A company representative reported that unmatched orders can cause a potential mismatch of patient demographics.Patient a's records could be overwritten by patient b's records: when the user receives an order in through a host emr interface, merge lis has unmatched enabled for the emr orders interface.The order would go to unmatched if there was a demographic mismatch.The user would click on the order and click save as new patient and a window would appear, to enter the "medrec".The default value for this field is
.If the user leaves in the field instead of entering an mrn, and hits save, then if there is an mrn for another patient already in the database that matches the auto-generated mrn, the new patient's demographic data will overwrite the existing patient's data.
