Navigating Advanced Illness Goals And Treatment With Digital Engagement (NAVIGATE)

The goal of this two-armed, parallel-design, pre-/post-intervention assessment clinical trial is to learn if a digital and interactive website helps to improve advance care planning (ACP) engagement among caregivers of patients with serious illness. The main questions it aims to answer are: Does the website increase ACP engagement of caregivers of patients with serious illness? Researchers will compare the digital and interactive website to the usual care (a digital booklet) to see if the digital intervention works to improve ACP engagement among caregivers. Participants who are caregivers will: * Be introduced to a digital website and asked to explore the site over the course of the study. * Complete four self-administered questionnaires (baseline, one-week, six-week, and six-month). Participants who are patients will not have any intervention assigned and will only have their observational data collected through four interviewer-administered questionnaires (baseline, one-week, six-week, and six-month)
