Effects of a hospital-wide introduction of a massive transfusion protocol on blood product ratio and blood product waste.

Background: Massive transfusion protocols (MTPs) are increasingly used in the transfusion practice and are developed to provide the standardized and early delivery of blood products and procoagulant agents and to supply the transfusion of blood products in a well-balanced ratio.

Aim: The aim of this study was to investigate the effect of a hospital-wide introduction of an MTP on blood product ratio and a waste of blood products.

Materials And Methods: Retrospective analysis was performed to compare the transfusion practice in massive bleeding patients before and after the introduction of an MTP and between the use of an MTP and transfusion off-protocol.
