ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. The procedures used to develop this document and those intended for its further

24、ISO/TR 12310:2015(E) Introduction This work item is a Technical Report that will identify and discuss principles and guidelines for the measurement of conformance in the implementation of terminological systems, in particular, as applied to Electronic Health Record (EHR) systems. This item will leve

25、rage the current work under way in Canada and will be developed in liaison with International Health Terminology Standards Development Organization (IHTSDO) and the Vocabulary Committee of HL7 in the spirit of harmonization across organizations with similar interests. Additional terminology organiza

26、tions, active projects and existing expertise will be sought out for input into this work item. Conformance is a key step in helping stakeholders determine if implementations of terminology systems have been done in a correct and consistent manner, particularly as implemented in EHRs. Loose declarat

27、ions regarding terminological systems that cannot be tested with meaningful results do very little to support the end goal of the interoperable EHR. Therefore, the principles and guidelines for establishing and measuring conformance will focus on identifying the degrees of conformance of terminologi

28、cal systems with or without use in messaging standards. This Technical Report is intended to define what is meant by conformance with respect to terminology systems, particularly as applied to EHR systems, and it is expected to facilitate the formulation of policies and governance practices locally

29、or nationally. This Technical Report is timely as the emerging IHTSDO and progressive implementation of the EHR will lead to the increasing awareness of conformance with respect to terminologies and consistent implementations that allow interoperability by all end-users. The focus of this Technical

30、Report is to define best practices and a framework for establishing and measuring conformance. The scope of this Technical Report will include the identification of definitions and best practice considerations for what constitutes conformance to terminology systems and the principles for which confo

31、rmance can be demonstrated.vi ISO 2015 All rights reserved Health informatics Principles and guidelines for the measurement of conformance in the implementation of terminological systems 1 Scope The purpose of this Technical Report is to define a framework of good practices for terminology system ma

32、intenance and the principles for which conformance can be demonstrated. The primary focus is the application of terminology system to Electronic Health Record (EHR) systems, although the principles and guidelines can be applied broadly in health informatics The scope of this Technical Report will in

33、clude, at a minimum, the following considerations for keeping terminology systems and associated reference material clinically and/or technically relevant and valid: governance models and practices; high level processes; requirements for managing the change. The scope of this Technical Report will n

34、ot include a definition of the detailed processes for performing terminology maintenance. This Technical Report aims to define the framework of good practices for EHRs and systems regarding terminology maintenance within these systems. This Technical Report relates directly to the ability of these r

35、ecords to be safe and legally accurate records of healthcare in the environment of changing technologies related to the use of clinical terminologies to represent meaning within these systems. 2 Objective This Technical Report identifies considerations for the expression and evaluation of conformanc

36、e for solutions that make use of terminology. The specific focus of this Technical Report is terminology used in healthcare solutions. However, the principles should apply to solutions implementing terminology across the health industry. “Solutions” is interpreted broadly and includes both software

37、and hardware technical implementations, as well as other specifications that are based on or claim to adhere to all or part of the specification against which conformance is being assessed. Implementation in this Technical Report does not consider procedural or governance requirements. By using the

38、definitions and recommendations found here-in, standards bodies, implementers, and other parties can better achieve their objectives in the development and use of specifications that make use of terminologies and can better express their terminology capabilities. This Technical Report is intended to

39、 be independent of any particular terminology or terminological approach, though some portions of the guidance provided will only apply to certain types of terminologies. 3 T erms a nd definiti ons For the purposes of this document, the following terms and definitions apply. NOTE Because “terminolog

40、y” is such a broad term, conformance actually needs to be stated in terms of the various terminology components that are referenced in a specification. These components will also be defined. TECHNICAL REPORT ISO/TR 12310:2015(E) ISO 2015 All rights reserved 1 ISO/TR 12310:2015(E) 3.1 conformance adh

41、erence of a system or specification to the expectations set by another specification Note 1 to entry: The general definition for conformance has changed over time and been refined for specific standards. In 1991, ISO/IEC 10641 defined conformance testing as “test to evaluate the adherence or non- ad

42、herence of a candidate implementation to a standard.” ISO/IEC/TR 13233 defined conformance and conformity as “fulfillment by a product, process or service of all relevant specified conformance requirements.” In recent years, the term conformity has gained international use and has generally replaced

43、 the term conformance in International Standards. Note 2 to entry: In 1996 ISO/IEC Guide 2 defined the following three major terms used in this field: conformity - fulfillment of a product, process, or service of specified requirements; conformity assessment - any activity concerned with determining

44、 directly or indirectly that relevant requirements are fulfilled; conformity testing - conformity evaluation by means of testing. 3.2 code system managed collection of concept representations (3.4) intended for use in persisting or sharing of information 3.3 concept single mental representation of s

45、ome real or abstract thing Note 1 to entry: Concepts should be unique within a code system (3.2). 3.4 concept representation mechanism by which the system can express a concept (3.3) Note 1 to entry: Different representations can serve different purposes. Most code systems (3.2) support multiple rep

46、resentations for each concept (3.3), sometimes even multiple representations of a given type. In some cases, distinct representations of a concept (3.3) may have their own identifier assigned within the code system (3.2) for maintenance and internal reference purposes. The types of representations a

47、re code (3.4.1), concept id (3.4.2), and concept designation (3.4.3). 3.4.1 code concept representation (3.4) intended for use when representing a concept (3.3) in a computable manner EXAMPLE Passing into a decision support tool or for use in data exchange. 3.4.2 concept id concept representation (3

48、.4) that is unique within the code system (3.2) and that is used internally by the code system (3.2) when referencing concepts (3.3) 3.4.3 concept designation human consumable representation of the concept (3.3) Note 1 to entry: A concept designation may or may not be a string of characters (could b

49、e multimedia); generally subject to language variants.2 ISO 2015 All rights reserved ISO/TR 12310:2015(E) 3.4.3.1 concept name concept designation (3.4.3) that is the unique designation of the concept (3.3) in the code system (3.2) and intended for human understanding Note 1 to entry: This is usually text but might also be graphical for some code systems (3.2). For example, images of different facial expressions for a code systems (3.2) representing pain scales. 3.5 code system partition result of dividing a code identifier namespace into
