The Measure Authoring Tool (MAT) is a web-based tool that allows measure developers to author electronic Clinical Quality Measures (eCQMs). Using the tool, authors create Clinical Quality Language (CQL) expressions, which have the conceptual portion of the Quality Data Model (QDM) as their foundation. The tool provides the capability to express complex measure logic and export measures in several formats, including a human-readable document that can be viewed in a web browser, an eCQM HQMF XML document which provides metadata, terminology, data elements and specific population definitions respective to the measure, a CQL file which contains the terminology and expression logic used by the measure, an ELM XML export that is a computer-readable XML version of the CQL file, and a Javascipt Object Notation (JSON) export which is a serialized format of the ELM file. The data expressed in the tool by the users serves as the input for the creation of the defined export files.
