HL7 Templates
Contents
Document Templates
- A template applied to the CDA schema to produce a desired level of information structure and content for a particular purpose – a particular type of document.
- Analogous to a paper form with mandatory and optional sections and described level of detail for each section.
- If sections can be coded, the specific coding scheme and any additional constraints are usually specified.
- May reference other templates applied to specific sections or entries.
Atomic Concept Definition Templates
- A template applied to part of a static model that specifies the structure and permitted coding to completely define a particular clinical concept.
- Any constraints on coded elements or value ranges are specified.
- Optional relevant components that may add nuances in particular circumstances are included.
- Atomic Concept Definition Templates are designed to be reusable in many different contexts.
- CEN defines Archetypes as atomic concept definitions formally approved by recognized clinical bodies.
- The stereotypical example is Blood Pressure, composed of 2 numerical measures with optional additional information about patient positioning, cuff size, etc.
Aggregate Measures Templates
- A template applied to an observation with multiple components that constrains the content and relationship of components.
- Constraints may be to optionality or to valid value ranges or coded value sets.
- Application of constraints may be conditional depending on values in other components.
- HL7 balloted static models have the information structures that can describe these component relationships, but to define a specific named set that can be referenced consistently would be a template.
Computed Measures Templates
- A template applied to an observation that has multiple components.
- The constraints apply to the content and relationships of the components, but also describes the computational algorithm that derives a computed measure from the component measures.
- An APGAR score is an example.
Assembly or sub-assembly Templates
- HL7 Templates applied to an “organizer” level of a static model that defines the content of components for a particular purpose.
- Constraints can be any structural or non structural variety and may reference other templates.
- In effect, the “Assembly” constraints are the sum total of all the constraints expressed in referenced templates plus any associated with the “Assembly” as a whole.
