A randomized UK trial of 445 older adults with kidney failure and frailty or other health conditions found neither preparing for dialysis nor structured conservative kidney management led to better outcomes 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 on dialysis.
A UK randomized trial of 445 older adults with kidney failure and frailty or multiple health conditions found no advantage for either preparing for dialysis or structured kidney care without dialysis when survival and quality of life were considered together. The findings, published in The Lancet, challenge treating dialysis as the automatic next step for this group, while leaving individual treatment choices with patients and their care teams.
The Prepare for Kidney Care trial, led by the University of Bristol with Bristol NHS Foundation Trust, recruited participants through 31 UK kidney centers, about half of the country’s kidney services. Roughly three-quarters were aged 80 or older. The rest were 65 to 79 and had additional health problems. Participants were randomly assigned to prepare for dialysis or for responsive management, a form of conservative kidney management that does not include dialysis, and were followed over time.
Across an average 4.5 years of follow-up, neither approach produced better outcomes on the combined measure of length and quality of life, according to the report. Among those preparing for dialysis, 28% went on to start treatment. Participants in both groups were more likely to die from other causes than to reach the point of requiring dialysis, reflecting the serious health needs of the population studied.
The trial took nine years to complete, including seven years of recruitment. Participants could withdraw at any time and could change their treatment pathway. The researchers say the results apply to older people with kidney failure and frailty or other health conditions—not to people already receiving dialysis, or to younger and fitter patients, for whom dialysis and transplantation remain standard care.
Why Dialysis Is Not Automatic
The findings add randomized evidence to a decision that can affect a person’s daily routine, independence and comfort, as well as their medical care. Dialysis can involve substantial treatment demands, while conservative kidney management is an active care approach without dialysis. The trial did not show that either option is better overall for the group studied, so a default pathway could fail to reflect an individual’s priorities and health circumstances.
The result is not that dialysis should be withheld. Rather, the study supports discussing both approaches with eligible older patients and their families. The trial’s lead, Fergus Caskey, said both options are worth considering and have pros and cons. Patient-support and palliative-care representatives likewise stressed informed, shared decisions and care that reflects what matters to the person.
The findings may inform clinical conversations and NHS policy, but they do not establish that every patient will have the same experience. Individual outcomes and treatment needs vary, and the study compared group outcomes rather than prescribing a single choice for any one patient.

A Trial Built for Older Patients
Evidence comparing dialysis with conservative kidney management has been limited, particularly for people who are older, frail or living with several health conditions. The Prepare for Kidney Care study was designed to address that gap by randomly assigning participants to prepare for one of two approaches and tracking both quality of life and survival.
Randomization makes this a different kind of evidence from studies that simply compare people who chose different treatments. However, the trial was challenging to conduct: recruitment lasted seven years, and the full study took nine. The design preserved participants’ ability to withdraw or change course, recognizing that decisions about kidney care can evolve.
Conservative kidney management is not the absence of care. It is a structured approach that does not include dialysis. Kidney Care UK policy director Fiona Loud said patients can change their mind and move to dialysis if they wish. The study’s scope remains specific to older adults with complex health needs; it does not overturn established treatment for younger, fitter patients.
“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 the University of Hull
Limits of the Trial Findings
The report establishes similar outcomes between the two assigned approaches when survival and quality of life are considered together; it does not show that every outcome, experience or individual patient result was identical. The supplied report does not provide detailed numerical results for separate quality-of-life measures or survival comparisons, so those cannot be specified here.
It is also unclear from the report how the findings may affect NHS policy or how consistently services can offer both approaches. The results should not be extended to people already on dialysis, or to younger and fitter patients. As with any care decision, the best option for a particular person depends on their health, preferences and clinical circumstances.
How Care Teams May Apply Results
The findings provide evidence for discussions between patients, families and kidney-care teams, and may inform future NHS policy decisions. The source material does not announce a specific policy change or implementation timetable. For now, the next step is for clinicians to explain the available approaches, their potential trade-offs and the limits of the trial evidence, then support patients in choosing a care pathway that fits their circumstances.
Researchers and health services will need to consider how to make informed choice practical across kidney centers, including staff support and access to conservative care. Patients who choose conservative management may still change their minds and pursue dialysis. The trial does not set a new universal treatment rule; it challenges the assumption that dialysis should be the default for every older, frail person with kidney failure.
Key Questions
What did the kidney care trial find?
Among 445 older UK participants with kidney failure and frailty or other health conditions, the trial found neither preparing for dialysis nor conservative kidney management led to better outcomes when survival and quality of life were considered together.
Does this mean older adults should avoid dialysis?
No. The study does not say dialysis should be avoided. It suggests it should not automatically be the default for the specific group studied. Treatment decisions should be made with a kidney-care team and reflect a patient’s health and preferences.
What is conservative kidney management?
In this study, it was a structured form of care for kidney failure that does not include dialysis. It is an active treatment approach, and the source says patients can change their minds and move to dialysis.
How many participants assigned to prepare for dialysis started it?
Twenty-eight percent of participants preparing for dialysis went on to start treatment during the study, according to the report.
Who do the results apply to?
The findings concern older people with kidney failure who also had frailty or multiple health conditions. 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.
