1 HL7 Working Group Session May 3-7, 2004 San Antonio, TX Standards for Implantable Devices - Cardiac

2 Overview Project Progress Next Steps Artifact Review Appendix: –Implantable Cardiac Device Overview –Current Clinician Environment –Implantable Device – Cardiac (IDC) Project Overview –Participants

3 Project Progress Validated requirements through interviews and site visits Compiled HL7 v3.0 artifacts for Device Summary message –Storyboard –Application Roles –Trigger Event –Message Type –Interaction Diagram –Refined Message Information Model (R-MIM) –Hierarchical Message Definition (HMD) Identified nomenclature terms to be balloted via IEEE Vital Signs Nomenclature

4 Next Steps Obtain feedback from participants and enhance current artifacts Prepare Device Summary artifacts for ballot Participate in enhancements to IEEE Vital Signs Nomenclature Gather additional requirements through interviews and site visits Create new HL7 v3.0 artifacts to support additional messages in this area

5 Scenario Overview: Office Follow-Up

6 Device Summary Data Aggregated set of data that is typically filed in the patient’s chart at follow-up Implanted Device Data Types: –Device Therapy Settings Pacing settings Defibrillation settings –Arrhythmia Logging Data Event Counters –Diagnostic Data Diagnostics on device functionality (e.g., lead impedance, sensing thresholds, pacing thresholds)
