Recently my department had this same discussion. We perform the IAT on all preadmission samples and is recorded on the patients order request. The day before the secheduled OR a Type is performed and the IAT results are recorded. The IAT results are footnoted with a comment (Tech/DATE results when performed). Our computer system does not let us cross over the drawn date sample to the admit date. It does not drop the correct billing account. Supposedly the system is not able to merge the account numbers. I think there may be some compliance issues with our process. According to AABB guidelines : read , record , result when testing... entering results thats was not performed by the tech introduces error. We have Cerner Millenieunm and it has been an ongoing problem. I am not comfortable entering results that I have not done. Just another source of error. I would like to change this process to avoid data entry problems . Any suggestions!
