In the Outpatient Update Transaction, the EHR-S provides updated patient demographics to the DSS/OF.  The DSS/OF can apply those demographics to Requested Procedures based on orders previously received from the EHR-S, and forwards the update to the Image Manager. This transaction is identical to Patient Update [RAD-12] (see RAD-TF 2: 4.12), with the ADT actor replaced by the EHR-S, and limited to a subset of the trigger events specified in RAD-12.
