Quality Reporting Document Architecture. A QRDA report is a quality data report. Each report contains calculated summary data for one or more measures for a specified population of patients within a particular health system over a specific period of time. It is used as a transport (envelope).

• QRDA Category I (QRDA I) is an individual-patient-level report. It contains quality data for one patient for one or more eCQMs.
• QRDA Category III (QRDA III) is an aggregate quality report that contains quality data for a set of patients for one or more eCQMs.
