QDA – Business case

· Summaries are made by aggregating information from often different sources

· Need for a profile that can take care of complex multi-query creation

QDA – Use Cases

· Medication Summary

· Prescriptions

· Dispensations

· Allergies interactions contra-indications

· Relevant lab values

· Relevant diagnoses

· Patient Summary

· From multiple sources; ‘Blue button’

· Emergency Care Summary

· Combined information from emergency call center, ambulance, Emergency department, ICU

· Integrated Care Overview

· Combined information from PCP, dietician, physiotherapist, laboratory

QDA – Query Dispatch and Aggregate

· Generic tool for the creation of multi-source summaries and aggregated reports

· One report request, multiple subqueries, one report result

· Can collect information from database queries, existing documents, and other methods

Purposes

· Can be called by ODD (On Demand Document) to create documents from multiple sources (including non-IHE) to create on-the fly actual information

· Can be used by any Actor that needs a summary (view) from multiple existing documents

Aggregate

Remarks· Some parts of the functionality can be covered by existing profiles. However, some functionality is

missing:

· Transforming documents / messages / webservices from different sources into one document

· Receiving one report request, and then sendif a number of preformatted subqueries

· Configurable subqueries

· Add RECON / MCV / DEN / DSG etcetera to format and create the result-document

· Content Creator

Remarks

Profile or Whitepaper?o   A lot of IHE profiles start as whitepapero   If there are “holes” in existing profiles, it would definitely warrant a profileo   IHE/ITI: pure configuration management profiles often don’t make it through the first selectiono   Find synergy with DAF (recipe for existing problems) / RECON (aggregation) ? XCF is not the wholeanswer:o   Is an optimization of XCA Query and Retrieveo   It does not aggregate results into one documento   Is not plug and play with ODD: there is no way to snapshot the resultsBut it can be used as one of the ‘fetch’ options ·  Presentationo   You might want to make the diagram/text more clear that you want to further profile/describe/specify the currently opaque ODD Document Source. This is probably not clear to people right now. QDA Content Source seems to be a separate actor interacting with a ODD Document Source. Maybe create a new diagram with just the new actors/transactions.

Behavioral pattern

Remarks

o   How can a profile like qed / XCF know which subqueries it needs to perform to aggregate the summary?
