Massive hemorrhage protocol survey: Marked variability and absent in one-third of hospitals in Ontario, Canada

BACKGROUND: Massive hemorrhage protocols (MHP) are critical to standardized delivery of timely, safe, and resource-effective coordinated care for patients with life-threatening bleeding. METHODS: A standardized MHP survey was sent to all hospitals (n = 150) in Ontario with a transfusion service. This study aim was to determine the proportion of hospitals with an MHP and assess for variability.
