3.2.11 ADT/ACK - cancel admit / visit notification (event A11)

For "non-admitted" patients, the A11 event is sent when an A04 (register a patient) event is canceled, either because of an erroneous entry of the A04 event, or because of a decision not to check the patient in for the visit after all. To cancel an A05 (pre-admit a patient) event, use the A38 (cancel pre-admit), which is new for Version 2.3 of this Standard.
