Hemodialysis product

Hemodialysis product (HDP) - is a number used to quantify hemodialysis and peritoneal dialysis treatment adequacy.

It was proposed by Scribner and Oreopoulous because of their perceived inadequacy of the Kt/V measure of dialysis adequacy. It has not been widely adopted.

The HDP is defined by the following empirical formula:


 * HDP = t * f 2

Where:
 * HDP - hemodialysis product
 * t - dialysis time (hours/dialysis session)
 * f - dialysis frequency (dialysis sessions/week)

The formula, like all empirical formulae, has no theoretical basis. The HDP has not seen widespread use.
