A recognized standard for submission of Electronic Health Record (EHR) data to support public health case reporting (PHCR) does not yet exist. This poster presentation provides an overview of the process by which CDC, in collaboration with the Council of State and Territorial Epidemiologists (CSTE), developed a Clinical Document Architecture Release 2 (CDA R2) Implementation Guide (IG) for use by the healthcare facility or provider in creating a case report to send to state and local public health agencies.
The PHCR IG using Health Level Seven (HL7) CDA format was developed to specify a standard for electronic submission of clinical documents. CDA is a recognized industry standard and facilitates interoperability. Two key characteristics of CDA are its ability to allow for human interpretation (textual) and to represent concepts (structured) pertinent to public health.
An interdisciplinary team of vocabulary and terminology experts, epidemiologists, and data modelers from CDC, academia, state public health, and HL7’s Structured Document Workgroup collaborated to develop the PHCR IG. Through the identification of non-condition-specific (relevant to all conditions) and condition-specific (relevant to specific conditions) data elements commonly associated with public health reportable condition forms across the U.S. by a working group convened by CDC’s National Center for Public Health Informatics and CSTE, the IG was assigned standard codes and values for each data element. The outcome resulted in the generic document level template with constraints that apply across all PHCR, as well as the condition specific disease templates for anthrax, acute hepatitis B, tuberculosis, and tularemia.
This effort will lead to a set of modular definitions (templates) reusable across conditions and conformant with design patterns established for EHRs and interoperable data exchange. The IG has been submitted to HL7 balloting in May 2009.
