Dialysis at Home: PD, Home Hemodialysis & What to Expect

Peritoneal dialysis (PD)

PD uses the peritoneum — the membrane lining your abdomen — as a natural filter. A sterile solution is infused through a catheter into the abdomen, wastes and fluid pass into it over several hours, then it's drained. No needles, no blood circuit, no machine dependence for the manual version.

Two PD styles: CAPD (continuous ambulatory PD — 4-5 manual exchanges daily) and APD (automated PD — a machine cycles fluid overnight while you sleep). APD is the most common modern choice. Training takes 1-2 weeks; many patients manage PD alone without a partner.

PD preserves residual kidney function better than hemodialysis in the first years, offers a more flexible diet, and is the preferred home option for many — but it requires catheter care discipline and daily commitment.

Home hemodialysis

Home hemodialysis uses the same blood-cleaning technology as in-center, at home. Sessions can be conventional (3-4×/week), frequent (5-6×/week, shorter), or nocturnal (overnight, 6-8 hours). More frequent sessions improve blood pressure control, phosphate removal, and can allow dietary and medication freedom.

Requirements: a care partner (for safety), ~4-8 weeks of training at your center, a dedicated space for the machine, and water access. Medicare covers the machine, supplies, training, and a monthly clinic visit.

The FHN trials showed frequent home HD improves left-ventricular mass, blood pressure, and quality of life. Nocturnal HD is associated with fewer hospitalizations in registry analyses.

Who qualifies for home dialysis?

Most stable dialysis patients are candidates. The medical eligibility is broad — age alone is not a barrier; many centers train patients into their 70s. What matters: ability to learn the procedures, adequate vision and hand function, stable housing with space (especially for home HD), and — for home HD — a willing care partner.

Not candidates: patients with severe cognitive impairment without support, unstable housing, or those who cannot be trained. PD has additional medical considerations: prior major abdominal surgery, extensive adhesions, or hernias need evaluation.

The honest conversation: home dialysis requires discipline and ownership of your treatment. For patients who want independence and can manage it, it's often the best choice — for those who prefer staff support and routine, in-center is valid.

Outcomes and evidence

Registry data (USRDS) show home modalities have survival at least equal to in-center hemodialysis, with lower hospitalization rates. The FHN frequent-dialysis trial (NEJM 2010) found frequent home HD improved cardiac structure and blood pressure. PD patients typically report higher quality-of-life scores and employment rates.

The key caveat: outcomes depend on adherence. PD peritonitis (preventable with hygiene discipline) and home HD access problems are the failure modes — both manageable with good training and support programs.

Costs and coverage

Medicare Part B covers home dialysis: training, the machine, all supplies, physician oversight, and support staff visits. Patients with Original Medicare plus Medigap typically face minimal out-of-pocket costs beyond premiums.

System cost: home therapies run roughly 15-30% less per year than in-center (lower facility overhead). For patients, home dialysis also saves travel time and co-pay trips to the clinic.

Talk to your center about home programs early — even before dialysis starts. Pre-dialysis education about all modalities (including home options) is a KDIGO-recommended standard that improves outcomes.
