Children’s Study Determines MicroRNA in Saliva Can Accurately Diagnose Acute and Prolonged Concussion Symptoms; Could Lead to New Medical Laboratory Tests and Point-of-Care Diagnostics

Research published in JAMA Pediatrics reports that non-invasive salivary microRNA testing identifies prolonged concussion symptoms with 85% accuracy

Sports-related concussions are always tragic, but doubly so when they involve child athletes. Quick diagnoses and treatments are critical to prevent permanent brain injury. But doctors are often hampered by the pace at which traditional medical imaging modalities and clinical laboratory diagnostic technologies provide crucial feedback.

Now, researchers at Penn State Health Children’s Hospital have determined that microRNA in saliva could be used as biomarkers in point-of-care concussion testing during sports events, according to a Penn State Health news release. Such sideline saliva analyses could provide quick feedback to field doctors on whether a head injury is serious enough to put injured athletes out of play, and how long the effects of such injuries might last. But is it accurate?

Jeremiah J. Johnson, MA, BS, Department of Pediatrics, at Penn State College of Medicine in Hershey, Pa., et al, recently published a study in the Journal of the American Medical Association (JAMA) Pediatrics that evaluated the ability of salivary microRNA to identify concussion in children. The salivary test of microRNA levels, Johnson and colleagues argued, does accurately identify the “duration and character of concussion symptoms.” According to the researchers, the test demonstrated high prognostic potential as a “toolset for facilitating concussion management” and may provide an additional biomarker source for use in clinical laboratory testing.

MicroRNA Offers New Biomarkers for Concussion Diagnosis

The study tested the saliva of 52 adolescents with a clinical diagnosis of mild traumatic brain injury in the form of concussion for specific microRNA expressions. Researchers identified five microRNA molecules which “accurately identify” patients with concussion symptoms. Three of those molecules served to diagnose specific symptoms of headache, fatigue, and memory difficulties up to one month after injury with low false detection rates. Because these microRNA molecules are not specific to children, could the test maintain diagnostic accuracy for patients of all ages?

William P. Meehan III, MD, with the Micheli Center for Sports Injury Prevention at Boston General Hospital, and Rebekah Mannix, MD, MPH, with the Brain Injury Center at Boston Children’s Hospital wrote an editorial responding to the original research article stating that “the use of salivary microRNA in this study is both novel and clinically relevant.” Adding that “using this salivary microRNA panel to diagnose and manage concussions could be a major advancement to the field.”

Meehan and Mannix also remarked on the speed and relative ease of obtaining saliva samples, stating that “salivary microRNAs could also offer insights into the underlying biological mechanisms of injuries, potentially identifying specific targets to modify disease.”

More Accurate than Current Concussion Diagnosis Tools

There has been a marked interest in microRNA analysis and testing in recent years. MicroRNA analysis and testing has found use in cancer prognosis and personalized medicine that help predict responses to specific treatments for individual patients with a variety of chronic diseases. The news that microRNA can be used to predict concussion and duration of symptoms further solidifies the role microRNA may play in medical laboratory testing in the near future.

In an interview with CNN, Steve Hicks, MD, PhD, senior author of the JAMA Pediatrics research article and Assistant Professor of Pediatrics at Penn State College of Medicine, reported that the salivary microRNA test predicted concussion with 85% accuracy in comparison to current clinical survey measures, which are “approximately 65% accurate.” Hicks added that “the technology required to measure saliva RNA is already employed in medicine” as a common means of testing for upper respiratory viruses and that “modifying this approach for patients with concussions could potentially provide a rapid, objective tool for managing brain injury.”

Currently the Standard Concussion Assessment Tool, Third Edition (SCAT 3), which includes a series of cognitive and physical tests, is used on sports sidelines to detect concussion symptoms. Hicks notes that one problem with SCAT 3 is that “an athlete may have a concussion even if [his or her] score is ‘normal.’” Therefore, the microRNA saliva test could provide objective evidence of concussion in patients SCAT 3 fails to accurately diagnose.

Too Early to Know How Helpful the Test May Be?   

In the same CNN interview, Neurologist Jeffery Kutcher, MD, head of the Sports Neurology Clinic at The Core Institute in Brighton, Mich., stated that the Penn State study’s findings were “promising” and that “work like this is important because it does provide potential for tests that can be helpful in the clinical setting.” Kutcher cautioned however, that it was “too early to know what this type of tool can do for us.”

In an NPR article, Manish Bhomia, M.Eng., PhD, a brain injury researcher with the Uniformed Services University of the Health Sciences commented that “a saliva test could greatly improve care for young people who don’t have obvious symptoms of a concussion.” Bhomia stated that “micro-RNAs offer a promising way to assess concussions in adults as well as children,” but he is wary to laud saliva tests as the best method of measuring relevant microRNA molecules. Bhomia states that blood samples “which tend to contain greater numbers of the genetic fragments” are perhaps a better option.

Hicks disagrees. In an article from Penn State News, Hicks stated that the novel aspect of this study was that it focused on microRNA levels “in saliva rather than blood.” Thus, a test based on saliva, rather than a phlebotomy stick or more invasive blood testing, requires no need for venous blood.

“The ultimate goal is to be able to objectively identify that a concussion has happened and then predict how long the symptoms will go on for,” Hicks noted in the Penn State News article. “Then, we can use that knowledge to improve the care that we provide for children who have concussions, either by starting medicine earlier or holding them out of activities for longer.”

Quadrant Biosciences, a biotech company in Syracuse, N.Y., that helped fund the study, is hoping to “bring a saliva test for concussion to market in the next 12 to 24 months,” according to Hicks in his CNN interview. If development proceeds as planned, the saliva test could prove a “game changer” for sports medicine diagnostics and possibly open new avenues for related microRNA in clinical laboratory testing.

Collaborative Global Study Casts New Light on Breast Cancer’s Genetic Roots; Will Soon Provide Anatomic Pathologists and Clinical Laboratories with New Tools to Diagnose and Treat Cancer

In the same way that BRCA1 and BRCA2 mutations helped pathologists identify women with increased breast cancer risks in the late 1990s, this new study isolates an additional 72 mutations medical laboratories may soon use to diagnose breast cancer and assess risk factors

For 20 years genetic scientists, anatomic pathologists, and medical laboratories have employed the BRCA1/BRCA2 genes to identify women at higher risk for breast cancer. And, because pathologists receive a high number of breast biopsies to diagnose, physicians and clinical laboratories already have collaborative experience working with genetic mutations supported by ample published evidence outlining their relationship with cancer.

Now, a global research study is adding 72 more mutations to the list of mutations already known to be associated with breast cancer.

In coming years, physicians and anatomic pathologists can expect to use the knowledge of these 72 genetic mutations when diagnosing breast cancer and possibly other types of cancers in which these mutations may be involved.

New Precision Medicine Tools to Improve Breast Cancer Survival

Combining the efforts of more than 550 researchers across 300 institutions and six continents, the OncoArray Consortium analyzed the DNA of nearly 300,000 blood samples. The analysis included samples of both estrogen receptor (ER-positive and ER-negative) cases.

Taken from a study published in the British Journal of Cancer, the graph above illustrates “proportions of familial risk of breast cancer explained by hereditary variants.” It is expected that anatomic pathologists will eventually incorporate these genetic variants into diagnostic test for breast and other cancers. (Graphic copyright: British Journal of Cancer.)

The results of their research were published in two separate studies: one in the scientific journal Nature and the other in Nature Genetics. The studies outlined 72 newly isolated genetic mutations that might help quantify the risk of a woman developing breast cancer in her lifetime.

Among the 72 mutations, seven genes were specifically associated with ER-negative cases. ER-negative breast cancer often fails to respond to hormone therapy. Thus, this discovery could be crucial to developing and administering precision medicine therapies tailored to specific patients’ physiologies and conditions. Treatments that improve patient outcomes and overall survival rates in ER-negative and ER-positive breast cancers.

Genetics Could Help Clinical Laboratories Wage War on All Cancers

According to data published by the Centers for Disease Control and Prevention (CDC), breast cancer is the most common form of cancer among women of all races. It’s the second-leading cause of all cancer deaths among most races and first among Hispanic women.

In the past, it was estimated that 5-10% of breast cancers were inherited through the passing of abnormal genes. However, Lisa Schlager, Vice President of community affairs and public policy for FORCE (Facing Our Risk of Cancer Empowered), told CNN, “This new information may mean that that estimate is low.” FORCE is a national nonprofit organization dedicated to fighting hereditary breast, ovarian, and related cancers.

Schlager calls upon health systems to “embrace the ability to use genetic information to tailor healthcare by providing affordable access to the needed screening and preventive interventions.” As precision therapy and genetic analysis continue to shape the way patients are treated, medical laboratories will play a significant role in providing the information powering these innovative approaches.

Furthermore, medical laboratories might leverage the same methods used by researchers to assess risk factors and identify genetic mutations and markers associated with other cancers. Douglas Easton, PhD, Director of the Centre for Cancer Genetic Epidemiology within the Department of Public Health and Primary Care at the University of Cambridge, and leader of the OncoArray Consortium investigation, explained to CNN that Illumina’s Infinium OncoArray is not limited to breast cancer, but is designed to work with other cancers, including:

·       colorectal;

·       ovarian; and,

·       prostate cancers.

Identifying Women at Increased Risk for Breast Cancer

Peter Kraft, PhD, Professor of Epidemiology at Harvard’s T.H. Chan School of Public Health, and a study author, told CNN, “Taken together, these risk variants may identify a small proportion of women who are at three-times increased risk of breast cancer.”

Kraft notes that samples were sourced from women of primarily European ancestry. Further study of other ethnic populations could lead to yet more mutations and indicators for cancers more common outside of the European region.

Research authors also highlight the importance of continued standard screening, such as mammograms. However, they suggest that genetic mutations, such as those found in the OncoArray study, might be used to highlight high-risk individuals and screen sooner, or conduct more in-depth genetic analyses, to catch potential cancer cases earlier and improve outcomes.

“Many women are offered mammogram screening when they are middle-aged,” Georgia Chenevix-Trench, PhD, co-author of the Nature Genetics study and researcher at the QIMR Berghofer Medical Research Institute in Australia, told LabRoots. “But if we know a woman has genetic markers that place her at higher risk of breast cancer, we can recommend more intensive screening at a younger age.”

Anatomic pathologists and clinical laboratories can use these new insights to offer increased options for oncologists and physicians on the front lines of the battle against cancer. While the list of genetic mutations related to cancer is far from complete, each added mutation holds the potential to power a new treatment, improve early detection rates, and improve survival rates of this global killer.

Human Antibodies in Medical Laboratory May Be Key to Immunity and Preventing Diseases Such as Influenza A

Scientists with Francis Crick Institute and Ragon Institute have successfully created human antibodies in vitro that can be made to recognize specific antigens in the human body; Could lead to new treatments for cancer and other infectious diseases

It’s been long-recognized that the ability to design human antibodies customized to recognize specific antigens could be a game-changer in the diagnosis and treatment of many diseases. It would enable the creation of useful new clinical laboratory tests, vaccines, and similar therapeutic modalities.

Now an international research team has published the findings of its novel technique that was developed to generate human antibodies in vitro. The research was conducted at the Ragon Institute of Massachusetts General Hospital (MGH), Massachusetts Institute of Technology (MIT), Harvard, and the Francis Crick Institute in London.

Antibodies and antigens are used in a large number of clinical laboratory and anatomic pathology tests and assays. In many cases, animal antibodies/antigens are used in test kits because they attract and bind to specific human antibodies/antigens that are biomarkers for diagnoses. Thus, as this technology is validated and further developed, it could be the source of useful biomarkers for lab tests as well as for vaccines.

Antibodies—also referred to as immunoglobulins—are made by the body’s B-lymphocytes (B cells) in response to antigens, such as bacteria, viruses, or other harmful substances. Each antibody has a special bearing on a particular antigen. For example, the human immunodeficiency virus (HIV) antibody and HIV antigen (p24) test screens and diagnoses people for HIV infection, explained LabTestsOnline.

Many medical laboratory tests use animal antibodies and antigens. But what if human antibodies could be generated and stimulated to recognize specific human antigens? That’s what the researchers believe they have done, according to a press release.

The Ragon Institute at MGH, MIT, and Harvard (above) was established in 2009 to find an HIV vaccine and to be a worldwide leader in the study of immunology. The Francis Crick Institute, formed in 2015, is a biomedical research institute using biology to understand health and disease. (Photo copyright: The Ragon Institute.)

The researchers know the novel technique they developed for generating human antibodies in vitro needs further development and validation. If this happens, the technique could one day be the source of useful biomarkers for medical lab tests, and may be a way to prevent infectious diseases.

“Specifically, it should allow the production of these antibodies within a shorter time frame in vitro and without the need for vaccination or blood/serum donation from recently infected or vaccinated individuals,” said Facundo D. Batista, PhD, in the press release. Batista is Principle Investigator with the Ragon Institute and led the research teams. “In addition, our method offers the potential to accelerate the development of new vaccines by allowing the efficient evaluation of candidate target antigens.”

Researchers Aim to Make Human Antibodies in Medical Laboratory

This international team of researchers sought to replicate in the lab—using patient blood samples—a natural human process for creation of antibodies from B cells. This is the process they wished to replicate:

·       Antibodies are made by the body’s B cells;

·       An antigen molecule is recognized by a B cell;

·       Plasma cells (able to secrete antibodies) develop;

·       An antibody binds to a particular antigen to fight an infection.

“B lymphocytes (B cells) play a critical role in adaptive immunity, providing protection from pathogens through the production of specific antibodies. B cells recognize and respond to pathogen-derived antigens through surface B cell receptors,” the researchers wrote in The Journal of Experimental Medicine (JEM).

Nanoparticles Key to the Approach

But finding an exact antigen is only one part of the B cell’s job. In the lab, B cells also need a trigger that enables them to grow and develop into plasma cells, which are key to fighting disease, the researchers noted.

“The in vitro activation of B cells in an antigen-dependent manner is difficult to achieve,” the authors stated in the JEM. “To overcome limitations, we developed a novel in vitro strategy to stimulate human B cells with streptavidin nanoparticles conjugated to both CpG and antigen. B cells producing antigen-specific antibodies were identified, quantified, and characterized to determine the antibody repertoire.”

According to the press release, “CpG oligonucleotides internalize into B cells that recognize the specific antigen.”

The statement, which garnered worldwide attention, noted the following steps taken by the researchers:

·       B cells from patient blood samples were isolated;

·       Then, they were treated with tiny nanoparticles coated with both CpG oligonucleotides and the right antigen;

·       These DNA molecules are unique, because they can activate toll-like receptor 9 (TLR9);

·       TLR9 develops into antibody-secreting plasma cells.

Results: Antibodies for Tetanus, Influenza, HIV

This method, according to the scientists, could be used in further research to develop antibodies to treat infectious diseases and cancer.

According to The Times of India,

·       “The team successfully demonstrated their approach using various bacterial and viral antigens, including the tetanus toxoid and proteins from several strains of influenza A;

·       “In each case, the researchers were able to produce specific, high-affinity antibodies in just a few days. Some of the anti-influenza antibodies generated by the technique recognized multiple strains of the virus and were able to neutralize its ability to infect cells;

·       “The procedure does not depend on the donors having been previously exposed to any of these antigens through vaccination or infection; and,

·       “Researchers were able to generate anti-HIV antibodies from B cells isolated from HIV-free patients.”

Research Suggests More Possibilities

While this highly scientific study may not be on the radar of most anatomic pathologists and medical laboratory leaders at the moment, it holds enormous promise to produce cures for infectious disease and more effective cancer treatments. This research project also demonstrates how new techniques using antibodies have the potential to create an entirely new generation of clinical laboratory assays that improve diagnostic accuracy and better inform physicians when they consider the most appropriate therapies for their patients.

Medical Laboratories Find Opportunities as Digital Therapeutics Companies Leverage Mobile Applications for Treatment of Chronic Conditions

Digital Therapeutics combined with clinical laboratory oversight testing could help chronic disease patients avoid surgeries and expensive drug therapies

One area of technology that has fundamentally changed the healthcare industry involves mobile devices. But those early “wellness” tools have evolved. Today’s modern mobile health devices feature software applications (apps) designed to remotely treat chronic conditions by helping modify patient behavior, as well as monitoring drug intake and physical condition biomarkers. These devices are dubbed “Digital Therapeutics,” and they present opportunities for anatomic pathology groups and clinical laboratories.

For if mobile apps are going to be used to monitor patients’ adherence to therapy—including prescription drugs—there will be a need for clinical laboratory tests that work in harmony with these apps. Otherwise, how will providers and insurers know for certain patients’ biomarkers have improved or regressed?

Massive Investments in Digital Therapeutics Companies

Today’s digital therapeutics (AKA, software for drugs) can be tailor to specific treatments of chronic conditions, such as:

·       diabetes mellitus;

·       cardiovascular disease;

·       hypertension; and,

·       chronic obstructive pulmonary disease (COPD).

Forbes states that the “future of healthcare will be app based.” That seem likely given the massive influx of capital being directed at the mobile healthcare industry.

The graphic above is taken from a 2015 report by PricewaterhouseCoopers Health Research Institute  (PwC), which sourced the data from the 2014 clinician workforce and consumer surveys. Since then, the demand for mHealth products has increased exponentially. Today’s digital therapeutics market includes clinical laboratory and pathology group treatments and drug therapies. (Graphic copyright: PwC.)

The global digital therapeutics market is projected to grow to about $9 billion by 2025. That’s up from $1.7 billion last year, according to a report by Grand View Research. Driving the popularity of digital therapeutics are the benefits it affords patients, explained the report’s summary. They include:

·       Continuous monitoring of vital signs;

·       Medication management; and,

·       Current healthcare reminders.

This is where pathologists and clinical laboratories come in. The medical laboratory can be the source for baseline blood tests before apps are used. And then, ongoing testing can determine if patients are taking drugs according to treatment guidelines and making the appropriate lifestyle changes.

Start-ups Raise Millions, Define Digital Therapeutics Space

One unique aspect of digital therapeutics is its ability to promote health improvements through behavioral changes alone. And millions are being invested in the concept.

For example, Virta Health Corp. raised $37 million in funding for an app that coaches diabetics on a diet to reverse their condition without drugs or surgery, according to MIT Technology Review.

“[Digital therapeutics] is still a fluid space that everyone is trying to categorize,” Peter Hames, co-founder and Chief Executive Officer of Big Health noted in the MIT Technology Review article. Among other programs, Big Health developed Sleepio, a sleep improvement program or insomnia app. Hames says most apps fall into two categories: “medication augmentation” or “medication replacement.”

Omada Health secured $127 million to conduct a clinical trial with Humana that investigates prediabetes, noted Forbes.

The study findings, which appeared in the Journal of Aging and Health, suggest that Omada Health’s digital behavior change program can help people to reduce chronic disease risk, noted a Humana news release.

The study involved Humana Medicare Advantage insurance members, who were enrolled in Omada Health’s Diabetes Prevention Program. The app enabled them to partake in online courses, use wireless scales, and tap other digital health tools as they worked to improve health and reduce risk of type 2 diabetes. Human coaches also were accessible.

“Few efforts have explored the feasibility and effectiveness of using technology to deliver diabetes prevention programs specifically for older adults,” the study researchers wrote.

According to the researchers:

·       501 people with average weight of 208 pounds participated;

·       Hour-long lessons were made available and expected to be completed by smartphone, laptop, or tablet;

·       Coaches monitored the information participants provided and their requests for counseling;

·       92% of participants completed at least nine of the 16 core online courses, which focused on topics such as changing food habits and increasing physical activities;

·       People lost 7.5% of body weight after 12 months, or 13 to 14 lbs.;

·       A subsample (69 individuals) who had lab tests performed improved glucose control as evidenced by a -0.14% reduction in glycosylated hemoglobin, and a decrease of -7.08 mg/dL in total cholesterol.

“These results support the clinical validity of the program with Medicare-eligible, at risk older adults. They are added evidence that chronic disease risk reduction is achievable through a variety of modalities, including digital-based programs with human coaching,” the researchers noted.

And because digital therapeutics amasses data that can be leveraged, Omada Health’s program acts as a “continuous learning system,” Sean Duffy, Omada Health’s co-founder and Chief Executive Officer, noted in Undark.

App Tracks People After Heart Attack

Johns Hopkins Medicine’s Corrie Health app is aimed at helping patients recover from heart attacks. A study at Johns Hopkins Bayview Medical Center in Baltimore explored the effectiveness of app-enabled information and resources made available to patients early in the heart attack recovery process, according to Corrie Health’s Website.

Results from the clinical study of 50 patients show no one was readmitted to hospital in the first 30 days, Undark reported.

“We can actually enroll patients who are six or seven hours out of having a stent placed in the ICU. We’re giving [the Corrie Health app] to patients when they have the time to spend watching the videos and asking questions about their medications … We’re getting them to buy-in and learn the skills while they care the most,” Francoise Marvel, MD, an internist affiliated with Johns Hopkins Bayview Medical Center, told Undark.

A Role for Medical Laboratories

So, is there a role for medical laboratories where digital therapeutics are being used? We think so. Pathologists and lab leaders may even want to reach out to venture capitalists working on mobile apps that combine adherence to therapies with medical lab tests.

As our population ages and the shortage of physicians becomes more evident, digital therapeutics may be a smart way to address select patient needs in a quality and cost-effective manner.

Decline in Imaging Utilization Could Be Linked to Changes in Policies and Funding for Diagnostics; Could Something Similar Happen with Anatomic Pathology?

New study analyzes the dramatic decline in the utilization of imaging diagnostics between 2008 and 2014 and suggests that reductions in imaging use could be the result of changes in federal policy, increased deductibles, and cost-cutting focuses

Anatomic pathologists have experienced sustained cuts to reimbursements for both technical component and professional component services during the past eight to 10 years. But what has not happened to pathology is a 33% decline in the volume of biopsies referred to diagnosis. Yet that is what some studies say has happened to imaging reimbursement since 2006.

Using Medicare data for Part B imaging procedures covering the years 2001 to 2014, researchers at a major university identified that, beginning in 2006, the total reimbursement for imaging procedures declined at a steady rate throughout the following eight years covered by the study. It is unclear what implications the finding of this study of imaging utilization might predict for the utilization of advance anatomic pathology services.

Routine Use of Imaging in Diagnostics is Slowing Down

The research into imaging utilization was conducted at Thomas Jefferson University and published in the journal Health Affairs. Led by David C. Levin, MD, Emeritus Professor and former Chair of the Department of Radiology at Thomas Jefferson University Hospital, the researchers examined imaging data from Medicare Part B (2001-2014) to determine the reason and rate of “slowdown” in routine use of imaging in diagnostics.

The researchers calculated utilization rates for “advanced” imaging modalities and component relative value unit (RVU) rates for all imaging modalities. They determined that trends in imaging rates and RVU rates rose between 2000 and 2008, but then sharply declined from 2008 to 2014. The researchers theorized that the reduction might have been due to changes in federal policy, increasing deductibles, and focus on cost-cutting by hospitals and healthcare providers.

Levin, along with Thomas Jefferson University associates Vijay M. Rao, MD, FACR, current Chair of Radiology, and Laurence Parker, PhD, Associate Professor of Radiology; and University of Wisconsin-Madison statistics Professor Charles D. Palit, PhD, argue that the decrease in imaging orders might reduce diagnostic costs, but also could negatively impact surgical pathologists, radiologists, medical researchers, and patients themselves.

In a Modern Healthcare article, Levin states that the reduction in utilization of imaging and radiology could be a slippery slope leading to decreased access to life-saving diagnostic tools that could leave patients “not getting the scans they probably need.”

What’s Fueling the Multi-Year Decline in Utilization of Imaging and Radiology?

In the Journal of American College Radiology, Levin, Rao, and Parker, attempt to “assess the recent trends in Medicare reimbursements to radiologists, cardiologists, and other physicians for non-invasive diagnostic imaging (NDI).”

Using data acquired from Medicare part B databases, the authors reported that total reimbursements for NDI peaked at $11.9 billion in 2006, but saw a steep decline of 33% to just over $8 billion in 2015. They attribute some of this decline as a result of the Deficit Reduction Act of 2005, which went into effect in 2007, as well as other cuts to NDI reimbursement funding. Reimbursement to radiologists, according to Levin et al, dropped by more than 19.5%, and reimbursement to cardiologists dropped nearly 45% between 2006 and 2015.

Surgical pathologists may see parallels in the total reimbursement for imaging during the years 2002-2015 compared to pathology technical component and professional component reimbursement during those same years. Taken from the Thomas Jefferson University study, the graphic above shows “total Part B payments for non-invasive diagnostic imaging to all physicians under the Medicare Physician Fee Schedule, 2002 to 2015. Vertical axis shows billions of dollars. The abrupt decline in 2007 was due to the Deficit Reduction Act. The declines in 2009, 2010, and 2011 were due largely to code bundling in, respectively, transthoracic echocardiography, radionuclide myocardial perfusion imaging, and CT of the abdomen and pelvis.” (Caption and image copyright: Thomas Jefferson University.)

In different Journal of American College Radiology article, Levin and Rao outline their concerns over another suspected cause for the decline in imaging utilization—the American Board of Internal Medicine Foundation (ABIMF) Choosing Wisely initiative.

According to Levin and Rao, the Choosing Wisely initiative was intended “to reduce the use of tests and treatments that were felt to be overused or often unnecessary.” Imaging examinations were included in the list of tests that were deemed to be “of limited value” in many situations. Levin and Rao suggested that there might have been a need to curtail testing pushed by payers, policymakers, and physicians at the time, but that the Choosing Wisely initiative could have added to a decline in imaging testing spurred on by the confusion physicians felt when attempting to access unclear scenarios and recommendations for the 124 imaging tests listed.

Imaging Decline Could Have Unintended Consequences for Providers and Patients 

In a Radiology Business article, Levin outlined some of the unintended consequences facing healthcare due to the reduction in imaging utilization. He states that “private imaging facilities are starting to close down” and “MRI and other advanced imaging exams are beginning to shift into hospital outpatient facilities.” He predicts that the shift from private facilities to hospital facilities could cause imaging costs to increase for customers and healthcare providers.

Levin suggests that Medicare could “raise the fees a little and make the private offices a little more viable.” The profit margins, Levin argues, “are so low right now that you basically can’t run a business.” Medicare as a program might be seeing huge savings, Levin notes in several articles, but physicians, laboratories, and patients are feeling the pinch as a result.

In an interview with Physicians Practice, Rao echoed Levin’s concerns. “Policy makers lack understanding of the value of imaging and spectrum of the services provided by radiologists,” he declared. “On an institutional level, under the new payment models, radiology is transitioning to a cost center and radiologists often don’t have a seat at the table.”

Rao points out that this devaluing of radiologists’ work affects not only healthcare facilities, but patients themselves. Radiologists provide “major contributions to patient care by making accurate diagnoses, and doing minimally invasive treatments given many technological advances leading to appropriate management and improved outcomes,” he argues. How long before Pathology follows a similar track?

Balancing Cost and Quality in Testing Without Sacrificing Patient Needs

The fear seems to be that the push to lower costs by eliminating unnecessary imaging is inhibiting radiologists and diagnosticians from providing necessary imaging for patients. And that delaying diagnoses affects the ability of healthcare providers to provide adequate and timely patient care. Rao suggests, however, that physicians’ use of medical imaging could simply be evolving.

“There were other factors that also helped limit the rapid growth, such as greater attention by physicians to practice guidelines, concerns about radiation exposure to patients, and the Great Recession of 2007 to 2009,” Rao noted in a Thomas Jefferson University news release. “However, we expect that additional changes, such as the advent of lung cancer and other screening programs, and the use of computerized clinical decision support, will continue to promote and support appropriate use of imaging technology.”

The drive to reduce healthcare expenditures should not be dismissed. We may soon see parallels in the rise and fall of imaging utilization for genetic testing, surgical pathology, and other new and expensive clinical laboratory technologies as policymakers attempt to balance increased spending against the clinical value of these diagnostic tools.

Medicare Officials Back Off a Proposal to Make Hospital Inspection Reports Publicly Available; CLIA Inspections of Medical Laboratories Are Still Not Public

The Joint Commission opposed the Medicare proposal, and patient advocate groups say rescinding it is a setback for hospital  transparency

Powerful interests arrayed against greater transparency in the performance of hospitals, physicians, and medical laboratories have stopped a proposed Medicare program that would have allowed the public to see the results of hospital inspections.

Stopped in its tracks was an effort by the Centers for Medicare and Medicaid Services (CMS) to make hospital accreditation inspection reports available for public viewing. Opposition to this program led CMS to withdraw its plan for heightened transparency.

CMS originally called the proposal “groundbreaking” in a National Public Radio (NPR) article. That’s because it would have enabled consumers to view reports that private accreditation organizations, such as The Joint Commission, complete after each inspection. Inspection reports contain information on errors and problems found during hospital surveys. CMS’ push for more transparency in hospital inspections is consistent with the healthcare industry’s trend toward open sharing of healthcare quality, price, and other data.

“We are proposing changes relating to transparency of accrediting organizations survey reports and plans of correction of providers and suppliers,” CMS officials wrote in a proposed rule published on April 28.

CMS Pulls Back Proposal to Make Hospital Survey Reports Public

But it was not to be. After receiving comments, CMS officials stated in early August that the agency had pulled back the proposal.

“CMS is committed to ensuring that patients have the ability to review the findings used to determine that a facility meets the health and safety standards required for Medicare participation. However, we believe further review, consideration, and refinement of this proposal is necessary to ensure that CMS establishes requirements, consistent with our statutory authority, that will inform patients and continue to support high quality care,” noted a CMS fact sheet.

Agencies Find Problems in Hospitals That Accreditors Do Not, CMS Declares

It’s against federal law for CMS to release data related to hospital inspections, Becker’s Hospital Review reported. And, as part of the Clinical Laboratory Improvement Amendments (CLIA), clinical laboratories must participate in inspections to ensure they qualify for Medicare and Medicaid payments. However, the inspection reports of the nation’s medical laboratories are not made public.

So, what motivated CMS to make healthcare organizations’ inspection information public? CMS noted that private accreditation organizations miss serious provider problems that state inspectors find in follow-up visits to hospitals, ProPublica explained.

In fact, state agency reviews of 103 hospitals in 2014 found 41 serious deficiencies, including 39 missed by the accreditors, noted the NPR article.

“Right now, the public has very little information about the places where they’re putting their life on the line, and that’s just not acceptable. If [they are] a good place, what are they afraid of?” Rosemary Gibson, Senior Advisor at The Hastings Center, stated in the NPR article.

Reaction from Accreditors and Consumer Groups Differs

The Joint Commission opposed the CMS proposal. And, now, patient safety advocacy groups are disappointed about the decision by Medicare officials to rescind the proposed program.

“We believe the proposal will have significant detrimental consequences on our nation’s ability to continually improve the delivery of healthcare services,” stated Mark Chassin, MD, FACP, MPP, MPH, Joint Commission President and Chief Executive Officer, in a June letter to CMS published partially in an HCPro blog post.

HCPro, a firm that aids organizations in accreditation, credentialing, and other needs, noted the following Joint Commission concerns about publicly shared survey reports in the blog post:

  • Providers may be less likely to be open about opportunities for improvement;
  • Accreditors could struggle to create new standards;
  • The number of non-accredited facilities may increase;
  • Accreditation may be devalued; and,
  • Costs to providers and accreditors would likely rise.

The Center for Improvement in Healthcare Quality (CIHQ), another accreditation option for hospitals, also expressed concerns with the CMS proposal, according to the ProPublica report.

“Knowing that survey [inspection] reports are public knowledge will only incentivize hospitals and other healthcare entities to go back to the days of ‘hiding’ quality of care issues from accreditors, rather than working with us to improve the quality and safety of care rendered to patients,” CIHQ advised in the ProPublica article.

The Leapfrog Group, which bills itself as an advocate of hospital transparency, called the reversed proposal “a disappointing setback for healthcare transparency.”

In a statement, Leah Binder, President and Chief Executive Officer of The Leapfrog Group, noted, “We are disappointed to learn that the agency that runs Medicare (CMS) has reversed course on its proposal to require private accrediting organizations, such as the Joint Commission, to publicly release reports of problems they found in hospitals and other healthcare facilities. The public deserves full transparency on how the healthcare industry performs.”

Clearly the public is calling for increased transparency in healthcare. As are many organizations and industry journals, such as the Association of Health Care Journalists (AHCJ), which presented a national award to Ellen Gabler, an investigative reporter for the Milwaukee Journal Sentinel, for her work covering weaknesses in inspections for clinical laboratories. (See Dark Daily, “Journalists Take Home Top National Awards for Their Work Covering Theranos and the Clinical Laboratory Industry,” May 16, 2016.)

Some Accreditation Information Available Online

So, for the time being, it appears that what is found during hospital inspections will stay within the inspection report and will not become available to the general public. However, with consumers expecting greater transparency and higher levels of service in all aspects of healthcare, the interest in public access to the quality performance of hospitals, physicians, clinical laboratories, and anatomic pathology groups will only increase.

Meanwhile, for patients interested in existing resources about provider quality, The Joint Commission has an online “find a gold star healthcare organization” quality check. Also, the American College of Surgeons publishes an online search for accredited facilities. And, the Centers for Disease Control and Prevention (CDC) offers an online search for CLIA accredited labs.
