Home Dialysis or In Centre: An Honest Comparison

When your kidneys fail, you are choosing between four legitimate paths, not one. In-centre haemodialysis, home haemodialysis, peritoneal dialysis, and conservative care, which treats symptoms actively without dialysis. UK guidance is explicit that everyone likely to need kidney replacement therapy should be offered that whole choice, conservative care included (NICE NG107, 2018).

This is an honest comparison. It includes the parts that sales-brochure versions of home dialysis leave out.

Start with the hard truth

No form of dialysis restores normal kidney function. In the words of the US National Institute of Diabetes and Digestive and Kidney Diseases, haemodialysis "can replace part, but not all" of your kidney function. Three sessions a week of four hours replaces a small fraction of what two healthy kidneys do continuously, every second, without a day off. That is why diet, fluid limits and medicines do not go away when dialysis starts.

Everything below is a trade, not a cure.

In-centre haemodialysis: what you trade

The usual pattern is three sessions a week, about four hours each. Add travel and setting up, and a four-hour session is often a six or seven hour day.

What you get: nurses do the treatment. You do not have to learn anything technical, you do not need a trained partner, you do not need space at home, and problems are picked up by staff who see you three times a week. Many people also value the company, and that is a real benefit, not a consolation prize.

What you pay: this is the least flexible option. Work, family and travel bend around the unit's rota. The three-times-weekly rhythm also means fluid builds up and is then removed in a rush, which is what drives the blood pressure crashes, the cramps and the washed-out feeling afterwards. It carries the tightest fluid and diet restrictions of any option.

Home haemodialysis: what you trade

Home haemodialysis is the same treatment, done by you, with or without a trained partner, on your own schedule. That might be three times a week or every other day for three to five hours, or short daily sessions of two to four hours five to seven days a week, or overnight while you sleep (NIDDK).

What the trials actually showed, honestly. The FHN Daily Trial randomised 245 people to six sessions a week versus three, and found benefit on both of its main outcomes, along with better blood pressure and phosphate control (New England Journal of Medicine, 2010). But it also found an increase in the number of procedures needed on the vascular access. The FHN Nocturnal Trial, in 87 people, found no significant effect on its main outcomes, though blood pressure and phosphate control again improved (Kidney International, 2011).

So the fair summary is this: more frequent dialysis is probably better for how you feel and for several important measurements, the evidence that it makes you live longer is not conclusive, and your access takes more punishment.

Work. In US registry data, employment among people starting dialysis was 9.9% for in-centre haemodialysis, 21% for home haemodialysis and 25% for peritoneal dialysis (USRDS Annual Data Report, 2022). That gap is striking, and it must be read carefully: younger, fitter, more independent people are more likely to be selected for home therapies in the first place. The numbers do not prove that home dialysis keeps you in work. The direction is still plausible, because scheduling control is exactly what a job needs.

What you pay: you or a partner must learn to put needles into your own fistula and run a machine that has your blood in it. Training takes weeks. You need space, storage, and sometimes plumbing or electrical work. And there is the thing people do not say out loud, which is that being alone at home with an alarming machine is frightening until it is not. Emergency procedures have to be rehearsed, not read.

Peritoneal dialysis: a different rhythm entirely

Peritoneal dialysis uses the lining of your own abdomen as the filter. Fluid runs in through a soft catheter, sits there while waste crosses over, then drains out. That is an exchange.

Done by hand, it is at least four exchanges a day, each taking about 30 to 40 minutes, with a dwell of four to six hours or more in between. Done by machine, a cycler does three to five cycles overnight while you sleep, and your days are mostly free (NIDDK).

What you get: no needles. No unit rota. A gentler, continuous treatment with no four-hour rush of fluid removal, so fewer crashes and less post-treatment exhaustion. Your remaining kidney function tends to last longer, which in turn buys you a more liberal diet and fluid allowance. Potassium restriction is usually looser, and some people on peritoneal dialysis need to eat more potassium, not less. It is the easiest modality to travel with.

What you pay: peritonitis is the defining risk, and preventing it means rigorous, unglamorous technique every single time. There is a permanent tube coming out of your abdomen. It is every day, with no day off, and some people find that relentlessness harder than three fixed days. The dialysis fluid contains sugar, which means extra calories, weight gain and blood sugar effects, particularly if you have diabetes. Hernias and leaks happen. Protein is lost into the fluid. And the membrane itself can wear out over years, at which point people move to haemodialysis. Peritoneal dialysis is often not a lifetime modality, and it is kinder to say so at the start.

The catheter should ideally go in at least three weeks before the first exchange, because it works better with time to heal (NIDDK).

Conservative care is a choice, not a defeat

Conservative care means actively treating kidney failure without dialysis: managing anaemia, fluid, itching, nausea, breathlessness and pain, planning ahead, and getting palliative support when it is needed. It is not "doing nothing".

The honest evidence: a meta-analysis of 22 studies and 21,344 patients found dialysis was associated with substantially longer survival, but the people who chose conservative care were a median of 7.0 years older and sicker, and the authors themselves said the results "cannot be translated to an individual level" and must be interpreted cautiously (Nephrology Dialysis Transplantation, 2022). In people aged 80 and over, the survival advantage of dialysis was substantially reduced. Quality of life showed no clear advantage for either path.

Put plainly: for a younger, fitter person, dialysis very probably buys meaningful extra years. For someone very old or frail, it may buy little extra time and will certainly cost time in a hospital chair. That trade is yours to make, and it should be revisited, not decided once and filed.

How to actually choose

Ask what your life is for. Ask who is at home. Ask about your eyesight and your hands. Ask whether you would rather learn something difficult or lose the time. Ask what happens if this choice does not work, because modality is not a life sentence and people move between them.

Then ask your unit for a plan that covers not just what you will do now, but what happens next. Modern access guidance calls this a life-plan for exactly that reason (KDOQI Vascular Access, 2019).

What this means in Seychelles

What is documented in Seychelles is haemodialysis. Peritoneal dialysis is not documented as available anywhere we could verify, and neither is a transplant programme. Across the Indian Ocean islands the same pattern repeats: haemodialysis dominates, peritoneal dialysis is rare or absent, and transplant usually means flying out. Do not assume an option exists locally because it exists in this article. Ask the renal unit.
