Family structure, “Kinlessness”, and cognitive decline
Risk of mental health conditions in bereavement
Background: Caregiving to lung cancer patients is distressing, isolating, and associated with a high burden of anxiety and depression. However, few population-based studies in the U.S. have examined the risk of mental health conditions (MHCs) among spouses of lung cancer patients after the death of their partner. Guided by Anderson's Behavioral Health Utilization model, we examined the role of sex, pre-bereavement MHC, and decedents' healthcare u…
Together, but Isolated
ObjectivesSocial isolation has negative health implications for older adults and caregivers. We examine the interdependency of social isolation among community-dwelling Medicare beneficiaries and their primary caregivers.MethodsUsing data from the National Study of Caregiving and the National Health and Aging Trends Study (2015-2017, N = 522 dyads), we conducted actor-partner interdependence models to examine the dyadic associations between basel…
The Epidemiology of Social Isolation and Loneliness Among Family and Unpaid Caregivers of Older Adults
Objectives Older adults and their family and unpaid caregivers are at risk of social isolation and loneliness, leading to adverse health outcomes. We investigated the prevalence and correlates of social isolation and loneliness among caregivers of older Medicare beneficiaries. Methods Our sample included 2,174 caregivers from the National Study of Caregiving IV Round 12 linked with the National Health and Aging Trends Study Round 12, representing…
Defining and Validating Criteria to Identify Populations Who May Benefit From Home-Based Primary Care
BACKGROUND: Home-based primary care (HBPC) is an important care delivery model for high-need older adults. Currently, target patient populations vary across HBPC programs, hindering expansion and large-scale evaluation. OBJECTIVES: Develop and validate criteria that identify appropriate HBPC target populations. RESEARCH DESIGN: A modified Delphi process was used to achieve expert consensus on criteria for identifying HBPC target populations. All …
Trajectories of caregiving activities for aging parents
Adult children and partners provide essential care for aging populations in the US. Using group-based trajectory modelling, we examine trajectories of personal, chore, and financial care for aging parents and in-laws among n = 9,283 US households and associated household characteristics. We identify two distinct groups of caregiving trajectories: the “hands-on care dominant” group (75 percent) and the “high financial/increasing hands-on care” gro…
Mortality risk following end-of-life caregiving
Family caregiver roles and challenges in assisting patients with cancer treatment decision‐making
Background We aimed to describe the roles and challenges of family caregivers involved in patients' cancer treatment decision‐making. Methods Family caregiver‐reported data were analyzed from a national survey conducted in the United States by CancerCare® (2/2021–7/2021). Four select‐all‐that‐apply caregiver roles were explored: (1) observer (patient as primary decision‐maker); (2) primary decision‐maker; (3) shared decision‐maker with patient an…
Disparities and determinants of place of death
To better understand determinants and potential disparities in end of life, we model decedents' place of death with explanatory variables describing familial, social, and economic resources. A retrospective cohort of 204,041 decedents and their family members are drawn from the Utah Population Database family caregiving dataset. Using multinomial regression, we model place of death, categorized as at home, in a hospital, in another location, or u…
Effects of a Rehabilitation-at-Home Program Compared to Post-acute Skilled Nursing Facility Care on Safety, Readmission, and Community Dwelling Status
OBJECTIVES: To evaluate the effectiveness and safety of Rehabilitation-at-Home (RaH), which provides high-frequency, multidisciplinary post-acute rehabilitative services in patients' homes. DESIGN: Comparative effectiveness analysis. SETTING AND PARTICIPANTS: Medicare Fee-For-Service patients who received RaH in a Center for Medicare and Medicaid Innovation Center Demonstration during 2016-2017 (N=173) or who received Medicare Skilled Nursing Fac…
I Am the Home Care Agency”
As the locus of long-term care in the United States shifts from institutions to the community, paid caregivers (i.e., home health aides, personal care attendants) are providing more hands-on care to persons with dementia living at home. Yet, little is known about how family caregivers engage with paid caregivers. We conducted in-depth, semi-structured interviews ( n = 15) with family caregivers, of persons living at home with severe dementia, and…
Caring Together
Study findings highlight the importance of considering unique arrangements in dementia care. Receipt of paid care was not only determined by patient care needs. Creating equitable access to paid care may be a particularly important way to support both persons living with dementia and their family caregivers as care needs grow
Development and Validation of a Clinical Frailty Index for the World Trade Center General Responder Cohort
Objectives: To develop and validate a clinical frailty index to characterize aging among responders to the 9/11 World Trade Center (WTC) attacks. Methods: This study was conducted on health monitoring data on a sample of 6197 responders. A clinical frailty index, WTC FI-Clinical, was developed according to the cumulative deficit model of frailty. The validity of the resulting index was assessed using all-cause mortality as an endpoint. Its associ…
Assessing Health Care Use Trajectories After the Onset of Functional Disability
While activity limitations are a strong predictor of health care use among older adults, trajectories of health care use are heterogeneous. Along with clinical characteristics, potentially modifiable household and regional factors shaped health care trajectories, indicating that addressing these factors could potentially shift health care use patterns
Bivariate Spatial Pattern between Smoking Prevalence and Lung Cancer Screening in US Counties
Objectives: Lung cancer screening (LCS) with low-dose computed tomography (LDCT) has been a reimbursable preventive service covered by Medicare since 2015. Geographic disparities in the access to LDCT providers may contribute to the low uptake of LCS. We evaluated LDCT service availability for older adults in the United States (US) based on Medicare claims data and explored its ecological correlation with smoking prevalence. Materials and Methods…
Insufficient Advance Care Planning? Correlates of Planning Without Personal Conversations
Socially isolated persons are especially likely to do formal planning only, which is considered less effective than two-pronged ACP. Health care professionals should recognize that older adults with few kin may require additional support and guidance when doing ACP
Medicaid Contributes Substantial Costs to Dementia Care in an Ethnically Diverse Community
Results highlight Medicaid's contribution to covering the cost of dementia care in addition to Medicare. Studies that do not include Medicaid are unlikely to accurately reflect the true cost of dementia
Home but still engaged
This information can be useful in designing community programs that will foster meaningful social and community engagement for older adults, which may improve their quality of life
Health Care Utilization Among Homebound Elders
In this medically complex and highly dependent population, further study of how families and other caregivers impact health care utilization is needed
