Trends in red blood cell transfusion and 30-day mortality among hospitalized patients
Background Blood conservation strategies have been shown to be effective in decreasing red blood cell (RBC) utilization in specific patient groups. However, few data exist describing the extent of RBC transfusion reduction or their impact on transfusion practice and mortality in a diverse inpatient population

A multicentre study investigating vital sign changes occurring in complicated and uncomplicated transfusions
BACKGROUND AND OBJECTIVES:Many hospitals require transfusions to be discontinued when vital signs stray from predetermined ranges, regardless of clinical symptoms. Variations in vital signs may be unrelated to transfusion, however, and needlessly stopping a transfusion may delay medical care while increasing donor exposures and healthcare costs. We hypothesized that a detailed study of vital sign changes associated with transfusion of blood product by component, including those associated with potential reactions (complicated) and those deemed to be uncomplicated, would establish a useful framework of reference for treating clinicians and transfusion services alike. MATERIALS AND METHODS:A retrospective electronic record review of transfusion service and transfusion recipient data was completed on 3852 inpatient transfusion episodes over a 6-month period at four academic tertiary care hospitals across the United States. Vital signs pre- and post-transfusion were recorded by trained clinical research nurses. Serious reactions were adjudicated by a panel of transfusion medicine experts. RESULTS:In both uncomplicated transfusions (n = 3765) and those including an adverse reaction (n = 87), vital sign fluctuations were generally modest. Compared to uncomplicated transfusions, transfusions complicated by febrile reactions were associated with higher pretransfusion temperature and higher pretransfusion pulse rates. Episodes of transfusion circulatory overload were associated with higher pretransfusion respiration rates compared to uncomplicated transfusions. CONCLUSION:Most transfusions are associated with only modest changes in vital signs. Pretransfusion vital signs may be an important yet previously understudied predictor of vital sign changes during transfusion. The optimal role of vital sign assessment during blood transfusion deserves further study
Therapeutic impact of red blood cell transfusion on anemic outpatients: the RETRO study
BACKGROUND:Patients with cancer or other diagnoses associated with chronic anemia often receive red blood cell (RBC) transfusion as outpatients, but the effect of transfusion on functional status is not well demonstrated. STUDY DESIGN AND METHODS:To estimate the effect of transfusion on functional status and quality of life, we measured 6-minute walk test distance and fatigue- and dyspnea-related quality-of-life scores before and 1âweek after RBC transfusion in 208 outpatients ageââ„50 with at least one benign or malignant hematology/oncology diagnosis. To account for potential confounding effects of cancer treatment, patients were classified into two groups based on cancer treatment within 4âweeks of the study transfusion. Minimum clinically important improvements over baseline were 20 meters in walk test distance, 3 points in fatigue score, and 2 points in dyspnea score. RESULTS:The median improvement in unadjusted walk test distance was 20 meters overall and 30 meters in patients not receiving recent cancer treatment. Fatigue scores improved overall by a median of 3 points and by 4 points in patients without cancer treatment. There was no clinically important change in dyspnea scores. In multiple linear regression analysis, patients who maintained hemoglobin (Hb) levels of 8âg/dL or greater at 1âweek posttransfusion, who had not received recent cancer treatment, and who did not require hospitalization during the study showed clinically important increases in mean walk test distance. CONCLUSIONS:Red blood cell transfusion is associated with a modest, but clinically important improvement in walk test distance and fatigue score outcomes in adult hematology/oncology outpatients
