Shared decision making (SDM) is a bidirectional approach in which healthcare providers and patients exchange information and determine treatment strategies based on the patient’s values and preferences, differing from traditional paternalism and informed consent. Incorporating SDM into the selection of renal replacement therapy (RRT) has been reported to improve outcomes and lead to more people with kidney failure feeling satisfied with their choice of dialysis modality. While the conventional SDM framework does not designate family members as key participants, in Asia, families often play a crucial role in treatment decision-making. Nevertheless, the impact of family involvement on the quality of decision making in RRT selection has not been sufficiently investigated either in Japan or internationally.
From October 2022 to February 2025, we conducted a cross-sectional study involving 475 adult patients with stage 5 chronic kidney disease (CKD) immediately after RRT selection across 49 institutions in Japan. The survey assessed (1) the final decision-maker for RRT and (2) each participant’s role in the decision-making process (whether limited to providing opinions or extending to involvement in the final decision). The quality of SDM was evaluated using the CollaboRATE scale, and analyses were performed with general linear models adjusted for age, socioeconomic factors, and duration of the patient–physician relationship.
(1) The most common final decision-maker for RRT selection was “patient only” (46.5%), followed by “physician and patient” (20.0%) and “patient and key person” (13.8%). The mean SDM score was 84, with 36% of patients giving the maximum score. Compared with decisions made by “physician only,” SDM scores were 12.3 points higher (95% CI: 1.5–23.2) in the “physician and patient” group and 13.7 points higher (95% CI: 0.8–26.7) in the “patient, physician, and key person” group. These differences were even more pronounced among patients with family involvement. (2) Regarding the relationship between roles in RRT selection and SDM scores, compared with decisions made by “physician only” or “key person only” (i.e., without patient involvement), the “joint decision-making” group (with physician or key person) had scores that were 10.0 points higher (95% CI: 3.2–16.8). Among patients with family involvement, significant increases in SDM scores were observed in the “patient only,” “patient-led decision after considering physician/key person opinions,” and “joint decision-making with physician/key person” groups, with respective increases of 9.5, 10.4, and 12.1 points.
The quality of SDM in RRT selection was suggested to be enhanced when family members, in addition to patients, were involved. Moving forward, the practice of SDM that respects patients’ values while also considering the role of family is expected to contribute to improving the quality of RRT selection in Japan.
