Proposal: add Find Appointments Query

Summary

This proposal seeks to add a new query interaction to the Appointment topic of the Scheduling (PRSC) domain.

The new Find Appointments Query (PRSC_IN010701UV) queries the Appoint Manager for apppintments that match a set of criteria (e.g. the time of the appointment and the resources associated with the appointment) as specified in the query parameters. The intent and underlyinh use-cases are the same as those for the HL7 version 2 SQM/SQR - Schedule Query Message and Response (Event S25) (up to version 2.6; now deprecated and moved to chapter 5).

Use-case

Helse Vest, the western region of Norway has a use-case whereby:

1. (covered by a different proposal) They use a Find Encounters query to find out (e.g.) who is currently sitting in the waiting room in Building X. For all patient IDs returned in the response:
2. Query the appointment manager to find appointments for a given Patient ID and a particular resource (e.g. the ID of a particular piece of equipment).

Helse Vest has identified the following query parameters as being of importance for their particular use-case:

• Patient.id (mandatory)
  • ActAppointment/subject/Patient(PAT role).id
• Physician.id (as scheduled)
  • ActAppointment/performer/AssignedPerson(role).id
• Equipment.id (as scheduled)
  • ActAppointment/reusabledevice/ManufacturedDevice(role).id
• Ward/room (as scheduled)
  • ActAppointment/Location/R_ServicedeliveryLocation/ xxxx?
• Clinic (as scheduled)
  • ActAppointment/Location/R_ServicedeliveryLocation/ xxxx?
• Encounter.code (as scheduled)
  • ActAppointment.code
• Time/date (of the scheduled encounter)
  • ActAppointment.effectiveTime
