Can patients choose which dialysis type they use? 

In most cases, patients in the UK have a significant say in choosing which type of dialysis they use. While the final decision is made in consultation with a renal (kidney) team, the NHS and NICE guidelines emphasise ‘shared decision-making’, where your lifestyle, home environment, and personal preferences are balanced against your clinical needs. If there are no specific medical reasons why one method would be unsafe, the choice is usually yours. 

What We’ll Discuss in This Article 

• The principle of shared decision-making in the UK renal care system 

• Clinical factors that might limit your choice of dialysis 

• How lifestyle factors like work, travel, and housing influence the decision 

• The role of the multi-disciplinary team in helping you choose 

• Why some patients are better suited for home-based vs hospital-based care 

• The possibility of switching dialysis types if your circumstances change 

The patient’s right to choose their dialysis method 

Under NHS guidelines, you should be offered a choice between haemodialysis (either in a hospital or at home) and peritoneal dialysis, provided both are clinically appropriate for you. This choice is part of a process called ‘Shared Decision Making’, where your doctor provides the medical evidence, and you provide the expertise on your own life. You will typically be given a period of education where you meet with specialist nurses to discuss how each method would impact your daily routine. 

The goal of this choice is to ensure that the treatment fits into your life, rather than your life revolving entirely around the treatment. For many, this means choosing the method that allows them to continue working or caring for family. However, if a specific medical condition makes one type of dialysis dangerous for you, your consultant will explain why that option is not recommended. 

Clinical factors that may influence the final decision 

While patient preference is a priority, certain medical conditions can make one form of dialysis more effective or safer than the other. For instance, peritoneal dialysis requires a healthy abdominal lining (peritoneum). If you have had major abdominal surgery in the past that resulted in significant scarring or adhesions, this method might not work effectively for you. Similarly, if you have certain types of hernias or inflammatory bowel disease, peritoneal dialysis might be discouraged. 

Haemodialysis also has specific clinical requirements, primarily related to your cardiovascular health and vascular access. To perform haemodialysis, a surgeon needs to create an arteriovenous fistula (a joined vein and artery). If your blood vessels are very small or damaged, creating this access point might be difficult. Additionally, the rapid fluid shifts in haemodialysis can sometimes put a strain on a weak heart, which might make peritoneal dialysis a gentler, more appropriate alternative. 

Comparing choice factors: Haemodialysis vs Peritoneal Dialysis 

The following table outlines the common reasons why a patient might choose one method over the other: 

Factor	May Favour Haemodialysis	May Favour Peritoneal Dialysis
Independence	Prefer medical staff to manage care	Prefer to manage care independently
Social Contact	Enjoy interacting with other patients	Prefer the privacy of home
Home Space	Limited space for equipment storage	Sufficient space for boxes of fluid
Needle Phobia	Willing to tolerate needles	Strongly prefer a needle-free option
Flexibility	Prefer having 4 ‘off’ days a week	Prefer daily, flexible scheduling
Physical Ability	May have difficulty handling equipment	Able to perform manual tasks safely

Causes for needing a dialysis choice 

The need for a dialysis choice arises when a patient reaches stage 5 chronic kidney disease, also known as end-stage renal failure. At this stage, the kidneys are functioning at less than 15 per cent of their normal capacity. Common causes leading to this stage include long-term diabetes, chronic high blood pressure, and glomerulonephritis. Because these conditions are often managed over many years, patients usually have time to discuss their dialysis options before they actually need to start treatment. 

The National Institute for Health and Care Excellence (NICE) recommends that these discussions begin well in advance. This ‘pre-dialysis’ phase is crucial because it allows for the surgical preparation of the chosen access site (the fistula for haemodialysis or the catheter for peritoneal dialysis) to heal properly before it is needed. 

Triggers that might change your dialysis choice 

A dialysis choice is not necessarily permanent. There are several triggers that might cause a patient to switch from one type to another. One of the most common triggers is the loss of ‘residual kidney function’. Peritoneal dialysis is often very effective while the kidneys still produce some urine, but as that function stops completely, some patients find they feel better switching to haemodialysis. 

Infections can also be a trigger. Recurrent peritonitis (infection of the abdominal lining) can damage the peritoneum, making peritoneal dialysis less effective. On the other hand, if a patient on haemodialysis has repeated problems with their fistula or vascular access, they may be advised to switch to peritoneal dialysis. Lifestyle changes, such as a change in housing or a new job, are also valid reasons to revisit the choice with your renal team. 

Differentiation: Home vs Hospital-based choices 

A key part of the choice is deciding where the treatment happens. In the UK, haemodialysis can be done in a hospital unit or at home. Peritoneal dialysis is almost always done at home. Choosing a home-based therapy requires a degree of confidence and a suitable environment, but it offers the greatest level of freedom. 

If you choose hospital-based haemodialysis, you will have the reassurance of being monitored by nurses and doctors throughout the procedure. This is often the preferred choice for patients who live alone and feel anxious about managing a machine themselves, or for those who have other complex health conditions that require close supervision. 

My Final Conclusion 

Ultimately, the choice of dialysis is a collaborative effort between you and your healthcare team. While medical safety is the priority, the NHS is committed to providing the treatment that best supports your quality of life. By understanding the pros and cons of each method, you can make an informed decision that aligns with your personal goals and health needs. 

If you experience severe, sudden, or worsening symptoms, such as sudden breathlessness, chest pain, or severe confusion, call 999 immediately.
