3.2.29 ADT/ACK - delete person information (event A29)

An A29 event can be used to delete all demographic information related to a given person. This event "undoes" an A28 (add person information) event. The information from the A28 event is deleted. This event is used, for example: when adding the information was performed in error, or when another record already exists for the person, or one wants to purge the person from the database. When this event occurs, all visit and account level data for this person is also purged.

The fields, included when this message is sent, should be the fields pertinent to communicate this event. When other important fields change it is recommended that the A08 (update patient information) event be used instead.
