This four-part series, using a fresh perspective, takes a bottom-up approach to PMS and starts by elaborating on the state of the art on the <\/em><a href=\"https:\/\/www.meddeviceonline.com\/doc\/risk-based-postmarket-surveillance-in-the-age-of-eu-mdr-incident-investigation-0001\">incident investigations in Part 1<\/a><em>. \u201cInvestigations\u201d are the basic iota of the PMS system upon which all further analysis, synthesis, and decision-making is based. With clarity on this most fundamental unit of PMS, a systems approach to both EU MDR and PMS are explored in <\/em><strong>Part 2<\/strong><em>. Successful implementation of an effective EU MDR-compliant PMS requires a systems approach which requires appreciation of not only the organizational context within which PMS operates but also the knowledge management as it relates to PMS generated data, information, knowledge, and wisdom. Part 3 will focus on the bedrock of EU MDR: the risk management system. It not only explores the interfaces between risk management and PMS but also discusses the postmarket aspects of risk surveillance and their accomplishments. Part 4 will detail an important upcoming topic with relevance going beyond EU MDR. Risk-based incident trending for postmarket signal detection is quickly becoming an expectation from most regulatory agencies and EU MDR is one of the first regulations to expressly document this requirement. The regulation asks for a methodology to gauge \u201cstatistically significant increases\u201d in a certain subset of postmarket incidents. This article details salient features of any such method such that any chosen tool can act as a postmarket risk monitor and, if used right, can also convert the lagging indicator of complaints and incidents into a leading key risk indicator. Key risk indicators can help establish preemptive preventive actions before benefit-risk profile can be adversely impacted.<\/em><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In Part 2 of this series, let\u2019s take a macro view of PMS. Why is EU MDR different and, for some companies, difficult? A reason is that it is asking us for a systems approach, not linear processes. It\u2019s asking us to not only define processes but also to define systems interfaces. It\u2019s asking us to transfer information and analysis across systems to ensure the most accurate picture of device risk and benefit can be obtained.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Do not mistake process for a system. A system is qualitatively different than a process. Systems are made up of components that may or may not have direct input\u2013output links among them. W.E. Deming, the American engineer, statistician, professor, and author, defined a system as a network of interdependent components that work together to try to accomplish the aim of the system.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"803\" height=\"645\" src=\"https:\/\/www.medsyscon.com\/wp-content\/uploads\/2020\/12\/pic1.jpg\" alt=\"\" class=\"wp-image-1990\" srcset=\"https:\/\/www.medsyscon.com\/wp-content\/uploads\/2020\/12\/pic1.jpg 803w, https:\/\/www.medsyscon.com\/wp-content\/uploads\/2020\/12\/pic1-300x241.jpg 300w, https:\/\/www.medsyscon.com\/wp-content\/uploads\/2020\/12\/pic1-768x617.jpg 768w\" sizes=\"auto, (max-width: 803px) 100vw, 803px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">There are various spaghetti diagrams that show tortuous connections between PMS Plans (PMSP), Periodic Safety Update Reports (PSUR), Clinical Evaluation Reports (CER), Postmarket Clinical Follow-ups (PMCF), Summaries of Safety and Clinical Performance (SSCP), technical documents, Clinical Evaluation Plans (CEP), Benefit-Risk Analyses (BRA), etc. Looking at these activities as \u201cdocuments\u201d with inputs from certain other documents is good for making flowcharts. However, to really make sense of these, one must look at them from systems standpoint:<\/p>\n\n\n\n<ol class=\"wp-block-list\" type=\"1\"><li>How and at what point(s) does your PMS subsystem interface with the risk management subsystem and its various processes?<\/li><li>How and at what point(s) does your PMS subsystem interface with the clinical and\/or medical affairs subsystem and its various processes?<\/li><li>How and at what point(s) does your PMS subsystem interface with other relevant subsystems per your organizational context and its various processes?<\/li><li>How does information flow? How does data flow? How does knowledge flow? How does wisdom flow?<\/li><li>How is information converted to knowledge and wisdom? (i.e., How are incidents aggregated, analyzed, trended, and fed into the risk management file and benefit-risk analysis?)<\/li><\/ol>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.iso.org\/standard\/67942.html\" target=\"_blank\" rel=\"noreferrer noopener\">TIR 20416:2020<\/a> specifically identifies six functions that interface with PMS processes:<\/p>\n\n\n\n<ol class=\"wp-block-list\" type=\"1\"><li><strong>Design and Development:<\/strong> PMS data can provide input toward design changes of existing devices based on safety and quality of design features (e.g., failure rates attributed to design). PMS data can also be used to inform new product development projects for similar devices so that quality, risk avoidance, and reliability can be introduced by design in early stages.<\/li><li><strong>Clinical Evaluations:<\/strong> PMS data forms an integral part of the device\u2019s safety and performance conclusions. PMS is a rich data source that can supplement and complement the knowledge gained from clinical investigations of the device and help the manufacturer reach more accurate conclusions about benefit-risk.<\/li><li><strong>Activities to Meet Regulatory Requirements:<\/strong> Vigilance reporting should have a smooth and efficient interface with other PMS functions, notably complaint intake, clinical trials\/investigations, and postmarket incident trending. In addition, new premarket approvals and technical document updates also require analysis and summarization of PMS data.<\/li><li><strong>Improvement:<\/strong> PMS data should be linked actively to the corrective and preventive actions (CAPA) and other improvement vehicles not only to fix issues with device performance but also to capitalize on opportunities to expand on intended use, indications for use, or processes (logistics, training, etc.).<\/li><li><strong>Marketing and Sales:<\/strong> More decisions to award large contracts are being informed by postmarket data analysis. Clear, concise, and well-explained postmarket safety and performance analysis can become a great tool for advertisement of device performance. If the PMS function truly works well, the device marketability will keep becoming more and more attractive as the benefit-risk ratio improves.<\/li><li><strong>Risk Management:<\/strong> Part 3 in this article series will focus on risk management.<\/li><\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">All of the PMS processes are generating data, either continually or intermittently. Staff members from processes and subsystems within the organization that interface with PMS (e.g., the six listed above) are expecting a level of analysis on PMS data for their own decision-making purposes. There needs to be a high level of knowledge management from the PMS function to make sure that any organizational, strategic, or operational objectives tied to PMS data and its analysis are met without confusion or last-minute work.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">PMS knowledge management is a proactive, cross-functional process that includes holistic planning, checking, action, and standardization of creation, usage, sharing, and maintenance of organizational PMS data. TIR 20416:2020 identifies some sources of PMS data as:<\/p>\n\n\n\n<ol class=\"wp-block-list\" type=\"1\"><li>Complaints (including malfunction and adverse events)<\/li><li>Device maintenance\/refurbishing\/repair records<\/li><li>Device installation records<\/li><li>Analysis of returned device (with or without an associated complaint event)<\/li><li>Device explants<\/li><li>Medical device registries and publicly accessible databases (e.g., MAUDE, DAEN, MedSun, EUDAMED)<\/li><li>Clinical follow-up studies<\/li><li>Advisory notices<\/li><li>Scientific literature<\/li><li>Social and public media<\/li><li>Benchmarking data from conferences and tradeshows<\/li><li>Audits<\/li><li>Market surveillance (e.g., competitor research, customer preference surveys, patient group experiences, training programs, user feedback, etc.)\u201d<\/li><\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">Please find the complete article&nbsp; <a href=\"https:\/\/www.meddeviceonline.com\/doc\/risk-based-postmarket-surveillance-pms-in-the-age-of-eu-mdr-a-systems-approach-0001\"><strong>here<\/strong><\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For further information please get in touch with us:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"http:\/\/www.medsyscon.com\/en\">www.medsyscon.com\/en<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"mailto:info@medsyscon.com\">info@medsyscon.com<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">+49-176-57694801<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"254\" src=\"https:\/\/www.medsyscon.com\/wp-content\/uploads\/2020\/02\/Logo_MedSysCon_Medizintechnik_4C-1024x254.jpg\" alt=\"\" class=\"wp-image-1768\" srcset=\"https:\/\/www.medsyscon.com\/wp-content\/uploads\/2020\/02\/Logo_MedSysCon_Medizintechnik_4C-1024x254.jpg 1024w, https:\/\/www.medsyscon.com\/wp-content\/uploads\/2020\/02\/Logo_MedSysCon_Medizintechnik_4C-300x74.jpg 300w, https:\/\/www.medsyscon.com\/wp-content\/uploads\/2020\/02\/Logo_MedSysCon_Medizintechnik_4C-768x190.jpg 768w, https:\/\/www.medsyscon.com\/wp-content\/uploads\/2020\/02\/Logo_MedSysCon_Medizintechnik_4C.jpg 1356w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Jayet Moon, author of the book \u201cFoundations of Quality Risk Management\u201d, wrote in a Guest Column of Med Device Online: \u201cAs the central focus of the EU\u2019s Medical Device Regulations (MDR), postmarket surveillance (PMS) and its related processes and subsystems &#8230;<\/p>\n","protected":false},"author":5,"featured_media":1994,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[78],"tags":[],"class_list":["post-1989","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-regulatory-consulting"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.7 -
