FDA and industry recently got together to negotiate renewal of medical device user-fee legislation. However, they left out any provision for postmarket surveillance.Such a provision had been included in the original Medical Device User Fee and Modernization Act of 2002 (MDUFMA), but the Republican-led Congress did not fund it.
Most mass media headlines faulting FDA’s performance on postmarket product safety have focused on drugs. However, agency deficiencies in the device industry have also been featured. Drug-eluting stents, defibrillators, breast prostheses, heart valve implants, infusion pumps, and contact lens solutions have all captured media attention.
Indeed, concerns have been intense enough to prompt CDRH to commission a study on bar coding for medical devices. And, last November, center director Daniel Schultz announced a Postmarket Transformation Leadership Team to enhance device safety in the marketplace.
So why was this entire issue left out of the second round of user-fee legislation?
Enter the new Democratic majority on Capitol Hill in the form of House Committee on Energy and Commerce Health Subcommittee chairman Frank Pallone (D–NJ). In a May 16 hearing on MDUFMA II, as the reauthorization is called, he described postmarket surveillance activities as “noticeably absent from this proposal.â€
Asked to explain their absence, FDA assistant commissioner for policy Jeffrey Shuren explained the agency’s position. “If we can ensure adequate funding for the agency,†he said, “we will be in a fairly good place for postmarket safety.â€
Although the user-fee reauthorization does not specifically address postmarket activities, the fees will still support necessary surveillance activities, he explained. For example, Shuren said, past funding has allowed the agency to hire experts. These experts provide “greater expertise in a variety of fields that is then integrated into our postmarket safety activities. In addition, we have a little more protection on appropriations that will go to the rest of the program, which will cover the remaining postmarket safety activities.â€
Pallone asked whether the agency would support a congressional mandate that earmarked user fees for postmarket surveillance issues. Shuren said that FDA “would prefer [to] have the funding and then apply it as [it sees] fit.â€
In explaining the reauthorization, Shuren said, “MDUFMA was about growth. It was about progressively increasing the size of the device review program through rapidly increasing funding linked to progressively more-aggressive performance goals. For MDUFMA II, we are recommending changes to fine-tune the program.†This includes getting funding to maintain a stable device review program and continuing to improve performance that is attainable through seasoned review staff and process efficiencies.
Shuren also highlighted three areas for refinement. “First, for premarket review performance, we are proposing to meet more-rigorous goals that build on the progress we made in the first medical device user-fee program,†he said. “The result would be a shortened decision time for several types of applications, including those for the most innovative devices. In addition, we are proposing several qualitative goals to continue to enhance the device review process and to make it more transparent.†For example, FDA has proposed additional steps to facilitate the informal interactions with manufacturers called interactive reviews. Such steps would make public more information about FDA’s performance.
“Second, to ensure financial stability for the review program, we are recommending a reasoned increase in user-fee revenues in the first year,†Shuren said, “followed by annual increases of 8.5% for the four years thereafter.†This system could help ensure that FDA has adequate resources to maintain a device review program, while providing the predictability and the fees for the duration of MDUFMA. Also, the establishment of two new fees will generate about 50% of the total fee revenue. (The additional fees are an annual establishment registration fee and an annual fee for filing periodic reports.) This revenue should stabilize FDA’s funding, enable it to lower the application fees, and provide a larger fee discount for small businesses.
“Third, we are recommending modest changes to the third-party inspection program,†Shuren explained. The changes are designed to encourage industry participation while maintaining safeguards against conflicts of interest. In addition, he said, a successful third-party inspection program will enable FDA to better focus its inspectional resources on high-risk devices.
Refining MDUFMA
Jeffrey Shuren pointed out three changes that should be made in MDUFMA II. They are the following:
1. Meet more-rigorous premarket review performance goals.
2. After increasing user fees in the first year, annually increase fees 8.5% for four years thereafter.
3. Make changes to the third-party inspection program to encourage participation and avoid conflicts of interest.

Subcommittee member Henry Waxman (D–CA) urged that FDA be given more resources for device inspections. Since 2003, FDA has reduced medical device field investigators from 482 to 413, making it more difficult to perform mandated biennial GMP inspections. Shuren said that domestically, about 5500 facilities making Class II and Class III devices are eligible for biennial inspections. However, the agency is inspecting these firms only about once every four years.National Research Center for Women and Families president Diana Zuckerman urged lawmakers to add more device safety provisions in the legislation. She cited Bausch & Lomb’s recent problems with its 510(k)-cleared contact lens solution that caused eye infections and blindness. She said the agency should require clinical trials when potentially dangerous devices are modified. “MDUFMA II should make sure that the approval process protects consumers,†she said, complaining that performance goals would drastically speed up the 510(k) clearance process. (The goals would require 90% of 510(k)s to be reviewed within 90 days.) For premarket approval (PMA) application devices, review goals would also be faster. For those devices, 60% of PMAs and supplements would need to be completed within six months. Those time frames are considerably faster than what’s expected of drugs, she noted.
“MDUFMA II has performance goals for speed, but it needs performance goals for public health as well,†Zuckerman told the hearing. She noted that the user-fee reauthorization also lacks any fees for direct-to-consumer advertising reviews and adverse-event analyses. In addition, there are no fees for analyses to ensure that postmarketing commitment studies prove that products are safe. “Although FDA has flexibility to spend user-fee money however it wants, there’s just not enough money for all it needs to do.â€
FDA Alliance executive director Steven Grossman echoed the concerns about resources. He said that since 2003, FDA has “lost about 20% of its buying power and has nearly 1000 fewer employees supported by appropriated dollars.†These deficits make it hard for FDA to recruit and retain the “best and brightest.â€
Grossman said a $450 million increase in appropriated funding is needed to restore the agency to operational levels achieved in 2003. Of this, CDRH and related field activities should receive an increase of $72 million in FY 2008. “This would bring the center from its current $230 million to $302 million, not including user fees. Because devices employ cutting-edge science, CDRH needs these non-user-fee monies for additional staff to perform product reviews, assure pre- and postmarket safety, and facilitate innovative technology coming to market.â€
