This paper describes a technology program aimed at developing technical skills and confidence, reducing social isolation and loneliness, and increasing healthcare self-management and self-efficacy among older adults. We conducted a mixed-methods study using surveys collected at baseline and 12 months from 90 older adults. Focus group data ( = 7) collected at 12 months were examined for convergence with key quantitative outcomes, emergent value-related themes, and evaluation of program structure and staff.

Background: National guidelines recognize lifetime trauma as relevant to clinical care for adults nearing the end of life. We determined the prevalence of early life and cumulative trauma among persons at the end of life by gender and birth cohort, and the association of lifetime trauma with end-of-life physical, mental, and social well-being.

Methods: We used nationally representative Health and Retirement Study data (2006-2020), including adults age > 50 who died while enrolled (N = 6495).

Social isolation and loneliness are associated with poor health and higher health care costs among older adults. Our objective was to determine if older adults identified as at risk for loneliness by a Medicare Advantage health plan could benefit from a proactive telephone support program. We conducted a mixed-methods pilot efficacy study of outbound calls from an established community-based telephone program to support older adults identified as at risk for loneliness.

Background: Patients with lung cancer, idiopathic pulmonary fibrosis (IPF), and COPD have high symptom burden, poor quality of life, and high health care use at the end of life. Although proactive integration of palliative care in lung cancer can improve outcomes, it is unclear whether similar practices have been adopted in COPD and IPF care.

Research Question: Do patients with COPD and IPF have different patterns of health care and palliative care use at the end of life compared with patients with lung cancer?

Study Design And Methods: We retrospectively identified deceased patients with lung cancer, COPD, or IPF with ≥ 1 outpatient visit at the University of California, San Francisco, in the last 6 months of life.

Background And Objectives: Persons with dementia and their care partners have known risks for loneliness and social isolation throughout the disease trajectory, yet little is described about social lives in a population heterogeneous for disease stage, syndrome type, and setting.

Research Design And Methods: We conducted a secondary analysis of qualitative interviews from multiple studies to triangulate responses from a cohort of persons with dementia (n = 24), and active (n = 33) or bereaved (n = 15) care partners diverse in setting, dementia type and stage, and life experience. Interviews explored challenges related to social lives and were analyzed thematically.

Telemedicine has the potential to improve access to cancer care, particularly for patients with functional limitations, high symptom burdens, or financial or geographic constraints. However, there is also a risk that telemedicine can widen healthcare disparities among patients facing systemic disadvantages like those with technological barriers, poor digital literacy, older age, or non-English language preferences. To optimize telemedicine usage, we must implement practical strategies like video onboarding programs, user-friendly technology platforms, optimizing the clinician's environment, and best practices for using interpreters.

Importance: The potential role of living alone in either facilitating or hampering access to and use of services for older adults with cognitive impairment is largely unknown. Specifically, it is critical to understand directly from health care and social services professionals how living alone creates barriers to the access and use of supportive health care and social services for racially and ethnically diverse patients with cognitive impairment.

Objective: To identify the potential role of living alone in the access and use of health care and social services for diverse patients with cognitive impairment by investigating professionals' perceptions of caring for such patients who live alone in comparison with counterparts living with others.

Objectives: We examine the relationship between social isolation, poor health behaviors, and the perceived worsening of older adults' health behaviors following the coronavirus outbreak. We assess the extent to which psychological pathways mediate the relationship between social isolation and worsening health behaviors.

Methods: Drawing on data from the National Social Life Health and Aging Project Round 3 (2015) and its coronavirus immune disease 2019 (COVID-19) substudy (2020; N = 2,549), we use generalized linear models to explore how indicators of social isolation during the COVID-19 pandemic-infrequent in-person contact with friends and family in 2020 and decreased in-person contact with friends and family since COVID-19 started-are associated with (1) poor health behaviors (low physical activity, drinks per week, smoking, and poor sleep) in 2020 and (2) perceived worsening of health behaviors (reports of decreased physical activity, increased drinking and smoking, and feeling less rested) since the pandemic started.

This study investigated how older adults adopted new technologies in response to sudden social isolation caused by the COVID-19 pandemic and how this adoption was related to their long-term psychosocial well-being. The study involved a 6-month longitudinal survey of 151 older adults and two phone-based focus groups, which informed a semi-structured interview guide and purposive sampling of diverse community-dwelling older adults. We then conducted twenty qualitative interviews and thematic analysis and mapped themes to 6-month quantitative trajectories of psychosocial health.
