Blood consumption in the Role 2 setting: A Department of Defense Trauma Registry analysis. | LitMetric

AI Article Synopsis

  • The Role 2 setting is the most forward military treatment facility, which has limited surgical and holding capabilities, and there's a lack of data on blood product use in such environments.* -
  • A study analyzed data from the Department of Defense Trauma Registry between 2007 and 2023, focusing on blood product consumption in 15,581 medical encounters at Role 2 facilities.* -
  • Results showed that while only a small percentage of patients received significant transfusions, the amounts consumed could exceed current supply recommendations, indicating a need for better blood resupply strategies in future conflicts.*

Article Abstract

Background: The Role 2 setting represents the most far-forward military treatment facility with limited surgical and holding capabilities. There are limited data to guide recommendations on blood product utilization at the Role 2. We describe the consumption of blood products in this setting.

Study Design And Methods: We analyzed data from 2007 to 2023 from the Department of Defense Trauma Registry (DODTR) that received care at a Role 2. We used descriptive and inferential statistics to characterize the volumes of blood products consumed in this setting. We also performed a secondary analysis of US military, Coalition, and US contractor personnel.

Results: Within our initial cohort analysis of 15,581 encounters, 17% (2636) received at least one unit of PRBCs or whole blood, of which 11% received a submassive transfusion, 4% received a massive transfusion, and 1% received a supermassive transfusion. There were 6402 encounters that met inclusion for our secondary analysis. With this group, 5% received a submassive transfusion, 2% received a massive transfusion, and 1% received a supermassive transfusion.

Conclusions: We described volumes of blood products consumed at the Role 2 during recent conflicts. The maximum number of units consumed among survivors exceeds currently recommended available blood supply. Our findings suggest that rapid resupply and cold-stored chain demands may be higher than anticipated in future conflicts.
