  • Title: A logical approach to semantic interoperability in healthcare.
    Author: Bird L, Brooks C, Cheong YC, Tun NN.
    Journal: Stud Health Technol Inform; 2011; 168():1-9. PubMed ID: 21893905.
    Abstract:
    Singapore is in the process of rolling out a number of national e-health initiatives, including the National Electronic Health Record (NEHR). A critical enabler in the journey towards semantic interoperability is a Logical Information Model (LIM) that harmonises the semantics of the information structure with the terminology. The Singapore LIM uses a combination of international standards, including ISO 13606-1 (a reference model for electronic health record communication), ISO 21090 (healthcare datatypes), and SNOMED CT (healthcare terminology). The LIM is accompanied by a logical design approach, used to generate interoperability artifacts, and incorporates mechanisms for achieving unidirectional and bidirectional semantic interoperability.
