3.2.28 Add person information (event code A28)
3 segments
The purpose of this message and the three following messages is to allow sites with multiple systems and respective master data bases to communicate activity related to a person between systems. Each system has an interest in the data base activity of the others in order to maintain data integrity across an institution. While defined within the ADT message set, these messages differ in that they are not patient specific.
For example, a site with separate inpatient, outpatient and medical record systems may require that each system maintain concurrent person information. Prior to an admit, in the inpatient system the new patient is added to the master data base of the system resulting in the broadcast of a message. The outpatient system receives the message and adds the person to its data base with the possibility that the person may some day become a patient in its system. The medical record system receives the message and adds the person to its data base with the possibility that it will track inpatient, outpatient or clinical data for the person.
