This is the home page for the award winning Orders & Observations Work Group.

2018 Work Group Health All-Star Award


The mission of the Orders and Observation work group is to define information exchange capabilities to support the order/scheduling and clinical event management/reporting requirements between the stakeholders in the healthcare organization regarding patients, non-patients, people, other species, or inanimate objects. These information exchanges are not limited to intra-organizational transactions, but may cross organizational boundaries. These information exchanges may involve messages, documents, services, and other HL7 constructs.
