Which HL7 standard specifies the structure and semantics of clinical documents for electronic exchange?

The Health Level Seven (HL7) standard that specifies the structure and semantics of clinical documents for electronic exchange is the Clinical Document Architecture (CDA). CDA provides a framework for the creation, exchange, and archiving of clinical documents and outlines how healthcare information is represented electronically.

This standard ensures that clinical documents, such as discharge summaries, progress notes, and other types of health records, can be shared and understood by various healthcare systems. CDA defines the data types, formats, and encoding standards needed to maintain the integrity of this information across different platforms and institutions.

The other options do not pertain specifically to the structure and semantics of clinical documents. CPOE (Computerized Physician Order Entry) focuses on the electronic ordering of medications and tests, ICD (International Classification of Diseases) relates to the classification of diseases and health conditions for statistical and billing purposes, while RFID (Radio-Frequency Identification) is a technology used for tracking and identifying objects via radio waves.
