Study Details

Brief summary:

The goal of this pilot study is to understand and improve the shared decision-making process between people with advanced breast cancer and their providers regarding their care and treatment. As part of this study, the researchers will evaluate a decision support tool called COAST that was designed to support patients and providers in having meaningful conversations. The main questions it aims to answer are:

1. Can the COAST tool improve the quality of communication between patients and their oncology providers?
2. Is the COAST tool acceptable, appropriate, and easy to use at NYP-Weill Cornell Medicine, NYP-Brooklyn Methodist Hospital and NYP-Queens?

Participants will be asked to fill out two surveys: one before they use the COAST tool and another about 2 - 4 weeks later. Some patients will also be invited for an interview.

Decision Support Tool

The COAST decision support tool will be available in two formats: a booklet and a website. It will provide information about advanced breast cancer and the available treatment options.
