The Prepare for Kidney Care trial compared planning for dialysis with conservative kidney management among 445 older adults with kidney failure and frailty or other health problems. Over an average 4.5 years, neither approach produced better outcomes when survival and quality of life were considered together; the researchers say decisions should be individualized, not based on dialysis as the automatic default.
A randomized UK trial found that preparing for dialysis did not produce better combined survival and quality-of-life outcomes than preparing for conservative kidney management among older people with kidney failure who were frail or had multiple health conditions. The findings challenge the idea that dialysis should be the automatic next step for this group, while not applying to younger, fitter patients or people already receiving dialysis.
The Prepare for Kidney Care trial, led by the University of Bristol with Bristol NHS Foundation Trust, enrolled 445 participants across 31 UK kidney centers. About three-quarters were aged 80 or older; the remaining participants were 65 to 79 and had additional health problems. Researchers randomly assigned participants to prepare for dialysis or for responsive management, a form of conservative kidney care that does not include dialysis.
During an average 4.5 years of follow-up, the trial found neither approach resulted in better outcomes when length and quality of life were considered together. Among those assigned to prepare for dialysis, 28% went on to start it. The report says participants in both groups were more likely to die from other causes than to require dialysis, reflecting the vulnerability and complex health needs of the people studied.
The study took nine years to complete, including seven years of recruitment. Participants could leave the trial or change their treatment pathway. The researchers describe conservative management as active care without dialysis, rather than an absence of treatment. The published summary does not provide further detail on individual symptoms, service use or outcomes within particular subgroups.
Making Kidney Treatment a Choice
The findings offer patients, families and clinicians comparative trial evidence for a decision that can shape daily life and care. For an older person with frailty and other illnesses, the question is not simply whether dialysis is available; it is whether the likely benefits and demands of treatment fit that person’s priorities. The trial suggests that planning for dialysis is not automatically superior when survival and quality of life are considered together in this study population.
That does not establish that the two approaches are identical for every individual, or that dialysis should be withheld. Rather, it supports discussing both pathways, including their trade-offs, and involving patients in decisions. The report’s contributors say staff need support to offer informed choices consistently. How services can provide that support across the NHS remains a policy and implementation issue, not a result settled by the trial itself.

Who the Trial Studied
People with advanced kidney disease may face decisions about whether to prepare for dialysis or receive conservative kidney management. The trial focused specifically on older adults with kidney failure and frailty or other health conditions, a group for whom clinicians and families have had limited high-quality comparative evidence, according to the researchers and policy contributors quoted in the report.
The results should not be extended to all people with kidney failure. The report explicitly says they do not apply to people already on dialysis or to younger and fitter patients, for whom dialysis and transplantation remain standard care. The trial compared preparation for two care approaches; it was not a study of stopping dialysis in people already receiving it.
“The findings will help support more personalized care, patient choice and better-informed decisions.”
— Professor Fliss Murtagh, director of the Wolfson Palliative Care Research Center at Hull York Medical School
Limits of the Trial Findings
The reported findings do not show which option is preferable for every patient, and the summary does not give detailed results for specific subgroups or separate measures of quality of life and survival. It reports no overall advantage when those outcomes are considered together. The 28% figure applies to participants assigned to prepare for dialysis; it does not mean that dialysis is unnecessary for all older adults.
The trial also cannot answer questions about patients already receiving dialysis or younger, fitter people, who were outside the group to which the authors say the results apply. The report does not specify how the findings will change NHS policy, or what services and staffing would be needed to make both approaches available consistently. Individual outcomes and preferences may differ.
Applying Evidence in Care
The immediate next step is for clinicians and patients to use the evidence in discussions about care options, while weighing an individual’s health, preferences and circumstances. Kidney Care UK and the other contributors called for patients and families to receive clear information and for staff to have the support needed to guide those conversations.
The report says the findings may inform NHS policy, but it does not announce a specific policy change or timetable. Further interpretation and practical planning will be needed to determine how services can offer responsive conservative management alongside dialysis planning. Patients can change their pathway, according to the trial description, and the research team says participants retained that choice throughout the study.
Key Questions
What did the kidney care trial find?
In the study group of older people with kidney failure and frailty or other health problems, neither preparing for dialysis nor conservative kidney management produced better outcomes when survival and quality of life were considered together over an average 4.5 years.
What is conservative kidney management?
In the report, it is described as active treatment without dialysis. It is an alternative care pathway, not an absence of care; participants could change their treatment pathway.
Does the study mean older people should avoid dialysis?
No. The researchers say neither approach should be the default for the older, frail population studied. Decisions remain individual, and the results do not apply to people already receiving dialysis or to younger, fitter patients.
How many people who planned for dialysis started it?
Twenty-eight percent of participants assigned to prepare for dialysis went on to start treatment during the study. This figure describes that trial group, not all older people with kidney failure.
Will the findings change NHS policy?
The researchers said the trial was intended to help inform NHS policy, and an NHS England renal services director described it as important new evidence. The report does not announce a specific policy change or implementation schedule.
