Family medicine academic departments in Canada are dealing with a shortage of applicants qualified for their residency programs, mirroring the shortage of pathologists
For the past decade, the number of medical residencies in Alberta Canada that went unfilled have increased each year. Now, just like in many parts of America, the province is experiencing severe medical staffing shortages that includes clinical laboratories and pathology groups.
According to data compiled by the Canadian Resident Matching Service (CaRMS), after the first round of matching for post-graduate training spots as many as 12% of all spots went unfilled, especially in family medicine, the Canadian Broadcasting Corporation (CBC) reported.
Though the trend seems to be worse in Alberta, the resident shortage is affecting the entire Canadian healthcare system. According to the Angus Reid Institute, approximately half of all Canadians cannot find a doctor or get a timely appointment with their current doctor.
That is fueling predictions of an increased physician shortage in coming years, particularly in Alberta.

Internationally Trained versus Home-grown Doctors
Canada’s current doctor shortage appears to be rooted in red tape that determines which MDs qualify for residency matching. According to John Paul Tasker, a senior journalist at the CBC, “there’s no shortage of doctors in Canada. What we have is a shortage of licensed doctors.” In his article, “Canada Is Short of Doctors—and It’s Turning Away Hundreds of Its Own Physicians Each Year,” Tasker notes that there may be as many as 13,000 medical doctors in Canada who are not currently practicing.
What’s standing in the way of Canadian doctors becoming licensed to practice? Some claim the system of residency matching is discriminatory towards Canadian doctors who received their training outside of Canada. Rosemary Pawliuk, President of the Society for Canadians Studying Medicine Abroad, is one of those who believe the system of matching is broken.
“They have cute slogans like, ‘You’re wanted and welcome in Canada,’ but when you look at the barriers, it’s very clear that you should not come home. Their message is essentially, ‘Go away’ and so [doctors] do,” Pawliuk told the CBC.
According the Pawliuk, “the current residency selection system puts internationally trained Canadian doctors at a serious disadvantage,” the CBC reported. “The Canadian public should be entitled to the best qualified Canadian applicant. Whether they’ve graduated from a Canadian school or an international school, whether they’re a Canadian by birth or if they’re an immigrant, they should be competing on individual merit,” she added.
Canada’s Medical School Matching Bias
In Canada’s current matching system, medical schools decide who gets a residency. Critics say the schools are biased towards Canadian-educated doctors and overlook foreign-trained doctors. About 90% of all residencies in Canada are set aside for Canadian-trained doctors and the remaining spots are left for the physicians trained abroad, CBC noted.
It is important to note that these doctors who are trained abroad are either Canadian citizens or permanent residents. Thus, it’s not a question of citizens from other countries competing with Canadian citizens.
So, if a surplus of doctors are being shut out of residency training opportunities, why are there open slots in Alberta? Some believe this indicates individuals are not interested in practicing medicine in Alberta.
But, Nathan Rider, MD, President of the Professional Association of the Resident Physicians of Alberta (PARA), claims he has not heard of residents turning down Alberta. He notes that the factors of where a resident may want to go geographically often depend on factors such as proximity to loved ones, cost of living, and program culture.
But Rinaldi still has concerns, “We may fill them with 42 disinterested people who have no interest in family medicine,” she says.
Anderson admits that “Across the country, over the last five or more years, family medicine has become less popular with medical students graduating from medical schools than it was in the years before.”
Therefore, both Anderson’s and Hemmelgarn’s schools have changed curriculum to put more of an emphasis on family medicine. Perhaps with these changes, and possibly an opening for internationally-trained Canadian doctors to achieve residency positions, Alberta’s—indeed all of Canada’s—residency match days will be better attended.
In the United States, there is little news coverage about serious problems with the health systems in other nations. The experience of residency programs in Canada, as explained above, demonstrates how a different national health system has unique issues that are not identical to issues in the US healthcare system. What is true is that Canada is dealing with a similar shortage of skilled medical technologists (MTs) and clinical laboratory scientists (CLSs), just like here in the United States.
OIG warns that without adequate clinical laboratory testing healthcare organizations could see more deaths and increased spending
Clinical laboratory leaders and pathologists know that lab test volume decreased dramatically during the early months of the COVID-19 pandemic. That was primarily because community lockdowns stopped people from seeing their doctors for the standard range of chronic health conditions, many of which require clinical laboratory tests for diagnosis and chronic disease management.
• 24% reduction in Medicare Part B test volumes in March • 53% in April • 30% in May
The decline of Medicare patients visiting clinical laboratories continued through the balance of 2020. During the first 10 months of the pandemic—March through December 2020—Medicare beneficiaries who pursued lab testing decreased by about 9% compared to the same 10-month period in 2019, according to a news release.
This is a strong indicator that the government’s response to the pandemic had a measurable effect on clinical laboratory testing volume among all age groups, especially among the elderly.
“The cumulative decline in lab test volume across all client labs for [March 9 to April 12] was just over 40%. But in that time, some of our lab customers were hit with a decline of maybe 50% to 60% in test volume,” Kyle Fetter (above), COO, XIFIN, told The Dark Report in 2020. Clinical laboratory testing that originates from a routine patient visit to a doctor—such as blood testing—may have been affected the most, Fetter explained. (Photo copyright: XIFIN.)
Clinical Laboratory Tests Key to Well-being of Patients with Chronic Conditions
The OIG study was limited to Medicare beneficiaries and thus did not provide information about testing fall-off among people who have private health insurance. But in “From Mid-March, Labs Saw Big Drop in Revenue,” Dark Daily’s sister publication The Dark Report reported early in 2020 on a 40% decline in test volumes and the pandemic’s varying effects on clinical labs, anatomic pathology (AP) groups, and AP subspecialties.
The OIG’s Report in Brief on its study recognized that medical laboratory testing is critical to helping healthcare providers manage chronic conditions that affect patients’ well-being and increase their healthcare costs.
“Lab tests are important for beneficiaries with chronic medical conditions, which are associated with hospitalizations, billions of dollars in Medicare costs, and deaths,” the OIG said.
“The information may be useful to stakeholders involved in ensuring that beneficiaries avoid the potential bad outcomes that may result from missing or delaying appropriate care,” the report noted.
Overall, 23.7 million Medicare beneficiaries received medical laboratory tests during the first 10 months of the pandemic, down 2.4 million from 26.1 million in 2019, the OIG reported.
Overall Medicare lab test volume and spending also declined during the reported period:
Part B clinical laboratory tests for Medicare beneficiaries decreased 15% from 419.9 million tests in 2019 to 358.4 million tests in the first 10 months of the pandemic.
Medicare spending for these tests decreased 16% from $6.6 billion in 2019 to $5.5 billion during the first 10 months of the pandemic.
“OIG’s audit of Part B clinical laboratory tests, reimbursed under the Clinical Laboratory Fee Schedule (CLFS) is a useful benchmark for how Medicare beneficiaries received fewer lab tests during the pandemic, especially during the early months,” said Robert Michel, Editor-in-Chief of Dark Daily and The Dark Report.
Medical Laboratory Tests That Were Down Most During COVID-19
The following 10 clinical laboratory tests experienced a 10% or more decline in Medicare beneficiaries seeking them during the pandemic period as compared to pre-pandemic, according to the OIG report:
Comprehensive urine culture test fell 16% to three million Medicare patients.
Uric acid level blood down 13% to 1.9 million Medicare beneficiaries.
Evaluation of antimicrobial drug decreased 17% to 1.74 million Medicare patients.
Folic acid level down 12% to 1.73 million Medicare beneficiaries.
Urinalysis manual test plunged 28% to 1.4 million Medicare patients.
Beyond Medicare, Clinical Laboratory Test Volume Dropped 40%
OIG was not the only organization to analyze medical laboratory testing volume during the pandemic’s early phase.
The Dark Report correlated data tracked by XIFIN, a San Diego-based health information technology (HIT) company providing revenue cycle management services to clinical laboratories and pathology groups. XIFIN’s collected data showed a steep drop in routine test volume as COVID-19 testing ramped up.
“Starting in the third week of March, we saw medical laboratories suffer a sharp drop in routine testing. But at about the same time, many labs began to offset those revenue losses with testing for the novel coronavirus,” Kyle Fetter, XIFIN’s then Executive Vice President and General Manager of Diagnostic Services told The Dark Report in 2020. Fetter is now XIFIN’S Chief Operating Officer.
“Over four weeks beginning March 9, we saw a cumulative drop of over 40% in test volume from all of our lab clients,” he added.
According to XIFIN’s data, lab specialty organizations experienced the following drop in routine testing during the period March 9 to April 16, 2020:
58% at clinical laboratories.
61% at hospital outreach laboratories.
52% at molecular and genetic testing laboratories.
44% at anatomic pathology (AP) groups.
70% to 80% at AP dermatology and other AP subspecialties.
Many medical laboratories are still recovering from the COVID-19 pandemic’s effects on testing volume.
Notably, the OIG’s report acknowledges the importance of adequate clinical laboratory testing and declares that—without these essential lab tests to manage some healthcare conditions—the healthcare industry could see increased morbidity, deaths, and Medicare spending.
Hello primary diagnosis of digital pathology images via artificial intelligence! Goodbye light microscopes!
Digital pathology is poised to take a great leap forward. Within as few as 12 months, image analysis algorithms may gain regulatory clearance in the United States for use in primary diagnosis of whole-slide images (WSIs) for certain types of cancer. Such a development will be a true revolution in surgical pathology and would signal the beginning of the end of the light microscope era.
A harbinger of this new age of digital pathology and automated image analysis is a press release issued last week by Ibex Medical Analytics of Tel Aviv, Israel. The company announced that its Galen artificial intelligence (AI)-powered platform for use in the primary diagnosis of specific cancers will undergo an accelerated review by the Food and Drug Administration (FDA).
FDA’s ‘Breakthrough Device Designation’ for Pathology AI Platform
Ibex stated that “The FDA’s Breakthrough Device Designation is granted to technologies that have the potential to provide more effective treatment or diagnosis of life-threatening diseases, such as cancer. The designation enables close collaboration with, and expedited review by, the FDA, and provides formal acknowledgement of the Galen platform’s utility and potential benefit as well as the robustness of Ibex’s clinical program.”
“All surgical pathologists should recognize that, once the FDA begins to review and clear algorithms capable of using digital pathology images to make an accurate primary diagnosis of cancer, their daily work routines will be forever changed,” stated Robert L. Michel, Editor-in-Chief of Dark Daily and its sister publication The Dark Report. “Essentially, as FDA clearance is for use in clinical care, pathology image analysis algorithms powered by AI will put anatomic pathology on the road to total automation.
“Clinical laboratories have seen the same dynamic, with CBCs (complete blood counts) being a prime example. Through the 1970s, clinical laboratories employed substantial numbers of hematechnologists [hematechs],” he continued. “Hematechs used a light microscope to look at a smear of whole blood that was on a glass slide with a grid. The hematechs would manually count and record the number of red and white blood cells.
“That changed when in vitro diagnostics (IVD) manufacturers used the Coulter Principle and the Coulter Counter to automate counting the red and white blood cells in a sample, along with automatically calculating the differentials,” Michel explained. “Today, only clinical lab old-timers remember hematechs. Yet, the automation of CBCs eventually created more employment for medical technologists (MTs). That’s because the automated instruments needed to be operated by someone trained to understand the science and medicine involved in performing the assay.”
Primary Diagnosis of Cancer with an AI-Powered Algorithm
Surgical pathology is poised to go down a similar path. Use of a light microscope to conduct a manual review of glass slides will be supplanted by use of digital pathology images and the coming next generation of image analysis algorithms. Whether these algorithms are called machine learning, computational pathology, or artificial intelligence, the outcome is the same—eventually these algorithms will make an accurate primary diagnosis from a digital image, with comparable quality to a trained anatomic pathologist.
How much of a threat is automated analysis of digital pathology images? Computer scientist/engineer Ajit Singh, PhD, a partner at Artiman Ventures and an authority on digital pathology, believes that artificial intelligence is at the stage where it can be used for primary diagnosis for two types of common cancer: One is prostate cancer, and the other is dermatology.
On June 17, Ajit Singh, PhD (above), Partner at Artiman Ventures, will lead a special webinar and roundtable discussion for all surgical pathologists and their practice administrators on the coming arrival of artificial intelligence-powered algorithms to aid in the primary diagnosis of certain cancers. Regulatory approval for such solutions may happen by the end of this year. Such a development would accelerate the transition from light microscopes to a fully digital pathology workflow. Singh is shown above addressing the 2018 Executive War College. (Photo copyright: The Dark Report.)
“It is now possible to do a secondary read, and even a first read, in prostate cancer with an AI system alone. In cases where there may be uncertainty, a pathologist can review the images. Now, this is specifically for prostate cancer, and I think this is a tremendous positive development for diagnostic pathways,” he added.
Use of Digital Pathology with AI-Algorithms Changes Diagnostics
Pathologists who are wedded to their light microscopes will want to pay attention to the impending arrival of a fully digital pathology system, where glass slides are converted to whole-slide images and then digitized. From that point, the surgical pathologist becomes the coach and quarterback of an individual patient’s case. The pathologist guides the AI-powered image analysis algorithms. Based on the results, the pathologist then orders supplementary tests appropriate to developing a robust diagnosis and guiding therapeutic decisions for that patient’s cancer.
In his interview with The Dark Report, Singh explained that the first effective AI-powered algorithms in digital pathology will be developed for prostate cancer and skin cancer. Both types of cancer are much less complex than, say, breast cancer. Moreover, the AI developers have decades of prostate cancer and melanoma cases where the biopsies, diagnoses, and downstream patient outcomes create a rich data base from which the algorithms can be trained and tuned.
This webinar is organized as a roundtable discussion so participants can interact with the expert panelists. The Chair and Moderator is Ajit Singh, PhD, Adjunct Professor at the Stanford School of Medicine and Partner at Artiman Ventures.
The panelists (above) represent academic pathology, community hospital pathology, and the commercial sector. They are:
Because the arrival of automated analysis of digital pathology images will transform the daily routine of every surgical pathologist, it would be beneficial for all pathology groups to have one or more of their pathologists register and participate in this critical webinar.
The roundtable discussion will help them understand how quickly AI-powered image analysis is expected be cleared for use by the FDA in such diseases as prostate cancer and melanomas. Both types of cancers generate high volumes of case referrals to the nation’s pathologists, so potential for disruption to long-standing client relationships, and the possible loss of revenue for pathology groups that delay their adoption of digital pathology, can be significant.
On the flip side, community pathology groups that jump on the digital pathology bandwagon early and with the right preparation will be positioned to build stronger client relationships, increase subspecialty case referrals, and generate additional streams of revenue that boost partner compensation within their group.
Also, because so many pathologists are working remotely, Dark Daily has arranged special group rates for pathology practices that would like their surgical pathologists to participate in this important webinar and roundtable discussion on AI-powered primary diagnosis of pathology images.

New advancements in mHealth, though encroaching on testing traditionally performed at clinical laboratories, offer opportunity to expand testing to remote locations
Mobile technology continues to impact clinical laboratories and anatomic pathology groups and is a major driver in precision medicine, as Dark Daily has reported. Most of the mobile-test development which incorporates smartphones as the testing device, however, has been for chemistry and immunoassay types of lab tests. Now, a new developer in Monmouth Junction, NJ, has created a Complete Blood Count (CBC) test that runs on devices attached to smartphones.
Such devices enable doctors to order test panels for patients in remote locations that also may lack resources, such as electricity.
The developer is Essenlix and it calls its new testing device iMOST (instant Mobile Self-Testing). According to the company’s website, which is mostly “Under Construction,” iMOST can provide “accurate blood and other healthcare testing in less than 60 seconds by a smartphone and matchbox-size-attachment, anywhere, anytime, and affordable to everyone.”
Stephen Chou, PhD, Professor of Electrical Engineering at Princeton University founded Essenlix, and told Business Insider that his company is developing something that will basically be “a mobile chemical biological lab in your hand.” (Photo copyright: Essenlix.)
The company description on the Longitude Prize website states that Essenlix “uses multidisciplinary approaches to develop a new innovative platform of simple, fast, ultrasensitive, bio/chemical sensing and imaging for life science, diagnostics, and personal health.
The Longitude Prize competition was established to promote the invention of “an affordable, accurate, fast and easy-to-use test for bacterial infections that will allow health professionals worldwide to administer the right antibiotics at the right time,” the website states.
The Essenlix iMOST mobile-testing device (above) connects to a smartphone (shown right) and enables clinical laboratory technicians to run tests in remote locations from samples taken at time the test. Though still in trials, iMOST, and other similar devices, promise to expand testing to outside of traditional medical laboratory locations and further promote precision medicine.

Essenlix’s iMOST mobile testing system consists of:
a mobile application (app);
the device attachment, which goes over the phone’s camera; and,
a cartridge that holds a sample of blood.
So far, there have been two trials with a total of 92 participants, comparing traditional CBC testing with the Essenlix test. The results were within the FDA’s requirements for allowable error, prompting Chou to tell Business Insider, “Our error is clearly smaller than the FDA’s requirement, so the data is very, very good.”
Chou and his team are working toward FDA approval.
Other Testing Devices That Attached to Smartphones
Aydogan Ozcan, PhD, Professor of Electrical Engineering and Bioengineering at UCLA, and Mats Nilsson, PhD, Professor and Scientific Director of the Science for Life Laboratory at Stockholm University, have developed an attachment that they say can transform “a phone into a biomolecular analysis and diagnostics microscope,” according to The Pathologist. Dark Daily has published many e-briefings on Ozcan’s innovations over the years.
Their goal, the researchers said, was to create technology that can be used in low- and middle-income areas (LMICs), as well as in more advanced locations, such as Sweden. “I’ve been involved in other projects where we’ve looked at point-of-care diagnostic approaches,” he said, “and it seems to be very important that the devices [do not] rely on wired electricity or networks to serve not only LMICs, but also modern, developed environments. It’s often difficult to find an available power socket in Swedish hospitals.”
The molecular diagnostic tests that can be done with smartphone attachments—such as those developed by Ozcan and Nilsson—represent another way of using a smartphone in the healthcare arena, The Pathologist points out. Their invention combines the smartphone’s native camera, an app, optomechanical lasers, and an algorithm contained within the attachment to carry out fluorescence microscopy in the field.
Future of Mobile-Testing
An article appearing in the Financial Times describes some of the ways mobile technology is changing healthcare, including diagnostics that have traditionally been performed in the medical pathology laboratories.
“Doctors scan your body to look for irregularities, but they rely on pathologists in the lab to accurately diagnose any infection,” the article notes. “There, body fluids such as blood, urine, or spit are tested for lurking microbes or unexpected metabolites or chemicals wreaking havoc in your body. Now companies are miniaturizing these tests to create mobile pathology labs.”
Apple introduced the first iPhone in 2007. It’s doubtful anyone imagined the innovations in diagnostics and pathology that would soon follow. Thus, trying to predict what may be coming in coming decades—or even next year—would be futile. However, scientists and researchers themselves are indicating the direction development is headed.
Should Essenlix and other mobile-lab-test developers succeed in their efforts, it would represent yet another tectonic shift for medical pathology laboratories. Clinical laboratory managers and stakeholders should be ready, for the words of the ancient Greek philosopher Heraclitus have never been truer: “Change is the only constant in life.”
Chronic disease monitoring at home has become a boon to patients as well as hospitals that are finding cost savings in programs designed to monitor/treat patients at external locations
Many clinical pathologists and medical laboratory scientists will be wary about the news that a California company wants to have cancer patients do their own CBCs at home, and that a device to enable such testing is being prepped to go through the FDA clearance process.
Home-based medicine care and chronic disease therapy treatments are gaining in popularity. Patients, understandably, would prefer to stay in the comfort of their homes then be exposed to stressful, germ-laden healthcare environments. And healthcare providers are finding cost savings in home-healthcare programs, which Dark Daily recently reported.
However, each new breakthrough in home medical care impacts clinical laboratories when specimen collection, near-patient medical laboratory testing, and therapy administration/monitoring shifts from traditional healthcare environments to home settings.
Nevertheless, new devices that enable chronic disease patients to monitor and report findings to care providers continue to be developed and embraced by healthcare consumers.
Complete Blood Count at Home
One such device from Athelas, a diagnostic test developer based in Mountain View, Calif., makes it easier and less expensive for patients undergoing cancer therapy to monitor their complete blood counts (CBC) at home without the need to travel to a doctor or medical laboratory to have the blood work performed, Medgadget reported. The device, which is undergoing the FDA Class 2 clearance process, enables patients to test their complete blood count (CBC) in the privacy of their own homes and report the results to their oncologists.
Athelas co-founders Tanay Tandon (left) and Deepika Bodapati (right) secured $3.7 million in funding from Sequoia Capital, Y Combinator, and NVIDIA, to produce their blood analysis device. (Photo copyright: Sina.)
To use the Athelas device, patients perform a simple finger prick and place a drop of blood on a proprietary testing strip. The strip is then inserted into the device where the blood is analyzed. Patients can view their lab-grade blood test results in about a minute.
Information gathered by the device can be sent to Android or iOS devices/apps and also to the patient’s doctor. The process allows patients and their doctors to receive frequent updates for monitoring treatments and disease progression and precisely observe changes in immune health.
According to Athelas, in about 60 seconds the blood analyzer provides accurate reading for:
“Athelas is bringing cancer patients a quick and reliable way to test their blood levels from within their home,” noted Alfred Lin, partner at Sequoia, in a statement. “Their new platform empowers patients to confidently monitor their condition and will cut down on unnecessary urgent care visits. We believe in Tanay and Deepika’s bold vision to transform at-home blood tests into an easy and accurate diagnostics tool that’s as trusted as a thermometer.”
The home-testing platform will cost consumers $20 per month, which Athelas hopes will eventually be covered by insurance companies.
Additional Benefits to At-Home Monitoring
The Athelas device also has functions beyond chronic disease monitoring. It can be used to determine if a viral or bacterial infection is present in an individual. In addition, the company is currently testing the machine with 100 patients at risk for a cardiac event to evaluate whether or not it can predict such an event days before it occurs.
“There’s a lot of research out there that shows inflammatory markers inside your own body will spike a couple days in advance,” Tandon told TechCrunch.
In the video above, Deepika Bodapati, co-founder of Athelas, describes how the diagnostic device operates. Click on the image above to view the video. (Video copyright: TechCrunch.)
The Athelas device is not yet cleared to market by the Food and Drug Administration (FDA) and more clinical research may be needed to validate the efficacy of the product. Athelas is currently loaning the device to cancer patients for the purpose of monitoring their chemotherapy progress, and is conversing with healthcare professionals, hospitals, and pharmaceutical companies regarding the benefits of the device.
Other CBC Devices
In 2017, Sysmex America announced it had received clearance from the FDA for the Sysmex XW-100 hematology analyzer, the first CBC system that allows in-house staff to perform CBC tests at Clinical Laboratory Improvement Amendments (CLIA)-waived locations. The Dark Report reported on this last year. (See TDR, “FDA Clears Waived CBC For Near-Patient Testing,” November 20, 2017.”
The XW-100 device enables physicians to perform in-office blood tests and receive results in as little as three minutes. This allows treatment plans to be initiated without interacting with clinical laboratories, which clearly impacts test ordering and lab revenue.
At-home and onsite blood testing devices serve an important role in patient care and provide healthcare professionals with expeditious and convenient test results. However, with the arrival of these new technologies, clinical laboratories will need to find new ways to bring value to physicians who employ them in their offices.
