Multicenter analysis of massive transfusion practices demonstrates variabilities across trauma centers in the Southwestern Surgical Congress.

Background: This study's purpose is to investigate emergent blood (EB) usage, massive transfusion protocols (MTP), and the use of pharmacologic adjuncts to resuscitation across trauma centers in the Southwestern Surgical Congress (SWSC).

Methods: Anonymous, voluntary 26-question survey conducted by the SWSC multicenter trials group. Descriptive statistical analysis was performed.

Results: 36 institutions across 14 states responded. EB is immediately available at 27 institutions. 53 ​% have LTOWB available. LTOWB is incorporated into MTP at 39 ​% of institutions and is the primary MTP product used at 4 centers. 65 ​% of institutions use thromboelastography to guide resuscitation. 70 ​% of institutions reported using TXA and 11 ​% used fibrinogen concentrate. 36 ​% of responding institutions routinely draw ionized calcium values. Four institutions have a calcium replacement protocol. Only 6 centers report redosing antibiotics during MTP.

Conclusion: EB availability and MTP practices are evolving with variability across the SWSC. Pharmacologic therapies remain poorly incorporated into the MTP.
