BACKGROUND: Data on red blood cell (RBC) transfusion in the United States show variation in practice and overprescribing or overdosing is considered to be prevalent. Education or restrictive interventions could modify practice.
STUDY DESIGN AND METHODS: RBC transfusion and mortality rates were recorded in a single institution over a 15-year period. The first 3 years were used as a baseline. Education measures were used to influence practice for 3 years followed by a 9-year period when questionable RBC orders in nonbleeding inpatients resulted in prospective physician notification for potential modification. Physician notification was done by blood bank technologists with transfusion medicine physician support, if needed. Pretransfusion hemoglobin levels of more than 9 g/dL were recommended for cancellation and levels between 8 and 9 g/dL advised for a single unit, if 2 or more units were requested. RBC transfusion rates were described as inpatient units per 1000 discharges to allow for interyear comparison.
RESULTS: A downward trend in RBC transfusion was noted for the intervention period. Comparison of the baseline period with the past 3 years of the intervention period showed an approximate 33% decrease, which was highly significant (508 ± 66 vs. 341 ± 32, p < 0.01). Inpatient mortality rates declined over this period.
CONCLUSION: Physician education in appropriate transfusion practice is desirable but may not greatly impact RBC use. Engagement of physicians who prescribe RBCs that appear inappropriate for indication or dose was associated with a significant decline in RBC use without evidence of a change in mortality.
