This study from the Michigan Society of Thoracic and Cardiovascular Surgeons Quality Collaborative evaluated outcomes of CABG in 33 hospitals 2011-2013, assessing the association of blood transfusion (39.9% of pts) and the incidence of postoperative pneumonia (3.6% of pts). Blood transfusion was associated with an increased risk of pneumonia (OR 3.4), and there was a dose-response relationship between the number of units transfused and pneumonia risk.
