From infant formula to contrast dye for CT scans, ongoing healthcare product shortages highlight continuing US supply chain and manufacturing issues
Medical laboratory directors and pathologists have firsthand knowledge of COVID-19 pandemic-driven supply chain issues, having faced backlogs for everything from pipettes and transport media to personal protective equipment (PPE). But the latest shortage impacting blood collection tubes is another example of why it is important to manufacture key products—including clinical laboratory tests, analyzers, and consumables—domestically.
On January 19, 2022, the federal Food and Drug Administration (FDA) issued a Letter to Healthcare Providers and Laboratory Personnel recommending “conservation strategies” to minimize blood collection tube use because of “significant disruptions” in supplies due to COVID-19-increased demand and “recent vendor supply challenges.”
“The FDA updated the device shortage list to include all blood specimen collection tubes (product codes GIM and JKA),” the letter noted.
This announcement followed a similar June 10, 2021, Letter to Healthcare Providers and Laboratory Personnel that stated the FDA was aware “that the US is experiencing significant interruptions in the supply of sodium citrate blood specimen collection (light blue top) tubes because of an increase in demand during the COVID-19 public health emergency and recent vendor supply challenges.”
A spokesperson for Becton-Dickinson (BD), a manufacturer of blood specimen collection products, told Forbes that the COVID-19 pandemic caused “the most unpredictable demand that BD has experienced in our company’s history.” The spokesperson added, “Worldwide, BD produced nearly a half a billion additional blood tubes in 2021 versus 2020 … Like every business across every industry around the world, BD is experiencing limited availability of and access to raw materials, shipping and transportation delays, and labor shortages, which hinders our ability to ramp production.”
“It’s also a challenge because we’ve moved to just-in-time (JIT) inventory across all sectors, including labs … They outdate just like food [and] are no longer fresh. [The product] is no longer reliable and you can’t use it. So, we can’t stockpile either,” Nielsen told Forbes.
Shortages Hit Other Critical Healthcare Sectors
But shortages of supplies and equipment have spread beyond the clinical laboratory. Intravenous contrast—which contains iodine and is used to improve the accuracy of CT scans and exclude life-threatening conditions such as cancer—has been in short supply since GE Healthcare shut down its manufacturing facility in Shanghai, China, during the city’s two-month pandemic lockdown that began in early April.
“This isn’t an ancillary tool. This is something that’s used many, many times every day for both lifesaving decisions in the setting of trauma and for managing cancer patients and determining the appropriate care for them,” he added.
US Rep. Rosa DeLauro (above), lamented the fact these vital products are not being made in sufficient quantities in the US. “In the wealthiest nation on Earth, there should be no reason doctors are forced to ration lifesaving medical scans to compensate for a shortage of material,” DeLauro told The New York Times. “We are seeing supply chains break down because of consolidated industries experiencing manufacturing shortages and offshoring American jobs to China.” Clinical laboratory managers have first-hand knowledge of the severity of supply shortages.

GE Healthcare is one of four companies that supply iodine-containing contrast to the United States, but the other three manufacturers have been unable to scale-up and offset the shortage.
By June 14, 2022, the Shanghai facility had returned to 100% production capacity following the easing of local COVID restrictions, according to a GE Healthcare statement. But shortages remain.
“There is still the challenge of bringing the contrast media across the ocean and distributing it to healthcare facilities across the nation,” Nancy Foster, the American Hospital Association’s (AHA) Vice President of Quality and Patient Safety Policy, told CNN.
“The hospital association estimates that about half of all hospitals in the United States rely on GE for contrast dye to perform about 20 million scans a year, or about 385,000 scans each week,” CNN reported.
Critical Medical Products Must be Manufactured Domestically
“We’ve been having shortages throughout the pandemic. At the very beginning of the pandemic, it was PPE shortages,” Jain said. “Now, we have contrast shortages and formula shortages for babies.”
The infant formula crisis is the other headline grabbing news in recent weeks. Three companies—Abbott, Reckitt, and Gerber—manufacture 95% of the baby formula sold in the US, with Abbott controlling roughly 42% of the nation’s supply, CNN reported.
“Initially, this problem affected those who are on more specialized formulas or had nutritional issues,” Stephanie Seger, Director of Government Relations at Children’s Mercy Hospital in Kansas City, Mo., told CNN. ‘Then the gap, or the emptiness on the shelves, increased to the point where it’s now any formula. It’s now any parent of any baby.”
The Biden administration took steps in May to increase the supply of imported formula, but like the Intravenous contrast shortage, the problem has not been solved.
The COVID-19 pandemic has served to underscore the serious issues affecting supply chains for hospital, medical laboratory, and other critical supplies. While no quick fix has appeared on the horizon, the clinical laboratory industry should take steps now to work toward long-term solutions.
CDC estimates that 92% of cancers caused by HPV could be eliminated in the US if HPV vaccination recommendations in this country are followed
Medical
laboratories in the United States once processed as many as 55-million Pap tests each year. However,
the need for cervical cancer screening tests is diminishing. That’s primarily because
the human
papilloma virus (HPV) vaccination effectively eliminates new cases of
cervical cancer. At least, that’s what’s happening in Australia.
When it was introduced in 2007, Australia’s nationwide
publicly-funded HPV
vaccination program only included girls, but was extended to boys in 2013.
Today, it is being credited with helping slash the country’s cervical cancer
rates.
Research published in The
Lancet Public Health (Lancet) predicts cervical cancer could be
eliminated in Australia by 2028 if current vaccination rates and screening
programs continue. Cervical cancer would be classified as effectively
eliminated once there are four or fewer new cases per 100,000 women each year.
These developments will be of interests to pathologists and cytotechnologists in
the United States.
“From the beginning, I think the [Australian] government
successfully positioned the advent of HPV vaccination as a wonderful package
that had a beneficial effect for the population,” Karen
Canfell, PhD, Director, Cancer Research Division at Cancer Council New
South Wales, Australia, and Adjunct Professor, University
of Sydney, told the Texas
Tribune. “It was celebrated for that reason, and it was a great public
health success.”
In addition to high vaccination rates, the Lancet
study notes that last year Australia transitioned from cytology-based cervical screening
every two years for women aged 18 to 69 years, to primary HPV testing every
five years for women aged 25 to 69 and exit testing for women aged 70 to 74
years.
“Large-scale clinical trials and detailed modelling suggest
that primary HPV screening is more effective at detecting cervical
abnormalities and preventing cervical cancer than screening with cytology at
shorter intervals,” the Lancet study states.
The incidence of cervical cancer in Australia now stands at
seven cases per 100,000. That’s about half the global average. The country is
on pace to see cervical cancer officially considered a “rare” cancer by 2020,
when rates are projected to drop to fewer than six new cases per 100,000 women.
US Cervical Cancer Rates
In Texas, meanwhile, the state’s failure to embrace HPV
vaccination is being blamed for slowing potential improvements in cervical
cancer rates. In 2007, Texas lawmakers rejected legislation that would have
mandated girls entering sixth grade be vaccinated for HPV. The Texas Tribune
reports that, in the decade that followed, vaccination rates remained stagnant
with only about 40% of Texans between 13 and 17 years old having been vaccinated
for HPV by 2017.
Though Texas has a similar size population as Australia, the
state’s low vaccination rates have meant cervical cancer rates have shown
little improvement. Statistics compiled by the federal Centers for Disease Control
and Prevention (CDC) show that Texas’ age-adjusted rate of new cervical
cancer cases sits at 9.2 per 100,000 women—unchanged since 2006.
Texas has the fifth highest rate of cervical cancer in the
nation, according to the CDC.
Texas State Rep. Jessica Farrar, a Democrat from Houston, maintains Texas should have followed the example of Australia, which in 2007 began a publicly funded HPV vaccination program that has the country on the verge of eliminating cervical cancer by 2028. Texas rejected mandatory HPV vaccinations and now has one of the highest cervical cancer rates in the US. “This is a preventable disease, and we should and can be doing more,” she told the Texas Tribune. “Here we are 12 years later, and look where we could’ve been, but because of certain beliefs, we’re suffering from cancers that could have been avoided.” (Photo copyright: The Texas Tribune.)
Lois Ramondetta,
MD, Professor of Gynecologic Oncology at MD Anderson Cancer Center in Houston,
told the Texas Tribune the state ignored an opportunity that Australia
seized. “[Australia] embraced the vaccine at that time, and our fear kind of
began around then,” Ramondetta said. “Really, vaccination in general has just
gone down the tube since then.”
CDC Study Pushes HPV Vaccination Recommendations in US
Texas is not the only state failing to capitalize on the HPV
vaccine’s cancer-curing promise. The CDC recently stated in a news
release announcing a recent study that 92% of cancers caused by HPV could
be eliminated if HPV vaccine recommendations were followed. CDC published the
study in its Morbidity
and Mortality Weekly Report.
HPV is a common virus that is linked to not only cervical
cancer but also cancers of the penis, head, and neck, as well as conditions
like genital warts. Though the CDC recommends children get the two-dose vaccine
at ages 11-12, the study findings indicate that only 51% of teens ages 11 to 17
have received the recommended doses of HPV vaccine, a 2% increase from 2017 to
2018.
“A future without HPV cancers is within reach, but urgent
action is needed to improve vaccine coverage rates,” Brett
Giroir, MD, Assistant Secretary for Health, US Department of Health and
Human Services (HHS), stated in the CDC news release. “Increasing HPV
vaccination overage to 80% has been and will continue to be a priority
initiative for HHS, and we will continue to work with our governmental and
private sector partners to make this a reality.”
Can Australia Eliminate Cervical Cancer?
University of Queensland Professor Ian Frazer, MD, who
co-authored the Lancet Public Health study, believes Australia is on the
verge not only of eliminating cervical cancer, but also eradicating the HPV
virus itself.
“Because this human papillomavirus only infects humans, and
the vaccine program prevents the spread of the virus, eventually we’ll get rid
of it, like we did with smallpox,” Frazer told The
Age.
“It’s not going to happen in my lifetime,” he added. “But it
could happen in the lifetime of my kids if they go about it the right way.”
If Australia’s combination of high HPV vaccination rates and
new HPV screening program succeeds in effectively eliminating cervical cancer,
clinical laboratories in this country should expect stepped-up efforts to
increase HPV vaccination rates in the United States. A renewed focus on reducing—and
ultimately eliminating—cervical cancer, could lead to fewer or less-frequently
performed Pap tests as part of cervical cancer screening protocols.
