I was asked to look into our expected values for quality performance for such things as QNS rate, double venipuncture rate, donor adverse reaction rate, apheresis patient adverse reaction rate, and repeatedly reactive transmissible disease tests. Currently we use the following expected rates, to evaluate quality performance: QNS rate: 2% Double venipuncture rate: 5% Donor adverse reaction rate: 5% Apheresis patient adverse reaction rate: 5% Repeatedly reactive test results: unknown? (I guess I am just looking for an overall prevelance of RR test results in the blood donor pool to compare our rate to) I am unaware of where these numbers first came from. What I am wondering is, does anyone know what resource lists expected quality performance numbers for the things listed above? And further, what numbers are used at your facilities as expected quality performance? If anyone has an answers please post or drop me a PM please. Thank you. p.s. I guess I should add that our donors include both homologous and autologous donors.
