It is a concept and category within health informatics that describes systems and organizations that enable electronic transfer and sharing of clinical and administrative health data between separate entities. ## Key Facts - HIE is defined as the mobilization of health care information electronically across organizations (Wikidata description). - HIE is a subclass of health informatics, the discipline at the intersection of information science, computer science, and health care. - HIE is also associated with the class Regional Health Information Organization (RHIO), identified as a United States–country class. - Common aliases include "HIE" and the Chinese name "健康資訊交換系統". - UMLS Concept Unique Identifier (CUI): C3849995. - MeSH descriptor ID: D066275 (label: Health Information Exchange). - MeSH tree codes include E05.318.308.940.968.625.500.500 (qualifier: electronic health records), L01.313.500.500 (qualifier: health informatics), and L01.399.500.500 (qualifier: Health Information Management). - Freebase ID: /m/09gggr. - Techopedia ID: 15339. - Microsoft Academic (discontinued) ID: 2778759051. - Wikipedia title: "Health information exchange" with sitelink_count: 3 and available languages: Arabic (ar), English (en), Persian/Farsi (fa). ## FAQs ### Q: What is health information exchange (HIE)? A: Health information exchange is the electronic mobilization of health care information across organizations. It describes systems, processes, and organizational arrangements that enable health data to be transferred between separate entities. ### Q: How is HIE classified within academic disciplines? A: HIE is classified as a subclass of health informatics, the interdisciplinary field combining information science, computer science, and health care. It is also linked to the Regional Health Information Organization (RHIO) class in the United States. ### Q: What standard identifiers and subject headings exist for HIE? A: HIE has a UMLS CUI of C3849995, a MeSH descriptor ID of D066275, a Freebase ID of /m/09gggr, and a Techopedia ID of 15339. Microsoft Academic listed it under ID 2778759051 (discontinued). ### Q: Are there real-world HIE organizations referenced? A: Yes. Examples in the provided data include HealthShare Exchange of Southeastern PA (headquartered in Philadelphia, United States) and Chesapeake Regional Information System for our Patients (a Maryland HIE founded in 2009, headquartered in Baltimore, United States). ## Why It Matters Health information exchange defines the electronic movement of health data between organizations, forming a core capability within health informatics. As a category, HIE structures how separate healthcare entities can share clinical and administrative information electronically rather than relying solely on internal systems or paper records. This category is instantiated by organizational forms such as Regional Health Information Organizations and concrete exchanges (for example, HealthShare Exchange of Southeastern PA and Chesapeake Regional Information System for our Patients). Standardized identifiers and subject headings (UMLS CUI C3849995, MeSH D066275, Freebase /m/09gggr) support consistent indexing and discovery across biomedical and informatics resources. Because HIE sits at the intersection of information science, computer science, and healthcare, it is a distinct, referenced concept for research, policy, system design, and classification in medical subject heading taxonomies. ## Notable For - Explicitly defined in biomedical and informatics vocabularies: UMLS CUI C3849995 and MeSH descriptor D066275. - Classified as a subclass of health informatics and associated with the Regional Health Information Organization class in the United States. - Multiple authoritative identifiers: Freebase /m/09gggr, Techopedia ID 15339, and a (discontinued) Microsoft Academic ID 2778759051. - Documented real-world instances and regional exchanges, including HealthShare Exchange of Southeastern PA (Philadelphia) and Chesapeake Regional Information System for our Patients (inception 2009; Baltimore). - Multilingual Wikipedia coverage (Arabic, English, Persian/Farsi) under the title "Health information exchange." ## Body ### Definition - Term: Health information exchange (HIE). - Core description: Mobilization of health care information electronically across organizations. - Wikipedia title: "Health information exchange." ### Classification and Parent Fields - Subclass of: health informatics. - Related class: Regional Health Information Organization (RHIO) — noted as a class in the United States. ### Identifiers and Database Entries - UMLS CUI: C3849995. - MeSH descriptor ID: D066275 (listed as Health Information Exchange). - Freebase ID: /m/09gggr. - Techopedia ID: 15339. - Microsoft Academic ID (discontinued): 2778759051. ### MeSH Tree and Subject Headings - MeSH tree code E05.318.308.940.968.625.500.500 with qualifier "electronic health records". - MeSH tree code L01.313.500.500 with qualifier "health informatics". - MeSH tree code L01.399.500.500 with qualifier "Health Information Management". - MeSH label association: "Health Information Exchange" linked to D066275. ### Aliases and Language Coverage - Aliases: HIE; 健康資訊交換系統. - Wikipedia language availability: Arabic (ar), English (en), Persian/Farsi (fa). - Sitelink count (Wikipedia/applications): 3. ### Related Organizations (examples provided) - HealthShare Exchange of Southeastern PA — country: United States; headquarters: Philadelphia. - Chesapeake Regional Information System for our Patients — described as a health information exchange in Maryland, United States; inception: 2009; headquarters: Baltimore. ### Metadata and Usage Notes - Wikidata description succinctly states the core purpose: mobilization of health care information electronically across organizations. - The entity is positioned within informatics vocabularies and subject heading systems for biomedical indexing and interoperability work. ## References 1.
