Laboratory Panels &Tests Discussions
(a.k.a. Observation Groups verses Atomic Observations)

Option 6 – Compound & Indivis. Statements
• Specialise Entry into 2 new reference model classes:– Compound Entry
• Used for panels, and may contain data elements, compound statements or atomic statements; Contains shared context.
– Indivisible Entry• Used for individual tests, and represent indivisible unit of
information about the patient; All context is self-contained or derivable.
• Pros– Consistent query paths– Identifies indivisible units of information– Allows arbitrary levels of nesting– Allows context derivation rules to be applied
• Cons / Implications– Requires reference model to be changed– Requires the implementation to ensure atomic statements are
complete, and independently queryable

Panel Interpretation: …ELEMENT:
I think this example mixes in elements of the physical model and the logical model. I don’t think there is a need to create logical models like this.

The Reference Model should allow both of the next two styles of modeling

Modeling Guideline
• If the contextual element applies to everything in the panel, place the element at the panel level
• If the contextual element applies to only some items in the panel, place the contextual element in each member of the panel to which it applies
