3. NEW SWF Options • Departmental Appointment Notification • Gives the Department System Scheduler an option to notify Order Placer of date and time of scheduled examinations. IHE-EU Conference Workshop

4. Value Proposition • Provides a mechanism for the Order Placer to keep track of appointments scheduled for a patient within Radiology Department • Includes notifications of scheduling, re-scheduling and cancellation events • Helps synchronization of scheduling processes between enterprise and radiology IHE-EU Conference Workshop

5. Background • Existing Placer Order Management Transaction allows Order Placer specify preferred date and time of an order fulfillment (i.e., radiological examination) • Order Filler is ultimately responsible for scheduling of examination as a succession of Procedure Steps that may require one or more appointments to be created • Currently, Order Placer has no way to know when or where exactly the appointment will take place.

6. Departmental Appointment Booking Use Case IHE-EU Conference Workshop

7. Appointment Notification Transaction • Department System Scheduler/Order Filler generates Appointment Notification messages and sends them to the corresponding Order Placer actor. • Order Placer receives Appointment Notification messages and internally processes them. IHE-EU Conference Workshop

8. Interaction Diagram IHE-EU Conference Workshop

9. Appointment Notification Transaction • Three typical use cases • New booking: initial scheduling of an examination • Re-schedule: change in date/time of examination • Cancellation: examination cancellation • Mechanism • HL7 SIU messages • One message may convey multiple appointments corresponding to a single order • One appointment corresponds to one or more Scheduled Procedure Steps IHE-EU Conference Workshop

10. SIU Message Structure IHE-EU Conference Workshop

11. SCH Segment • Specifies common information for one or more appointments associated with single order • Placer Appointment ID is not used • Filler Appointment ID is required • Appointment timing is defined on the Resource Group level, per Scheduled Procedure Step • SCH-6 has fixed value of 1 • One message can have multiple resource groups, thus multiple appointments (procedure steps) • No patient identification information is required, thus Order Numbers are required IHE-EU Conference Workshop

12. SIU Message Structure IHE-EU Conference Workshop

13. AIS Segment • Specifies Procedure Code and Description to for the Scheduled Procedure Step(s) included into this appointment • Procedure Code in components 1-3 • Not all steps of the procedure may be included • Those included are identified by a the text in component 5 • Date/Time of an appointment is expected to be in UTC • If local, UTC offset is required • No specification of location or resources (one should use AIG, AIL, AIP segments within the same group, as appropriate) IHE-EU Conference Workshop

14. What is not in the option • Departmental Appointment Notification Option does not allow Order Placer to request re-scheduling – it only can do it by cancel and re-order • Transaction does not require AIL segment – thus notifications on re-scheduling of the service from one location to another may not be sent • This option does not address needs of enterprise-wide scheduling IHE-EU Conference Workshop
