  • Transfusions for anemia in adult and pediatric patients with malignancies. Blood reviews Shah, N., Andrews, J., Goodnough, L. T. 2015; 29 (5): 291-299


    Anemia is present in over two-thirds of patients with malignant hematological disorders. The etiology of anemia predominates from ineffective erythropoiesis from marrow infiltration, cytokine related suppression, erythropoietin suppression, and vitamin deficiency; ineffective erythropoiesis is further exacerbated by accelerated clearance due to antibody mediated hemolysis and thrombotic microangiopathy. As the anemia is chronic in nature, symptoms are generally well tolerated and often non-specific. Transfusion of red blood cells (RBCs) is a balance between providing benefit for patients while avoiding risks of transfusion. Conservative/restrictive RBC transfusion practices have shown equivalent patient outcomes compared to liberal transfusion practices, and meta-analysis has shown improved in-hospital mortality, reduced cardiac events, re-bleeding, and bacterial infections. The implications for a lower threshold for transfusion in patients with malignancies are therefore increasingly being scrutinized. Alternative management strategies for anemia with IV iron and erythropoietin stimulating agents (ESAs) should be considered in the appropriate settings.

  • Infusion Pump-Mediated Mechanical Hemolysis in Pediatric Patients ANNALS OF CLINICAL AND LABORATORY SCIENCE Hughes, J., McNaughton, J., Andrews, J., George, T., Bergero, C., Pyke-Grimm, K., Galel, S. A., Gonzalez, C., Goodnough, L. T., Fontaine, M. J. 2015; 45 (2): 140-147


    Hemoglobinuria was observed after packed red blood cell transfusion in a series of patients at our pediatric treatment center. Laboratory testing was suggestive of intravascular hemolysis with no support for an immunohematologic process.We investigated these adverse events to define a quality improvement plan and to prevent future hemolytic adverse events. Multiple factors were investigated, and the only change identified was the implementation of a new infusion pump (Pump A) that replaced a previous model (Pump B).In vitro pump analyses, a retrospective review of urinalyses, and prospective urinalysis and nursing surveillances were also performed.In in vitro analysis of the pumps, irradiated units with higher hematocrit at a low flow rate through Pump A had a greater than thirty-fold increase in free hemoglobin from baseline compared to minimal free hemoglobin changes seen with Pump B. Irradiated units with a lower hematocrit had a minimal change in free hemoglobin from baseline with both Pumps A and B at either low or high flow rate. Subsequently, only units with lower hematocrits were issued for transfusion of pediatric patients, and Pump A was replaced by Pump B in the outpatient unit. Retrospective and prospective surveillances found no additional unexplained cases of gross hemoglobinuria associated with transfusion.The investigation determined that infusion of higher hematocrit units using a specific commercial pump was associated with mechanical hemolysis. The change to units with lower hematocrit through an alternative pump has been an effective corrective action to date.

  • Evaluation of Febrile, Nonneutropenic Pediatric Oncology Patients with Central Venous Catheters Who Are Not Given Empiric Antibiotics JOURNAL OF PEDIATRICS Bartholomew, F., Aftandilian, C., Andrews, J., Gutierrez, K., Luna-Fineman, S., Jeng, M. 2015; 166 (1): 157-162


    To evaluate the practice of empiric antibiotics for febrile, nonneutropenic pediatric oncology patients with a central venous catheter (CVC) in place.Episodes of fever without neutropenia (absolute neutrophil count [ANC] ≥500 cells/mm(3)) were reviewed retrospectively in pediatric oncology patients with a CVC undergoing chemotherapy. Characteristics and symptoms were compared between patients with bacteremia and patients without bacteremia.A total of 392 episodes of nonneutropenic fever in 138 subjects (52 females; 38%) were reviewed. In this cohort, the median age at an episode was 7 years, and the majority of patients had a diagnosis of acute leukemia (54%). Median ANC was 3100 cells/mm(3) (IQR, 1570-5980 cells/mm(3)). Median temperature was 38.7°C (IQR, 38.3-39.2°C). Twenty-four infectious episodes (6%) occurred in 18 subjects, and 5 CVCs required removal; all patients requiring removal admitted and received antibiotics owing to chills. There were no significant difference in age, sex, or ANC between patients with bacteremia and those without bacteremia; however, mean temperature was higher in the patients with bacteremia (39.4°C vs 38.7°C; P = .003). No deaths due to sepsis occurred, and no CVCs were removed because antibiotics were not administered empirically.Our practice of observing pediatric oncology patients undergoing chemotherapy with CVCs who are not neutropenic does not appear to lead to increased serious adverse outcomes and avoids antibiotic exposure for >90% of patients without a bacterial infection.

  • Red Blood Cell Transfusion Is Not Associated with Necrotizing Enterocolitis: A Review of Consecutive Transfusions in a Tertiary Neonatal Intensive Care Unit JOURNAL OF PEDIATRICS Wallenstein, M.

  • Red blood cell transfusion is not associated with necrotizing enterocolitis: a review of consecutive transfusions in a tertiary neonatal intensive care unit. journal of pediatrics Wallenstein, M. B., Arain, Y. H., Birnie, K. L., Andrews, J., Palma, J. P., Benitz, W. E., Chock, V. Y. 2014; 165 (4): 678-682


    To explore the association between red blood cell transfusion and necrotizing enterocolitis (NEC) in a neonatal intensive care unit with liberal transfusion practices.A retrospective cohort study was conducted for all infants weighing <1500 g who received at least 1 packed red blood cell transfusion between January 2008 and June 2013 in a tertiary neonatal intensive care unit. The primary outcome was NEC, defined as Bell stage II or greater. The temporal association of NEC and transfusion was assessed using multivariate Poisson regression.The study sample included 414 very low birth weight infants who received 2889 consecutive red blood cell transfusions. Twenty-four infants (5.8%) developed NEC. Four cases of NEC occurred within 48 hours of a previous transfusion event. Using multivariate Poisson regression, we did not find evidence of a temporal association between NEC and transfusion (P = .32).There was no association between NEC and red blood cell transfusion. Our results differ from previous studies and suggest that the association between NEC and transfusion may be contextual.

  • Blood ordering from the operating room: turnaround time as a quality indicator TRANSFUSION McClain, C. M., Hughes, J., Andrews, J. C., Blackburn, J., Sephel, S., France, D., Viele, M., Goodnough, L. T., Young, P. P. 2013; 53 (1): 41-48


    Quality indicators in transfusion medicine are necessary for patient safety and customer satisfaction. The turnaround time (TAT) of issuing red blood cells (RBCs) has emerged as a quality indicator but is not an established benchmark. We examined the TAT for issuing RBCs from the blood bank to the operating rooms (ORs) at Vanderbilt University Medical Center (VUMC) and Stanford University Medical Center (SUMC).TAT was defined from time of request to when RBCs exited the blood bank. Cases eligible for analysis had completed type-and-screen results with requests for four or fewer RBC units. Patients with a positive antibody screen had serologically crossmatched units prepared and reserved for intraoperative use. We also e-mailed surveys to academic institutions to establish the current state of TAT monitoring and to anesthesiologists at VUMC to gauge the TAT expectations of the OR.The mean TATs at the two institutions were comparable (VUMC, 10 ± 3.8 min; SUMC, 14 ± 7.2 min) for orders of RBCs. The most common reasons for delayed TAT were overlapping orders, medical technologists occupied by phone calls, and oversaturation of pneumatic tube stations. Only 3 of 24 surveyed institutions actively monitored RBC TAT. Surveyed anesthesiologists (n = 7) reported an expectation for RBC TAT of 5 to 15 minutes for urgent cases. Established internal TAT policies were 15 and 20 minutes at VUMC and SUMC, respectively, for crossmatched RBC requests for patients with complete diagnostic testing.Many of the surveyed institutions do not monitor stat RBC issue TAT as a quality indicator. This study serves as a starting point for establishing a benchmark for TAT for issuing RBCs from the blood bank to ORs.
