Experts advise clinical laboratories to prepare now for a marked increase in demand for RSV, COVID-19, and influenza testing
Are the COVID-19 lockdowns responsible for the increase in cases of respiratory syncytial virus (RSV)? Some physicians believe that may be the case and it has hospitals, clinical laboratories, and pathology groups scrambling to prepare for a possible “tripledemic,” according to UC Davis Health.
The addition of RSV as we move into what is predicted to be a bad influenza (flu) season has prompted the Centers for Disease Control and Prevention (CDC) to issue a Health Alert Network (HAN) advisory which states, “Co-circulation of respiratory syncytial virus (RSV), influenza viruses, SARS-CoV-2, and others could place stress on healthcare systems this fall and winter.” This is especially true of clinical laboratories that still struggle to keep pace with demand for COVID-19 testing.
“COVID cases are expected to rise during the winter. This will be occurring at the same time we expect to see influenza rates increase while we are already seeing an early start to RSV season,” said Dean Blumberg, MD (above), chief of pediatric infectious diseases at UC Davis Children’s Hospital. “With all three viruses on the rise, we are worried about an increase in the rates of viral infection that may lead to an increase in hospitalizations.” Clinical laboratories should prepare for a marked increase in demand for RSV testing, as well as COVID-19 and influenza.

Masking, Lockdowns, and Social Distancing Could be Responsible
Every winter in the United States, outbreaks of the flu and RSV occur. However, this year the RSV outbreak appears to be more serious. The CDC warns that “surveillance has shown an increase in RSV detections and RSV-associated emergency department visits and hospitalizations in multiple US regions, with some regions nearing seasonal peak levels.”
The current spread of RSV infections taking place in the US varies from prior outbreaks in notable ways:
Incidents are happening in the fall, whereas RSV outbreaks usually peak starting in late December.
Older children as well as infants are being hospitalized.
Current cases appear to be more severe.
Episodes are rising at a time when pediatric hospitalizations are already higher than usual due to other illnesses like COVID-19, influenza, and biennial enteroviruses.
Some experts believe that masking and social distancing due to the COVID-19 pandemic resulted in a respite of RSV infections in 2020. However, cases intensified in 2021, most likely a result of fewer young children being exposed to RSV during the previous year.
Most children typically have had at least one RSV infection before the age of two and the illness becomes less troublesome as children get older.
“The theory is that everyone’s now back together and this is a rebound phenomenon,” Jeffrey Kline, MD, Associate Chair of Research, Wayne State University School of Medicine in Detroit, told MarketWatch. “If we think about the relative increase—ninefold increase—that’s not nothing, especially in the pediatric [emergency departments]. Holy mackerel.”
Most RSV Infected Children Require Hospitalization
Kline is in charge of a surveillance network that aggregates information regarding incidents of viral infections from 70 US hospitals. The data shows that more children are being hospitalized with COVID-19 than with RSV, but that 5% of children are testing positive for both illnesses. About 60% of children in that group require hospitalization.
According to the CDC, individuals with RSV will typically begin to experience symptoms within four to six days after getting infected. Symptoms of RSV, which tend to appear in stages, include:
Runny nose
Decrease in appetite
Coughing
Sneezing
Fever
Wheezing
“RSV causes a mild cold illness in most people. But it can be very dangerous for very young children and older adults. And young infants are usually the most at risk of hospitalizations in what physicians would call their first RSV season,” said Andrea Garcia, JD, Vice President, Medicine and Public Health, American Medical Association (AMA), in a November 2 AMA update on the current flu season.
“In a pre-pandemic year,” she added, “we would see 1% to 2% of babies younger than six months with an RSV infection maybe needing to be hospitalized. And virtually all children have gotten an RSV infection by the time they’re two-years-old.”
Infants are at a much higher risk of experiencing severe disease due to RSV because their immune systems are not fully developed, and those under six months old are unable to breathe through their mouths if they are congested.
Mejias is studying whether prior exposure to COVID-19 alters how a baby’s immune system reacts to RSV, and if it may lead to more severe illness in those babies.
“That is something to work on and understand,” she said.
Comorbidities and Compromised Immune Systems also a Factor
Older adults and adults with weakened immune systems are predisposed to RSV infections, but there are things people can do to mitigate their chances of becoming ill from RSV.
“[RSV] is spread through contact with droplets from the nose and throat of infected people when they cough or sneeze. It can also be spread through respiratory secretions on surfaces,” said Garcia in the AMA update. “So, it’s a really good idea to clean and disinfect surfaces, especially in areas where young children are constantly touching things. Handwashing is always important. And if you are sick, please stay home.”
She added, “Premature infants, children with certain medical conditions, are also eligible to take a monthly monoclonal antibody treatment during RSV season, and that can help them stay out of the hospital.”
Most RSV infections typically go away on their own within a week or two. But such infections can lead to more severe illnesses, such as bronchiolitis and pneumonia. The more serious cases may require hospitalization with additional oxygen, IV fluids, and even intubation with mechanical ventilation. In most cases, hospitalization only lasts a few days, according to the CDC.
Be Prepared for a Tripledemic
“Health officials are concerned that this could be a sign of what’s to come,” stated Garcia in the AMA update. “A difficult winter, with multiple respiratory viruses circulating.”
For clinical laboratory managers, the early arrival of RSV cases at the front end of this influenza season provides an opportunity to position their labs to better meet the demand for RSV testing. They should also advise their client physicians that there may be a surge of respiratory illnesses during this flu season.
Organizations representing clinical laboratories and other critical healthcare providers urged Congress to pass the Saving Access to Laboratory Services Act by January 1, 2023, to prevent deep cuts in reimbursements
Lessons about the essential role of clinical laboratories during a pandemic was the central theme in a significant publication released recently. The authors were the presidents of two of the nation’s largest healthcare companies and their goal was to connect the value clinical labs delivered during the COVID-19 pandemic to the financial threat labs face should the Protecting Access to Medicare Act of 2014 (PAMA) fee cuts coming to the Medicare Part B Clinical Laboratory Fee Schedule (CLFS) be implemented.
In an article for RealClearPolicy, healthcare executives William G. Morice II, MD, PhD (left), CEO/President, Mayo Clinic Laboratories, and Matt Sause (right), President of Roche Diagnostics North America wrote, “Without PAMA reform, labs could face drastically reduced reimbursement for commonly performed lab tests for a host of diseases.” (Photo copyrights: Mayo Clinic Laboratories/Roche Diagnostics.)
IVD Companies and Clinical Laboratories Sound Alarm
Morice and Sause warn that—without PAMA reform—the nation’s vital medical laboratories will face “drastically reduced reimbursement” for commonly performed lab tests for diseases, including diabetes, heart disease, and cancer. Reimbursement cuts may cause clinical labs serving “the most vulnerable and homebound” to reduce services or close, they noted.
“To emerge from nearly three years of a pandemic by sending the signal that austerity is our nation’s health policy when it comes to testing and diagnostics would be a significant mistake,” they wrote.
“If the proposed cuts to reimbursements for diagnostic tests are allowed to take effect, disparities caused by challenges with accessing diagnostic tests will likely grow even further,” the authors continued.
However, they added, “The Saving Access to Laboratory Services Act [SALSA] would reform PAMA to require accurate and representative data from all laboratory segments that serve Medicare beneficiaries to be collected to support a commonsense Medicare fee schedule that truly represents the market.”
How PAMA Affects Clinical Laboratory Reimbursements
PAMA, which became law in 2014, was aimed at marrying Medicare Part B Clinical Laboratory Fee Schedule (CLFS) reimbursement rates to rates medical laboratories receive from private payers, the National Independent Laboratory Association (NILA) explained in a news release.
But from the start, in its implementation of the PAMA statute, the methods used by the federal Centers for Medicare and Medicaid Services (CMS) to collect data on lab test prices paid by private payers—which were the basis for calculating new lab test prices for the Medicare program—were criticized by many laboratory professionals and other health experts.
Critics frequently pointed out that several types of clinical laboratories were excluded from reporting their private payer lab test prices. Thus, the data collected and used by CMS did not accurately represent the true range of prices paid for clinical lab tests by private health insurance plans, said lab industry groups.
CMS regulations “exclude most hospital outreach laboratories and physician office laboratories from data collection. This approach depresses median prices and has led to deep cuts to lab reimbursement. Many tests were cut up to 30% in 2018 when the new system went into effect,” the America Association for Clinical Chemistry (AACC) noted in a statement.
On September 8, just weeks after publication of the article authored by Morice and Sause, 26 organizations representing clinical laboratories and diagnostics manufacturers sent a letter to Congressional leaders. In it they described the financial impact on labs due to the current law’s omission of some outreach and physician office lab testing, and they urged the passage of the SALSA legislation.
“The significant under-sampling led to nearly $4 billion in cuts to those labs providing the most commonly ordered test services for Medicare beneficiaries,” the organizations wrote in their letter. “For context, the total CLFS spend for 2020 was only $8 billion.”
Reimbursement Cuts to Lab Tests are Coming if SASLA Not Passed
“Without Congressional action, beginning on Jan. 1, 2023, laboratories will face additional cuts of as much as 15% to some of the most commonly ordered laboratory tests,” the NILA said.
“Enactment of the Saving Access to Laboratory Services Act (SALSA/H.R. 8188/S.4449) is urgently needed this year, to allow laboratories to focus on providing timely, high quality clinical laboratory services for patients, continuing to innovate, and building the infrastructure necessary to protect the public health,” NILA added.
In an editorial she wrote for Clinical Lab Products, titled, “Be a Labvocate: Help Pass SALSA Legislation,” Kristina Martin, Clinical Pathology Operations Director, Department of Pathology, University of Michigan Medicine said, “The SALSA legislation provides a permanent, pragmatic approach to evaluating the CLFS, eliminating huge swings, either positive or negative as it pertains to Medicare reimbursement. It also allows for a more comprehensive evaluation of data to be collected from a broader sampling of laboratory sectors.”
Uses statistical sampling for widely available tests performed by a “representative pool of all clinical laboratory market segments.”
Introduces annual “guardrails” aimed at creating limits for reductions as well as increases in CLFS rates.
Excludes Medicaid managed care rates since they are not true “market rates.”
Gives labs the option to exclude mailed remittances from reporting if less than 10% of claims.
Eases clinical labs’ reporting requirements by changing data collection from three years to four.
Make Your Views Known
Proponents urge Congress to act on SALSA before the end of the year.

Goal is to demonstrate how whole human genome sequencing of newborns can deliver important diagnostic findings associated with 250 genetic conditions
Clinical laboratory testing and genetics are moving closer to the delivery room than ever before. In the largest study of its kind in North America, genomic scientists plan to supplement traditional screening for inherited diseases—traditionally performed on a blood sample taken shortly after birth—with whole genome sequencing (WGS) on 100,000 newborns in New York City during their first five years of life, LifeSciencesIntelligence reported.
Conducted by genetic scientists at NewYork-Presbyterian (NYP) and Columbia University, in collaboration with genetic company GeneDx, a wholly-owned subsidiary of health intelligence company Sema4 (NASDAQ:SMFR), the genetic research study, called GUARDIAN (Genomic Uniform-screening Against Rare Diseases In All Newborns), will screen newborn babies for 250 rare diseases that are generally not tested for.
The GUARDIAN program will “drive earlier diagnosis and treatment to improve the health of the babies who participate, generate evidence to support the expansion of newborn screening through genomic sequencing, and characterize the prevalence and natural history of rare genetic conditions,” according to a Sema4 news release.
“The appetite for this is growing. The awareness of this is growing. We all see it as inevitable,” medical geneticist Robert Green, MD, at Brigham and Women’s Hospital and Harvard Medical School told USA Today. “We are grossly underutilizing the life-saving benefits of genetics and we have to get past that.” Clinical laboratory leaders understand the value of early detection of disease and subsequent early treatment.

Improving Health of Babies Through Early Detection of Disease
GUARDIAN aims to use WGS to identify conditions at birth that can affect long-term health and subsequently enhance treatment options and possibly prevent disability or death.
The 250 different diseases GUARDIAN will be screening for typically strike young children. They are mostly rare conditions that:
have an onset before five years of age,
have a greater than 90% probability of the condition developing based on the genetic result,
have effective approaches and treatments that are already available, and/or
have a well-established natural history of the condition.
“We’re entering the therapeutic era and leaving the diagnostic era,” Paul Kruszka, MD, Chief Medical Officer at GeneDx told USA Today. “This potentially has the opportunity to change the way we practice medicine, especially in rare disease.”
Some Parents Reluctant to Agree to Genetic Testing
Green and his research team first began analyzing the genetic sequences of newborns back in 2013. They believe the costs of performing infant WGS is worthwhile because it can improve lives. However, Green also recognizes that some parents are reluctant to agree to this type of genetic testing due to concerns regarding privacy and the fear of discovering their baby may have an illness.
“You’ve gone through all this pregnancy and you’re sitting there with a healthy baby (and I’m) offering you the opportunity to find out something that’s devastating and terrifying,” he told USA Today. “How fun is that?”
Green continued. “We can respect people who don’t want to know, but also respect people who do want to know. Some families will say ‘I treasure the precious ignorance.’ Others will say ‘If I could have known, I would have poured my heart and soul into clinical trials or spent more time with the child when she was healthy.’”
WGS Screening Identifies Undiagnosed Illnesses in Newborn’s Family
The scientists also found that performing WGS in newborns can detect diseases in the infants as well as unknown illnesses in the families of those babies. According to Kruszka, many parents often seek a diagnosis for a rare disease present in their children for several years. Since many common diseases develop as a result of certain combinations of genes, if illnesses are diagnosed at birth, it could extradite the treatment process, prevent complications, and provide better health outcomes for patients.
“We are relentlessly focused on accelerating the adoption and use of genomic information to impact the lives of as many people as possible, particularly newborns and children,” said Katherine Stueland, President and CEO, Sema4, in the Sema4 news release. “As the first commercial laboratory to launch a rapid whole genome sequencing offering, to address broad unmet needs for early diagnosis, participation in this study is an important step forward for healthcare and in delivering on our goal to sequence once, analyze forever.”
The study is open to all babies in New York City who are born in a health system that participates in the GUARDIAN program, regardless of their race, income, or health insurance coverage.
“The results from this study will help us understand the true impact sequencing at birth can have on newborns and their families in comparison to the current standard of care, particularly as we’ll evaluate clinical outcomes in addition to the psychosocial effect on families,” said Kruszka in the Sema4 news release.
Anything that improves the health of newborn babies is a good thing. Regardless of the cost, if DNA analysis can give newborns and their families a better chance at detecting inherited diseases early while clinical laboratory treatment could make a difference, it is worth pursuing.
Experts cite high vaccination rates and behavioral changes among at-risk groups, but warn about complacency; clinical laboratories should remain vigilant
In July, Scott Gottlieb, MD, Commissioner of the US Food and Drug Administration (FDA) from May 2017 to April 2019, wrote an op-ed in The New York Times titled, “Monkeypox Is About to Become the Next Public Health Failure.” In it, he wrote, “Our country’s response to monkeypox has been plagued by the same shortcomings we had with COVID-19.” But has it improved? Clinical laboratory leaders and pathology group managers will find it informative to find out what has taken place since Gottlieb made his stark prediction.
The global monkeypox outbreak that emerged last spring appears to have subsided in the US and Europe, though it remains to be seen if the disease can be completely eradicated, according to multiple media reports. As of Oct. 26, 2022, the Centers for Disease Control and Prevention (CDC) reported a 7-day rolling average of 30 cases per day in the US, down from a peak of nearly 440/day in early August.
Cases are also down in cities that earlier reported heavy outbreaks. For example, the New York City Health Department reported a 7-day average of just two cases per day on Oct. 25, compared with 73/day on July 30.
And the San Francisco Department of Public Health announced on Oct. 20 that it would end the city’s public health emergency on monkeypox (MPX) effective on Oct. 31. “MPX cases have slowed to less than one case per day and more than 27,000 San Franciscans are now vaccinated against the virus,” the agency stated in a press release.
“Once again, we caution that a declining outbreak can be the most dangerous outbreak, because it can tempt us to think that the crisis is over and to let down our guard,” said World Health Organization (WHO) Director-General Tedros Adhanom Ghebreyesus, PhD, in an Oct. 12 global press briefing. “That’s not what WHO is doing. We are continuing to work with countries around the world to increase their testing capacity, and to monitor trends in the outbreak.” Clinical laboratories should not assume the outbreak has passed but continue to be vigilant and prepared for increased demand in monkeypox testing.

Changing Behavior Lowers Infection Rates
In addition to high vaccination rates, public health experts have attributed the decline to behavioral changes among at-risk groups. “There were really substantial changes among men who have sex [with] men,” infectious disease physician Shira Doron, MD, of Tufts Medical Center in Boston, told ABC News.
On September 2, the CDC published the results of a survey indicating that about half of men who have sex with men “reported reducing their number of sex partners, one-time sexual encounters, and use of dating apps because of the monkeypox outbreak.”
Another likely factor is the disease’s limited transmissibility. “Initially, there was a lot of concern that monkeypox could spread widely at daycares or in schools, but, overall, there has been very little spread among children,” NPR reported.
But citing multiple studies, the NPR story noted “that often there isn’t very much virus in the upper respiratory tract,” where it might spread through talking or coughing. “Instead, the highest levels of virus occur on sores found on the skin and inside the anus.”
These studies, along with earlier research, “explain why monkeypox is spreading almost exclusively through contact during sex, especially anal and oral sex, during the current outbreak,” NPR reported.
Monkeypox Could Mutate, experts say
Despite the promising numbers, public health experts are warning that monkeypox could remain as a long-term threat to public health. According to an article in Nature, “At best, the outbreak might fizzle out over the next few months or years. At worst, the virus could become endemic outside Africa by reaching new animal reservoirs, making it nearly impossible to eradicate.”
In addition to the limited transmissibility of the virus, Nature noted that the outbreak stems from a relatively mild form of the pathogen and is rarely fatal. As of Oct. 28, the CDC reported a total of just six confirmed deaths in the US out of a total of 28,302 confirmed cases since the first infections were reported in May.
It is possible that the virus could mutate into a more contagious form, but Nature noted that monkeypox is a DNA virus, and that they tend to mutate more slowly than RNA viruses such as SARS-CoV-2 and HIV. Nevertheless, University of Alabama at Birmingham School of Medicine bioinformatician Elliot Lefkowitz, PhD, warned that a “worrisome mutation” could arise if the outbreak continues for much longer.
“I have no confidence that all the people who need to be tested are being tested,” she told Nature. She expressed concerns that people could resume risky behavior if they think the danger has passed.
Another question is whether currently available vaccines offer long-lasting protection. And though reported case numbers are down in the US and Europe, they are rising in parts of Africa and South America, Nature noted.
Gottlieb’s Dire Prediction
The decline in new infections followed dire warnings last summer about the possible consequences of the outbreak. In his New York Times op-ed, former Gottlieb criticized the CDC for being slow to test for the virus. He wrote, “[I]f monkeypox gains a permanent foothold in the United States and becomes an endemic virus that joins our circulating repertoire of pathogens, it will be one of the worst public health failures in modern times not only because of the pain and peril of the disease but also because it was so avoidable.”
At the time of his writing, Gottlieb was right to be concerned. On July 29, the CDC reported a seven-day moving average of 390 reported cases per day. According to the federal agency, a reported case “Includes either the positive laboratory test report date, CDC call center reporting date, or case data entry date into CDC’s emergency response common operating platform, DCIPHER.”
Quashing the outbreak, Gottlieb estimated, would have required about 15,000 tests per week among people presenting symptoms resembling monkeypox. But between mid-May and the end of June, he noted, the CDC had tested only about 2,000 samples, according to the federal agency’s July 15 Morbidity and Mortality Weekly Report (MMWR).
As a remedy, Gottlieb called on the Biden administration to re-focus the CDC’s efforts more on disease control “by transferring some of its disease prevention work to other agencies,” including the FDA.
Regulators and lawmakers are considering proposed changes to CLIA and PAMA involving medical laboratory services
Clinical laboratories and pathology groups should monitor a series of federal regulatory developments underway this fall. The proposals and documents will potentially affect how lab managers and staff do their jobs and how much Medicare reimbursement medical laboratories receive for certain diagnostic tests next year.
Among the initiatives under consideration are the following:
Below are details about these laboratory-related federal bills and regulatory documents that observant laboratory managers will want to track in the coming months.
“Clinical laboratories need to make sure that they have proper requisitions and documentation for genetic testing that involves telemedicine.” Danielle Tangorre, JD (above), a partner at law firm Robinson and Cole LLP in Albany, NY, told Dark Daily. (Photo copyright: Robinson and Cole LLP.)
CLIA Fee Increases and Testing Personnel Changes
The federal Centers for Medicare and Medicaid Services (CMS) is examining fee and personnel changes for CLIA. Officials from CMS are reviewing public comments on the proposal ahead of publishing a final rule.
Among other changes, the proposal would:
Institute a 20% across-the-board increase on existing fees.
Establish a biennial increase of CLIA fees for follow-up surveys, substantiated complaint surveys, and revised certificates.
Add doctoral, master’s, and bachelor’s degrees in nursing to qualify testing personnel for high and moderate complexity testing.
“The Practitioner does not have sufficient contact with or information from the purported patient to meaningfully assess the medical necessity of the items or services ordered or prescribed.
“The Telemedicine Company compensates the Practitioner based on the volume of items or services ordered or prescribed, which may be characterized to the Practitioner as compensation based on the number of purported medical records that the Practitioner reviewed.
“The Telemedicine Company only furnishes items and services to Federal health care program beneficiaries and does not accept insurance from any other payor.
“The Telemedicine Company does not expect Practitioners (or another Practitioner) to follow up with purported patients nor does it provide Practitioners with the information required to follow up with purported patients (e.g., the Telemedicine Company does not require Practitioners to discuss genetic testing results with each purported patient).”
And more.
“In the telehealth space, the issue the OIG has flagged is that genetic tests are being ordered without patient interaction or with only brief telephonic conversations,” Danielle Tangorre, JD, a partner at law firm Robinson & Cole LLP in Albany, N.Y., told Dark Daily.
New Bill May Eliminate 2023 Medical Laboratory Payment Cuts Under PAMA
Medical labs and pathology groups face payment cuts of up to 15% for 800 lab tests on the Medicare Clinical Lab Fee Schedule (CLFS) on Jan. 1, 2023, as part of PAMA.
The bill proposes to move regulatory oversight of LDTs from CLIA to the federal Food and Drug Administration (FDA). Champions of the bill argue that FDA regulation is needed for in vitro clinical tests (IVCTs) because they are similar to medical devices and bring with them patient safety concerns.
The bill seemed ready for a Senate vote over the summer but stalled. On Sept. 30, Congress passed a short-term resolution to keep the federal government funded. During negotiation, the VALID Act was removed from the larger spending package, according to Boston law firm Ropes and Gray.
Expect discussion to renew in Congress about the VALID Act after the mid-term elections.
Clinical laboratory leaders and pathology group managers will want to closely monitor the progress of these four federal legislative and regulatory developments. Each of the possible actions described above would significantly change the status quo in the compliance requirements and reimbursement arrangements for both clinical laboratory testing and anatomic pathology services.
