Category: Development, Testing

Software tool that allows eCQMinfo-icon developers to test and verify the behavior of their eCQM logic. The main goal of the Bonnieinfo-icon application is to reduce the number of defects in eCQMsinfo-icon by providing a robust and automated testing framework. The Bonnie application allows measure developersinfo-icon to independently load measures that they have constructed using the MATinfo-icon. Developers can then use the measure metadata to build a synthetic patient test deck for each measure from the clinical elements defined during the measure development process. By using measure metadata as a basis for building synthetic patients, developers can quickly and efficiently create a test deck for a measure. The Bonnie application helps measure developers execute the measure logic against the constructed patient test deck and evaluate whether the logic aligns with the intent of the measure.

The guide focuses on a set of common best practices implemented across CQL-based eCQMs in CMS reporting programs and also promotes the use of consistent language within the framework of CQL, including libraries, aliases, definitions, functions and conventions.

CQL-to-ELM Translator Reference Implementation

Category: Implementation

The HL7info-icon CQLinfo-icon specificationinfo-icon defines both a high-level, author friendly syntax for expressing clinical knowledge, as well as a machine friendly, syntax-independent canonical representation of clinical knowledge called Expression Logical Model (ELM). The high level syntax is designed to support measure and decision support authors, while the canonical representation is designed to support point-to-point sharing and machine processing applications.

The specification describes a formal mechanism for translating the high-level CQL syntax into the canonical ELM representation. This project provides a reference implementation of that translation. The translation component is designed to support use within an Integrated Development Environment (IDE), and has several options and features focused on providing translation support in such an environment. The reference implementation is intended to be used in support of CQF implementations as a tool to enable CQL output to be uniformly and automatically translated into ELM XMLinfo-icon or JSON documents for sharing and distribution to support implementation, integration, translation, and execution of CQL-based artifacts.

The CQL-to-ELM Translator is substantially complete, supporting all language constructs of the latest version of CQL (Release 1 STUinfo-icon 2 (1.2)), as well as a broad range of functionality to support use of the translator in an Integrated Development Environment. Implementations making use of the translator can submit issues and track resolution progress through the Issues tracker in the Github repository.

Guidance for reporting diagnostic test data in the Diagnostic Study Performed (V4) template of QRDA Category I files

Category: Reporting
Who Uses Tool: Eligible Hospital

The Centers for Medicare & Medicaid Services (CMS) and The Joint Commission (TJC) released guidance for reporting diagnostic test data in the Diagnostic Study Performed (V4) template of Quality Reporting Document Architecture (QRDA) Category I files. This affects the electronic clinical quality measureinfo-icon (eCQMinfo-icon) CMS31v6 - Hearing Screening Prior To Hospital Discharge only. The 2018 CMS QRDA Category I Implementation Guide (IG) for Hospital Quality Reporting allows for two ways of reporting the result of a diagnostic test in the Diagnostic Study Performed (V4) template:

  1. Using the element “value” inherited from its parent template Procedure Activity Observation (V2), or
  2. Using the contained template Result Observation (V3).

For 2018 reporting, CMS has aligned with TJC to only use the first option. Result data for the Diagnostic Study Performed template must be in the value element in order to be processed by CMS.

Result data provided in the template Result Observation (V3) will not be used by the QualityNetinfo-icon data receiving system during measure calculation of CMS31v6. The QRDAinfo-icon file will not be rejected, nor will a warning be returned, if the Result Observation (V3) template is used, and that the measure outcome of CMS31v6 from CMS may not match what is expected.
