376 Background: Patients with metastatic cancer have unique survivorship needs. Recent studies show patients with advanced cancer have unmet needs in the following categories: health information (31%), psychosocial support (27%), symptom management and general wellness support (23%) (Hart, et al., 2022). The Living Well with Advanced Breast Cancer Clinic (LWABC) was established in 2017 to address these unmet needs. This multidisciplinary clinic provides the patient and caregiver(s) an individual visit with a medical oncologist, integrative medicine physician, palliative medicine physician, dietitian, and nurse navigator. The patient is provided in-depth education and personalized supportive care plans. Methods: Over recent years, clinic staff have utilized the Plan, Do, Study, Act (PDSA) (Taylor, et al., 2014 ) methodology to refine operations and improve patient care. In 2021, the plan phase was initiated with incorporation of a nurse navigator and program manager for the clinic. Nurse navigation services have been shown to improve patient and caregiver knowledge as well as quality of life and was deemed an important addition to the program (Oncology Nursing Society, 2018). At the beginning of calendar year 2022, in the “do” phase, the nurse navigator/program manager was hired and implemented pre-visit phone calls as well as navigation services for patients. These services include assessment of needs, patient education, provision of community resources, and assistance with scheduling referrals. At the beginning of calendar year 2023, use of the NCCN distress thermometer and problem list was initiated. The current phase, “study,” includes development of a dashboard for monitoring clinic operations. Review and assessment of distress thermometer data is ongoing. Results: When comparing calendar year 2021 to 2022, the clinic has seen increases in referrals (40 in 2021 to 65 in 2022), number of patients seen (31 in 2021 to 46 in 2022), and unique patient zip codes (28 in 2021 to 42 in 2022). There was also a reduction in late cancellation rates from 15.9% (2021) to 7.2% (2022). Late cancellation is defined as any appointment cancelled 24 hours or less prior to scheduled visit. Conclusions: Utilizing the PDSA cycle clinic staff have seen operational improvements over the last two years. Currently, this supportive care program remains in a “study” phase and will continue to evaluate progress and patient outcomes. Results from the act phase will be utilized to continue expansion of the clinic and services in the future. Further aiding this endeavor is an embedded patient advocate and ongoing outreach and collaboration with patient support organizations.
