Virtual Nurse and Social Worker Palliative Care Team to Improve Quality of Life in Veterans With Heart Failure or COPD (VITALVET:ADAPT)

Heart failure (HF) and chronic obstructive pulmonary disease (COPD) together affect nearly 1 in 4 Veterans and are among the leading causes of hospitalization, mortality, and poor quality of life in the Veterans Health Administration (VHA). Veterans with these conditions frequently experience depression (50-60%), anxiety (30-40%), breathlessness (44-85%), and fatigue (66-85%). Despite this burden, palliative symptom management and psychosocial support are not routinely delivered in primary care settings.

This study implements a virtual nurse and social worker palliative care team that provides direct patient care to Veterans with HF or COPD at high risk of hospitalization or death. The intervention was tested in a VHA-funded, patient-level randomized controlled trial across two VHA health systems, demonstrating clinically meaningful improvements in quality of life (primary outcome), depression, anxiety, and disease-specific health status at 4 and 6 months, with sustained quality of life effects at 12 months. Documentation of Veteran values and goals increased from 37% to nearly 80% in the intervention group vs. 42% in control.

The current study implements this evidence-based practice (EBP) in routine VHA care across 8 VA health care systems. A nurse and social worker( provide virtual care by phone or VA Video Connect directly to eligible Veterans, collaborating with each Veteran's primary care provider and palliative care clinician. The nurse conducts structured symptom assessments and uses motivational interviewing to help Veterans achieve activity, symptom reduction, and quality of life goals. The social worker delivers brief structured counseling based on behavioral activation and interpersonal psychotherapy, addressing activity goals, pacing, role change, and relaxation. Collaborative case review occurs weekly with a representative primary care provider and palliative care clinician, with placement of orders for the treating PCP to sign. Up to 30 Veterans per practice group per wave are reviewed for eligibility and up to 10 are expected to enroll per practice group per wave.

Practice groups within each site are randomized to one of six implementation waves in a cluster-randomized stepped-wedge design, with one practice group per site rolling out every 3 months beginning July, 2026, such that all 8 sites progress through the same 6-wave timeline in parallel. Covariate-constrained randomization was used to balance site-level characteristics (rurality and site engagement level) across the two implementation support conditions.

In addition to examining the effectiveness of the clinical intervention, this study compares two levels of implementation support. Four sites receive standard implementation support and four sites receive enhanced implementation support. Standard support includes site identification, clinician engagement, tailored training and implementation plans, fidelity monitoring, clinical office hours, adaptations tracking, sustainability planning, and dissemination of data and best practices. Enhanced support includes all standard components plus baseline process mapping, a brainwriting premortem exercise during pre-implementation, and during implementation: structured audit and feedback, updated process maps, and facilitation check-in meetings. During sustainability, enhanced sites additionally receive check-in meetings and emails. Both clinical effectiveness outcomes (Veteran-reported quality of life and related measures) and implementation outcomes (reach, adoption, fidelity, and sustainment) are examined across the two implementation support conditions.

A difference-in-differences analytic approach, aligned with the Callaway and Sant'Anna framework, is used to estimate causal effects of the intervention. Surveys of Veteran-reported outcomes are administered every 6 months to eligible Veterans at all practice groups throughout pre-implementation, implementation, and sustainment periods.
