Elevated Amyloid-ß PET Scan and Cognitive and Functional Decline in Mild Cognitive Impairment and Dementia of Uncertain Etiology.

BACKGROUND: Elevated amyloid-ß (Aß) on positron emission tomography (PET) scan is used to aid diagnosis of Alzheimer's disease (AD), but many prior studies have focused on patients with a typical AD phenotype such as amnestic mild cognitive impairment (MCI). Little is known about whether elevated Aß on PET scan predicts rate of cognitive and functional decline among those with MCI or dementia that is clinically less typical of early AD, thus leading to etiologic uncertainty. OBJECTIVE: We aimed to investigate whether elevated Aß on PET scan predicts cognitive and functional decline over an 18-month period in those with MCI or dementia of uncertain etiology. METHODS: In 1,028 individuals with MCI or dementia of uncertain etiology, we evaluated the association between elevated Aß on PET scan and change on a telephone cognitive status measure administered to the participant and change in everyday function as reported by their care partner. RESULTS: Individuals with either MCI or dementia and elevated Aß (66.6% of the sample) showed greater cognitive decline compared to those without elevated Aß on PET scan, whose cognition was relatively stable over 18 months. Those with either MCI or dementia and elevated Aß were also reported to have greater functional decline compared to those without elevated Aß, even though the latter group showed significant care partner-reported functional decline over time. CONCLUSIONS: Elevated Aß on PET scan can be helpful in predicting rates of both cognitive and functional decline, even among cognitively impaired individuals with atypical presentations of AD.

Amyloid-ß PET Scan Results Disclosure and Care-Partner Emotional Well-Being Over Time.

BACKGROUND: Diagnostic tests, such as amyloid-ß positron emission tomography (PET) scans, can increase appropriate therapeutic management for the underlying causes of cognitive decline. To evaluate the full utility of this diagnostic tool, information is needed on whether results from amyloid-ß PET scans influence care-partner outcomes. OBJECTIVE: This study examines the extent to which previous disclosure of elevated amyloid (suggestive of Alzheimer's disease (AD) etiology) versus not-elevated amyloid (not suggestive of AD etiology) is associated with changes in care-partner wellbeing. METHODS: The study used data derived from a national longitudinal survey of Medicare beneficiaries (n = 921) with mild cognitive impairment (MCI) or dementia and their care-partners. Care-partner wellbeing outcomes included depressive symptoms (PHQ-8), subjective burden (4-item Zarit burden score), and a 3-item measure of loneliness. Change was measured between 4 (Time 1) and 18 (Time 2) months after receiving the scan results. Adjusted linear regression models regressed change (Time 2-Time 1) in each outcome on scan result. RESULTS: Care-partners were primarily white, non-Hispanic, college-educated, and married to the care recipient. Elevated amyloid was not associated with statistically significant Time 1 differences in outcomes or with statistically significant changes in depressive symptoms 0.22 (-0.18, 0.61), subjective burden 0.36 (-0.01, 0.73), or loneliness 0.15 (-0.01, 0.32) for care-partners from one time point to another. CONCLUSION: Given advances in AD biomarker testing, future research in more diverse samples is needed to understand the influence of scan results on care-partner wellbeing across populations.

How can equitable video visit access be delivered in primary care? A qualitative study among rural primary care teams and patients.

OBJECTIVE: The COVID-19 pandemic sparked exponential growth in video visit use in primary care. The rapid shift to virtual from in-person care exacerbated digital access disparities across racial groups and rural populations. Moving forward, it is critical to understand when and how to incorporate video visits equitably into primary care. We sought to develop a novel clinical algorithm to guide primary care clinics on how and when to employ video visits as part of care delivery. DESIGN: Qualitative data collection: one team member conducted all patient semistructured interviews and led all focus groups with four other team members taking notes during groups. SETTING: 3 rural primary care clinics in the USA. PARTICIPANTS: 24 black veterans living in rural areas and three primary care teams caring for black veterans living in rural areas. PRIMARY AND SECONDARY OUTCOME MEASURES: Findings from semistructured interviews with patients and focus groups with primary care teams. RESULTS: Key issues around appropriate use of video visits for clinical teams included having adequate technical support, encouraging engagement during video visits and using video visits for appropriate clinical situations. Patients reported challenges with broadband access, inadequate equipment, concerns about the quality of video care, the importance of visit modality choice, and preferences for in-person care experience over virtual care. We developed an algorithm that requires input from both patients and their care team to assess fit for each clinical encounter. CONCLUSIONS: Informed matching of patients and clinical situations to the right visit modality, along with individual patient technology support could reduce virtual access disparities.

Psychological distress among medically complex veterans with a recent emergency department visit.

Medical complexity and psychological distress are associated with frequent emergency department (ED) use. Despite this known association, our understanding is limited about which patients are at risk for persistent psychological distress and what patterns of distress emerge over time. A secondary data analysis was used to examine self-reported psychological distress (defined as ≥14 unhealthy days due to poor mental health in the past month) at 30 and 180 days following enrollment in a randomized control trial of 513 medically complex Veterans after a nonpsychiatric ED visit. We used a multivariable ordered logistic regression model to examine the association of a priori factors [baseline psychological distress, age, race, income, health literacy, deficits in activities of daily living (ADL), and deficits in instrumental activities of daily living] with three psychological distress classifications (no/low, intermittent, and persistent). Among 513 Veterans, 40% reported at baseline that they had experienced high psychological distress in the previous month. Older age was associated with lower odds of high psychological distress (OR = 0.95; 95% CI: 0.94-0.97). Baseline factors associated with significantly higher odds of persistent psychological distress at 30 and 180 days assessments, included having the inadequate income (OR = 1.61; 95% CI: 1.02-2.55), having low health literacy (OR = 1.63; 95% CI: 1.01-2.62), and reporting at least one ADL deficit (OR = 1.94; 95% CI: 1.13-3.33). Psychological distress at follow-up was common among medically complex Veterans with a recent ED visit. Future research should explore interventions that integrate distress information into treatment plans and/or link to mental health referral services.

Family Caregiver and Provider Perspectives on Inclusive Care: Aligning Needs and Expectations.

BACKGROUND: Home-based and community-based health care for individuals with complex medical conditions is often provided by family caregivers. Yet caregivers often are not meaningfully included in interactions with clinical health care teams. Inclusive care means inviting the caregiver to participate in shared decision-making and treatment planning. For aging or medically vulnerable adults, caregiver inclusion is an important facet of patient-centered care. METHODS: We apply a mixed-methods approach using a survey (n=50) and semistructured interview data (n=13) from a national sample of caregivers of veterans and semistructured interview data from (n=24) providers from 3 Veterans Affairs regional networks. We elicited data from caregivers about their experiences with inclusive care and how providers communicate with them and assess their capacity. We juxtaposed these data with provider perspectives to see where there was alignment. FINDINGS: We determined that caregivers play important roles in trust-building, communications management, implementation of care plans at home or in the community, and improving the care of care recipients-while maintaining a balance between competing tensions. CONCLUSIONS: Our findings suggest that expanding inclusive care could improve care quality and health outcomes of individuals with complex health care needs. Further, our findings bolster recent policy efforts at the federal and state levels to increase recognition of caregivers as key members of the health care team.

Including Family Caregivers In Seriously Ill Veterans' Care: A Mixed-Methods Study.

Family caregivers often serve as unpaid members of the home and community-based care workforce for people with serious illness; as key partners in the home-clinic continuum, they should be included in health care teams. The Campaign for Inclusive Care is an initiative within the Veterans Affairs health care system to improve provider practices for including caregivers of military members in treatment planning and decisions. We defined inclusive care using a literature review, provider interviews, and a caregiver survey. We found that inclusive care involves clear definition of the caregiver role, system policies for inclusion, assessment of caregivers' capacity, explicit involvement of caregivers, and mutuality in caregiver-provider communication. We recommend solutions based on this definition that can inform development of a national caregiver strategy, required of the Department of Health and Human Services by the Recognize, Assist, Include, Support, and Engage Family Caregivers Act of 2018.

Interventions That Support or Involve Caregivers or Families of Patients with Traumatic Injury: a Systematic Review.

BACKGROUND: Almost 40 million family caregivers care for a loved one with severe physical or cognitive impairments. The purpose of this review is to summarize evidence about the benefits of interventions to support or involve family members/caregivers of patients with trauma-related injury on caregiver, patient, and household outcomes. METHODS: English-language peer-reviewed publications in MEDLINE, CINAHL, and PsycINFO from 1995 through December 2016 were identified. Eligible studies included RCT or quasi-experimental studies evaluating interventions designed to support or involve caregivers or family members of patients with TBI, PTSD, or polytrauma. Abstractions were completed by one reviewer and checked by a second; two reviewers independently assessed risk of bias using the Cochrane Effective Practice and Organization of Care Review Criteria. RESULTS: Thirteen studies (n = 9 TBI; n = 4 PTSD, n = 0 polytrauma) evaluated psychological or rehabilitation interventions involving caregivers. Interventions did not improve TBI patients' functional status (standardized mean difference [SMD], 0.29 [95% confidence interval [CI], - 0.51 to 1.08]) or psychological symptoms (SMD - 0.25, CI - 0.62 to 0.12). Qualitative analysis shows potential intervention benefit for TBI symptoms. Interventions did not improve TBI caregiver psychological symptoms (SMD - 0.26, CI - 0.57 to 0.05); however, qualitative analysis suggests mixed effects for caregiver burden and quality of life. Positive intervention effects on patients' PTSD symptoms, mental health service use, and PTSD caregivers' psychological symptoms were identified with certain interventions. Strength of evidence ranged from moderate to very low. DISCUSSION: Studies showed mixed patterns of intervention effects on caregiver and patient outcomes; evidence about intervention impact is inconclusive. This review is the first to identify caregiving interventions for patients with TBI and polytrauma and extends past reviews about patients with PTSD. Limitations include a small evidence base, low study quality, disparate methods, varied outcome measures, and high heterogeneity. PROSPERO Registration CRD42017053516.
