What is the Quality Data Model (QDM)?

The Quality Data Model (QDM) is an information model that defines relationships between patients and clinical concepts in a standardized format to enable electronic quality performance measurement. The model is the current structure for electronically representing quality measure concepts for stakeholders involved in electronic quality measurement development and reporting. The QDM is currently being aligned with other relevant clinical decision support (CDS) standards.

The QDM provides the language that defines the criteria for clinical quality measurement. It allows the electronic definition of a clinical concept via its data elements and provides the vocabulary to relate them to each other. By relating attributes between data elements and using filtering functions, the QDM provides a method to construct complex clinical representations for electronic clinical quality measures. The QDM provides the foundation for the conceptualization and specification phases in the eCQM Measure Lifecycle.
