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

GELLO Examples

Real GELLO

Real GELLO returns values

Terminology Support

CTS Access

GELLO needs vMR

“Virtual Medical Record” Simplified view of the RIM Not specified by GELLO standard

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

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
