Overview

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)

4c. Patients with CKD Stage 4 and 5, identified at G4 or G5 of CKD, glomerular filtration rate (GFR) 30 ml/min or less, inclusive of kidney failure on kidney replacement therapy; and (5) Physicians assessment that ACP is appropriate for the patient by physicians. () The attending clinicians may base the assessment of ACP appropriateness on several factors in addition to high mortality risk. As a baseline, clinicians are asked to base their assessment of high mortality risk using the validated "Surprise" question.
