phone on mute• Do not put your phone on hold – if you need to
take a call, hang up and dial in again when finished with your other call– Hold = Elevator Music = very frustrated speakers and
participants
• This meeting, like all of our meeting is being recorded– Another reason to keep your phone on mute when not
speaking
• Feel free to use the “Chat” feature for questions, comments or any items you would like the moderator or participants to know.

Query for Existing DataValue Proposition
• Exchange of information between Data Repositories and Clinical Data Consumers for:– Drug Safety– Public Health, Biosurveillance and Disease Registries– Identifying Qualifying Patients
• Clinical Trials• Disease Management
– Quality Reporting– Claims Submission– Decision Support Systems
• Using a single standard for query • Compatible with CCD
vs.• 30-60 HL7 V2.X Interfaces @ $10-20K/Inteface
HITSP TP21, QualityHITSP TP21, Quality
Scope• Problems and Allergies
– Disease Registries, EHR Systems, CDS• Vital Signs
– Monitoring Systems, EHR Systems, CDS• Diagnostic Results
– Laboratory and Radiology Information Systems, EHR Systems, CDS
• Medications– Pharmacy, EHR Systems, CDS
• Immunizations– Immunization Registries, EHR Systems, CDS
• Professional Services– Practice Management, Scheduling Systems, Care
Management, CDS
Key Technical Properties
• Support for Web Services and SOA Architecture• Use of one standard for all queries• Reuse of PCC Technical Framework Templates• Compatibility with ASTM/HL7 CCD

Data Elements (1)Common Observations •Simple measurements or reported values that can be determined using simple measuring devices (e.g., Height, Weight), or which can be reported by the patient (e.g., date of last menstrual period).
Diagnostic Results •Observations made or performed using laboratory testing equipment, imaging procedures, vision examinations, et cetera.
Problems and Allergies•These are a collection of diagnoses, clinical findings, allergies, or other risk factors that are recorded for the patient. The information may be obtained from patient reports, or through clinical decision making.
– Conditions: Disease conditions for the patient. – Intolerances: Allergies and other intolerances. – Risk Factors: Significant risk factors based on family history, social history, occupational exposures, et
cetera.
Medications •Medications that a patient is or has been taking for treatment of one or more conditions.
Immunizations •Immunizations that have been given, or which are planned to be given to the patient.
