Evaluation of Erythropoietin Stimulating Agents (ESA) and Their Effect on Blood Optimization for Cardiac Surgery.

BACKGROUND: Cardiovascular surgeries increase the risk of receiving blood transfusions. Erythropoietin stimulating agents (ESAs) have been used to decrease the transfusion rate. The objective of this study was to evaluate the administration of blood products post-cardiothoracic surgery after receiving ESAs. METHODS: This is a single-center, retrospective cohort study. RESULTS: Between May 2017 to May 2018, 52 adult patients underwent cardiac surgery and received ESAs pre-operatively and/or post-operatively. A total of 35 patients were included in the study and 21 (60%) patients did not require a blood transfusion while 14 (40%) patients required a blood transfusion (p = 0.597). The change in hemoglobin (Hgb = 0.773 g/dL, 1.7 g/dL; p = 0.002) and hematocrit (Hct = 2.31%, 4.3%; p = 0.04) was significantly different in patients who received ESAs alone versus ESAs with blood transfusion. Adverse drug reactions showed no significant difference between groups. CONCLUSIONS: In patients undergoing cardiac surgery, ESAs did not significantly reduce the need for blood transfusion. Future and larger studies are necessary to evaluate the effect of ESAs on blood transfusion.

The complexity of cancer chemotherapy requires pharmacists be familiar with the complicated regimens and highly toxic agents used. This column reviews various issues related to preparation, dispensing, and administration of antineoplastic therapy, and the agents, both commercially available and investigational, used to treat malignant diseases.
