What does DPS do? Purpose: To conduct global post-market surveillance of medical devices and related emerging technologies through the regulation, collection, integration, and dissemination of adverse event data to identify and communicate actual and/or potential public health risks to FDA and public stakeholders. How we achieve our goal: Establish, interpret, and enforce requirements for medical device reporting (21 CFR Part 803Medical Device Reporting); and provide outreach and education to FDA and public stakeholders to help them understand the requirements of the medical device reporting regulation. Monitor, analyze and synthesize adverse event data to identify signals (of new device issues) and trends (of known device issues); and to ensure that CDRH effectively uses adverse event report data in premarket review, postmarket evaluation studies, compliance and enforcement matters, and timely public health communications in support of the CDRH mission.
Lead the continuous refinement and maintenance of the IT postmarket infrastructure to efficiently receive, process, retrieve , and analyze adverse event data in support of CDRH and FDA offices. 2 Division of Postmarket Surveillance M-CERSI Workshop Envisioning the Future of Mobile Informatics Medical Device Landscape 3 Division of Postmarket Surveillance M-CERSI Workshop Envisioning the Future of Mobile Informatics Medical Device Landscape 4 Division of Postmarket Surveillance M-CERSI Workshop Envisioning the Future of Mobile Informatics
