11、2004 All rights reserved Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested i
12、n a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commis
13、sion (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical
14、 committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. In other circumstances, particularly when there is an urgent market requirement for such documents, a technical committee may d
15、ecide to publish other types of normative document: an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical experts in an ISO working group and is accepted for publication if it is approved by more than 50 % of the members of the parent committee casting a vote; a
16、n ISO Technical Specification (ISO/TS) represents an agreement between the members of a technical committee and is accepted for publication if it is approved by 2/3 of the members of the committee casting a vote. An ISO/PAS or ISO/TS is reviewed after three years in order to decide whether it will b
17、e confirmed for a further three years, revised to become an International Standard, or withdrawn. If the ISO/PAS or ISO/TS is confirmed, it is reviewed again after a further three years, at which time it must either be transformed into an International Standard or be withdrawn.

20、countries and their sub-divisions exist in many forms and for many uses. From statistical aggregation to telecommunications use, from internet top-level domains to member country lists, and from healthcare information to athletic records, there is a need for the consistent, comparable, and codified
21、identification of countries. These mechanisms are “standard” in the sense that a formal list of names and codes is kept and used by multiple individuals or groups, and processes are in place for maintenance of these lists. This Technical Specification provides a description, review, and recommendati
22、on, all within a healthcare information context, of two internationally recognized standards that are in use today for country identifiers and their subdivisions. Annexes A, B, C, D and E of this Technical Specification are for information only. These annexes provide an overview of various country i
23、dentifier standards used internationally, and provide guidance around the use of such standards for purposes of developing other health informatics standards. A review of various international organizations and their application or use of country identifier codes has also been included. Copyright In

ISO 3166-2 shall be the primary reference standard for use in health care to identify subdivisions of a country where systems, applications or data formats require such subdivision identifiers. Where relevan

34、Rationale The rationale for the standards identified in 3.1.1 and 3.1.2 as country identifier reference standards is as follows: these two standards together provide both the full jurisdictional and geographic capability for country identification; these standards enable country identification for p
35、erson based and service based health care use; these two standards complement one another for purposes of location identification and contact identification and for jurisdictional and geographical identification; these standards allow for flexibility in use and implementation through the availabilit
36、y of alpha-2, alpha-3 and numeric-3 codes and enables stability and neutrality through the availability of the numeric-3 coding; geographical aggregation of health data from multiple countries can be accommodated outside the above standards, without affecting these standards or their use; these stan
37、dards have in place politically neutral maintenance agencies; a process for updates between editions of the primary reference standard ISO 3166 (all parts) is in place through web based formal newsletters issued by the maintenance agency. 3.3 Liaison Ongoing liaison between ISO/TC 215 and the ISO 31
38、66 Maintenance Agency (ISO 3166/MA) with respect to the use of ISO 17120 and ISO 3166 (all parts) in health care as technical reference standards shall continue, in order to: improve communications for the health care sectors within all countries respecting the use and maintenance of this Technical
39、Specification; address with ISO 3166/MA issues of code reassignment, user assigned code registration and timely revisions.

40、1 MDTNo reproduction or networking permitted without license from IHS -,-,- ISO/TS 17120:2004(E) ISO 2004 All rights reserved 3 Annex A (informative) Technical introduction A.1 Overview Countries are both political and geographical entities. Reference to countries may be for their jurisdictional rel
41、evance (political, administrative) or their physical location (geographical). The context of use of a country identifier standard is useful in determining the applicability, adoption, or agreement for a standard. Whether that use is for identification, contact or analysis purposes, different country
42、 identifier standards may be applicable. Two methods are being undertaken to address the context for a country identifier mechanism in health care. The first, scenarios or “story boards”, provide the overall context and need for this standard and relate the country identifier work to real and unders
43、tandable healthcare situations. The second, use cases, provide very specific tests and a formal validation capability for a standard. The following short use case and scenario supports the use of this Technical Specification in health informatics standards development. It is as important to understa
44、nd what is excluded in this Technical Specification as it is to know what is included. This Standard is not relevant in health care for very specific patient locations or in any way for patient identifiers. It is not meant to serve as an exact geographical locator such as given in a geographical pos
45、itioning system. While acknowledging that country boundaries are inherently geographic, it is clear that this country identifier technical reference standard does not apply to the location or identity of any specific patient, beyond the identification of the country or sub-division of that patient.
46、A.2 An elderly man becomes ill while on vacation A.2.1 Scenario Mr. Jones was a resident of Australia and was on vacation in Canada. Mr. Jones became extremely ill with a communicable disease and collapsed from exhaustion. He was taken by ambulance to the emergency department of a public hospital in
47、 Toronto. After being assessed by the emergency room physician, Mr. Jones was hospitalized. As a hospital inpatient, Mr. Jones continued to receive health services until his health improved and he could be discharged. These events trigger a number of activities that require information about “countr
48、ies”. First, Mr. Jones country of residence is of interest to the hospital administration because it will need to determine how the health service will be paid. Because Mr. Jones is a non-resident of Canada, the services he receives are not eligible for payment under Canadas national health program. The hospital therefore needs to know the country location of Mr. Jones insurer, either public or private, so that a reciprocal billing arrangement can be initiated. Sec
