In a separate study, HHS finds a 40% increase in sepsis cases, as more patients succumb to infections without effective antibiotics and antimicrobial drugs
Given the drastic steps being taken to slow the spread of the Coronavirus in America, it’s easy to forget that significant numbers of patients die each year due to antibiotic-resistant bacteria (ARB), other forms of antimicrobial resistance (AMR), and in thousands of cases the sepsis that follows the infections.
The CDC’s website states that “more than 2.8 million antibiotic-resistant infections occur in the US each year, and more than 35,000 people die as a result.” And a CDC news release states, “on average, someone in the United States gets an antibiotic-resistant infection every 11 seconds and every 15 minutes someone dies.”
Those are huge numbers.
Clinical laboratory leaders and microbiologists have learned to be vigilant as it relates to dangerously infectious antimicrobial-resistant agents that can result in severe patient harm and death. Therefore, new threats identified in the CDC’s Antibiotic Resistance Threats in the United States report will be of interest.
Drug-resistant Microbes That Pose Severe Risk
The CDC has added the fungus Candida auris (C. auris) and carbapenem-resistant Acinetobacter (a bacteria that can survive for a long time on surfaces) to its list of “urgent threats” to public health, CDC said in the news release. These drug-resistant microbes are among 18 bacteria and fungi posing a greater threat to patients’ health than CDC previously estimated, Live Science reported.
In 2013, the CDC estimated that about two million people each year acquired an antibiotic-resistant (AR) infection that killed as many as 23,000. However, in 2019, the CDC reported that those numbers were low and that the number of deaths due to AR infections in 2013 was about twice that amount. During a news conference following the CDC announcement, Michael Craig (above), a Senior Adviser for the CDC’s Antibiotic Resistance Coordination and Strategy Unit said, “We knew and said [in 2013] that our estimate was conservative … and we were right,” Live Science reported. In 2019, CDC reported 2.8 million antibiotic-resistant infections annually with more than 35,000 related deaths in the US alone. (Photo copyright: Centers for Disease Control and Prevention.)
The CDC considers five threats to be urgent. Including the
latest additions, they are:
Dark Daily has regularly covered the healthcare industry’s ongoing struggle with deadly fungus and bacteria that are responsible for hospital-acquired infections (HAI) and sepsis. This latest CDC report suggests healthcare providers continue to struggle with antimicrobial-resistant agents.
Acinetobacter Threat Increases and C. auris
a New Threat since 2013
Carbapenem-resistant Acinetobacter, a bacterium that
causes pneumonia and bloodstream and urinary tract infections, escalated from
serious to urgent in 2013. About 8,500 infections and 700 deaths were noted by the
CDC in 2017.
C. auris, however, was not addressed in the 2013
report at all. “It’s a pathogen that we didn’t even know about when we wrote
our last report in 2013, and since then it’s circumvented the globe,” said Michael
Craig, Senior Adviser for the CDC’s Antibiotic Resistance Coordination and
Strategy Unit, during a news conference following the CDC announcement, Live
Science reported.
Today, C. auris is better understood. The fungus
resists emerging drugs, can result in severe infections, and can be transmitted
between patients, CDC noted.
By year-end, CDC tracking showed 988 cases in the US.
More Patients Getting Sepsis as Antibiotics Fail: HHS
Study
In a separate study published in Critical Care Medicine, a journal of the Society of Critical Care Medicine (SCCM), the US Department of Health and Human Services (HHS) found that antibiotic-resistant bacteria and fungi are resulting in more people acquiring sepsis, a life-threatening condition, according to an HHS news release.
Sepsis increased by 40% among hospitalized Medicare patients
from 2012 through 2018, HHS reported.
“These (untreatable infections) are happening here and now in the United States in large numbers. This is isn’t some developing world thing. This isn’t a threat for 2050. It’s a threat for here and now,” Cornelius “Neil” Clancy, MD, Associate Chief of Veterans Affairs Pittsburg Health System (VAPHS) and Opportunistic Pathogens, told STAT.
It is troubling to see data about so many patient deaths
related to antibiotic-resistant infections and sepsis cases when the world is
transfixed by the Coronavirus. Nevertheless, it’s important that medical laboratory
leaders and microbiologists keep track of how the US healthcare system is or is
not responding to these new infectious agents. And, to contact infection
control and environmental services colleagues to enhance surveillance, ensure
safe healthcare environments and equipment, and adopt appropriate strategies to
prevent antibiotic-resistant infections.
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 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 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.
Genomic analysis of pipes and sewers leading from the National Institutes of Health Clinical Care Center in Bethesda, Md., reveals the presence of carbapenem-resistant organisms; raises concern about the presence of multi-drug-resistant bacteria previously undetected in hospital settings
If hospitals and medical laboratories are battlegrounds, then microbiologists and clinical laboratory professionals are frontline soldiers in the ongoing fight against hospital-acquired infections (HAIs) and antibiotic resistance. These warriors, armed with advanced testing and diagnostic skills, bring expertise to antimicrobial stewardship programs that help block the spread of infectious disease. In this war, however, microbiologists and medical laboratory scientists (AKA, medical technologists) also often discover and identify new and potential strains of antibiotic resistance.
Potential Source of Superbugs and Hospital-Acquired Infections
According to the mBio study, “Carbapenemase-producing organisms (CPOs) are a global concern because of the morbidity and mortality associated with these resistant Gram-negative bacteria. Horizontal plasmid transfer spreads the resistance mechanism to new bacteria, and understanding the plasmid ecology of the hospital environment can assist in the design of control strategies to prevent nosocomial infections.”
Karen Frank, MD, PhD (above), is Chief of the Microbiology Service Department at the National Institutes of Health and past-president of the Academy of Clinical Laboratory Physicians and Scientists. She suggests hospitals begin tracking the spread of the bacteria. “In the big picture, the concern is the spread of these resistant organisms worldwide, and some regions of the world are not tracking the spread of the hospital isolates.” (Photo copyright: National Institutes of Health.)
Frank’s team used Illumina’s MiSeq next-generation sequencer and single-molecule real-time (SMRT) sequencing paired with genome libraries, genomics viewers, and software to analyze the genomic DNA of more than 700 samples from the plumbing and sewers. They discovered a “potential environmental reservoir of mobile elements that may contribute to the spread of resistance genes, and increase the risk of antibiotic resistant ‘superbugs’ and difficult to treat hospital-acquired infections (HAIs).”
Genomic Sequencing Identifies Silent Threat Lurking in Sewers
Frank’s study was motivated by a 2011 outbreak of antibiotic-resistant Klebsiella pneumoniae bacteria that spread through the NIHCC via plumbing in ICU, ultimately resulting in the deaths of 11 patients. Although the hospital, like many others, had dedicated teams working to reduce environmental spread of infectious materials, overlooked sinks and pipes were eventually determined to be a disease vector.
In an NBC News report on Frank’s study, Amy Mathers, MD, Director of The Sink Lab at the University of Virginia, noted that sinks are often a locus of infection. In a study published in Applied and Environmental Microbiology, another journal of the ASM, Mathers noted that bacteria in drains form a difficult to clean biofilm that spreads to neighboring sinks through pipes. Mathers told NBC News that despite cleaning, “bacteria stayed adherent to the wall of the pipe” and even “splashed out” into the rooms with sink use.
During the 2011-2012 outbreak, David Henderson, MD, Deputy Director for Clinical Care at the NIHCC, told the LA Times of the increased need for surveillance, and predicted that clinical laboratory methods like genome sequencing “will become a critical tool for epidemiology in the future.”
Frank’s research fulfilled Henderson’s prediction and proved the importance of genomic sequencing and analysis in tracking new potential sources of infection. Frank’s team used the latest tools in genomic sequencing to identify and profile microbes found in locations ranging from internal plumbing and floor drains to sink traps and even external manhole covers outside the hospital proper. It is through that analysis that they identified the vast collection of CPOs thriving in hospital wastewater.
In an article, GenomeWeb quoted Frank’s study, noting that “Over two dozen carbapenemase gene-containing plasmids were identified in the samples considered” and CPOs turned up in nearly all 700 surveillance samples, including “all seven of the wastewater samples taken from the hospital’s intensive care unit pipes.” Although the hospital environment, including “high-touch surfaces,” remained free of similar CPOs, Frank’s team noted potential associations between patient and environmental isolates. GenomeWeb noted Frank’s findings that CPO levels were in “contrast to the low positivity rate in both the patient population and the patient-accessible environment” at NIHCC, but still held the potential for transmission to vulnerable patients.
Since carbapenems are a “last resort” antibiotic for bacteria resistant to other antibiotics, the NIHCC “reservoir” of CPOs is a frightening discovery for physicians, clinical laboratory professionals, and the patients they serve.
The high CPO environment in NIHCC wastewater has the capability to spread resistance to bacteria even without the formal introduction of antibiotics. In an interview with Healthcare Finance News, Frank indicated that lateral gene transfer via plasmids was not only possible, but likely.
“The bacteria fight with each other and plasmids can carry genes that help them survive. As part of a complex bacterial community, they can transfer the plasmids carrying resistance genes to each other,” she noted. “That lateral gene transfer means bacteria can gain resistance, even without exposure to the antibiotics.”
The discovery of this new potential “reservoir” of CPOs may mean new focused genomic work for microbiologists and clinical laboratories. The knowledge gained by the discovery of CPOs in hospital waste water and sinks offers a new target for study and research that, as Frank concludes, will “benefit healthcare facilities worldwide” and “broaden our understanding of antimicrobial resistance genes in multi-drug resistant (MDR) bacteria in the environment and hospital settings.”
High-powered hand dryers, like those used in public restrooms, are the latest targets in pursuit of cleanliness in public and medical environments
Microbiologists and clinical laboratory scientists will be fascinated by the findings of a research study into a method of hand drying that the study scientists described as like “virus hand grenades.” If these findings are confirmed by other studies, it may lead to changes in how hand washing stations in hospitals and medical laboratories are equipped, among other things.
Clinical laboratory personnel and pathology group members come into contact with, and fight against, biological contamination on a daily basis. Proper hand-washing/drying and waste disposal techniques, therefore, are critical functions for any well-run medical laboratory. That is why it is significant to learn that today’s most common hand-drying apparatus—the Jet Air Dryer—could be responsible for spreading infections germs through its everyday usage.
After studying hand-drying techniques, researchers at The University of Westminster in London determined that high-powered jet air dryers can act like “virus hand grenades.” The study, published in the Journal of Applied Microbiology earlier this year, compared the virus-spreading capabilities of three different types of hand-drying techniques:
1. Warm air dryers;
2. Jet air dryers; and
3. Paper towels.
To perform the research, participants placed MS2, an “icosahedral, positive-sense single-stranded RNA virus that infects the bacterium Escherichia coli and other members of the Enterobacteriaceae,” on their gloved hands. They then dried their hands using the various drying methods. Samples were collected around the three devices from different heights and distances on petri dishes and from the air to rate the capacity of these hand-drying devices to scatter contaminants into the surrounding environment.
Blowing Viruses Throughout the Room
The scientists discovered the jet air hand dryers could disperse viruses up to nine feet from the device. By contrast, the more commonly used and less powerful warm air dryer spewed the MS2 three feet from the machine. Paper towels were only able to disperse the virus a mere 10 inches.
Based on research originally published in the Journal of Hospital Infection, the graphic above demonstrates how the various hand-drying methods alter the spread of viruses, described by Westminster researchers. These findings will be of interest to microbiologists, pathologists and medical laboratory scientists involved in infection-control programs at their hospitals and labs. (Graphic copyright: Food Safety Consortium, Ltd.)
The type of hand dryer used for the study was the Dyson Airblade. The researchers learned that the high-powered Airblade spread 60 times more germs into the air than the lower-powered warm air dryers and scattered 1,300 more viruses than the paper towels.
Dyson criticized the study, noting that the scientists had an unusually high amount of the virus on their hands. The company also stated that while paper towels may not dispense viruses into the air, they can be polluted with germs and spread them to other people. In addition, Dyson claims on its website that “up to 88% of unused paper towels tested in the US contain bacteria, which can transfer to your hands.”
Dyson has also alleged that such studies are funded by the paper towel industry to discredit the effectiveness of their products.
Thorough Hand Washing a Critical Step
In addition to having a large amount of the virus on their hands, it is worth noting that the researchers did not attempt to wash the MS2 from their hands before using the assorted drying techniques. People typically have washed their hands with soap and water before operating any type of hand dryer or wiping their hands with paper towels. Although it is debatable which hand-drying method is the most hygienic, obviously the best practice is to thoroughly wash hands and dry them with whatever hand-dryer is available.
Hand hygiene is widely known to be a crucial element in minimizing the transmission of pathogenic micro-organisms that can cause infections. According to the Westminster study, “it has been estimated that cross-infection contributes to 40% of cases of healthcare-associated infections and hand hygiene compliance represents an essential step in minimizing such infections.”
Choosing Best Hand Dryer for Medical Environments, Clinical Laboratories
The researchers noted that, “the choice of hand-drying device should be considered carefully in areas where infection prevention concerns are paramount, such as healthcare settings and the food industry.”
In the past, microbiologists have performed studies where they have swabbed the hands of medical staff, equipment, and surfaces to demonstrate the presence of infectious agents. One study even examined doctors’ neckties and found the existence of bacteria that can cause infections, such as:
In 2013, Weill Cornell Medical College launched PathoMap to study genetic material in the New York City Subway System. Their objective was to establish a molecular view of the city to positively impact public health.
Weill researchers discovered genetic material from more than 15,000 species among 1,400 samples collected from 468 subway stations. The material was mostly harmless or unidentified.
PathoMap recently implemented MetaSUB, which stands for “Metagenomics and Metadesign of Subways and Urban Biomes,” to perform similar studies of mass-transit systems in 39 cities on six continents. The goal is to help city planners, public health officials, and designers create healthier environments.
Whether “virus hand grenades” are fact or myth, targeted research such as the studies above highlight the critical need for clinical laboratories and other medical practices to understand how the devices used in hand washing and hand drying contribute to improved hygiene and lower infection rates that help protect patients as well as physicians, nurses, medical laboratory scientists, and other healthcare workers.
