title: Home haemodialysis dose: how much of a good thing?
abstract: BACKGROUND
  Home dialysis (peritoneal or haemodialysis) in any reasonable guise offers potential benefits compared with in-centre dialysis. Benefits may be overtly patient centred (independence, quality of life), outcome oriented (survival, resolution of left ventricular hypertrophy) or resource friendly (savings on staff costs). The priority placed on each of these areas is likely to vary from patient to patient, and possibly provider to provider. This is the one strength of home haemodialysis (HHD) rather than being viewed as a weakness, as it can offer different benefits to different people. Intuitively, more haemodialysis is better than less, and this is most realistically achieved at home. Indications are that both long nocturnal dialysis and short daily dialysis can offer real objective benefits.
  
  
  METHODS
  Critics argue correctly that there is a paucity of robust randomised controlled study data. The complexity of HHD regimens and practice and in-homogeneity of patients means such firm data are unlikely to be forthcoming. However, the positive reports both subjective and objective of patients dialysing at home, and results from the available research suggest that advantages may be seen purely with changing the location of dialysis to home, and independently with enhancing dialysis schedules.
  
  
  CONCLUSIONS
  The logical conclusion is that patients undertaking haemodialysis at home should have at least the recommended minimum of four hours three times per week (or equivalent), preferably avoiding the long inter-dialytic interval, but beyond that rigid adherence to a schedule as dogma should be subjugated to patient choice and flexibility, albeit by prior agreement with supervising medical and nursing staff.
