Transfusion therapy in elective total hip arthroplasty

Area of Science:

• Orthopedic Surgery
• Transfusion Medicine
• Health Services Research

Background:

• Blood transfusions are common in orthopedic surgery, but overuse is a concern.
• Optimizing transfusion practices is crucial for patient safety and resource management.

Purpose of the Study:

• To audit blood transfusion practices in elective primary total hip arthroplasties.
• To identify unnecessary transfusions and assess the potential for reduction.

Main Methods:

• Retrospective audit of 150 consecutive total hip arthroplasty cases.
• Defined criteria for unnecessary transfusions: discharge hematocrit >36% or transfusion with <30% estimated blood volume loss.
• Correlated intra-operative blood loss with transfusion amounts.

Main Results:

• Overtransfusion occurred in 42-45% of patients based on defined criteria.
• Intra-operative blood transfused correlated significantly with intra-operative blood lost.
• Females lost less blood but received significantly more transfusions than males.

Conclusions:

• Significant overuse of blood transfusions was observed in elective primary total hip arthroplasties.
• Current transfusion practices may not align with established guidelines.
• Implementing quality assurance programs and monitoring transfusion practices is recommended to reduce overuse.
