Notice: Additional Consolidated Health Informatics (CHI) Health Information Technology Standards.

SUMMARY:

This notice identifies three (3) additional Consolidated Health Informatics (CHI) messaging and vocabulary standards (Multimedia, Allergy, and Disability and Assessments) adopted for use in Federal government health information technology systems. This work supplements the work to further the adoption of the first set of 5 standards adopted on March 21, 2003 and second set of 15 standards adopted on May 6, 2004, as published in the December 23, 2005 Federal Register (70 FR 76287).

The CHI initiative began in October 2001 as one of 24 E-Government initiatives included in the President's Management Agenda (PMA). The CHI collaborative worked to adopt Federal government-wide health information interoperability standards to be implemented by Federal agencies in order to enable the Fedral government to exchange electronic health information. By publication of this document, we are informing the public of the adoption of three new CHI standards, Multimedia, Allergy and Disability and Assessment (adoption reports available at: www.hhs.gov/​healthit/​chiinitiative.html).

CHI Adopted Standards

As a result of work completed in furtherance of CHI, the three new domain areas and associated clinical standards that have been adopted are noted in the individual standards adoption reports found at www.hhs.gov/​healthit/​chiinitiative.html and are summarized below:

1. Multimedia Messaging Standard:

• National Electrical Manufacturer's Association (NEMA) Digital Imaging and Communications in Medicine (DICOM^SM) 2004 Standard and higher.

2. Allergy Messaging and Vocabulary Standard:
