Purpose

Below are the XPath navigation and schematron rules executed by the DDSP Rule Engine against each uploaded QRDA I Document.

It is expected that information technology staff or staff familiar with XPath navigation and schematron rules experience be available to use this documentation.

XPath Document

XPath stands for XML Path Language and uses a "path like" syntax to identify and navigate nodes in an XML document.  XPath is a W3C recommended standard utilized by HL7. 

The Joint Commission's XPath and Measure OIDs Document is being provided to assist software developers in understand where the DDS Platform is expecting data to exist within the QRDA I Document. There are three Tabs within the document. They are:

• 2023 Release xPath tab - contains the xPath which is used to find or map the location of each element within a QRDA I document. The “Key Table” section at the bottom of this tab makes the mapping more readable, the Key Table provides the XPath for the corresponding sections. Replace {SectionName} with the Section xPath on the Key Table. Then parse the resulting path and return the data from the parameters given in the @ part.

• msrcattyp tab - provides the crosswalk the eCQM measure results and the chart-abstracted measure category assignments.

• MeasureID tab - provides the measure IDs and OIDs of the eCQMs supported by The Joint Commission for CY2023 Reporting.

• Inpatient Tab - provides the Inpatient OIDs

Schematron Rules

“Schematron” is a rule-based validation language for making assertions about the presence or absence of patterns in XML trees. It is a structural schema language expressed in XML using a small number of elements and XPath.

The Joint Commission’s starts with CMS' schematron for any given year’s eCQM data submission. In turn, CMS starts with HL7' schematron associated to the version of the QRDA I IG for that year’s data.

The Joint Commission’s Schematron Rules are being provided to assist software developers in understanding how the DDSP validates uploaded QRDA I documents. The zip file contains a ‘.sch' file and may be opened in Notepad or another application that is able to open this type of file.
