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:

2021 Release XPath - 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.

MeasureID tab - provides the measure IDs and OIDs of the eCQMs supported by The Joint Commission for CY2021 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.

This combined with the  Error and warning messages provides the entire list of edits being evaluated against the documents.

The Conformance Number for each rule is provided within the schematron document.  These Conformance Numbers are available within Source Viewer to assist in tying error and warning messages back to the schematron rule.

There are three types of conformance statements with different formats for the CONF number:displayed.

·       Joint Commission CONF numbers (TJC-xxxxxx)

·       CMS CONF numbers (CMS_xxxx_xxxx-C01 or xxxx_xxxx-C01)

·       HL7 Clinical Document Architecture (CDA) QRDA Category I Errors (xxxx_xxxx). 

o   Please note that HL7 Conformance numbers are not prefixed with "HL7".  All Conformance numbers without the prefix of "TJC" or "CMS" or a suffix of "C01" are HL7 Conformance numbers.

For more information concerning CMS or HL7 Conformance numbers, see the below reference material:

·       CMS:  Visit the eCQI Resource Center CMS QRDA IG publication page for the documents associated to this year's data.

·       HL7: Visit the HL7 website to obtain the version of the HL7 CDA® R2 IG: QRDA I applicable for this year's data.

·       The HL7 website may require a HL7 account in order to download the Implementation Guide (IG).

o   The HL7 website header states the current Release number.  Scroll to the bottom of the page to find the Release that is appropriate for this calendar.
