Background: Patients newly-diagnosed with advanced cancer often rely on family caregivers to provide daily support to manage healthcare needs and maintain quality of life. Early telehealth palliative care has been shown to effectively provide an extra layer of support to family caregivers, however there has been little work with underserved populations, especially African-Americans and rural-dwellers. This is concerning given the lack of palliative care access for these underserved groups. Study design: Single-site, small-scale pilot randomized controlled trial (RCT) of Project ENABLE (Educate, Nurture, Advise, Before Life Ends) Cornerstone, a lay navigator-led, early palliative care coaching intervention for family caregivers of African-American and rural-dwelling patients with newly-diagnosed advanced cancer. Family caregivers are paired with a trained lay navigator overseen by specialist palliative care clinicians and receive a series of brief in-person and telehealth sessions focusing on stress management and coping, caregiving skills and organization, getting help, self-care, and preparing for the future/advance care planning. This pilot trial is assessing acceptability of the intervention, feasibility of recruitment and data collection procedures, and preliminary efficacy compared to usual care on caregiver and patient quality of life and mood over 24 weeks. Conclusion: Once acceptability and feasibility are determined and issues addressed, the ENABLE Cornerstone intervention for underserved family caregivers of persons with advanced cancer will be primed for a fully powered efficacy RCT. Given its use of lay navigators and telehealth delivery, the intervention is potentially highly scalable and capable of overcoming many of the geographic, human resource, and cultural obstacles to accessing early palliative care support.
