A standardized massive hemorrhage protocol (MHP) was developed using expert consensus to improve patient care during life-threatening bleeding. Harmonizing MHPs enhances training, communication, and patient outcomes.
Area of Science:
- Medical Science
- Trauma Care
- Transfusion Medicine
Background:
- Massive hemorrhage protocols (MHPs) facilitate rapid blood component delivery for exsanguinating patients.
- Variability in MHP implementation, content, and compliance presents challenges.
- Developing a standardized regional MHP is crucial for consistent care.
Purpose of the Study:
- Identify key evidence-based principles for a standardized regional MHP.
- Establish quality indicators for MHP implementation.
Main Methods:
- Modified Delphi consensus technique with 36 experts.
- Independent rating of 43 statements and 8 quality indicators on a 7-point Likert scale.
- Inclusion of external stakeholder input from Ontario hospitals.
Main Results:
- Consensus reached on 42 statements and 8 quality indicators.
- Modifications incorporated from external stakeholders.
- Foundation established for a proposed MHP.
Conclusions:
- A template for a harmonized MHP toolkit was created.
- Recommendations for pediatric, obstetrical, and resource-limited settings included.
- Harmonization aims to simplify training, increase uptake, improve communication, and enhance patient safety and outcomes.
