The document discusses 3M's Healthcare Data Dictionary (HDD) which aims to facilitate interoperability and information exchange between disparate healthcare systems through data standardization and centralized terminology mapping. The HDD maps terms from different systems to common clinical terminologies to allow semantic interoperability and enables reporting, public health efforts, quality metrics, research, and clinical decision support. Centralized mapping through the HDD is more easily maintained than direct point-to-point mappings between each system. The HDD provides a "Rosetta stone" to translate data into standard codes from terminologies like LOINC and SNOMED.

Point-to-Point Mapping for 9 sources = n(n-1)/2 = 36 maps
Adding 1 more source adds 9 maps
Challenge is not only in the creation, but the maintenance
all of these mappings
Mapping to a terminology server for 9 sources = n =
9 maps
Adding 1 source adds 1 map

HDD Mapping Result – Rosetta Stone
 Manages ongoing updates
from standard terminologies as
well as local additions and
changes from health care
facilities
 Translates/transforms an
enterprise’s data to standards
such as LOINC®, so it can be
interpreted by all other systems
using standards
 Moves Syntactic
Interoperability to the level of
Semantic Interoperability and
enables Meaningful Use
