Red cell transfusion in orthopaedic surgery: a benchmark study performed combining data from different data sources.

Area of Science:

• Medical Informatics
• Healthcare Management
• Transfusion Medicine

Background:

• Assessing blood transfusion appropriateness requires understanding the conditions leading to blood use.
• Previous research highlights the value of integrating diverse data sources to analyze transfusion practice variations.

Purpose of the Study:

• To combine blood transfusion data with patient information to analyze transfusion practices in orthopaedic surgery.
• To identify factors influencing red blood cell transfusion rates and variations between clinical divisions.

Main Methods:

• Data from Blood Bank and Hospital Discharge databases (ICD9) were integrated for 1,827 orthopaedic procedures (hip/knee replacements, femoral fracture operations).
• Patient demographics, surgical procedure type, and transfusion outcomes were analyzed.
• For a subset, data were further combined with laboratory hemoglobin values.

Main Results:

• Over half (56.8%) of the procedures resulted in red blood cell transfusion.
• Transfusion likelihood varied by patient sex, age, and surgical procedure, with higher rates for post-femoral fracture operations and hip revision surgeries (approx. 70%).
• Significant variability in transfusion rates was observed across seven divisions, even for similar procedures, indicating factors beyond surgical type.

Conclusions:

• Integrating data from disparate sources offers an efficient method for gaining insights into transfusion practices.
• This integrated approach can contribute to the optimization of blood resource utilization in healthcare settings.
