Patient-centered and Efficacious Advance Care Planning in Cancer: the PEACe Comparative Effectiveness Trial

Study investigators will conduct a single-blind, patient-level randomized trial to compare the effectiveness of two different patient-facing advance care planning (ACP) interventions. Investigators will enroll 400 patients with advanced cancer and their family caregivers to receive either (1) in-person discussions with trained facilitators or (2) web-based ACP using interactive videos. Because these approaches have never been compared directly, it is unclear whether one form of advance care planning is more potent, and if so, for whom and under what circumstances. Aim 1 compares the effectiveness of in-person, facilitated ACP versus web-based ACP on patient and family caregiver outcomes (ACP engagement, ACP discussions, advance directive completion, goal attainment, and caregiver psychological symptoms). Aim 2 assesses implementation costs of each intervention and effects on healthcare utilization at end of life. Aim 3 identifies contexts and mechanisms influencing the effectiveness of each approach. Primary patient outcomes will be assessed at 12 weeks. Participants will be followed until 12 weeks after the patient's death or completion of the 48-month data collection period, whichever occurs first. In-depth interviews with patients, caregivers, and clinicians will begin in Year 2 of the grant and continue until thematic saturation is reached.
