1、ANSI/AAMIBE83:2006/(R)2011Biological evaluation of medical devicesPart 18: Chemical characterization of materialsAmerican National StandardThe Objectives and Uses of AAMI Standards andRecommended PracticesIt is most important that the objectives and potential uses of an AAMIproduct standard or recom

2、mended practice are clearly understood.The objectives of AAMIs technical development program derivefrom AAMIs overall mission: the advancement of medicalinstrumentation. Essential to such advancement are (1) a continuedincrease in the safe and effective application of current technologiesto patient

3、care, and (2) the encouragement of new technologies. It isAAMIs view that standards and recommended practices cancontribute significantly to the advancement of medicalinstrumentation, provided that they are drafted with attention to theseobjectives and provided that arbitrary and restrictive uses ar

4、e avoided.A voluntary standard for a medical device recommends to themanufacturer the information that should be provided with or on theproduct, basic safety and performance criteria that should be con-sidered in qualifying the device for clinical use, and the measurementtechniques that can be used

5、to determine whether the device conformswith the safety and performance criteria and/or to compare the per-formance characteristics of different products. Some standards em-phasize the information that should be provided with the device,including performance characteristics, instructions for use, wa

6、rningsand precautions, and other data considered important in ensuring thesafe and effective use of the device in the clinical environment.Recommending the disclosure of performance characteristics oftennecessitates the development of specialized test methods to facilitateuniformity in reporting; re

7、aching consensus on these tests canrepresent a considerable part of committee work. When a draftingcommittee determines that clinical concerns warrant the establishmentof minimum safety and performance criteria, referee tests must beprovided and the reasons for establishing the criteria must bedocum

8、ented in the rationale.A recommended practice provides guidelines for the use, care,and/or processing of a medical device or system. A recommendedpractice does not address device performance per se, but ratherprocedures and practices that will help ensure that a device is usedsafely and effectively

9、and that its performance will be maintained.Although a device standard is primarily directed to the manufac-turer, it may also be of value to the potential purchaser or user of thedevice as a fume of reference for device evaluation. Similarly, eventhough a recommended practice is usually oriented to

10、wards healthcare professionals, it may be useful to the manufacturer in betterunderstanding the environment in which a medical device will beused. Also, some recommended practices, while not addressing deviceperformance criteria, provide guidelines to industrial personnel onsuch subjects as steriliz

11、ation processing, methods of collecting data toestablish safety and efficacy, human engineering, and otherprocessing or evaluation techniques; such guidelines may be useful tohealth care professionals in understanding industrial practices.In determining whether an AAMI standard or recommendedpractic

12、e is relevant to the specific needs of a potential user of thedocument, several important concepts must be recognized:All AAMI standards and recommended practices are voluntary(unless, of course, they are adopted by government regulatory orprocurement authorities). The application of a standard or r

13、ecom-mended practice is solely within the discretion and professionaljudgment of the user of the document.Each AAMI standard or recommended practice reflects thecollective expertise of a committee of health care professionals andindustrial representatives, whose work has been reviewed nationally(and

14、 sometimes internationally). As such, the consensusrecommendations embodied in a standard or recommended practiceare intended to respond to clinical needs and, ultimately, to helpensure patient safety. A standard or recommended practice is limited,however, in the sense that it responds generally to

15、perceived risks andconditions that may not always be relevant to specific situations. Astandard or recommended practice is an important reference inresponsible decision-making, but it should never replace responsibledecision-making.Despite periodic review and revision (at least once every fiveyears)

16、, a standard or recommended practice is necessarily a staticdocument applied to a dynamic technology. Therefore, a standardsuser must carefully review the reasons why the document wasinitially developed and the specific rationale for each of itsprovisions. This review will reveal whether the documen

17、t remainsrelevant to the specific needs of the user.Particular care should be taken in applying a product standard toexisting devices and equipment, and in applying a recommendedpractice to current procedures and practices. While observed orpotential risks with existing equipment typically form the

18、basis for thesafety and performance criteria defined in a standard, professionaljudgment must be used in applying these criteria to existing equip-ment. No single source of information will serve to identify aparticular product as “unsafe“. A voluntary standard can be used asone resource, but the ul

19、timate decision as to product safety andefficacy must take into account the specifics of its utilization and, ofcourse, cost-benefit considerations. Similarly, a recommendedpractice should be analyzed in the context of the specific needs andresources of the individual institution or firm. Again, the

20、 rationaleaccompanying each AAMI standard and recommended practice is anexcellent guide to the reasoning and data underlying its provision.In summary, a standard or recommended practice is truly usefulonly when it is used in conjunction with other sources of informationand policy guidance and in the

21、 context of professional experience andjudgment.INTERPRETATIONS OF AAMI STANDARDSAND RECOMMENDED PRACTICESRequests for interpretations of AAMI standards and recommendedpractices must be made in writing, to the Manager for TechnicalDevelopment. An official interpretation must be approved by letterbal

22、lot of the originating committee and subsequently reviewed andapproved by the AAMI Standards Board. The interpretation willbecome official and representation of the Association only uponexhaustion of any appeals and upon publication of notice of interpre-tation in the “Standards Monitor“ section of

The existence of an AAMI standard does

27、not in any respect preclude anyone, whether they have approved the standard or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standard. AAMI standards are subject to periodic review, and users are cautioned to obtain the latest editi

AAMI procedures require that action be taken to reaffirm, revise, or withdraw this standard no later than 5 years from the date of publication. Interested parties may obtain current information on all AAMI standards by

29、calling or writing AAMI. All AAMI standards, recommended practices, technical information reports, and other types of technical documents developed by AAMI are voluntary, and their application is solely within the discretion and professional judgment of the user of the document. Occasionally, volunt
