Improved efficiency in providing blood to surgical patients using a novel approach to preadmission testing

Expansion of the preadmission process for same-day-admit (SDA) surgery patients through our Admissions Evaluation Center has provided an efficient and convenient means for complete patient evaluation up to 30 days in advance of surgery. Traditionally, collection of blood samples for the pretransfusion testing that is necessary to select compatible blood for transfusion occurs within 72 hours of admission, consistent with standards to ensure detection of red blood cell (RBC) alloantibodies formed as a result of recent transfusion or pregnancy. As a result, samples for many SDA patients were submitted Stat the morning of surgery, resulting in an unwieldy amount of testing and delay in blood availability. To address this problem, the time interval for collection of patient blood samples for pretransfusion testing was extended to 30 days prior to surgery. To ensure safety, this change required documentation of patient transfusion and pregnancy history at 2 specific timepoints. Input from a multidisciplinary team was vital to assess the process of blood ordering and administration and to determine the best means to accomplish these steps. Implementation of the new process resulted in a decreased number of emergent requests for compatibility testing, decreased delays in blood delivery, and elimination of canceled surgery due to cases with unexpected RBC antibodies.
