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.
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. An Egyptian study published in 2011 found that HDP is "a valid test with high sensitivity and specificity for assessment of adequacy of hemodialysis in comparison to KT/V and URR."
Famous quotes containing the word product:
“Perhaps I am still very much of an American. That is to say, naïve, optimistic, gullible.... In the eyes of a European, what am I but an American to the core, an American who exposes his Americanism like a sore. Like it or not, I am a product of this land of plenty, a believer in superabundance, a believer in miracles.”
—Henry Miller (1891–1980)
