Real-Time Clinical Pathway Monitoring via FHIR Event Subscriptions Tutorial

Tutorial Topic

Automating Clinical Pathway Compliance: Building an Event-Driven Exception Management System in IRIS for Health

Learning Objectives

By the end of this tutorial, the learner will be able to:

• Configure FHIR Subscriptions: Set up a Subscription resource in the IRIS FHIR Repository to trigger an action whenever a MedicationRequest, Observation (Lab), or Procedure is created.

• Develop a Custom Business Process: Create a BPL (Business Process Language) workflow that calculates "Hospital Day (HOD)" by comparing the current date against the FHIR Encounter admission date.

• Implement Clinical Logic via Rules Engine: Build a Business Rule Set that evaluates specific compliance criteria (e.g., "If HOD=1 and no Anti-coagulant medication is found, trigger alert").

• Integrate External Notifications: Configure an Outbound Adapter to send the "Exception Alert" to an external service like Microsoft Teams (via Webhook) or an interactive form.

• Query FHIR for Context: Use the internal FHIR specialized classes to "pull" additional patient context (like Comorbidities/Conditions) to refine the rule logic.

Target Audience

• Clinical Informaticians: Who understand the medical pathway logic but need to know how to digitize it.

• Health Solution Architects: Looking to implement "Active" FHIR architectures rather than "Passive" storage.

• IRIS Developers: Who are familiar with Ensemble/Interoperability but are new to the FHIR-to-Production trigger mechanism.

Value of this Tutorial

Most FHIR tutorials stop at "How to save a resource." This tutorial addresses the high-value "Last Mile" of healthcare IT:

1. Efficiency: Replaces manual daily audits with real-time, automated "exception-only" reporting.

2. Patient Safety: Ensures critical medications or labs aren't missed during specific windows of the surgical pathway (e.g., Joint Surgery Day 0-2).

3. Scalability: Shows how to use the IRIS Rules Engine, which allows non-coders (like Lead Nurses or Quality Officers) to update the pathway logic without redeploying code.
