AbstractBackgroundPeople living with dementia have high rates of emergency department (ED) use and hospitalizations. Identifying factors that influence acute care utilization is important. We examined the influence of physical activity levels on risk of hospitalization and emergency department (ED) use in a population of older people living with mild cognitive impairment (MCI) or dementia.MethodsWe included people with a diagnosis of MCI or dementia followed in Community Internal Medicine at Mayo Clinic, age 55 years and older, who had a clinic visit between June 1, 2019 and June 30, 2021 and had completed a social determinants of health questionnaire about physical activity levels. Physical activity was classified based on responses to questions about time spent exercising per week and rated as sufficiently active (≥150 minutes per week), insufficiently active (10‐140 minutes) or physically inactive (0 minutes). The risk of hospitalization and ED visits across physical activity levels was examined using quasi‐Poisson regression and presented as rate ratios (95% confidence interval (CI)), with adjustment for demographics, Charlson Comorbidity Index, marital status, living arrangement and body mass index.ResultsA total of 3090 persons living with MCI (n = 1308) or dementia (n = 1782) were included. People who were physically inactive were more likely to be older, female, not married, obese, have higher comorbid burden and a dementia diagnosis (p<0.001). Hospitalization and ED visit rates in those who were physically inactive were approximately double the rates for the sufficiently active group (p<0.001). Compared with those who were sufficiently active, people who were physically inactive had a significantly higher risk of hospitalization (rate ratio 1.73, 95% CI 1.30‐2.31) and ED visits (rate ratio 1.59, 95% CI 1.26‐2.01).ConclusionsPhysical inactivity in older people living with MCI or dementia is associated with an increased risk of ED visits and hospitalization. Targeted physical activity interventions could potentially impact on acute care utilization in this population. Our findings emphasize an area for public health promotion in people living with MCI or dementia.

Abstract Few studies have reliable estimates on costs of informal care following hospitalization, including health care use and out-of-pocket costs for family caregivers (FCGs) and their care recipients (CR). This presentation discusses results from a Transitional Palliative Care (TPC) intervention on healthcare use and out-of-pocket spending for both FCGs and CRs. The study used data from the Technology-Enhanced TPC study, a trial comparing the TPC intervention to support FCGs of seriously ill CRs to an attention control condition. TPC FCGs received teaching, guidance, and counseling via video calls for 8 weeks following CR hospital discharge. After discharge, a research assistant called FCGs once a month for up to 6 months or CR death to collect healthcare utilization (e.g. outpatient, emergency department, and hospital), out-of-pocket healthcare spending (e.g. deductibles and coinsurance), and health-related travel costs (e.g., transportation, lodging, food) for FCGs and CRs. Incidence rate ratios (IRR) were estimated using negative binomial regressions. The study included 282 FCG-CR dyads across 3 US states. TPC reduced nights in the hospital for CR (IRR = 0.75; 95% CI = 0.56 – 0. 99). Total out-of-pocket spending was not significantly different for TPC versus control; however, TPC dyads reported lower lodging costs (IRR = 0.71; 95% CI = 0.56-0.89). Across groups, mean out-of-pocket spending for dyads was $1401.85, with healthcare payments contributing $1048.58 and transportation expenses contributing $136.79. This study contributes to evidence that palliative care interventions reduce unnecessary hospitalization for seriously ill patients, yet the financial costs to caregivers remain high.

Abstract Recruiting family caregivers to participate in research, especially caregivers of people with severe or life limiting illnesses transitioning from hospital to home, is challenging. Traditional approaches for recruitment, including recruitment done on site at clinics or hospitals, became impracticable during the COVID-19 pandemic, leading to shifts toward virtual or remote recruitment and consent. In this presentation, Dr. Gustavson will compare the success of these two methodological approaches, in-person and remote recruitment and consent, used in the Technology-Enhanced Transitional Palliative Care (TPC) study. She found that the rate of recruitment and consent done in-person was 28% and the rate of remote recruitment and consent was 23%. Those recruited and consented remotely were more likely to be younger, white, have greater than high school education, and were children of or had another non-spousal relationship to the care recipient. She discusses the limitations and benefits of each recruitment modality, including the impact on representativeness of the study sample.

Abstract In the research literature and amongst grant reviewers, there are persistent questions about whether internet connectivity challenges, especially in rural populations, will limit the potential for virtual or decentralized clinical trials to improve participation of underrepresented groups. In clinical practice, e-health and telehealth advancements have been touted as potential models of care to address health disparities associated with access to care, but without reliable internet connectivity, these disparities may perpetuate or even widen. In this presentation Dr. Holland examines the prevalence of connectivity problems during the Technology-Enhanced Transitional Palliative Care (TPC) study, a virtual clinical trial across three Midwestern states, and provides guidance on the challenges faced. Data are from structured notes from nurse interventionists who documented any connectivity issues in the study’s electronic health record. Of the 1003 visits reviewed, only 11% of visits (115/1003) contained a documented problem with internet connectivity. None of the participants withdrew from the trial due to problems with their internet connections. The findings support the effective use of virtual visits in research involving participants living in rural locations. Virtual randomized controlled trials provide a strategy that enables participation for rural individuals who may not otherwise have access to clinical trials conducted in-person in urban settings. Utilizing internet access to connect with and support people who live in rural areas is critically needed to advance clinical research.

Abstract In this presentation, Dr. Griffin will describe the Technology-Enhanced Transitional Palliative Care (TPC) study, a randomized controlled trial testing the efficacy and cost-effectiveness of an intervention to address FCGs’ unmet needs in order to improve their health and well-being. Nurse interventionists use video visits to teach, guide and counsel FCGs in rural areas caring for someone receiving palliative care and transitioning form hospital to home. In addition to providing background on the importance of addressing unmet family caregiver needs during care transitions for patients receiving palliative care, she will describe the study design, sample, intervention and control group procedures, including the use of video visits, and outcomes assessed. This presentation will provide necessary context for the remaining presentations.

Abstract Estimates of patient care costs often overlook the economic value of unpaid caregiving. This study aims to quantify the economic value of unpaid caregiving by rural FCGs. Using data from a multi-site randomized controlled trial evaluating Transitional Palliative Care (TPC) intervention for FCGs, this study quantifies the economic value of family caregiving in the six months following seriously ill care recipients’ hospital discharge using three valuation methods. Caregiving hours were self-reported by FCGs. The proxy cost approach assigned value to FCG hours using the national median home health aide wage. The unadjusted opportunity cost approach assigned value using the national median wage, by sex and education level. The adjusted opportunity cost approach assigned value by work force participation, using opportunity cost if employed and proxy cost otherwise. Of 282 FCGs, 94% were non-Hispanic White, 71% had a college degree, 56% were spouses, and 51% were in the workforce. FCG cost did not differ by treatment arm. FCGs of decedents compared to survivors reported significantly more hours per person-month (392 vs. 272, p&lt; 0.001), resulting in higher median opportunity cost ($12,653 vs. $8,843, p&lt; 0.001), proxy cost ($5,689 vs. $3,955, p&lt; 0.001), and adjusted opportunity cost ($9,490 vs. $6,443, p&lt; 0.001) per person-month. Proxy cost may undervalue FCG time, while opportunity cost may perpetuate labor market inequities. Policymakers must weigh trade-offs of different valuation methods. The high intensity of unpaid post-acute care, especially end-of-life, should be considered when designing policies and interventions to support unpaid FCG due to the economic impact on FCGs and employers.

People living with dementia have high rates of hospitalizations. Identifying factors that influence hospitalization is important. This study examines the influence of physical activity levels on risk of hospitalization and emergency department (ED) use among older people living with mild cognitive impairment (MCI) or dementia followed in our primary care practice in Rochester, Minnesota, United States. We included those age 55 years and older, who had a clinic visit between June 1, 2019 and June 30, 2021 and completed a social determinants of health questionnaire about physical activity levels ( n = 3090). Physical activity was classified as sufficiently active, insufficiently active, or physically inactive. Risk of hospitalization and ED visits by physical activity levels were examined. People who were physically inactive were at higher risk of hospitalization and ED visits ( p < .001) compared with those who were sufficiently active. This highlights an area for health promotion in people living with MCI and dementia.

Abstract Background and Objectives Social isolation is commonly experienced by older people and is associated with adverse health outcomes. Little is known about the influence of social isolation on the risk of acute care utilization among people living with mild cognitive impairment (MCI) or dementia. Our objective was to investigate the impact of social isolation on the risk of death, hospitalization, and emergency department (ED) use among people living with MCI or dementia who are followed in our Community Internal Medicine practice at Mayo Clinic, Rochester, Minnesota. Research Design and Methods We included people living with MCI or dementia, 55 years and older, who had a clinic visit between June 1, 2019, and June 30, 2021, and who had completed questions about social connections. The risk of death, hospitalization, and ED use was examined by levels of social connection (socially isolated, moderately isolated, moderately integrated, or socially integrated). Results Of 2,320 people included (1,010 with MCI and 1,310 with dementia), 455 (19.6%) were classified as socially isolated and 591 (25.5%) were moderately isolated. Compared with those who were socially integrated, people who were socially isolated were at higher risk of death, hospitalization, and ED visits (p &lt; .001). Discussion and Implications Social isolation is associated with an increased risk of acute health care utilization and death in people living with MCI or dementia. Interventions to address social isolation in this population are needed.
