HL7

Definition

HL7, or Health Level Seven, is a set of international standards for the exchange of electronic health information. It focuses on the interoperability between different healthcare systems, enabling the sharing of patient data across various applications and platforms. By establishing protocols for how data should be formatted and transmitted, HL7 plays a crucial role in clinical laboratory analyzers and data acquisition systems, ensuring that medical devices and software can effectively communicate with each other to support patient care.

5 Must Know Facts For Your Next Test

1. HL7 standards facilitate the exchange of various types of health information, including patient records, laboratory results, and billing information.
2. There are multiple versions of HL7, with HL7 V2.x being widely adopted for messaging in healthcare environments.
3. HL7 promotes the use of standardized vocabularies through its use of coding systems like LOINC and SNOMED CT to ensure consistent data interpretation.
4. The adoption of HL7 standards helps reduce errors associated with manual data entry by automating data transfers between systems.
5. HL7 also supports newer technologies such as Fast Healthcare Interoperability Resources (FHIR), which aims to simplify integration in healthcare applications.

Review Questions
