Randomized trial of a collaborative palliative and oncology care intervention to improve communication about end-of-life care in patients with metastatic breast cancer

1008 Background: Studies have demonstrated the benefits of early, integrated palliative care in improving quality of life (QOL) and end-of-life (EOL) care for patients with poor prognosis cancers. However, the optimal timing and outcomes of delivering palliative care for those with advanced cancers that have longer disease trajectories, such as metastatic breast cancer (MBC), remains unknown. We tested the effect of a collaborative palliative and oncology care model on communication about EOL care in patients with MBC. Methods: Patients with MBC and clinical indicators of poor prognosis (N=120) were randomized to receive collaborative palliative and oncology care or usual care between 05/02/2016 and 12/26/2018. The intervention entailed five structured palliative care visits, including a joint visit with oncology when possible, which focused on symptom management, coping, prognostic awareness, decision-making, and planning for EOL. The primary outcome was documentation of EOL care discussions in the electronic health record. Patients also completed questionnaires at baseline and 6, 12, 18, and 24 weeks regarding communication with clinicians about EOL care, QOL, and mood symptoms. Results: The sample included only women (100.0%) who mostly identified as white (87.5%), with a mean age of 56.91 years (SD=11.24). The rate of EOL care discussions documented in the health record was higher among intervention patients versus those receiving usual care (67.2% vs 40.7%, p=0.006), including a higher completion rate of a Medical Orders for Life Sustaining Treatment form (39.3% vs 13.6%, p=0.002). Intervention patients were also more likely to report discussing their EOL care wishes with their doctor compared to usual care patients (OR=3.10, 95% CI: 1.21, 7.94, p=0.019). Study groups did not differ in reported QOL or mood symptoms. Conclusions: This novel collaborative palliative care intervention significantly improved communication and documentation regarding EOL care for women with MBC. Further work is needed to examine the effect of this care model on healthcare utilization at the end of life.
