Data on apheresis, blood collection, and transfusion‐related activities: statistical analyses of the American Association of Blood Banks institutional membership questionnaires

Abstract

Ongoing data analysis of the institutional questionnaires provides information on trends in blood collection and transfusion-related activities.

Wound‐healing properties of trehalose‐stabilized freeze‐dried outdated platelets

“…22 In addition, there is considerable waste of 5-or 7-day RT-PLTs because of inability to accurately predict demand, the time needed for preparation, and infectious disease testing. 23 As a result a significant number of outdated units are discarded every year making PLTs expensive to process and maintain. Even though overproduction occurs the short shelf life and unpredictable need has resulted in annual shortages.…”

Variation of platelet production and discard rates in 17 blood centers representing 10 European countries from 2000 to 2002

“…This may partly explain why all blood centers except two in this study produced PLTs by two methods to enhance their responsiveness. PLT products are short‐aged for various reasons, and outdating has been considered the main reason for discarded PLTs 10,12 , 22,24 , 26 . Much effort has been directed to developing methods to allow prolonged PLT storage, such as new preservation solutions, cold storage, 27 and the implementation of bacterial screening followed by extended shelf life 7,8 , 10,28 .…”

“…Blood component preparation processes vary not only between but within countries 12,13 . Only a few studies on component preparation have been published from different countries or even at the national level 14‐16 .…”

Platelet Concentrates from Automated Apheresis – Past, Present and Future Developments

“…Therefore, in the USA the use of APC increased by 34% between 1987 and 1989 [44] and by 50% between 1989 and 1991. In 1990 30-40% of the therapeutical doses of PC derived from apheresis [45]. In Germany, 50% of all transfused platelets in 1996 were APC [46].…”
