Assessing the Safety and Effectiveness of Devices after FDA Approval

Devices after FDA Approval

Pew research on U.S. Food and Drug Administration postmarket surveillance studies appeared in the October issue of The Journal of the American Medical Association Internal Medicine. Postmarket surveillance—monitoring the safety and effectiveness of products once they are on the market—allows FDA to more quickly identify problems and accurately measure device performance and clinical outcomes. 

The research found that study protocols frequently were not finalized at the time of approval, which contributes to delays in initiating and completing these studies. Additionally, small sample sizes and lack of availability of findings   limit the clinical usefulness of the studies.

One way to address some of the limitations identified by the authors—including Rita Redberg, a cardiologist at the University of California, San Francisco—is through the wider use of medical device registries, which can quickly and efficiently collect data on large numbers of patients.

Agenda for America

A collection of resources to help federal, state, and local decision-makers set an achievable agenda for all Americans

Data-driven policymaking is not just a tool for finding new solutions for emerging challenges, it makes government more effective and better able to serve the public interest. In the coming months, President Joe Biden and the 117th Congress will tackle a number of environmental, health, public safety, and fiscal and economic issues—nearly all of them complicated by the COVID-19 pandemic. To help solve specific, systemic problems in a nonpartisan fashion, Pew has compiled a series of briefings and recommendations based on our research, technical assistance, and advocacy work across America.

Data-driven policymaking is not just a tool for finding new solutions for difficult challenges. When states serve their traditional role as laboratories of innovation, they increase the American people’s confidence that the government they choose—no matter the size—can be effective, responsive, and in the public interest.
