Encouraging Older Adults and Adults With Serious Illness to Designate a Health Care Proxy
Sponsor: University of Southern California
Summary
This study is a Stage III randomized trial to encourage patients in advance of a health care appointment to designate a healthcare proxy. Patients will be randomly assigned to receive a mailer containing information about designating a healthcare proxy, or to not receive any mailer. For patients assigned to receive a mailer, the mailer will differ by the presence or absence of a patient pre-commitment prompt, and contain a personalized provider request or a generic health system request. The work will evaluate the randomized trial and identify factors that predict intervention effectiveness.
