Why LOINC and why not only LOINC?

Looking for a standard: LOINC
• Logical Observation Identifiers Names and Codes (LOINC) is a database
and universal standard for identifying medical laboratory observations. It
was developed and is maintained by the Regenstrief Institute, Inc., a US
non-profit medical research organization, in 1994.
• LOINC was created in response to the demand for an electronic database
for clinical care and management and is publicly available at no cost.
• It is endorsed by the American Clinical Laboratory Association and the
College of American Pathologist. Since its inception, the database has
expanded to include not just medical and laboratory code names, but
also: nursing diagnosis, nursing interventions, outcomes classification, and
patient care data set.
• LOINC applies universal code names and identifiers to medical
terminology related to the Electronic health record.
• Widely accepted:
– Switzerland : CUMUL (French- German- English- Italian- Spanish)
Based on LOINC 2.21 (december 2007), 5071 records
– France: CLUABM “version francisée de la nomenclature LOINC”
adopted e.g. by APHP. 4408 records
