This is good news for clinical laboratories that already perform medical testing for telehealth providers and an opportunity for medical labs that do not, it is an opportunity to do so
Telemedicine visits have become commonplace since the arrival of COVID-19. Before the pandemic, telehealth was primarily used to give remote patients access to quality healthcare providers. But three years later both patients and physicians are becoming increasingly comfortable with virtual office visits, especially among Millennial and Gen Z patients and doctors.
Now, a recent study by the Perelman School of Medicine at the University of Pennsylvania (Penn Medicine) suggests that there could be a significant financial advantage for hospitals that conduct telemedicine. This would be a boon to clinical laboratories that perform medical testing for telemedicine providers.
According to Digital Health News, in July 2017 Penn Medicine launched a 24/7/365 copayment-free telemedicine program for its employees called Penn Medicine OnDemand. To engage with a telemedicine provider, patients must have a smartphone or tablet with a front-facing camera and updated operating system.
Telemedicine Visits Cost Less than In-Office Doctor Appointments
An analysis of the OnDemand program’s data collected from its inception through the end of 2019 found that the telemedicine appointment per-visit cost averaged around $380, whereas the cost of an in-person visit at an emergency department, primary care office, or urgent care clinic averaged around $493.
Typically, Penn Medicine’s employees used the telemedicine program for common, low risk health complaints. Healthcare conditions that many patients might otherwise not seek treatment for if an in-office visit was inconvenient.
“The data we analyzed pre-date the pandemic. It was a time when people were just putting a toe in the water and wondering, ‘Let me see if telemedicine could treat my needs,’” Krisda Chaiyachati MD, an internal medicine physician and Adjunct Assistant Professor at Penn Medicine, told Digital Health News. Chaiyachati lead the research team that conducted the telemedicine study.
“These days, people seem willing to jump in for an appropriate set of conditions,” he added. “The good news is that we made care easier while saving money, and we think the savings could be higher in the future.”
Chaiyachati and his colleagues found that telemedicine can save employers healthcare costs without sacrificing quality of care.
“The conditions most often handled by OnDemand are low acuity—non-urgent or semi-urgent issues like respiratory infections, sinus infections, and allergies—but incredibly common, so any kind of cost reduction can make a huge difference for controlling employee benefit costs,” Krisda Chaiyachati MD (above), a Penn Medicine physician and the study’s lead researcher, told Digital Health News.

Telemedicine on the Rise
The idea is not new. In late 2018, Planned Parenthood launched the Planned Parenthood Direct mobile app in New York State. The app provides New York patients with access to birth control, emergency contraception, and UTI treatment with no in-person visit required.
The program has since expanded across the country. Users of the app can connect with a physician to go over symptoms/needs, and the be sent a prescription within a business day to the pharmacy of their choice.
The concept is similar to Penn Medicine OnDemand, which gives patients 24/7 year around access to treatment for common and low-acuity medical issues in a convenient, virtual process.
Telemedicine was on the rise in other parts of the healthcare industry before the pandemic. According to “The State of Telehealth Before and After the COVID-19 Pandemic” published by Julia Shaver, MD, Kaiser Permanente, in the journal Primary Care: Clinics in Office Practice, 76% of US hospital systems had utilized some form of telemedicine by 2018. This rate grew exponentially while the healthcare system had to navigate a world with COVID-19 on the rise.
And, apparently, quality of care does not suffer when moved from in-person to virtual settings. Two studies conducted by The University of Rochester Medical Center (URMC) found telemedicine to be effective and that “common concerns about telemedicine don’t hold up to scrutiny,” according a news release.
In her New England Journal of Medicine (NEJM) paper on the studies, Kathleen Fear, PhD, URMC’s Director of Data Analytics, Health Lab, and her co-authors, wrote: “Three beliefs—that telemedicine will reduce access for the most vulnerable patients; that reimbursement parity will encourage overuse of telemedicine; and that telemedicine is an ineffective way to care for patients—have for years formed the backbone of opposition to the widespread adoption of telemedicine.”
However, URMC’s study found the opposite to be true. The NEJM authors wrote, “there is no support for these three common notions about telemedicine. At URMC, the most vulnerable patients had the highest uptake of telemedicine; not only did they complete a disproportionate share of telemedicine visits, but they also did so with lower no-show and cancellation rates. It is clear that … telemedicine makes medical care more accessible to patients who previously have experienced substantial barriers to care.
“Importantly, this access does not come at the expense of effectiveness. Providers do not order excessive amounts of additional testing to make up for the limitations of virtual visits. Patients do not end up in the ER or the hospital because their needs are not met during a telemedicine visit, and they also do not end up requiring additional in-person follow-up visits to supplement their telemedicine visit,” the NEJM authors concluded.
“Not only did our most vulnerable patients not get left behind—they were among those engaging the most with, and benefiting the most from, telemedicine services. We did not see worse outcomes or increased costs, or patients needing an increased amount of in-person follow up. Nor did we find evidence of overuse. This is good care, and it is equitable care for vulnerable populations,” Fear said in the news release.
“For patients, the message is clear and reassuring: Telemedicine is an effective and efficient way of receiving many kinds of healthcare,” she added.
Opportunities for Clinical Laboratories
Dark Daily has covered the fast growing world of telemedicine in many ebriefs over the years.
As telemedicine broadens its reach across the healthcare world, clinical laboratories and pathology groups would be wise to seek collaboration with health plans and providers of telemedicine to figure out where sample collection and testing fits into this new virtual healthcare space.
Three innovative technologies utilizing CRISPR-Cas13, Cas12a, and Cas9 demonstrate how CRISPR might be used for more than gene editing, while highlighting potential to develop new diagnostics for both the medical laboratory and point-of-care (POC) testing markets
CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) is in the news again! The remarkable genetic-editing technology is at the core of several important developments in clinical laboratory and anatomic pathology diagnostics, which Dark Daily has covered in detail for years.
Now, scientists at three universities are investigating ways to expand CRISPR’s use. They are using CRISPR to develop new diagnostic tests, or to enhance the sensitivity of existing DNA tests.
One such advancement improves the sensitivity of SHERLOCK (Specific High Sensitivity Reporter unLOCKing), a CRISPR-based diagnostic tool developed by a team at MIT. The new development harnesses the DNA slicing traits of CRISPR to adapt it as a multifunctional tool capable of acting as a biosensor. This has resulted in a paper-strip test, much like a pregnancy test, that can that can “display test results for a single genetic signature,” according to MIT News.
Such a medical laboratory test would be highly useful during pandemics and in rural environments that lack critical resources, such as electricity and clean water.
One Hundred Times More Sensitive Medical Laboratory Tests!
MIT News highlighted the high specificity and ease-of-use of their system in detecting Zika and Dengue viruses simultaneously. However, researchers stated that the system can target any genetic sequence. “With the original SHERLOCK, we were detecting a single molecule in a microliter, but now we can achieve 100-fold greater sensitivity … That’s especially important for applications like detecting cell-free tumor DNA in blood samples, where the concentration of your target might be extremely low,” noted Abudayyeh.
“The [CRISPR] technology demonstrates potential for many healthcare applications, including diagnosing infections in patients and detecting mutations that confer drug resistance or cause cancer,” stated senior authorFeng Zhang, PhD. Zhang, shown above in the MIT lab named after him, is a Core Institute Member of the Broad Institute, Associate Professor in the departments of Brain and Cognitive Sciences and Biological Engineering at MIT, and a pioneer in the development of CRISPR gene-editing tools.

Creating a Cellular “Black Box” using CRISPR
Another unique use of CRISPR technology involved researchers David Liu, PhD, and Weixin Tang, PhD, of Harvard University and Howard Hughes Medical Institute (HHMI). Working in the Feng Zhang laboratory at the Broad Institute, they developed a sort of “data recorder” that records events as CRISPR-Cas9 is used to remove portions of a cell’s DNA.
They published the results of their development of CRISPR-mediated analog multi-event recording apparatus (CAMERA) systems, in Science. The story was also covered by STAT.
“The order of stimuli can be recorded through an overlapping guide RNA design and memories can be erased and re-recorded over multiple cycles,” the researchers noted. “CAMERA systems serve as ‘cell data recorders’ that write a history of endogenous or exogenous signaling events into permanent DNA sequence modifications in living cells.”
This creates a system much like the “black box” recorders in aircraft. However, using Cas9, data is recorded at the cellular level. “There are a lot of questions in cell biology where you’d like to know a cell’s history,” Liu told STAT.
While researchers acknowledge that any medical applications are in the far future, the technology holds the potential to capture and replay activity on the cellular level—a potentially powerful tool for oncologists, pathologists, and other medical specialists.
Using CRISPR to Detect Viruses and Infectious Diseases
Another recently developed technology—DNA Endonuclease Targeted CRISPR Trans Reporter (DETECTR)—shows even greater promise for utility to anatomic pathology groups and clinical laboratories.
Also recently debuted in Science, the DETECTR system is a product of Jennifer Doudna, PhD, and a team of researchers at the University of California Berkeley and HHMI. It uses CRISPR-Cas12a’s indiscriminate single-stranded DNA cleaving as a biosensor to detect different human papillomaviruses (HPVs). Once detected, it signals to indicate the presence of HPV in human cells.
Despite the current focus on HPVs, the researchers told Gizmodo they believe the same methods could identify other viral or bacterial infections, detect cancer biomarkers, and uncover chromosomal abnormalities.
Future Impact on Clinical Laboratories of CRISPR-based Diagnostics
Each of these new methods highlights the abilities of CRISPR both as a data generation tool and a biosensor. While still in the research phases, they offer yet another possibility of improving efficiency, targeting specific diseases and pathogens, and creating new assays and diagnostics to expand medical laboratory testing menus and power the precision medicine treatments of the future.
As CRISPR-based diagnostics mature, medical laboratory directors might find that new capabilities and assays featuring these technologies offer new avenues for remaining competitive and maintaining margins.
However, as SHERLOCK demonstrates, it also highlights the push for tests that produce results with high-specificity, but which do not require specialized medical laboratory training and expensive hardware to read. Similar approaches could power the next generation of POC tests, which certainly would affect the volume, and therefore the revenue, of independent clinical laboratories and hospital/health system core laboratories.
Researchers, including pathologists, can use Apple’s ResearchKit app to help collect and share genetic information about cancers and other diseases while building a huge genome database
By providing tools to allow users to be more productive in working with healthcare big data, several Silicon Valley giants hope to increase their presence in medical services. The latest company to enter the field is Apple Computers (NASDAQ:AAPL). In March it announced the availability of ResearchKit, an open-source software framework that turns the iPhone into a research tool.
Pathologists and clinical laboratory scientists have a stake in the healthcare big data trend, since more than 70% of the typical patient’s permanent medical record consists of medical laboratory test data. Thus, the products introduced by Apple, Google, and other Silicon Valley firms that are designed to help physicians and other professionals work with healthcare big data have the potential to transform the way value is harvested from these data sets.
Apple’s strategy is to support researchers. Its ResearchKit is designed to be an open-source software framework that turns the iPhone into a research tool. It enables development of apps that help medical researchers recruit study subjects and collect health information through iPhone’s sensors and surveys. Because it is an open-source platform, researchers also can create apps for Android and Windows devices. (more…)
