Templates & Implementation Guides Implementation Guides: here today Templates: here tomorrow Implementation Guides Clinical domain knowledge Ready-to-implement Validation rule set Templates “Re-usable bits” Abstract formalism Formalism relates IG to Reference Information Model Validation rule set derived from model Benefit of templates Automate rule set creation Relate implementations back to single model in such a way that can understand relationship between “reusable bits” at any level

Validating CDA document types .xPath, .xsl, Schematron prose √ .xsd CRS .xml Validates against generic schema <Section code=Plan> √ XPath validation of Implementation Guide requirements

Templates and IGs: ? Care Structures ? prose Implementation Guide CRS

Templates & IG validation: future prose IG: by hand CRS .xPath, .xsl, Schematron √ .xsd .xml Validates against generic schema <Section code=Plan> Template: automated rule derivation √ XPath validation of Implementation Guide requirements templates

Conclusions: concept Concept: viable Can extend to RIM-compliant expression of full domain with specialization Reference Information Model CDA + MRM RMIM Patient Care Med Rec CRS Care Structures CRS ambulatory CRS amb. pediatric CRS amb. geriatric CRS amb. pediatric local
