  2. 9/19/2007 HL7 Atlanta – CDS TC 2 Discussion Topics • GELLO Status • GELLO BNF • GELLO Authoring Tool • Next Steps

  3. 9/19/2007 HL7 Atlanta – CDS TC 3 GELLO Status 2005GELLO passed as an HL7 & ANSI standard. 2006Industry outreach demonstrating the use of GELLO in ePrescribing Prior Authorization. Medical Objects, AU, GELLO Tool release. 2007GELLO web discussion group established by Margarita Sordo, Harvard/Partners. InferMed continued industry outreach to: • Demonstrate use of GELLO in a Clinical Trial Roadmap. • Identify pilot opportunities. InferMed release of GELLO Authoring Tool.

  4. 9/19/2007 HL7 Atlanta – CDS TC 4 GELLO BNF Feedback

  5. 9/19/2007 HL7 Atlanta – CDS TC 5 GELLO BNF Feedback

  6. 9/19/2007 HL7 Atlanta – CDS TC 6 GELLO BNF InferMed BNF Summary Comments: • GELLO BNF, posted to http://www.hl7.org/v3ballot/html/infrastructure/gello/gello.htm#BNF, contains many ambiguities, making it impossible to implement with standard compiler tools. • Syntax is difficult to read with anything more complex than one or two nested levels of if…then…else statements. • GELLO provides too many ways to describe the same semantic concept, making it difficult for a novice to determine how to develop expressions.

  7. 9/19/2007 HL7 Atlanta – CDS TC 7 GELLO Syntax Potential Next Steps: • Schedule periodic teleconferences to set a more definitive course for GELLO via HL7 DSS Listserv. • Document teleconference recommendations in preparation for re-balloting GELLO. • Test draft recommendations in at least 2 “real life” pilot applications before re-balloting.

  8. 9/19/2007 HL7 Atlanta – CDS TC 8 GELLO Authoring Tool New GELLO Authoring Tool, developed by InferMed UK, will be donated for industry use. • Preview: HL7 Atlanta – 9/07 • Capable of defining, encoding, and exporting structured GELLO Query Expressions. • Aligned to HL7 V.3 RIM class model.

  9. 9/19/2007 HL7 Atlanta – CDS TC 9 GELLO Authoring Tool • Tool Features & Functions: • Buttons for each key word, data type, pre-defined value, and operator. • Help text associated with each button. • Drop-down lists of classifiers from HL7 RIM, associated with IntelliSense. • Ability to import and save GELLO expressions. • Color coding of key words. • Syntax checking during authoring process and when expressions are saved.
