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

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
