Recent Separate Business Transactions by Fujifilm and GE Healthcare Suggest Bullish Outlook for Faster Adoption of Digital Pathology

Fujifilm acquired Inspirata’s Dynamyx digital pathology technology and business while GE Healthcare announced a partnership with Tribun Health in Europe

Clinical pathology laboratories, especially in the US, have been slow to adopt digital imaging systems. But recent industry deals suggest that the market may soon heat up, at least in the eyes of vendors. These collaborators may hope that, by integrating diagnostic data, the accuracy and productivity of anatomic pathologists will improve while also shortening the time to diagnosis.

In a December press release, Tokyo-based Fujifilm announced it acquired the global digital pathology business of Inspirata, including its Dynamyx digital pathology system. Inspirata is a Tampa-based cancer informatics company.

In the press release, Fujifilm stated that 85% of US healthcare organizations use analog systems for pathology. That compares with 86% in Europe and 90% in Asia, the company stated.

“Acquiring Inspirata’s digital pathology business allows Fujifilm to be an even stronger healthcare partner—bridging a technological gap between pathology, radiology, and oncology to facilitate a more collaborative approach to care delivery across the enterprise,” said Fujifilm CEO and president Teiichi Goto in the press release.

The press release cited data from Signify Research, a healthcare technology marketing data firm that is predicting the global market for digital pathology systems would double from $320 million in 2021 to $640 million by 2025.

Fujifilm previously had a deal with Inspirata to sell the Dynamyx system exclusively in the UK, Italy, Spain, Portugal, Belgium, the Netherlands, and Luxembourg, an August press release noted.

“A $320 million global industry in 2021 projected to reach $640 million by 2025, the rising number of cancer cases and the demonstrated benefits of digital pathology are fueling significant demand and market growth in the hospital and pharmaceutical industries,” said Henry Izawa (above), president and CEO, Fujifilm Healthcare Americas Corporation, in a press release. “These evolving clinical needs fuel Fujifilm’s investment and innovation in the digital revolution, and we look forward to introducing Dynamyx and its host of unique features and benefits to our Synapse customers and prospects as we strive to enable more efficient medical diagnosis and high-quality care.” (Photo copyright: LinkedIn.)

GE Healthcare Partners with Tribun Health

The Fujifilm acquisition followed an October 18 announcement of a collaboration between GE Healthcare and digital pathology company Tribun Health in Europe to provide an interface between the latter’s digital pathology software and GE Healthcare’s Edison Datalogue image-management system.

In announcing their new collaboration, GE Healthcare and Tribun Health said the integration of their systems—Edison Datalogue and the Tribun Health suite—would foster collaboration between pathologists and clinicians by providing a consolidated location for imaging records. This capability is especially important in oncology, they said.

“The oncology care pathway is one of the most complex with multiple steps involving a variety of specialists, complex tools, frequent decisions, and large data sets,” said GE Healthcare CEO of Enterprise Digital Solutions Nalinikanth Gollagunta in a GE press release. “With this digital pathology collaboration, we continue our journey towards simplifying the oncology care pathway with improved data management, the digitization of pathology, and streamlined data access.”

Tribun Health, based in Paris, France, offers a digital pathology platform that incorporates a camera system, artificial intelligence (AI)-based analysis, remote collaboration, and storage management, plus integration with third-party automation apps.

GE Healthcare claims that Edison Datalogue has the largest share of the Vendor Neutral Archive (VNA) market. That term refers to image archiving systems that use standard formats and interfaces instead of proprietary formats. They are an alternative to the more widely used Picture Archiving and Communications Systems (PACS) used in medical imaging.

The collaboration between the companies “is probably a strategic move to position GE as an integrator of imaging data and digital pathology data in oncology,” said Robert Michel Editor-in-Chief of Dark Daily and its sister publication The Dark Report.

GE’s History with Dynamyx

This is not GE Healthcare’s first foray into digital pathology. In fact, the company had a major hand in launching the very Dynamyx system that Fujifilm recently acquired.

Dynamyx was originally developed by digital pathology technology company Omnyx, LLC, which was a joint venture formed in 2008 between GE Healthcare and the University of Pittsburgh Medical Center (UPMC).

In “GE Healthcare Sells Omnyx to Inspirata,” The Dark Report interviewed Inspirata CEO Satish Sanan who at that time said the acquisition would allow his company to offer “a fully integrated, end-to-end digital pathology solution” in Canada and Europe. But GE Healthcare chose to end the partnership in 2016, citing regulatory uncertainty and variable global demand. Two years later, GE sold Omnyx to Inspirata.

GE Healthcare’s new collaboration with Tribun Health shows that the company “still recognizes the value of the pathology data in cancer diagnosis and wants to be in a position to manage that digital pathology data,” Michel said.

Fujifilm’s Plans

Fujifilm said it will incorporate Dynamyx into its Synapse Enterprise Imaging suite, which includes VNA, Radiology PACS, and Cardiology PACS. “Future releases of Dynamyx will also create opportunities for Fujifilm to support pharmaceutical and contract research organizations with toxicity testing data management for drug development,” the company stated in the press release.

US-based subsidiary Fujifilm Healthcare Americas Corporation will handle future development of the Dynamyx system. In the US, the system is currently cleared for the US Food and Drug Administration (FDA) for use with Leica’s Aperio AT2 DX scanner and Philips’ Ultra Fast Scanner.

With its recent moves into digital pathology, Fujifilm will be taking on major competitors including Philips, Danaher, and Roche, MedTech Dive reported.

Healthcare Experts Say Consumers Are Ready for Self-Test Flu Kits, But Are Physicians and Clinical Laboratories Ready to Let That Cat Out of the Bag?     

Clinical laboratories could play a key role in helping users collect their samples correctly, interpret results, and transfer flu test data to their health records

Clinical laboratories may have another opportunity to provide service to their clients and the physicians who treat them. With the success of at-home COVID-19 testing, consumer demand for self-tests is changing and advances in diagnostic technology now make it feasible to make more influenza (flu) tests available for consumers to buy and use at home.

At-home tests for SARS-CoV-2 can be found at pharmacies all across America. But that’s not the case with tests for influenza.

Should self-test flu kits eventually become available and common, clinical laboratories could offer the service of helping consumers understand:

  • that the test was conducted correctly (specimen collection and analysis),
  • that the result is accurate and reproducible, and
  • how to understand the results.

Clinical laboratories also could collect and input the results into their laboratory information system (LIS), then send those results to the patients’ electronic health record (EHR) at their physician’s clinic.

Christina Yen, MD

“Home flu testing would ensure that those who do need and receive antiviral medication for influenza are the ones who need it the most,” and that “we are making our treatment decisions based on data,” infectious disease specialist Christina Yen, MD (above), University of Texas Southwestern Medical Center, told STAT News. At-home flu self-tests could also bring opportunities for clinical laboratories to provide service to healthcare consumers and the physicians who treat them.

Pros and Cons of Consumers Doing At-home Influenza Testing

According to the federal Centers for Disease Control and Prevention (CDC), COVID-19 and influenza are both upper respiratory illnesses with similar symptoms. So, why don’t we have more at-home flu tests available? Partly because at-home testing is a relatively new phenomenon in modern healthcare.

“It’s really rare, and it’s really new that people are allowed to know about what’s happening inside their body without a physician in the middle,” Harvard epidemiologist Michael Mina, MD, PhD, told STAT News. The article uses the example of at-home pregnancy tests. Despite a prototype for an at-home pregnancy test being created in 1967, it took another decade before an over-the-counter pregnancy test became available to the public.

“The general thinking was, ‘How could a woman possibly know what to do if she found out she was pregnant on her own without a doctor in the room?’ That is a ridiculous concern because women have been doing that for millions of years,” Mina added.

So, why be cautious when it comes to giving patients the option of at-home flu testing?

There are some cons to at-home influenza tests. Average citizens are not clinical laboratory professionals. They might obtain too little sample for an accurate reading or read the results incorrectly. Then, there is the possibility for false-negatives or false-positives.

An at-home test user is not likely to consider the possibility of a false result, however clinicians look at the situation with more nuance. If the patient was still symptomatic or in a high-risk community, the provider could administer a more sensitive medical laboratory test to confirm the previous test results.

There are other concerns about at-home testing as well. Another STAT News article titled, “Growing Use of Home COVID-19 Tests Leaves Health Agencies in the Dark about Unreported Cases,” reported on a superspreading event that health officials did not know about: a Phish concert on Halloween.

“In a Facebook post from mid-November with hundreds of responses, concertgoers compared symptoms and positive test results, many of those from tests taken at home. But those data weren’t added to state public health tallies of COVID’s spread,” STAT News noted.

The larger concern is that samples obtained by at-home self-test users are not submitted for genomic sequencing. This could lead to incomplete data and delay identifying new variants of the coronavirus in communities.

“If nobody’s reporting the tests, are we really getting the information we need?” Atul Grover, MD, PhD, Executive Director of the Association of American Medical Colleges Research and Action Institute, told STAT News. “We have no idea what the true positivity rate is.”

Another barrier to at-home flu testing is that rapid influenza diagnostic testing can be unreliable. In 2009, the rapid influenza tests could only detect the H1N1 influenza virus in a mere 11% of samples, STAT News reported. Because of this, the FDA now requires manufacturers to test their rapid tests against eight different strains that change every year depending upon which strains are prevalent. This could present a problem if individuals use leftover tests from the previous flu season.

Do Pros of At-home Testing Outweigh the Cons?

At-home testing is convenient and makes testing more accessible to patients who may not be able to get to a clinic. Being able to test at home also encourages individuals to take precautions necessary to stop the spread of whichever illness they may have. Given the similarities in symptoms between influenza and COVID-19, people could benefit from having tools at home that correctly identify their illness.

At-home COVID-19 tests are here to stay, and at-home influenza tests may be on the way soon. Clinical laboratories could play an important role in educating the public on the correct handling of these tests.

Federal EKRA Law Continues to Cause Uncertainty in Clinical Laboratory Sales Compliance

Healthcare attorneys advise medical laboratory leaders to ensure staff understand difference between EKRA and other federal fraud laws, such as the Anti-kickback Statute

More than four years have passed since Congress passed the law and yet the Eliminating Kickbacks in Recovery Act of 2018 (EKRA) continues to cause anxiety and confusion. In particular are the differences in the safe harbors between the federal Anti-Kickback Statute (AKS) and Stark Law versus EKRA. This creates uncertainty among clinical laboratory leaders as they try to understand how these disparate federal laws affect business referrals for medical testing.

According to a news alert from Tampa Bay, Florida-based law firm, Holland and Knight, “EKRA was enacted as part of comprehensive legislation designed to address the opioid crisis and fraudulent practices occurring in the sober home industry.” However, “In the four years since EKRA’s enactment, US Department of Justice (DOJ) enforcement actions have broadened EKRA’s scope beyond reducing fraud in the addiction treatment industry to include all clinical laboratory activities, including COVID-19 testing.”

It is important that medical laboratory leaders understand this law. New cases are showing up and it would be wise for clinical laboratory managers to review their EKRA/AKS/Stark Law compliance with their legal counsels.

David Gee

“Keeping in mind that [EKRA is] a criminal statute, clinical laboratories need to take steps to demonstrate that they’re not intending to break the law,” said attorney David Gee, a partner at Davis Wright Tremaine, in an exclusive interview with The Dark Report. “[Lab leaders should] think about what they can do to make their sales compensation program avoid the things the government has had such a problem with, even if they’re not sure exactly how to compensate under the language of EKRA or how they’re supposed to develop a useful incentive compensation plan when they can’t pay commissions.” David Gee will be speaking about laboratory regulations and compliance at the upcoming Executive War College in New Orleans on April 25-26, 2023.

How Does EKRA Affect Clinical Laboratories?

The federal EKRA statute—originally enacted to address healthcare fraud in addiction treatment facilities—was “expansively drafted to also apply to clinical laboratories,” according to New York-based law firm, Epstein Becker and Green. As such, EKRA “applies to improper referrals for any ‘service,’ regardless of the payor. … public as well as private insurance plans, and even self-pay patients, fall within the reach of the statute.”

In “Revised Stark Law, Anti-Kickback Statute Rules Are Good News for Labs,” Dark Daily’s sister publication The Dark Report noted that EKRA creates criminal penalties for any individual who solicits or receives any remuneration for referring a patient to a recovery home, clinical treatment facility, or clinical laboratory, or who pays or offers any remuneration to induce a referral.

According to Epstein Becker and Green, EKRA:

  • Applies to clinical laboratories, not just toxicology labs.
  • Has relevance to all payers: Medicare, Medicaid, private insurance plans, and self-pay.
  • Is a criminal statute with “extreme penalties” such as 10 years in prison and $200,000 fine per occurrence.
  • Exceptions are not concurrent with AKS.
  • Areas being scrutinized include COVID-19 testing, toxicology, allergy, cardiac, and genetic tests.

“For many clinical laboratories, a single enforcement action could have a disastrous effect on their business. And unlike other healthcare fraud and abuse statutes, such as the AKA, exceptions are very limited,” Epstein Becker and Green legal experts noted.

“Therefore, a lab could potentially find itself protected under an AKS safe harbor and still potentially be in violation of EKRA,” they continued. “The US Department of Health and Human Services (HHS) and the DOJ have not provided any clarity regarding this statute (EKRA). Without this much needed guidance clinical laboratories have been left wondering what they need to do to avoid liability.”

EKRA versus AKS and Stark Law

HHS compared AKS and the Stark Law (but not EKRA) by noting on its website prohibition, penalties, exceptions, and applicable federal healthcare programs for each federal law: 

  • AKS has criminal fines of up to $25,000 per violation and up to a five-year prison term, as well as civil penalties.
  • The Stark Law has civil penalties only.
  • AKS prohibits anyone from “offering, paying, soliciting, or receiving anything of value to induce or reward referrals or generate federal healthcare program business.”
  • The Stark Law addresses referrals from physicians and prohibits the doctors “from referring Medicare patients for designated health services to an entity with which the physician has a financial relationship.”

EKRA is more restrictive than AKS, as it prohibits some compensation that AKS allows, healthcare attorney Emily Johnson of McDonald Hopkins in Chicago told The Dark Report.

“Specifically, AKS includes a safe harbor for bona fide employees that gives an employer wide discretion in how employees are paid, including permitting percentage-based compensation,” Johnson wrote in a Dark Daily Coding, Billing, and Collections Special Report, titled, “Getting Paid for COVID-19 Test Claims: What Every Clinical Lab Needs to Know to Maximize Collected Dollars.”  

EKRA Cases May Inform Clinical Laboratory Leaders

Recent enforcement actions may help lab leaders better understand EKRA’s reach. According to Holland and Knight:

  • Malena Lepetich of Belle Isle, Louisiana, owner and CEO of MedLogic LLC in Baton Rouge, was indicted in a $15 million healthcare fraud scheme for “allegedly offering to pay kickbacks for COVID-19 specimens and respiratory pathogen testing.”
  • In S-G Labs Hawaii, LLC v. Graves, a federal court concluded the laboratory recruiter’s contract “did not violate EKRA because the recruiter was not referring individual patients but rather marketing to doctors. According to the court, EKRA only prohibits percentage-based compensation to marketers based on direct patient referrals.”
  • In another federal case, United States v. Mark Schena, the court’s rule on prohibition of direct and indirect referrals of patients to clinical labs sent a strong signal “that EKRA most likely prohibits clinical laboratories from paying their marketers percentage-based compensation, regardless of whether the marketer targets doctors or prospective patients.”

What can medical laboratory leaders do to ensure compliance with the EKRA law?

In EKRA Compliance, Law and Regulations for 2023, Dallas law firm Oberheiden P.C., advised clinical laboratories (as well as recovery homes and clinical treatment facilities) to have EKRA policies and procedure in place, and to reach out to staff (employed and contracted) to build awareness of statute prohibitions and risks of non-compliance.

One other useful resource for clinical laboratory executives and pathologists with management oversight of their labs’ marketing and sales programs is the upcoming Executive War College on Diagnostics, Clinical Laboratory, and Pathology Management. The conference takes place on April 25-26, 2023, at the Hyatt Regency in New Orleans. A panel of attorneys with deep experience in lab law and compliance will discuss issues associated with EKRA, the Anti-Kickback Statutes, and the Stark self-referral law.

High School Students in Upstate New York Learn 60 Critical Medical Laboratory Skills

Program launched by a Rochester-area technical center is intended to provide early study for students interested in a career in clinical laboratory medicine

Acute shortages of clinical laboratory staff across all types of skills is one of the big stories of this new year. It is also triggering unconventional approaches to reach students in high school and interest them in careers as medical technologists (MTs). One such example is a high school in New York that now offers a top-level medical laboratory program designed to create interest—then train—high school students for a career in laboratory medicine.

A recent CLP podcast, titled, “Has a High School Found the Solution to the Laboratorian Shortage?” outlined the Medical Laboratory Assisting and Phlebotomy program that is offered to students at Western Monroe and Orleans Counties (WEMOCO) Career and Technical Center in Spencerport, New York, a suburb of Rochester.

“With the acute shortage of medical technologists, this effort by one high school to reach students early and encourage them to pursue a career in clinical laboratory medicine should be of interest to all laboratory professionals,” said Robert Michel, Editor-in-Chief of Dark Daily and its sister publication The Dark Report.

Jim Payne

“Our juniors and seniors in high school will learn about 60 employable laboratory skills,” said Jim Payne (above), a Medical Laboratory Assisting and Phlebotomy program instructor at WEMOCO. “They learn not only medical laboratory skills, but [the skills] are transferable to biotechnology, to chemical labs, food labs, environmental labs, research, forensics, and so on. The goal is each individual student comes out skilled in all 60 skills.” Clinical laboratories may want to explore creating similar programs with high schools in their own areas. (Photo copyright: Twitter.)

Dynamic Curriculum of Clinical Laboratory Skills

During the first year of the WEMOCO program, students learn skills that Jim Payne, a Medical Laboratory Assisting and Phlebotomy program instructor at WEMOCO, stated he learned in college. These include:

The students also learn the theories and techniques behind phlebotomy and how to perform blood draws (venipuncture).

Students spend 40 hours drawing blood samples from real patients in local medical laboratories and can earn a certification as a Phlebotomy Technician after completing the necessary coursework.

During the second year of the program, students learn college-level:

They also receive their certifications in American Red Cross CPR/AED and First Aid and spend 80 hours actually working in local clinical laboratories. Upon completion of the second year of coursework, students can earn a certification as a Certified Medical Laboratory Assistant.

“In both cases, they can get jobs straight out of the program,” said Payne in the CLP podcast. “But a lot of our grads go on to college for medical laboratory careers.”

Overcoming Vocational School Stigma

Recruiting students into the program was initially challenging as some of the negative stigma surrounding non-traditional coursework had to be overcome. Vocational education is now referred to as career and technical education and the WEMOCO program is more academically focused than previous vocational studies. Students can obtain some college credits when completing the two-year program.

“With my students, when we are teaching them how to do the math around making laboratory solutions, for example, that requires algebra,” Payne explained. “And they have to actually make something with the algebra and suddenly it starts to make a lot more sense than the way that they were taught in a traditional high school.”

In addition, some students interested in the program struggled in a typical high school environment due to lack of direction, according to Payne. However, when those same students found their focus, discovered a passion, and were motivated and challenged, they flourished. 

Originally, Payne gave a talk to potential enrollees. But he found there was more interest if students were given a hands-on experience at their first exposure to the program. He also lets current students interact with interested students and allows them to answer any questions in a student-friendly manner. 

“Students who are interested in the program come in, they get lab coats on, they get gloves on, and they are then told a story about a case and have to perform a few experiments to try to determine what is wrong with a patient. They actually do things,” Payne explained.

Multiple Career Paths in Clinical Laboratories upon Graduation

One advantage to completing the two-year WEMOCO program is that students can explore all the different careers in clinical laboratory medicine and are offered opportunities to work in medical laboratory situations. Phlebotomy students perform 40 hours of work in a blood lab with a goal of performing 50 successful sticks, although many students perform more than that.

“I have students who are under the age of 18 drawing blood on real patients with real samples with these companies’ trainers. It’s like they have been hired,” Payne said. The medical laboratory assistant work is broken up into increments of two hours a day over the course of several months.

Another benefit to the WEMOCO program is that students are prepared for a job right out of high school, which pleases both the students and the parents. Many graduates of the program go on to college to study different fields within the clinical laboratory profession.

Attracting Young Students to the Clinical Laboratory Profession

Payne believes it is important to get young kids interested in the medical laboratory profession in the lower grade levels. His suggestions for stoking that level of interest include:

  • Developing programs that are age-appropriate but contain medical laboratory concepts.
  • Outreach programs where clinicians talk to students in the lower grades to spark interest.
  • Outreach programs where kids can perform simple experiments like staining onions and seeing results.
  • Telling stories and explaining the roles labs play in helping patients.
  • Holding field trips where students visit local clinical laboratories and observe medical laboratory professionals.
  • Opportunities for students to shadow medical laboratory technicians so the kids can imagine themselves in the profession.
  • Participating in local activity day/career day events.

He also believes that clinical laboratory professionals should promote their field at every opportunity.

“The biggest thing is actively advocating for the profession. Any chance I get, I’m going out and trying to talk to anyone about the clinical laboratory. Try to have some statistics in your back pocket or other things that can be a good talking point and make a powerful statement to people,” Payne suggested.

Determining unique ways to garner interest in the medical laboratory profession is a crucial step in mitigating staffing shortages. Clinical laboratory leaders may want to participate in community outreach programs and serve as advocates for their profession.

Healthcare Experts See Links Between COVID-19 and RSV as Tripledemic Pressures Ease on Hospitals and Clinical Laboratories

Some medical experts suggest an ‘immunity gap’ related to COVID-19 mitigation measures, while others point to alternative theories

Surge in fall/winter SARS-CoV-2, influenza (flu), and respiratory syncytial virus (RSV) hospitalizations and ensuing clinical laboratory test referrals—dubbed by some public health experts as a “tripledemic”—appear to have eased in the US, according to stats from the US Centers for Disease Control and Prevention (CDC), Becker’s Hospital Review reported. However, scientists are still left with questions about why the RSV outbreak was so pronounced.

Some healthcare experts point to an “immunity gap” tied to the COVID-19 pandemic, while others suggest alternative theories such as temporary immunodeficiency brought on by COVID-19. In most cases, RSV causes “mild, cold-like symptoms,” but the CDC states it also can cause serious illness, especially for infants, young children, and older adults, leading to emergency room visits, hospitalizations, and an increased demand for clinical laboratory testing.

Pulmonology Advisor reported that the disease typically peaks between December and February, but hospitalizations this season hit their peak in November with numbers far higher than in previous years. In addition to infants and older adults, children between five and 17 years of age were “being hospitalized far in excess of their numbers in previous seasons,” the publication reported.

Asuncion Meijas MD, PhD

“Age by itself is a risk factor for more severe disease, meaning that the younger babies are usually the ones that are sick-sick,” pediatrician Asuncion Mejias, MD, PhD (above), a principal investigator with the Center for Vaccines and Immunity at Nationwide Children’s Hospital in Columbus, Ohio, told MarketWatch. Now, she added, “we are also seeing older kids, probably because they were not exposed to RSV the previous season.” Clinical laboratories in hospitals caught the brunt of those RSV inpatient admissions. (Photo copyright: Nationwide Children’s Hospital.)

Did COVID-19 Cause Immunity Gap and Surge in Respiratory Diseases?

CDC data shows that hospitalization rates linked to RSV have steadily declined since hitting their peak of 5.2 per 100,000 people in mid-November. In contrast, hospitalizations linked to the flu peaked in late November and early December at 8.7 per 100,000. Hospitalizations linked to COVID 19—which still exceed those of the other respiratory diseases—reached a plateau of 9.7 per 100,000 in early December, then saw an uptick later that month before declining in the early part of January, 2023, according to the CDC’s Respiratory Virus Hospitalization Surveillance Network (RESP-NET) dashboard.

Surveillance by the CDC’s National Center for Immunization and Respiratory Diseases (NCIRD) revealed a similar pattern: An early peak in weekly numbers for emergency room visits for RSV, followed by a spike for influenza and steadier numbers for COVID-19.

So, why was the RSV outbreak so severe?

Respiratory diseases tend to hit hardest in winter months when people are more likely to gather indoors. Beyond that, some experts have cited social distancing and masking requirements imposed in 2020 and 2021 to limit the spread of COVID 19. These measures, along with school closures, had the side effect of reducing exposure to influenza and RSV.

“It’s what’s being referred to as this ‘immunity gap’ that people have experienced from not having been exposed to our typical respiratory viruses for the last couple of years, combined with reintroduction to indoor gatherings, indoor venues, indoor school, and day care without any of the mitigation measures that we had in place for the last couple of years,” infectious disease expert Kristin Moffitt, MD, of Boston Children’s Hospital told NPR.

Term ‘Immunity Debt’ Sparks Controversy

Other experts have pushed back against the notion that pandemic-related public health measures are largely to blame for the RSV upsurge. Many have objected to the term “immunity debt,” a term Forbes reported on in November.

“Immunity debt is a made-up term that did not exist until last year,” pediatrician Dave Stukus, MD, wrote on Twitter. Stukus is a Professor of Clinical Pediatrics in the Division of Allergy and Immunology at Nationwide Children’s Hospital in Columbus, Ohio.

An article published by Texas Public Radio (TPR) suggests further grounds for skepticism, stating that “the immunity debt theory doesn’t seem to hold up to scrutiny.”

Pediatrician and infectious disease expert Theresa Barton, MD, of UT Health San Antonio noted that there was also a big RSV surge in summer of 2021.

“That was sort of the great unmasking, and everybody got viral illnesses,” she told TPR. “Now we’re past that. We’ve already been through that. We should have some immunity from that and we’re having it again.”

She added that “the hospital is filled with babies who are less than a year of age who have RSV infection. Those children weren’t locked down in 2020.”

The story also noted that not all Americans complied with social distancing or masking guidelines.

“We’re not seeing [less viral illness in] states in the United States that were less strict compared to states that were stricter during mask mandates and things like that. All the states are being impacted,” Barton told TPR.

Perfect Storm of Demand for Clinical Laboratory Testing

Barton suggested that COVID-19 might have compromised people’s immune systems in ways that made them more susceptible to other respiratory diseases. For example, a study published in Nature Immunology, titled, “Immunological Dysfunction Persists for Eight Months following Initial Mild-to-Moderate SARS-CoV-2 Infection,” found that some patients who survived COVID-19 infection developed post-acute long COVID (LC, aka, COVID syndrome) which lasted longer than 12 weeks. And that “patients with LC had highly activated innate immune cells, lacked naive T and naive B cells, and showed elevated expression of type I IFN (IFN-β) and type III IFN (IFN-λ1) that remained persistently high at eight months after infection.”  

Experts speaking to The Boston Globe said that multiple factors are likely to blame for the severity and early arrival of the RSV outbreak. Pediatric hospitalist and infectious disease specialist Chadi El Saleeby, MD, of Massachusetts General Hospital, said the severity of some cases might be tied to simultaneous infection with multiple viruses.

Clinical laboratories experienced a perfect storm of infectious disease testing demands during this tripledemic. Hopefully, with the arrival of spring and summer, that demand for lab tests will wane and allow for a return to a normal rate of traditional laboratory testing.
