QDM

The Quality Data Model (QDM) is a conceptual information model that defines clinical patient data and concepts in a standardized format to enable electronic quality performance measurement.  It defines key information concepts (Categories), the context (Datatype) in which the category is used (e.g., performed, ordered), and their details (Attributes) (e.g., relevantPeriod, result). The model is the current structure for electronically representing quality measure concepts for stakeholders involved in electronic quality measure development and reporting. Electronic health record systems can use the QDM to consistently understand the information to access from clinical records to report the data required to meet measure criteria.
