Define Healthcare Standards with Smile at HL7^® FHIR^® Dev Days 2026

With James Agnew, Gino Canessa, Grahame Grieve, Ewout Kramer, Lloyd McKenzie 

Audience-led Q&A with experts. 

with Bryn Rhodes

There are hundreds of published HL7 FHIR Implementation Guides, each with their own set of required value sets and code systems. Each of those thousands of value sets have dependencies on external code systems that publish on their own cycles. Keeping terminology current in this environment is a constant challenge: Value Set Packages help address that challenge by allowing editors and implementers to regularly update their terminology without the need to republish implementation guides. Attendees will learn how to use the Value Set Package Manager to create and download terminology

Welcome to the Student Track at FHIR DevDays 2026! In this kick-off session, you will receive all the essential information about the schedule, meet the jury, and hear tips for making the most of your DevDays experience. Participating teams will be announced at a later stage.

CQL can be used to share clinical logic across use cases like measures and decision support rules. This session will cover technologies and patterns that improve reusability of CQL content, including derived model info, polymorphic fluent functions, and terminology practices. Attendees will learn what shared libraries are already available, how to contribute to those, as well as how to build and share reusable CQL libraries of their own.

NCQA HEDIS reporting is more than just numerators and denominators; reporting the full set of measures requires sophisticated quality reporting capabilities, including multi-component stratifiers, capturing and reporting supporting evidence, and risk-adjusted measures. This session will demonstrate how FHIR and CQL are being used to implement these advanced capabilities of HEDIS measures. what shared libraries are already available, how to contribute to those, as well as how to build and share reusable CQL libraries of their own.

This presentation describes a real-world implementation of AI-assisted authoring for FHIR Clinical Reasoning artifacts, including PlanDefinition, ActivityDefinition, Library, and CQL. The approach combines large language models with strict FHIR, CQL, and terminology constraints to accelerate guideline transformation while preserving determinism, traceability, and conformance. We will walk through an implementation supporting digital quality measures and care pathway authoring. The session focuses on architectural patterns, validation strategies, human-in-the-loop workflows, and lessons learned integrating AI into regulated clinical reasoning pipelines. Measurable outcomes include reduced authoring time.

Building a standards-based approach for interactive CDS experience is an experimental but maturing feature on the roadmap of the CPG IG. This talk aims to provide a solution and implementation details for gathering and verifying computable data required to provide patient specific clinical guidance. We will also demonstrate an end-to-end app that implements the workflow.

A presentation on using the Clinical Practice Guidelines Implementation Guide and the PlanDefinition $apply operation in support of CMS-0057-F. See how the CPG approach enables reuse across use cases, including prior authorization support.

with Bryn Rhodes

WHO SMART Guidelines provide a complete, FHIR-based computable representation of guideline recommendations and indicators, streamlining digital implementation. This session will introduce the CPG Runner, an Android application built with Kotlin Multi-platform CQFramework and Open Health Stack components that can natively run WHO SMART Guideline content. Attendees will learn how to configure and deploy the application using any published WHO SMART Guideline.

with James Agnew

The HAPI FHIR changelogs often refer to the "Batch2" framework, which is the way HAPI managed and executes long-running jobs. While we often talk about this framework, how it works can be mysterious. This talk dives deep into the guts of the framework to help explain how the framework works. We'll also explore some batch jobs you know about (e.g. Bulk export) and some you may not know about too (Bulk Patch anyone?)

A presentation on building Questionnaires with CQL Libraries and using them with the SDC $populate operation. Focusing on the Da Vinci Prior Authorization Burden Reduction DTR use case and building blocks for broader use cases.
