Abstract
The choice of a dialysis treatment depends on many factors, both medical and non-medical. A full and rational treatment requires easy access to a transplantation programme and to all dialysis modalities, extracorporeal or peritoneal. Presently, haemodialysis (HD) is used almost exclusively for in-centre or limited care treatment, peritoneal dialysis (PD) being preferred for home treatment. On HD, bicarbonate buffer is used in preference to acetate. Mixed convective-diffusive HD techniques have a very limited utilization world-wide because of their cost. Use of PD and automated PD continues to grow, although slowly. In our single-centre experience on a large number of patients, 10-year patient survival is not different on CAPD and HD, and there is initial lower risk of death on CAPD for patients ≥75 years of age. Drop-out from CAPD has increased in recent years, mainly due to the patient/partner ‘bum-out’. Drop-out is less for the elderly, and the difference in modality change between CAPD and RD decreases with increasing patient age, suggesting a clear indication for CAPD in the elderly, or in adults waiting for a transplant. The clinical background, e.g. the presence of diabetes mellitus, cardiovascular disease, dyslipidaemia or obesity, is also important in the choice of method.
