Massive bleeding or hemorrhage is one of the most serious intraoperative complications, occurring in up to 68% of uncontrolled bleeding events and about 3% of surgeries. It is a leading cause of death in operating rooms worldwide. Recognizing that efficient coordination is vital in high-stakes surgical emergencies, the Perioperative Services team at Kaiser Permanente Sacramento Medical Center implemented an interdisciplinary Mock Massive Transfusion Protocol Drill led by Amelia Dayucos, MSN, RN, CNOR, Nursing Professional Development Specialist for Perioperative Services.

The simulation brought together nurses, anesthesia providers, surgical technologists, the blood bank, and pharmacy teams to rehearse rapid-response procedures for a critical bleeding event. Guided by Dayucos’ leadership, the exercise emphasized clear communication, defined roles, and seamless teamwork, which are key elements that ensure safety and improve outcomes during real MTP activations.

“Our goal was to ensure that every team member understands their role and can act decisively in a coordinated way,” said Dayucos. “In massive transfusion events, precision and teamwork are essential to patient safety.”

Interdisciplinary drills such as this improve technical readiness and foster enhanced team dynamics, communication, and trust. Through interprofessional education, participants develop the ability to anticipate colleagues’ needs and respond collaboratively to emergencies. Post-drill feedback indicated increased confidence and role awareness among all participants.

“These simulations demonstrate our commitment to high reliability and quality care,” said Mary Jane Talento, MSN, RN, CNOR. “They reinforce our ability to deliver safe, coordinated care when it matters most.”

Building on the success of this initiative, Perioperative Services now incorporates regular interdisciplinary simulations into ongoing staff education and readiness training.
