CDS Hooks Walk-through

Introduction

CDS Hooks is a technology from SMART on FHIR that allows third-party CDS systems to register with an EHR using a "hook" pattern. The third-party CDS system is able to provide the EHR with information in the form of "cards" that the EHR may use to show the end-user or otherwise interweave into the workflow. The Logica Bilirubin system is able to use CDS Hooks to alert the EHR of babies that are at risk of Kernicterus.

Prerequisites

Patient and observation data must be loaded into the EHR (see hspconsortium/bilirubin-cdshooksadapter/src/main/resources/himms-notes.txt)
- See datapack dstu2/usecases/cds-hooks.fhir-bundle.xml
- Birthdays must be for one day prior to the current date
- Observation effective date must be the same as the current date

Example Using the Logica Bilirubin System

SMART on FHIR Test Harness

STEP 1

Launch the SMART on FHIR Test Harness at http://hooks.fhir.me/

STEP 2

Enable the Bilirubin Patient View hook (hint: search for "bilirubin", select Configure Hooks again to close)

STEP 3

Select Patient View. This represents an EHR patient view screen "action"

STEP 4

Observe the default patient (not a baby) sees no Bilirubin Card

STEP 5

Select Change Patient and enter value of "ID-BabyWithoutBilirubinObservation"

STEP 6

Observe a Bilirubin card is returned to the EHR stating that the baby has no bilirubin observations

STEP 7

Select Change Patient and enter the value of "ID-BabyWithBilirubinObservation"

STEP 8

Observe a Bilirubin card is returned to the EHR stating that the baby has a bilirubin level that exceeds thresholds.
