Shared surgery blood reserve reduces surgery suspension rate due to blood unavailability.

The hemotherapy service in health units with high surgical demand has been pointed out as a challenge, especially concerning storage management simultaneously with transfusion demand attendance. The objective of this study is to analyze service efficacy after the implementation of a new strategy to meet storage and transfusion demands. The present study analyzed the records of the hemotherapy service related to blood components management in surgeries where blood reserve was necessary for RhD positive patients at the National Institute of Traumatology and Orthopedics. A shared compatibility test and surgery reserve from the first semester of 2018 was compared to an equivalent period in 2017, prior to its implementation, under an individualized protocol to each patient scheduled on the surgery map. After the implementation of the shared protocol, the transfusion demand was higher, due to an increase in the percentage of surgeries that required transfusion, as well as to the augmented number of blood components used in the surgeries. Even in the presence of a slight decrease in storage, the hemotherapy assistance was considered efficient, since the percentage of surgery suspension reduced from 2 % to 0.2 % after the implementation of the shared protocol. This improvement resulted in an adjustment in the classification of reasons for surgical procedure cancellations, so that the reason "blood shortage" was repositioned from the first to the seventeenth position. This is the first record of a shared compatibility protocol and surgery reserve and we hope to contribute to the development of the hemotherapy service and surgical patient healthcare.
