International Interoperability through unified universal HL7 v3 Green Messaging

Health Level Seven (HL7) is the most popular, global healthcare standard in use today. Introduced in 1987 by the HL7 International Inc., the current version 3 has been promoting Semantic Interoperability (SI) which is two or more computer systems exchanging valued healthcare information with homogenous understanding. Thus, efficient implementation for optimal, high-end SI entails the abridgement of verbose v3 Message paradigm representations, whilst strictly maintaining their semantic nuance and flavour. The resulting economised structures termed Green Messages, have to be truly universally overarching, affording and facilitating International Interoperability. Aligned with this core Greening requirement is the demand for secured, efficacious exchange of data and information “in the wire”, promoting overall efficiency. This paper outlines conclusive research on all greening fronts, and underscores sound methodologies to realize true International Interoperability and superlative efficiency, as appraised by the ten, archaic System Performance Indicators (SPIs) used.
