RESUMO
Currently there are no widely accepted guidelines regarding the appropriate use of O- red blood cells (RBCs). Although there has been a decline in overall RBC utilization since 2010, the use of O- RBCs has continued to proportionally increase over this time period resulting in frequent shortages. When faced with these shortages, we implemented some simple strategies that resulted in a significant decrease in annual O- RBC utilization from 10% to 7.5% despite an increase in total RBC utilization. These strategies included collaboration with the clinical staff, improving practices within the blood bank, and having our health system partner with our blood supplier. Herein, we detail our strategies for hospital transfusion services to improve O- RBC utilization. Most of these can be easily implemented and do not require additional resources.

We analyzed our historic patient database at North Shore University Hospital and determined both the overall frequency of anti-Js(a) and the frequency at which it was detected in combination with other alloantibodies to red blood cell (RBC) antigens. Screening cells used currently are negative for Js(a). Our data suggest that anti-Js(a) would not be detected in 30 to 40 percent of patients in which it is the sole antibody present. Since 1996 the antibody was only detected when other antibodies were found in the screening process. We are exposing 1.7 percent of our patients (90 patients/year) to Js(a). The clinical significance of anti-Js(a) is apparent with previous literature, and our conclusion is that additional studies should be performed to determine whether Js(a) should be included in current antibody screening cells.
