A study from the UK's National Institute for Health and Care Research (NIHR), published in The Lancet, has found that a structured, less medicalised approach to kidney failure could offer older patients an alternative to dialysis without shortening their lives or lowering their quality of life, according to ConSalud. The trial followed 445 participants across 21 specialist kidney centres in the UK — about half of the country's specialised services — over a mean follow-up period of 4.5 years. Roughly three-quarters of the participants were 80 or older, and the rest were aged 65 to 79; all had additional health problems.
Why it matters
Chronic kidney disease affects around seven million people in Spain, roughly 15% of the population, ConSalud reports. In many cases patients are put on dialysis, a procedure that filters fluids, electrolytes and waste products from the blood. It is particularly common among older patients, and the NIHR study set out to test whether that default is always the right one.
The question the researchers posed was direct: for older people with kidney failure alongside other conditions or frailty, does the standard route of preparing for dialysis serve them better than a conservative care programme? The answer, according to the trial, is that neither approach clearly wins on length or quality of life — which means the choice should not be automatic.
How the trial was run
Participants were randomly assigned to one of two paths: preparing for dialysis, or preparing for reactive management, a form of conservative kidney care. They were then tracked over time. The study took nine years in total, seven of which were spent recruiting patients.
Conservative kidney management is an active treatment that simply does not include dialysis, according to Fergus Caskey, professor of nephrology at the University of Bristol's medical school and a consultant urologist at Bristol NHS Foundation Trust. He said the approach is gaining recognition worldwide but that evidence comparing it with dialysis had until now been thin.
Caskey said the findings could have global implications for how kidney failure is handled in older patients who have multiple health conditions or frailty. His conclusion was that someone in that position can weigh both options: preparing for dialysis or conservative management. Each carries advantages and disadvantages, and both are associated with a similar life expectancy and quality of life — so neither should be treated as the standard treatment.
One detail from the trial stands out. Only about one in four participants assigned to prepare for dialysis actually began the treatment. Patients in both groups were more likely to die of other causes than to need dialysis, ConSalud reports.
A decision that needs full information
Fiona Loud, policy director at the UK kidney charity Kidney Care UK, stressed how hard it is to choose a treatment path when living with kidney failure. She said anyone facing that situation must receive all the information, advice and support needed to make a correct and informed decision. According to Loud, the study supplies important evidence that had been missing: data on how to weigh the options when a person is older, frail and living with other health conditions.
Fliss Murtagh, professor and director of the Wolfson Palliative Care Research Centre at Hull York Medical School, said older patients prioritise quality of life, comfort and independence when choosing treatment. She also emphasised that patients need the full picture, good and bad, to decide. In her view, the research provides solid evidence that adults with kidney failure have options delivering practically equivalent outcomes, and the findings should support more personalised care, greater patient choice and better-founded decisions.
What to watch
The study's authors frame the results as a case for shared decision-making rather than a replacement of one treatment with another. How health systems translate that into guidance for older and frail kidney patients — and whether conservative care programmes become more widely available as a result — is the next thing to track.
