Point of Care Fibrinogen Measurement in Trauma Patients in the Emergency Department

Netherlands150 participantsStarted 2025-11-01

Plain-language summary

Background: Why This Study Matters When someone suffers a severe injury (like from a car crash), they can bleed heavily. One complication doctors often face is something called Trauma-Induced Coagulopathy (TIC). This is a condition where the blood doesn't clot properly, making bleeding worse. The reasons behind TIC are complicated and not fully understood. One important substance involved is fibrinogen, a protein that helps blood clot. Low levels of fibrinogen are often the first sign of TIC and tend to be linked with how bad the injury is. Because of this, doctors have been giving trauma patients extra fibrinogen early on, hoping it will help them survive. However, a recent large study (called CRYOSTAT-2) showed that giving high doses of fibrinogen to all trauma patients didn't actually help reduce deaths. This suggests that not everyone needs it-only patients with very low fibrinogen levels (below 1.5 grams per liter) should get it. The problem is: it currently takes 30 to 45 minutes to get fibrinogen test results. In emergency situations, that's too slow. So doctors have been guessing who needs it, which might not always be the best approach. What This Study Aims to Do This new study wants to see if a faster, bedside test-called a point-of-care (POC) fibrinogen test-can be used in the Emergency Department (ED) during trauma resuscitations. Main Goals: Feasibility: Can the test be done quickly and easily during emergency care? Usefulness: If the fast test had been available, would doctors have made different decisions-like giving or not giving fibrinogen? And would that have changed outcomes for the patients? Study Details Feasibility Study: To see if the test is practical during trauma care. Retrospective Cohort Study: To look back at patients and see if early test results could have changed decisions or outcomes. Who's In the Study? Adults over 16 who arrive at the ED with serious trauma and for whom the hospital's Massive Transfusion Protocol was activated (meaning they had major bleeding). They must have received at least one unit of blood. How the Study Will Work The Test: A small amount of blood (0.15 ml) will be taken from blood that's already being drawn for routine care-so no extra blood draws are needed. The POC test (called qLabs Fib) will be done at the same time as standard lab tests. Important Note: Doctors won't make decisions based on this fast test for now. It's just being tested for feasibility. Nurses will note how long the test takes and if they had any trouble using it. Later, researchers will look back at the data to see: * What the fibrinogen levels were. * Whether the fast results could have helped guide better treatment. * If outcomes like how much blood was given or survival were affected. Why It Matters If the fast test works well, it could lead to * Faster, more accurate treatment in trauma cases. * Less unnecessary use of fibrinogen, saving resources and avoiding possible side effects. * Better outcomes for patients by tailoring treatment to their actual needs.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Population (base) Adult trauma patients will be identified as follows: (1) by the trauma team leader on admission to the ED or (2) by the research team personnel following a massive transfusion protocol activation. Patients will be assessed for eligibility to enter the trial according to the criteria set out below. If patients are eligible for entry into the study following initial screening, they will be enrolled automatically under deferred consent. Patients will be considered eligible for enrolment in this trial if they fulfil all the inclusion criteria and none of the exclusion criteria detailed below. Inclusion criteria To be eligible to participate in this study, a subject must meet the following criteria: * The participant is judged to be an adult (according to the attending clinician, e.g. 16 years or older) and has sustained traumatic injury * The participant is deemed by the attending clinician to have on-going active hemorrhage * The major hemorrhage protocol (MTP) is activated or this patient and transfusion is initiated Exclusion criteria * A potential subject who meets any of the following criteria will be excluded from participation in this study: * The participant has been transferred from another hospital * The trauma team leader deems the injuries incompatible with life

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
