"It is not the fault of the health care team - it is the way the system works": a mixed-methods quality improvement study of patients with advanced cancer and family members reveals challenges navigating a fragmented healthcare system and the administrative and financial burdens of care.

Background: Healthcare fragmentation and lack of care coordination are longstanding problems in cancer care. This study's goal was to provide in-depth understanding of how the organization and fragmentation of healthcare impacts the experiences of patients with advanced cancer and their families, especially near the end-of-life.

Methods: This mixed-methods quality improvement study took place at a large multi-specialty healthcare organization in Northern California.
