  1. GELLO v1 update ballot Andrew McIntyre Medical-Objects Australia GELLO 1.1 Update

  2. GELLO 1.1 • Existing Standard has errors • BNF broken • Some Examples incorrect • Missing Information • Requires update for interoperability • New BNF has been developed • Supports almost all existing Examples • Minimal change to Normative Text • Similar to OCL 2.0 (with extensions and deletions)

  3. GELLO • Background • Grew out of GLIF development • “Guideline execution language Object Orientated” • Can be used instead of curly braces in Arden • Can be used stand alone • Cannot change EHR, safe to execute • Lacks ability to perform dangerous operations

  4. GELLO Examples

  5. Real GELLO

  6. Real GELLO returns values

  7. Terminology Support

  8. CTS Access

  9. GELLO needs vMR • “Virtual Medical Record” • Simplified view of the RIM • Not specified by GELLO standard

  10. Many possible uses • Data access for ARDEN syntax • Criterion specification • Message validation • Calculated values • Visibility/validation in editors • GLIF/Other Guidelines • Assessments and scales • Eg CDAI, eGFR, GCS

  11. Further Work • Interface to vMR is loose currently • Needs to be well described for compiler • Compiler can read from idl or HL7 “ocl” • Implementation of vMR • Can be implemented with services • Can be implemented with direct access • Database • Messages (eg CCD/Query) • Subject of further independent work
