Dementia Prevention and Treatment: A Narrative Review

Importance

Dementia affects 10% of those 65 years or older and 35% of those 90 years or older, often with profound cognitive, behavioral, and functional consequences. As the baby boomers and subsequent generations age, effective preventive and treatment strategies will assume increasing importance.

Observations

Preventive measures are aimed at modifiable risk factors, many of which have been identified. To date, no randomized clinical trial data conclusively confirm that interventions of any kind can prevent dementia. Nevertheless, addressing risk factors may have other health benefits and should be considered. Alzheimer disease can be treated with cholinesterase inhibitors, memantine, and antiamyloid immunomodulators, with the last modestly slowing cognitive and functional decline in people with mild cognitive impairment or mild dementia due to Alzheimer disease. Cholinesterase inhibitors and memantine may benefit persons with other types of dementia, including dementia with Lewy bodies, Parkinson disease dementia, vascular dementia, and dementia due to traumatic brain injury. Behavioral and psychological symptoms of dementia are best treated with nonpharmacologic management, including identifying and mitigating the underlying causes and individually tailored behavioral approaches. Psychotropic medications have minimal evidence of efficacy for treating these symptoms and are associated with increased mortality and clinically meaningful risks of falls and cognitive decline. Several emerging prevention and treatment strategies hold promise to improve dementia care in the future.

Conclusions and Relevance

Although current prevention and treatment approaches to dementia have been less than optimally successful, substantial investments in dementia research will undoubtedly provide new answers to reducing the burden of dementia worldwide.

Validation of a Rule-Based ICD-10-CM Algorithm to Detect Fall Injuries in Medicare Data

BACKGROUND

Diagnosis-code-based algorithms to identify fall injuries in Medicare data are useful for ascertaining outcomes in interventional and observational studies. However, these algorithms have not been validated against a fully external reference standard, in ICD-10-CM, or in Medicare Advantage (MA) data.

METHODS

We linked self-reported fall injuries leading to medical attention (FIMA) from the Strategies to Reduce Injuries and Develop Confidence in Elders (STRIDE) trial (reference standard) to Medicare fee-for-service (FFS) and MA data from 2015-2019. We measured the area under the receiver operating characteristic curve (AUC) based on sensitivity and specificity of a diagnosis-code-based algorithm against the reference standard for presence or absence of ≥1 FIMA within a specified window of dates, varying the window size to obtain points on the curve. We stratified results by source (FFS versus MA), trial arm (intervention versus control), and STRIDE's ten participating healthcare systems.

RESULTS

Both reference standard data and Medicare data were available for 4941 (of 5451) participants. The reference standard and algorithm identified 2054 and 2067 FIMA, respectively. The algorithm had 45% sensitivity (95% confidence interval [CI], 43%-47%) and 99% specificity (95% CI, 99%-99%) to identify reference standard FIMA within the same calendar month. The AUC was 0.79 (95% CI, 0.78-0.81) and was similar by FFS or MA data source or trial arm, but showed variation among STRIDE healthcare systems (AUC range by healthcare system, 0.71 to 0.84).

CONCLUSIONS

An ICD-10-CM algorithm to identify fall injuries demonstrated acceptable performance against an external reference standard, in both MA and FFS data.

The dementia care study (D-CARE): Recruitment strategies and demographic characteristics of participants in a pragmatic randomized trial of dementia care

INTRODUCTION

Pragmatic research studies that include diverse dyads of persons living with dementia (PLWD) and their family caregivers are rare.

METHODS

Community-dwelling dyads were recruited for a pragmatic clinical trial evaluating three approaches to dementia care. Four clinical trial sites used shared and site-specific recruitment strategies to enroll health system patients.

RESULTS

Electronic health record (EHR) queries of patients with a diagnosis of dementia and engagement of their clinicians were the main recruitment strategies. A total of 2176 dyads were enrolled, with 80% recruited after the onset of the pandemic. PLWD had a mean age of 80.6 years (SD 8.5), 58.4% were women, and 8.8% were Hispanic/Latino, and 11.9% were Black/African American. Caregivers were mostly children of the PLWD (46.5%) or spouses/partners (45.2%), 75.8% were women, 9.4% were Hispanic/Latino, and 11.6% were Black/African American.

DISCUSSION

Health systems can successfully enroll diverse dyads in a pragmatic clinical trial.

Demographics, Symptoms, Psychotropic Use, and Caregiver Distress in Patients With Early vs Late Onset Dementia

BACKGROUND

Understanding experiences and challenges faced by persons living with Early-Onset Dementia (EOD) compared to individuals diagnosed with Late-Onset Dementia (LOD) is important for the development of targeted interventions.

OBJECTIVE

Describe differences in sociodemographic, neuropsychiatric behavioral symptoms, caregiver characteristics, and psychotropic use.

DESIGN, SETTING, PARTICIPANTS

Cross-sectional, retrospective study including 908 UCLA Alzheimer's Dementia Care Program participants (177 with EOD and 731 with LOD).

MEASUREMENTS

Onset of dementia was determined using age at program enrollment, with EOD defined as age <65 years and LOD defined as age >80 years. Sociodemographic and clinical characteristics were measured once at enrollment. Behavioral symptoms were measured using the Neuropsychiatric Inventory Questionnaire (NPI-Q) severity score and caregiver distress was measured using the NPI-Q distress score. Medications included antipsychotic, antidepressant, benzodiazepines and other hypnotics, antiepileptics, and dementia medications.

RESULTS

EOD compared to LOD participants were more likely men, college graduates, married, live alone, and have fewer comorbidities. EOD caregivers were more often spouses (56% vs 26%, p <0.01), whereas LOD caregivers were more often children (57% vs 10%, p <0.01). EOD was associated with lower odds of being above the median (worse) NPI-Q severity (adjusted odds ratio [aOR], 0.58; 95% CI 0.35-0.96) and NPI-Q distress scores (aOR, 0.53; 95% CI 0.31-0.88). Psychotropic use did not differ between groups though symptoms were greater for LOD compared to EOD.

CONCLUSION

Persons with EOD compared to LOD had sociodemographic differences, less health conditions, and fewer neuropsychiatric symptoms. Future policies could prioritize counseling for EOD patients and families, along with programs to support spousal caregivers of persons with EOD.

Proving the Geriatrician's worth

Association between physicians' geriatric training and patterns of end-of-life care delivered to persons with dementia

BACKGROUND

Geriatric training is designed to prepare physicians to meet the complex needs of older adults, including persons with dementia at the end-of-life (EOL) stage. We sought to compare patterns of EOL care delivered to persons with dementia between physicians with versus without geriatric training.

METHODS

We conducted a cross-sectional study of a 20% random sample of fee-for-service Medicare beneficiaries with dementia who died in 2016-2018 (n = 99,631). We attributed beneficiaries to a physician who had the largest number of primary care visits during the last 6 months of life and determined whether the physician was trained in geriatrics. Our outcome measures included: (i) advance care planning (ACP) and palliative care (e.g., ACP, hospice enrollment in the last 90 days of life), and (ii) high-intensity EOL care (e.g., emergency department visits or hospital admissions in the last 30 days of life).

RESULTS

Beneficiaries with dementia under the care of physicians with geriatric training had a higher proportion of ACP (adjusted proportion, 15.8% vs. 13.0%; p < 0.001 after accounting for multiple comparisons), palliative care counseling (22.4% vs. 20.9%; p = 0.01), and hospice enrollment (63.7% vs. 60.6%; p < 0.001). Geriatric training was also associated with a lower proportion of emergency department visits (55.1% vs. 59.1%; p < 0.001), hospital admissions (48.8% vs. 52.3%; p < 0.001), ICU admissions (24.9% vs. 27.4%; p < 0.001), use of mechanical ventilation (11.2% vs. 13.0%; p < 0.001), and use of cardiopulmonary resuscitation (2.1% vs. 2.4%; p = 0.03) in the last 30 days of life. There was no evidence that the placement of feeding tubes differed between the two groups.

CONCLUSIONS

Physicians' geriatric training was associated with the receipt of more ACP and palliative care and less intensive EOL care among persons with dementia. Provision of geriatric training for physicians may have the potential to improve the quality of EOL care delivered to persons with dementia.

Costs of fall injuries in the STRIDE study: an economic evaluation of healthcare system heterogeneity and heterogeneity of treatment effect

OBJECTIVES

The Strategies to Reduce Injuries and Develop Confidence in Elders (STRIDE) Study cluster-randomized 86 primary care practices in 10 healthcare systems to a patient-centered multifactorial fall injury prevention intervention or enhanced usual care, enrolling 5451 participants. We estimated total healthcare costs from participant-reported fall injuries receiving medical attention (FIMA) that were averted by the STRIDE intervention and tested for healthcare-system-level heterogeneity and heterogeneity of treatment effect (HTE).

METHODS

Participants were community-dwelling adults age ≥ 70 at increased fall injury risk. We estimated practice-level total costs per person-year of follow-up (PYF), assigning unit costs to FIMA with and without an overnight hospital stay. Using independent variables for treatment arm, healthcare system, and their interaction, we fit a generalized linear model with log link, log follow-up time offset, and Tweedie error distribution.

RESULTS

Unadjusted total costs per PYF were $2,034 (intervention) and $2,289 (control). The adjusted (intervention minus control) cost difference per PYF was -$167 (95% confidence interval (CI), -$491, $216). Cost heterogeneity by healthcare system was present (p = 0.035), as well as HTE (p = 0.090). Adjusted total costs per PYF in control practices varied from $1,529 to $3,684 for individual healthcare systems; one system with mean intervention minus control costs of -$2092 (95% CI, -$3,686 to -$944) per PYF accounted for HTE, but not healthcare system cost heterogeneity.

CONCLUSIONS

We observed substantial heterogeneity of healthcare system costs in the STRIDE study, with small reductions in healthcare costs for FIMA in the STRIDE intervention accounted for by a single healthcare system.

The Other Dementia Breakthrough-Comprehensive Dementia Care

This Viewpoint describes barriers to comprehensive dementia care and proposes strategies for overcoming them.

Life satisfaction among persons living with dementia and those without dementia

BACKGROUND

Despite possible major adverse cognitive, physical, social, and behavioral consequences, little is known about how persons living with dementia perceive satisfaction with life, a key component of well-being. We sought to examine (i) whether persons living with dementia perceive a lower level of satisfaction compared to their peers without dementia and (ii) whether the associations between individual characteristics and life satisfaction are different between persons living with and without dementia.

METHODS

Using a nationally representative sample of community-dwelling older adults aged ≥70 years in the U.S. from the Health and Retirement Study, we compared scores on the Satisfaction with Life Scale (SWLS), a self-reported 5-item scale ranging from 1 to 7 (more satisfaction), between persons with probable dementia (n = 341) and those without (n = 5530), adjusting for individual characteristics. We also tested whether the associations between the individual characteristics and SWLS differ by dementia status.

RESULTS

Scores on SWLS did not differ between persons with probable dementia and those without when adjusting for individual characteristics including limitations in activities of daily living (ADL) (adjusted difference, -0.09; 95% CI, -0.33 to +0.15; p-value, 0.45). However, dementia status was associated with lower life satisfaction through the mediation of limitations in ADL (total effect, -0.29; bootstrapped 95% CI, -0.47 to -0.12). Most individual characteristics associated with lower life satisfaction were similar in the two groups, including younger age, more limitations in ADL, and depression. Less wealth was associated with lower satisfaction among persons without dementia but not among those with probable dementia.

CONCLUSIONS

Dementia status was only modestly associated with lower life satisfaction through the mediation of limitations in ADL among participants who were able to provide response. Future research is warranted to determine whether life satisfaction can be used as a meaningful outcome when evaluating well-being among persons living with dementia.

A population-based, electronic health record-guided approach to improve the quality of dementia care

BACKGROUND

The quality of care of the 6.5 million Americans living with dementia has been suboptimal, leading to worse outcomes and higher costs. Few health systems have formal systems in place to guide the care of these patients. To help improve the care of persons living with dementia, we developed and preliminarily evaluated the effectiveness of electronic health record (EHR)-generated recommendations for patients with dementia.

METHODS

This quality improvement study was conducted from October 2020 through June 2022 at a single academic healthcare system and included patients identified as having dementia on their problem list and their physicians. Ten (seven outpatient and three inpatient) algorithms based on clinical logic and evidence were embedded in an EHR system to generate specific recommendations based on combinations of utilization, diagnosis, and medications. The number of each type of recommendation generated, and orders for each type of recommendation were recorded, as well as physician's perceptions of this approach.

RESULTS

Three thousand six hundred and nine recommendations on 763 patients were triggered by the algorithms in the outpatient setting, and 185 referrals were placed. The most common recommendations were for ongoing care through the UCLA Alzheimer's and Dementia Care program, Palliative Care, the Extensivist Clinic, Urogynecology, and Clinical Pharmacy. The most commonly acted upon by providers were recommendations for referral to Pharmacists and the UCLA Alzheimer's and Dementia Care program. The most common reason for not responding to specific recommendations was that these were not perceived as relevant to the patient. Compared to general medicine physicians, geriatricians felt more comfortable managing dementia care without a referral to a service (23% (95% CI 15%-34%) versus 3% (95% CI 0%-17%), p = 0.012) and less commonly felt the recommendation was appropriate (1% (95% CI 0%-7%) versus 13% (95% CI 4%-30%), p = 0.02).

CONCLUSIONS

EHR-generated algorithms can help guide patients with dementia to appropriate clinical services.

Chronic disease management: why dementia care is different

With the rise in the population of older adults, the number of individuals living with chronic diseases that need management will increase dramatically. Successful programs have been developed for chronic conditions (eg, heart failure, diabetes, asthma, chronic obstructive pulmonary disease) that use principles of self-management, monitoring, and care coordination. However, because of the effects of dementia on the mind including behavioral complications, the progressive loss of capacity for affected individuals to participate in care or decision-making, the devastating effects on care partners, and the scope of disease management beyond medical issues, the management of dementia is different and demands different approaches. The success of dementia management will depend upon how well the care provided is able to maximize the function, independence, and dignity of the individual living with dementia while minimizing care partner strain and burnout.

Engagement of older adults in STRIDE's multifactorial fall injury prevention intervention

BACKGROUND

Evidence-based multifactorial fall prevention interventions in clinical practice have been less effective than expected. One plausible reason is that older adults' engagement in fall prevention care is suboptimal.

METHODS

This was a post-hoc analysis of 2403 older adults' engagement in a multifactorial fall prevention intervention in the Strategies to Reduce Injuries and Develop Confidence in Elders (STRIDE) pragmatic trial. Based on the direct clinical care level of the Patient and Family Continuum of Engagement (CE) framework, three indicators of progressively interactive engagement were assessed: (1) Consultation (receiving information), (2) Involvement (prioritizing risks), and (3) Partnership (identifying prevention actions). Drop off at each step was determined as well as predictors of engagement.

RESULTS

The participants' engagement waned with increasingly interactive CE domains. Although all participants received information about their positive fall risk factors (consultation) and most (51%-96%) prioritized them (involvement), fewer participants (33%-55%) identified fall prevention actions (partnership) for most of their risk factors, except for strength gait or balance problems (95%). More participants (70%) identified home exercises than other actions. Finally, fall prevention actions were identified more commonly among participants who received two visits compared to one (OR = 2.33 [95% CI, 2.06-2.64]), were ≥80 years old (OR = 1.83 [95% CI, 1.51-2.23]), and had fewer fall risk factors (OR = 0.90 [95% CI, 0.83-0.99]).

CONCLUSIONS

The drop-off in participants' engagement based on the level of their interaction with clinicians suggests that future multifactorial fall prevention interventions need to be more focused on interactive patient-clinician partnerships that help older adults increase and maintain fall prevention actions. Our analyses suggest that more frequent contact with clinicians and more monitoring of the implementation and outcomes of Fall Prevention Care Plans could potentially improve engagement and help older adults maintain fall prevention actions.

Effect of the STRIDE fall injury prevention intervention on falls, fall injuries, and health-related quality of life

BACKGROUND

Falls are common in older adults and can lead to severe injuries. The Strategies to Reduce Injuries and Develop Confidence in Elders (STRIDE) trial cluster-randomized 86 primary care practices across 10 health systems to a multifactorial intervention to prevent fall injuries, delivered by registered nurses trained as falls care managers, or enhanced usual care. STRIDE enrolled 5451 community-dwelling older adults age ≥70 at increased fall injury risk.

METHODS

We assessed fall-related outcomes via telephone interviews of participants (or proxies) every 4 months. At baseline, 12 and 24 months, we assessed health-related quality of life (HRQOL) using the EQ-5D-5L and EQ-VAS. We used Poisson models to assess intervention effects on falls, fall-related fractures, fall injuries leading to hospital admission, and fall injuries leading to medical attention. We used hierarchical longitudinal linear models to assess HRQOL.

RESULTS

For recurrent event models, intervention versus control incidence rate ratios were 0.97 (95% confidence interval [CI], 0.93-1.00; p = 0.048) for falls, 0.93 (95% CI, 0.80-1.08; p = 0.337) for self-reported fractures, 0.89 (95% CI, 0.73-1.07; p = 0.205) for adjudicated fractures, 0.91 (95% CI, 0.77-1.07; p = 0.263) for falls leading to hospital admission, and 0.97 (95% CI, 0.89-1.06; p = 0.477) for falls leading to medical attention. Similar effect sizes (non-significant) were obtained for dichotomous outcomes (e.g., participants with ≥1 events). The difference in least square mean change over time in EQ-5D-5L (intervention minus control) was 0.009 (95% CI, -0.002 to 0.019; p = 0.106) at 12 months and 0.005 (95% CI, -0.006 to 0.015; p = 0.384) at 24 months.

CONCLUSIONS

Across a standard set of outcomes typically reported in fall prevention studies, we observed modest improvements, one of which was statistically significant. Future work should focus on patient-, practice-, and organization-level operational strategies to increase the real-world effectiveness of interventions, and improving the ability to detect small but potentially meaningful clinical effects.

Dissemination of a successful dementia care program: Lessons to facilitate spread of innovations

BACKGROUND

Despite the effectiveness of innovations to improve the care of persons with dementia, there has been limited diffusion of these into widespread clinical practice. We aimed to identify common barriers and address them directly in the initial phase of dissemination of a successful dementia care program.

METHODS

Description of and early experience with a dissemination strategy of the UCLA Alzheimer's and Dementia Care Program to health care systems nationwide. We measured site-identified goals for the program and indicators of success, number of adopting sites, and participants in their programs.

RESULTS

From January 2019 to December 2021, 80 sites expressed interest in adopting the program, 14 (18%) sites adopted it, and 10 of these sites have begun caring for patients. Another 4 sites have implemented the program as part of a randomized clinical trial. To date, over 1690 persons living with dementia and their caregivers have received Alzheimer's and Dementia Care (ADC) care at 14 adopting sites. Key lessons from the early dissemination efforts include the importance of identifying a strong product champion at the adopting site, creating a business case for adoption, training of clinical staff and adapting the model to fit local cultures and workflow, as well as recognizing the likely long length of time needed for the decision to adopt and implementation process.

CONCLUSIONS

Despite many obstacles to dissemination, with local champions and technical assistance, successful innovations in dementia care can be implemented in diverse health systems. The ability to adopt sites to bring the program to full scale and achieve comparable outcomes to the original program remains to be determined.

Dissemination of a successful dementia care program: Lessons from early adopters

BACKGROUND

Evidence-based models for providing effective and comprehensive care for Alzheimer's disease and related dementias exist but have yet to be successfully implemented at scale. The Alzheimer's and Dementia Care Program (ADC Program) is an effective comprehensive dementia care model that is being disseminated across the United States. This qualitative study examines barriers and facilitators to implementing the model among early adopting sites.

METHODS

This study included semi-structured interviews with a total of 21 clinical site leaders and Dementia Care Specialists from a total of 11 sites across the US. Interviews were audio recorded, transcribed, and coded using Dedoose qualitative analysis software. Coding scheme development and data interpretation were informed by Rogers' Diffusion of Innovations framework.

RESULTS

Key themes are organized in line with Rogers' framework. These include: the innovation-decision process, implementation and characteristics of the innovation, and sustainability.

CONCLUSIONS

Across the three overarching themes presented in this manuscript, the importance of engagement from site leaders, the multifaceted nature of the dementia care specialist role, and the value of technical assistance from qualified experts are apparent. However, for this work to continue to be successful, there needs to be more appropriate payment to cover needed services and a mechanism for supporting comprehensive dementia care over time.

Overwhelmed: a Dementia Caregiver Vital Sign

BACKGROUND

The emotional stress of caring for someone with Alzheimer's disease and related dementias is high and results in adverse effects on caregivers and the persons living with disease. In preliminary work, caregiver reports of regularly feeling "completely overwhelmed" were associated with lack of measurable clinical benefit from a comprehensive dementia care program.

OBJECTIVE

To examine the sociodemographic and clinical characteristics of all caregivers who felt overwhelmed at entry into a comprehensive dementia care program, the trajectory of this symptom over 1 year, and its predictive value for 1-year caregiver outcomes.

DESIGN

Longitudinal cohort study SETTING: Academic health center PARTICIPANTS: Caregivers of patients enrolled in a comprehensive dementia care program EXPOSURES: Caregiver report of feeling "completely overwhelmed" at baseline MAIN MEASURES: Caregiver report of feeling "completely overwhelmed" at baseline and 1 year, and validated scales of caregiver strain, distress, depressive symptoms, burden, mortality, and long-term nursing home placement KEY RESULTS: Compared to caregivers who were not overwhelmed, overwhelmed caregivers had more distress from behavioral symptoms of the person living with dementia, worse depression scores, and higher composite dementia burden scores at baseline. They also had worse depressive symptoms, strain, and composite burden scores at 1 year, after adjustment for baseline scores. Having an overwhelmed caregiver did not predict long-term nursing home placement or mortality among persons with dementia.

CONCLUSIONS

A single question about whether a caregiver is overwhelmed might indicate caregivers who have considerable current and future symptom burden and who may benefit from increased support and resources.

Trends in advance care planning and end-of-life care among persons living with dementia requiring surrogate decision-making

BACKGROUND

Previous studies have demonstrated positive impacts of advance care planning (ACP) on end-of-life (EOL) care. We sought to examine trends in ACP and EOL care intensity among persons living with dementia who required surrogate decision-making in their final days of life.

METHODS

We analyzed the participants of the Health and Retirement Study (HRS), a nationally representative longitudinal panel study of U.S. residents, with dementia 70 years and older who required surrogate decision-making in the final days of life and died between 2000 and 2014. Based on surrogate reports after the death of a participant, our study measured the completion of three specific types of patient-engaged ACP (written EOL care instructions, assignment of a durable power of attorney for healthcare, patient engagement in EOL care discussions) and four measures of EOL care in the final days of life (death in hospital, receipt of life-prolonging treatments, limiting or withholding certain treatments, and receipt of comfort-oriented care). All analyses accounted for the complex survey design of HRS.

RESULTS

Among 870 adults (weighted N = 2,812,380) with dementia who died in 2000-2014 and required surrogate decision-making at EOL, only 34.8% of patients participated in all three aspects of ACP, and there was not a significant increase in ACP completion between 2000 and 2014. The receipt of life-prolonging treatments in the final days of life has increased over time (adjusted change per year, 1.4 percentage points [pp]; 95% CI, 0.5 to 2.2 pp; P-for-trend = 0.002), while the percentage of death in hospital, limiting or withholding certain treatments, or comfort-oriented care did not change.

CONCLUSIONS

Our findings suggest that the rates of ACP completion have not increased over time despite its potential benefits and life-prolonging treatments are still common among PLWD who require surrogate decision-making, a population who might benefit greatly from early ACP.

Baseline pro-inflammatory gene expression in whole blood is related to adverse long-term outcomes after transcatheter aortic valve replacement: a case control study

BACKGROUND

Age-associated inflammation and immune system dysfunction have been implicated as mechanisms that increase risk for adverse long-term procedural outcomes in older adults. The purpose of this study was to investigate relationships between baseline inflammatory and innate antiviral gene expression and outcomes after transcatheter aortic valve replacement (TAVR) in older adults with severe aortic stenosis.

METHODS

We performed a retrospective case-control study comparing pre-procedural pro-inflammatory and Type 1 interferon (IFN) gene expression in 48 controls with favorable outcomes (alive 1 year after TAVR with improved quality of life [QoL]) versus 48 individuals with unfavorable outcomes (dead by 1 year or alive at 1 year but with reduced QoL). Gene expression was evaluated in whole blood via (1) pre-defined composite scores of 19 inflammation-associated genes and 34 Type I IFN response genes, and (2) pro-inflammatory and antiviral transcription factor activity inferred from promotor based bioinformatics analyses of genes showing > 25% difference in average expression levels across groups. All analyses were adjusted for age, gender, body mass index, diabetes, immunosuppression, cardiovascular disease (CVD), and frailty.

RESULTS

Relative to controls, those with unfavorable outcomes demonstrated higher expression of the pro-inflammatory gene composite prior to TAVR (p < 0.01) and bioinformatic indicators of elevated Nuclear Factor kB (p < 0.001) and Activator Protein 1 (p < 0.001) transcription factor activity, but no significant differences in Type I IFN-related gene expression.

CONCLUSIONS

These results demonstrate that a pro-inflammatory state prior to TAVR, independent of CVD severity and frailty status, is associated with worse long-term procedural outcomes.

Emerging topics in dementia care and services

BACKGROUND

The National Institute on Aging (NIA), in conjunction with the Department of Health and Human Services as part of the National Alzheimer's Project Act (NAPA), convened a 2020 Dementia Care, Caregiving, and Services Research Summit Virtual Meeting Series. This review article summarizes three areas of emerging science that are likely to grow in importance given advances in measurement, technologies, and diagnostic tests that were presented at the Summit.

RESULTS

Dr. Cassel discussed novel ethical considerations that have resulted from scientific advances that have enabled early diagnosis of pre-clinical dementia. Dr. Monin then summarized issues regarding emotional experiences in persons with dementia and their caregivers and care partners, including the protective impact of positive emotion and heterogeneity of differences in emotion by dementia type and individual characteristics that affect emotional processes with disease progression. Finally, Dr. Jared Benge provided an overview of the role of technologies in buffering the impact of cognitive change on real-world functioning and their utility in safety and monitoring of function and treatment adherence, facilitating communication and transportation, and increasing access to specialists in underserved or remote areas.

CONCLUSIONS

National policy initiatives, supported by strong advocacy and increased federal investments, have accelerated the pace of scientific inquiry and innovation related to dementia care and services but have raised some new concerns regarding ethics, disparities, and attending to individual needs, capabilities, and preferences.

Utility of a short, telephone-administered version of the Montreal Cognitive Assessment

BACKGROUND

Because of the COVID-19 pandemic, the ongoing D-CARE pragmatic trial of two models of dementia care management needed to transition to all data collection by telephone.

METHODS

For the first 1069 D-CARE participants, we determined the feasibility of administering a short 3-item version of the Montreal Cognitive Assessment (MoCA) to persons with dementia by telephone and examined the correlation with the full 12-item version.

RESULTS

The 3-item version could be administered by telephone in approximately 6 min and was highly correlated with the full MoCA (r = 0.78, p < 0.0001).

CONCLUSIONS

This brief version of the MoCA was feasible to collect by telephone and could be used as an alternative to the full MoCA, particularly if the purpose of cognitive assessment is characterization of study participants.

Barriers to implementation of STRIDE, a national study to prevent fall-related injuries

BACKGROUND/OBJECTIVES

Evaluations of complex models of care for older adults may benefit from simultaneous assessment of intervention implementation. The STRIDE (Strategies To Reduce Injuries and Develop confidence in Elders) pragmatic trial evaluated the effectiveness of a multifactorial intervention to reduce serious fall injuries in older adults. We conducted multi-level stakeholder interviews to identify barriers to STRIDE intervention implementation and understand efforts taken to mitigate these barriers.

DESIGN

Qualitative interviews with key informants.

SETTING

Ten clinical trial sites affiliated with practices that provided primary care for persons at increased risk for fall injuries.

PARTICIPANTS

Specially trained registered nurses working as Falls Care Managers (FCMs) who delivered the intervention (n = 13 individual interviews), Research Staff who supervised trial implementation locally (n = 10 group interviews, 23 included individuals), and members of Central Project Management and the National Patient Stakeholder Council who oversaw national implementation (n = 2 group interviews, six included individuals).

MEASUREMENTS

A semi-structured interview guide derived from the consolidated framework for implementation research (CFIR).

RESULTS

We identified eight key barriers to STRIDE intervention implementation. FCMs navigated complex relationships with patients and families while working with Research Staff to implement the intervention in primary care practices with limited clinical space, variable provider buy-in, and significant primary care practice staff and provider turnover. The costs of the intervention to individual patients and medical practices amplified these barriers. Efforts to mitigate these barriers varied depending on the needs and opportunities of each primary care setting.

CONCLUSION

The many barriers to implementation and the variability in how stakeholders addressed these locally may have affected the overall STRIDE intervention's effectiveness. Future pragmatic trials should incorporate simultaneous implementation aims to better understand how research interventions translate into clinical care that improves the lives of older adults.

Validation of a Brief Multi-Dimensional Assessment of Dementia Severity

BACKGROUND/OBJECTIVES

Briefer measures of symptoms and functional limitations may reduce assessment burden and facilitate monitoring populations of persons with dementia (PWD).

DESIGN

Prospective follow-up study.

SETTING

University-based dementia care management program.

PARTICIPANTS

1,091 PWD.

MEASUREMENTS

We assessed cognition (Mini Mental State Examination (MMSE)-11 tasks), neuropsychiatric symptom severity (Neuropsychiatric Inventory Questionnaire Severity Scale (NPIQ-S)-12 items), and functional ability (Activities of Daily Living (ADL)-6 items; Functional Activities Questionnaire (FAQ)-10 items). Item response theory was used to select subsets of items by identifying low item discrimination (<1.50), poor item fit (χ² ), local dependence (LD), and with difficulty similar to other items. We estimated correlations between original and shorter scales and compared their associations with mortality. We added two symptoms (trouble swallowing, coughing when eating) reflecting late-stage dementia complications, created a multi-dimensional dementia assessment composite, and examined its association with mortality.

RESULTS

Five MMSE tasks were eliminated: two with low discrimination, two with difficulty similar to other items, and one with poor fit. The remaining tasks were correlated with the full MMSE at r = 0.82. We retained three ADLs that were correlated with the total ADL set at r = 0.95 and kept five FAQ items that were not LD (correlation with full FAQ, r = 0.97). Associations with mortality were similar between the longer and shorter scales. A higher score on the composite (range 0-100) indicates worse dementia impact and was associated with mortality (hazard ratio (HR) per scale point: 1.03 (1.02-1.04)).

CONCLUSION

These brief assessments and dementia composite may reduce administration time while preserving validity.

Effect of a Multifactorial Fall Injury Prevention Intervention on Patient Well-Being: The STRIDE Study

BACKGROUND/OBJECTIVES

In the Strategies to Reduce Injuries and Develop Confidence in Elders (STRIDE) study, a multifactorial intervention was associated with a nonsignificant 8% reduction in time to first serious fall injury but a significant 10% reduction in time to first self-reported fall injury relative to enhanced usual care. The effect of the intervention on other outcomes important to patients has not yet been reported. We aimed to evaluate the effect of the intervention on patient well-being including concern about falling, anxiety, depression, physical function, and disability.

DESIGN

Pragmatic cluster-randomized trial of 5,451 community-living persons at high risk for serious fall injuries.

SETTING

A total of 86 primary care practices within 10 U.S. healthcare systems.

PARTICIPANTS

A random subsample of 743 persons aged 75 and older.

MEASUREMENTS

The well-being measures, assessed at baseline, 12 months, and 24 months, included a modified version of the Fall Efficacy Scale, Patient-Reported Outcomes Measurement Information System (PROMIS) anxiety and depression scales, and Late-Life Function and Disability Instrument.

RESULTS

Participants in the intervention (n = 384) and control groups (n = 359) were comparable in age: mean (standard deviation) of 81.9 (4.7) versus 81.8 (5.0) years. Mean scores were similar between groups at 12 and 24 months for concern about falling, physical function, and disability, whereas the intervention group's mean scores on anxiety and depression were .7 points lower (i.e., better) at 12 months and .6 to .8 points lower at 24 months. For each of these outcomes, differences between the groups' adjusted least square mean changes from baseline to 12 and 24 months, respectively, were quantitatively small. The overall difference in means between groups over 2 years was statistically significant only for depression, favoring the intervention: -1.19 (99% confidence interval, -2.36 to -.02), with 3.5 points representing a minimally important difference.

CONCLUSIONS

STRIDE's multifactorial intervention to reduce fall injuries was not associated with clinically meaningful improvements in patient well-being.

Standardised approach to measuring goal-based outcomes among older disabled adults: results from a multisite pilot

BACKGROUND

Older adults with complex care needs face trade-offs in determining the right course of treatment. The Centers for Medicare and Medicaid Services identified 'Care is personalized and aligned with patient's goals' as a key meaningful measures category, yet existing quality measures typically assess disease-specific care and may not effectively evaluate what is most important to older adults and family members. Measures based on individualised goals and goal-based outcomes have been proposed as an alternative but are not routinely assessed or implemented.

OBJECTIVES

We tested two approaches to assessing goal-based outcomes that allow individuals to set goals based on their own priorities and measure progress-(1) goal attainment scaling and (2) existing, validated patient-reported outcome measures (PROM).

METHODS

A prospective cohort study of feasibility in seven sites (33 clinicians) of the two approaches with 229 individuals. We calculated performance on a measure of achievement of individually identified goals.

RESULTS

Both approaches were successfully implemented in a non-randomly selected population, and a goal-based outcome could be calculated for 189 (82%) of participants. Most individuals met their goal-based outcome (73%) with no statistical difference between the goal attainment scaling approach (74%) and the patient-reported outcomes approach (70%). Goals were heterogeneous ranging from participating in activities, health management, independence and physical health. Clinicians chose to use goal attainment scaling (n=184, 80%) more often than PROMs (n=49, 20%) and rated the goal attainment scaling approach as useful for providing patient care.

CONCLUSION

Goal-based outcomes have the potential to both improve the way healthcare is provided and fill a critical gap in value-based payment.

D-CARE: The Dementia Care Study: Design of a Pragmatic Trial of the Effectiveness and Cost Effectiveness of Health System-Based Versus Community-Based Dementia Care Versus Usual Dementia Care

BACKGROUND/OBJECTIVES

Although several approaches have been developed to provide comprehensive care for persons living with dementia (PWD) and their family or friend caregivers, the relative effectiveness and cost effectiveness of community-based dementia care (CBDC) versus health system-based dementia care (CBDC) and the effectiveness of both approaches compared with usual care (UC) are unknown.

DESIGN

Pragmatic randomized three-arm superiority trial. The unit of randomization is the PWD/caregiver dyad.

SETTING

Four clinical trial sites (CTSs) based in academic and clinical health systems.

PARTICIPANTS

A total of 2,150 English- or Spanish-speaking PWD who are not receiving hospice or residing in a nursing home and their caregivers.

INTERVENTIONS

Eighteen months of (1) HSDC provided by a nurse practitioner or physician's assistant dementia care specialist who works within the health system, or (2) CBDC provided by a social worker or nurse care consultant who works at a community-based organization, or (3) UC with as needed referral to the Alzheimer's Association Helpline.

MEASUREMENTS

Primary outcomes: PWD behavioral symptoms and caregiver distress as measured by the Neuropsychiatric Inventory Questionnaire (NPI-Q) Severity and Modified Caregiver Strain Index scales.

SECONDARY OUTCOMES

NPI-Q Distress, caregiver unmet needs and confidence, and caregiver depressive symptoms. Tertiary outcomes: PWD long-term nursing home placement rates, caregiver-reported PWD functional status, cognition, goal attainment, "time spent at home," Dementia Burden Scale-Caregiver, a composite measure of clinical benefit, Quality of Life of persons with dementia, Positive Aspects of Caregiving, and cost effectiveness using intervention costs and Medicare claims.

RESULTS

The results will be reported in the spring of 2024.

CONCLUSION

D-CARE will address whether emphasis on clinical support and tighter integration with other medical services has greater benefit than emphasis on social support that is tied more closely to community resources. It will also assess the effectiveness of both interventions compared with UC and will evaluate the cost effectiveness of each intervention.

Dementia and Falls Management in Underserved Populations: The Cognition and Mobility Care Management Program

BACKGROUND/OBJECTIVES

Cognitive and mobility impairments are common and underdiagnosed chronic conditions that afflict community-dwelling older adults. This study describes the organization, implementation, and evaluation of an intervention for underserved and ethnically diverse older patients with dementia and/or falls risk.

DESIGN

Observation, baseline and 1 year after intervention.

SETTING

Community-based primary care county clinics in inland southern California.

PARTICIPANTS

A total of 272 persons, aged 70 years and older, who screened positive for falls and/or dementia and enrolled in the Cognition and Mobility Care Management program during the study period.

INTERVENTION

A nurse care manager performed a patient and caregiver evaluation and created and implemented a care plan with medical, behavioral, and psychosocial interventions in partnership with patients and their primary care providers.

MEASUREMENTS

Process outcomes included rates of positive screening for dementia and fall risk, referral, enrollment, and visit completion. Patient outcomes included fall history, mobility and cognitive assessments, and depression scales. Patients and/or caregivers completed questionnaires rating perceived benefits of enrollment after 1 year in the program.

RESULTS

Medical assistants screened 573 patients aged 70 years and older during the study period; 78% screened positive for dementia and/or fall risk. Of the patients who screened positive, 94% were referred; 91% of contacted patients elected to enroll, and 272 patients completed an intake visit (mean_age = 77 years; 65% female; 75% Latino; 10% African American). The patients and caregivers who completed satisfaction questionnaires 1 year after enrollment rated the program highly, and 92% would recommend the program to others.

CONCLUSION

A primary care-based screening and comanagement program to identify and manage dementia and falls risk in primarily Latino and African American older adult patients living in an underserved area was well received, with high satisfaction and perceived benefit from patients and caregivers.

Refining a Taxonomy of Goals for Older Adults With Functional Limitations and Their Caregivers to Inform Care Planning

Purpose: The purpose of the study is to capture goals expressed by older adults with functional limitations and their caregivers. Methods: Through focus groups and interviews, 76 older adults with ≥1 activity of daily living limitation and 28 family/friend caregivers were asked about what mattered most to them and their goals for care. Transcripts were coded using an existing taxonomy. Goals that did not fit the taxonomy were assigned new codes. Results: We identified more than 50 goals in eight domains. Domains included (a) Medical Care; (b) Quality of Life: Physical; (c) Quality of Life: Social and Emotional; (d) Access to Services and Supports; (e) Caregiver Needs and Concerns; (f) End of Life; (g) Independence; and (h) Acceptable Housing. Conclusion: While there is overlap between identified goals and the existing taxonomy, new goals emerged. The goal domains identified could serve as a framework to improve and measure the quality of goal-oriented care for older adults with complex needs.

A Randomized Trial of a Multifactorial Strategy to Prevent Serious Fall Injuries

BACKGROUND

Injuries from falls are major contributors to complications and death in older adults. Despite evidence from efficacy trials that many falls can be prevented, rates of falls resulting in injury have not declined.

METHODS

We conducted a pragmatic, cluster-randomized trial to evaluate the effectiveness of a multifactorial intervention that included risk assessment and individualized plans, administered by specially trained nurses, to prevent fall injuries. A total of 86 primary care practices across 10 health care systems were randomly assigned to the intervention or to enhanced usual care (the control) (43 practices each). The participants were community-dwelling adults, 70 years of age or older, who were at increased risk for fall injuries. The primary outcome, assessed in a time-to-event analysis, was the first serious fall injury, adjudicated with the use of participant report, electronic health records, and claims data. We hypothesized that the event rate would be lower by 20% in the intervention group than in the control group.

RESULTS

The demographic and baseline characteristics of the participants were similar in the intervention group (2802 participants) and the control group (2649 participants); the mean age was 80 years, and 62.0% of the participants were women. The rate of a first adjudicated serious fall injury did not differ significantly between the groups, as assessed in a time-to-first-event analysis (events per 100 person-years of follow-up, 4.9 in the intervention group and 5.3 in the control group; hazard ratio, 0.92; 95% confidence interval [CI], 0.80 to 1.06; P = 0.25). The rate of a first participant-reported fall injury was 25.6 events per 100 person-years of follow-up in the intervention group and 28.6 events per 100 person-years of follow-up in the control group (hazard ratio, 0.90; 95% CI, 0.83 to 0.99; P = 0.004). The rates of hospitalization or death were similar in the two groups.

CONCLUSIONS

A multifactorial intervention, administered by nurses, did not result in a significantly lower rate of a first adjudicated serious fall injury than enhanced usual care. (Funded by the Patient-Centered Outcomes Research Institute and others; STRIDE ClinicalTrials.gov number, NCT02475850.).

Transforming Dementia Care Through Pragmatic Clinical Trials Embedded in Learning Healthcare Systems

The current evidence base for testing nonpharmacological interventions for people living with dementia (PLWD) and their caregivers is limited, especially within care settings such as ambulatory care, assisted living communities, nursing homes, hospitals, and hospices. There has been even less attention to translation of effective interventions for PLWD into delivery of care. Thus, there is an urgent need for researchers to partner with these care settings, especially those that follow a learning healthcare systems (LHSs) model, and vice versa to conduct embedded pragmatic clinical trials (ePCTs). These trials are conducted within sites that offer routine care and are designed to answer important, relevant clinical questions and leverage existing electronic health and administrative data. ePCTs set in LHSs create a unique opportunity for researchers, healthcare providers, and PLWD and their families to work and learn together as potentially effective interventions are studied and stress tested in real-world situations. Healthcare settings that embrace research or quality improvement as part of a culture of continuous learning are ideal settings for ePCTs. In this article, we summarize what we have learned from the National Institutes of Health's Health Care Systems Research Collaboratory-funded ePCTs, discuss challenges of ePCTs within settings that serve PLWD, and describe the work of the Health Care Systems Core within the National Institute on Aging's IMbedded Alzheimer's Disease and Related Dementias Clinical Trials Collaboratory that will occur over the next 5 years.

Patient and Caregiver Benefit From a Comprehensive Dementia Care Program: 1-Year Results From the UCLA Alzheimer's and Dementia Care Program

BACKGROUND/OBJECTIVES

Persons with Alzheimer disease and related dementias (ADRDs) require comprehensive care that spans health systems and community-based organizations. This study examined the clinical outcomes of a comprehensive dementia care program and identified subgroups who were more likely to benefit.

DESIGN

Observational, baseline and 1 year after intervention.

SETTING

Urban, academic medical center.

PARTICIPANTS

A total of 554 persons with dementia and their caregivers who had 1-year follow-up evaluations and data on clinical outcomes.

INTERVENTION

Health system-based comprehensive dementia care management program using nurse practitioner dementia care managers.

MEASUREMENTS

Patient measures included the Mini-Mental State Examination (MMSE), the Functional Activities Questionnaire, Basic and Instrumental Activities of Daily Living scales, the Cornell Scale for Depression in Dementia, and the Neuropsychiatric Inventory Questionnaire (NPI-Q) Severity. Caregiver measures included the Modified Caregiver Strain Index, the Patient Health Questionnaire-9, NPI-Q Distress, and the Dementia Burden Scale-Caregiver). We used established minimal clinically important differences and lowest tertiles of baseline symptoms to define improving symptoms and maintaining low symptoms as clinical benefit for patients and caregivers.

RESULTS

At year 1, persons with ADRD improved on all scales, except MMSE and functional status measures; caregivers improved on all scales. Using validated instruments, 314/543 (58%) of patients, 282/447 (63%) of caregivers, and 376/501 (75%) of patients or caregivers demonstrated clinical benefit. In adjusted multivariate models, at year 1, more behavioral symptoms and fewer depression symptoms at baseline were associated with patient improvement; and fewer baseline depression symptoms were associated with maintaining low behavioral symptoms. Male caregiver sex, higher baseline caregiver burden, and caring for patients with fewer baseline depression symptoms were associated with caregiver improvement. Male caregiver sex and patients with fewer depression symptoms, fewer behavioral symptoms, and more functional impairment at baseline were associated with caregivers maintaining low burden at 1 year.

CONCLUSIONS

Health system-based comprehensive dementia care management is a promising approach to improving clinical outcomes, with benefits for both patients and caregivers. J Am Geriatr Soc 67:2267-2273, 2019.

Putting Goal-Oriented Patient Care Into Practice

New efforts have begun to transform healthcare to focus on patient-centered care. Such efforts will be facilitated by eliciting, operationalizing, and measuring the attainment of patient-identified goals of healthcare. This article describes a practical approach to goal setting and measurement that can be used in efforts to implement patient-centered care.

The Effect of a Comprehensive Dementia Care Management Program on End-of-Life Care

BACKGROUND/OBJECTIVES

Although Alzheimer disease and other dementias are life limiting, only a minority of these patients or their proxy decision makers participate in advance care planning. We describe end-of-life care preferences and acute care and hospice use in the last 6 months of life for persons enrolled in a comprehensive dementia care management program.

DESIGN

Observational, retrospective cohort.

SETTING

Urban, academic medical center.

PARTICIPANTS

A total of 322 persons enrolled in dementia care management after July 1, 2012, who died before July 1, 2016.

INTERVENTION

Dementia care comanagement model using nurse practitioners partnered with primary care providers and community organizations to provide comprehensive dementia care, including advance care planning.

MEASUREMENTS

Advance care preferences, use of Physician Orders for Life Sustaining Treatment (POLST), hospice enrollment, and hospitalizations and emergency department (ED) visits in the last 6 months of life obtained from electronic health record data.

RESULTS

Nearly all decedents (99.7%, N = 321) had a goals-of-care conversation documented (median = 3 conversations; interquartile range = 2-4 conversations), and 64% had advance care preferences recorded. Among those with recorded preferences, 88% indicated do not resuscitate, 48% limited medical interventions, and 35% chose comfort-focused care. Most patients (89%) specified limited artificial nutrition, including withholding feeding tubes. Over half (54%) had no hospitalizations or ED visits in the last 6 months of life, and intensive care unit stays were rare (5% of decedents). Overall, 69% died on hospice. Decedents who had completed a POLST were more likely to die in hospice care (74% vs 62%; P = .03) and die at home (70% vs 59%; P = .04).

CONCLUSIONS

Enrollees in a comprehensive dementia care comanagement program had high engagement in advance care planning, high rates of hospice use, and low acute care utilization near the end of life. Wider implementation of such programs may improve end-of-life care for persons with dementia. J Am Geriatr Soc 67:443-448, 2019.

Health Care Utilization and Cost Outcomes of a Comprehensive Dementia Care Program for Medicare Beneficiaries

IMPORTANCE

An estimated 4 to 5 million Americans have Alzheimer disease or another dementia.

OBJECTIVE

To determine the health care utilization and cost outcomes of a comprehensive dementia care program for Medicare fee-for-service beneficiaries.

DESIGN, SETTING, AND PARTICIPANTS

In this case-control study, we used a quasiexperimental design to compare health care utilization and costs for 1083 Medicare fee-for-service beneficiaries enrolled in the University of California Los Angeles Health System Alzheimer and Dementia Care program between July 1, 2012, and December 31, 2015, with those of 2166 similar patients with dementia not participating in the program. Patients in the comparison cohort were selected using the zip code of residence as a sampling frame and matched with propensity scores, which included demographic characteristics, comorbidities, and prior-year health care utilization. We used Medicare claims data to compare utilization and cost outcomes for the 2 groups.

INTERVENTIONS

Patients in the dementia care program were comanaged by nurse practitioners and physicians, and the program consisted of structured needs assessments of patients and their caregivers, creation and implementation of individualized dementia care plans with input from primary care physicians, monitoring and revising care plans, referral to community organizations for dementia-related services and support, and access to a clinician for assistance and advice 24 hours per day, 7 days per week.

MAIN OUTCOMES AND MEASURES

Admissions to long-term care facilities; average difference-in-differences per quarter over the 3-year intervention period for all-cause hospitalization, emergency department visits, 30-day hospital readmissions, and total Medicare Parts A and B costs of care. Program costs were included in the cost estimates.

RESULTS

Program participants (n = 382 men, n = 701 women; mean [SD] age, 82.10 [7.90] years; age range 54-101 years) were less likely to be admitted to a long-term care facility (hazard ratio, 0.60; 95% CI, 0.59-0.61) than those not participating in the dementia care program (n = 759 men, n = 1407 women; mean [SD] age, 82.42 [8.50] years; age range, 34-103 years). There were no differences between groups in terms of hospitalizations, emergency department visits, or 30-day readmissions. The total cost of care to Medicare, excluding program costs, was $601 less per patient per quarter (95% CI, -$1198 to -$5). After accounting for the estimated program costs of $317 per patient per quarter, the program was cost neutral for Medicare, with an estimated net cost of -$284 (95% CI, -$881 to $312) per program participant per quarter.

CONCLUSIONS AND RELEVANCE

Comprehensive dementia care may reduce the number of admissions to long-term care facilities, and depending on program costs, may be cost neutral or cost saving. Wider implementation of such programs may help people with dementia stay in their communities.

Personalized Goal Attainment in Dementia Care: Measuring What Persons with Dementia and Their Caregivers Want

OBJECTIVES

To develop a process of goal-setting and measurement of goal attainment in a dementia care management program.

DESIGN

Observational.

SETTING

Dementia care management program in an urban academic medical center.

PARTICIPANTS

Persons with dementia (N=101) and their caregivers; nurse practitioner dementia care managers (N=5).

INTERVENTION

Specification of a personalized health goal and action plan and measurement of goal attainment using goal attainment scaling in a clinical care visit.

MEASUREMENTS

Goal attainment at 6 and 12 months; focus groups of 5 dementia care managers.

RESULTS

Eighty-four percent of participant goals were nonmedical, 47% were related to quality of life, and 29% were caregiver support goals. Eighty-eight percent of participants felt that the goal they set was meaningful and 74% that the goal-setting process captured something different from usual care, and 85% found the process helpful in planning for future care. At 6 months, 74% of dyads had achieved or exceeded their expected level of goal attainment. Dementia care managers felt that the goal-setting process improved their understanding of what was most important to the patient, helped set expectations about disease progression and care needs, and provided positive reinforcement when goals were accomplished and an opportunity for revision when goals were not met.

CONCLUSION

Goal setting using goal attainment scaling can be incorporated into the care of persons with dementia to establish and attain person-centered goals. Research is needed to further develop personalized goal attainment as an outcome measure for dementia care. J Am Geriatr Soc 66:2120-2127, 2018.

Screening, Recruitment, and Baseline Characteristics for the Strategies to Reduce Injuries and Develop Confidence in Elders (STRIDE) Study

Background

We describe the recruitment of participants for Strategies to Reduce Injuries and Develop Confidence in Elders (STRIDE), a large pragmatic cluster randomized trial that is testing the effectiveness of a multifactorial intervention to prevent serious fall injuries. Eligible persons were 70 years or older, community-living, and at increased risk for serious fall injuries. The modified goal was to recruit 5,322 participants over 20 months from 86 primary care practices within 10 diverse health care systems across the United States.

Methods

The at-risk population was identified using two distinct but complementary screening strategies that included three questions administered centrally via the mail (nine sites) or in the clinic (one site), while recruitment was completed centrally by staff at Yale.

Results

For central screening, 226,603 letters mailed to 135,118 patients yielded 28,719 positive screens (12.7% of those mailed and 46.5% of the 61,729 returned). In the clinic, 22,537 screens were completed, leading to 5,732 positive screens (25.4%). Of the 34,451 patients who screened positive for high risk of serious fall injuries, 31,872 were sent a recruitment packet and, of these, 5,451 (17.1%) were enrolled over 20 months (mean age: 80 years; 62% female). The participation rate was 34.0% among eligible patients. The enrollment yields were 3.6% (vs 5% projected) for each patient screened centrally, despite multiple screens, and 10.5% (vs 33.9% projected) for each positive clinic screen.

Conclusions

Despite lower-than-expected yields, the STRIDE Study exceeded its modified recruitment goal. If the STRIDE intervention is found to be effective, the two distinct strategies for identifying a high-risk population of older persons could be implemented by most health care systems.

A Composite Measure of Caregiver Burden in Dementia: The Dementia Burden Scale-Caregiver

OBJECTIVES

To better capture the scope of caregiver burden by creating a composite of 3 existing measures that assess different health domains.

DESIGN

Prospective follow-up study.

SETTING

University-based dementia care management program.

PARTICIPANTS

Caregivers of persons with dementia (PWD) (N=1,091).

MEASUREMENTS

The composite measure (the Dementia Burden Scale-Caregiver (DBS-CG)) was based on the Modified Caregiver Strain Index, Neuropsychiatric Inventory Questionnaire Distress Scale, and Patient Health Questionnaire (PHQ-9). Alternative factor structures were evaluated using 2 confirmatory factor analysis (CFA) models: a bifactor model and a 3 correlated factors model. Good model fit was defined as a root mean square error of approximation (RMSEA) of less than 0.06 and comparative fit index (CFI) value greater than 0.95. Coefficient omega was used to estimate scale reliability. Minimally important differences (MIDs) were estimated by anchoring the magnitude of DBS-CG change to change in caregiver self-efficacy and functional ability of PWD.

RESULTS

The bifactor CFA model fit best (RMSEA = 0.04, CFI = 0.95). Based on this model, a DBS-CG scale was created wherein all items were transformed to a possible range of 0 to 100 and then averaged. Higher scores indicate higher burden. Mean DBS-CG score was 27.3. The reliability was excellent (coefficient omega=0.93). MID estimates ranged from 4 to 5 points (effect sizes: 0.20-0.49).

CONCLUSION

This study provides support for the reliability and validity of the DBS-CG. It can be used as an outcome measure to assess the effect of interventions to reduce dementia caregiver burden.
