Michael van der Zel

HIT-Architect

MDA Forms Based on DCMs @UMCGHL7 UK TC & RIMBAA Joint WGM London UK, 04-nov-2010

University Medical Center Groningen, Netherlands


Subject

In the Agenda: “Practical experiences of a Model Driven Architecture (MDA), based on DCMs (ISO Templates). The architecture is fully model driven, inclusive of the database model. Michael will also discuss the extensive role of terminology in this project.”


Actual Subjects

Form Section definition based on DCM and generation of HL7 v3

Form generation based on HL7 v3 Templates and CUI Clinical Noting in Forms Guidance

Clinical Data Repository to store instances


free text

CD observation with ValueSet of 4.

BL observations in section dizzyness


derived PQ observation


The Model Behind a Form

Form has Sections

Form has status

Section is possibly reusable

Section is possibly repeatable

Section has Sections

Section has Observations

Observation is of type X


Each Observation pattern will have a UI

BL will have a label and a Yes, No answer

PQ will have a label and a number input field with a unit behind it

CD with a valueset of <4 will have a label and list of items as radio buttons

CD with a valueset of >=4 and <32 will have a list

CD with a valueset of >1000 will have a Google Search

etc.

A_CareStatement (REPC_MT000100UV01)


Database

Actually a CDR CRUD ervice

Can store instances of CareStatement and check it against a Template

A Template is also an instance of CareStatement

Hybrid XML / RDBMS Database


CDR XML SQL Diagram

XML in column(e.g. SQL-Server 2005)

With XPathindex columns


Detailed Clinical Models

Back to the MDA

Leaf Form Sections (like Smoking) will be defined by Detailed Clinical Models

Mapping from DCM Information Model to HL7 v3 Care Statement

Actually I will define the form similar to DCM's


Payload

Detailed Clinical Model

Convert to Care StatementTemplate

DCM Information Model

Care Record Template (Logical)
