Many Veterans living with heart failure or chronic obstructive pulmonary disease (COPD) experience significant symptoms - such as breathlessness, fatigue, depression, and anxiety -that reduce their quality of life. Despite how common these symptoms are, they are often not adequately addressed in routine care. This study tests whether a virtual team of a nurse and social worker can improve quality of life, depression, anxiety, and other patient-reported outcomes for Veterans with heart failure or COPD who are at high risk of hospitalization or death. The nurse helps Veterans manage their most bothersome symptoms using a structured approach, and the social worker provides brief counseling to address emotional and psychological concerns. Both work closely with the Veteran's primary care provider and palliative care clinician to coordinate additional care as needed. The study also examines whether enhanced implementation support helps VA sites adopt the program more successfully compared to standard implementation support.
