Perspectives on the optimal timing of advance care planning among Japanese patients undergoing dialysis and clinicians: a cross-sectional study.

KEY MESSAGES: The majority of dialysis patients and clinicians favor early advance care planning in our sample. Yet, there is a disconnect: only 11% of patients discussed future care with their clinicians. Our findings indicate Japanese dialysis patients and clinicians support proactive advance care planning at or before dialysis initiation.

BACKGROUND: Little is known about the optimal timing of discussions about advance care planning among dialysis patients and clinicians engaged in dialysis care. We aimed to explore the preferred timing for advance care planning and assess actual participation in advance care planning among dialysis patients and their clinicians.

METHODS: A scenario-based survey on Japanese patients aged ≥65 years on dialysis and clinicians involved in their dialysis care was performed. Participants were asked if they would feel prepared to engage in advance care planning with their clinicians, offering a choice among four hypothetical stages within the illness trajectory, extending from the initiation of dialysis to a later phase characterized by the patient's extreme frailty.

RESULTS: Overall, 181 patients and 128 clinicians participated in the study. Among these, 131 (72%) patients, and 84 (66%) clinicians indicated that they would prefer to initiate advance care planning around the time of dialysis initiation. Only 20 patients (11%) indicated that they had participated in advance care planning with at least one clinician, including 11 (6%) who indicated that they had discussed their preferences around life-sustaining treatments and 8 (4%) who had discussed their preferences around dialysis continuation.

CONCLUSIONS: While fewer than 11% of patients undergoing dialysis and their clinicians enrolled in our study had participated in advance care planning, most indicated that they would be comfortable initiating the discussion around the time of dialysis initiation. These findings suggest untapped opportunities to engage patients in advance care planning early in the course of their dialysis.
