Home hemodialysis

Home hemodialysis (HHD), or home hemo, is a form of renal replacement therapy. It is carried out in the home (as opposed to in a hospitalor clinic). Almost without exception, it is for patients with chronic renal failure.

Types of home hemodialysis

There are three basic types of HHD and these are differentiated by the length and frequency of dialysis and the time of day the dialysis is carried out. They are as follows:

  • Conventional home hemodialysis - done three times a week for four hours. It is like in-centre hemodialysis (IHD), but done at home.
  • Short daily home hemodialysis (SDHHD) - done five to seven times a week for approximately two hours per session.
  • Home nocturnal hemodialysis HNHD (also nocturnal home hemodialysis) - done 3.5 to seven times per week at night.

Most of this article focuses on HNHD, as it has become the most popular type of HHD.

Differences between NHHD, SDHHD and IHD

  • Reduced strain on the heart during dialysis - the pump speed in HNHD is lower than in IHD (and SDHHD), 200-300 ml/min versus 300-400 ml/min.
  • Higher clearanceof large and medium-sized molecules (that are diffusion-limited).
  • NHHD and SDHHD treatment regimens provide a higher dialysis dose[{{fullurl:Template:FULLPAGENAME}}#endnote_Greene]; they have a higher a std Kt/Vand HDPthan IHD treatment regimens.
  • NHHD is better than SDHHD, which is better than IHD, at approximating the function of a native kidney.
  • Short dialysis (at home) five times a week is thought to reduce renal osteodystrophy.[{{fullurl:Template:FULLPAGENAME}}#endnote_Bonomini]
  • Large fluid shifts typical in IHD (that can cause nausea and 'wash-out') after dialysis sessions are avoided.

Advantages of nocturnal home hemodialysis

  • Better blood pressuremanagement[{{fullurl:Template:FULLPAGENAME}}#endnote_Chan] - less blood pressure medications.
  • Avoidance of intradialytic hypotension(i.e. low blood pressure during dialysis), something relatively common in IHD.
  • More energy and less 'wash-out' after treatment.
  • Increased fertility - most female ESRD patients treated with IHD stop menstruatingand are infertile. On NHHD, a woman with ESRD managed to get pregnant and have a full-term baby.[{{fullurl:Template:FULLPAGENAME}}#endnote_Gangji]
  • Decreased prevalence of sleep apneaor improvement in severe cases of sleep apnea - sleep better.
  • Less expensive overall for the health system due to lower rates of hospitalization[{{fullurl:Template:FULLPAGENAME}}#endnote_Bergman] and savings on nursing.
  • Total dietary and fluid intake freedom or less dietary restrictions ? e.g. discontinuation of phosphate binders, renal failure food restrictions.[{{fullurl:Template:FULLPAGENAME}}#endnote_Agar]
  • More control over the dialysis treatment schedule and greater life satisfaction.[{{fullurl:Template:FULLPAGENAME}}#endnote_Morris]
  • Live longer.[{{fullurl:Template:FULLPAGENAME}}#endnote_Saner]

Disadvantages of nocturnal home hemodialysis

  • Training is needed (typically six weeks - at which time one is dialysed in-centre)
  • May cause stresses in relationships.
  • Space for the dialysis machine is needed.
  • Alarms from the dialysis machine will occasionally disturb the patient's sleep. Experience from Lynchburg[{{fullurl:Template:FULLPAGENAME}}#endnote_hdc] suggests it happens once every 10 days for people using a fistula and 1-2 times per night if using a catheter.

Barriers to home hemodialysis

Knowledge barriers

  • Lack of awareness amongst patients - most patients with kidney disease in the USA are not informed of home hemodialysis as a treament option for end-stage renal disease. One US study[{{fullurl:Template:FULLPAGENAME}}#endnote_Mehrotra] found that 36% of patients did not have contact with a nephrologist until less than 4 months prior to their first dialysis session and that only 12% of patients were offered home hemodialysis as a treatment option.
  • Lack of training for nephrologists(kidney doctors) - nephrologists in many parts of the world are not trained to treat patients with home hemodialysis. The lack of familiarity with home hemodialysis makes them less likely to offer it to suitable patients.

Patient factors

  • Significant disability - blindness, paralysis.
  • Patient fear of needles/self-canulation.[{{fullurl:Template:FULLPAGENAME}}#endnote_McLaughlin]
  • Patient belief that they will get better care in hospital.[{{fullurl:Template:FULLPAGENAME}}#endnote_McLaughlin]
  • Lack of significant other to assist with HHD.
  • Some clinics require a significant other and require that the significant other is trained.
  • Desire to isolate sickness to hospital - avoid creating a "sick home"

Health care funding models

  • The way doctors are compensated in many jurisdictions is not structured to facilitate/encourage NHHD; in the USA most kidney doctors are not paid for discussing different treatment options with their patients.[{{fullurl:Template:FULLPAGENAME}}#endnote_Mehrotra]
  • Many dialysis providers are for-profit enterprises in the USA and would lose money in the short term from switching to HHD from IHD; HHD requires a large initial capital expenditure, as each HHD patient requires their own dialysis machine and lengthy (expensive) training. Significant savings and benefits (for the society) from HHD are realized in the long-term because of
    1. better health outcomes for patients and lower rates of hospitalization,
    2. higher productivity of ERSD patients (more can hold down steady jobs and contribute to society) and
    3. lower (nursing) labour costs.
Dialysis centres only stand to benefit from (3) (lower nursing costs), as the other costs, as currently structured, are externalizedto society.

History of home hemodialysis

Home hemodialysis started in the early 1960s. Who started it is in dispute. Groups in Boston, London, Seattle[{{fullurl:Template:FULLPAGENAME}}#endnote_Blagg] and Hokkaido all have a claim.

The Hokkaidogroup was slightly ahead of the others, with Nosé's publication of his PhDthesis(in 1962), which described treating patients outside of the hospital for acute renal failuredue to drug overdoses. In 1963, he attempted to publish these cases in the ASAIOJournal but was unsuccessful, which was latter described in the ASAIO Journal when people were invited to write about unconventional/crazy rejected papers.[{{fullurl:Template:FULLPAGENAME}}#endnote_Nose] That these treatments took place in people's homes is hotly disputed by Shaldon[{{fullurl:Template:FULLPAGENAME}}#endnote_Shaldon] and he has accused Nosé of a faulty memory and not being completely honest, as allegendly revealed by some shared Polish Vodka, many years earlier.

The Seattle group started their program in July of 1964. It was inspired by the fifteen year old daughter of a collaborator's friend, who went into renal failure due to lupus erythematosus, and had been denied access to the University Hospital's dialysis centre by their patient selection committee. Dialysis treatment at home was the only alternative and managed to extend her life another four years.

In the September of 1964 the London group (lead by Shaldon) started dialysis treatment at home. In the late 1960s, Shaldon introduced HHD in Germany.[{{fullurl:Template:FULLPAGENAME}}#endnote_Shaldon2004]

Home hemodialysis machines have changed considerably since the inception of the practice. Nosé's machine consisted of a coil (to transport the blood) placed in a household (electric) washing machine filled with dialysate. It did not have a pump and blood transport through the coil was dependent on the patient's heart. The dialysate was circulated by turning on the washing machine (which mixed the dialysate and resulted in some convection) and Nosé's experiments show that this indeed improved the clearance of toxins.

In the USA there has been a large decline in home hemodialysis over the past 30 years. In the early 1970s, approximately 40% of patients used it. Today, it is used by approximately 0.4%.[{{fullurl:Template:FULLPAGENAME}}#endnote_Blagg] In other countries HNHD use is much higher. In Australia approximately 11% of ESRD patients use HNHD.[{{fullurl:Template:FULLPAGENAME}}#endnote_Blagg]

The large decline in HHD seen in the 1970s and early 1980s is due to several factors. It coincides with the introduction and arise of continuous ambulatory peritoneal dialysis(CAPD) in the late 1970s, an increase in the age and the number of comorbidities(degree of "sickness") in the ESRD population, and, in some countries such USA, changes in how dialysis care is funded (which lead to more hospital-based hemodialysis).

Home night-time (nocturnal) hemodialysis was first introduced by Baillod et al. [{{fullurl:Template:FULLPAGENAME}}#endnote_Baillod] in the UKand grew popular in some centres, such as Seattle, but then declined in the 1970s (coinciding with the decline in HHD). Since the early 1990s, NHHD has become more popular again. Uldall [{{fullurl:Template:FULLPAGENAME}}#endnote_Uldall] and Pierratos [{{fullurl:Template:FULLPAGENAME}}#endnote_Pierratos1995][{{fullurl:Template:FULLPAGENAME}}#endnote_Pierratos] started a program in Toronto, which advocated long night-time treatments, (and coined the term 'nocturnal home hemodialysis') and Agar[{{fullurl:Template:FULLPAGENAME}}#endnote_Agar] in Geelongconverted his HHD patients to NHHD.
