Life expectancy in the U.S. has markedly improved over the last century. At the turn of the 20th century, it was 

. By 2017, life expectancy at birth reached nearly 

. Advances in medical innovations are often cited as “one of the greatest contributors” to this progress.

These long-term trends provide important perspective for Congress as it considers re-authorizing the Medical Device User Fee and Modernization Act of 2002 – the next authorization is referred to as MDUFA V.

All new medical devices – the wide range of products that are used to diagnose, treat, monitor, or prevent diseases and conditions – must obtain U.S. Food & Drug Administration (FDA) authorization before the products can be marketed and sold in the United States. Prior to MDUFA, FDA’s review process was widely viewed as inefficient, time consuming, and the FDA rarely met the required deadlines.

As a result of these inefficiencies, patients’ access to potentially lifesaving or life-enhancing medical devices were unnecessarily delayed, harming health outcomes. From the companies’ perspectives, the delays created uncertainties that made marketing their products more difficult and complicated the process of conducting follow-up studies.

MDUFA is a win-win-win policy that reduces these problems.

How Industry-FDA Cooperation Removed Medical Imaging Device Delivery Delays

For the FDA, MDUFA ensures that the agency has access to the necessary resources to improve its efficiencies. Consider that the 

 for devices that are “substantially equivalent” to a device already on the market (510(k) applications) has fallen from 154 days in 2010 (including the time spent by the FDA and time spent by the applicant responding to the FDAs requests) to 124 days in 2019. The decision time for novel medical devices (PMAs) has been more volatile, but still fell from 467 days in 2013 to 217 days in 2019. Thanks to the resources provided by MDUFA, the FDA is largely meeting is required efficiency goals.

For the manufacturers, the improved speed and predictability of the approval process improves manufacturers’ efficiencies and planning processes. Perhaps most importantly, the expedited review process provides patients with faster access to new medical devices. 

, these new devices include better heart valves, devices that enable minimally invasive spinal correction, and better glucose monitors.

These results strongly support the argument that MDUFA V should be authorized by Congress. The terms of that reauthorization are a bit more controversial.

MDUFA’s benefits are enabled by the act’s user fee structure. There are, undoubtedly, strong arguments in favor of funding the FDA’s review process by levying user fees on the manufacturers submitting devices for approval. There are equally strong arguments that user fees should only partially fund the review process and general tax revenues should also fund a substantial portion of these costs.

It is commonly accepted that government agencies 

 when a limited number of people or businesses benefit from the public service. Taxes, on the other hand, are appropriate when the general population benefits from the public service.

The benefits from the FDA’s medical device review process contain both of these elements. Medical device manufacturers benefit greatly from an efficient review process, but so does the broad patient population. The current blended revenue structure that funds the review process with both MDUFA user fees and general tax revenues balances both types of benefits.

Over time, the revenue structure has been tilting toward an excessive 

 rather than general tax revenues. When first implemented, user fees accounted for approximately one-fifth of total program revenues. The implementation of new fees and increases in rates has caused user fee revenues to grow at double-digit rates and now account for around 44 percent of total revenues.

This excessive growth in user fees is becoming an excessive tax on manufacturers that, if not appropriately managed, will reduce their efficiencies and incent wasteful expenditures on programs that do not enhance the FDA’s mission of performing a comprehensive and timely safety review process of new medical devices. The consequence will be a higher-cost, less efficient, FDA.

It is imperative that Congress recognize these considerations in its upcoming MDUFA reauthorization process. While reauthorizing MDUFA is an important public health policy, the user fee authority should not be used as a slush fund to authorize ancillary programs that do not enhance the agency’s prime directive.
