Does CAPD guarantee adequate dialysis delivery and nutrition

Despite the vast experience gained over 15 years of CAPD practice there is growing concern about the long-term viability of this therapy and its ability to deliver sufficient dialysis to maintain patient well-being and survival [1]. With reduction in peritonitis and the subsequent improvement in technique survival the issue of long-term dialysis adequacy becomes increasingly important. The purpose of this editorial is to evaluate normalized clearance as a measure of dialysis adequacy, and the nature of the relationship between dialysis dose and nutrition. Is it possible to determine the priorities in optimizing CAPD therapy?
