HL7 Quality Reporting Document Architecture (QRDA) is a standard for communicating health care quality measurement information. There are 3 basic types of QRDA documents,  Category I and Category III being the most popular, as these two are often asked for testing and validation over cypress and other testing tools. Below are brief definitions of these from the HL7 documents.

 

QRDA Category I – Single Patient Report

A QRDA Category I report is an individual-patient-level quality report. Each report contains quality data for one patient for one or more quality measures, where the data elements in the report are defined by the particular measure(s) being reported on. A QRDA Category I report contains raw applicable patient data. When pooled and analyzed, each report contributes quality data necessary to calculate population measure metrics.

 

QRDA Category II – Patient List Report

A QRDA Category II report is a multi-patient-level quality data report. Each report contains quality data for a set of patients for one or more quality measures, where the data elements in the report are defined by the particular measure(s) being reported on.
QRDA Category I report contains only raw applicable patient data, while a QRDA Category II report includes flags for each patient indicating, whether the patient qualifies for a measure’s numerator, denominator, exclusion, or other aggregate data element. These qualifications can be pooled and counted to create the QRDA Category III report.

 

QRDA Category III – Calculated Report

A QRDA Category III report is an aggregate quality 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.
