- Time to hemorrhage control is critical, as mortality in patients with severe hemorrhage that arrive to trauma centers with sign of life remains over 40%. Prompt identification and management of severe hemorrhage is paramount to reducing mortality. In traditional US trauma systems, the early hospital course of a severely hemorrhaging patient typically proceeds from the trauma resuscitation bay to the operating room or angiography suite with a potential stop for radiological imaging. This protracted journey can prove fatal as it consumes valuable minutes. In contrast to the current US system is a newly developed and increasingly adopted system in Japan called the hybrid emergency room system (HERS). The hybrid ER is equipped to allow resuscitation, imaging, and damage control intervention to occur in the ER without the need to transport the patient to a subsequent destination. The HERS is relatively new and remains restricted to a small number of institutions, limiting the ability to robustly examine impact(s) on patient outcomes. Even if proven to yield superior outcomes, there are significant obstacles to adopting the HERS in the US. Challenges such as the high cost of building and implementing a HER system, return on investment, and the significant differences between the US and Japan in terms of physician training, trauma center, and reimbursement schemes may render the hybrid ER system to be unfeasible in most current trauma centers. Barriers aside, the Japanese hybrid ER system remains the most novel recent advancement in the quest to reduce potentially preventable mortality from hemorrhage.

Limitations of Available Blood Products for Massive Transfusion During Mass Casualty Events at us Level 1 Trauma Centers

- INTRODUCTION: Exsanguination remains a leading cause of preventable death in traumatically injured patients. To better treat hemorrhagic shock, hospitals have adopted massive transfusion protocols (MTPs) which accelerate the delivery of blood products to patients. There has been an increase in mass casualty events (MCE) worldwide over the past two decades. These events can overwhelm a responding hospital's supply of blood products. Using a computerized model, this study investigated the ability of US trauma centers (TCs) to meet the blood product requirements of MCEs.METHODS: Cross-sectional survey data of on-hand blood products were collected from 16 US level-1 TCs. A discrete event simulation model of a TC was developed based on historic data of blood product consumption during MCEs. Each hospital's blood bank was evaluated across increasingly more demanding MCEs using modern MTPs to guide resuscitation efforts in massive transfusion (MT) patients.RESULTS: A total of 9,000 simulations were performed on each TC's data. Under the least demanding MCE scenario, the median size MCE in which TCs failed to adequately meet blood product demand was 50 patients (IQR 20-90), considering platelets. 10 TCs exhaust their supply of platelets prior to RBCs or plasma. Disregarding platelets, five TCs exhausted their supply of O- packed red blood cells (RBCs), six exhausted their AB plasma supply, and five had a mixed exhaustion picture.CONCLUSION: Assuming a TC's ability to treat patients is limited only by their supply of blood products, US level-1 TCs lack the on-hand blood products required to adequately treat patients following a MCE. Use of non-traditional blood products, that have a longer shelf life, may allow TCs to better meet the blood product requirement needs of patients following larger MCEs.
