Strategists agree that big tech is disrupting healthcare,
so how will clinical laboratories and anatomic pathology groups serve virtual
healthcare customers?
Visionary XPRIZE founder Peter Diamandis, MD, sees big tech as “the doctor of the future.” In an interview with Fast Company promoting his new book, “The Future Is Faster Than You Think,” Diamandis, who is the Executive Chairman of the XPRIZE Foundation, said that the healthcare industry is “phenomenally broken” and that Apple, Amazon, and Google could do “a thousandfold” better job.
Diamandis, who also founded Singularity University, a global learning and innovation community that uses exponential technologies to tackle worldwide challenges, according to its website, said, “We’re going to see Apple and Amazon and Google and all the data-driven companies that are in our homes right now become our healthcare providers.”
If this prediction becomes reality, it will bring significant changes in the traditional ways that consumers and patients have selected providers and access healthcare services. In turn, this will require all clinical laboratories and pathology groups to develop business strategies in response to these developments.
Amazon Arrives in Healthcare Markets
Several widely-publicized business initiatives by Amazon, Google, and Apple substantiate these predictions. According to an Amazon blog, healthcare insurers, providers, and pharmacy benefit managers are already operating HIPAA-eligible Amazon Alexa for:
Alexa also enables HIPAA-compliant blood glucose updates as part of the Livongo for Diabetes program. “Our members now have the ability to hear their last blood glucose check by simply asking Alexa,” said Jennifer Schneider, MD, President of Livongo, a digital health company, in a news release.
And Cigna’s “Answers By Cigna” Alexa “skill” gives members who install the option responses to 150 commonly asked health insurance questions, explained a Cigna news release.
“Google plans to disrupt healthcare and use data and artificial intelligence,” Toby Cosgrove, Executive Advisor to the Google Cloud team and former Cleveland Clinic President, told B2B information platform PYMNTs.com.
PYMNTs speculated that Google, which recently acquired Fitbit, could be aiming at connecting consumers’ Fitbit fitness watch data with their electronic health records (EHRs).
“Ultimately what’s best is human and AI collaboratively,” Peter Diamandis, MD, founder of XPRIZE Foundation and Singularity University told Fast Company. “But I think for reading x-rays, MRIs, CT scans, genome data, and so forth, that once we put human ego aside, machine learning is a much better way to do that.” (Photo copyright: SALT.)
Apple Works with Insurers, Integrating Health Data
The Apple Watch health app also enables people to access medical laboratory test results and vaccination records, and “sync up” information with some hospitals, Business Insider explained.
Virtual Care, a Payer Priority: Survey
Should healthcare providers feel threatened by the tech giants? Not necessarily. However, employers and payers surveyed by the National Business Group on Health (NBGH), an employer advocacy organization, said they want to see more virtual care solutions, a news release stated.
“One of the challenges employers face in managing their healthcare costs is that healthcare is delivered locally, and change is not scalable. It’s a market-by-market effort,” said Brian Marcotte, President and CEO of the NBGH, in the news release. “Employers are turning to market-specific solutions to drive meaningful changes in the healthcare delivery system.
“Virtual care solutions bring healthcare to the consumer
rather than the consumer to healthcare,” Marcotte continue. “They continue to
gain momentum as employers seek different ways to deliver cost effective,
quality healthcare while improving access and the consumer experience.”
“In AI, there are three trends to watch,” said health strategist Ted Schwab (above) while speaking at the 2019 Executive War College. “The first major AI trend will affect clinical laboratories and pathologists. It involves how diagnosis will be done on the Internet and via telehealth. The second AI trend is care delivery, such as what we’ve seen with Amazon’s Alexa—you should know that Amazon’s business strategy is to disrupt healthcare. And the third AI trend involves biological engineering,” he concluded. (Photo copyright: Dark Daily.)
“If you use Google in the United States to check symptoms,
you’ll get five-million to 11-million hits,” Schwab told The Dark Report.
“Clearly, there’s plenty of talk about symptom checkers, and if you go online
now, you’ll find 350 different electronic applications that will give you
medical advice—meaning you’ll get a diagnosis over the internet. These
applications are winding their way somewhere through the regulatory process.
“The FDA just released a report saying it plans to regulate
internet doctors, not telehealth doctors and not virtual doctors,” he
continued. “Instead, they’re going to regulate machines. This news is
significant because, today, within an hour of receiving emergency care, 45% of
Americans have googled their condition, so the cat is out of the bag as it
pertains to us going online for our medical care.”
Be Proactive, Not Reactive, Health Leaders Say
Healthcare leaders need to work on improving access to primary care, instead of becoming defensive or reactive to tech companies, several healthcare CEOs told Becker’s Hospital Review.
Clinical laboratory leaders are advised to keep an eye on
these virtual healthcare trends and be open to assisting doctors engaged in
telehealth services and online diagnostic activities.
The scientist also employed machine learning “to gauge how easily accessible genes are for transcription” in research that could lead to new clinical laboratory diagnostic tests
Anatomic pathologists and clinical laboratories are of course familiar with the biological science of genomics, which, among other things, has been used to map the human genome. But did you know that a three-dimensional (3D) map of a genome has been created and that it is helping scientists understand how DNA regulates its organization—and why?
The achievement took place at St. Jude Children’s Research Hospital (St. Jude) in Memphis, Tenn. Scientists there created “the first 3D map of a mouse genome” to study “the way cells organize their genomes during development,” a St. Jude news release noted.
Some experts predict that this new approach to understanding how changes happen in a genome could eventually provide new insights that anatomic pathologists and clinical laboratory scientists could find useful when working with physicians to diagnose patients and using the test results to identify the most appropriate therapy for those patients.
In addition to 3D modeling, the researchers applied machine learning to data from multiple sources to see how the organization of the genome changed at different times during development. “The changes are not random, but part of the developmental program of cells,” Dyer said in the news release.
The St. Jude study focused on the rod cells in a mouse retina. That may seem like a narrow scope, but there are more than 8,000 genes involved in retinal development in mice, during which those genes are either turned on or off.
To see what was happening among the cells, the researchers used HI-C analysis, an aspect of ultra-deep chromosome conformation capture, in situ. They found that the loops in the DNA bring together regions of the genome, allowing them to interact in specific ways.
Until this study, how those interactions took place was a
mystery.
“Understanding the way cells organize their genomes during development will help us to understand their ability to respond to stress, injury and disease,”Michael Dyer, PhD (above), Chair of St. Jude’s Developmental Neurobiology Department, co-leader of the Developmental Biology and Solid Tumor Program, and Investigator at Howard Hughes Medical Institute (HHMI), said in the news release. (Photo copyright: St. Jude Children’s Research Hospital.)
The scientists also discovered there were DNA promoters, which encourage gene expression, and also DNA enhancers that increase the likelihood gene expression will occur.
“The research also included the first report of a powerful regulator of gene expression, a super enhancer, that worked in a specific cell at a specific stage of development,” the news release states. “The finding is important because the super enhancers can be hijacked in developmental cancers of the brain and other organs.”
St. Jude goes on to state, “In this study, the scientists determined that when a core regulatory circuit super-enhancer for the VSX2 gene was deleted, an entire class of neurons (bipolar neurons) was eliminated. No other defects were identified. Deletion of the VSX2 gene causes many more defects in retinal development, so the super-enhancer is highly specific to bipolar neurons.”
The St. Jude researchers developed a genetic mouse model of
the defect that scientists are using to study neural circuits in the retina,
the news release states.

DNA Loops May Matter to Pathology Sooner Rather than
Later
Previous researcher studies primarily used genomic sequencing technology to locate and investigate alterations in genes that lead to disease. In the St. Jude study, the researchers examined how DNA is packaged. If the DNA of a single cell could be stretched out, it would be more than six feet long. To fit into the nucleus of a cell, DNA is looped and bundled into a microscopic package. The St. Jude scientists determined that how these loops are organized regulates how the cell functions and develops.
Scientists around the world will continue studying how the loops in DNA impact gene regulation and how that affects the gene’s response to disease. At St. Jude Children’s Research Hospital, Dyer and his colleagues “used the same approach to create a 3D genomic map of the mouse cerebellum, a brain structure where medulloblastoma can develop. Medulloblastoma is the most common malignant pediatric brain tumor,” noted the St. Jude’s news release.
In addition to providing an understanding of how genes
function, these 3D studies are providing valuable insight into how some
diseases develop and mature. While nascent research such as this may not impact
pathologists and clinical laboratories at the moment, it’s not a stretch to
think that this work may lead to greater understanding of the pathology of
diseases in the near future.
Experts say Amazon could be planning a roll-out of healthcare services to its Prime members and others
Clinical laboratory leaders will want to note that the Telehealth and home healthcare industries have expanded with the launch of Amazon Care, a virtual medical clinic and home care services program from global retailer Amazon.com, Inc. (NASDAQ:AMZN).
Amazon is piloting Amazon Care as a benefit for its 53,000
Seattle-area employees and their families, according to published reports. Could
this indicate the world’s largest online retailer is moving into the primary
care space? If so, clinical laboratory leaders will want to follow this
development closely, because the program will need clinical laboratory support.
Amazon has successfully disrupted multiple industries in its
corporate life and some experts speculate Amazon may be using its own employees
to design a new medical delivery model for national roll-out.
The S&P report goes on to state, “In as little as five years, the Seattle-based e-commerce company could interlink its system of capabilities and assets to launch various healthcare products, insurance plans, virtual care services, and digital health monitoring to a broader population. The rollout would be part of a larger plan by Amazon to deliver convenient, cost-effective access to care and medications across the U.S., likely tied to Amazon’s Prime membership program, according to experts.”
Modern Healthcare reported that Amazon Care services include telemedicine and home visits to employees enrolled in an Amazon health insurance plan.
Experts contacted by S&P Global Market Intelligence
suggest Amazon:
Plans a “suite of customized health plans and
services for businesses and consumers;”
May offer health services to its five million
seller business and more than 100 million Amazon Prime members; and
Sees healthcare as a growing market and wants
greater involvement in it.
How Amazon Care Works
Amazon Care offers online, virtual care through a
downloadable mobile device application (app) as well as in-person home care for
certain medical needs, such as:
Colds, allergies, infections, and minor injury;
Preventative consults, vaccines, and lab tests;
Sexual health services; and
General health inquiries.
Becker’s Hospital Review reported that once a participant downloads the Amazon Care app to a smartphone or tablet and signs up for the program, he or she can:
Communicate with healthcare providers via text
or video;
Plan personal visits if needed;
Set payment methods in their user profile; and
Receive a “potential diagnosis” and treatment
plan.
The graphic above is taken from the S&P Global Market Intelligence report, which states, “Amazon is one of several tech firms vying for a share of the healthcare market where national spending is expected to reach $6.0 trillion by 2027, up from $3.6 trillion in 2018, according to the Centers for Medicare and Medicaid Services.” (Graphic copyright: S&P Global Market Intelligence.)
“The service eliminates travel and wait time, connecting employees and their family members to a physician or nurse practitioner through live chat or voice,” an Amazon spokesperson told CNBC, “with the option for in-person follow-up services from a registered nurse ranging from immunizations to instant strep throat detection.”
The “mobile health nurse” may also collect clinical laboratory
specimens, the Verge
reported.
Amazon has partnered with Oasis Medical Group, a family primary care practice in Seattle, to provide healthcare services for Amazon Care patients.
Paving the Way to Amazon Care
The Healthcare Financial Management Association (HFMA) compares Amazon’s piloting of Amazon Care to similar healthcare projects that studied population health by first involving employee health plans.
HFMA’s analysis noted that Amazon Care is similar to Haven, a patient advocate organization based in Boston and New York that was created in 2018 by Amazon, JPMorgan Chase, and Berkshire Hathaway to lower healthcare costs and improve outcomes for participating companies.
Tech Crunch reported that in 2018 Amazon also purchased PillPack for nearly $1 billion and integrated its prescription delivery services into Amazon Care.
More recently, Amazon acquired Health Navigator and plans to bring those offerings to Amazon Care as well, CNBC reported. Founded in 2014, Health Navigator provides caregivers with symptom-checking tools that enable remote diagnoses.
Should Telemedicine Firms Be Nervous?
Dark Daily recently reported on Doctor on Demand’s launch of its own virtual healthcare telehealth platform called Synapse. The e-briefing also covered Doctor on Demand’s partnership with Humana (NYSE:HUM) to provide virtual primary care services to the insurer’s health plan members, including online doctor visits at no charge and standard medical laboratory tests for a $5 copayment.
So, should telemedicine firms be concerned about Amazon competing in their marketplace? Business Insider predicts Amazon will need time to beef up its medical resources to serve people online and in-person through Amazon Care.
But that’s the point of Amazon’s pilot, isn’t it? What comes
from it will be interesting to watch.
“Meanwhile, telemedicine firms can ink strategic
partnerships and strengthen their existing payer relationships to safeguard
against Amazon’s surge into the space,” Business Insider advised.
It remains to be seen how medical laboratory testing and reports
would fit into an expanded Amazon Care health network. Or, how clinical laboratories
will get “in-network” with Amazon Care, as it grows to serve customers beyond
Amazon’s employees.
As Dark Daily recently advised, medical laboratory leaders will want to ensure their lab’s inclusion in virtual care networks, which someday may include Amazon Care.
The software applications (apps) and hardware monitoring devices involved in digital therapeutics enable physicians and patients to target and alter specific behaviors that affect certain medical conditions, such as substance abuse or depression. Combined with or without drugs, digital therapeutics are achieving positive results, according to the United Kingdom’s PwC (PricewaterhouseCoopers) Health Research Institute (PwC HRI).
The report goes on to state that digital therapeutics “is
reshaping the landscape for new medicines, product reimbursement and regulatory
oversight … [and that] new data sharing processes and payment models will be
established to integrate these products into the broader treatment arsenal and
regulatory structure for drug and device approvals.
“Connected health services,” the report continues, “enabled by devices that transmit data or connect to the Internet, give additional visibility into care delivery and new ways to improve patient outcomes.”
Digital therapeutics combine apps and monitoring devices for
the management and treatment of medical conditions. While similar to customer
wellness apps, digital therapeutics focus on specific clinical outcomes.
The non-profit Digital Therapeutics Alliance says that, unlike common “wellness” apps, digital therapeutics “possess the unique ability to incorporate additional functionalities into a comprehensive portfolio of synchronous products and services. This includes potential integration with mobile health platforms; the provision of complementary diagnostic or adherence interventions; the ability to pair with devices, sensors, or wearables; the delivery of interventions remotely; and integration into electronic prescribing, dispensing, and medical record platforms.”
“Digital therapeutics are the next frontier,” Sai Jasti, Chief Data and Analytics Officer, GlaxoSmithKline (NYSE:GSK), told PwC HRI. “I think we will see a lot more collaboration between pharmaceutical and technology companies to drive this forward, ultimately to the benefit of patients.”
Digital Therapeutics That Already Have FDA Approval
Digital therapeutics and their connected devices are subject
to the approval process of the federal Food and Drug Administration (FDA), and
some have already received that coveted clearance:
reSET from Pear Therapeutics is a 90-day prescription digital therapeutic (PDT) for substance use disorder (SUD). The Boston-based company also worked with Sandoz Inc., a division of Novartis, to receive FDA approval for reSET-O, a PDT for treating individuals with Opioid Use Disorder (OUD).
“Digital technologies and data science have incredible potential to unlock the next chapter of medical innovation and to help individuals finally take control of their own health in a meaningful way,” said Richard Francis, Division Head and CEO, Sandoz, in a press release. “New digital therapeutics such as reSET-O also have the potential to fundamentally change how patients interact with their therapies and thus improve patient outcomes.”
Both reSET and reSET-O are software mobile apps that use cognitive behavioral therapy (CBT) to help individuals struggling with addictions.
“Nearly 50,000 drug overdose deaths involving opioids, including prescription pain medications and heroin, took place in the U.S. in 2017,” said Corey McCann, MD, PhD, President and CEO of Pear Therapeutics, in the press release following receiving FDA approval. “There is an urgent need for new and innovative therapeutics to address this public health epidemic. This groundbreaking decision by the FDA ushers in a new standard for treating patients with Opioid Use Disorder and it signals a new path for therapeutic software to be used in conjunction with pharmacotherapy to improve efficacy.”
Natural
Cycles is a birth control app created by a Sweden-based company of the same
name. It was approved by the FDA in 2018. This mobile app helps women track
their fertility to prevent unwanted pregnancies via the rhythm method. The app
analyzes data from past menstrual cycles and body temperature readings to
determine when the user is most fertile. On the days the user is most likely to
be ovulating, the app displays “Use Protection” on the mobile device’s screen.
“We know that women are more likely to use contraceptive methods when they have a variety of methods available to them, and the reality is that not every method is going to work for every woman,” Rebecca Simmons, PhD, Research Assistant Professor, Department of Obstetrics and Gynecology, University of Utah, told Health. “This is really exciting, in the sense that the more methods we have, the more likely it is that people can find something that works for them—and then can avoid unwanted pregnancy.”
Apple, headquartered in Cupertino, Calif., received FDA clearance in 2018 for an electrocardiogram (ECG) app for its Apple Watch Series 4 that allows users to take an ECG from their wrist to detect irregular heart rhythms and atrial fibrillation (AFIB).
“The role that technology plays in allowing patients to capture meaningful data about what’s happening with their heart—at the moment when it’s happening, like the functionality of an on-demand ECG—could be significant in new clinical care models and shared decision-making between people and their healthcare providers,” said Nancy Brown, CEO of the American Heart Association, in a press release.
Patients, Providers, and Big Pharma All Like Digital
Therapeutics
There is some evidence that patients and healthcare
providers are intrigued and willing to try digital therapeutics. In a PwC HRI survey,
more than 50% of respondents said they “would be somewhat or very likely to try
an FDA-approved app or online tool for treatment of a medical condition.”
The graphic above is taken from the PwC HRI 2019 annual report on digital therapeutics and connected care. It shows that “a majority of consumers surveyed are interested in FDA approved digital apps or online tools to treat their medical conditions.” (Graphic copyright: PwC HRI.)
Pharmaceutical companies also are interested in digital therapeutics. A 2018 PwC HRI survey found that 80% of pharmaceutical executives had plans to invest in digital therapeutics in the near future.
With precision medicine and pharmacogenetics, clinical laboratories
could play an essential role in supporting digital therapeutics in the future. But
to truly be competitive in this space and take advantage of the opportunity, medical
laboratories will need to increase their information technology and digital
capabilities.
Though medical laboratory testing is key to confirming sepsis, predictive analytics systems can identify early indications and alert caregivers, potentially saving lives
Medical laboratory testing has long been the key element in hospitals’ fight to reduce deaths caused by sepsis, a complication caused by the human body’s response to infection which can injure organs and turn fatal. But clinical laboratory testing takes time, particularly if infectious agents must be cultured in the microbiology lab. And sepsis acts so quickly, by the time the condition is diagnosed it is often too late to prevent the patient’s death.
One example is HCA Healthcare (NYSE:HCA), the for-profit corporation with 185 hospitals, 119 freestanding surgery centers, and approximately 2,000 sites of care in 21 US states and in the United Kingdom.
HCA employs an electronic information and alert system called SPOT (Sepsis Prediction and Optimization of Therapy), which is embedded in each hospital patient’s electronic health record (EHR).
SPOT receives clinical data in real time directly from
monitoring equipment at the patient’s bedside and uses predictive analytics to examine
the data, including medical laboratory test results. If the data indicate that
sepsis is present, SPOT alerts physicians and other caregivers.
With SPOT, HCA’s physicians have been detecting sepsis in
its earliest stages and saving lives. This lends support to the growing belief
that AI and machine learning can improve speed to diagnosis and diagnostic
accuracy, which Dark Daily has covered in multiple
e-briefings.
SPOT displays its data on screens that are monitored 24/7 (shown above). The clinical data include the patient’s vital signs as well as medical laboratory test results and nursing reports. HCA says the system has been used on about 2.5 million patients and has helped save up to 8,000 lives, Business Wire reported. (Photo copyright: HCA.)
Code Sepsis
HCA began developing the software in 2016. It was initially deployed in 2018 at TriStar Centennial Medical Center, HCA’s flagship hospital in Nashville,The Tennessean reported. It is now installed in most of the hospitals owned or operated by HCA.
Michael Nottidge, MD, is ICC Division Medical Director for Critical Care at HCA Healthcare Physician Services Group, and a critical care physician at TriStar Centennial. Nottidge told The Tennessean that unlike a heart attack or stroke, “sepsis begins quietly, then builds into a dangerous crescendo.”
Since its implementation, “[SPOT] has alerted clinicians to
a septic patient nearly every day, often hours sooner than they would have been
detected otherwise,” Nottidge told The Tennessean.
HCA’s SPOT system uses machine learning to ingest “millions of data points on which patients do and do not develop sepsis,” according to an HCA blog post. “Those computers monitor clinical data every second of a patient’s hospitalization. When a pattern of data consistent with sepsis risk occurs, it will signal with an alert to trained technicians who call a ‘code sepsis.’”
More Accurate than Clinicians
The federal Centers for Disease Control and Prevention (CDC) estimates that more than 250,000 Americans die from sepsis each year. The Sepsis Alliance describes the life-threatening complication as the “leading cause of death in US hospitals.”
Early detection and treatment are key to reducing sepsis mortalities. However, a study in the journal Clinical Medicine reported that, despite recent advances in identifying at-risk patients, “there is still no molecular signature able to diagnose sepsis.”
And according to a study published in Critical Care Medicine, the survival rate is about 80% when treatment is administered in the first hour, but each hour of delay in treatment decreases the average survival rate by 7.6%.
In an interview with Becker’s Hospital Review, HCA’s Chief Medical Officer and President of Clinical Services, Jonathan Perlin, MD, PhD, touted SPOT’s reliability, having “very few false positives. In fact, it is more than 50% more accurate at excluding patients who don’t have sepsis than even the best clinician.”
Perlin also told The Tennessean that SPOT can detect
sepsis “about eight to 10 hours before clinicians ever could.”
“It’s no coincidence that we call the technology ‘SPOT’—a common name for a child’s dog—because it really does act as our sepsis sniffer,” said Jonathan Perlin, MD, PhD (above), in the HCA blog post. “The whole point is for it to sniff smoke and put the ‘fire’ out before it becomes catastrophic. With SPOT, we’re identifying at least one-third more cases of sepsis that would not previously have come to caregivers’ attention until it was too late.” [Photo copyright: Nashville Business Journal.)
Other Healthcare Providers Using AI-Enabled Early-Warning
Tools
In November 2018, the emergency department at Duke University Hospital in Durham, N.C., began a pilot program to test an AI-enabled system dubbed Sepsis Watch, reported Health Data Management. The software, developed by the Duke Institute for Health Innovation, “was trained via deep learning to identify cases based on dozens of variables, including vital signs, medical laboratory test results, and medical histories,” reported IEEE Spectrum. “In operation, it pulls information from patients’ medical records every five minutes to evaluate their conditions, offering intensive real-time analysis that human doctors can’t provide.”
Earlier this year, Sentara Norfolk General Hospital in Norfolk, Va., installed an AI-enabled sepsis-alert system developed by Jvion, a maker of predictive analytics software. “The new AI tool grabs about 4,500 pieces of data about a patient that live in the electronic record—body temperature, heart rate, blood tests, past medical history, gender, where they live and so on—and runs it all through an algorithm that assesses risk for developing sepsis,” reported The Virginian Pilot.
Geisinger Health System, which operates 13 hospitals in Pennsylvania and New Jersey, is working on its own system to identify sepsis risk. It announced in a September news release that it had teamed with IBM to develop a predictive model using a decade’s worth of data from thousands of Geisinger patients.
“The model helped researchers identify clinical biomarkers associated with higher rates of mortality from sepsis by predicting death or survival of patients in the test data,” Geisinger stated in the news release. “The project revealed descriptive and clinical features such as age, prior cancer diagnosis, decreased blood pressure, number of hospital transfers, and time spent on vasopressor medicines, and even the type of pathogen, all key factors linked to sepsis deaths.”
So, can artificial intelligence and predictive analytics
added to medical laboratory test results help prevent sepsis-related deaths in
all hospitals? Perhaps so. Systems like SPOT, Sepsis Watch, and others
certainly are logging impressive results.
It may not be long before similar technologies are aiding
pathologists, microbiologists, and clinical laboratories achieve improved
diagnostic and test accuracy as well.
The self-cleaning material has been proven to repel even the deadliest forms of antibiotic resistant (ABR) superbugs and viruses. This ultimate non-stick coating is a chemically treated form of transparent plastic wrap which can be adhered to surfaces prone to gathering germs, such as door handles, railings, and intravenous therapy (IV) stands.
“We developed the wrap to address the major threat that is posed by multi-drug resistant bacteria,” Leyla Soleymani, PhD, Associate Professor at McMaster University and one of the leaders of the study, told CNN. “Given the limited treatment options for these bugs, it is key to reduce their spread from one person to another.”
According to research published in the peer-reviewed Southern Medical Journal, “KPC-producing bacteria are a group of emerging highly drug-resistant Gram-negative bacilli causing infections associated with significant morbidity and mortality.”
Were those surfaces covered in this new bacterial-resistant
coating, life-threatening infections in hospital ICUs could be prevented.
Taking Inspiration from Nature
In designing their new anti-microbial wrap, McMaster researchers took their inspiration from natural lotus leaves, which are effectively water-resistant and self-cleaning thanks to microscopic wrinkles that repel external molecules. Substances that come in contact with surfaces covered in the new non-stick coating—such as a water, blood, or germs—simply bounce off. They do not adhere to the material.
The “shrink-wrap” is flexible, durable, and inexpensive to
manufacture. And, the researchers hope to locate a commercial partner to
develop useful applications for their discovery.
“We’re structurally tuning that plastic,” Soleymani told SciTechDaily. “This material gives us something that can be applied to all kinds of things.”
In the video above, Leyla Soleymani, PhD, Associate Professor at McMaster University, explains how “The new plastic surface—a treated form of conventional transparent wrap—can be shrink-wrapped onto door handles, railings, IV stands, and other surfaces that can be magnets for bacteria such as MRSA and C. difficile. This may be technology that has great value to clinical laboratories and microbiology laboratories. Click here to watch the video. (Image and video copyright: McMaster University/YouTube.)
Industries Outside of Healthcare Also Would Benefit
According to the US Centers for Disease Control and Prevention (CDC), at least 2.8 million people get an antibiotic-resistant infection in the US each year. More than 35,000 people die from these infections, making it one of the biggest health challenges of our time and a threat that needs to be eradicated. This innovative plastic coating could help alleviate these types of infections.
And it’s not just for healthcare. The researchers said the coating could be beneficial to the food industry as well. The plastic surface could help curtail the accidental transfer of bacteria, such as E. coli, Salmonella, and Listeria in food preparation and packaging, according to the published study.
“We can see this technology being used in all kinds of institutional and domestic settings,” Tohid Didar, PhD, Assistant Professor at McMaster University and co-author of the study, told SciTechDaily. “As the world confronts the crisis of anti-microbial resistance, we hope it will become an important part of the anti-bacterial toolbox.”
Clinical laboratories also are tasked with preventing the
transference of dangerous bacteria to patients and lab personnel. Constant
diligence in application of cleaning protocols is key. If this new anti-bacterial
shrink wrap becomes widely available, medical laboratory managers and
microbiologists will have a new tool to fight bacterial contamination.
