AABB Introduces Monthly Platelet and Group O Supply Report

November 17, 2021

AABB is pleased to introduce an interactive report on its Monthly Platelet and Group O Survey to help evaluate the state of the blood supply, with particular regard to platelets and Group O red blood cell components.

The current report is based on data from the June-September 2021 surveys of the AABB institutional member blood centers and hospitals. The data represent approximately 85% of blood collections in the United States. The PDF of the current survey report, instructions to navigate the report and the data use request form are available on the report web page. The survey questionnaire also includes inquiries regarding inventory issues.

Based on the results, there was an increase in total platelet collections by blood collection centers in July compared with June. While the reported increase in platelet collections in the month of August (compared with July) may be attributed to the inclusion of a new blood collection center response, there was a decline in total platelet collections by the blood collection centers between August and September.

The average hospital platelet wastage rate for the months of June through September was 9.3%. Transfusion volumes and wastage rates differ markedly based on hospital characteristics. While approximately 25% of hospitals turned to a secondary supplier to fill their blood needs (majority for 1-4 times/month), only a small fraction of hospitals split platelet units to extend their inventory.

Between June and September, 8-20% of hospitals reported that incomplete RBC orders led either to a delay in patient care or a need to split RBC units to fill transfusion orders; 23-38% of respondents did not track this information. Between 20% and 30% of hospitals reported that incomplete platelet orders led either to a delay in patient care or a need to split platelet units to fill transfusion orders. Between 17% and 35% of respondents did not track this information.

AABB intends to update the data on regular intervals and hopes that, over time, the survey results will evolve and be an important source of data for AABB members and the larger transfusion community. AABB also publishes Group O Blood Supply Report every week to provide estimates of nationwide average Group O supply.
