“The SDPR will consolidate geographically fragmented EMR, PAS, and LIMS systems to create a detailed lifelong patient record and deliver cost savings,” NSW Health said in a news release.
NSW Health is the largest public health system in Australia with more than 220 public hospitals, 16 Local Health Districts, and three Specialty Networks. NSW Health Pathology operates more than 60 pathology laboratories (clinical laboratories in the US) and has 150 patient service centers.
“While this initiative will provide untold benefits to all the patients of NSW, we are excited about its potential for improving the health outcomes of our regional patients,” said Andrew Montague (above), former Chief Executive, Central Coast Local Health District in a press release. “By enabling greater collaboration across all local health districts and specialty health networks, the Single Digital Patient Record will provide clinicians with even better tools to keep the patient at the center of everything we do.” This project is more market evidence of the trend to bring clinical laboratory test results from multiple lab sites into a single data repository.

Cloud-based Realtime Access to Patient Records
Australia has a population of about 26 million and New South Wales, a state on the east coast, is home to more than eight million people. Though the scale of healthcare in Australia is much smaller than in the US, this is still a major project to pull patient data together from all the NSW hospitals, physicians’ offices, and other healthcare providers such as clinical laboratories and pathology practices.
With the change, NSW clinicians will benefit from a cloud–based system offering up real-time access to patients’ medical records, NSW Health Pathology Chief Executive Tracey McCosker told ITnews.
“Patients and our busy staff will benefit from clinical insights gained from the capture of important new data. Our work in pathology is vital to the diagnostic process and developing a statewide laboratory information management system will ensure we provide the best possible services,” McCosker told ITnews.
The KLAS Research report, “US Hospital Market Share 2022,” states that Epic, located in Verona, Wisconsin, has the largest US electronic health record (EHR) market share, Healthgrades noted. According to KLAS:
NSW Health’s decision to engage Epic came after a process involving 350 clinicians, scientists, and technical experts, Zoran Bolevich, MD, Chief Executive of eHealth NSW and NSW Health’s Chief Information Officer, told ITnews.
NSW Health’s Goal for Statewide Digital Patient Record
It was in December 2020 when NSW Health announced its plan to create the SDPR.
“Our vision is to be able to provide a single, holistic, statewide view of every patient—and for that information to be readily accessible to anyone involved in the patient’s care,” Bolevich said in the news release.
The SDPR, according to NSW Health, will address the following:
Challenges:
Current systems not connected statewide.
Inaccessible patient data.
Duplicative data collection.
Gaps in decision-making.
Goals:
Improve health outcomes.
Create patient centricity.
Leverage insights.
NSW’s government has already invested more than $106 million in the SDPR, Healthcare IT News reported.
Other Large EHR Rollouts
NSW Health is not the only large organization to take on such an ambitious project of creating a large-scale digital patient record. And not always to a successful conclusion.
The US Department of Veterans Affairs (VA)—also intent on EHR modernization—recently announced it is suspending roll-out of the Oracle Cerner EHR at VA centers until June 2023 to address technical issues affecting appointments, referrals, and test results.
Four VA centers in Washington, Oregon, and Ohio already went live with the system in 2022.
“We are delaying all future deployments of the new EHR while we fully assess performance and address every concern. Veterans and clinicians deserve a seamless, modernized health record system, and we will not rest until they get it,” said Deputy Secretary of Veterans Affairs Donald Remy, JD, in a news release.
For its part, Oracle Cerner wrote federal lawmakers noting the importance of continuing the project, which will move the VA away from its former VistA health information system.
“Modernization requires change and some short-term pain for the long-term benefits of a modern technology infrastructure,” noted Oracle Cerner Executive Vice President Ken Glueck in the letter, Becker’s Health IT reported. “A modernization project of this scale and scope necessarily involves time to untangle the decades of customized processes established in support of VistA, which inevitably involves challenges.”
NSW Health’s goal is to build a single repository of health information—including lab test results from multiple clinical laboratory sites. When finished NSW Health expects that sharing patient data will contribute to producing better healthcare outcomes.
However, the VA’s experience—and several other similar attempts at large-scale electronic patient record installations—suggest the work ahead will not be easy. But for NSW Health, it may be worth the effort.
Study findings could lead to new biomarker targets for clinical laboratories working to identify AMR bacteria
Reducing and managing antimicrobial resistance (AMR) is a major goal of researchers and health systems across the globe. And it is the job of microbiologists and clinical laboratories to identify microbes that are AMR and those which are not to guide physicians as to the most appropriate therapies for patients with bacterial infections.
“AMR is a silent pandemic of much greater risk to society than COVID-19. In addition to 10 million deaths per year by 2050, the WHO estimates AMR will cost the global economy $100 trillion if we can’t find a way to combat antibiotic failure,” Timothy Barnett, PhD (above), Deputy Director and head of the Strep A Pathogenesis and Diagnostics team at Wesfarmers Centre of Vaccines and Infectious Diseases, told News Medical. Additional research may provide new targets for clinical laboratories tasked with identifying antimicrobial resistant bacteria. (Photo copyright: University of Western Australia.)
Rendering an Antibiotic Ineffective
According to the University of Oxford, about 1.2 million people died worldwide in 2019 due to AMR, and antimicrobial-resistant infections played a role in as many as 4.95 million deaths that same year. The World Health Organization (WHO) declared AMR one of the top ten global public health threats facing humanity.
While investigating antibiotic sensitivity of Group A Streptococcus—a potentially deadly bacteria often detected on the skin and in the throat—the Australian researchers uncovered a mechanism that enabled bacteria to absorb nutrients from their human host and evade the antibiotic sulfamethoxazole, a commonly-prescribed treatment for Group A Strep.
“Bacteria need to make their own folates to grow and, in turn, cause disease. Some antibiotics work by blocking this folate production to stop bacteria growing and treat the infection,” Timothy Barnett, PhD, Deputy Director of the Wesfarmers Centre of Vaccines and Infectious Diseases and head of the Strep A Pathogenesis and Diagnostics team, told News Medical.
“When looking at an antibiotic commonly prescribed to treat Group A Strep skin infections, we found a mechanism of resistance where, for the first time ever, the bacteria demonstrated the ability to take folates directly from its human host when blocked from producing their own. This makes the antibiotic ineffective and the infection would likely worsen when the patient should be getting better,” he added.
According to their study, the researchers identified an energy-coupling (ECF) factor transporter S component gene that allows Group A Strep to acquire extracellular reduced folate compounds that likely “expands the substrate specificity of an endogenous ECF transporter to acquire reduced folate compounds directly from the host, thereby bypassing the inhibition of folate biosynthesis by sulfamethoxazole.”
The study indicates that this new form of antibiotic resistance is indistinguishable under traditional testing used in microbiology and clinical laboratories, which in turn makes it difficult for clinicians to prescribe effective antibiotics to fight an infection.
Understanding AMR before It Is Too Late
The research suggests that understanding AMR is more complicated and intricate than previously thought. Barnett and his team believe their discovery is just the “tip of the iceberg” and that it will prove to be a far-reaching issue across other bacterial pathogens in addition to Group A Strep.
“Without antibiotics, we face a world where there will be no way to stop deadly infections, cancer patients won’t be able to have chemotherapy and people won’t have access to have life-saving surgeries,” Barnett told News Medical. “In order to preserve the long-term efficacy of antibiotics, we need to further identify and understand new mechanisms of antibiotic resistance, which will aid in the discovery of new antibiotics and allow us to monitor AMR as it arises.”
More research and clinical studies are needed before this discovery can become technology that clinical laboratories can use to test if microbes are AMR. The scientists at Wesfarmers Centre of Vaccines and Infectious Diseases are now developing testing methods to detect the presence of the antibiotic resistant mechanism and determine the best treatment options.
“It is vital we stay one step ahead of the challenges of AMR and, as researchers, we should continue to explore how resistance develops in pathogens and design rapid accurate diagnostic methods and therapeutics,” Kalindu Rodrigo, a PhD student in the Barnett lab and one of the authors of the study told News Medical. “On the other hand, equal efforts should be taken at all levels of the society including patients, health professionals, and policymakers to help reduce the impacts of AMR.”
These new insights might lead to a new line of clinical laboratory testing, particularly if the results could guide the patient to microbiome-based repellents that would remain effective for months once applied
Researchers are beginning to identify what compounds make individuals more attractive to mosquitos. That is a first step in the development of a biomarker that could be developed into a clinical laboratory test. Question is: would there be enough consumers wanting to do a lab test to determine if they were highly attractive to mosquitos, thus making this a revenue-generating test for labs?
The SA article reported on their study published in the journal Cell titled, “Differential Mosquito Attraction to Humans Is Associated with Skin-Derived Carboxylic Acid Levels.” The researchers, according to SA, found that individual humans have “a unique scent profile made up of different chemical compounds” and that “mosquitoes were most drawn to people whose skin produces high levels of carboxylic acids.” The researchers also found that “attractiveness to mosquitoes remained steady over time, regardless of changes in diet or grooming habits.”
At a minimum, there would be widespread consumer interest to at least understand why some individuals get more mosquito bites than others. What may be of particular interest to microbiologists is the statement by molecular biologist Omar Akbari, PhD, of the University of California, San Diego, who told Scientific American that by “taking human-colonizing skin bacteria … and engineering them in such a way that they can either express a repellent compound or be able to degrade something that’s attractive,” a mosquito repellant could be developed that would last for months once applied.
“This study clearly shows that these acids are important,” neurogeneticist Matthew DeGennaro, PhD (above), told CNN. “… how the mosquitoes perceive these carboxylic acids is interesting because these particular chemicals … are hard to smell at a distance. It could be that these chemicals are being altered by … the skin microbiome … if we understand why mosquitoes find a host, we can design new repellents that will block the mosquitoes from sensing those chemicals, and this could be used to improve our current repellents.” Clinical laboratory testing will be needed to produce biomarkers for developing such improved repellents.

Clinical Laboratory Testing Needed to Identify Levels of Carboxylic Acids
To complete their study, the researchers had 64 participants wear nylon stockings for six hours on their arms to get their unique scent into the fabric. The scent on the stockings was not discernible to the human nose, but it was to the mosquitos.
Two pieces of the nylon were then placed in a closed container with Aedes aegypti mosquitoes. The researchers found that certain samples were more popular with the mosquitos than others. Upon further analysis the researchers found that the most popular samples came from subjects with higher levels of carboxylic acids, and the least popular had the lowest levels. The scientists ran the test with the same participants several times over three years and the results remained largely the same.
Carboxylic acid is an organic compound found in humans in sebum, the oily layer protecting our skin. The level at which humans release carboxylic acid varies from person to person. And there is no discernible way the human nose can determine whether a person has the level of carboxylic acid on the skin that mosquitos find desirable. The answer would need to be determined by a diagnostic test performed in a clinical laboratory.
Although the development of a test to determine someone’s susceptibility to mosquitos may be far away, there could be significant consumer interest in developing such a test.
“The question of why some people are more attractive to mosquitoes than others—that’s the question that everybody asks,” Leslie B. Vosshall, PhD, Chief Scientific Officer, Howard Hughes Medical Institute, who led the research team to find out why some people are more attractive to mosquitos than others, told Scientific American. “My mother, my sister, people in the street, my colleagues—everybody wants to know.” She credits their interest as the inspiration for embarking on the study.
“Understanding what makes someone a ‘mosquito magnet’ will suggest ways to rationally design interventions such as skin microbiota manipulation to make people less attractive to mosquitoes. We propose that the ability to predict which individuals in a community are high attractors would allow for more effective deployment of resources to combat the spread of mosquito-borne pathogens,” the researchers wrote in their Cell paper.
Preventing Spread of Deadly Diseases
Although mosquitos are an annoyance, they also can be dangerous vectors of disease.
“Every bite of these mosquitoes puts people into public health danger. Aedes aegypti mosquitoes are vectors for dengue, yellow fever, and Zika,” Vosshall told CNN. “Those people who are magnets are going to be much more likely to be infected with viruses.”
Further research into these early findings may help develop diagnostic tests to protect against the spread of these diseases and identify individuals who are more attractive to the mosquitos, and therefore, more likely to contract and spread disease.
Being able to identify which individuals are mosquito magnets could help keep individuals safe from dangerous diseases, and development of a better repellent could also make outdoor summer events more bearable for the (unfortunately) popular among the pests. Medical laboratory tests associated with determining an individual’s susceptibility to mosquito bites could give clinical laboratories a new way to add value to consumers and patients.
Fujifilm acquired Inspirata’s Dynamyx digital pathology technology and business while GE Healthcare announced a partnership with Tribun Health in Europe
Clinical pathology laboratories, especially in the US, have been slow to adopt digital imaging systems. But recent industry deals suggest that the market may soon heat up, at least in the eyes of vendors. These collaborators may hope that, by integrating diagnostic data, the accuracy and productivity of anatomic pathologists will improve while also shortening the time to diagnosis.
In the press release, Fujifilm stated that 85% of US healthcare organizations use analog systems for pathology. That compares with 86% in Europe and 90% in Asia, the company stated.
“Acquiring Inspirata’s digital pathology business allows Fujifilm to be an even stronger healthcare partner—bridging a technological gap between pathology, radiology, and oncology to facilitate a more collaborative approach to care delivery across the enterprise,” said Fujifilm CEO and president Teiichi Goto in the press release.
The press release cited data from Signify Research, a healthcare technology marketing data firm that is predicting the global market for digital pathology systems would double from $320 million in 2021 to $640 million by 2025.
Fujifilm previously had a deal with Inspirata to sell the Dynamyx system exclusively in the UK, Italy, Spain, Portugal, Belgium, the Netherlands, and Luxembourg, an August press release noted.
“A $320 million global industry in 2021 projected to reach $640 million by 2025, the rising number of cancer cases and the demonstrated benefits of digital pathology are fueling significant demand and market growth in the hospital and pharmaceutical industries,” said Henry Izawa (above), president and CEO, Fujifilm Healthcare Americas Corporation, in a press release. “These evolving clinical needs fuel Fujifilm’s investment and innovation in the digital revolution, and we look forward to introducing Dynamyx and its host of unique features and benefits to our Synapse customers and prospects as we strive to enable more efficient medical diagnosis and high-quality care.” (Photo copyright: LinkedIn.)
In announcing their new collaboration, GE Healthcare and Tribun Health said the integration of their systems—Edison Datalogue and the Tribun Health suite—would foster collaboration between pathologists and clinicians by providing a consolidated location for imaging records. This capability is especially important in oncology, they said.
“The oncology care pathway is one of the most complex with multiple steps involving a variety of specialists, complex tools, frequent decisions, and large data sets,” said GE Healthcare CEO of Enterprise Digital Solutions Nalinikanth Gollagunta in a GE press release. “With this digital pathology collaboration, we continue our journey towards simplifying the oncology care pathway with improved data management, the digitization of pathology, and streamlined data access.”
Tribun Health, based in Paris, France, offers a digital pathology platform that incorporates a camera system, artificial intelligence (AI)-based analysis, remote collaboration, and storage management, plus integration with third-party automation apps.
GE Healthcare claims that Edison Datalogue has the largest share of the Vendor Neutral Archive (VNA) market. That term refers to image archiving systems that use standard formats and interfaces instead of proprietary formats. They are an alternative to the more widely used Picture Archiving and Communications Systems (PACS) used in medical imaging.
The collaboration between the companies “is probably a strategic move to position GE as an integrator of imaging data and digital pathology data in oncology,” said Robert Michel Editor-in-Chief of Dark Daily and its sister publication The Dark Report.
GE’s History with Dynamyx
This is not GE Healthcare’s first foray into digital pathology. In fact, the company had a major hand in launching the very Dynamyx system that Fujifilm recently acquired.
In “GE Healthcare Sells Omnyx to Inspirata,” The Dark Report interviewed Inspirata CEO Satish Sanan who at that time said the acquisition would allow his company to offer “a fully integrated, end-to-end digital pathology solution” in Canada and Europe. But GE Healthcare chose to end the partnership in 2016, citing regulatory uncertainty and variable global demand. Two years later, GE sold Omnyx to Inspirata.
GE Healthcare’s new collaboration with Tribun Health shows that the company “still recognizes the value of the pathology data in cancer diagnosis and wants to be in a position to manage that digital pathology data,” Michel said.
Fujifilm’s Plans
Fujifilm said it will incorporate Dynamyx into its Synapse Enterprise Imaging suite, which includes VNA, Radiology PACS, and Cardiology PACS. “Future releases of Dynamyx will also create opportunities for Fujifilm to support pharmaceutical and contract research organizations with toxicity testing data management for drug development,” the company stated in the press release.
With its recent moves into digital pathology, Fujifilm will be taking on major competitors including Philips, Danaher, and Roche, MedTech Dive reported.
Clinical laboratories could play a key role in helping users collect their samples correctly, interpret results, and transfer flu test data to their health records
Clinical laboratories may have another opportunity to provide service to their clients and the physicians who treat them. With the success of at-home COVID-19 testing, consumer demand for self-tests is changing and advances in diagnostic technology now make it feasible to make more influenza (flu) tests available for consumers to buy and use at home.
At-home tests for SARS-CoV-2 can be found at pharmacies all across America. But that’s not the case with tests for influenza.
Should self-test flu kits eventually become available and common, clinical laboratories could offer the service of helping consumers understand:
that the test was conducted correctly (specimen collection and analysis),
“Home flu testing would ensure that those who do need and receive antiviral medication for influenza are the ones who need it the most,” and that “we are making our treatment decisions based on data,” infectious disease specialist Christina Yen, MD (above), University of Texas Southwestern Medical Center, told STAT News. At-home flu self-tests could also bring opportunities for clinical laboratories to provide service to healthcare consumers and the physicians who treat them. (Photo copyright: UT Southwestern Medical Center.)
Pros and Cons of Consumers Doing At-home Influenza Testing
According to the federal Centers for Disease Control and Prevention (CDC), COVID-19 and influenza are both upper respiratory illnesses with similar symptoms. So, why don’t we have more at-home flu tests available? Partly because at-home testing is a relatively new phenomenon in modern healthcare.
“It’s really rare, and it’s really new that people are allowed to know about what’s happening inside their body without a physician in the middle,” Harvard epidemiologist Michael Mina, MD, PhD, told STAT News. The article uses the example of at-home pregnancy tests. Despite a prototype for an at-home pregnancy test being created in 1967, it took another decade before an over-the-counter pregnancy test became available to the public.
“The general thinking was, ‘How could a woman possibly know what to do if she found out she was pregnant on her own without a doctor in the room?’ That is a ridiculous concern because women have been doing that for millions of years,” Mina added.
So, why be cautious when it comes to giving patients the option of at-home flu testing?
There are some cons to at-home influenza tests. Average citizens are not clinical laboratory professionals. They might obtain too little sample for an accurate reading or read the results incorrectly. Then, there is the possibility for false-negatives or false-positives.
An at-home test user is not likely to consider the possibility of a false result, however clinicians look at the situation with more nuance. If the patient was still symptomatic or in a high-risk community, the provider could administer a more sensitive medical laboratory test to confirm the previous test results.
“In a Facebook post from mid-November with hundreds of responses, concertgoers compared symptoms and positive test results, many of those from tests taken at home. But those data weren’t added to state public health tallies of COVID’s spread,” STAT News noted.
The larger concern is that samples obtained by at-home self-test users are not submitted for genomic sequencing. This could lead to incomplete data and delay identifying new variants of the coronavirus in communities.
Another barrier to at-home flu testing is that rapid influenza diagnostic testing can be unreliable. In 2009, the rapid influenza tests could only detect the H1N1 influenza virus in a mere 11% of samples, STAT News reported. Because of this, the FDA now requires manufacturers to test their rapid tests against eight different strains that change every year depending upon which strains are prevalent. This could present a problem if individuals use leftover tests from the previous flu season.
Do Pros of At-home Testing Outweigh the Cons?
At-home testing is convenient and makes testing more accessible to patients who may not be able to get to a clinic. Being able to test at home also encourages individuals to take precautions necessary to stop the spread of whichever illness they may have. Given the similarities in symptoms between influenza and COVID-19, people could benefit from having tools at home that correctly identify their illness.
At-home COVID-19 tests are here to stay, and at-home influenza tests may be on the way soon. Clinical laboratories could play an important role in educating the public on the correct handling of these tests.
