ADT_A16
ADT^A16 Acknowledgment Choreography
ADT^A16
An A16 event notifies other systems of a plan to discharge a patient when the patient has not yet left the healthcare facility. It is used when advanced notification of a discharge is required in order to prepare for the patient's change in location. For example, it is used to notify the pharmacy of the possible need for discharge drugs or to notify psychotherapy of the possible need for post-discharge appointments or to notify the extended care or home health system that the patient will be discharged and that the new extended care and home health admission assessment can be scheduled.
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 in addition.
