UB-92   -   Uniform Bill version 1992.

UCDHS   -   University of California at Davis Health System.   See CHeQ, IPHI

UDDI   -   Universal Description, Discovery, and Integration was a platform-independent, XML-based registry for businesses worldwide to list themselves on the Internet, and a mechanism to register and locate web service applications. Sponsored by OASIS and launched in 2000, the effort peaked after a few years. In 2012 Microsoft initiated removal of UDDI services from future versions of Windows Server.   See OASIS, SOAP, W3C, WSDL

UI   -   See User Interface

Ultrasound   -   In physics, the term "ultrasound" refers to all acoustic energy (longitudinal, mechanical wave) with a frequency above the audible range of human hearing. The audible range of sound is from 20 hertz to 20 kilohertz, therefore an ultrasound is a frequency greater than 20 kilohertz.   See Sonogram

UML   -   In software engineering, the Unified Modeling Language (UML) is a general-purpose modeling language that includes a graphical notation used to create an abstract model of a system, referred to as a UML model.   See Model

UMLS   -   The Unified Medical Language System, maintained by the U.S. National Library of Medicine, integrates and distributes key terminology, classification and coding standards, and associated resources to promote creation of more effective and interoperable biomedical information systems and services, including electronic health records.   See NIH, NLM, RxNORM

Unsecured PHI   -   Protected Health Information (PHI) that is not secured through the use of encryption or manual destruction.   See HIPAA, PHI

URL   -   The Uniform Resource Locator, created in 1994 by RFC 1738, established the initial syntax and semantics of formalized path names for location and access of resources via the Internet.   See IETF, RFC

Unit Test   -   A standard acceptance testing process by which the elements of a system are individually and comprehensively tested.   See Acceptance Testing

UPIN   -   Unique Provider Identification Number, a six character alphanumeric identifier assigned to all Medicare physician and non-physician providers.   See NPPES

USAF   -   United States Air Force.   See DoD, OODA

USB   -   Uniform Serial Bus.

Use Case   -   A use case is a narrative solution in software and systems engineering to capture the functional requirements of a system. The AHIC Use Cases, developed by ONC during the Bush Administration, sought to characterize the system requirements of the NHIN. The AHIC Use Cases ultimatelty failed to accelerate development of agile and adoptable health IT interoperability solutions due to an impenetrable complexity and marginal operational utility. The NHIN Direct User Stories are a lighter weight successor that may sought to be relevant via functional constraints which limit the complexity of each "story" to simple responsibility for point to point transport.   See AHIC, HITSP, NHIN, NHIN Direct, ONC

User Interface   -   The method by which a user interacts with a machine, such as operating a computer by using a keyboard along with a mouse pointing device to interact with the machine.   See GUI
