Guidehouse Healthcare Experts Outline Six Ways COVID-19 Pandemic Is Accelerating Healthcare Transformation

Financial losses for hospitals and health systems due to cancelled procedures and coronavirus expenses will lead to changes in healthcare delivery, operations, and clinical laboratory test ordering

COVID-19 is reshaping how people work, shop, and go to school. Is healthcare the next target of the coronavirus-induced transformation? According to two experts, the COVID-19 pandemic is pushing hospitals and health systems toward a “fundamental and likely sustained transformation,” which means clinical laboratories must be prepared to adapt to new provider needs and customer demands.

In “Industry Voices—6 Ways the Pandemic Will Remake Health Systems,” published in Fierce Healthcare, authors David Burik, Partner, and Brian Fisher, Director, at Guidehouse (formerly Navigant Consulting and a “portfolio company of Veritas Capital”), stated that COVID-19 has wreaked havoc with the finances of America’s hospitals and healthcare systems.

Burik and Fisher called attention to the staggering $50 billion-per-month loss for hospitals and health systems that was first revealed in an American Hospital Association (AHA) report published in May. The AHA report estimated a $200 billion loss from March 1, 2020, to June 30, 2020, due to increased COVID-19 expenses and cancelled elective and non-elective surgeries.

Adding to the financial carnage is the expectation that patient volumes will be slow to return. In “Hospitals Forecast Declining Revenues and Elective Procedure Volumes, Telehealth Adoption Struggles Due to COVID-19,” Burik said, “Healthcare has largely been insulated from previous economic disruptions, with capital spending more acutely affected than operations. But this time may be different since the COVID-19 crisis started with a one-time significant impact on operations that is not fully covered by federal funding.

“Providers face a long-term decrease in commercial payment, coupled with a need to boost caregiver and consumer-facing digital engagement, all during the highest unemployment rate the US has seen since the Great Depression,” he continued. “For organizations in certain locations, it may seem like business as usual. For many others, these issues and greater competition will demand more significant, material change.”

A Guidehouse analysis of a Healthcare Financial Management Association (HFMA) survey, suggests one-in-three provider executives expect to end 2020 with revenues at 15% below pre-pandemic levels, while one-in-five of them anticipate a 30% or greater drop in revenues. Government aid, Guidehouse noted, is likely to cover COVID-19-related costs for only 11% of survey respondents.

“The figures illustrate how the virus has hurled American medicine into unparalleled volatility. No one knows how long patients will continue to avoid getting elective care or how state restrictions and climbing unemployment will affect their decision making once they have the option,” Burik and Fisher wrote. “All of which leaves one thing for certain: Healthcare’s delivery, operations, and competitive dynamics are poised to undergo a fundamental and likely sustained transformation.”

As a result, the two experts predict these pandemic-related changes to emerge:

  • Payer-Provider Complexity on the Rise; Patients Will Struggle. As the pandemic has shown, elective services are key revenues for hospitals and health systems. But the pandemic also will leave insured patients struggling with high deductibles, while the number of newly uninsured will grow. Furthermore, upholding of the hospital price transparency ruling will add an unwelcomed spotlight on healthcare pricing and provider margins.
  • Best-in-Class Technology Will Be a Necessity, Not a Luxury. COVID-19 has been a boon for telehealth and digital health usage, creating what is likely to be a permanent expansion of virtual healthcare delivery. But only one-third of executives surveyed say their organizations currently have the infrastructure to support such a shift, which means investments in speech recognition software, patient information pop-up screens, and other infrastructure to smooth workflows will be needed.

“Through all the uncertainty COVID-19 has presented, one thing hospitals and health systems can be certain of is their business models will not return to what they were pre-pandemic,” Guidehouse Partner Chuck Peck, MD (above), a former health system CEO, said in a statement. “A comprehensive consumer-facing digital strategy built around telehealth will be a requirement for providers. Moreover, shifting hardware and physical assets to the cloud, and use of robotic process automation, has proven to be successful in improving back-office operations in other industries. Providers will need to follow suit.” Clinical laboratories and anatomic pathology groups should track these developments and respond appropriately to meet the changing needs of the hospitals and physicians they serve with diagnostic testing services.

  • The Tech Giants Are Coming. Both major retailers and technology stalwarts, such as Amazon, Walmart, and Walgreens, are entering the healthcare space. In January, Dark Daily reported on Amazon’s roll out of Amazon Care, a 24/7 virtual clinic, for its Seattle-based employees. Amazon (NASDAQ:AMZN) is adding to a healthcare portfolio that includes online pharmacy PillPack and joint-venture Haven Healthcare. Meanwhile, Walmart is offering $25 teeth cleaning and $30 checkups at its new Health Centers. Dark Daily covered this in an e-briefing in May, which also covered a new partnership between Walgreens and VillageMD to open up to 700 primary care clinics in 30 US cities in the next five years.
  • Work Location Changes Mean Construction Cost Reductions. According to Guidehouse’s analysis of the HFMA COVID-19 survey, one-in-five executives expect some jobs to remain virtual post-pandemic, leading to permanent changes in the amount of real estate needed for healthcare delivery. The need for a smaller real estate footprint could reduce capital expenditures and costs for hospitals and healthcare systems in the long term.
  • Consolidation is Coming. COVID-19-induced financial pressures will quickly reveal winners and losers and force further consolidation in the healthcare industry. “Resilient” healthcare systems are likely to be those with a 6% to 8% operating margins, providing the financial cushion necessary to innovate and reimagine healthcare post-pandemic.
  • Policy Will Get More Thoughtful and Data-Driven. COVID-19 reopening plans will force policymakers to craft thoughtful, data-driven approaches that will necessitate engagement with health system leaders. Such collaborations will be important not only during this current crisis, but also will provide a blueprint for policy coordination during any future pandemic.

As Burik and Fisher point out, hospitals and healthcare systems emerged from previous economic downturns mostly unscathed. However, the COVID-19 pandemic has proven the exception, leaving providers and health systems facing long-term decreases in commercial payments, while facing increased spending to bolster caregiver- and consumer-facing engagement.

“While situations may differ by market, it’s clear that the pre-pandemic status quo won’t work for most hospitals or health systems,” they wrote.

The message for clinical laboratory managers and surgical pathologists is clear. Patients may be permanently changing their decision-making process when considering elective surgery and selecting a provider, which will alter provider test ordering and lab revenues. Independent clinical laboratories, as well as medical labs operated by hospitals and health systems, must be prepared for the financial stresses that are likely coming.

New Artificial Intelligence Algorithm Uses Routine Clinical Laboratory Tests to Identify Patients Likely Infected with COVID-19

At hospitals where results of molecular COVID-19 testing can take up to several days to return, this new method for identifying potentially infected patients could improve triage

Frustrated by shortages of essential COVID-19 tests and supplies—as well by lengthy coronavirus test turn-around times—researchers at Weill Cornell Medicine have created an Artificial Intelligence (AI) algorithm that can use routine clinical laboratory test data to determine if a patient is infected with SARS-CoV-2, the coronavirus that causes the COVID-19 disease.

This is an important development because the turn-around-time (TAT) for common lab tests is generally much shorter than COVID-19 molecular diagnostics—such as real-time reverse transcription polymerase chain reaction (RT-PCR), currently the most popular coronavirus test—and certainly serological (antibody) diagnostics, which require an infection incubation time of as much as 10-14 days before testing.

Some RT-PCR diagnostic tests for COVID-19, which detect viral RNA on nasopharyngeal swab specimens, can take up to several days to return depending on the test and on the lab’s location. But routine medical laboratory tests generally return much sooner, often within minutes or hours, making this a potential game-changer for triaging infected patients.

Machine Learning Brings AI to COVID-19 Diagnostics

Advances in the use of AI in healthcare have led to the development of machine-learning algorithms that are being utilized as diagnostic tools for anatomic pathology, radiology, and for specific complex diseases, such as cancer. The Weill Cornell scientists wanted to see if alternative lab test results could be used by an algorithmic model to identify people infected with the SARS-CoV-2 coronavirus.

Sarina Yang, MD, PhD
“When patients come to the [emergency department] and the doctor orders several panels of routine lab [tests] and also the [SARS-CoV-2] RT-PCR test, generally the routine test results come back in a couple of hours,” Sarina Yang, MD, PhD (above), one of the authors of the study, told Modern Healthcare. “So, we thought it could be useful to use the routine labs to predict whether the RT-PCR results would be positive or negative to improve the triage process.” Yang is an assistant professor in the Department of Pathology and Laboratory Medicine, and Assistant Director of the central laboratory and Director of the toxicology laboratory at Weill Cornell Medicine.

To perform the research, the team incorporated patients’ age, sex, and race, into a machine learning model that was based on results from 27 routine lab tests chosen from a total of 685 different tests ordered for the patients. The study included 3,356 patients who were tested for SARS-CoV-2 at New York-Presbyterian Hospital/Weill Cornell Medical Center between March 11 and April 29 of this year. The patients ranged in ages from 18 to 101 with the mean age being 56.4 years. Of those patients, 1,402 were RT-PCR positive and the remaining 1,954 were RT-PCR negative.  

Using a machine-learning technique known as a gradient-boosting decision tree, the algorithm identified SARS-CoV-2 infections with 76% sensitivity and 81% specificity. When looking at only emergency department (ED) patients, the model performed even better with 80% sensitivity and 83% specificity. ED patients comprised just over half (54%) of the patients used for the study. 

Weill Cornell Medicine Algorithm Could Lower False Negative Test Results

The algorithm also correctly identified patients who originally tested negative for COVID-19, but who tested positive for the coronavirus upon retesting within two days. According to the researchers, these results indicated their model could potentially decrease the amount of incorrect test results.

“We are thinking that those potentially false negative patients may demonstrate a different routine lab test profile that might be more similar to those that test positive,” Fei Wang, PhD, Assistant Professor of Healthcare Policy and Research at Weill Cornell Medicine and the study’s senior author, told Modern Healthcare. “So, it offers us a chance to capture those patients who are false negatives.”

The researchers validated their model by comparing the results with patients seen at New York Presbyterian Hospital/Lower Manhattan Hospital during the same time period. Among those patients, 496 were RT-PCR positive and 968 were negative and the algorithmic model performed with 74% specificity and 76% sensitivity. 

In their study, published in the Oxford Academic journal Clinical Chemistry, titled, “Routine Laboratory Blood Tests Predict SARS-CoV-2 Infection Using Machine Learning,” the Weill Cornell Medicine scientists concluded that their research illustrated the algorithm could:

  • preliminarily identify high-risk SARS-CoV-2 infected patients before RT-PCR results are available,
  • risk stratify patients in the ED,
  • select patients who need relatively urgent retesting if initial RT-PCR results are negative,
  • help isolate infected patients earlier, and
  • assist in the identification of SARS-CoV-2 infected patients in areas where RT-PCR testing is unavailable due to financial or supply constraints.

Early Results of Study Promising, But More Research is Needed

Wang noted that more research is needed on the algorithm and that he and his colleagues are currently working on ways to improve the model. They are hoping to test it with different conditions and geographies.

“Our model in the paper was built on data from when New York was at its COVID peak,” he told Modern Healthcare. “At that time, we were not doing wide PCR testing, and the patients who were getting tested were pretty sick.”

At the time of the study, the positivity rate for COVID-19 at New York-Presbyterian Hospital was in the 40% to 50% range. That was substantially higher than the current positivity rate, which is in the 2% to 3% range, Modern Healthcare reported.

“This model we built in a population in New York in a certain time period, so we can’t guarantee that it will work well universally,” Wang told Modern Healthcare.

It’s exciting to think that advances in software algorithms may one day make it possible to combine routine clinical laboratory testing and create diagnostics that identify diseases in ways the individual tests were not originally designed to do.

This study is an example that researchers in AI and informatics are working to bring new tools and diagnostic capabilities to clinical laboratories. Also, this is a demonstration of how a patient’s results from multiple other types of lab tests can by analyzed using AI and similar analytical algorithms to diagnose a health condition unrelated to the original reasons for performing those tests.

If this can be demonstrated with other diseases and health conditions, it would open up one more way that pathologists and clinical laboratory scientists can contribute to more accurate diagnoses and improved selection of the most appropriate therapies for individual patients.

February COVID-19 Superspreader Event in Boston Confirmed by Use of Genetic Sequencing as Next-Gen Sequencing Is Put to Novel Uses, including in Clinical Laboratories

Gene sequencing is enabling disease tracking in new ways that include retesting laboratory specimens from before the SARS-CoV-2 outbreak to determine when it arrived in the US

On February 26 of this year, nearly 200 executives and employees of neuroscience-biotechnology company Biogen gathered at the Boston Marriott Long Wharf hotel for their annual leadership conference. Unbeknownst to the attendees, by the end of the following day, dozens of them had been exposed to and become infected by SARS-CoV-2, the coronavirus that causes the COVID-19 illness.

Researchers now have hard evidence that attendees at this meeting returned to their communities and spread the infection. The findings of this study will be relevant to pathologists and clinical laboratory managers who are cooperating with health authorities in their communities to identify infected individuals and track the spread of the novel coronavirus.

This “superspreader” event has been closely investigated and has led to intriguing conclusions concerning the use of genetic sequencing to revealed vital information about the COVID-19 pandemic. Recent improvements in gene sequencing technology is giving scientists new ways to trace the spread of COVID-19 and other diseases, as well as a method for monitoring mutations and speeding research into various treatments and vaccines. 

Genetic Sequencing Traces an Outbreak

“With genetic data, a record of our poor decisions is being captured in a whole new way,” Bronwyn MacInnis, PhD, Director of Pathogen Genomic Surveillance at the Broad Institute of MIT and Harvard, told The Washington Post (WaPo) during its analysis of the COVID-19 superspreading event. MacInnis is one of many Broad Institute, Harvard, MIT, and state of Massachusetts scientists who co-authored a study that detailed the coronavirus’ spread across Boston, including from the Biogen conference.

Titled, “Phylogenetic Analysis of SARS-CoV-2 in the Boston Area Highlights the Role of Recurrent Importation and Superspreading Events,” the paper explains how the researchers “sequenced and analyzed 772 complete SARS-CoV-2 genomes from the region” in order to investigate how the virus was introduced and spread through the area. They traced a specific mutation in the virus—“a simple switch of two letters in the virus’ 30,000-character genetic code,” WaPo reported.

What they discovered is both surprising and enlightening. According to WaPo’s report, at least 35 new cases of the virus were linked directly to the Biogen conference, and the same strain was discovered in outbreaks in two homeless shelters in Boston, where 122 people were infected. The variant tracked by the Boston researchers was found in roughly 30% of the cases that have been sequenced in the state, as well as in Alaska, Senegal, and Luxembourg.

“The data reveal over 80 introductions into the Boston area, predominantly from elsewhere in the United States and Europe. We studied two superspreading events covered by the data, events that led to very different outcomes because of the timing and populations involved. One produced rapid spread in a vulnerable population but little onward transmission, while the other was a major contributor to sustained community transmission,” the researchers noted in their study abstract.

“The same two events differed significantly in the number of new mutations seen, raising the possibility that SARS-CoV-2 superspreading might encompass disparate transmission dynamics. Our results highlight the failure of measures to prevent importation into [Massachusetts] early in the outbreak, underscore the role of superspreading in amplifying an outbreak in a major urban area, and lay a foundation for contact tracing informed by genetic data,” they concluded.

Anthony Fauci, MD
Some experts think humankind may be entering a period of increased pandemics. In their report published in Cell, titled, “Emerging Pandemic Diseases: How We Got to COVID-19,” Anthony Fauci, MD (above) Director of the National Institute of Allergy and Infectious Diseases (NIAID), and David Morens, MD, a senior associate professor at Johns Hopkins School of Public Health and Senior Advisor to Fauci, wrote, “One can conclude from this recent experience that we have entered a pandemic era. The causes of this new and dangerous situation are multifaceted, complex, and deserving of serious examination.” (Photo copyright: NIAID.)

Genetic Sequencing and Mutation Tracking

The use of genetic sequencing to trace the virus could inform measures to control the spread in new ways, but currently, only about 0.33% of cases in the United States are being sequenced, MacInnis told WaPo, and that not sequencing samples is “throwing away the crown jewels of what you really want to know.”

Another role that genetic sequencing is playing in this pandemic is in tracking viral mutations. One of the ways that pandemics worsen is when viruses mutate to become deadlier or more easily spread. Scientists are using genetic sequencing to monitor SARS-CoV-2 for such mutations.

A group of scientists at Texas A&M University led by Yue Xing, PhD, published a paper titled, “MicroGMT: A Mutation Tracker for SARS-CoV-2 and Other Microbial Genome Sequences,” which explains that “Although most mutations are expected to be selectively neural, it is important to monitor if SARS-CoV-2 will eventually evolve to be a stronger or weaker infectious agent as time goes on. Therefore, it is vital to track mutations from newly sequenced SARS-CoV-2 genome.”

Another group of researchers have identified such a mutation. “A SARS-CoV-2 variant carrying the Spike protein amino acid change D614G has become the most prevalent form in the global pandemic. Dynamic tracking of variant frequencies revealed a recurrent pattern of G614 increase at multiple geographic levels: national, regional, and municipal,” Bette Korber, PhD and her colleagues wrote in “Tracking Changes in SARS-CoV-2 Spike: Evidence That D614G Increases Infectivity of the COVID-19 Virus,” published in Cell. Korber is a Laboratory Fellow at Los Alamos National Laboratory and visiting faculty at Santa Fe Institute.

Korber’s findings are important because the mutation the scientists identified appears to have a fitness advantage. “Our data show that, over the course of one month, the variant carrying the D614G Spike mutation became the globally dominant form of SARS-CoV-2,” they wrote. Additionally, the study noted, people infected with the mutated variant appear to have a higher viral load in their upper respiratory tracts.

Genetic Sequencing, the Race for Treatments, Vaccines, and Managing Future Pandemics

A vaccine is the best hope for stopping a pandemic, but short of a vaccine, an effective clinical laboratory treatment is the next best thing. And as Dark Daily reported in “Advances in Gene Sequencing Technology Enable Scientists to Respond to the Novel Coronavirus Outbreak in Record Time with Medical Lab Tests, Therapies,” genetic sequencing is quickly becoming a critical tool to develop both.

If, as Fauci and Morens predict, future pandemics are likely, improvements in gene sequencing and analysis will become even more important for tracing, monitoring, and suppressing outbreaks. Clinical laboratory managers will want to watch this closely, as medical labs that process genetic sequencing will, no doubt, be part of that operation.

UCSF and Stanford Researchers Investigate Why Some Infected with COVID-19 Are Asymptomatic, While Others Become Severely Ill or Die

Might clinical laboratories soon be called on to conduct mass testing to find people who show little or no symptoms even though they are infected with the coronavirus?    

Clinical laboratory managers understand that as demand for COVID-19 testing exceeds supplies, what testing is done is generally performed on symptomatic patients. And yet, it is the asymptomatic individuals—those who are shown to be infected with the SARS-CoV-2 coronavirus, but who experience no symptoms of the illness—who may hold the key to creating effective treatments and vaccinations.

So, as the COVID-19 pandemic persists, scientists are asking why some people who are infected remain asymptomatic, while others die. Why do some patients get severely ill and others do not? Researchers at the University of California San Francisco (UCSF) and Stanford University School of Medicine (Stanford Medicine) are attempting to answer these questions as they investigate viral transmission, masking, immunity, and more.

And pressure is increasing on researchers to find the answer. According to Monica Gandhi, MD, MPH, an infectious disease specialist and Professor of Medicine at UCSF, millions of people may be asymptomatic and unknowingly spreading the virus. Gandhi is also Associate Division Chief (Clinical Operations/Education) of the Division of HIV, Infectious Diseases, and Global Medicine at UCSF’s Zuckerberg San Francisco General Hospital and Trauma Center.

“If we did a mass testing campaign on 300 million Americans right now, I think the rate of asymptomatic infection would be somewhere between 50% and 80% of cases,” she told UCSF Magazine.

On a smaller scale, her statement was borne out. In a study conducted in San Francisco’s Mission District during the first six weeks of the city’s shelter-in-place order, UCSF researchers conducted SARS-CoV-2 reverse transcription-PCR and antibody (Abbott ARCHITECT IgG) testing on 3,000 people. Approximately 53% tested positive for COVID-19 but had no symptoms such as fever, cough, and muscle aches, according to data reported by Carina Marquez, MD, UCSF Assistant Professor of Medicine and co-author of the study, in The Mercury News.

While their study undergoes peer-review, the researchers published their findings on the preprint server medRxiv, titled, “SARS-CoV-2 Community Transmission During Shelter-in-Place in San Francisco.”

Pandemic Control’s Biggest Challenge: Asymptomatic People

In an editorial in the New England Journal of Medicine (NEJM), Gandhi wrote that transmission of the virus by asymptomatic people is the “Achilles heel of COVID-19 pandemic control.”

In her article, Gandhi compared SARS-CoV-2, the coronavirus that causes COVID-19, to SARS-CoV-1, the coronavirus that caused the 2003 SARS epidemic. One difference lies in how the virus sheds. In the case of SARS-CoV-2, that takes place in the upper respiratory tract, but with SARS-CoV-1, it takes place in the lower tract. In the latter, symptoms are more likely to be detected, Gandhi explained. Thus, asymptomatic carriers of the coronavirus may go undetected.

Viral loads with SARS-CoV-1, which are associated with symptom onset, peak a median of five days later than viral loads with SARS-CoV-2, which makes symptom-based detection of infection more effective in the case of SARS-CoV-1,” Gandhi wrote. “With influenza, persons with asymptomatic disease generally have lower quantitative viral loads in secretions from the upper respiratory tract than from the lower respiratory tract and a shorter duration of viral shedding than persons with symptoms, which decreases the risk of transmission from paucisymptomatic persons.”

Absolutely nothing,” he told Mercury News. (Photo copyright: The Mercury News.)

Stanford Studies Immune Responses in COVID-19 Patients

Meanwhile, scientists at the Stanford University School of Medicine were on their own quest to find out why COVID-19 causes severe disease in some people and mild symptoms in others.

“One of the great mysteries of COVID-19 infections has been that some people develop severe disease, while others seem to recover quickly. Now, we have some insight into why that happens,” Bali Pulendran, PhD, Stanford Professor of Pathology, Microbiology, and Immunology and Senior Author of the study in a Stanford Medicine news release.

The study, published in Science, titled, “Systems Biological Assessment of Immunity to Mild Versus Severe COVID-19 Infection in Humans,” was based on analysis of 76 patients with COVID-19 and 69 healthy people from Hong Kong and Atlanta. The researchers pointed to flailing immune systems and “three molecular suspects” in the blood of COVID-19 patients they studied.

The Stanford research suggested that three molecules—EN-RAGE, TNFSF14, and oncostatin-M—“correlated with disease and increased bacterial products in human plasma” of COVID-19 patients. 

“Our multiplex analysis of plasma cytokines revealed enhanced levels of several proinflammatory cytokines and a strong association of the inflammatory mediators EN-RAGE, TNFSF14, and OSM with clinical severity of the disease,” the scientists wrote in Science.

Pulendran hypothesized that the molecules originated in patients’ lungs, which was the infection site. 

“These findings reveal how the immune system goes awry during coronavirus infections, leading to severe disease and point to potential therapeutic targets,” Pulendran said in the news release, adding, “These three molecules and their receptors could represent attractive therapeutic targets in combating COVID-19.”

Clinical Laboratories May Do More Testing of Asymptomatic People

The research continues. In a televised news conference, President Trump said COVID-19 testing plays an important role in “preventing transmission of the virus.” Clearly this is true and learning why some people who are infected experience little or no symptoms may be key to defeating COVID-19.

Thus, as the nation reopens, clinical laboratories may want to find ways to offer COVID-19 testing beyond hospitalized symptomatic patients and people who show up at independent labs with doctors’ orders. As supplies permit, laboratory managers may want to partner with providers in their communities to identify people who are asymptomatic and appear to be well, but who may be transmitting the coronavirus.

US Government Purchases 150 Million COVID-19 Antigen Tests from Abbott Laboratories for $760 Million; Only CLIA-Certified Clinical Laboratories Can Do Testing

Abbott sends the SARS-CoV-2 test results directly to patients’ smartphones, which can be displayed to gain entrance into areas requiring proof of COVID-19 testing

There is no greater example that COVID-19 is a major force for change in the clinical laboratory industry than the fact that—though the US federal government pays 50% of the nation’s total annual healthcare spend of $3.5 trillion—it recently spent $760 million to purchase 150 million COVID-19 tests from Abbott Laboratories (NYSE:ABT), an American multinational medical devices and healthcare company headquartered in Abbott Park, Ill., “to expand strategic, evidence-based testing in the United States,” according to the company’s website.

In August, the federal Food and Drug Administration (FDA) granted an emergency use authorization (EUA) to Abbott for its BinaxNOW portable rapid-response COVID-19 antigen (Ag) test. The credit-card sized test costs $5 and can return clinical laboratory test results in minutes, rather than hours, days, or in some cases, weeks, the Wall Street Journal (WSJ) reported.

The test includes a free smartphone app called NAVICA, which enables those tested to receive their test results directly on their mobile devices—bypassing the patient’s primary care physicians.

According to Abbott’s website, the app “allows people who test negative to get an encrypted temporary digital NAVICA Pass, similar to an airline boarding pass. NAVICA-enabled organizations will be able to verify an individual’s negative COVID-19 test results by scanning the individual’s digital NAVICA Pass to facilitate entry into facilities.”

This feature of Abbott’s new COVID-19 test is a good example of how quickly innovation in the medical laboratory testing profession is bringing new features and new capabilities to the marketplace. By marrying the SARS-CoV-2 test with the NAVICA Pass feature, Abbott hopes to deliver increased value—not just to physicians and their patients—but also to employers with employee screening programs and federal government programs designed to screen federal employees, as well as being used for screening travelers at airports and other transportation hubs.

Abbott appears to be banking that in the future such identification will be required to “enter organizations and other places where people gather,” as the company’s website states.

Testing Limited to CLIA-Certified Clinical Laboratories

An HHS news release announcing the government’s planned distribution of the BinaxNOW tests stated that “Testing will be potentially deployed to schools and to assist with serving other special needs populations.”

In the news release, Alex Azar, HHS Secretary, said, “By strategically distributing 150 million of these tests to where they’re needed most, we can track the virus like never before and protect millions of Americans at risk in especially vulnerable situations.”

The EUA adds that “Testing of nasal swab specimens using [BinaxNOW] … is limited to laboratories certified under CLIA that meet the requirements to perform high, moderate, or waived complexity tests. This test is authorized for use at the [point of care], i.e., in patient care settings operating under a CLIA Certificate of Waiver, Certificate of Compliance, or Certificate of Accreditation.”

The FDA’s EUA describes the BinaxNOW portable rapid-response COVID-19 antigen test (above) as “a lateral flow immunoassay intended for the qualitative detection of nucleocapsid protein antigen from SARS-CoV-2 in direct nasal swabs from individuals suspected of COVID-19 by their healthcare provider within the first seven days of symptom onset.” The test costs $5 and Abbott sends results directly to the patient’s smartphone using the free NAVICA app included with the test.

IVD Companies See Boom in COVID-19 Test Sales

Demand for COVID-19 testing has created opportunities for in vitro diagnostics (IVD) companies that can develop and bring tests to market quickly. 

Recent issues of Dark Daily’s sister print publication—The Dark Report (TDR)—covered IVD companies’ second quarter (Q2) boom in sales of COVID-19 instruments and tests, while also noting a fall-off in routine clinical laboratory testing during the COVID-19 pandemic. 

Abbott Laboratories saw molecular diagnostics sales increase 241% in Q2 driven by $283 million in sales of COVID-19 testing, while rapid diagnostic COVID-19 testing rose 11% on $180 million in sales in Q2, TDR reported, based on Abbott data.

“There is huge economic incentive for diagnostic companies to develop technologies that can be used to create rapid tests that are cheap to perform,” said Robert Michel, Publisher and Editor-in-Chief of TDR and Dark Daily. “In this sense, COVID is a major force for change.”

“This new COVID-19 antigen test is an important addition to available tests because the results can be read in minutes, right off the testing card,” said Jeff Shuren, MD, JD (above), Director of the FDA’s Center for Devices and Radiological Health (CDRH), in an FDA news release announcing the federal government’s $760 million purchase of 150 million Abbott BinaxNOW rapid-response antigen COVID-19 tests. “This means people will know if they have the virus in almost real-time. Due to its simpler design and the large number of tests the company anticipates making in the coming months, this new antigen test is an important advancement in our fight against the pandemic.” (Photo copyright: The New York Times.)

Abbott Invests in Proving BinaxNOW’s Capabilities

Abbott has a lot riding on the BinaxNOW test. Its portable, rapid molecular ID NOW COVID-19 test was touted by President Trump during a White House press briefing in March as “a whole new ballgame.” But then, researchers at New York University (NYU) published study data that questioned the accuracy and reliability of the test, which Dark Daily covered in “Abbott Labs’ ID NOW COVID-19 Rapid Molecular Test Continues to Face Scrutiny Over False Negatives.”

Thus, Abbott is determined to ensure this product launch is successful and that the test works as promised. According to a news release, “In data submitted to the FDA from a clinical study conducted by Abbott with several leading US research universities, the BinaxNOW COVID-19 Ag Card demonstrated sensitivity of 97.1% (positive percent agreement) and specificity of 98.5% (negative percent agreement) in patients suspected of COVID-19 by their healthcare provider within the first seven days of symptom onset.”

“The massive scale of this test and app will allow tens of millions of people to have access to rapid and reliable testing,” said Joseph Petrosino, PhD, professor and chairman, Molecular Virology and Microbiology, Baylor College of Medicine, in the Abbott news release. “With lab-based tests, you get excellent sensitivity but might have to wait days or longer to get the results. With a rapid antigen test, you get a result right away, getting infectious people off the streets and into quarantine so they don’t spread the virus.”

Abbott has invested hundreds of millions of dollars in two manufacturing facilities where the tests will be made, John Hackett Jr, PhD, an immunologist and Abbott’s Divisional Vice President Applied Research and Technology, and lead scientist on the BinaxNOW project, told The Atlantic.

“Our nation’s frontline healthcare workers and clinical laboratory personnel have been under siege since the onset of this pandemic,” said Charles Chiu, MD, PhD, professor of Laboratory Medicine at University of California, San Francisco, in the Abbott news release. “The availability of rapid testing for COVID-19 will help support overburdened laboratories, accelerate turnaround times, and greatly expand access to people who need it.”

However, other experts are not so sure. In the Atlantic article, Michael Mina MD, PhD, Assistant Professor Epidemiology at Harvard’s T.H. Chan School of Public Health, voiced the need to test both asymptomatic and pre-symptomatic people. “This is the type of [COVID-19] test we have been waiting for—but may not be the test.”

Nevertheless, the federal government’s investment is significant. Abbott plans to start shipping tens of millions of tests in September and produce 50 million tests per month starting in October, Forbes reported.

Shifting Clinical Laboratory Paradigms

BinaxNOW will be performed without doctors’ orders, in a variety of locations, and results go directly to patients’ smartphone—without a pathologist’s interpretation and medical laboratory report. This is new ground and the impact on non-CLIA labs, and on healthcare in general, is yet to be seen.

Clinical laboratory managers will want to monitor the rise of rapid-response tests that can be easily accessed, conducted, and reported on without physician input.
