Bristol trial finds no clear benefit in default dialysis planning for frail older patients

Researchers led by the University of Bristol and Bristol NHS Foundation Trust conducted a randomized trial involving 445 older adults with advanced kidney failure, ua.news reported. The nine-year trial enrolled participants across 31 kidney specialist centres in the United Kingdom, following them for an average of 4.5 years. Approximately 75% of the participants were aged 80 or older, while the remainder were aged 65 to 79 with additional coexisting health conditions. The study evaluated whether planning for kidney replacement therapy provided measurable gains compared to non-dialytic supportive treatment ua.newsua.newsua.newsOpen source ↗.

Trial outcomes and intervention uptake

Participants were randomized into two arms: one prepared for kidney dialysis, while the second entered a structured conservative management programme without dialysis. In the combined assessment of survival duration and health-related quality of life, neither strategy produced a superior outcome ua.newsua.newsua.newsOpen source ↗. According to the authors, only 28% of the patients who prepared for dialysis ultimately initiated the procedure. Overall, individuals in both trial cohorts were more likely to die from other underlying medical causes than to progress to the point of requiring dialysis treatment ua.newsua.newsua.newsOpen source ↗.

Clinical scope and therapeutic choices

The authors stated that these results do not apply to younger, physically fitter individuals or to patients who are already receiving maintenance dialysis. For those demographics, kidney replacement therapies and kidney transplantation remain the standard clinical pathways ua.newsua.newsua.newsOpen source ↗. Project lead Fergus Caskey stated that conservative management represents an active clinical approach rather than a passive option for older individuals presenting with multi-morbidity or frailty. The researchers noted that conservative care pathways maintain clinical flexibility, as enrolled patients can alter their decision and transition to dialysis should their condition require it ua.newsua.newsua.newsOpen source ↗.
