This section lists the use cases for using libraries of order sets.

1. A client of a content vendor’s system wishes to import the latest set of published order sets into its own catalog for deployment into its EHR.
1. A content vendor wishes to import a collection of order sets from one of its client including all dependencies (e.g., orderable items mentioned in the order sets, order details, relevant order item constraints, etc…) into its own catalog.
1. A health care provider wishes to sync its orderable item catalog and order set library with a content vendor. Any term added, updated, or inactivated should reflect immediately on the content vendor side. Also, the health care provider wishes to identify any catalog item that references an inactivated orderable item on the content vendor system in order to update the order set.
1. A medication has been recalled. A content provider and a health care provider would like to identify all order sets that reference this recalled medication. The health care provider then wishes to sync its order set library with that of the content vendor’s and update all affected order sets based on vendor guidance prior to reimporting the updated order sets back into their own catalog. The updated order sets, are then deployed into the EHR.
1. A health care organization with multiple facilities and hospitals maintains a master catalog of order sets. Each facility maintains its library of order sets and vocabulary derived from the master catalog but localized based on the facility’s needs and capabilities. Updates to the master catalog should be reflected at the individual facility/hospital level based on the governance practices of the facility and the parent organization.
1. The client of a content vendor would like to import order sets ready for publication into their system. They search the catalog for all active order sets that are ready for publication and import that set into their local catalog. Once imported, an integrator reviews the order sets, makes the necessary changes, and deploys them to the EHR.
