About

Chronic heart failure (CHF), chronic obstructive pulmonary disease (COPD), and interstitial lung disease (i.e., pulmonary fibrosis) are common serious illnesses. Despite disease-specific medical care, people with these illnesses often left with poor quality of life (i.e., burdensome symptoms, impaired function). Furthermore, while these illnesses are leading causes of hospitalization and mortality, few people with these illnesses engage in advance care planning, the process of considering and communicating healthcare values and goals. The investigators are conducting a randomized clinical trial to study a symptom management, psychosocial care and advance care planning intervention to improve quality of life. The study is important because it aims to improve quality of life and provision of care according to peoples' goals and preferences in common, burdensome illnesses. Furthermore, this study will generate information that supports the broader dissemination and implementation of the intervention and informs the development of future palliative care and team-based interventions in the VA.

Full description

Chronic heart failure (CHF), chronic obstructive pulmonary disease (COPD) and interstitial lung disease (i.e., pulmonary fibrosis) have commonalities that make them ideal for early palliative care provided alongside disease-specific treatments. Quality of life is reduced in these illnesses because, despite disease-specific treatments, the same symptoms (e.g., shortness of breath, fatigue) often persist in these illnesses. Quality of life is also reduced because between 50-60% of people with either illness have clinically significant depressive symptoms. Finally, while CHF, COPD, and interstitial lung disease are leading causes of hospitalization and mortality, few people with these illnesses engage in advance care planning. Providing palliative care concomitantly with other medical care offers an important opportunity to improve quality of life and advance care planning for people with CHF, COPD, or interstitial lung disease. For other conditions such as lung cancer, when provided early, prior to the end of life, palliative care improves quality of life, depressive symptoms, and survival while reducing health care utilization. While palliative care has been well-studied in patients with advanced cancer, it has not been adequately studied in CHF, COPD, or interstitial lung disease. The goal of this project is to determine whether the benefits of early palliative care extend to CHF, COPD or interstitial lung disease.

The investigators developed and demonstrated early success with a patient-centered palliative care intervention to improve quality of life (i.e., symptoms, function) and advance care planning in CHF and COPD. The intervention consists of the following components: (1) algorithm-guided management of breathlessness, fatigue, and pain, provided by a nurse; the algorithms supplement disease-focused treatments with palliative and behavioral treatments; (2) a 6-session psychosocial care program targeting adjustment to illness and depression, provided by a social worker; and (3) engagement of patients and providers in advance care planning. The nurse and social worker are teamed with a palliative care specialist and representative primary care provider in brief weekly meetings. The team is integrated into primary care through nurse interaction with primary care providers and through electronic medical record communication.

The investigators will conduct a hybrid effectiveness and implementation study. Population-based sampling methods will be used to enroll 300 Veterans with CHF, COPD, or interstitial lung disease who have poor quality of life and are at high risk for hospitalization or death. The primary aim is to test the effectiveness of the intervention in a randomized controlled trial (intervention vs. enhanced usual care) in two VA health care systems. In a secondary aim, the investigators will examine the implementation of the intervention to guide future implementation and dissemination, increase the relevance to operational partners, and maximize the effectiveness of subsequent palliative care and team-based interventions.

Aim 1: Determine the effect of the intervention on (a) quality of life as a primary outcome, and (b) depression, symptom burden, advance care planning communication and documentation, disease-specific health status, emergency department visits, hospitalizations, and mortality as secondary outcomes.

Aim 2: Examine the implementation of the intervention.

Aim 2a: Assess the degree, barriers, and facilitators of implementation of various components. Identify which intervention components and processes are most critical from the perspectives of patients, intervention team members, and primary care providers whose patients received the intervention.

Aim 2b. Evaluate the resources (e.g., personnel time and other costs) associated with the intervention, and estimate the resources needed for implementation and maintenance in other VA settings.

The proposed study is significant because it addresses patient-centered needs in illnesses that are major sources of disability. The study is innovative because it tests the effectiveness of palliative care in CHF, COPD, and interstitial lung disease, leading causes of death among Veterans. In addition, the intervention is integrated into primary care, and the intervention components are structured to ease replication, implementation, and dissemination.

306 participants in 2 patient groups

ADAPT Intervention

Experimental group

Description:

The intervention includes 3 components: 1. nurse (RN) follows structured algorithms to help patients with symptoms, specifically breathlessness, fatigue, and pain. 2. social worker provides structured counseling targeting adjustment to illness and depression and advance care planning. 3. collaborative care model of care delivery, in which the nurse and social worker meet weekly with a primary care provider and palliative care specialist. This team makes medical recommendations to the intervention subjects' providers and supervises the nurse and social worker. The team has as-needed consultation with a cardiologist or pulmonologist. The nurse and social worker visits are in-person or by phone.

Treatment:

Behavioral: ADAPT Intervention

Enhanced usual care

No Intervention group

Description:

Patients in the control group will continue to receive care at the discretion of their providers, which may include referrals to and ongoing care from cardiology, pulmonary, palliative care, or mental health. They will also have the same amount of interaction with research assistants as the intervention patients, completing questionnaires and participating in study visits at the same frequency. Patients' providers will be given the results of baseline depression surveys if they screen positive for depression, and patients will be given an information sheet that outlines self-care for CHF or COPD.
