PREPARE is a website (www.prepareforyourcare.org) that teaches patients how to identify what is most important in life, how to communicate their preferences to clinicians and loved ones, and how to make informed decisions. It is written at a 5th grade level and includes voice-overs of text and closed captioning of videos that model advance care planning behaviors. The goal of this proposal is to test the efficacy of PREPARE plus an easy-to-read advance directive, versus an advance directive alone, to improve patient engagement in multiple advance care planning behaviors including discussions with surrogate decision makers and clinicians in addition to advance directive completion. The investigators will also determine whether PREPARE can empower and activate patients within clinical encounters with their clinicians and help to decrease health disparities in advance care planning.
