Scheduling Booked

This data model communicates information about a patient’s office or other outpatient appointment. EHR systems can send Scheduling messages to update your system with the appointment status, date/time, scheduled providers, and scheduled resources.

Every appointment gets assigned a visit number and patient ID. Any changes to the appointment are made with the relevant visit number. If the appointment is canceled and later rescheduled, however, a new visit number is created. Also keep in mind that scheduling holds and blocks don’t have an associated patient ID.

This data model has event types that allow you to:

  • receive a notification about appointment updates;
  • push or receive a list of available appointment slots;
  • query for and receive open appointment times; or
  • query for and receive booked appointment times.
EHR support for Scheduling

EHR systems typically make scheduling information available through either a standard SIU HL7v2 feed or a proprietary API. SIU messages follow a push notification model while a proprietary API and web service rely on queries.

You also have the option to use data on demand if you prefer to query, but your connection only supports push notifications for scheduling data. For example, if you primarily want information about a booked appointment, you can use the Booked event type to get the information you need with data on demand. Learn more about data on demand.

Scheduling vs. SurgicalScheduling vs. PatientAdmin data models

There’s some overlap among these data models, but here’s what to expect for each:

  • The Scheduling data model contains information about outpatient appointments. This may include pre- and post-op office appointments.
  • The SurgicalScheduling data model contains information about surgical appointments. This contains information besides appointment details, like questionnaire answers from the patient, equipment requirements for the procedure, or in-progress notes about the surgery.
  • The PatientAdmin data model contains insurance information for appointments or surgical procedures.

Booked

Query for booked times within a given time range. Results are returned in Scheduling.BookedResponse.

Required query parameters and populated response

The required elements and populated response vary depending on the EHR system you're integrating with. Work with your connection to understand which query parameters they require and what to expect in the response during implementation testing.
