Walmart, Quest Diagnostics, and DroneUp Collaborate on Pilot Project to Deliver COVID-19 Laboratory Tests to Consumers in Select Cities

Coronavirus pandemic expected to spur wider acceptance of drone delivery services for clinical laboratory specimens and medical supplies

Routine delivery of clinical laboratory specimens and medical supplies by drone moved one step closer to reality with news that Walmart (NYSE:WMT), Quest Diagnostics (NYSE:DGX), and DroneUp of Virginia Beach, Va., are partnering to bring at-home self-collection COVID-19 test kits to residents of several areas hard hit by the COVID-19 pandemic.

In its race to keep pace with online retailer Amazon (NASDAQ:AMZN), Walmart last September implemented two drone-delivery trials. One, according to Progressive Grocer, is with Tel Aviv, Israel-based drone company Flytrex, to deliver select grocery and household essentials in and around Fayetteville, N.C. The other trial program is with drone company Zipline of San Francisco, to test delivery of certain health and wellness products to areas around Walmart’s headquarters in Bentonville, Ark., Progressive Grocer also reported.

Then, Walmart announced a third pilot project for home delivery—one that could potentially affect clinical laboratories. This time, in collaboration with Quest and DroneUp, Walmart is piloting delivery of at-home COVID-19 collection kits in North Las Vegas, and Cheektowaga, New York, a Walmart news release stated.

Is this yet another example of how the COVID-19 pandemic will continue to drive shifts in delivery of key healthcare services? Probably.

According to Walmart’s news release, “Patients who qualify for drone delivery of the COVID-19 self-collection kits must live in a single-family residence within a 1-mile radius of the designated [Walmart] Supercenters in North Las Vegas and Cheektowaga. The kits will land on the driveway, front sidewalk, or backyard of the customer’s home, depending on where there are cars and trees. There is no delivery or kit cost for customers electing to receive an at-home [COVID-19] kit delivered via drone. Once the kits are delivered, the person will perform a self-administered nasal swab in the privacy of their home and send their sample back to Quest Diagnostics for testing using the included prepaid shipping label.”

The giant retailer’s expanding use of drone delivery systems will likely lead to greater acceptance among consumers of unmanned aerial vehicles for delivering all sorts of personal items, as well as various types of clinical laboratory specimens. If consumers embrace drone delivery systems, clinical laboratories with existing courier and logistics networks may experience another disruption in how they do business.

In a news release following the announcement of a yet another drone-delivery service of COVID-19 at-home test kits—this time in El Paso, Texas,—Amanda Jenkins, Vice President of Operation Support and Implementation, Walmart US Health and Wellness, said, “Walmart has been serving the El Paso community throughout the pandemic with drive-thru testing sites and extended testing hours, and we wanted to provide another way to access testing that provides convenience and leverages technology, while learning how drones could impact the delivery of healthcare in the future,” KTSM-9 TV reported.

Drone Delivery Systems Worldwide for Healthcare

The United States is not the only country turning to drone technology to speed deliveries and reduce person-to-person contact during the pandemic. A World Economic Forum blog post outlined the critical role drones are playing in China, the world’s most populated country, as it responds to the health crisis.

“At the moment of life and death, the air transport network can significantly confine the flow of people, avoid unnecessary physical contact, and prevent secondary transmission,” Lv Yinxiang, Secretary of the Party Committee of the County People’s Hospital, said in the blog post. “Medical samples delivered through air can shrink the delivery time … while saving precious field resources.”

Amazon also is predicting a bright future for drone delivery of all types of goods. In August, Amazon’s Prime Air drone delivery service received approval from the Federal Aviation Administration (FAA) to operate its fleet of drones, CNBC reported. Amazon launched its drone project in 2013 and began the process of seeking FAA approval in 2019.

In “UPS Expands Drone Delivery Service for Transporting Clinical Laboratory Specimens Across Healthcare Systems to Include Delivering Prescriptions from CVS Pharmacy to Customers’ Homes,” Dark Daily reported on UPS’ plans to become a major player in healthcare’s use of drones by partnering with CVS Health to not only transport clinical laboratory specimens, but also make pharmacy deliveries to customers’ homes.

And in “WakeMed Uses Drone to Deliver Patient Specimens,” Dark Daily’s sister publication, The Dark Report (TDR), reported on UPS’ launch of a drone delivery service on the WakeMed Health and Hospitals medical campus in Raleigh, N.C. The implementation followed a two-year test period during which UPS used drones manufactured by Matternet of Menlo Park, Calif., to fly clinical laboratory specimens from a medical complex of physicians’ offices to the health system’s clinical laboratory.

COVID-19 Pandemic Drives Drone Delivery System Development

Tom Ward, Walmart’s Senior Vice President for Customer Product, predicts the drone delivery systems being rolled out during the COVID-19 pandemic will increase the use of contactless delivery for all types of deliveries, not just healthcare.

“There’s a lot we can learn from our drone delivery pilots to help determine what roles drones can play in pandemic response, healthcare delivery, and retail,” he said in the Walmart news release. “We hope drone delivery of self-collection kits will shape contactless testing capabilities on a larger scale and continue to bolster the innovative ways Walmart plans to use drone delivery in the future.”

The widespread use of drone technology appears to be soaring to new heights as the COVID-19 pandemic moves forward into the new year. Clinical laboratory managers will want to keep their eyes on the skies as this new delivery system becomes more commonplace and potentially disrupts the way laboratory specimens traditionally have traveled to and from medical laboratories.

C₂N Diagnostics Releases PrecivityAD, the First Clinical Laboratory Blood Test for Alzheimer’s Disease

The St. Louis-based in vitro diagnostics (IVD) developer is making PrecivityAD available to physicians while awaiting FDA clearance for the non-invasive test

Clinical laboratories have long awaited a test for Alzheimer’s disease and the wait may soon be over. The first blood test to aid physicians and clinical laboratories in the diagnosis of patients with memory and cognitive issues has been released by C₂N Diagnostics of St. Louis. The test measures biomarkers associated with amyloid plaques in the brain—the pathological hallmark of Alzheimer’s.

C₂N Diagnostics was cofounded by David Holtzman, MD, and Randall Bateman, MD, of Washington University School of Medicine in St. Louis. They headed research that led to the PrecivityAD test and are included on a patent the university licensed to C₂N.

In a news release, PrecivityAD describes the laboratory-developed test (LDT) as “a highly sensitive blood test using mass spectrometry and is performed in C₂N’s CLIA-certified laboratory. While the test by itself cannot diagnose Alzheimer’s disease … the test is an important new tool for physicians to aid in the evaluation process.”

PrecivityAD provides physicians with an Amyloid Probability Score (APS) for each patient. For example:

  • A low APS (0-36) is consistent with a negative amyloid PET scan result and, thus, has a low likelihood of amyloid plaques, an indication other causes of cognitive symptoms should be investigated.
  • An intermediate APS (37-57) does not distinguish between the presence or absence of amyloid plaques and indicates further diagnostic evaluation may be needed to assess the underlying cause(s) for the patient’s cognitive symptoms.
  • A high APS (58-100) is consistent with a positive amyloid positron-emission tomography (PET) scan result and, thus, a high likelihood of amyloid plaques. Presence of amyloid plaques is consistent with an Alzheimer’s disease diagnosis in someone who has cognitive decline, but alone is insufficient for a final diagnosis.

The $1,250 test is not currently covered by health insurance or Medicare. However, C₂N Diagnostics has pledged to offer discounts to patients based on income levels.

Jeff Cummings, MD, ScD
Jeff Cummings, MD, ScD (above) Research Professor, Department of Brain Health, University of Nevada, Las Vegas, said in a C₂N Diagnostics press release, “A blood test for Alzheimer’s is a game changer.” While there is no cure for Alzheimer’s, a non-invasive blood test can help providers diagnose patients when their symptoms are mild and often misdiagnosed. “Advances in Alzheimer’s diagnostics are key to more effective identification, diagnosis, and clinical trial recruitment,” he added. Currently, brain changes caused by the disease are most commonly identified through PET scans. (Photo copyright: University of Nevada Las Vegas.)

Additional Research Requested

While C₂N’s PrecivityAD is the first test of its kind to reach the commercial market, it has not received US Food and Drug Administration (FDA) clearance, nor has the company published detailed data on the test’s accuracy. However, the PrecivityAD website says the laboratory-developed test “correctly identified brain amyloid plaque status (as determined by quantitative PET scans) in 86%” of 686 patients, all of whom were older than 60 years of age with subjective cognitive impairment or dementia.

But some Alzheimer’s advocacy groups are tempering their enthusiasm about the breakthrough. Eliezer Masliah, MD, Director of the Division of Neuroscience, National Institute on Aging, told the Associated Press (AP), “I would be cautious about interpreting any of these things,” he said of the company’s claims. “We’re encouraged, we’re interested, we’re funding this work, but we want to see results.”

Heather Snyder, PhD, Vice President, Medical and Scientific Relations at the Alzheimer’s Association told the AP her organization will not endorse a test without FDA clearance. The Alzheimer’s Association also would like to see the test studied in larger and diverse populations. “It’s not quite clear how accurate or generalizable the results are,” she said.

Braunstein defended the decision to make the test for Alzheimer’s immediately available to physicians, asking in the AP article, “Should we be holding that technology back when it could have a big impact on patient care?”

C₂N CEO Joel Braunstein, MD, told the AP C₂N Diagnostics will seek FDA clearance for PrecivityAD and publish study results. Earlier this month, PrecivityAD received CE marking from the European Union, as well as approval for its clinical laboratory to conduct tests for California patients, making it available in 46 states, the District of Columbia, and Puerto Rico, a press release noted.

ADDF Supports C2N’s Alzheimer’s Diagnostic Test

Howard Fillit, MD, Founding Executive Director and Chief Science Officer of the Alzheimer’s Drug Discovery Foundation (ADDF), maintains the first-of-its-kind blood test is an important milestone in Alzheimer’s research. ADDF invested in C₂N’s development of the test.

“Investing in biomarker research has been a core goal for the ADDF because having reliable, accessible, and affordable biomarkers for Alzheimer’s diagnosis is step one in finding drugs to prevent, slow, and even cure the disease,” Fillit said in an ADDF news release.

C₂N is also developing a Brain Health Panel to detect multiple blood-based markers for Alzheimer’s disease that will aid in better disease staging, treatment monitoring, and differential diagnosis.

Second Alzheimer’s Test in Development

Soon medical laboratories may have two different in vitro diagnostic tests for Alzheimer’s disease. On December 2, Fujirebio Diagnostics filed for FDA 510(k) premarket clearance for its Lumipulse G β-Amyloid Ratio (1-42/1-40) test, which looks for biomarkers found in cerebral spinal fluid.

The FDA granted the test Breakthrough Device Designation in February 2019, which may shorten the timeline to approval. The test utilizes Fujirebio’s Lumipulse G1200 instrument system.

“Accurate and earlier intervention will also facilitate the development of new drug therapies, which are urgently needed as the prevalence of Alzheimer’s disease increases with a rapidly aging population globally,” Fujirebio Diagnostics President and CEO Monte Wiltse said in a news release.

The Lumipulse G β-Amyloid test, which is intended for use in patients aged 50 and over presenting with cognitive impairment, has received CE-marking for use in the European Union.

Clinical laboratory managers will want to keep a close eye on rapidly evolving developments in testing for Alzheimer’s disease. It is the sixth leading cause of death in the United States and any clinical laboratory test that could produce an early and accurate diagnosis of Alzheimer’s Disease would become a valuable tool for physicians who treat patients with the symptoms of Alzheimer’s.

Reporter Who Broke Theranos Scandal Maintains Disgraced Clinical Laboratory Testing Company Could Have Returned Funds to Defrauded Investors Instead of Fighting Lawsuits

Former CEO Elizabeth Holmes now awaits March 9 court date on federal fraud charges that include reporting false medical laboratory test results on some patients

Clinical laboratory leaders have watched with keen interest the federal criminal proceedings against disgraced Theranos founder and former CEO Elizabeth Holmes, whose blood-testing company lost nearly $1 billion of investors’ money before dissolving in 2018.

In a recent CNBC interview, John Carreyrou, the Wall Street Journal (WSJ) investigative journalist who first broke the Theranos story in 2015, contended that the once-high-flying Silicon Valley startup could have paid back investors on a pro-rata basis, but that the company opted to use its dwindling cash to challenge lawsuits.

“If you rewind to October 2015, when I finished, when I published my first investigative story on Theranos, the company still had $400 million in the bank and it could have called it quits then,” Carreyrou said in the interview. “And Elizabeth Holmes could have apologized to investors, to patients, to everyone she had misled and returned that money to shareholders on a pro-rata basis.”

Theranos Scandal Breaks Wide Open

Carreyrou’s nearly year-long Wall Street Journal investigation into Theranos helped bring down the venture capital darling that had achieved a $9 billion private valuation before crumbling under the weight of fraud allegations. Dark Daily and our sister publication The Dark Report (TDR) covered in detail the allegations against and investigation into the embattled blood test company in dozens of e-briefings and TDR articles starting in 2015.

In fact, The Dark Report was first to publish the news that Theranos had ceased using its finger-stick collection method in Phoenix as early as April 2015. (See TDR, “Theranos: Many Questions, But Very Few Answers,” April 20, 2015.) At that time, Theranos declined to respond to The Dark Report’s requests for comments.

Theranos had built its superstar reputation on the backs of a revolutionary finger-prick blood testing system, which Holmes promised could diagnosis diseases ranging from diabetes to cancer with just a few drops of blood. But an in-depth investigation into hoopla surrounding the company’s breakthrough technology by Carreyrou and other reporters at the Wall Street Journal revealed it was based on false test results and phony claims to investors and companies, such as Walgreens, which had planned to feature the technology in their retail clinics. 

Elizabeth Holmes former CEO of Theranos
Elizabeth Holmes (above), founder and former CEO of now defunct Theranos, was considered a wunderkind when, as a 19-year-old Stanford University dropout, she founded Theranos in 2003. Early on, she attracted high-profile members to the Theranos board, including former US Secretary of State George Schultz, and cultivated comparisons to legendary Apple CEO Steve Jobs. But once the accuracy of Theranos’ capillary blood-test device fell under suspicion, Holmes’ fall from grace was swift, as clinical laboratories learned from multiple Dark Daily e-briefings and articles in The Dark Report going back to 2015. (Photo copyright: The New York Times.)

In 2016, Theranos received sanctions from the Centers for Medicare and Medicaid Services (CMS), which included revocation of the company’s CLIA certificate and sanctions against Holmes and other company officials that prohibited them from owning or operating a medical laboratory for two years. Soon afterward, Theranos laid off 340 workers, closed its laboratory operations, and shuttered its wellness centers to “focus on an initiative to create miniature medical testing machines,” the New York Times reported.

When Theranos was finally dissolved in September 2018, Carreyrou reported that the company had an estimated $5 million in cash to distribute to unsecured creditors. All told, Carreyrou estimates Theranos’ investors, which included such big names as News Corp Executive Chairman Rupert Murdoch, Bechtel Group Chairman Riley Bechtel, and US Education Secretary Betsy DeVos, lost nearly $1 billion.

While Holmes’ star was fading, Carreyrou’s fame was rising with the 2018 publication of his best-selling book on Theranos’ downfall, titled, “Bad Blood: Secrets and Lies in a Silicon Valley Startup.”

Theranos’ Final Chapter

Today, Holmes is preparing to stand trial on a dozen federal wire fraud and conspiracy to commit wire fraud charges at the US District Court in San Jose, Calif., where jury selection is slated to start on March 9, 2021, amid COVID-19 pandemic safety precautions.

According to the Mercury News, Holmes faces maximum penalties of 20 years in prison and a $2.75 million fine, plus possible restitution. Carreyrou does not expect Holmes to seek a plea deal.

“I think that the chances of that are pretty unlikely. From what I hear, she’s telling her friends and her entourage that she’s actually looking forward to her day in court and she thinks that the real story—her version of the story—will come out at trial,” he told CNBC. “And so, she’s actually putting on a cheerful face with people she knows, and people have seen her recently and are saying that she’s looking forward to see this go to a jury.”

While the final chapter of this story will be written by a federal court jury, clinical laboratory leaders likely will want Holmes to face maximum penalties if found guilty of all charges. The deceptive scientific and business practices Theranos allegedly engaged in caused many headaches for the clinical lab directors of hospitals and health networks as their CEOs asked why the “cheap and fast” Theranos testing system could not be used instead of traditional, more expensive testing methods.

Theranos also financially damaged investors who might otherwise have gained capital and continued to invest in more credible startups of diagnostic companies and clinical laboratories.

Oak Street Health Opens Three Primary Care Clinics in Walmart Supercenters in Texas with Full Menu of Clinical Services

The clinics are part of a growing trend among large retailers to open full-service healthcare clinics where consumers seek out other goods and services

Major retail chains continue to partner with local health systems and other healthcare companies to expand the range of primary care services delivered in their stores. The latest such collaboration is a partnership between Walmart (NYSE:WMT) and Oak Street Health (NYSE:OSH) at three locations in Texas.

Why is this trend important for clinical laboratories to follow? Because after 15 years, retail chains are moving past the simple walk-in clinic model of using a nurse practitioner to provide limited diagnoses that produce prescriptions at chain store pharmacies and other retail locations. They are now partnering with local health systems to provide full healthcare services that are delivered by physicians. These medical services include many common clinical laboratory tests.

The new OSH clinics, located in Walmart Supercenters, are open and accepting patients via walk-in, same day, and scheduled appointments. The clinics are located in the Dallas-Fort Worth area at:

  • Arlington Walmart, 4801 S Cooper St, Arlington, TX, 76017
  • Benbrook Walmart, 8840 Benbrook Blvd, Benbrook, TX, 76126
  • Carrollton Walmart, 1213 E Trinity Mills Rd, Carrollton, TX, 75006

The clinics offer comprehensive, preventative, and urgent care services to consumers, including:

  • Primary care
  • Optometry
  • X-rays
  • Dental
  • Behavioral counseling
  • Hearing services
  • Nutrition and fitness

As well as clinical laboratory testing, including:

  • A1C
  • Lipid
  • Pregnancy
  • Strep
  • Mono
  • Flu
  • Drug screenings, and more.

 “While all members of the community—from toddlers to seniors—are welcome at these clinics, Oak Street Health’s focus in its growing network of more than 60 primary care centers remains adults on Medicare,” states an OSH press release.

This partnership between Walmart and Oak Street Health means clinical labs in that area will need to follow their patients to be able to collect the specimens and perform the lab tests for patients seen in Walmart Health clinics.

Walmart Health Center Outside Inside
In, “Walmart Opens Second Health Center Offering Clinical Laboratory Tests and Primary Care Services,” Dark Daily reported in May on similar Walmart Health Center openings like that shown above in partnership with WellStar Health System in Georgia. These full-service primary care centers offer many common clinical laboratory tests. “By offering clinical laboratory testing in support of primary care and urgent care, Walmart may be able to lower prices for lab tests in any market that it enters,” said Robert Michel, Editor-in-Chief of Dark Daily and its sister publication The Dark Report. (Photo copyright: Walmart.)

Oak Street Health Brings Value-based Medicine to 11 States

“It is our mission at Oak Street Health to rebuild healthcare as it should be, and that aligns directly with Walmart’s history of providing accessible and equitable healthcare in communities across the country,” said Mike Pykosz, CEO of Oak Street Health, in the press release. “We look forward to becoming a positive addition to the neighborhood in these new markets and providing an unmatched healthcare experience in a convenient location.”

Both companies are planning to extend their relationship beyond these three locations and open additional clinics in other regions.

“We’ve proudly served customers at these three former Walmart Care Clinic locations for the last five years, and we are excited to bring this evolved approach to healthcare to our customers at these locations with Oak Street Health,” said Marcus Osborne, Senior Vice President, Walmart Health, in the press release. “As we grow Walmart Health locations in other markets, we think Oak Street Health’s innovative value-based healthcare model will help us continue to deliver on our live better promise at these locations.”

The majority of Oak Street Health consumers are Medicare Advantage patients, but OSH does accept most major and commonly-accepted insurance plans, Healthcare Dive reported.

Full-Service Healthcare Clinics Drawing Investor Attention

There is evidence that savvy investors believe moving primary care into retail stores and other non-traditional locations can be a big winner. In its third quarter report, Oak Street Health released very strong numbers for their third quarter, which ended September 30. Their total reported revenue for the quarter was $217.9 million, which accounted for a 57% increase over last year’s third quarter earnings, Yahoo Finance reported.

OSH’s capitation revenue totaled $211.8 million, according to the report, which was a 59% increase year over year. Law Insider defines capitation revenues as “all payments from managed care organizations, where payment is made periodically on a per member basis for the partial or total medical care needs of a patient, co-payments, and all HMO incentive bonuses.”

In its third quarter statement, Oak Street Health also reported caring for approximately 59,500 at-risk patients, which represented 66% of its total patients.

“Our strong third quarter results were highlighted by 38% growth in at-risk patients, 57% revenue growth, and the resumption of new center openings, as we opened 13 centers during the quarter amidst continued uncertainty related to the COVID-19 pandemic,” said Pykosz in a statement, Yahoo Finance reported. “Looking ahead, we continue to be excited by the ample opportunity to drive continued de novo expansion across both new and existing markets, as well as the complementary growth opportunities presented by our Walmart collaboration and CMS’ Direct Contracting program.”

As we wrote in the May Dark Daily e-briefing, “Clinical laboratory leaders may want to explore partnerships with Walmart and other retailers that are developing healthcare centers to deliver primary care services in places where masses of people shop for everyday items. Especially given that these big-box retailers remain open during healthcare crises like the COVID-19 pandemic.”

This is even more critical now, as more retailers partner with health systems to provide expanded primary care and clinical laboratory services.

Immunocompromised Patients with COVID-19 May Remain Infectious for Much Longer than Previously Thought

Clinical laboratory professionals should note that one case study describes a COVID-positive cancer patient shedding infectious particles for five months, which is much longer than expected

Just when researchers start believing they understand COVID-19 infections, something happens that reveals there is still more to learn. These additional findings are relevant for clinical laboratory managers and pathologists because the new insights often may play a role in how SARS-CoV-2 results should be interpreted for individual patients.

Researchers recently described a case where, in February, a 71-year-old woman underwent surgery related to her 10-year battle with cancer. While she was in the hospital, she was found to be positive for the SARS-CoV-2 coronavirus, though she showed no respiratory or systemic symptoms. Nevertheless, the hospital isolated her and monitored the infection.

To everyone’s surprise, the patient remained positive for five months. She underwent 15 COVID-19 tests from various diagnostics companies, as well as receiving two doses of convalescent plasma therapy, but she remained positive for the coronavirus into June.

Researchers at the National Institute of Allergy and Infectious Diseases (NIAID) wanted to know why. They conducted a study on the woman, which they later published in the journal Cell, titled, “Prolonged Infectious SARS-CoV-2 Shedding from an Asymptomatic Immunocompromised Individual with Cancer.”

In their published study, they wrote, “Although it is difficult to extrapolate from a single individual, our data suggest that long-term shedding of infectious virus may be a concern in certain immunocompromised people. Given that immunocompromised individuals could have prolonged shedding and may not have typical symptoms of COVID-19, symptom-based strategies for testing and discontinuing transmission-based precautions, as recommended by the Centers for Disease Control and Prevention (CDC), may fail to detect whether certain individuals are shedding infectious virus.”

Clinical laboratory professionals and pathologists will find it significant that patients with major health conditions may be shedding viral material for weeks longer than originally thought. This is relevant because it may be prudent to COVID test patients who present with compromised immune systems, and who are asymptomatic, and then repeat that testing at appropriate intervals.

The graphic above taken from the NIAID study
The graphic above taken from the NIAID study shows how long it took for the SARS-CoV-2 coronavirus to clear the 71-year-old immunocompromised cancer patient’s system, and at which points the convalescent plasma doses were administered. (Graphic copyright: National Institute of Allergy and Infectious Diseases.)  

Immunocompromised Patients May Handle COVID-19 Differently

The NIAID researchers believe the reason the patient continued to shed infectious virus for so long was because she was immunocompromised. They wrote, “Many current infection control guidelines assume that persistently PCR-positive individuals are shedding residual RNA and not infectious virus, with immunocompromised people thought to remain infectious for no longer than 20 days after symptom onset. Here we show that certain individuals may shed infectious, replication-competent virus for much longer than previously recognized. Although infectious virus could be detected up to day 70, sgRNA, a molecular marker for active SARS-CoV-2 replication, could be detected up until day 105.”

In the United States, some three million people have compromised or weakened immune systems. This is a significant population, Science Alert reported.

“As the virus continues to spread, more people with a range of immunosuppressing disorders will become infected, and it’s more important to understand how SARS-CoV-2 behaves in those populations,” Vincent Munster, PhD, Chief, Virus Ecology Unit at the National Institute of Allergy and Infectious Diseases and co-author of the NIAID study, told Science Alert.

The NIAID study findings match knowledge about other coronaviruses. For example, Science Alert reported that immunocompromised people with Middle East Respiratory Syndrome (MERS) have been shown to shed common seasonal coronaviruses for up to a month following infection.

Asymptomatic Patients Are a Mystery

There is still much that is unclear about asymptomatic patients. A paper published in JAMA, titled, “Clinical Course and Molecular Viral Shedding Among Asymptomatic and Symptomatic Patients with SARS-CoV-2 Infection in a Community Treatment Center in the Republic of Korea,” questioned the viral load differences in patients who tested positive but had no symptoms compared to those who were symptomatic.

That study included 303 patients, of which 193 were symptomatic. During the course of the study, 21 of the asymptomatic patients developed symptoms, however, the viral load was similar in all of the patients, regardless of symptoms.

“Isolation of asymptomatic patients may be necessary to control the spread of SARS-CoV-2,” concluded the JAMA researchers. But how long should asymptomatic patients remain isolated?

Official Guidance Is Based on Symptoms

The CDC updated its guidelines for who should isolate and for how long in October. The guidelines cover:

  • People who have or had COVID-19 and had symptoms;
  • People who tested positive for COVID-19 but did not have symptoms;
  • People who either had severe symptoms of COVID-19 or who have a compromised immune system;
  • People who were exposed to COVID-19, and
  • People who have been reinfected.

Regarding those who are immunocompromised and had COVID-19, the CDC says they “may require testing to determine when they can be around others.”

In addition to noting that people who are immunocompromised may require additional testing, the CDC is also continuously updating its published list of people who are at risk for complications and severe illness if they contract COVID-19. However, as the NIAID study showed, even those with underlying medical conditions can be asymptomatic.

And as the NIAID researchers note, there is more to learn. “Understanding the mechanism of virus persistence and eventual clearance will be essential for providing appropriate treatment and preventing transmission of SARS-CoV-2 because persistent infection and prolonged shedding of infectious SARS-CoV-2 might occur more frequently. Because immunocompromised individuals are often cohorted in hospital settings, a more nuanced approach to testing these individuals is warranted, and the presence of persistently positive people by performing SARS-CoV-2 gRNA and sgRNA analyses on clinical samples should be investigated.”

SARS-CoV-2 Science Is Young

An additional takeaway for pathology lab professionals is the reminder that the scientific research surrounding the novel coronavirus that causes COVID-19 is very young. New insights and understanding will continue to emerge, probably for many years.

One reason why the development of vaccines for COVID-19 has been so quick is that it built on scientific knowledge of the first SARS outbreak and MERS. It’s interesting to note that both SARS and MERS are relatively new as well: SARS emerged in 2002 and MERS in 2012. Compared to a disease like HIV, which was first identified in 1959, scientists have only been working on these particular coronaviruses for a short period of time.

The NIAID study is yet another example of new knowledge and insights emerging about how SARS-CoV-2 infects individuals. Collectively, these findings make it challenging for medical laboratory professionals to stay current with everything relevant and associated with the proper interpretation of COVID-19 test results.

For years, Dark Daily and its sister publication The Dark Report have regularly predicted that the traditional fee-for-service reimbursement model of indemnity health insurance that requires beneficiaries to pay a co-pay is on the way out. What is not known is how the nation’s biggest health insurers plan to reinvent themselves, as value-based reimbursement for providers becomes more common.

That may be clearer now, at least for one insurance giant. Aetna recently announced it was incorporating CVS Health services provided at CVS-owned pharmacies and retail clinics into a healthcare plan for individuals in the greater Kansas City, Mo., area. 

The Aetna Connected Plan “combines CVS Health services—including free one to two-day prescription delivery and 20% discounts on thousands of health-related items—with Aetna’s cost-saving I-35 Performance Network to deliver a more convenient and connected member experience, along with up to 20% premium savings compared to comparable PPO products in the market,” states a CVS Health press release.

Members can schedule appointments at CVS Health MinuteClinics, request consultations at CVS HealthHUBs for no copay, and access other services, including telehealth visits, through CVS pharmacies. Essentially, Aetna made network providers for this range of CVS-owned health services.

CVS Health services, according to the press release, include:

  • $0 copay at local HealthHUB and MinuteClinic locations,
  • Free one to two-day prescription delivery,
  • 20% discounts on thousands of health-related items in-store and online,
  • 24/7 pharmacist helpline, and
  • Access to the CVS managed pharmacy network, specialty pharmacy network, and Coram home infusion services.

The Aetna I-35 Performance Network includes:

  • 1,247 primary care doctors,
  • 8,300 specialists,
  • 13 hospitals, and
  • 32 urgent care facilities

The Aetna health plan will be made available next year to employers with 101 or more workers in three counties in Missouri (Clay, Jackson, and Platte) and two counties in Kansas (Johnson and Wyandotte). Aetna claims the premiums for their new plan are 20% less expensive than other similar plans for the region, MedCity News reported.

“It’s all about meeting our members where they are to increase engagement, improve outcomes, and reduce healthcare costs,” said Jim Boyman (above), VP, Market President-Heartland at Aetna, in the press release. “This plan is just one example of how Aetna and CVS Health are combining forces to help people live healthier lives,” he added. “We’re providing a better member experience by reducing costs and simplifying their healthcare journey.” (Photo copyright: LinkedIn.)

AMA Expressed Concerns over CVS Purchase of Aetna

CVS acquired Aetna for $70 billion in late 2018 and the two companies have been working to integrate their businesses ever since. 

There are currently more than 1,000 CVS MinuteClinics located throughout 33 states and the District of Columbia. CVS began opening HealthHUB clinics in the Houston area last year and plans to open more than 1,500 HealthHUBs by the end of 2021, the Houston Chronicle reported.

Critics of the 2018 purchase of Aetna by CVS were concerned that CVS would somehow use Aetna’s 40 million members to drive revenue for its stores. Many groups, including the American Medical Association (AMA), Consumers Union, and pharmacy organizations were opposed to the merger due to anticompetitive concerns.

The AMA felt the merger would reduce competition in some pharmaceutical markets, which could lead to higher premiums and lower the quality of some insurance products. The organization also believed that the merger “faced enormous implementation challenges and was unlikely to realize efficiencies that benefit patients,” the AMA noted in a statement.

“We are very concerned about the consolidation in healthcare because we know that as healthcare systems consolidate, prices tend to go up,” AMA President Barbara McAneny, MD said in the statement. “And we are very concerned that with the CVS purchase of Aetna that drug prices will continue to rise and that is a major pain point of patients all across the country.”

The AMA also stressed concerns regarding how the lack of competition could have negative impacts on the pharmaceutical industry.

“It’s also causing harm to a lot of the parts of the industry,” McAneny added. “Independent pharmacies are going out of business and this consolidation makes them (CVS) just such a stronger player in that market that competition is really difficult.”

Despite the opposition, the CVS and Aetna merger received final approved from regulators last year. Before the merger was approved, the two companies had to convince state attorneys general, antitrust regulators, and Congress that the consolidation would not result in anticompetitive practices and impair independent drugstores and other national chains. 

Will Aetna Engage Independent Clinical Laboratories?

Aetna’s new health plan is another example of how the nation’s biggest health insurers are adapting away from fee-for-service and to value-based reimbursement for healthcare providers. Clinical laboratory managers will want to watch how CVS and Aetna do or do not work with independent laboratory companies to collect lab specimens at the pharmacies and provide testing.
