A UK randomized trial involving 445 older adults with kidney failure and additional health problems found no overall advantage for preparing for dialysis over structured conservative kidney management when survival and quality of life were considered together. Only 28% of participants assigned to prepare for dialysis started it. The findings do not apply to younger, fitter people or those already receiving dialysis.
A randomized UK trial of 445 older people with kidney failure found no overall advantage to preparing for dialysis over a structured care plan without dialysis when survival and quality of life were considered together. The findings, published in The Lancet, challenge the idea that dialysis should automatically be the next step for older adults with frailty or multiple health conditions, while leaving treatment choice with each patient.
The Prepare for Kidney Care trial recruited participants at 31 UK kidney centers, representing about half of the country’s kidney services. Around 75% were aged 80 or older; the remainder were aged 65 to 79 and had additional health problems. Participants were randomly assigned to prepare for renal dialysis or for responsive management, a form of conservative kidney care that does not include dialysis, and were followed over time.
Across an average 4.5 years of follow-up, neither approach produced better outcomes when length and quality of life were assessed together, according to the study report. In the group preparing for dialysis, 28% went on to start treatment. The researchers said participants in both groups were more likely to die from other causes than to need dialysis, reflecting the vulnerability and complex health needs of the population studied.
The study took nine years to complete, including seven years of recruitment. Participants could leave the trial and change their treatment pathway. The report describes conservative kidney management as active care without dialysis, rather than no treatment. It does not provide a reason to stop dialysis for people already receiving it.
Why Treatment Planning May Change
The findings give patients, families and kidney-care teams evidence to discuss options when an older person has kidney failure alongside frailty or other serious health conditions. A plan focused on dialysis preparation does not mean every patient will start dialysis: in this trial, fewer than one in three people assigned to prepare for it did so. The results support conversations that account for a person’s priorities, health and likely care needs rather than treating dialysis as automatic.
For services, the findings raise practical questions about whether patients can access structured conservative care and receive enough information and support to choose between pathways. Kidney Care UK policy director Fiona Loud said staff also need support to help patients make choices that work for them, and that care should be available wherever a person lives. The trial provides evidence for discussion, but does not by itself establish how NHS policy or local services will change.
The trial’s conclusion is specific: the two approaches had similar outcomes when survival and quality of life were considered together in this older, medically complex group. That does not mean the choices are identical in their demands, benefits or burdens for an individual. The study report says both have pros and cons; those trade-offs need to be discussed with the person receiving care.

Who the Trial Results Cover
Before this study, the researchers said there was limited high-quality evidence comparing dialysis planning with conservative kidney management for older people with kidney failure and frailty or multiple health conditions. The trial was designed to examine both survival and quality of life and to help patients and families make informed decisions, as well as inform NHS care policy.
Its results are not intended to change the standard approach for younger and fitter patients, for whom dialysis and transplantation remain standard care, according to the report. They also do not apply to people already on dialysis. The study addresses a particular planning decision for older, medically complex patients; it is not a general comparison for everyone with advanced kidney disease.
Fergus Caskey, the University of Bristol renal medicine professor who led the project, said conservative management is increasingly recognized internationally, but evidence comparing it with dialysis had been limited. The study’s randomized design adds evidence for the group it recruited, while its long recruitment period and participant profile define how broadly the results can be applied.
“The findings will help support more personalized care, patient choice and better-informed decisions.”

Limits and Open Questions
The report gives the overall comparison but does not provide detailed outcome figures in the supplied material, including separate survival and quality-of-life results, or explain how different patient characteristics may have shaped individual outcomes. It is therefore not possible from these details to identify which approach might suit a particular person. The finding of similar outcomes applies to the trial group and its combined measure, not necessarily to every patient or to each outcome considered separately.
It also remains unclear whether the results will lead to changes in NHS policy, local care pathways or access to conservative management. The trial authors and quoted experts support informed choice, but the report does not set out a specific policy change or timetable. The study does not compare stopping dialysis with continuing it, and it cannot establish that one approach is preferable for younger or fitter patients.
How Kidney Teams May Apply Evidence
The next step for patients and clinicians is to use the findings in individual treatment discussions, weighing the options against the person’s health, needs and preferences. Conservative kidney management remains active care, and the report says patients can change their minds and move to dialysis. Any decision should be made with the treating kidney team rather than inferred from the trial’s group-level results.
Researchers and health services may consider how the evidence should inform care guidance and whether patients across the NHS can access the support needed to make a choice. The supplied report does not announce a policy review, implementation date or further trial. For now, the confirmed development is new comparative evidence for older adults with frailty or additional health conditions, alongside a continuing need to understand how it will shape services.
Key Questions
What did the Prepare for Kidney Care trial find?
Among the older, medically complex participants studied, preparing for dialysis and preparing for conservative kidney management had similar outcomes when survival and quality of life were considered together.
Did everyone assigned to prepare for dialysis start treatment?
No. The report says 28% of participants in the dialysis-preparation group went on to start dialysis during the study.
Does conservative kidney management mean no treatment?
No. The report describes it as active care without dialysis. It also says patients can change their treatment pathway and move to dialysis if they choose.
Do these findings apply to all people with kidney failure?
No. The results concern older adults with frailty or other health problems. The report says they do not apply to people already receiving dialysis or to younger, fitter patients, for whom dialysis and transplantation remain standard care.
Does the trial mean dialysis should be avoided?
No. It found no overall advantage for either approach on the combined measure of survival and quality of life in the group studied. It supports discussing both options with a kidney-care team, not a blanket recommendation against dialysis.
