Fayad Al-Haimus: Is Giving TXA Within ‘3 Hours’ Really Enough in Major Trauma?

Fayad Al-Haimus, Adult Thrombosis Fellow at McMaster University, shared a post on LinkedIn about a recent article by Adnan Ali  et al. published in Annals of Emergency Medicine:

“Important study to highlight:

Is giving TXA within ‘3 hours’ really enough?

A new Annals of Emergency Medicine analysis from the PATCH-Trauma trial challenges how we think about tranexamic acid (TXA) in major trauma.

Study context:
PATCH-Trauma enrolled >1,300 patients with major trauma across 15 EMS services and 21 trauma centres in Australia, New Zealand, and Germany. The new study was exploratory, post-hoc analysis of the trial.

Key finding:
TXA was associated with a significant reduction in 28-day mortality when given within ~90 minutes of injury.

<90 min: 17% vs 25% mortality (TXA vs placebo). Adjusted RR 0.64 (95% CI 0.50–0.82)
≥90 min: no mortality benefit (adjusted RR 1.04)

This is notable because:

• PATCH used precise prehospital timestamps, unlike CRASH-2
• TXA was given early, prehospital

Takeaway:
As trauma care becomes more precision-focused, this study adds to the growing signal that early hemostatic decisions matter as much as what we give.”
