Dec 14, 2014
1. Background, Definition and Purpose
a. Background – A Data Access Framework using IHE Profiles Whitepaper <link>
b. Definition - What is Document Metadata based access? Document Metadata based DAF
Queries are created using the metadata associated with clinical documents. The
metadata associated with clinical documents is typically captured as part of clinical
workflows. Examples of metadata include:
i. Type of the clinical documents (for e.g. Office Visit Summaries, Discharge
Summaries, Operative Notes, History and Physical notes) used to record various
clinical encounters.
ii. Patient identifier information such as patient id or medical record number.
iii. Metadata such as time of creation, modification time, Practice Type, and other
ebRS/ebRIM based metadata
c. Purpose – For the United States, create an implementation guide for the Document
Metadata based DAF Queries covered in the “A Data Access Framework using IHE
Profiles Whitepaper” published in 2014 taking into account updates and expansions of
IHE profiles
