Bacteria could become new biomarker for testing patients’ reaction to cancer treatments which would give microbiologists and clinical laboratories a new tool for aiding diagnosis and in the selection of appropriate therapies
In a surprising study conducted at King’s College London and Guy’s and St Thomas’ NHS Foundation Trust, British scientists have discovered that a common bacteria found in the mouth may be able to “melt” certain cancers. The bacteria could also be used as a clinical laboratory biomarker to determine how patients may react to specific cancer treatments.
The researchers found that the presence of Fusobacterium can help neutralize head and neck cancers and provide better outcomes in patients with those diseases, according to a Kings College London news release.
“In essence, we found that when you find these bacteria within head and neck cancers, [patients] have much better outcomes,” said Miguel Reis Ferreira, MD, PhD, clinical oncologist at Guy’s and St Thomas’, adjunct senior clinical lecturer at King’s College London and senior author of the study, in the news release. “The other thing that we found is that in cell cultures this bacterium is capable of killing cancer.”
“This research reveals that these bacteria play a more complex role than previously known in their relationship with cancer—that they essentially melt head and neck cancer cells,” said Miguel Reis Ferreira, MD, PhD (above), clinical oncologist at Guy’s and St Thomas’, adjunct senior clinical lecturer at King’s College London and senior author of the study, in a news release. “However, this finding should be balanced by their known role in making cancers such as those in the bowel get worse.” Should these findings prove sound, clinical laboratories may soon have a new biomarker for testing patients’ reaction to cancer treatments.

Researchers Surprised by Their Findings
The researchers began their research by using computer modeling to identify the types of bacteria to further scrutinize. They then studied the effect of those bacteria on cancer cells by analyzing data on 155 head and neck cancer patients whose tumor information had been submitted to the Cancer Genome Atlas. Head and neck cancers include cancers of the mouth, throat, voice box, nose, and sinuses.
The scientists placed Fusobacterium in petri dishes and kept the bacteria there for a few days. They observed the effect of that bacteria on head and neck cancers and discovered there was a 70% to 90% reduction in the number of viable cancer cells after being infused with the Fusobacterium.
Due to the known correlation between Fusobacterium and colorectal cancer, the team was astonished to find the cancer cells present in head and neck cancers had almost been eradicated.
In the news release, Ferreira said the researchers initially expected the Fusobacterium to boost the growth of the cancers and render those cancers more resistant to treatments like radiotherapy. However, they found the opposite to be true.
“The research in colorectal cancer indicates that these bacteria are bad, and that was kind of ingrained into our minds, and we were expecting to find the same thing,” said Ferreira in a Press Association (PA) interview, The Independent reported. “When we started finding things the other way around, we were brutally surprised.”
Predicting Better Outcomes, Lower Risk of Death
“You put it in the cancer at very low quantities and it just starts killing it very quickly,” Ferreira said in the King’s College London news release. “What we’re finding is that this little bug is causing a better outcome based on something that it’s doing inside the cancer. So we are looking for that mechanism at present, and it should be the theme for a new paper in the very short-term future.”
In addition, the scientists discovered that patients with Fusobacterium within their cancer showed improved survival rates when compared to those without the bacteria. The presence of the bacteria correlated with a 65% reduction in death risk.
“What it could mean is that we can use these bacteria to better predict which patients are more likely to have good or worse outcomes, and based on that, we could change their treatment to make it kinder in the patients that have better outcomes or make it more intense in patients that are more likely to have their cancers come back,” said Ferreira in the PA interview.
“Our findings are remarkable and very surprising. We had a eureka moment when we found that our international colleagues also found data that validated the discovery,” said Anjali Chander, PhD student, senior clinical research fellow, Comprehensive Cancer Center, King’s College London, and lead author of the study in the news release.
More to Learn about Bacteria as Biomarkers
According to the National Cancer Institute (NCI), more than 71,000 people will be diagnosed with one of the major types of head and neck cancer this year in the US and more than 16,000 patients will die from these diseases.
The Global Cancer Observatory (GLOBOCAN) estimates there are about 900,000 new cases of head and neck cancers diagnosed annually worldwide with approximately 450,000 deaths attributed to those cancers every year. GLOBOCAN also claims head and neck cancers are the seventh most common cancer globally.
More research and studies are needed to confirm the virtue of this latest venture into the human microbiome. However, the preliminary results of this study appear promising.
The study of human microbiota continues to bring unexpected surprises, as scientists gain more insights and identify specific strains of bacteria that may have a positive or negative influence on an individual’s health. These discoveries may give microbiologists and clinical laboratories intriguing new biomarkers that could be incorporated into medical tests that aid diagnosis and the selection of appropriate therapies.
Clinical laboratories will need new methods for accommodating the increase in senior patients seeking rapid access to medical laboratory testing and pathology services
Experts within the healthcare industry are predicting existing care delivery models will need to be revised within the next few years to accommodate a rapidly aging population dubbed a “silver tsunami.” Many hospital systems are actively taking steps to prepare for this coming sharp increase in the number of senior citizens needing healthcare services, including clinical laboratory testing.
Multi-hospital health systems will have to accommodate demand for healthcare delivered in ways that meet the changing expectations of seniors. These include rapid access to clinical laboratory testing and anatomic pathology services, electronic health records, and telehealth visits with their doctors.
These trends will also require clinical laboratories to evolve in ways consistent with meeting both the volume of services/testing and improved levels of personal, speedy access to test results that seniors expect.
All of this is problematic given the current state of hospital staff shortages across the nation.
Investopedia defines the term “silver tsunami” as “the demographic shift caused by the increasing number of older adults in society, led by the baby boom generation.”
Baby boomers are individuals who were born between 1946 and 1964. The US Census Bureau estimates there are 76.4 million baby boomers living in the country today, and that by 2030 all boomers will be 65 years of age or older.
“In the next five years, the most significant disruptor to healthcare will be the capacity challenges associated with the ‘silver tsunami’ of baby boomers hitting the age of healthcare consumption,” said Jonathan Washko, MBA, FACPE, NRP, AEMD (above), director at large, National Association of Emergency Medical Technicians (NAEMT) and assistant vice president, CEMS Operations, in an interview with Becker’s Hospital Review. Clinical laboratories will have to engage with these senior patients in new ways that fit their lifestyles. (Photo copyright: EMS1.)
Silver Tsunami Could Transform Healthcare
Approximately 10,000 people turn 65 in the US every day, making them eligible for Medicare. This increase in recipients is likely to strain the government system. Healthcare organizations are seeking new ways to prepare for the anticipated boost in seniors requiring health services.
Washko believes the population shift will cause healthcare leaders to develop novel care models based on “intelligent and intentional design for better outcomes, lower costs, and faster results,” Becker’s Hospital Review reported.
“Solutions will require shifts to care in the home, new operational care models, and technology integration,” Washko noted. “These will allow the medicine being delivered to be effectively and efficiently optimized, vastly improving the productivity of existing and net new capacity.”
A recent HealthStream blog post outlined some of the methods hospitals can use to adapt to an aging population. They include:
Facility Design: Modifying lighting, using large-print signage, providing reading glasses and hearing amplifiers, purchasing taller chairs with arms and lower examination tables.
Technology: Offering assistive devices, creating more telehealth options, developing more user-friendly websites and electronic medical records.
Healthcare Delivery: Training staff on geriatric care, offering services intended for an older population, such as geriatric psychology, fall prevention programs, and establishing a more patient-centered environment.
“Anticipated regulatory challenges post-election will influence healthcare operations. The looming recession may alter how individuals access healthcare and treatment based on affordability,” Shelly Schorer, CFO CommonSpirit Health, told Becker’s Hospital Review. “Despite these headwinds and challenges, at CommonSpirit we are prepared to pivot and meet the changing needs of our communities by accurately predicting and addressing their healthcare needs efficiently.”
“This represents the greatest market disruption on the near-horizon,” said Ryan Nicholas, MD, Chief Quality Officer at Mercy Medical Group. “This has prompted Mercy Medical Group to move rapidly into value-based care with focus on total cost of care and network integrity.”
Nichols told Becker’s Hospital Review that Mercy’s Medicare population has increased by 24% over the last year, and that Mercy is anticipating a growth of 28% over the next year. These increases have convinced the organization to shift its view of service functions and to invest in additional resources that meet the growing demands for senior healthcare.
“Expanding ambulatory services and improving access for primary care services to reduce unnecessary [emergency department] utilization and shorten length of stay is our top priority,” Nichols said.
Shifting Demand for Clinical Laboratory Testing
This is not the first time Dark Daily has covered how shifting demographics are changing the landscape of healthcare services in nations where populations are aging faster than babies are being born.
Thus, many healthcare organizations are taking a proactive approach to the expected increase in seniors needing care for age-related and chronic illnesses.
“This along with other risk and value-based models will continue to drive integration of healthcare services and the value proposition through improving quality while reducing costs,” Alon Weizer, MD, chief medical officer and senior vice president, Mount Sinai Medical Center, Miami Beach, Fla., told Becker’s Hospital Review. “While we are investing heavily to be successful in these models through primary care expansion and technology that will help reduce the need for acute care services, we continue to focus our culture on providing safe and high quality care to our patients.”
Clinical laboratories will need to adapt to the changing needs of older patients to ensure all people receive high quality care. The coming “silver tsunami” will require labs to evolve in ways consistent with meeting the growing needs of seniors and providing better levels of personal services and access to cost-effective, fast, and accurate lab testing.
Study findings could lead to new clinical laboratory screening tests that determine risk for cancer
New disease biomarkers generally lead to new clinical laboratory tests. Such may be the case in an investigational study conducted at the University of Oxford in the United Kingdom (UK). Researchers in the university’s Cancer Epidemiology Unit (CEU) have discovered certain proteins that appear to indicate the presence of cancer years before the disease is diagnosed.
The Oxford scientists “investigated associations between 1,463 plasma proteins and 19 cancers, using observational and genetic approaches in participants of the UK Biobank. They found 618 protein-cancer associations and 317 cancer biomarkers, which included 107 cases detected over seven years before the diagnosis of cancer,” News Medical reported.
To conduct their study, the scientists turned to “new multiplex proteomics techniques” that “allow for simultaneous assessment of proteins at a high-scale, especially those that remain unexplored in the cancer risk context,” News Medical added.
Many of these proteins were in “blood samples of people who developed cancer more than seven years before they received a diagnosis,” an Oxford Population Health news release notes.
“To be able to prevent cancer, we need to understand the factors driving the earliest stages of its development. These studies are important because they provide many new clues about the causes and biology of multiple cancers, including insights into what’s happening years before a cancer is diagnosed,” said Ruth Travis, BA, MSc, DPhil, senior molecular epidemiologist at Oxford Population Health and senior study author, in the news release.
“We now have technology that can look at thousands of proteins across thousands of cancer cases, identifying which proteins have a role in the development of specific cancers and which may have effects that are common to multiple cancer types,” said Ruth Travis, BA, MSc, DPhil (above), senior molecular epidemiologist, Oxford Population Health, in a news release.

Proteomics to Address Multiple Cancers Analysis
In their published paper, the Oxford scientists acknowledged other research that identified links between blood proteins and risk for various cancers, including breast, colorectal, and prostate cancers. They saw an opportunity to use multiplex proteomics methods for the simultaneous measurement of proteins “many of which have not previously been assessed for their associations with risk across multiple cancer sites,” the researchers noted.
The researchers described “an integrated multi-omics approach” and the use of the Olink Proximity Extension Assay (PEA) to quantify 1,463 proteins in blood samples from 44,645 participants in the UK Biobank, a large biomedical database and resource to scientists.
Olink, a part of Thermo Fisher Scientific in Waltham, Mass., explains on its website that PEA technology “uniquely combines specificity and scalability to enable high-throughput, multiplex protein biomarker analysis.”
The researchers also compared proteins of people “who did and did not go on to be diagnosed with cancer” to determine differences and identify proteins that suggest cancer risk, News Medical reported.
Proteins Could Assist in Cancer Prevention
“To save more lives from cancer, we need to better understand what happens at the earliest stages of the disease. Data from thousands of people with cancer has revealed really exciting insights into how the proteins in our blood can affect our risk of cancer. Now we need to study these proteins in depth to see which ones could be reliably used for cancer prevention,” Keren Papier, PhD, senior nutritional epidemiologist at Oxford Population Health and joint lead author of the study, told News Medical.
While further studies and regulatory clearance are needed before the Oxford researchers’ approach to identifying cancer in its early stages can be used in patient care, their study highlights scientists’ growing interest in finding biomarker combinations that can predict or diagnose cancer even when it is presymptomatic. By focusing on proteins rather than DNA and RNA, researchers are turning to a source of information other than human genes.
For anatomic pathologists and clinical laboratory leaders, the Oxford study demonstrates how scientific teams are rapidly developing new knowledge about human biology and proteins that are likely to benefit patient care and diagnostics.
List also includes precision oncology, liquid biopsies, and early diagnosis of pancreatic cancer
Pathologists and clinical laboratory managers will be interested to learn that in a recently updated article the World Economic Forum (WEF) identified a dozen important recent breakthroughs in the ongoing fight to defeat cancer, including some related to pathology and clinical laboratory diagnostics.
The article noted that approximately 10 million people die each year from cancer. “Death rates from cancer were falling before the pandemic,” the authors wrote. “But COVID-19 caused a big backlog in diagnosis and treatment.”
The Swiss-based non-profit is best known for its annual meeting of corporate and government leaders in Davos, Switzerland. Healthcare is one of 10 WEF “centers” focusing on specific global issues.
Here are four advances identified by WEF that should be of particular interest to clinical laboratory leaders. The remaining advances will be covered in part two of this ebrief on Wednesday.
“Our study represents a major leap in cancer screening, combining the precision of protein-based biomarkers with the efficiency of sex-specific analysis,” said Novelna founder and CEO Ashkan Afshin, MD, ScD (above), in a company press release. “We’re not only looking at a more effective way of detecting cancer early but also at a cost-effective solution that can be implemented on a large scale.” The 12 breakthroughs listed in the World Economic Forum’s updated article will likely lead to new clinical laboratory screening tests for multiple types of cancer.

Novelna’s Early-Stage Cancer Test
Novelna, a biotech startup in Palo Alto, Calif., says it has developed a clinical laboratory blood test that can detect 18 early-stage cancers, including brain, breast, cervical, colorectal, lung, pancreatic, and uterine cancers, according to a press release.
In a small “proof of concept” study, scientists at the company reported that the test identified 93% of stage 1 cancers among men with 99% specificity and 90% sensitivity. Among women, the test identified 84% of stage 1 cancers with 85% sensitivity and 99% specificity.
The researchers collected plasma samples from 440 individuals diagnosed with cancers and measured more than 3,000 proteins. They identified 10 proteins in men and 10 in women that correlated highly with early-stage cancers.
“By themselves, each individual protein was only moderately accurate at picking up early stage disease, but when combined with the other proteins in a panel they were highly accurate,” states a BMJ Oncology press release.
The company says the test can be manufactured for less than $100.
“While further validation in larger population cohorts is necessary, we anticipate that our test will pave the way for more efficient, accurate, and accessible cancer screening,” said Novelna founder and CEO Ashkan Afshin, MD, ScD, in the company press release.
Precision Oncology
According to the National Institutes of Health’s “Promise of Precision Medicine” web page, “Researchers are now identifying the molecular fingerprints of various cancers and using them to divide cancer’s once-broad categories into far more precise types and subtypes. They are also discovering that cancers that develop in totally different parts of the body can sometimes, on a molecular level, have a lot in common. From this new perspective emerges an exciting era in cancer research called precision oncology, in which doctors are choosing treatments based on the DNA signature of an individual patient’s tumor.”
“These advanced sequencing technologies not only extend lifespans and improve cure rates for cancer patients through application to early screening; in the field of cancer diagnosis and monitoring they can also assist in the formulation of personalized clinical diagnostics and treatment plans, as well as allow doctors to accurately relocate the follow-up development of cancer patients after the primary treatment,” Wang wrote.
Based in China, Genetron Health describes itself as a “leading precision oncology platform company” with products and services related to cancer screening, diagnosis, and monitoring.
Liquid and Synthetic Biopsies
Liquid biopsies, in which blood or urine samples are analyzed for presence of biomarkers, provide an “easier and less invasive” alternative to conventional surgical biopsies for cancer diagnosis, the WEF article notes.
These tests allow clinicians to “pin down the disease subtype, identify the appropriate treatment and closely track patient response, adjusting course, if necessary, as each case requires—precision medicine in action,” wrote Merck Group CEO Belén Garijo, MD, in an earlier WEF commentary.
The WEF article also highlighted “synthetic biopsy” technology developed by Earli, Inc., a company based in Redwood City, Calif.
As explained in a Wired story, “Earli’s approach essentially forces the cancer to reveal itself. Bioengineered DNA is injected into the body. When it enters cancer cells, it forces them to produce a synthetic biomarker not normally found in humans.”
The biomarker can be detected in blood or breath tests, Wired noted. A radioactive tracer is used to determine the cancer’s location in the body.
“Pancreatic cancer is one of the deadliest cancers,” the WEF article notes. “It is rarely diagnosed before it starts to spread and has a survival rate of less than 5% over five years.”
The test is based on a technology known as high-conductance dielectrophoresis (DEP), according to a UC San Diego press release. “It detects extracellular vesicles (EVs), which contain tumor proteins that are released into circulation by cancer cells as part of a poorly understood intercellular communication network,” the press release states. “Artificial intelligence-enabled protein marker analysis is then used to predict the likelihood of malignancy.”
The test detected 95.5% of stage 1 pancreatic cancers, 74.4% of stage 1 ovarian cancers, and 73.1% of pathologic stage 1A lethally aggressive serous ovarian adenocarcinomas, they wrote.
“These results are five times more accurate in detecting early-stage cancer than current liquid biopsy multi-cancer detection tests,” said co-senior author Scott M. Lippman, MD.
Look to Dark Daily’s ebrief on Wednesday for the remainder of breakthroughs the World Economic Forum identifies as top advancements in the fight to defeat cancer.
Underfunding of clinical laboratories has led to similar worker walkouts in multiple Australasian nations
Once again, cuts in government spending on pathology services has forced healthcare workers to walk off the job in Australia. This is in line with other pathology doctor and clinical laboratory workers strikes in New Zealand and other Australasian nations over the past few years.
Announcement of a planned closure of the pathology laboratory at 30-bed Cootamundra Hospital in Australia to make room for expanding the emergency department spurred the health worker walkouts.
“Health staff from Cootamundra Hospital, alongside pathology workers from Deniliquin, Tumut, Griffith, Wagga Wagga, and Young will rally in front of their respective facilities” to draw attention to the effect closing the lab would have on critical healthcare services across those areas, Region Riverina reported.
The strikes are drawing attention to unfair pay and poor working conditions that underfunding has brought to the state-run healthcare systems in those nations. They also highlight how clinical laboratories worldwide are similarly struggling with facility closings, unfair pay, and unachievable workloads.
“The proposed closure of Cootamundra’s pathology lab is a short-sighted decision that will have far-reaching consequences for patient care in the region,” NSW Health Services Union (HSU) Secretary Gerard Hayes (above) told Region Riverina. Similar arguments have been made for years concerning the underfunding, pay disparities, and poor working conditions in New Zealand’s government-run clinical laboratories and pathology practices that has led to worker strikes there as well.

Australia Pathology Lab Closure Stokes Fears
Cootamundra Hospital’s strike was spurred by a planned closure of its pathology laboratory. In May, employees learned of the plans to close the lab as well as surgery and birthing centers to accommodate expansion of the emergency department, Region Riverina reported.
“Pathology workers are already in short supply and this move could see us lose highly skilled professionals from the NSW Health system altogether,” New South Wales (NSW) Health Services Union (HSU) Secretary Gerard Hayes told Region Riverina.
The cuts would not only be detrimental to the area, it would significantly affect patient care, he added.
“This lab is not just profitable; it’s a vital lifeline for Cootamundra Hospital’s [surgical] theater lists and maternity unit,” he said. “Without this lab, patients will face significantly longer wait times for life-saving diagnostic information. This delay could severely impact our ability to provide timely care, especially in emergencies.”
Echoing those sentiments, HSU Union Official Sam Oram told Region Riverina that closing the Cootamundra Hospital lab would put pressure on labs in Wagga and Young and would continue a trend of closing smaller pathology labs. Oram, who organizes for members in Canberra and Murrumbidgee Local Health District, noted that smaller labs in Tumut and Deniliquin could be in danger as well.
“Why should people living in rural and regional areas have fewer and inferior services to Australians living in metropolitan areas?” Michael McCormack, MP, Federal Member for Riverina and former deputy prime minister of Australia, asked Parliament in June, Region Riverinareported. “There’s no right or proper answer to that question. They simply should not,” he added.
Tasmania’s Troubles
Medical scientists recently walked off the job at Launceston General Hospital in Tasmania, Australia, to protest “the government’s ‘inaction’ on recruiting more staff,” according to Pulse Tasmania. The hospital’s lab has a staff shortage of 17 employees, requiring the remaining staff members to handle a much increased workload, Ryan Taylor, a medical laboratory scientist with the Tasmanian Department of Health, told Pulse Tasmania.
“This shortfall is leading to significant and unacceptable challenges … which are causing the Tasmanian community from receiving vital test results that are essential for their health,” Lucas Digney, Industrial Champion, Health and Community Services Union (HACSU) leader, told Pulse Tasmania.
New Zealand Struggles with Its Healthcare Workers
Aotearoa, as New Zealand is known by its indigenous Polynesian population, also struggles with health worker walkouts.
“Medical labs are an essential organ of the health system. Many were stupidly privatized years ago, others still operate within Te Whatu Ora [aka Health New Zealand, the publicly funded healthcare system] with all the resource shortages and stress that go with that,” Newsroom said of the country’s plight in 2023. “There was a view that competition in medical labs would produce greater efficiency, but it has actually produced a mess.”
Dark Daily has covered the ongoing strife in New Zealand’s clinical laboratories over many years. Previous ebriefs highlighted how the strikes were causing delays in critical clinical laboratory blood testing and surgical procedures.
Underfunding in clinical laboratories continues to cause work stoppages in the Australasian countries. But as Dark Daily readers know, it is a growing problem among European nations and in the United States as well.
Patients outside the US wait even longer to see healthcare specialists with some appointments scheduled a year out in the Canadian province of Nova Scotia
Data recently released by healthcare consulting firm ECG Management Consultants (ECG) reveals that patients in the United States wait an average of 38 days for healthcare appointments. That figure is a significant stretch from the desired industry standard of 14-day or less wait times, according to Becker’s Hospital Review.
Clinical laboratories serve the needs of physicians who see patients and refer testing needed by patients to labs. Thus, average wait times should be of interest to lab professionals who strive to meet reporting turnaround times for lab test results, particularly given the unique way that ECG conducted its survey of patient wait times.
In “The Waiting Game: New-Patient Appointment Access for US Physicians,” ECG wrote, “Adopting a ‘secret shopper’ approach, we put ourselves in the shoes of the average patient trying to book an appointment. We contacted nearly 4,000 physician practices in 23 major cities across the US, posing as a new, commercially insured patient seeking care for general, nonemergent conditions that typically don’t require a physician referral.”
ECG’s study provides “a realistic view of where and in what specialties patients face the most significant challenges to accessing routine care,” the authors wrote in their published report. The report also includes patients’ appointment-keeping behavior based on length of wait times.
“Consumer expectations have evolved significantly in all industries. From buying a plane ticket to making a restaurant reservation, the consumer experience has been highly optimized and customers in turn have become accustomed to information and services being available at their fingertips. They bring the same expectations about speed and convenience to healthcare,” the researchers explained.
ECG pointed out that when patients are required to wait 14 days or more to see their physicians, no shows and cancellations increase dramatically.
“Numerous studies have shown that patients are significantly less likely to show up for appointments that are scheduled further out,” the study authors noted.
“One of the takeaways was how difficult the patient experience is. Not only did our secret shoppers have to go out and find physicians, they had to sit on the phone sometimes on very long holds and go through multiple barriers and jump through hoops,” Jennifer Moody (above), partner with ECG Management Consultants and one of the authors of the study, told Becker’s Hospital Review. “Even in that case, they weren’t successful in scheduling appointments with all the practices they called. I think of the average consumer who might be having a similar experience,” she added. Lengthy wait times are not believed to be an issue when patients need clinical laboratory tests.

Getting Authentic Results
To gather the study data, ECG distributed its secret shoppers throughout 23 major US cities, reaching almost 4,000 physician practices (between 145-168 per city) to schedule appointments for non-emergency conditions not needing a physical referral.
The researchers gathered wait times for TNAAs (third next available appointments), a common metric. They chose TNAAs because first and second appointments often produce unclear results due to extenuating circumstances or late cancellations, Becker’s Hospital Review reported.
The researchers recorded TNAAs for the following specialties:
Cardiology (39 days),
Dermatology (40 days),
Family medicine (29 days),
Gastroenterology (48 days),
General surgery (22 days),
Neurology (63 days),
Obstetrics/gynecology (37 days),
Ophthalmology (37 days),
Orthopedic surgery (20 days),
Pediatrics (24 days), and,
Rheumatology (68 days).
They found the average wait time to be 38 days. And “of the 253 metropolitan market and specialty combinations included in this research, only 6% had an average wait time of 14 days or less,” Becker’s reported.
The researchers omitted the physician practices that were unable to either take or return calls, take messages, or provide a hold time under five minutes to give the secret shopper an answer, Becker’s added.
Jennifer Moody, Partner, ECG Management Consultants, one of the authors of the study, “was particularly surprised by the portion of callers who never even made it to the stage of learning about wait times. Out of 3,712 physician practices, callers were able to secure responses from only 3,079, meaning nearly one in five physician practices could not provide appointment availability information,” Becker’s reported.
The lowest average wait time in all specialties was 27 days in Houston, and the longest was 70 days in Boston. “A key takeaway from the report is that physician concentration does not guarantee timely access, as a major healthcare hub like Boston helps illustrate,” Becker’s noted, adding that physicians in such areas may “devote time to teaching or research over appointments.”

Other Country’s Wait Times
Healthcare systems outside the US struggle with patient wait times as well. Forbes reported that patients of Canada’s public health system “faced a median wait of 27.7 weeks for medically necessary treatment from a specialist after being referred by a general practitioner. That’s over six months—the longest ever recorded.”
Patients in Nova Scotia wait even longer. There they “face a median wait of 56.7 weeks—more than a year—for specialist treatment following referral by a general practitioner. Those on Prince Edward Island are also in the year-long waiting club—a median of just over 55 weeks,” Forbes noted.
And in the UK, a recent survey found that “more than 150,000 patients had to wait a day in A&E [accident and emergency] before getting a hospital bed last year, according to new data,” with the majority of those patients over the age of 65, according to The Guardian.
ECG suggestions that may reduce wait times include:
Adopt automation and self-service tools in an “easily navigable platform” that enables patients to schedule appointments 24/7.
Ensure healthcare providers are “utilized appropriately and at the top of their license.”
Address inequities in access to healthcare regardless of patients’ location or socioeconomic status.
There is more in the ECG report that hospitals—as well as clinical laboratories—can use to reduce patient wait times to see care providers. As the authors wrote, “For patients, the first step of the care journey shouldn’t be the hardest.”
