Summary
Unnecessary blood preparation for total knee arthroplasty (TKA) was significantly reduced. This initiative improved effective transfusion rates and lowered medical costs, enhancing patient safety and resource management.
Area of Science:
- Orthopedic Surgery
- Transfusion Medicine
- Healthcare Management
Context:
- High rates of allogenic blood preparation (100%) for elective total knee arthroplasty (TKA) at the institute.
- Significant waste of prepared blood (76.2%) due to unnecessary preparations.
Purpose:
- To decrease unwarranted blood preparations for elective TKA.
- To reduce associated resource expenditures and waste.
Summary:
- Addressed issues of transfusion uncertainty, inadequate high-risk patient evaluation, and outdated clinical pathways.
- Redefined transfusion triggers with empirical data, fostered medical team consensus, and updated clinical protocols.
- Implemented a comprehensive risk assessment and revised blood preparation/transfusion procedures.
Impact:
- Reduced blood preparation rates from 100% to 10.2%.
- Increased effective transfusion rates from 23.8% to 76.2%.
- Demonstrated a model for improving patient safety and lowering medical costs through interdisciplinary collaboration.

Accurate blood pressure assessment is crucial for diagnosing and managing various health conditions. To ensure the reliability of these measurements, healthcare professionals must adhere to standardized pre-procedural guidelines. These guidelines enhance patient safety and improve the overall quality of healthcare. The following steps are essential for obtaining accurate and consistent blood pressure readings, from using the appropriate tools to ensuring effective communication with the patient.
