RESUMO
In order to understand the actual needs and influencing factors of cancer patients to participate in medical decision-making, 29 cancer patients were selected for semi-structured interviews by purpose sampling from September 2020 to February 2021, and the data were analyzed by substantive coding step by step according to interview method. The results showed that the quality of patient-clinician interaction was an important factor influencing the decision quality. The elements for cancer patients to participate in medical decision-making include: patients’ disease knowledge, awareness of choice, communication duration, support from family members and doctors, and mutual trust between doctors and patients. Medical staff should respect patients’ preference to participate in medical decision-making, break the medical-centered system arrangement, help patients obtain services matching their preferences for participating in decision-making, and achieve a pattern that is beneficial to both patients and the medical system.
