6 things to know about Consolidated CDA

Recently, Rob Brull, product manager at Corepoint Health, outlined five things to know about CCD, the standard for Stage 1 Meaningful Use. And now, we looked to Brull to explore Consolidated CDA, a type of CCD document in the proposed Meaningful Use Stage 2 guidelines for the exchange of clinical health data.

Brull answers five questions about Consolidated CDA.

1. Why Consolidated CDA? With CDA and, specifically, CCD, a specific document within the CDA standard, there were "many sources of truth," said Brull. "For example, in meaningful use Stage 1 rules, the document standard referenced was C32, which is a constraint of the CCD document defined by Health Information Technology Standards Panel (HITSP)," he said. Essentially, this was HITSP's version of CCD. "So, to understand the full meaning of C32, a user would have to traverse documentation from HL7 and HITSP," said Brull. He added there were other organizations with constraints too, like Health Story for Integrating the Healthcare Enterprise (IHE). "Consolidated CDA aims to organize all the documentation in one place."

2. What is the ‘Consolidated’ part of Consolidated CDA? According to Brull, "consolidated" refers to the development of a single implementation guide that he says can be the single source of truth. "It represents harmonization of Health Story guides, HITSP C32, part of the IHE Patient Care Coordination, and the original CCD by HL7," he said. "The Consolidated CDA implementation guide defines templates used to structure the document." With one implementation guide – and all the templates – defined in one place, the standard becomes easier to analyze and implement, he added.

3. How are templates used in the Consolidated CDA standard? The Consolidated CDA implementation guide contains a library of CDA templates, said Brull. "These templates originate from HL7, IHE and HITSP. The templates are defined at three levels: document, section and entry," he said. The document level templates define the type of CDA document, like CCD. The section level templates define how data within specific sections will be structured, like vital signs. "Thus, vital signs will be structured the same in a CCD document as compared to a History and Physical document, with no need to recreate the wheel for different documents," he  added. "Entry-level templates define how specific observations, procedures, etc. will be structured, making entries appear the same no matter what document or section they are a part of."

4. How many different types of documents are included in Consolidated CDA? The Consolidated CDA implementation guide defines nine different types of commonly used CDA documents, said Brull, including:
