An integrated web application suite for developing, testing, and publication of CQL (Clinical Quality Language) and FHIR-based artifacts using classical IDE concepts and modern AI-assisted drafting.
Current Key Features
Environment Profile Support
Support for multiple, runtime-switchable CQL execution configurations.
FHIR Data Integration
Seamless integration with FHIR servers for data retrieval and resource management.
FHIR Terminology Clipboard
Put terminology and data references into an application-wide clipboard for insertion into CQL and Measures.
CQL Engine Testing
Comprehensive testing suite with support for multiple CQL engines and compatibility validation.
VSAC Integration
Search and import terminology value sets direct from the Value Set Authority Center (VSAC).
Docker Ready
Easy deployment with Docker containers for consistent development and production environments.
An IDE for CQL and FHIR
Powerful, user-friendly interfaces for FHIR Measure, CDS, and computable guideline development.
CQL IDE with Execution
Full-featured integrated development environment with syntax highlighting and execution capabilities.
Code Outline & Navigation
Advanced code navigation with outline view, ELM translation, and intelligent code structure analysis.
Patient Context Selection
Select example patients from imported FHIR bundles to run CQL libraries in realistic clinical context.
ValueSet Peek
Inspect terminology referenced in CQL without leaving the editor, including right-click context actions.
AI-Assisted Drafting
Optional BYOLLM assistance in the IDE—draft, explain, and refine CQL against libraries already open in the editor.
IDE AI Assistant
Chat with your own model from the IDE AI tab while authoring CQL, with the active library in context.
Examples and FHIR Import
Built-in Lipid Management and other examples with value sets, test patients, and executable CQL libraries.
Learning Library Examples
Hands-on CDS example with PREVENT-aligned cardiovascular risk utilities and VA/DoD lipid guideline logic.
FHIR Registry Importer
Import FHIR packages—including example patient bundles—into your configured FHIR endpoints.
FHIR Uploader
Upload FHIR resources and CQL libraries directly to your terminology and data servers.
Terminology Browser
Browse imported and server-hosted value sets, code systems, and concept maps.
VSAC and Terminology Workflows
Built-in optional U.S. Value Set Authority Center (VSAC) integration for instant terminology search and import.
Value Set Search
Find published value sets for use in your measure, CDS, and guideline logic using your free VSAC API key.
Import and Use
Recursively import value sets into CQL Studio and paste syntactically references into your CQL via the app clipboard.
Export Wizard
Package CQL libraries, value sets, and dependencies for download or deployment—including FHIR NPM packages.
Choose Export Destination
Start the export wizard by choosing zip archives, FHIR NPM packages, or copy-to-environment workflows.
FHIR NPM Package Export
Review dependency analysis and package metadata before building a conformant FHIR NPM `.tgz` export.
Team Collaboration and Settings
Shared workspaces, team dashboards, and environment configuration for multi-user CQL development.
Team Dashboard
Activity trends, actor summaries, and audit logs across shared workspaces.
Team Workspaces
Organize projects and shared FHIR environments with linked libraries and resources.
Environment Configuration
Configure FHIR endpoints and deployment targets for local and hosted environments.
Workspace Resource Links
Pin libraries and terminology to a workspace so collaborators can open them directly in the IDE.
