Presentation Transcript

  1. GLIF – GELLO – Archetypes Jared Davison Medical-Objects Australia

  2. Key Points • GLIF and GELLO implementation using Lymphoma as the clinical example • Arden was considered but GELLO felt to be better fit • GELLO was Object-Oriented • Interface with data model • vMR rather than use curly braces • Closely related to Object Constraint Language (OCL)

  3. Key Points • GLIF chosen as guideline representation language • Inspiration for GELLO • Specific lacking detail, specifically no structures to accommodate GELLO • GELLO specifications had not been implemented • Significant errors and lacked required features • eg no standard way of passing parameters to GELLO and no formal definitions of GELLO libraries

  4. Key Points • Contact with GELLO authors and researchers • Raised issues for inclusion in second ballot of GELLO

  5. Key Points • GELLO requires a VMR for access to patient data • Lack of specifications for vMR • Created abstraction of HL7 v2 model • Could be represented as v3 • Used Archetype Definition Language (ADL) to define data structures for user data-entry • Encoded in HL7 v2 OBX using an experimental technique • Enables re-use and re-editing of data • Also used for decision support
