Capability statement for a service supporting CQL evaluation use cases

The $cql operation evaluates a CQL expression and returns the result. The operation has a single return parameter that can be of any type to accommodate the possible result types of a CQL expression.

Evaluates the contents of a library and returns the results as a Parameters resource.

This library defines terminologies and functions commonly used in FHIR-based CQL artifacts.

This library defines functions to convert between FHIR data types and CQL system-defined types, as well as functions to support FHIRPath implementation. For more information, the FHIRHelpers wiki page: https://github.com/cqframework/clinical_quality_language/wiki/FHIRHelpers

This library defines test cases for FHIRHelpers functionality

Model definition for the FHIR R4 (v4.0.1) Model

The CQL Capability Statement Profile enables capability statements to express supported CQL versions.

The CQL Evaluation Result profile supports using the dataAbsentReason extension to indicate null evaluation results from operations.

Supports the description of model info configuration information as part of an implementation guide

The CQL Library profile defines conformance expectations for the use of a FHIR Library resource as a wrapper for a Clinical Quality Language (CQL) library

The CQL Model Information profile supports the FHIR representation and distribution of CQL ModelInfo such as the FHIR Model Info Library

CQL ModelInfo settings expressed using FHIR Parameters

The CQL Module profile describes the elements used to provide a structured representation of the declarations and data requirements of a logic library or operation

A parameters profile that defines supported CQL-to-ELM translator options used to translate CQL. Complete documentation of these options can be found in the Usage topic of the CQL-to-ELM translator overview.

Supports configuration of model info information for a StructureDefinition

The ELM Library supports distributing a Clinical Quality Language (CQL) library compiled to Expression Logical Model (ELM) in JSON format

The ELM CQL Library supports distributing a Clinical Quality Language (CQL) library compiled to Expression Logical Model (ELM) in XML format

Example cohort definition for anteantal care

Example CQL Library illustrating the CQL Profile (a Library with only text/cql content)

This code system contains example content used to support examples in the Using CQL IG

This implementation guide demonstrates the use of modelinfo settings

Before each contact, the health worker should check whether the woman has any of the danger signs listed here – if yes, she should refer to the hospital urgently; if no, she should continue to the normal contact

Example ELM library demonstrating the ELM XML and ELM JSON profiles (a CQL library with only ELM)

Example CQL Library used to demonstrate common patterns used in CQL with FHIR-based models

Example Parameters resource demonstrating the use of the CQLOptions profile to specify CQL translator options. This resource would typically be a contained resource in an implementation guide, artifact collection, or library.

Codes representing possible values for the Danger Signs - Central cyanosis element

Codes representing possible values for the Danger Signs - No danger signs element

Codes representing possible values for the Danger signs element

Group Valueset with codes representing possible values for the Danger signs Codes Grouper element

Example Parameters resource demonstrating the use of data-absent-reason extension to indicate a null evaluation result.

This library is used as an example module definition in the Using FHIR with CQL Implementation Guide

Example Parameters resource demonstrating the use of ModelInfo configuration parameters. This resource would typically be a contained resource in an implementation guide or artifact collection.

Example Observation resource illustrating negation and the use of the notDoneValueSet extension.

Example Patient resource used as part of the observation negation example.

Codes representing possible values for the Specific health concern(s) element

Example Parameters resource showing the result of evaluating the TypeMappingExample library, demonstrating all possible CQL-to-FHIR type mappings.

Basic conformance statement for a Library Evaluation Service. A server can support more functionality than defined here, but this is the minimum amount

Example CQL library with a parameter defined, used to illustrate calling the $cql and Library/$evaluate operations with libraries that have parameters

If the woman came to the facility with a specific health concern, select the health concern(s) from the list

Example CQL library providing a complete set of expressions that cover all possible CQL and FHIR Type Mapping, for both input and output. See the Type Mapping Evaluation Result example for an illustration of the type mapping in a Parameters resource.
