Improving adequacy improves haemodialysis outcome.

Our goal of maintenance dialysis for the coming millennium is optimal rather than just adequate dialysis. Delivering a large amount of dialysis expressed in terms of urea Kt/V is a necessary but insufficient measure to improve clinical outcome. Cardiovascular morbidity and mortality remain very high in haemodialysis. This is due in great part to the insufficient control of extra cellular volume and blood pressure. Ours, as well as published data, indicate that up to now, only increasing dialysis time either by prolonging the session or increasing its frequency has proven value in overcoming this critical issue.
