Category Specification Organisation Health Level Seven (HL7) Type Standard Version 1 Access Open Status Active Created Dec-20 Although there are several standards for expressing clinical quality logic, the standards are not widely adopted and present various barriers to point-to-point sharing of clinical knowledge artefacts. This specification enables shared understanding of clinical knowledge by defining a syntax-independent, canonical representation of logic that can be used to express the knowledge in any given artefact, and enables point-to-point sharing by defining a serialisation for that representation. It introduces a high-level, domain-specific language – Clinical Quality Language – focused on clinical quality and targeted at authors of measure and decision support artefacts.Main sections:· Author’s guide· Developer’s guide· Logical specification· Language semantics· Translation semantics· Physical representation· Appendix A: CQL syntax formal specification· Appendix B: CQL reference· Appendix C: Reference implementations· Appendix D: References· Appendix E: Acronyms· Appendix F: Glossary· Appendix G: Conventions· Appendix H: Timing interval calculation examples· Appendix I: FHIRPath function translation· Appendix J: List of tables· Appendix K: List of figures· Appendix L: CQL syntax diagrams Access HL7 Cross-Paradigm Specification: Clinical Quality Language, Release 1 By accessing this content, you are leaving this website.
