Utilizing an innovative digital collaboration tool to impact shared decision making, health equity and trust with a focus on advance care planning for patients with metastatic breast cancer.

e24123 Background: Advance care planning (ACP) has been associated with improved quality of life, increased use of hospice and palliative care, and less use of extreme treatments close to death. These conversations often do not occur and documentation rates of ACP in oncology patients have been as low as 10%, with rates of documentation increasing between 30-40% in intervention studies. The present study aimed to examine the effectiveness of an online Advance Care Appointment Companion (ACAC) collaboration tool to improve communication and elevate trust between MBC patients and their oncologist and increase completion rates of ACP documents. Methods: Data were collected from 48 patients with mean age of 66.9 years (SD = 6.97) with MBC during their medical oncology appointments (Time 1) and three months later (Time 2) at the Koontz Center for Advanced Breast Cancer. At Time 1, patients were enrolled on the ACAC platform and then completed questions in the clinic or at home about completion status of a healthcare directive and durable power of attorney (DPOA) for healthcare, comfort in discussing ACP with their care team and loved ones, and goals of care at end of life. A summary of these responses with a provider prompt script was securely sent to the oncologist prior to each appointment and used to discuss ACP over the three-month study period. Descriptive statistics, t-tests, McNemar-Bowker and McNemar’s tests were conducted to examine changes in rates of ACP document completion, patient reported levels of comfort in discussing ACP, and quality of life preferences. Results: The study included a diverse sample of female MBC patients including 79% White, 19% Black/African American, 2% Mixed Race; 6% less than a high school degree, 17% high school or GED, 19% some college, and 58% associate’s degree or above. Results showed a significant increase in completion of a healthcare directive (Time 1 = 10.4%, Time 2 = 37.5%, p < .01) and DPOA (Time 1 = 31.5%, Time 2 = 56.3%, p < .01) and improved comfort discussing ACP with their care team (p < .01) and loved ones (p < .01) from baseline to follow-up. Significantly more patients reported that they would not want CPR (p < .05) at follow-up and all of these patients had reported that they were unsure at baseline. On average, ACP conversations during medical appointment took 5 minutes to discuss. Conclusions: Results show that the ACAC is an inclusive solution which provides equitable access to patients. This tool facilitates enhanced patient provider communication and assists patients with MBC in finalizing decisions regarding their goals of care, leading to increased completion and proper submission of ACP documentation. Future research should examine how the ACAC can decrease financial toxicity, utilize internal resources, and address social determinants of health.
