TOFU is a two-arm, cluster-randomized controlled trial. Initially, baseline blood use data will be collected at all study sites. Next, the PI at each site will give a short educational presentation to the orthopedic surgeons. The presentation will consist of a standardized 10-minute presentation reviewing the data from the FOCUS trial and the recommended red blood cell (RBC) transfusion trigger of 8 g/dL (or symptomatic anemia) based on that data. Clusters of orthopedic surgeons will then be randomized to either the Control arm (no feedback) or the Intervention arm (monthly feedback). All of the surgeons at a given site will either receive or not receive feedback. The feedback will take the form of emailed monthly reports detailing blood use by each surgeon post-hip surgery. Surgeons will be anonymized in the reports as "A, B, C . . ." but each surgeon will know which data are his own. The primary end point is the decrease from baseline in the proportion of patients transfused with a pretransfusion hemoglobin of > 8 g/dL.
