Background:
The return of joint drainage after hip and knee arthroplasty is a widely used but expensive blood-conservation technique.
Study Design And Methods:
A Markov decision analysis model was used to evaluate the cost-effectiveness of postoperative RBC recovery in preventing viral complications of allogeneic transfusion.
Results:
In the baseline analysis, using an RBC-recovery device saves 5 quality-adjusted minutes of longevity at an average incremental cost of $53. This corresponds to $5.7 million per quality-adjusted life year. This figure was most sensitive to the direct cost differences of allogeneic versus recovered RBCs and to the volume of RBCs recovered per device. Such devices would save health care resources if they cost less than $73 or if they were applied only in cases where joint drainage was between 600 and 1100 mL.
Conclusion:
For most clinical situations, postarthroplasty RBC recovery does not appear to be as cost-effective as most other medical interventions. Clinical attention should be directed toward developing protocols for the preferential use of postoperative RBC-recovery devices in situations where they provide the greatest benefit.

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...
