Metric entropy – basic relation

1. Metric entropy – basic relation This diagram shows a 3-dimensional relation among {Use Case X Metric object class specialization X Obs format TYPE}. QoM motivations for selection of Metric class or Obs reporting format: (1.) Normalization of one of vector parameter values, e.g. Bpmean; (2.) Keeping BPvector values together w.r.t. each Tn; (3.) templating “mandatory” [subset] of variables needed for CDS alg (e.g. Vent Weaning [see HITSP TN905]). UseCase: Metric object class specialization entropy level See next slide for DIM::CDA transform architecture Obs format TYPE GASx73-CDA 3/26/12 jw1

2. Metric transform – x73 DIM  [HL7 RMIM  GAS] CDA This diagram shows a mapping of one of the 3 BP object instances through a virtual RMIM to GASx73 CDA XML. See following slide for relation to overall CDA XML. UseCase Metric object class specialization entropy level Obs format TYPE: GAS CDA [.xml] GASx73-CDA 3/26/12 jw1

3. Metric transform – x73 DIM  [HL7 RMIM  GAS] CDA This diagram shows a transform of 3 Obs samples from 3 x73 DIM BP objects {Sys/Dias/Mean} to HL7 GASx73 CDA XML format with a single Obs trend (Systolic) shown at right. UseCase: Obs format TYPE: GAS CDA [.xml] Metric object class specialization entropy level XML or single BP object Obs Trend (e.g. Systolic) GASx73-CDA 3/26/12 jw1

4. Metric entropy - scalability range This diagram shows wave-intensive info struct entropy scaling, ranging from single-Dev modality up through multi-Pt, multi-Modal; see HL7/x73 “gRIM”. GASx73-CDA 3/26/12 jw1
