Dialysis time: what you prescribe is what you get? (WYPIWYG).

The duration of a dialysis session is an essential parameter in determining dialysis efficiency and hence adequacy. The aim of this study was to measure the real dialysis time and to compare it to the prescribed time. For 12 months, 8412 dialysis treatments were allocated a number and a random sample of 100 was selected using a computer generated randomisation code.
