The following is their summary of the timeline for activities over the next several years.&nbsp; The Invitro Diagnostic Regulation (IVDR) is similar with a longer transition and shorter certificate validity ending on May 7, 2024 like the medical device timeline.&nbsp;<\/P><\/p>\n<p><P><span class=\"lia-inline-image-display-wrapper lia-image-align-center\" style=\"width: 640px;\"><img decoding=\"async\" src=\"http:\/\/blogs.sw.siemens.com\/wp-content\/uploads\/sites\/17\/2019\/09\/Image-Blog-1.jpg\" alt=\"Image Blog.jpg\" title=\"Image Blog.jpg\" \/><span class=\"lia-inline-image-caption\" onclick=\"event.preventDefault();\">Figure 1 &#8211; MDR Implementation Timeline \u2013 BSI Medical Device Roadshow<\/span><\/span><\/P><\/p>\n<p><P>We are currently about a year into the transition period, so we are well on our way to a significant regulatory hard stop.&nbsp; The regulation represents the largest update in international regulatory change in almost 25 years, so I thought it might be helpful to discuss some of the major changes, and how tools can be utilized to minimize the pain of transition.<\/P><\/p>\n<p><H1><SPAN style=\"font-size: 14.0pt; line-height: 107%;\">\u201c<U>Significant Changes<\/U>\u201d<\/SPAN><\/H1><br \/>\n<P>The MDR is essentially silent on the triggers for conducting a new clinical investigation when a device is changed or modified.&nbsp; The language specifies a requirement for clinical investigation when a \u201csignificant change\u201d is made.&nbsp; Likely factors would be related to Article 62 section 1.<\/P><\/p>\n<p><P><EM>Suitability of its intended use and achievement of the intended performance; to verify that the clinical benefits as specified have not been altered; that the device is clinically safe; the undesirable side effects continue to constitute acceptable risks when weighed against the benefits of the device.<\/EM><\/P><\/p>\n<p><P>This calls into question the extent to which a device that is qualified under the MDD standard during the 4 year certificate validity period would need to be re-qualified with MDR clinical requirements if \u201csignificant changes\u201d were made.&nbsp; In any case a detailed regulatory impact analysis should be completed for all of your devices to clearly understand the requirements for qualification under the MDR standard.&nbsp; At a minimum it would provide the plan required to quickly act on re-qualification as the need arises.&nbsp; Needless to say, this is an extremely detailed piece of work, and Siemens could help you to provide systems around the product design control, and regulatory impact analysis.<\/P><\/p>\n<p><H1><U><SPAN style=\"font-size: 14pt;

The first is \u201cany statistically significant increase.\u201d&nbsp; In isolation this is not new.&nbsp; However, when combined with \u201cincidents that are not serious incidents\u201d we find that statistical analysis is no longer limited to <EM>serious incidents<\/EM>.&nbsp; In the past we could focus on relatively few serious issues.&nbsp; Now we have a tipping point.&nbsp; The requirement is to do a statistical analysis on <EM>ALL<\/EM> of the incidents.&nbsp; For this serious consideration should be given to automated systems to provide exception management on the entire design stack.<\/P><\/p>\n<p><P>PMS Plan \u2013 Article 84 \u2013 Annex III Section 1.1<\/P><br \/>\n<UL><br \/>\n<LI>Information concerning the evaluation of serious incidents, including information from Periodic Safety Update Report (PSURs), and field safety corrective actions;<\/LI><br \/>\n<LI>Records referring to non-serious incidents and data on any undesirable side-effects;<\/LI><br \/>\n<LI>Information from trend reporting;<\/LI><br \/>\n<LI>Relevant specialist or technical literature, databases and\/or registers;<\/LI><br \/>\n<LI>Information, including feedbacks and complaints, provided by users, distributors and importers;

As you might imagine a regulatory change of this magnitude includes much more than I can cover in the context of a blog, but hopefully this provides you with a few of the weightier issues of concern to medical device manufacturer systems development work.&nbsp;
