Interdisciplinary teamwork. Palliative care, also known as hospice care, is a new branch of clinical medicine. It is to solve the physical, psychological, social and spiritual pain of patients who can't stand high-intensity treatment and pursue the peace and dignity of death. The necessary condition for its implementation is interdisciplinary teamwork, which regards death as a normal process and truly achieves the purpose of neither intentionally accelerating death nor intentionally delaying death.
