement, medical complications, reduced quality of life, and caregiver burden. Most health care providers and systems are not yet organized or equipped to provide comprehensive long-term care management for dementia, although a range of effective symptoms and supportive care approaches exist. The Maximizing Independence at Home-Streamlined (MIND-S) is a promising model of home-based dementia care coordination designed to efficiently improve person-centered outcomes, while reducing care costs. This report describes the rationale and design of an NIA-funded randomized controlled trial to test the impact of MIND-S on time to LTC placement, person with dementia outcomes (unmet needs, behavior, quality of life), family caregiver outcomes (unmet needs, burden), and cost offset at 18 (primary end point) and 24 months, compared to an augmented usual care group. METHODS: This is a 24-month, parallel group, randomized trial evaluating MIND-S in a cohort of 304 community-living persons with dementia and their family caregivers in Maryland. MIND-S dyads receive 18 months of care coordination by an interdisciplinary team comprised of trained non-clinical community workers (e.g. Memory Care Coordinators), a registered nurse, and a geriatric psychiatrist. Intervention components include in-home dementia-related needs assessments; individualized care planning; implementation of standardized evidence-based care strategy protocols; and ongoing monitoring and reassessment. Outcomes are assessed by blinded evaluators at baseline, 4.5, 9, 13.5, 18, and 24 months. DISCUSSION: Trial results will provide rigorous data to inform innovations in effective system-level approaches to dementia care.

Home is where the future is: The BrightFocus Foundation consensus panel on dementia care.

INTRODUCTION: A national consensus panel was convened to develop recommendations on future directions for home-based dementia care (HBDC). METHODS: The panel summarized advantages and challenges of shifting to HBDC as the nexus of care and developed consensus-based recommendations. RESULTS: The panel developed five core recommendations: (1) HBDC should be considered the nexus of new dementia models, from diagnosis to end of life in dementia; (2) new payment models are needed to support HBDC and reward integration of care; (3) a diverse new workforce that spans the care continuum should be prepared urgently; (4) new technologies to promote communication, monitoring/safety, and symptoms management must be tested, integrated, and deployed; and (5) targeted dissemination efforts for HBDC must be employed. DISCUSSION: HBDC represents a promising paradigm shift to improve care for those living with dementia and their family caregivers: these recommendations provide a framework to chart a course forward for HBDC.

Health Services Utilization in Older Adults with Dementia Receiving Care Coordination: The MIND at Home Trial.

OBJECTIVE: To investigate effects of a novel dementia care coordination program on health services utilization. DATA SOURCES/STUDY SETTING: A total of 303 community-dwelling adults aged ≥70 with a cognitive disorder in Baltimore, Maryland (2008-2011). STUDY DESIGN: Single-blind RCT evaluating efficacy of an 18-month care coordination intervention delivered through community-based nonclinical care coordinators, supported by an interdisciplinary clinical team. DATA COLLECTION/EXTRACTION METHODS: Study partners reported acute care/inpatient, outpatient, and home- and community-based service utilization at baseline, 9, and 18 months. PRINCIPAL FINDINGS: From baseline to 18 months, there were no significant group differences in acute care/inpatient or total outpatient services use, although intervention participants had significantly increased outpatient dementia/mental health visits from 9 to 18 months (p = .04) relative to controls. Home and community-based support service use significantly increased from baseline to 18 months in the intervention compared to control (p = .005). CONCLUSIONS: While this dementia care coordination program did not impact acute care/inpatient services utilization, it increased use of dementia-related outpatient medical care and nonmedical supportive community services, a combination that may have helped participants remain at home longer. Future care model modifications that emphasize delirium, falls prevention, and behavior management may be needed to influence inpatient service use.

Comprehensive home-based care coordination for vulnerable elders with dementia: Maximizing Independence at Home-Plus-Study protocol.

INTRODUCTION: Despite availability of effective care strategies for dementia, most health care systems are not yet organized or equipped to provide comprehensive family-centered dementia care management. Maximizing Independence at Home-Plus is a promising new model of dementia care coordination being tested in the U.S. through a Health Care Innovation Award funded by the Centers for Medicare and Medicaid Services that may serve as a model to address these delivery gaps, improve outcomes, and lower costs. This report provides an overview of the Health Care Innovation Award aims, study design, and methodology. METHODS: This is a prospective, quasi-experimental intervention study of 342 community-living Medicare-Medicaid dual eligibles and Medicare-only beneficiaries with dementia in Maryland. Primary analyses will assess the impact of Maximizing Independence at Home-Plus on risk of nursing home long-term care placement, hospitalization, and health care expenditures (Medicare, Medicaid) at 12, 18 (primary end point), and 24 months, compared to a propensity-matched comparison group. DISCUSSION: The goals of the Maximizing Independence at Home-Plus model are to improve care coordination, ability to remain at home, and life quality for participants and caregivers, while reducing total costs of care for this vulnerable population. This Health Care Innovation Award project will provide timely information on the impact of Maximizing Independence at Home-Plus care coordination model on a variety of outcomes including effects on Medicaid and Medicare expenditures and service utilization. Participant characteristic data, cost savings, and program delivery costs will be analyzed to develop a risk-adjusted payment model to encourage sustainability and facilitate spread.

Study partners perform essential tasks in dementia research and can experience burdens and benefits in this role.

Most studies that enroll individuals with dementia require a study partner for each participant. Study partners-usually family members-perform several key roles: accompanying the participant to visits, providing information about the participant, and assisting with procedures such as taking medication. Little is known, however, about their experiences when performing these roles. Dementia researchers and institutional review boards need to know these experiences because the study partner role is one key factor in a study's success. This prospective qualitative study, using up to three semi-structured interviews with 62 study partners involved in a range of dementia studies, documented their subjective experiences. Content analysis demonstrates that study partners perform a range of tasks-often within the context of being a caregiver-that enable cognitively impaired individuals to participate in dementia research. These tasks present study partners with unique burdens and benefits, some of which dementia researchers and institutional review boards can address.

A Multipronged, Adaptive Approach for the Recruitment of Diverse Community-Residing Elders with Memory Impairment: The MIND at Home Experience.

OBJECTIVE: To provide a critical review of a multipronged recruitment approach used to identify, recruit, and enroll a diverse community-based sample of persons with memory disorders into an 18-month randomized, controlled dementia care coordination trial. METHODS: Descriptive analysis of a recruitment approach comprised five strategies: community liaison ("gatekeepers") method, letters sent from trusted community organizations, display and distribution of study materials in the community, research registries, and general community outreach and engagement activities. Participants were 55 community organizations and 63 staff of community organizations in Baltimore, Maryland. Participant referral sources, eligibility, enrollment status, demographics, and loss to follow-up were tracked in a relational access database. RESULTS: In total, 1,275 referrals were received and 303 socioeconomically, cognitively, and racially diverse community-dwelling persons with cognitive disorders were enrolled. Most referrals came from letters sent from community organizations directly to clients on the study's behalf (39%) and referrals from community liaison organizations (29%). African American/black enrollees were most likely to come from community liaison organizations. CONCLUSION: A multipronged, adaptive approach led to the successful recruitment of diverse community-residing elders with memory impairment for an intervention trial. Key factors for success included using a range of evidence-supported outreach strategies, forming key strategic community partnerships, seeking regular stakeholder input through all research phases, and obtaining "buy-in" from community stakeholders by aligning study objectives with perceived unmet community needs.

A randomized controlled trial of a community-based dementia care coordination intervention: effects of MIND at Home on caregiver outcomes.

OBJECTIVE: To assess whether MIND at Home, a community-based, multicomponent, care coordination intervention, reduces unmet caregiving needs and burden in informal caregivers of persons with memory disorders. METHODS: An 18-month randomized controlled trial of 289 community-living care recipient (CR)-caregiver (informal caregivers, i.e., unpaid individuals who regularly assisted the CR) dyads from 28 postal code areas of Baltimore, Maryland was conducted. All dyads and the CR's primary care physician received the written needs assessment results and intervention recommendations. Intervention dyads then received an 18-month care coordination intervention delivered by nonclinical community workers to address unmet care needs through individualized care planning, referral and linkage to dementia services, provision of caregiver dementia education and skill-building strategies, and care progress monitoring by an interdisciplinary team. Primary outcome was total percent of unmet caregiver needs at 18 months. Secondary outcomes included objective and subjective caregiver burden measures, quality of life (QOL), and depression. RESULTS: Total percent of unmet caregiver needs declined in both groups from baseline to 18 months, with no statistically significant between-group difference. No significant group differences occurred in most caregiver burden measures, depression, or QOL. There was a potentially clinically relevant reduction in self-reported number of hours caregivers spent with the CR for MIND participants compared with control subjects. CONCLUSION: No statistically significant impacts on caregiver outcomes were found after multiple comparison adjustments. However, MIND at Home appeared to have had a modest and clinically meaningful impact on informal caregiver time spent with CRs.

Correlates of objective and subjective measures of caregiver burden among dementia caregivers: influence of unmet patient and caregiver dementia-related care needs.

BACKGROUND: This study examines the relationship of unmet dementia-related care needs of community-dwelling persons, and their caregivers (CGs), to measures of caregiver burden. METHODS: Cross-sectional baseline data were analyzed from participants in a dementia care coordination trial of community-residing persons with dementia (PWD) (n = 254) and their caregivers (n = 246). Participants were recruited from Northwest Baltimore, Maryland. The Zarit Burden Inventory (ZBI) was used to measure subjective caregiver burden. Objective burden was measured by estimating the total hours per week spent doing things for the PWD and/or how many hours CGs missed paid work in the prior month due to caregiving responsibilities. The Johns Hopkins Dementia Care Needs Assessment was used to identify unmet dementia-related care needs. Bivariate and multivariate linear regressions examined the relationship of unmet needs, demographic, clinical, or functional characteristics with caregiver burden measures. RESULTS: In adjusted multivariable models, patient neuropsychiatric symptoms and caregiver unmet emotional needs explained 22% of the variance in ZBI scores. In adjusted multivariable models, caregiver need for respite, patient functional dependency, and caregiver unmet specialty medical needs explained 26% of the variance in the hours per week spent caregiving. PWD's level of functional dependency was the sole correlate of missed time at work, explaining 11% of the variance. CONCLUSIONS: Addressing potentially modifiable unmet caregiver needs may reduce subjective and objective caregiver burden.

Researchers' perspectives on the role of study partners in dementia research.

BACKGROUND: Study partners for dementia research participants are vital to the research process, but little is known about their role, responsibilities, and experiences. Study partners are usually family members or friends - often the patient's informal caregiver - who are knowledgeable about and usually accompany the participant to study visits. This study examines researchers' perspectives on the role of study partners in dementia research. METHODS: Qualitative data collection and analytic methods were used. Semi-structured individual interviews with principal investigators, study coordinators, and research nurses (i.e. researchers; n = 17) at two academic research sites were recorded, transcribed, and content analyzed to identify themes in the data. RESULTS: According to researchers, study partners either make or help make research enrollment and post-enrollment decisions, serve as knowledgeable informants for the participants, manage the logistics that enable participants to comply with a study's protocol, and provide comfort and encouragement for the patient to engage in and complete a study. Researchers describe ideal qualities of study partners as being able to provide reliable information, being dependable and adherent to the protocol, and not expecting a benefit. They also report that study partners may face both practical and emotional challenges during research participation. However, researchers believe that study partners derive dementia-related education, caregiver support, and satisfaction from their involvement in research. CONCLUSIONS: Investigators, potential study partners, and institutional review boards should be aware of study partners' research responsibilities, challenges, and their interests as caregivers.

Understanding clinician perception of common presentations in South Asians seeking mental health treatment and determining barriers and facilitators to treatment.

BACKGROUND: Little is known about the presentation of mental health symptoms among South Asians living in the US. OBJECTIVE: To explore mental health symptom presentation in South Asians in the US and to identify facilitators and barriers to treatment. DESIGN: Focus group study. PARTICIPANTS: Four focus groups were conducted with 7-8 participants in each group. All participants (N = 29) were clinicians who had been involved in the care of South Asian patients with emotional problems and/or mental illness in the US. APPROACH: Qualitative content analysis. RESULTS: Key themes identified included: generational differences in symptom presentation, stress was the most common symptom for younger South Asians (<40 years of age), while major mental illnesses such as severe depression, psychosis and anxiety disorder were the primary symptoms for older South Asians (>40 years of age). Substance abuse and verbal/physical/sexual abuse were not uncommon but were often not reported spontaneously. Stigma and denial of mental illness were identified as major barriers to treatment. Facilitators for treatment included use of a medical model and conducting systematic but patient-centered evaluations. CONCLUSIONS: South Asians living in the US present with a variety of mental health symptoms ranging from stress associated with acculturation to major mental illnesses. Facilitating the evaluation and treatment of South Asians with mental illness requires sensitivity to cultural issues and use of creative solutions to overcome barriers to treatment.

A multidimensional home-based care coordination intervention for elders with memory disorders: the maximizing independence at home (MIND) pilot randomized trial.

OBJECTIVES: To assess whether a dementia care coordination intervention delays time to transition from home and reduces unmet needs in elders with memory disorders. DESIGN: 18-month randomized controlled trial of 303 community-living elders. SETTING: 28 postal code areas of Baltimore, MD. PARTICIPANTS: Age 70+ years, with a cognitive disorder, community-living, English-speaking, and having a study partner available. INTERVENTION: 18-month care coordination intervention to systematically identify and address dementia-related care needs through individualized care planning; referral and linkage to services; provision of dementia education and skill-building strategies; and care monitoring by an interdisciplinary team. MEASUREMENTS: Primary outcomes were time to transfer from home and total percent of unmet care needs at 18 months. RESULTS: Intervention participants had a significant delay in time to all-cause transition from home and the adjusted hazard of leaving the home was decreased by 37% (Hazard ratio: 0.63, 95% Confidence Interval: 0.42-0.94) compared with control participants. Although there was no significant group difference in reduction of total percent of unmet needs from baseline to 18 months, the intervention group had significant reductions in the proportion of unmet needs in safety and legal/advance care domains relative to controls. Intervention participants had a significant improvement in self-reported quality of life (QOL) relative to control participants. No group differences were found in proxy-rated QOL, neuropsychiatric symptoms, or depression. CONCLUSIONS: A home-based dementia care coordination intervention delivered by non-clinical community workers trained and overseen by geriatric clinicians led to delays in transition from home, reduced unmet needs, and improved self-reported QOL.

Decision making for participation in dementia research.

OBJECTIVES: This study examined the decision-making process used by individuals asked to participate in dementia research and their opinions on how future proxy research decisions would or should be made, including participants' preferred ethical standards for decision making. DESIGN: Cross-sectional qualitative methods. SETTING: University research institutions. PARTICIPANTS: Informants were 39 of 46 individuals with cognitive impairment (i.e., subjects) who were asked to join one of six dementia studies and 46 study partners or surrogate decision makers. MEASUREMENTS: Semistructured individual interviews were audio recorded and transcribed for content analysis. RESULTS: Within dyads, subjects and surrogates often differed in their perspectives on how decisions were made regarding whether to join a study, and no single method was identified as a predominant approach. Although there was only fair agreement within dyads on who ultimately made the decision, subjects and surrogates most often said it was the subject. For future proxy research decisions, subjects and surrogates most often preferred the ethical standard of best interests and least often favored substituted judgment. However, many participants preferred a combination of best interests and substituted judgment or a more complex approach that also considers the interests of others. CONCLUSIONS: Individuals with mild to moderate cognitive impairment can and do engage to some extent in the decision-making process for dementia research and can discuss their opinions on how they would want such decisions made for them in the future. These findings support the recommended approach for obtaining proxy consent and subject assent if the individual lacks consent capacity.

Unmet needs of community-residing persons with dementia and their informal caregivers: findings from the maximizing independence at home study.

OBJECTIVES: To determine the prevalence and correlates of unmet needs in a sample of community-residing persons with dementia (PWD) and their informal caregivers. DESIGN: Analysis of cross-sectional, baseline participant characteristics before randomization in a care coordination intervention trial. SETTING: Baltimore, Maryland. PARTICIPANTS: Community-residing PWD (n=254) and their informal caregivers (n=246). MEASUREMENTS: In-home assessments of dementia-related needs based on the Johns Hopkins Dementia Care Needs Assessment. Bivariate and multivariate regression analyses were conducted to identify demographic, socioeconomic, clinical, functional, and quality-of-life correlates of unmet needs. RESULTS: The mean number of unmet needs was 7.7±4.8 in PWD and 4.6±2.3 in caregivers, with almost all PWD (99%) and caregivers (97%) having one or more unmet needs. Unmet needs in PWD were significantly greater in those with higher cognitive function. Ninety percent of PWD had unmet safety needs, more than half had unmet needs for meaningful activities, and almost one-third had not received a prior evaluation or diagnosis. Higher unmet needs in PWD was significantly associated with nonwhite race, lower income, less impairment in activities of daily living, and more symptoms of depression. For caregivers, more than 85% had unmet needs for resource referrals and caregiver education. Higher unmet caregiver needs was significantly associated with nonwhite race, less education, and more symptoms of depression. CONCLUSION: Many community-residing PWD and their caregivers have unmet dementia-related needs for care, services, and support. Providers should be aware that unmet needs may be higher in minority and low-income community residents, caregivers with lower education, and individuals with early-stage dementia. Identifying and treating symptoms of depression in PWD and caregivers may enable them to address their other unmet needs.

Predictors of progression to severe Alzheimer's disease in an incidence sample.

BACKGROUND: Little is known about factors influencing time to severe Alzheimer's disease (AD). METHODS: Incident cases of AD in the cache county memory study were identified. Severe AD was defined as mini-mental state examination score of ≤10 or Clinical Dementia Rating Scale score of 3; cases with either mini-mental state examination score of ≥16 or clinical dementia rating <2 were not categorized as severe AD. Kaplan-Meier, log-rank tests, and Cox analyses were used to identify demographic, clinical, and genetic correlates of time to progression to severe AD. RESULTS: Sixty-eight of 335 cases of incident AD developed severe dementia. In bivariate analyses, female gender, less than high school education, at least one clinically significant Neuropsychiatric Inventory domain at baseline, and the youngest and oldest ages exhibited shorter time to severe AD. In competing risk analysis, subjects with mild or at least one clinically significant neuropsychiatric inventory domain score, and subjects with worse health were more likely to progress to severe dementia or death. CONCLUSIONS: Demographic and clinical variables predict progression to severe AD. Further study should examine whether these relationships are causal or correlational.

Advanced dementia: state of the art and priorities for the next decade.

Dementia is a leading cause of death in the United States. This article outlines the current understanding of advanced dementia and identifies research priorities for the next decade. Research over the past 25 years has largely focused on describing the experience of patients with advanced dementia. This work has delineated abundant opportunities for improvement, including greater recognition of advanced dementia as a terminal illness, better treatment of distressing symptoms, increased access to hospice and palliative care services, and less use of costly and aggressive treatments that may be of limited clinical benefit. Addressing those opportunities must be the overarching objective for the field in the coming decade. Priority areas include designing and testing interventions that promote high-quality, goal-directed care; health policy research to identify strategies that incentivize cost-effective and evidence-based care; implementation studies of promising interventions and policies; and further development of disease-specific outcome measures. There is great need and opportunity to improve outcomes, contain expenditures, reduce disparities, and better coordinate care for the millions of persons in the United States who have advanced dementia.

Race and cognitive decline among community-dwelling elders with mild cognitive impairment: findings from the Memory and Medical Care Study.

OBJECTIVE: Previous studies have reported conflicting findings on the relationship between race and cognitive decline in elders with dementia. Few studies have examined the role of race in cognitive decline in mild cognitive impairment (MCI). We investigate the relationship between race and cognitive decline in participants with MCI in a community-based, longitudinal study of cognitively impaired elders. METHOD: Based on a validated method utilizing a neuropsychiatric battery, 133 subjects [mean age: 78.7 years (SD = 6.5); female: 112 (76.7%); black: 59 (44.4%)] out of 512 participants in the Memory and Medical Care Study were diagnosed with MCI. The main outcome measure was the Telephone Interview for Cognitive Status (TICS) score over three years. Other baseline subject characteristics (demographics, health-related variables, behavioral, and psychiatric symptoms) were included in the analysis. RESULTS: Overall, the three-year decline in mean TICS score was significantly higher among African Americans than non-African Americans [3.31 (SD: 7.5) versus 0.96 (SD: 3.0), t-value = 1.96, p-value = 0.05]. General estimating equation analyses revealed that African American race was associated with a faster rate of cognitive decline in all models. CONCLUSION: The rate of cognitive decline in MCI appears to be faster in African Americans than non-African Americans in the community. Diagnosis of MCI among African American elders could lead to early interventions to prevent or delay cognitive decline in the future.

Quality of life of community-residing persons with dementia based on self-rated and caregiver-rated measures.

PURPOSE: To identify correlates of self-rated and caregiver-rated quality of life (QOL) in community-residing persons with dementia (PWD) for intervention development. METHODS: Cross-sectional data of 254 PWD and their caregivers participating in a clinical trial were derived from in-home assessments. Self-rated QOL was measured with the Quality of Life-Alzheimer Disease (QOL-AD) scale, and caregiver-rated QOL was measured using the QOL-AD and Alzheimer Disease-Related Quality of Life (ADRQL) scales. Multivariate modeling identified correlates of the PWD' QOL. RESULTS: Self-rated QOL was related significantly to participant race, unmet needs, depression, and total medications. Caregiver-rated QOL-AD scores were significantly associated with participant function, unmet needs, depression, and health problems and with caregiver burden and self-rated health. Significant correlates of ADRQL scores included neuropsychiatric symptom severity, functional and cognitive impairment, and caregiver burden and depression. CONCLUSIONS: Correlates of QOL in community-residing PWD depend on who rates the PWD's QOL and which measure is used. Addressing health problems, medication use, and dementia-related unmet needs, reducing functional dependency, and treating neuropsychiatric symptoms in PWD, while reducing caregiver burden and depression, may maximize QOL in those with dementia.
