Home hemodialysis is a form of kidney replacement therapy in which hemodialysis is carried out in the patient's home instead of travelling to a dialysis centre for every session. The treatment still follows the same basic principle as in-centre hemodialysis: blood is circulated through a dialysis machine and filter so that waste products and excess fluid can be removed before the blood is returned to the body. What changes is the setting and the way care is organised. Depending on the care model, home hemodialysis may involve trained healthcare professionals, a trained patient or care partner, or a combination of both under nephrologist supervision. Home hemodialysis is not suitable for every patient. Before it is considered, the patient's medical condition, vascular access, home environment, water and electricity requirements, storage, support system and emergency plan all need to be assessed.
What Is Home Hemodialysis?
Home hemodialysis is hemodialysis performed at home using dialysis equipment set up for the patient's prescribed treatment. During treatment, blood leaves the body through the patient's vascular access, passes through a dialyser where waste and excess fluid are removed, and then returns to the body. The treatment prescription - including session frequency, duration, fluid removal and other dialysis parameters - is determined by the nephrologist according to the patient's medical needs. Home dialysis should not be understood as dialysis performed without medical oversight. It requires a defined clinical plan, appropriate equipment, trained people, infection-prevention practices, regular review and a clear pathway for complications or emergencies.
Is Home Hemodialysis the Same as Home Dialysis?
Home dialysis is a broader term that can refer to more than one form of dialysis performed outside a dialysis centre. Two main types may be discussed: They use different methods, equipment and care routines. A patient should follow the dialysis modality recommended by the nephrologist rather than assuming that the two approaches are interchangeable.
- Home hemodialysis, where blood is filtered through a hemodialysis machine
- Peritoneal dialysis, where the lining of the abdomen is used as the dialysis membrane
How Does Hemodialysis at Home Work?
- Pre-dialysis assessment
- Machine and consumable preparation
- Vascular-access care
- Dialysis treatment according to the prescription
- Monitoring during dialysis
- Management of alarms or complications
- Post-dialysis assessment
- Cleaning, waste handling and documentation
1. Pre-Dialysis Assessment
- Weight
- Blood pressure
- Pulse
- Temperature where required
- Symptoms such as breathlessness, swelling, dizziness or fever
- The condition of the vascular access
2. The Dialysis Machine and Dialyser
A hemodialysis machine controls the movement of blood and dialysis fluid during treatment and monitors several safety parameters while the session is running. A dialyser, sometimes called an artificial kidney, contains a membrane that helps remove waste products and excess fluid from the blood. The machine, dialyser and other components used at home should be suitable for the prescribed home-dialysis programme and supported by an appropriate maintenance and service plan.
3. Vascular Access
Hemodialysis requires reliable access to the bloodstream. Depending on the patient, vascular access may involve: The type of access, how it is used and who is permitted to handle it should be determined by the treating dialysis team. Vascular-access care is a major safety component of home hemodialysis because infection, bleeding, clotting or access malfunction may interrupt treatment or require urgent medical review.
- An arteriovenous fistula
- An arteriovenous graft
- A dialysis catheter where clinically required
4. Monitoring During Dialysis
- Blood pressure
- Pulse
- Symptoms
- Machine alarms and treatment parameters
- The vascular access and blood lines
5. Post-Dialysis Care
- Post-dialysis weight
- Blood pressure and pulse
- Assessment for dizziness, cramps, weakness or other symptoms
- Vascular-access care
- Documentation of the completed treatment
Who May Be Suitable for Home Hemodialysis?

- Emergency access to medical care
Who May Not Be Suitable for Home Hemodialysis?
- The patient is clinically unstable
- Dialysis frequently causes significant complications requiring facility-based intervention
- Vascular access is unsuitable or has unresolved problems
- Required water, electricity or drainage arrangements cannot be provided
- There is not enough clean space for equipment and supplies
- Required trained support is unavailable
- Emergency transfer would be impractical
- The nephrologist recommends centre- or hospital-based dialysis
What Does a Home Hemodialysis Setup Require?
- A suitable dialysis machine
- Dialyser and prescribed consumables
- A clean treatment area
- Suitable water treatment where required by the equipment
- Reliable electricity
- Appropriate drainage
- Storage for consumables and medicines
- Infection-prevention supplies
- Waste-disposal arrangements
- Monitoring equipment as prescribed
- Emergency and backup planning
6. Space Requirements
- Easy cleaning
- Safe cable and tubing placement
- Storage
- Access to water, electricity and drainage where required
- A clear route for emergency access
7. Water Requirements
Many home hemodialysis systems require treated water to prepare dialysis fluid. The water source and treatment system must meet the requirements of the specific equipment and dialysis programme. Before installation, the team should assess: Families should not assume that normal household tap water can be connected directly to a dialysis machine without an approved treatment system.
- Incoming water supply
- Water pressure and plumbing requirements
- Water-treatment equipment where required
- Drainage
- Maintenance and testing responsibilities
8. Electricity Requirements
- Power requirements of the dialysis machine
- Power requirements of water-treatment equipment where used
- Appropriate electrical outlets and earthing
- Whether a dedicated circuit is required
- What backup power is needed
- What happens if a power cut occurs during treatment
9. Storage for Dialysis Supplies
Home hemodialysis can require a regular supply of dialysers, blood-line sets, needles or catheter-related supplies, disinfectants, dressings and other consumables. The home should have a clean, dry and organised storage area that keeps supplies protected and easy to monitor. A replenishment process should be established so that clinically important supplies do not run out before the next scheduled delivery.
How Often Is Home Hemodialysis Done?
There is no single schedule for every home hemodialysis patient. Frequency and duration depend on the nephrologist's prescription, the patient's medical condition, dialysis goals, equipment and the home-dialysis programme. Different programmes may use different schedules, including conventional or more frequent dialysis approaches. Patients should not change session frequency, duration or fluid-removal targets without nephrologist guidance.
What Are the Potential Advantages of Home Hemodialysis?
For suitable patients, home hemodialysis can reduce the need to travel to a dialysis centre for every treatment and may allow care to be organised around the home environment. Potential practical advantages may include: The clinical benefits and risks depend on the individual patient and dialysis prescription. Families should not assume that home dialysis is automatically better than centre-based dialysis.
- Less routine travel to a dialysis centre
- A familiar treatment environment
- Greater scheduling flexibility within the prescribed programme
- Closer integration of dialysis with home-based care for medically dependent patients
- Potentially easier coordination for patients with major mobility limitations
What Are the Challenges of Home Hemodialysis?
- Preparing the home infrastructure
- Managing supplies and storage
- Ensuring reliable water and power
- Training and competency requirements
- Vascular-access care
- Handling machine alarms
- Maintaining infection-prevention routines
- Emergency planning
- Coordinating regular nephrology follow-up and investigations
What Are the Main Risks During Home Hemodialysis?
- Low blood pressure
- Dizziness or weakness
- Muscle cramps
- Bleeding from vascular access
- Access infection or malfunction
- Clotting in the dialysis circuit
- Machine or water-system alarms
- Problems related to fluid removal
- Other patient-specific complications
10. Vascular-Access Safety
- Who may connect and disconnect the access
- How the access is checked before dialysis
- How bleeding is managed after treatment
- Which signs suggest infection or access malfunction
- Who should be contacted if the access cannot be used
11. Infection Prevention
- Hand hygiene
- Cleaning the treatment area
- Aseptic handling of vascular access according to the prescribed protocol
- Correct storage of consumables
- Device cleaning and disinfection according to manufacturer and programme instructions
- Appropriate waste handling
12. What Happens if There Is a Power Cut?
The home-dialysis plan should define what happens if electricity is interrupted during treatment. The response depends on the specific dialysis equipment and treatment stage, so families should receive device-specific instructions from the dialysis team. Before treatment begins at home, the plan should clarify:
- Whether backup power is required
- What backup system is appropriate for the actual equipment
- What the machine does when mains power fails
- Who to contact if treatment cannot continue
- When medical review or hospital transfer is required
13. What Happens if the Water Supply Fails?
If the dialysis system depends on a continuous water supply and water treatment, an interruption can prevent treatment from proceeding normally. The home programme should define how water problems are identified, whom to contact and whether the session needs to be delayed, stopped or moved to an alternative dialysis setting. Families should not improvise alternative water connections or bypass prescribed water-treatment systems.
14. What Happens if the Dialysis Machine Develops a Fault?
- Which alarms trained users may respond to
- Which alarms require immediate technical or clinical help
- How technical support is contacted
- What backup dialysis arrangement exists if the machine cannot be used
- When the patient should receive dialysis at a centre or hospital instead
Training for Home Hemodialysis
Training requirements depend on the home-dialysis model. Where patients or care partners participate directly in treatment, training may cover: In professionally supported home hemodialysis, trained healthcare staff may perform many or all of these tasks. Families should understand exactly what is expected from them.
- Preparing the treatment area
- Hand hygiene and infection prevention
- Machine preparation
- Vascular-access procedures appropriate to the programme
