Effect of continuous ambulatory peritoneal dialysis on a British renal unit.

Experience in the use of continuous ambulatory peritoneal dialysis (CAPD) for the treatment of end stage renal failure in Nottingham was reviewed. During six years 150 patients aged from 11 to 73 received this type of treatment. At three years patient actuarial survival was 69% and CAPD technique survival was 41%. Although CAPD was satisfactory as a first treatment for many patients, its long term use was possible in only a few. Actuarial survival of patients who changed to haemodialysis was 64% at one year after the change, suggesting that unsuccessful CAPD increased the risk of death. Hospital haemodialysis was the only suitable form of treatment for most patients in whom CAPD had been abandoned. British renal units have adopted CAPD to a much greater extent than those in Europe, but care in the selection of patients is necessary to reduce mortality, and many patients may eventually need hospital haemodialysis. Greater numbers of hospital haemodialysis places will probably have to be made available to meet this extra demand.
