Temperature mapping in an air ambulance helicopter: Implications for the delivery of pre-hospital transfusion

Prehospital Trauma Compendium: Transfusion of Blood Products in Trauma - A Position Statement and Resource Document of NAEMSP

Hemorrhagic shock remains the leading cause of potentially preventable death among injured patients with life-threatening bleeding. Prehospital resuscitation has been evolving with increasing use of blood product resuscitation. The impact of blood administration on patient outcomes remains poorly defined with significant heterogeneity in the quality of literature supporting prehospital blood product resuscitation after trauma. We completed a structured search of the literature using a rapid review framework based on three distinct PICO questions to develop systematic and consensus recommendations.

The National Association of Emergency Medical Services Physicians (NAEMSP) recommends, in EMS agencies/systems that can support a high-quality prehospital blood transfusion program:Use of blood components over crystalloids for the first-line treatment of patients with traumatic life-threatening bleeding in the prehospital phase of resuscitationUse of low titer group O whole blood (LTOWB) as the first-choice blood product for treatment of patients with traumatic life-threatening bleeding in the prehospital phase of resuscitationUse of a combination or composite of prehospital transfusion indications, focused on physiologic abnormalities and/or injury patterns with obvious significant blood loss.Use of active monitoring for transfusion-related adverse events.Developing a mechanism to recycle unused blood product units nearing their expiration date to a high-use hospital facility to minimize wastage.Engaging in a comprehensive longitudinal active collaboration between EMS agencies, trauma centers, and blood suppliers to ensure the success of a prehospital transfusion program.

Process Mining Uncovers Actionable Patterns of Red Blood Cell Unit Wastage in a Health Care Network

Packed red blood cell transfusions are integral to the care of the critically and chronically ill patient, but require careful storage and a large, coordinated network to ensure their integrity during distribution and administration. Auditing a Transfusion Medicine service can be challenging due to the complexity of this network. Process mining is an analytical technique that allows for the identification of high-efficiency pathways through a network, as well as areas of challenge for targeted innovation. Here, we detail a case study of an efficiency audit of the Transfusion Medicine service of the Nova Scotia Health Administration Central Zone using process mining, across a period encompassing years prior to, during, and after the acute COVID-19 pandemic. Service efficiency from a product wastage perspective was consistently demonstrated at benchmarks near globally published optima. Furthermore, we detail key areas of continued challenge in product wastage, and suggest potential strategies for further targeted optimization.
