The health standard Health Level 7-Service-Aware Interoperability Framework
(T1L7-SAIF) is the most popular and widely-used healthcare-related standard in global
operation today. Originally introduced as HL7 in 1987 and recently melded with the SAIF
technology, the standard has been embraced by the National Health Services of the most
developed economies in Europe, North and South America, and Australasia.
However, the standard is not without issues. Its current version v3 which supports
Semantic Interoperability, the overarching and meaningful exchange o f healthcare
information amongst participating healthcare enterprises, has been found to be difficult to
implement and maintain. A principle component of the HL7-SAIF v3 development paradigm
is the recently integrated SAIF component which presents a significant and worrisome
element of ambiguity. These issues in essence subvert quality specifications development,
which permeates to difficult system implementation and sub-standard performance in
operation.
This research analysed many o f the prevalent SAIF issues indepth, and effected smart,
delicate, and prudent refactoring o f this principle semantic interoperability driver, to derive
optimal efficiencies in specifications development and implementation.
