The Wall Street Journal ran a piece this past week discussing how many medical providers apparently re-use various medical equipment to save money. Not just any medical equipment - but medical equipment labeled "single use." Sounds a little "iffy" to me - even though I understand the profit-motive of the medical device companies. Journalist Laura Landro reports,
In a bid to save costs and stem a rising tide of medical waste, hospitals are recycling a growing number of medical devices labeled as single-use, from scissors and scrubs to the sharp blades surgeons use to saw through bones.
Recycling medical devices labeled for single use is legal as long as certain Food and Drug Administration guidelines are followed. But the practice, which involves shipping devices to reprocessing facilities to be cleaned, sterilized and tested for reuse, has raised concerns about safety. Medical device makers say their single-use products are just that, and pose a higher risk of failure and harm when recycled. Reprocessing companies, hospital associations and environmental groups counter that the devices they reprocess are as safe as new thanks to modern sterilization methods, cost 40% to 60% less, and can eliminate thousands of tons of waste from landfills.
In January, after reviewing eight years of FDA data, the Government Accountability Office weighed in with a report concluding there is no evidence that reprocessed single-use devices create an elevated health risk for patients. About 100 devices -- just 2% of all devices labeled for single use -- are now reprocessed.
But while the GAO report tilts the debate strongly in favor of reprocessing and opens the door to more widespread use, device makers are sticking to their guns. They are lobbying in several states for legislation that would require health-care providers to obtain "informed consent" from a patient before using a reprocessed device during a procedure. Utah already has approved liability protections for original equipment makers, and other state bills include measures that would free original manufacturers from liability if a reprocessed device fails and causes injury or death.
Device makers maintain that their products labeled for single use aren't designed to hold up to harsh sterilization chemicals and processes. Even when the devices are sterilized, blood, tissue or other bodily fluids on porous surfaces and in tiny crevices could allow transmission of viral and bacterial infections, they say. In general, "single-use devices present an increased safety risk to patients because they are designed for optimal performance and safety in a single patient," says Tara Federici, vice president of technology and regulatory affairs at AdvaMed, a trade group that represents leading device makers.
For example, heart stabilizers, the devices used to position a beating heart during surgery, have hollow tubes and other parts that device manufacturers say could harbor blood and tissue and become weakened during reprocessing in ways that might not be evident during inspection. A study by the University of Minnesota of stabilizers made by Medtronic Inc. found that while new devices showed little or no manufacturing debris, a majority of reprocessed devices had corroded parts and traces of human hair and protein, bringing into question the effectiveness of the reprocessing efforts.
Last year, the FDA began requiring that reprocessed heart stabilizers undergo more rigorous premarket clearance reviews, and a Medtronic spokesman says the company plans to repeat the tests to see if the more stringent requirements improve performance. Until then, he says, the company stands by its position that the devices can't safely be reprocessed.
The Association of Medical Device Reprocessors, a trade group whose members reprocess the majority of devices, counters that it recycles only products made from rigid, hard metals or durable polymers and plastics that can safely be reused between two and five times, depending on the device. The group has petitioned the FDA to require new heart stabilizers to undergo the same premarket review as reprocessed ones, because the device itself is high-risk. Since 2001, the group notes, there have been 73 adverse events reported to the FDA involving devices used to stabilize the heart, including incidents in which pieces have broken off and fallen into the chest cavity.
Dan Vukelich, president of the group, says reprocessed devices can be safer in some cases because each must be inspected before reuse, while original manufacturers test new devices only in batches. He also contends that device makers label many products as single-use merely to be able to sell more new devices to hospitals and thwart competition -- a contention that medical device makers dismiss.
About $31.5 billion of single-use medical devices are sold annually in U.S. hospitals and surgery centers, of which around $150 million are recycled, according to Ascent Healthcare Solutions, a leading reprocessing company. John Grotting, Ascent's chief executive, estimates that about $3.6 billion of single-use devices are safe for reprocessing, which could save the health-care industry about $1.8 billion a year. Ascent hospital customers eliminated about 1,684 tons of waste from their local landfills last year, a 31% increase over 2006, by using reprocessed devices, Ascent says. . . . .
"Single-use labeling is a real scam for a lot of devices, and by not using reprocessed devices where possible it is wasteful and not environmentally responsive, since these items have to be disposed of as biomedical waste," says Kenneth Kizer, a consultant and former undersecretary for health at the U.S. Department of Veterans Affairs. "The reuse of medical devices that are labeled for single-use only is a well-established and safe practice regulated by the FDA and utilized by most of the top-ranked hospitals in the country."
Dr. Kizer testified last year at a congressional hearing that the VA could save up to $30 million in 2008 by using reprocessed medical devices. The VA, with 153 hospitals, has had a longstanding policy against the use of reprocessed devices on the grounds that it can't determine if they are safe, noting that manufacturers didn't design them to be used more than once and don't provide instructions on cleaning and sterilizing the devices. A spokesman says the VA reviews the policy from time to time but has no plans to change it at present.
The FDA has stepped up its oversight of reprocessing, including more plant inspections, after new legislation in 2002 began requiring devices to be labeled if they are reprocessed. The FDA says it is working on a new strategy for monitoring and communicating information about reprocessed devices, and conducting research on "acceptable" single-use device-cleaning criteria. . . .
Not quite sure about this money saving technique - I fear that it could lead to the situation we see in Nevada with all kinds of medical devices being "recycled" with harmful impacts.
