The transfusion of red blood cells was the most widely used, and anesthesiologists were responsible for approximately 50% of transfusions. In recent years, however, the use of transfusions has decreased in surgical areas, and currently the 2 departments that employ most employ transfusions are the oncohematology and emergency departments.<a class="elsevierStyleCrossRef" href="#bib0020"><span class="elsevierStyleSup">4</span></a></p><p id="par0150" class="elsevierStylePara elsevierViewall">Although PRBC transfusions have been employed for many years and can save many patients with acute or chronic anemia, the results of this study conducted in emergency departments show that there is a high rate of unnecessary transfusions in both diseases. In HoS, which has a commitment to train practitioners on the appropriateness of PRBC transfusion,<a class="elsevierStyleCrossRefs" href="#bib0040"><span class="elsevierStyleSup">8–10</span></a> we observed that the management of blood products had greater appropriateness. A recent survey by the American Association of Blood Banks showed that only 38% of public hospitals had an established program for managing blood products and patient transfusions. This program should be extended to all hospitals because it has been shown that local transfusion programs and committees promote patient safety, improve the quality of medical care and reduce unnecessary expenses.</p><p id="par0155" class="elsevierStylePara elsevierViewall">Anemia is characterized by an insufficient quantity of healthy red blood cells, which are responsible for oxygenating the tissues and organs of the body and whose deficiency can therefore cause severe damage in these vital organs. In general, anemia is considered hemoglobin values <12<span class="elsevierStyleHsp" style=""></span>g/dL and <14<span class="elsevierStyleHsp" style=""></span>g/dL and hematocrit levels <36% and <41% for women and men, respectively. This disease is often underdiagnosed and undertreated and has a very high rate of comorbidity. Detection and appropriate treatment help reduce the need for transfusions, given that transfusions, although effective against anemia, are associated with numerous risks and complications. It is therefore essential to implement patient blood management programs, as urged by the World Health Organization in the 63rd Assembly of June 2010 and promoted the same year by the Council of Europe in the so-called “optimal use of blood”.<a class="elsevierStyleCrossRef" href="#bib0055"><span class="elsevierStyleSup">11</span></a></p><p id="par0160" class="elsevierStylePara elsevierViewall">Depending on the mechanism of red blood cell destruction, the treatment for anemia should focus on its origin and not prioritize increasing hemoglobin levels. Blood transfusion is currently one of the most widely used treatments in Spanish emergency departments to treat anemia. Although this disease is generally accompanied by a reduction in erythrocyte mass, a reduction in the number of red blood cells does not have to occur. Therefore, a PRBC transfusion is perhaps not the best treatment option in these cases. Our study showed that only 54.86% of the PRBC transfusions were performed appropriately following the clinical guidelines criteria based on the patients’ hemoglobin levels and previous diseases; however, there was a considerable difference between the two diagnoses, with 69.71% of the cases of chronic anemia having appropriate PRBC transfusions versus 36.99% in the case of acute anemia.</p><p id="par0165" class="elsevierStylePara elsevierViewall">For this reason and because PRBC transfusions are an expensive and scarce resource associated with known complications and adverse effects to be considered when prescribing them to patients, other better alternatives for the treatment of anemia should be considered, based on the disease’s etiology, symptom severity and associated comorbidity. In these cases, a detailed medical history and anamnesis are essential when administering the best treatment for the patient. Logically, treating anemia will depend on its cause and severity. On many occasions, however, the prescription of iron, vitamin B12 and folic acid supplements, erythropoietin and medications that inhibit the immune system can be good alternatives to blood component transfusion. In fact, in countries such as the US and the UK, treatment based on PRBC transfusion fell 30–50% within a few years,<a class="elsevierStyleCrossRefs" href="#bib0060"><span class="elsevierStyleSup">12,13</span></a> with a priority on therapeutic alternatives.

Within their delegated powers, the autonomous communities of Spain have established that all centers with transfusion practices require a transfusion committee for the correct use of blood and blood components. The committee’s functions, as a minimum, are the following: a) Determine the standards and procedures for the transfusion practice adapted to the clinical activities performed in each hospital center; b) Periodically analyze and evaluate the transfusion practice; c) Analyze and assess the adverse reactions associated with transfusions; d) Develop educational programs that promote the optimal use of blood components; e) Develop and implement preventive and/or corrective safety measures; and f) Any other functions they consider would help promote the optimal use of blood, components and derivatives and in reducing their consumption.</p><p id="par0175" class="elsevierStylePara elsevierViewall">Other options studied in the context of the politics of managing patients’ blood include multifactorial strategies. Langlais et al.<a class="elsevierStyleCrossRef" href="#bib0075"><span class="elsevierStyleSup">15</span></a> adopted a series of strategies aimed at improving the transfusion practices in surgery departments through seminars, classes, periodic consultations and the creation of information points.
