  13. CDA Templates • What is a Template? • How can it be expressed? • What can I do with it?

  14. What is a Template? A template is an expression of a set of constraints on the RIM that is used to apply additional constraints to a portion of an instance of data which is expressed in terms of some other Static Model. HL7 Specification and Use of Reusable Constraint Templates

  15. Expression of Templates • Formal Written Definition • In human readable form • Explicit or Implicit HL7 Static Model • Application results in a Static Model • Implementation Specific Representations • Static Model • W3C Schema • ISO Schematron

  16. Features of a Template • Has an Identity • Can Require, Prohibit, or Suggest (constrain) • RIM Attributes • Relationships • Other Templates • Specify Cardinality • Conditional and Co-relationships • Can Inherit from other Templates

  17. IHE Patient Care Coordination Templates • Are Content Profiles or Modules • Have a formal Written Definition • Result in an Implicit HL7 Static Model • Use ISO Schematron for Implementation • Inherit from ASTM/HL7 CCD when possible • Provide Constraints on • Documents • Sections • Entries

  18. Document Level Templates • Template ID • Summary Description • Format Code for use with XDS • Standards Used • Data Element Table (needs Definitions) • Specification • Sections • (Header) Entries • Conformance • Sample XML (abbreviated) • Schematron

  19. Document Template Specification

  20. IHE PCC Document Templates (12) • Medical Documents Specification • Medical Summary Specification • Referral Summary Specification • Discharge Summary Specification • PHR Extract Specification • PHR Update Specification • Emergency Department Referral Specification • Antepartum Summary • Triage Note • Nursing Note • Composite Triage and Nursing Note • ED Physician Note

  21. Section Level Template • Template ID • Parent Template(s) • Summary Description • LOINC Code • Required and Optional Sub-sections • Required and Optional Entry Templates • Sample XML (abbreviated) • Schematron
