A retrospective study to evaluate the time burden associated with outpatient red blood transfusions indicated for anemia due to concomitantly administered chemotherapy in cancer patients

Abstract

Purpose: Anemia in cancer patients can be treated with red blood cell (RBC) transfusions. The patient burden associated with a treatment in terms of total time spent is an important factor to consider when measuring the benefits and challenges of a therapy. This study estimates the time-related patient burden associated with outpatient RBC transfusion.

Methods: A retrospective chart review of outpatient cancer patients receiving a RBC transfusion was conducted at 10 US centers. RBC transfusion time was measured as time elapsed from pre- to post-transfusion vital sign assessment and from transfusion start to stop time. Elapsed time from hemoglobin level testing and blood draw for cross-match to transfusion, estimated travel time and distance, and clinical and demographic data were also collected.

Results: Data from 110 patients (48.2 % male; mean age 64 ± 12 years) showed that the mean elapsed time between pre- and post-vital sign assessment was 4.2 h (95 % confidence interval (CI), 3.64-4.81) including 3.6 h (95 % CI, 3.0-4.1) on average to receive the actual RBC transfusion treatment. Hemoglobin level testing (mean Hg level, 8.33 g/dL ± 0.67) and blood drawn for cross-match were completed in an average of 31.2 h (95 % CI, 17.0-45.5) and 18.2 h (95 % CI, 12.1-24.2) prior to transfusion, respectively. Patient one-way travel time averaged 30.0 min (95 % CI, 25.9-34.3).

Conclusions: In the US, CIA patients experience an important time burden when being treated with RBC transfusion in addition to the burden already added by chemotherapy.
