We use a separate BB wristband, perform electronic crossmatch, and require a second draw on patients for whom we have no type history. (We may also use a separate draw, ie. CBC if available). Last year, a patient was registered incorrectly (same name, different date of birth - so all bands, charts and labels were incorrect). It was caught by the phlebotomist performing that second draw. If I had ever questioned our process, I certainly did not look back after that near miss. We have to remember that patient identification IS the number one safety goal, because everything stems from that.
