Study summary

The current process for getting complete blood cell counts (CBC) results in the operating room during surgery relies on sending blood samples from the operating room to the hospital's central lab. This workflow is complex and often results in handing off the blood sample to 4 or more different staff members before arriving in the lab for analysis. This often causes delayed CBC results, which may lead to inappropriate or delayed clinical decision making. By providing prompt access to CBC results with the use of a point of care CBC analyzer, the clinical workflow efficiency can be significantly improved. This should resulting in better clinical decision making, reductions in costs, increase in patient satisfaction and facilitation of hospital processes.
