As of the publication of this
article, 2019 has already seen recalls of twelve
medical devices. Most recently, Two Medical Technologies, Inc. recalled
automatic transport ventilators due to a
potential risk of fire. But these are likely not all of the devices
that should be recalled. The Food and Drug Administration (FDA) hid
reports about harm caused by medical devices. In its article
discussing these reports, Kaiser, a healthcare delivery system, profiled a
surgeon who was using a surgical stapler to seal tissue around someone’s
appendix, but the stapler locked up. Over two-thirds of surgeons he talked to
about this issue experienced a similar malfunction. The FDA apparently had
granted the makers of these staplers a special exemption “allowing them to file
reports of malfunctions in a database hidden
from doctors and from public view.” This database, MAUDE, includes
serious injury and malfunction reports for about 100 medical devices. More than
one million reports of malfunctions or harm spanning about fifteen years remain
in the database. The FDA has been notified of 5.4
million adverse events between 2008 and 2018. While some
malfunctions are openly reported, thousands more are hidden.
The FDA’s Center for Devices and
Radiological Health is tasked with regulating
medical devices. There are three risk categories that essentially determine the
level of scrutiny they receive during the regulation process. Class I devices
are not at all highly regulated, and do not
actually have to do what they claim to do as long as they are adequately
packaged and properly labeled. Class II devices—which are considered medium
risk and could hurt patients if misused—also do not receive a high level of
oversight, especially if it is a device that is substantially
equivalent to a device already allowed on the market. Class III
devices must go through a premarket authorization scientific review process
before approval. However, there are several loopholes
in the regulatory process. First, medical devices often are not tested in
humans before they are released on the market. Second, there is not systemic
way for the government, researchers, or patients to spot problems in the
process. Third, there are not many protections for patients who are harmed by
medical devices.
Class III devices are still not
being regulated enough. The FDA needs to re-evaluate its regulation process,
particularly for Class II and Class III devices. It does not seem that the
“substantially equivalent” test and the premarket authorization process are
working. These sorts of loopholes are creating problems in the medical field.
For instance, if the FDA was actually regulating medical devices, 80,000
deaths due to malfunctions could have been prevented. People would
potentially not be permanently paralyzed, burned, and otherwise permanently
damaged otherwise. Even when devices cause problems, they are rarely
pulled from the market.
The FDA may
not always know the extent of risk before the medical device reaches
the market. But there are ways to mitigate these problems before recalling the
devices. One surgeon has called for mandatory
registration of all implantable devices. The FDA has also called for
human
testing and, for at least one type of medical device, has required
companies to submit a report on devices already
on the market. The FDA recently said that it will start actively
watching how devices perform once on the market, rather than relying only on
patients to report problems. Hopefully in the coming years, the FDA will no
longer see huge medical device recalls.
