About this trial

Traumatic injuries affect people of all ages, races, and socioeconomic backgrounds. The Global Burden of Disease study showed that globally in 2019, there were more than 4.4 million deaths due to injury. Furthermore, unintentional injuries are the leading cause of death for people aged 5-29 years worldwide. Uncontrolled bleeding accounts for a significant proportion of these deaths, with approximately 20% occurring in the first 24 hours and 40% occurring within the first 30 days.

Blood transfusion is a life-saving treatment in the management of bleeding patients until bleeding is controlled in hospital, typically delivered through different blood components (red blood cells, plasma and platelets). These components are derived from a whole blood donation and are stored in separate bags (units). There are challenges in carrying separate blood products, such as additional weight in kit bags, and transfusing multiple blood products at the scene can delay transport to hospital.

In Ontario, Ornge Air Ambulance carries red blood cells and plasma to transfuse prehospital. However, a prehospital transfusion strategy has not been established and practice varies across the Canadian setting, and more broadly across the world.

This trial aims to investigate if carrying and transfusing two units of whole blood instead of four units (two red blood cells and two plasma) is feasible and leads to better outcomes for patients.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Patient who has suffered a traumatic injury

Knowledge that patient will object to being given blood transfusion for any reasons

Blood already administered on-scene, prior to arrival of the participating Ornge AAS

Trial outcomes

Primary outcomes

1

Proportion of patients enrolled in the study that receive a prehospital transfusion and had full study data collected

Feasibility target: \>90% patients enrolled were able to link prehospital to in-hospital records and \>90% complete data obtained

Time frame
through study completion, up to 90 days
2

Number of patients that completed transfusion of at least 1 unit of assigned blood products prior to arrival to receiving lead trauma hospital

Feasibility target: at least 1 unit of blood \[WB, RBC, or plasma\] transfused prior to arrival \>90% of the time

Time frame
Enrolment to day 1 after enrolment
3

Number of patients that completed transfusion of all assigned blood products at the receiving lead trauma hospital

Feasibility target: \>90% if not already done prior to arrival of hospital

Time frame
Enrolment to day 1 after enrolment
4

Number of patients screened for the study by not randomized due to lack of group O negative WB availability.

Time frame
through study completion, an average of 1 year

Secondary outcomes

1

Death or Massive Transfusion at 24hrs

To determine the impact of prehospital administration of WB on the proportion of participants who experience death or massive transfusion at 24 hours, compared to the current standard of care (component blood therapy).

Time frame
through study completion, up to 90 days
2

Mortality - 90 days

To determine the impact on mortality up to 90 days.

Time frame
through study completion, up to 90 days
3

Mortality - 30 days

To determine the impact on morbidity up to 30 days.

Time frame
through study completion, up to 90 days
4

Organ Failure Free Days

Time frame
through study completion, up to 90 days
