This information is not collected centrally. There is no specific waiting list for dialysis. Dialysis is often an emergency treatment and patients with no kidney function will die in a matter of weeks if they do not receive dialysis. For patients whose disease has been identified well in advance of end-stage renal failure, dialysis begins at a time when the individual and his or her consultant feel it is appropriate. Part one of the national service framework for renal services recommends starting to prepare people for dialysis about a year before it will be needed, as such preparation leads to better outcomes for the patient.
