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

Michael van der Zel 2010-nov-04 9

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.

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

Michael van der Zel 2010-nov-04 16
