Way more than you'd think Scott. There's plenty of resistance to change in our industry. I inspected a transfusion service where the entire hospital was on EMR, the laboratory had an LIS, but the blood bank supervisor had won their case to keep blood bank computer-less. They also did all IAT crossmatches. Interestingly enough, most of the techs weren't even aware that you could opt for IS crossmatches, leading me to believe that most other hospitals in that region were doing something similar.
