IN this issue of Anesthesiology is a report on the next evolution of a patient blood management program.1  This report explores what was done at the Johns Hopkins Health System to take a successful program at their main hospital with a strong physician champion and disseminate the program to four other hospitals in their health system. To do so, they heavily leveraged the capabilities of their electronic health record, including a computerized physician order entry system and evidence-based decision support tools. These methods, which were complemented by widespread education, comprise the next steps in the evolution of patient blood management.
The domain of patient blood management started as bloodless medicine and surgery in the mid-1990s. In the bloodless model, a bloodless coordinator at each hospital was tasked with safeguarding the lives of patients who refused blood. From caring for bloodless patients, tools were developed that allowed major invasive procedures to occur without transfusion. Surprisingly, the outcomes for these patients were frequently better than for those who were transfused. The bloodless coordinators became advocates, sometimes to the point of zealotry, that “bloodless” was beneficial to all patients. Unfortunately, many physicians had issue with the term “bloodless” and its associated religious connotation. Thus, a move to relabel the field as “blood conservation” was undertaken. This label did not stick because there was significant fear of undertransfusion and withholding potential life-saving therapy. So another name change was made, with “blood management” being chosen.
The blood-banking community did not pay much attention because they felt that they practiced “blood management” every day as they managed their inventory of blood. So, a need to differentiate “inventory” blood management from what was done to benefit patients was required. A further change to the name was suggested, and “patient blood management” was born. Since this slight tweaking to the domain name, the area has rapidly blossomed and caught the attention of organizations such as the American Medical Association,2  the Joint Commission,3  and the World Health Organization.4 
As the name has evolved, so did the components that make up patient blood management. For some, it started with cell salvage and normovolemic hemodilution. It became a personal contest to avoid allogeneic transfusion in the bloodiest of procedures. Procedures such as open thoracic aneurysm repair, which routinely used 10 units or more of allogeneic blood, were being done with autologous blood only. At some point, we realized that to maximize the efficacy of blood salvage, preoperative anemia needed to be addressed. Sufficient erythrocytes could not be salvaged if patients were anemic before surgery. In conjunction with blood salvage, platelet and plasma utilization could be optimized with quantitative information that comes from point-of-care testing in the operating room or intensive care units.
As hospital mergers take place across the country, mechanisms to spread successful patient blood management programs to newly assimilated hospitals within health systems are needed. In this report, Frank et al.1  explore what was done to disseminate their patient blood management program across a five-hospital health system. To do so, they chose to move away from the model of having a bloodless coordinator at each hospital and to leverage information technology. They focused on two components of blood management: getting clinicians to abide by evidence-based guidelines and promoting single-unit erythrocyte transfusions rather than the classic two units. Focusing on these two areas, they created standardized order sets and best practice advisories. Through use of these tools, they recognized a 400% return on their fiscal investment to run the patient blood management program.
Building these tools requires extensive resources. In this report, the electronic health record Epic (USA) was used to create best practice alerts that notify a clinician in real time when they are deviating from the institutional recommendations. In conjunction with the alerts, they developed benchmarking reports comparing clinicians in each department as to their blood use and guideline compliance rates. For stand-alone or small hospitals with few resources, the ability to develop a patient blood management program as outlined by Frank et al.1  might be impossible. This may be one of the reasons that patient blood management programs have been slow to develop across the United States.
When writing a business plan to develop a blood management program, one needs to keep in mind that the opportunity for savings is related to the baseline amount of overuse. If your hospital is lost in an era of a hemoglobin transfusion trigger of 10 g/dl for erythrocytes and you always give blood by double-unit orders, then your savings could be great. If your facility is ordering one unit at a time, with frequent evaluation of the effectiveness of the transfusion, and carefully giving the blood when signs of inadequate oxygen delivery are occurring, then your opportunity might be small. Most experts in the field believe there is substantial blood- and cost-savings opportunity for the vast majority of hospitals where a patient blood management effort does not exist.
In addition to understanding one’s baseline practice, it is also important to assess how one will measure success. To illustrate, Goodnough et al.5  reported upon the success of a clinical decision support system implemented in 2010. If you look at their interval from 2011 to 2015, they had an increase in blood use of approximately 4%, but a 7% increase in patient volume, and a 20% increase in patient days at risk. This illustrates the need to volume adjust any changes in blood use. After volume adjustment (erythrocytes transfused/100 patient days), Goodnough saw a 14% reduction from 2011 to 2015 and an overall 42% reduction over a 7-yr period, indicating that their program was indeed a success.
Another aspect of this report highlights the role that an anesthesiologist can play in leading patient blood management. In general, hospitals purchase blood from blood providers. The only oversight of blood purchases and blood use has been through the “transfusion review committee.” In many hospitals, this committee is chaired by a blood bank physician. Given that blood is sold to the hospital by a blood center, which typically employs the blood bank physician, a natural conflict of interest occurs. Ideally the patient blood management team has representative clinicians from multiple disciplines, each with a unique perspective and contribution on how to promote best practices. However, many successful patient blood management programs with which I am familiar are run by anesthesiologists.
There are several other advantages to having an anesthesiologist oversee how blood is used. The anesthesiologist is the only provider that does not write an order for a transfusion. We transfuse it ourselves. With this clinical perspective, we have first-hand knowledge of logistical problems associated with transfusion, as well as associated waste related to the provision of blood not only in the operating rooms but also in the critical care units. Thus, anesthesiologists have insight into blood use that many other providers do not have.
Transfusion of allogeneic blood is the safest that it has ever been.6  Viral testing and electronic crossmatching have made complications associated with transfusion rare; however, complications still exist, such as the risk of circulatory overload, acute lung injury,7  or of new pathogens, like Zika,8  infecting the blood supply. Inherently, the safest transfusion is the one not given. Although the risks of transfusion can be debated, what cannot be argued is the cost. Acquisition cost of blood runs around $211 per unit of erythrocytes.9  Fully loaded costs of transfusion have been estimated to range from $500 to $1,200 per unit of erythrocytes.10  For my hospital system, the 330,000 units of blood comprise the largest line item on the laboratory budget, which naturally draws attention. As healthcare reform takes hold, the low-hanging fruit of the “triple aim,” i.e., providing safer care, improving the health of populations, and reducing per capita costs of health care, is easily achieved through patient blood management.
