Description of CME Course

Importance  US law generally requires testing of high-risk medical devices prior to approval, as well as premarket evaluation of moderate-risk medical devices, with the goal of ensuring that the benefits of these products exceed their risks. The US Food and Drug Administration (FDA) attempts to balance the need for evidence generation with an approval process that facilitates access and encourages innovation.

Objective  To review the development of laws and standards affecting the evaluation and oversight of medical devices by the US regulatory system and the outcomes of this system from 1976 to 2020.

Evidence Review  Laws enacted by US Congress and regulations promulgated by the FDA through 2020; databases maintained by the FDA of device authorizations from 1976 to 2020; and annual reports of user fees paid to the FDA by industry.

Findings  Since Congress and the FDA initiated premarket review of medical devices in 1976, some fundamental innovations in the device regulation system have included special pathways to accelerate availability of investigational devices, more flexible evidence and review requirements, and increased funding to the FDA through industry-paid user fees. From 1987 to 2020, the annual number of novel devices granted premarket approval (which excludes supplements) ranged from 8 to 56 (median, 32), and the number of clearances for 510(k) devices (those that are “substantially equivalent” to marketed devices) ranged from 2804 to 5762 (median, 3404). User fee funding for devices was established in 2002 and annual fees collected increased from $30 million in 2003 (in 2019 dollars) to more than $208 million in 2019; this represented 43% of FDA funding related to the review of medical devices. Although many new devices have led to considerable patient benefit, such as hypodermic needles and magnetic resonance imaging machines, important adverse events caused by some devices, such as an implanted device for birth control and a surgical mesh implant for pelvic organ prolapse, have led to calls to reexamine the regulatory system for such products.

Conclusions and Relevance  Over the last 45 years, medical device regulation has become more complex, with more regulatory pathways and greater variations in the evidence and controls required for authorization. Increased FDA support from industry and concern about flexible authorization requirements reflect the tension between efficient access and the need for assurances that products will safely benefit patients.
