4R Oncology® model in breast and lung cancer clinics has improved patients’ involvement in organizing their care, enabled the development of high-functioning multidisciplinary care teams, and helped optimize the timing and coordination of sequence of care
The4R Oncology® Model facilitates enhanced patient engagement and timely care provision by streamlining delivery of complex interdependent care. Implementation of the 4R Oncology® model in breast and lung cancer clinics has improved patients’ involvement in organizing their care, enabled the development of high-functioning multidisciplinary care teams, and helped to optimize the timing and coordination of sequence of care. In this episode, CANCER BUZZ speaks with Raymond Liu, MD, director of research of Hematology-Oncology in Kaiser Permanente Northern California, director of cancer survivorship in Kaiser Permanente San Francisco, and assistant clinical professor at UCSF, who shares how successful implementation of the 4R Oncology® model empowers patients and clinicians and coheres care teams.
“When people could see that plan, and they could bring that home with them, and they saw that it was all guideline-based and mapped through in a very, very detailed way, they were empowered to answer their questions, especially for their loved ones, and to really reflect on what was said [in the doctor-patient consultation] at home.” –Raymond Liu, MD
“Care is so complex now; our innovations are really, really going fast but we have not been able to deliver the care in a way that’s understandable sometimes, and so by putting it in a single care plan, the patients really engage with it, and we found that the call volumes came down.” –Raymond Liu, MD
