CDS Hooks Interface for Hacking Health Brisbane 2017 Track 6

This page describes the interface for track 6 for Hacking Health Brisbane 2017 (see [[1]])

Basics

The cds-hook is 'order-review' - see [[2]].

Given the scenario described in the track, we assume that there's no call back to the EHR - so all data is provided via pre-fetch. Therefore, the EHR provides the following information:

• hook = order-review
• a hook instance
• a user id
• a patient
• an encounter (e.g. information about the GP consultation)
• a patient and and encounter resource matching those in the pre-fetch data
• at least one Condition - (problem list for the patient, also in the prefetch data
• one or more ProcedureRequest resources, for each test (or panel) requested by the clinician (in the context)
• no oauth/redirect details

The service returns a set of cards (no profile on the response yet).

Implementations

There's an implementation at http://test.fhir.org/r3/cds-services/hacking-health. All that implementation does is return a card that describes technical issues with the submission from the EHR.
