The transfusion rate across CABG sites ranged from 7.8% to 92.8% for red blood cells (RBCs) and from 0% to 97.5% for fresh-frozen plasma. Although geographic location, academic status, and hospital volume were all significant factors, these three characteristics accounted for only a small (11.1%) portion of the variation in risk-adjusted RBC usage. The investigators write that\u00a0&#8220;to our knowledge, there has never been a large randomized trial of the safety and efficacy of blood transfusion in cardiac surgery; therefore, some of the variability we observed may be due to honest differences between clinicians in the perceived benefits and risks of transfusion.&#8221;<\/p>\n<p>In an attempt to shed some light on the topic, <a href=\"http:\/\/jama.ama-assn.org\/cgi\/content\/short\/304\/14\/1559\">Hajjar and colleagues<\/a> performed the propspective Transfusion Requirements After Cardiac Surgery (TRACS) clinical trial. They randomized 502 patients at a single university hospital in Brazil to either a liberal strategy of blood transfusion or a restrictive strategy (hematocrit goal of <span style=\"text-decoration: underline;\">&gt;<\/span> 30% or <span style=\"text-decoration: underline;\">&gt;<\/span>24%). Some 78% of patients in the liberal strategy group received a transfusion, compared with 47% in the restrictive-strategy group. The composite endpoint of 30-day mortality, cardiogenic shock, acute respiratory distress syndrome, or acute injury requiring dialysis or hemofiltration did not differ significantly between the two groups (10% vs. 11%, P=0.85).<\/p>\n<p>In <a href=\"http:\/\/jama.ama-assn.org\/cgi\/content\/short\/304\/14\/1610\">an accompanying editorial<\/a>, Aryeh Shander and Lawrence Goodnough observe that Society of Thoracic Surgeons ratings of cardiac surgery programs do not include RBC transfusions as a quality indicator and suggest that &#8220;it may be time for patient blood management to gain status as a performance indicator by accreditation agencies such as the Joint Commission or as a quality indicator by professional organizations.&#8221; They conclude:<\/p>\n<p style=\"padding-left: 30px;\">&#8220;When evaluating a hemoglobin level, treating physicians must resist the temptation to &#8216;first do something&#8217; and temper this temptation with a philosophy of &#8216;first do no harm&#8217; to achieve the optimal balance of providing the best risk-benefit and cost-effective outcomes of transfusion therapy for patients.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>One new study in JAMA demonstrates very wide differences among hospitals in the use of transfusions during cardiac surgery.
