Summary
Brief summary (as posted)
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.

- description
- The proportion of patients who agree with the acceptability of the COAST decision support tool is measured by the Acceptability of Intervention Measure (AIM). This tool consists of four items designed to monitor and evaluate the success of implementation efforts. Respondents can rate each item on a scale from 1 (completely disagree) to 5 (completely agree). Higher scores reflect greater agreement with the acceptability of the intervention. Patients with a score of 4 or higher will be included in the numerator, while all patients who complete the measure will be included in the denominator. We will define COAST as "acceptable" if this proportion is greater than 70%.
