Galen Healthcare Solutions: Allscripts Consultants Enterprise EHR » HL7 & Meaningful Use Hands-on Workshop: CDA R2 track. Ever wonder who designs and develops Health Level 7 (HL7)? Well HL7 international is based out of Ann Arbor, Michigan and they hold various workshops around the country. I recently had the chance to attend the HL7 Education Summit at the Hilton Suites Chicago Magnificent Mile over March 15th and 16th, 2011. (All images and information were taken from HL7 Educational Summit presentations).

The Clinical Document Architecture (CDA) second release (R2) workshop was a very informational, hands-on experience. CDAs don’t replace v2.x HL7 field delimited messages, and instead compliment them. CDAs are very informational and pack a lot of information. CDA v2.x HL7 field delimited message CDA Resources CDA’s can be used not only as a CCD (Continuity of Care document), but to send lab results, immunizations, allergies, and much more! A great tool to build CDAs is MiniCDA, you may be able to find it online. On Demand CCDs: Continuity of Care. At Axolotl, we dynamically generate template based CDA documents from various data sources. One commonly transmitted document is the CCD, or Continuity of Care Document. This is a summary document, its intended purpose to have enough information, well organized, to preserve the continuity of patient care between different care providers. The way I approach template-based CDA is to first look at the document as a container for health data, and construct the empty container first.

You can see it has, first, the necessary meta-data. Source, destination, attribution, author, the time period this document covers, any confidentiality instructions, and other information about this document. Then it has the patient demographics and a list of all healthcare providers involved in the care described, and all doctors who provided care during the covered period. The largest part is the clinical information itself. NwHIN Connections - Direct Project Basics. Direct Project - home. NCHICA. Everyone is asking, “What is NwHIN Direct we keep hearing about, and how does it differ from the original NwHIN Exchange?”

NCHICA follows the development of the NwHIN closely; the article below provides an updated description of these initiatives, and how they will impact providers and healthcare organizations. Before we dive into NwHIN Direct, we need to review the "NwHIN Limited Production Exchange" (ONC's formal name for it.) In this article we’ll refer to it as "NwHIN Exchange. " The NwHIN Exchange is a collection of standards, protocols, legal agreements, specifications and services that enables the secure exchange of health information over the internet. The NwHIN Exchange has methods to perform universal patient lookup, document discovery and retrieval, and exchange between organizations and federal agencies (VA, DOD, CDC, SSA, plus 22 others). The organizations entering into an exchange with those federal agencies are typically sizable HIOs, HIEs or large IDNs.
