<unk>  is used in a number of different ways, some of which are: * It captures clinical information at the level of detail needed for the provision of healthcare * Through sharing data it can reduce the need to repeat health history at each new encounter with a healthcare professional * Information can be recorded by different people in different locations and combined into simple information views within the patient record * Use of a common terminology decreases the potential for differing interpretation of information * Electronic recording in a common way reduces errors and can help to ensure completeness in recording all relevant data * Standardised information makes analysis easier, supporting quality, cost effective practice, research and future clinical guideline development * A clinical terminology allows a health care provider to identify patients based on specified coded information, and more effectively manage screening, treatment and follow up Use cases More specifically, the following sample computer applications use<unk> : *Electronic Health Record Systems *Computerized Provider Order Entry CPOE such as E-Prescribing or Laboratory Order Entry *Catalogues of clinical services; e.g., for Diagnostic Imaging procedures *Knowledge databases used in clinical decision support systems (CDSS) *Remote Intensive Care Unit Monitoring *Laboratory Reporting *Emergency Room Charting *Cancer Reporting *Genetic Databases Access<unk>  is maintained and distributed by<unk>  International, an international non-profit standards development organization, located in London, UK.. The use of<unk>  in production systems requires a license. There are two types of license: # Country/territory membership in<unk>  International (charged according to gross national product). # Affiliate license (dependent on the number of end users). LDCs (least developed countries) can use<unk>  without charges. For scientific research in medical informatics, for demonstrations or evaluation purposes<unk>  sources can be freely downloaded and used. The original<unk>  sources in tabular form are accessible by registered users of the Unified Medical Language System (UMLS) who have signed an agreement. Numerous online and offline browsers are available. Those wishing to obtain a license for its use and to download<unk>  should contact their National Release Centre, links to which are provided on the IHTSDO website. License free subsets To facilitate adoption of<unk>  and use of<unk>  in other standards, there are license free subsets. For example, a set of 7 314 codes and descriptions is free for use by users of DICOM-compliant software (without restriction to IHTSDO member countries). Global Patient Set (GPS) subset GPS was released in Sep 2019 and contains 21 782 concepts.
