Abstract
Primary total hip arthroplasty (THA) is among the most common surgical procedures and clinically known to cause significant intraoperative blood loss requiring peri- and post-operative transfusion. Multiple studies have shown post-operative transfusions are associated with greater complications and subsequent prolonged recovery, however limited studies exist in determining whether similar post-operative risks are observed in THA patients receiving pre-operative transfusions. Based on studies conducted on post-operative transfusions, it was hypothesized that pre-operative transfusions would be associated with an increased risk for post-operative complications.
In total, 74,814 patients from the National Surgical Quality Improvement Project Database between 2005-2014 were studied with specific readmission/reoperation data beginning in 2011. Complications were divided post-operative complications (directly related to the procedure), and non-operative complications (not associated with procedure), and co-morbidities were controlled during multi-variate analysis.
Pre-operative transfusion in THA patients was found to be an independent predictor of organ space infection (OR: 5.41), pneumonia (OR: 2.66), failure to wean (OR: 13.84), urinary tract infection (OR: 3.42), cardiac arrest (OR: 5.83), transfusion post-operatively (OR: 5.94), and non-home discharge (OR: 3.18).
Overall, patients receiving blood products prior to a primary THA are at increased risk of operative and non-operative complications including increased infection risk, prolonged hospital stay, discharge to a non-home facility, and potential cardiac arrest leading to resuscitation. Future medical decision making regarding pre-operative anemia management in primary THA cases should entail a careful risk-benefit analysis of transfusion and potentially include higher thresholds to transfuse preoperatively as well as, close monitoring in order to prevent complications.
