Trigger Events list

Trigger events are the real-world processes that generate an exchange of messages. For example, admitting patients to the hospital is a trigger event that generates an Admit, Discharge, or Transfer (ADT) message.

These trigger events are associated with HL7 message types. Only specific message types and their associated trigger events are used by Clinical Science.

The trigger events are listed here. You can review them in the system by selecting Clinical Science > Setup > eHR Interface > Trigger Events.
