<p><b>New page</b></p><div>== Health Level 7: Clinical Quality Language ==<br />
<br />
'''Health Level 7 (HL7)''' is a set of international standards for the exchange, integration, sharing, and retrieval of electronic health information. One of the key components of HL7 is the '''Clinical Quality Language (CQL)''', which is a domain-specific language designed to express logic that is human-readable yet structured enough to be processed by computers.<br />
<br />
=== Overview ===<br />
CQL is used to define clinical quality measures and decision support rules. It provides a way to express the criteria for quality measures and clinical decision support in a way that is both understandable to clinicians and executable by health information technology systems. CQL is part of the HL7 Fast Healthcare Interoperability Resources ([[FHIR]]) standard, which aims to facilitate the exchange of healthcare information electronically.<br />
<br />
=== Features ===<br />
* **Human-Readable Syntax**: CQL is designed to be readable by clinicians, making it easier for them to understand and validate the logic.<br />
* **Interoperability**: CQL supports interoperability by providing a standard way to express clinical logic that can be shared across different health IT systems.<br />
* **Reusability**: The logic defined in CQL can be reused across different measures and decision support rules, reducing redundancy and improving consistency.<br />
<br />
=== Applications ===<br />
CQL is used in various applications within the healthcare industry, including:<br />
* **Clinical Decision Support (CDS)**: CQL can be used to define rules that provide clinicians with patient-specific assessments or recommendations to aid clinical decision-making.<br />
* **Quality Measurement**: CQL is used to define the criteria for clinical quality measures, which are used to assess the performance of healthcare providers.<br />
<br />
=== Related Standards ===<br />
CQL is part of a broader ecosystem of standards and specifications developed by HL7, including:<br />
* [[FHIR]]<br />
* [[HL7 Version 2]]<br />
* [[HL7 Version 3]]<br />
* [[Clinical Document Architecture (CDA)]]<br />
