An article by B. Dixon et al. in the January issue of "Transfusion" examines whether blood transfusion during cardiac surgery is a cause of patient mortality. The authors found that blood transfusion was not an independent predictor of mortality, whereas chest drainage was the strongest independent predictor. The investigators further noted that the effect of chest tube drainage on mortality was present even for patients not receiving a transfusion. A video on this research has been posted on TransfusionNews.com and continuing medical education credits are being offered for reading and successfully completing a test on the article.
