Walmart Opens Second Health Center Offering Clinical Laboratory Tests and Primary Care Services

In another example of giving consumers more direct access to medical laboratory tests, Walmart believes that convenience and lower prices can help it capture market share

Retail giants continue to add healthcare services—including medical laboratory testing—to their wares. It’s a trend that pressures hospital systems, clinical laboratories, pathology groups, and primary care providers to compete for customers. And, while in most instances competition is good, many local and rural healthcare providers cannot reduce their costs enough to be competitive and stay in business.

This is true at Walmart (NYSE:WMT), which recently opened its second “Health Center” in Georgia and announced prices for general healthcare services 30% to 50% below what medical providers typically charge, reported Modern Healthcare.

The services offered at the new Walmart Health Center in Calhoun, a suburb of Atlanta, include:

  • Primary care
  • Dental
  • Counseling
  • Clinical laboratory testing
  • X-rays
  • Health screening
  • Optometry
  • Hearing
  • Fitness and nutrition
  • Health insurance education and enrollment

A Walmart news release states, “This state-of-the-art facility provides quality, affordable and accessible healthcare for members of the Calhoun community so they can get the right care at the right time … in one facility at affordable, transparent pricing regardless of a patient’s insurance status.”

The fact that Walmart posts “Labs” on the Health Center’s outdoor sign may indicate the retail giant considers easy access to clinical laboratory testing a selling point that will draw customers.

“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, and President of The Dark Intelligence Group.

Healthcare Transparency and Lower Prices

The 1,500 square-foot free-standing Walmart Health Centers offer more services than the in-store Care Clinics installed in other Walmarts throughout Georgia, South Carolina, and Texas. For its healthcare services, Walmart established partnerships with “on-the-ground” health providers to offer affordable services.

“We have taken advantage of every lever that we can to bring the price of doing all of this down more than any hospital or group practice could humanly do. Our goal, just like in the stores, is to get the prices as low as we can,” Sean Slovenski, Senior Vice President and President of Walmart Health and Wellness, told Bloomberg Businessweek.  

Some of the clinical laboratory prices prominently posted in the building and noted on the Health Center online price list include:

  • Primary care physician office visit $40
  • Lipid $10
  • Hemoglobin A1c $10
  • Pregnancy Test $10
  • Flu Test $20
  • Strep Test $20
  • Mono Test $20

Meanwhile, the average cost to visit a primary care doctor is $106, according to Health Care Cost Institute data cited by Business Insider, which noted that Walmart’s rates “could be a steep mountain for traditional providers to climb.”

However, Rob Schreiner, Executive Vice President of WellStar Health System in Northern Georgia told Modern Healthcare that “Walmart will offer a cheaper alternative for working-class families who may not have health insurance and may not have an established relationship with a primary care provider.”

Convenient Access to Quality Healthcare Services a Major Draw

At a freestanding Walmart Health Center, people can park near the entrance and walk a few steps to the entrance, rather than traversing aisles to a Care Clinic inside a Walmart Supercenter. And for many customers, finding a Walmart Health Center may not be as complicated or stressful as visiting doctors’ offices.

That seems to be Walmart’s goal—not simply using the Health Centers to increase traffic in its stores, Slovenski said. “We are trying to solve problems for our customers. We already have the volume,” he told Forbes. “We have the locations and the right people. We are creating a supercenter for basic healthcare services.”

Walmart’s arrangement with local healthcare providers differs from traditional primary care clinics staffed by doctors who are practice owners, or who are employed by nearby hospitals and health systems.

“The whole design of the clinic is curious to most of the doctors here [in Dallas, Ga.],” Jeffrey Tharp, MD, Chief Medicine Division Officer, WellStar Medical Group, told Modern Healthcare. “We are advocating integration into our network, for instance with patients who need a cardiologist coming from Walmart to WellStar.”

Other Retailers Offering Primary Care Services

Walmart is not the only retailer moving into the outpatient healthcare market. Dark Daily recently reported on CVS Health’s and Walgreens’ strategies in delivering primary care, as well as on the Amazon Care pilot program, which may lead to Amazon becoming a primary care provider as well. (See, “Amazon Care Pilot Program Offers Virtual Primary Care to Seattle Employees; Features Both Telehealth and In-home Care Services That Include Clinical Laboratory Testing,” January 31, 2020.)

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.

Previously High-Flying Theranos Provides Clinical Laboratories and Pathology Groups with Valuable Lesson on How Quickly Consumer Trust Can Be Lost

Affected patients speak about emotional, financial, and medical costs of receiving inaccurate results from the startup’s faulty Edison ‘finger-stick’ blood draw testing device

Healthcare consumers trust America’s clinical laboratories and anatomic pathology groups to provide accurate test results. When those test results are inaccurate, the loss of public trust can trigger a sharp decline in referrals/revenue and draw an avalanche of lawsuits by those harmed by inaccurate results.

The most recent example of this object lesson is disgraced blood testing company Theranos, previously estimated to be worth $9 billion but now struggling to stay afloat. The once high-flying startup has been brought to the edge of bankruptcy in the aftermath of a fraud settlement with the Securities and Exchange Commission (SEC), sanctions from the Centers for Medicare and Medicaid Services (CMS), investor lawsuits, consumer lawsuits, and a settlement with Walgreens over claims about Theranos’ Edison portable blood analyzer.

Theranos first made its unproven finger-stick blood draw device available to consumers in September 2013, when it announced a partnership with drugstore chain Walgreens (NASDAQ:WBA). At its height, Theranos operated 40 “Wellness Centers” in Walgreens stores in Arizona and a single location in California, which were the source of much of its revenue. USA Today reported the metro Phoenix-area centers alone sold more than 1.5 million blood tests, which yielded 7.8 million tests results for nearly 176,000 consumers. Theranos shuttered the wellness centers in 2016 after CMS inspectors found safety issues at Theranos’ laboratories in California and a Wall Street Journal (WSJ) investigation raised questions about the company’s testing procedures and accuracy claims. Ultimately, Theranos voided the results of all blood tests run on its Edison device from 2014 through 2015.

Breast-cancer survivor Sheri Ackert (above) told the WSJ she panicked when blood-test results from Theranos indicated her cancer may have reoccurred or were indicative of a rare type of tumor. After being retested by a different clinical laboratory, her results were found to be normal. Click here to watch a WSJ video about Ackert’s experience. (Photo/video copyright: Mark Peterman/Adya Beasley/Wall Street Journal.)

USA Today outlined the impact Theranos’ supposedly low-cost, cutting-edge technology had on several customers:

  • A woman inaccurately diagnosed with the thyroid condition Hashimoto’s disease changed her lifestyle, made unnecessary medical appointments, and took medication she didn’t need;
  • A woman inaccurately diagnosed with the autoimmune disease Sjögren’s syndrome was checked for food allergies before being retested and found not to have an autoimmune condition; and,
  • An Arizona resident who had heart surgery visited a Theranos clinic five times to monitor the results of blood-thinning drug warfarin and was switched to a different drug. He had to have a second heart surgery to drain blood from the pericardial sac and believes more accurate test results could have averted the follow-up operation.

Arizona resident Steven Hammons visited a Theranos clinic several times to have his blood tested. He’d been placed on blood thinners following heart surgery. He was taken off the blood thinners presumably based on the results of those tests. However, as USA Today reported, one test result was later found to be inaccurate. Hammons, who underwent a second procedure to remove blood that had built up around his heart, told USA Today he was concerned about the safety of his fellow citizens.

“That makes me very concerned and worried for the safety of other Arizonans,” said Hammons, who once worked in the medical services division of a private health insurance company. “Government had a role in patient safety. The powers that be dropped the ball.”

Arizona Attorney General Mark Brnovich spearheaded a lawsuit against Theranos under the state’s Consumer Fraud Act, which led to a $4.65 million settlement covering full refunds for every Arizona customer who used the company’s testing services.

“Theranos may have not only had some erroneous test results, but they may have misread my rising blood pressure level as well,” Brnovich told The Republic in a 2017 article announcing the state’s fraud settlement with Theranos. “They said that about 10% of the results were inaccurate. The problem is, as an Arizona consumer, you don’t know whether you were part of that class or not.”

Downfall of a Once-Vaunted Clinical Laboratory Company

Dark Daily and sister publication The Dark Report have written extensively about these events. Former CEO Elizabeth Holmes founded Theranos in 2003 when she was just 19-years old. By 2013, Holmes had become a media sensation based on her claims that “Theranos had developed a medical technology that could do what seemed to be impossible: Its secret machines could run thousands of medical tests using the blood from a tiny finger-prick, and do so quickly and cheaply,” Bloomberg reported in a recent article outlining Holmes’ fall from grace.

While Holmes continues in the role of Chairman of Theranos’ Board of Directors, she was stripped of control of the company as part of the SEC settlement in 2016. The SEC found Holmes and then-company President Ramesh “Sunny” Balwani had fabricated claims Theranos technology had been validated by the Food and Drug Administration (FDA) and pharmaceutical companies and battle-tested by the US military in Afghanistan.

As a result, the SEC also barred Holmes from serving as an officer or director of any public company for 10 years. In October 2016, Theranos announced it would be closing its laboratory operations and focusing on its effort to create miniature medical testing machines, which it did. Nevertheless, the fallout continues.

As pressures on medical laboratories and pathology groups to cut costs while delivering quality care and value increases, laboratory leaders must not lose sight of the fact that accuracy of results remains the key to maintaining trust with healthcare consumers and a financially viable business.

Quest Diagnostics and LabCorp Ink Deals to Put Patient Services Centers in Grocery Stores and Retail Pharmacies, But Not for the Same Reasons as Theranos

Agreements to open PSCs in the nation’s largest retail grocery and pharmacy chain stores shows a willingness by clinical laboratories to attract customers through convenience

Greater use of retail stores as the location for patient services centers (PSCs) may be an important new trend for the clinical laboratory industry. That’s because, historically, medical laboratories placed most of their patient service centers in hospital campuses or near medical office buildings.

However, in recent months, both of the nation’s billion-dollar lab companies signed deals with national retailers to put patient service centers in their stores. Dark Daily believes that the motivation for a lab company to put a PSC into a grocery store or retail pharmacy is to make it easier and more convenient for a patient to get their specimen collected at a location that is closer to their home or office. In other words, it is faster for the patient to get to their nearest grocery store for a blood draw than to travel to the hospital campus in their community.

Various news reports indicate that Quest Diagnostics (Quest) may be more active than Laboratory Corporation of America (LabCorp) in opening PSCs in grocery stores and retail pharmacies. Over the last four months, Quest has announced plans to open patient services centers with several retailers, particularly in the states of Texas and Florida. Similarly, in the past four weeks, LabCorp disclosed an agreement with Walgreens Boots Alliance (Walgreens).

Ground zero for this current interest in putting PSCs into retail stories is Phoenix, Arizona. In 2014, to serve its direct-to-consumer lab testing business model, Theranos had PSCs in about 40 Walgreen’s pharmacies. Pathologists and clinical laboratories will recall that in November, 2015, Sonora Quest Laboratories of Phoenix opened a patient service center (PSC) in a Scottsdale, Ariz., supermarket owned by Safeway. It was the first PSC Sonora Quest had opened in collaboration with a grocery store chain, but it was not the last. Less than a year later, Sonora Quest and Safeway expanded their operations by opening additional PSCs in stores throughout the Grand Canyon State.

At the same time Sonora Quest was stepping into the retail blood-drawing business, Theranos of Palo Alto, Calif., was exiting it after opening 40 PSCs in Walgreens pharmacies, most of them in Arizona. However, before leaving the lab-testing business altogether, the embattled company put a lot of effort into educating consumers about the benefits of purchasing lab tests without a physician’s order. Theranos had even supported a bill (HB2645) the Arizona State Legislature passed that allowed patients to order tests without a physician’s requisition.

Now, in 2017, Quest Diagnostics (NYSE:DGX) appears interested in following a similar strategy as Theranos and Sonora Quest by developing Quest-branded PSCs in retail chain stores. On its website, Quest states that in the past several years it has opened 106 PSCs in Albertsons, Randalls, Safeway, Tom Thumb, and Vons retail stores in nine states.

Quest Moves to Open PSCs Across America

Quest has PSCs in the following states:

  • California (12 stores);
  • Colorado (27);
  • Delaware (1);
  • Maryland (9);
  • Montana (4);
  • Oregon (10);
  • Texas (26);
  • Virginia (7); and
  • Washington State (10).

In June 2017, Quest announced it would open 10 additional PSCs in Tom Thumb retail stores in North Texas by the end of the month. Thom Thumb is a division of Albertsons, a food and drug retailer with stores nationwide. In the same announcement, Quest said it plans to open PSCs in 200 Albertson’s-owned stores nationwide by the end of the year.

Give Blood Then Shop

Also in June, Quest and Walmart (NYSE:WMT) announced a deal in which the two companies would open co-branded PSCs in 15 Walmart stores in Florida and Texas by the end of 2017.

In these locations, Quest encourages patients to have their blood drawn and then shop. Such locations can accommodate collecting specimens for routine blood work, such as total cholesterol and white blood cell count, as well as complex gene-based and molecular testing. Even patients with such chronic conditions as cancer, diabetes, and hepatitis, are encouraged to use these PSCs, the lab-testing company stated in the announcement.

Not to be outdone, LabCorp also announced a deal with Walgreens in June. In Forbes, Bruce Japsen reported that Walgreens (NASDAQ:WBA) announced it would collaborate with LabCorp (NYSE:LH) to develop and operate PSCs in Walgreens drugstores in Colorado, Illinois, and North Carolina.

The deal is the first for Walgreens since its troubled relationship with Theranos ended last year. Walgreens’ collaboration with LabCorp will initially begin this summer with five patient service centers in Denver and one in Morrisville, N.C. A seventh location in Deerfield, Ill., will open by the end of the year. Financial terms of the partnership were not disclosed.

Lessons Clinical Laboratories Learned with PSCs in Retail Stores

For Quest, the speed with which it is opening new PSCs is significant, because it seems to have taken lessons that Theranos and Sonora Quest learned earlier in Ariz. and applied them to markets nationwide. It’s worth noting that Safeway and Albertsons were already two of the largest retail grocery chains in the nation before they merged in 2015.

So, while Sonora Quest was working with Safeway, its parent company, Quest, was working with Albertsons.

One other point that is significant about Quest’s efforts is that not many other clinical laboratories have a presence in retail stores. It’s unknown just how much specimen volume these retail operations generate for Quest, one of the largest clinical lab companies in America. And, it is unknown if these PSCs in retail settings are breaking even or making a profit.

One result, however, is clear. That Quest is being so aggressive in opening PSCs testifies to the company’s level of interest in serving consumers directly. In other words, these PSCs are not primarily a direct-to-consumer play, but are aimed at building market share by adding regular lab testing done for patients. In this way, the direct-to-consumer business that Quest generates is a bonus.

The deals by Quest and LabCorp also imply that both clinical laboratory companies are willing to bet on the fact that consumers may prefer the convenience of using PSCs located in retail stores they currently frequent, rather than going to patient service centers in hospitals and sitting in a waiting rooms.

Up to 50% of Aetna, UnitedHealth Group, and Anthem Reimbursements Go to Value-Based Contracts; Clinical Laboratories Must Implement Value-Based Strategies to Remain Competitive

Aetna expects 75% to 80% of its medical spending will be value-based by 2020

Many pathologists and medical laboratory executives may be surprised to learn how quickly private health insurers are moving away from fee-for-service payment arrangements. According to Forbes, the nation’s largest health insurance companies now associate nearly 50% of reimbursements they make to value-based insurance initiatives.

This is a sign that value-based managed care contracting continues to gain momentum. And that interest remains strong in this form of reimbursement, which associates payment-for-care to quality and rewards efficient providers.

UnitedHealth Group (NYSE:UNH) and Aetna (NYSE:AET) are the fastest adopters of value-based payment models, with Anthem (NYSE:ANTM) close behind, the Forbes article noted.

Moreover, UnitedHealth and Aetna intend to increase their percentage of value-based contracts. For example, Aetna, which now ties 45% of its reimbursements to value, says its goal is to have 75% to 80% of its medical spending in value-based relationships by 2020, Healthcare Finance News pointed out.

These compelling data should motivate pathology groups and medical laboratory leaders to adopt strategies for value-based contracting. That’s because payment schemes based on clinical laboratory performance will likely grow quickly, as compared to traditional fee-for-service reimbursement models, which are being phased out.

Aetna: Lowering Acute Admits

Aetna and other insurance companies are rewarding in-network hospitals, medical laboratories, and physicians who help them keep their customers healthy.

“One way we measure our success is by how well we are able to keep our members out of the hospital and in their homes and communities,” stated Mark Bertolini, Aetna’s Chairman and Chief Executive Officer, in the Healthcare Finance News article.

“I think value-based contracting is going to continue to be encouraged by even the current [federal] administration as a way of getting a handle on healthcare costs,” he continued. In fact, Aetna lowered acute admissions by 4% in 2016 and reduced readmission rates by 27%, reported Healthcare Finance News.

UnitedHealth: Outpatient Care a Focal Point

Meanwhile, UnitedHealth Group spends $52 billion (or about 45%) of a $115 billion annual budget on value-based initiatives, Forbes noted.

In March, UnitedHealth Group joined Optum, its health services company, to Surgical Care Associates, an ambulatory (outpatient) surgery provider with 205 sites nationwide.

As surgical cases (such as total joint replacements) continue their migration to ambulatory surgery center sites, UnitedHealth Group expects this merger to offer value to patients, payers, and physicians, a statement pointed out.

“We’ve been able to drive down on a per capita basis inpatient, and inside that we’ve focused a lot in those early years around the conversion of inpatient to outpatient. And I think this is sort of the continued evolution as we focus more on the side of service to how do we get that outpatient into the ambulatory setting,” said Dan Schumacher, UnitedHealthcare Chief Financial Officer, in the Healthcare Finance News story.

 

The graphic above is from a slide presentation given by Eleanor Herriman, MD, MBA, Chief Medical Informatics Officer with Viewics, a provider of big-data management solutions for hospitals and clinical laboratories. Because of healthcare’s drive toward value-based payment models, clinical labs must focus on “operational efficiencies” and “testing utilization management,” and be prepared to “demonstrate value of testing to payers and health organizations,” Herriman’s presentation notes. (Image copyright: Viewics, Inc.)

Also, in 2016, OptumRx (pharmacy benefit management) announced partnerships with Walgreens and CVS Pharmacy. The joint pharmacy care agreements are intended to improve patient outcomes, connect platforms for health data leverage, and address costs of care, UnitedHealth Group stated in dual press releases (Walgreens and CVS) announcing the strategic partnerships.

Anthem: Planning for 50% Value-Based Care by Next Year

For its part, Anthem now has 43% of its operating budget focused on shared savings programs. Furthermore, the company reportedly has a plan to associate at least 50% of its budget with value-based care by 2018.

“When you combine this with our pay for performance programs, we will have well over half our spend in collaborative arrangements over the next five years,” Jill Becher, Anthem Staff Vice President of Communications, told Forbes.

Clinical Laboratories Need Value-Based Strategy

The rise of value-based care should motivate clinical laboratory leaders to create and implement novel and responsive strategies as soon as possible. Without a focus on value, labs could be denied entry into provider networks.

In a Clinical Laboratory Daily News article, Danielle Freedman, MD, noted that value-based clinical laboratory strategies could entail the following:

  • Working with physicians on appropriate retesting intervals;
  • Adding clinical decision support tools; and
  • Vetting testing requests.

Freedman is Director of Pathology at Luton and Dunstable University Hospital NHS Foundation Trust in the United Kingdom (UK).

Clinical laboratory executives and pathology practice administrators should take note of the fact that some large healthcare insurers already have nearly half of their reimbursement under value-based contracts, with plans to grow their investment in value-based relationships in the future.

Already facing the challenges of narrowing healthcare networks, it is imperative that lab leaders also get their lab team to focus on value (and not just volume). It can be expected that, as health insurers look to partner with labs in different regions and communities, they will want medical laboratories that are creative in developing high-value diagnostic testing services.

For Embattled Medical Laboratory Company Theranos, Bad News Keeps on Coming After Two Federal Inspections Show Problems in Certain Lab Practices

High rates of variability from one drop to another raise questions about the reliability of point of care testing equipment and companies that collect lab specimens only with finger sticks

Since last fall, one news report after another has come out with bad news for Theranos Inc., the high-profile medical laboratory company. The reports have ranged from dissatisfaction among Theranos’ partners, such as Walgreens and Capital BlueCross, to failed inspection reports from the federal Centers for Medicare and Medicaid Services (CMS) and the U.S. Food and Drug Administration (FDA).

In response, the embattled lab company in Palo Alto, Calif., has maintained that it is doing everything it can to correct any deficiencies in its clinical laboratory testing methods and to ensure its partners that its processes are scientifically sound and its methods valid. (more…)
