y The most important concept to keep in

mind when discussing the definition and

use of data standards is predictability.

y Predictability-associated with information exchange

allows application developers to design

and implement application architecturesthat can exploit expectations to allow for

more efficient processing.

y Improve communications

y Reducing amount of manual interventionand facilitating for straight-through

processing that increases productivity and

costs.

y Establishing a repository of definitions of

common health care terms and

procedures.

y Providing a means for publishing those

definitions for the benefit of information

exchange partners.

y Improving the quality and consistency of

health care

y Improved patient safety

Data standards can provide a

blueprint for new or modernized

application development.

y data standards contribute to a baseline

for determining the difference betweenvalid and invalid exchanges and,

consequently, measuring some aspects of

information compliance.

y Helps in defining metrics that can

contribute to an overall information

quality scorecard.

PROCESSPROCESSPrinciplesy Consensus The views of all interests are

taken into account: manufacturers, vendors

and users, consumer groups, testinglaboratories, governments, engineeringprofessions and research organizations.

y Industry wide Global solutions to satisfyindustries and customers worldwide.

y Voluntary International standardization ismarket driven and therefore based onvoluntary involvement of all interests in themarket-place.

Three main phases:Three main phases:

y The need for a standard is usually expressedby an industry sector, which communicatesthis need to a national member body. The

latter proposes the new work item to ISOas a whole. Once the need for anInternational Standard has been recognizedand formally agreed, the first phaseinvolves definition of the technical

scope of the future standard. This phaseis usually carried out in working groupswhich comprise technical experts fromcountries interested in the subject matter.

y Once agreement has been reached on

which technical aspects are to be covered

in the standard, a second phase is entered

during which countries negotiate the

detailed specifications within the

standard.This is the consensus-

building phase.


9/10

y The final phase comprises the formalapproval of the resulting draftInternational Standard (the acceptance

criteria stipulate approval by two-thirds ofthe ISO members that have participatedactively in the standards developmentprocess, and approval by 75% of allmembers that vote), following which theagreed text is published as an ISOInternational Standard.


10/10

Most standards require periodic revision.

Factors are:

y technological evolution

y new methods and materials

y new quality and safety requirements.
