Summary
Red blood cell (RBC) transfusion practices in hip arthroplasty vary widely in Denmark, with significant differences between hospitals. Further research is needed to determine the optimal transfusion strategy and its impact on patient outcomes.
Area of Science:
- Orthopedic Surgery
- Transfusion Medicine
- Health Services Research
Background:
- Optimal red blood cell (RBC) transfusion strategies for hip arthroplasty are not well-defined.
- Existing guidelines have not standardized transfusion practices in Denmark.
- Significant inter-hospital variation in transfusion rates exists.
Purpose of the Study:
- To evaluate current RBC transfusion practices in primary total hip arthroplasty (THA) and revision total hip arthroplasty (RTHA) in Denmark.
- To assess the variation in transfusion rates and timing across different Danish centers.
- To identify potential associations between transfusion and patient outcomes.
Main Methods:
- Retrospective cohort study of THA and RTHA patients in Denmark during 2008.
- Analysis of inter-center variation in RBC transfusion rates.
- Examination of transfusion timing relative to surgical procedures.
Main Results:
- 24% of THA and 61% of RTHA patients received RBC transfusions.
- 47% of THA and 73% of RTHA transfusions occurred on the day of surgery.
- Transfusion rates varied dramatically between centers (7-71% for THA, 26-85% for RTHA).
- RBC transfusion was associated with longer hospital stays and increased 90-day mortality risk in THA patients.
Conclusions:
- RBC transfusion practices in Danish hip arthroplasty are highly variable, despite guidelines.
- The impact of RBC transfusion on hip arthroplasty outcomes requires further investigation.
- Prospective randomized controlled trials are recommended to establish optimal transfusion protocols.

Blood transfusion is a therapeutic measure to restore the blood volume after extensive blood loss due to an accident or a medical procedure. Blood transfusion involves drawing a certain amount of blood from a suitable donor and infusing it into the recipient.
History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...
