Media reports in the United Kingdom cite bad timing and centralization of public health laboratories as reasons the UK is struggling to meet testing goals
Clinical pathologists and medical laboratories in UK and the US function within radically different healthcare systems. However, both countries faced similar problems deploying widespread diagnostic testing for SARS-CoV-2, the novel coronavirus that causes COVID-19. And the differences between America’s private healthcare system and the UK’s government-run, single-payer system are exacerbating the UK’s difficulties expanding coronavirus testing to its citizens.
The Dark Daily reported in March that a manufacturing snafu had delayed distribution of a CDC-developed diagnostic test to public health laboratories. This meant virtually all testing had to be performed at the CDC, which further slowed testing. Only later that month was the US able to significantly ramp up its testing capacity, according to data from the COVID Tracking Project.
However, the UK has fared even worse, trailing Germany, the US, and other countries, according to reports in Buzzfeed and other media outlets. On March 11, the UK government established a goal of administering 10,000 COVID-19 tests per day by late March, but fell far short of that mark, The Guardian reported. The UK government now aims to increase this to 25,000 tests per day by late April.
This compares with about 70,000 COVID-19 tests per day in
Germany, the Guardian reported, and about 130,000 per day in the US
(between March 26 and April 14), according to the COVID Tracking Project.
What’s Behind the UK’s Lackluster COVID-19 Testing
Response
In January, when the outbreak first hit, Public Health England (PHE) “began a strict program of contact tracing and testing potential cases,” Buzzfeed reported. But due to limited medical laboratory capacity and low supplies of COVID-19 test kits, the government changed course and de-emphasized testing, instead focusing on increased ICU and ventilator capacity. (Scotland, Wales, and Northern Ireland each have separate public health agencies and national health services.)
Later, when the need for more COVID-19 testing became
apparent, UK pathology laboratories had to contend with global shortages of
testing kits and chemicals, The Guardian reported. At present, COVID-19 testing
is limited to healthcare workers and patients displaying symptoms of pneumonia,
acute
respiratory distress syndrome, or influenza-like illness, PHE stated in “COVID-19:
Investigation and Initial Clinical Management of Possible Cases” guidance.
Another factor that has limited widespread COVID-19 testing is the country’s highly-centralized system of public health laboratories, Buzzfeed reported. “This has limited its ability to scale and process results at the same speed as other countries, despite its efforts to ramp up capacity,” Buzzfeed reported. Public Health England, which initially performed COVID-19 testing at one lab, has expanded to 12 labs. NHS laboratories also are testing for the SARS-CoV-2 coronavirus, PHE stated in “COVID-19: How to Arrange Laboratory Testing” guidance.
Sharon Peacock, PhD, PHE’s National Infection Service Interim Director, Professor of Public Health and Microbiology at the University of Cambridge, and honorary consultant microbiologist at the Cambridge clinical and public health laboratory based at Addenbrookes Hospital, defended this approach at a March hearing of the Science and Technology Committee (Commons) in Parliament.
“Laboratories in this country have largely been merged, so we have a smaller number of larger [medical] laboratories,” she said. “The alternative is to have a single large testing site. From my perspective, it is more efficient to have a bigger testing site than dissipating our efforts into a lot of laboratories around the country.”
Writing in The Guardian, Paul Hunter, MB ChB MD, a microbiologist and Professor of Medicine at University of East Anglia, cites historic factors behind the testing issue. The public health labs, he explained, were established in 1946 as part of the National Health Service. At the time, they were part of the country’s defense against bacteriological warfare. They became part of the UK’s Health Protection Agency (now PHE) in 2003. “Many of the laboratories in the old network were shut down, taken over by local hospitals or merged into a smaller number of regional laboratories,” he wrote.
US Facing Different Clinical Laboratory Testing Problems
Meanwhile, a few medical laboratories in the US are now contending with a different problem: Unused testing capacity, Nature reported. For example, the Broad Institute of MIT and Harvard in Cambridge, Mass., can run up to 2,000 tests per day, “but we aren’t doing that many,” Stacey Gabriel, PhD, a human geneticist and Senior Director of the Genomics Platform at the Broad Institute, told Nature. Factors include supply shortages and incompatibility between electronic health record (EHR) systems at hospitals and academic labs, Nature reported.
Politico
cited the CDC’s narrow testing criteria, and a lack of supplies for collecting
and analyzing patient samples—such as swabs and personal protective equipment—as
reasons for the slowdown in testing at some clinical laboratories in the US.
Challenges Deploying Antibody Tests in UK
The UK has also had problems deploying serology tests designed to detect whether people have developed antibodies against the virus. In late March, Peacock told members of Parliament that at-home test kits for COVID-19 would be available to the public through Amazon and retail pharmacy chains, the Independent reported. And, Politico reported that the government had ordered 3.5 million at-home test kits for COVID-19.
However, researchers at the University of Oxford who had been charged with validating the accuracy of the kits, reported on April 5 that the tests had not performed well and did not meet criteria established by the UK Medicines and Healthcare products Regulatory Agency (MHRA). “We see many false negatives (tests where no antibody is detected despite the fact we know it is there), and we also see false positives,” wrote Professor Sir John Bell, GBE, FRS, Professor of Medicine at the university, in a blog post. No test [for COVID-19], he wrote, “has been acclaimed by health authorities as having the necessary characteristics for screening people accurately for protective immunity.”
He added that it would be “at least a month” before suppliers could develop an acceptable COVID-19 test.
In the United States, the Cellex COVID-19 test is intended for use by medical laboratories. As well, many research sites, academic medical centers, clinical laboratories, and in vitro diagnostics (IVD) companies in the US are working to develop and validate serological tests for COVID-19.
Within weeks, it is expected that a growing number of such
tests will qualify for a Food and Drug Administration (FDA) Emergency Use
Authorization (EUA) and become available for use in patient care.
Since Alexa is now programed to be compliant with HIPAA privacy rules, it’s likely similar voice assistance technologies will soon become available in US healthcare as well
Shortages of physicians and other types of caregivers—including
histopathologists
and pathology
laboratory workers—in the United Kingdom (UK) has the UK’s National Health Service (NHS) seeking alternate
ways to get patients needed health and medical information. This has prompted a
partnership with Amazon to use the Alexa virtual assistant to
answer patients healthcare inquiries.
Here in the United States, pathologists and clinical
laboratory executives should take the time to understand this development.
The fact that the NHS is willing to use a device like Alexa to help it maintain
access to services expected by patients in the United Kingdom shows how rapidly
the concept of “virtual clinical care” is moving to become mainstream.
If the NHS can make it work in a health system serving 66-million
people, it can be expected that health insurers, hospitals, and physicians in
the United States will follow that example and deploy similar virtual health
services to their patients.
For these reasons, all clinical laboratories and anatomic
pathology groups will want to develop a strategy as to how their
organizations will interact with virtual health services and how their labs
will want to deploy similar virtual patient information services.
Critical Shortages in Healthcare Services
While virtual assistants have
been answering commonly-asked health questions by mining popular responses on
the Internet for some time, this new agreement allows Alexa to provide
government-endorsed medical advice drawn from the NHS website.
By doing this, the NHS hopes to reduce the burden on
healthcare workers by making it easier for UK patients to access health
information and receive answers to commonly-asked health questions directly from
their homes, GeekWire
reported.
“The public needs to be able to get reliable information
about their health easily and in ways they actually use. By working closely
with Amazon and other tech companies, big and small, we can ensure that the
millions of users looking for health information every day can get simple,
validated advice at the touch of a button or voice command,” Matthew Gould, CEO of NHSX, a division of the NHS that focuses
on digital initiatives, told GeekWire.
The
Verge reported that when the British government officially announced
the partnership in a July press
release, the sample questions that Alexa could answer included:
Alexa, how do I treat a migraine?
Alexa, what are the symptoms of the flu?
Alexa, what are the symptoms of chickenpox?
“We want to empower every patient to take better control of
their healthcare and technology like this is a great example of how people can
access reliable, world-leading NHS advice from the comfort of their home,
reducing the pressure on our hardworking GPs (General Practitioners) and
pharmacists,” said Matt
Hancock, Secretary of State for Health and Social Care, in the press release.
MD
Connect notes that the NHS provides healthcare services free of charge to
more than 66-million individuals residing in the UK. With 1.2 million
employees, the NHS is the largest employer in Europe, according to The
Economist. That article also stated that the biggest problem facing the
NHS is a staff shortage, citing research conducted by three independent
organizations:
Their findings indicate “that NHS hospitals, mental-health
providers, and community services have 100,000 vacancies, and that there are
another 110,000 gaps in adult social care. If things stay on their current
trajectory, the think-tanks predict that there will be 250,000 NHS vacancies in
a decade,” The Economist reported.
“This idea is certainly interesting and it has the potential
to help some patients work out what kind of care they need before considering
whether to seek face-to-face medical help, especially for minor ailments that
rarely need a GP appointment, such as coughs and colds that can be safely
treated at home,” Professor
Helen Stokes-Lampard, Chairman at the Royal
College of General Practitioners, and Chair of the Board Of
Directors/Trustees at National
Academy of Social Prescribing, told Sky News.
“However,” she continued, “it is vital that independent
research is done to ensure that the advice given is safe, otherwise it could
prevent people seeking proper medical help and create even more pressure on our
overstretched GP service.”
Amazon has assured consumers that all data obtained by Alexa
through the NHS partnership will be encrypted to ensure privacy and security,
MD Connect notes. Amazon also promised that the personal information will not
be shared or sold to third parties.
Alexa Now HIPAA Compliant in the US
This new agreement with the UK follows the announcement in April
of a new Alexa
Skills Kit that “enables select Covered Entities and their Business
Associates, subject to the US Health
Insurance Portability and Accountability Act of 1996 (HIPAA), to build
Alexa skills that transmit and receive protected
health information (PHI) as part of an invite-only program. Six new Alexa
healthcare skills from industry-leading healthcare providers, payors, pharmacy
benefit managers, and digital health coaching companies are now operating in
our HIPAA-eligible environment.”
Developers of voice assistance technologies can freely use
these Alexa skills, which are “designed to help customers manage a variety of
healthcare needs at home simply using voice—whether it’s booking a medical
appointment, accessing hospital post-discharge instructions, checking on the
status of a prescription delivery, and more,” an Amazon
Developer Alexa blog states.
The blog lists the HIPAA-compliant Alexa skills as:
Express
Scripts: Members can check the status of a home delivery prescription and can
request Alexa notifications when their prescription orders are shipped.
Cigna
Health Today by Cigna (NYSE:CI): Eligible employees with one of Cigna’s
large national accounts can now manage their health improvement goals and
increase opportunities for earning personalized wellness incentives.
Swedish
Health Connect by Providence St.
Joseph Health, a healthcare system with 51 hospitals across seven states
and 829 clinics: Customers can find an urgent care center near them and
schedule a same-day appointment.
Atrium
Health, a healthcare system with more than 40 hospitals and 900 care
locations throughout North and South Carolina and Georgia: Customers in North
and South Carolina can find an urgent care location near them and schedule a
same-day appointment.
Livongo,
a digital health company that creates new and different experiences for people
with chronic conditions: Members can query their last blood sugar reading,
blood sugar measurement trends, and receive insights and Health Nudges that are
personalized to them.
HIPAA Journal notes: “This is not the first time that Alexa skills have been developed, but a stumbling block has been the requirements of HIPAA Privacy Rules, which limit the use of voice technology with protected health information. Now, thanks to HIPAA compliant data transfers, the voice assistant can be used by a select group of healthcare organizations to communicate PHI without violating the HIPAA Privacy Rule.”
Steady increases associated with the costs of medical care
combined with a shortage of healthcare professionals on both continents are
driving trends that motivate government health programs and providers to
experiment with non-traditional ways to interact with patients.
New digital and Artificial
Intelligence (AI) tools like Alexa may continue to emerge as methods for
providing care—including clinical laboratory and pathology advice—to healthcare
consumers.
Based on clinical trials of the medical laboratory test, pregnant women can expect a reduced risk for experiencing complications associated with the dangerous blood disorder
Clinical pathology laboratories and obstetricians in the UK may soon have a new blood test that can help provide earlier diagnoses of pre-eclampsia, a hypertensive disorder of pregnancy that can cause liver and kidney disfunctions and, if untreated, can lead to eclampsia and deadly seizures.
Following a clinical trial conducted by scientists at King’s College London (King’s College), the National Health Service (NHS) in the United
Kingdom (UK) announced it would be making the new test widely available.
The researchers published their findings in The
Lancet medical journal. Their paper explains that the clinical trial
took place in 11 maternity units in the UK from June 2016 through October 2017.
And that 1,023 women were divided into two groups:
576 (56%) were in the “intervention group,”
meaning they had PGF test results made available to their maternity teams;
447 (44%) did not have PGF test results made
available.
The researchers, the Independent
reported, wanted to determine the impact, if any, the new test’s results would
have on diagnoses.
Significantly Reduced Time to Diagnosis
Trial results indicated that measuring the placental growth factor (PGF) in women who are suspected of having pre-eclampsia can increase speed to diagnosis. “PGF testing was shown to reduce the average time to pre-eclampsia diagnosis from 4.1 days to 1.9 days, and serious complications before birth (such as eclampsia, stroke, and maternal death) [dropped] from 5% to 4%,” a King’s College press release stated.
“Complications like stroke, seizures and maternal death fell
by 20% when doctors had access to PGF testing,” the Independent
reported.
The researchers stated in their study, “Our trial has shown
that, in women presenting with suspected pre-eclampsia, PGF measurement,
incorporated into a management algorithm based on national guidelines,
significantly reduces the time taken for treating clinicians to diagnose
pre-eclampsia. This improvement was associated with a significant reduction in
maternal adverse outcomes, with no detected difference in gestational age at
delivery or adverse perinatal outcomes.”
The King’s College press release states, “Pre-eclampsia is
suspected in around 10% of UK pregnancies, affecting approximately 80,000 women
annually. If untreated, it can progress to cause complications in the woman,
including damage to vital organs, fits, and can be fatal for the woman and
baby. Globally, 100 women die as a result of the condition every day.”
The release also noted that “doctors were able to diagnose
pre-eclampsia on average two days sooner. This was associated with significant
improvements in outcomes for women without causing health problems for babies.”
Measuring PGF in Clinical Laboratory Study
PGF is a molecular marker for inflammation associated mostly
with the mother’s placenta.
The King’s College researchers wanted to find out if a quicker diagnosis of
pre-eclampsia was possible. And, if so, could it reduce adverse outcomes in the
mother and baby?
“For the last hundred years, we have diagnosed pre-eclampsia
through measuring blood pressure and checking for protein in a woman’s urine.
These are relatively imprecise and often quite subjective,” said Lucy Chappell, PhD,
NIHR Research Professor in Obstetrics at King’s College, and lead author of the
study, in the news release.
“We knew that monitoring PGF was an accurate way to help
detect the condition, but [we] were unsure whether making this tool available
to clinicians would lead to better care for women. Now we know that it does,” she
concluded.
Pre-eclampsia can lead to stroke, seizures, and even death
of expectant mothers and unborn children. It is usually diagnosed after 20
weeks of gestation through blood pressure tests and urine tests that show
hypertension and elevated protein levels.
“We found that the availability of PGF test results
substantially reduced the time to clinical confirmation of pre-eclampsia. Where
PGF was implemented, we found a lower incidence of maternal adverse outcomes,”
the researchers wrote in their study.
Similar Study in the US
In the UK, pre-eclampsia affects about one in 20 pregnancies
or 80,000 women each year, New
Scientist explained. While in the US, data compiled from the Centers for Disease Control
and Prevention (CDC) indicate that pre-eclampsia affects one in 25
pregnancies or about 154,220 women annually.
Researchers in Ohio also recently reported on a test and a piloted
clinical study for rapid diagnosis of pre-eclampsia.
“This is the first clinical study using the point-of-care,
paper-based Congo Red Dot (CRD) diagnostic test, and the mechanism proved
superior in establishing or ruling out a diagnosis of pre-eclampsia,” Kara Rood, MD, a maternal-fetal
medicine physician at Wexner Medical Center and first author of the study said
in the Wexner press release. “Our findings will have a huge impact on the
health of women and children.”
The researchers published their findings in EClinicalMedicine,
a Lancet Journal.
“Pre-eclampsia is often described as ‘mysterious’ because
it’s difficult to diagnose. Our researchers show that there’s an easy,
non-invasive test that will help diagnose this condition and maintain the
health of pregnant women and their babies,” K. Craig
Kent, MD, OSU Dean of the College of Medicine, said in the press release.
Clinical laboratory tests such as these being developed in
the US and abroad could help pregnant women worldwide experience happy
pregnancies and give birth to healthy babies. Medical laboratory leaders in
this country may want to stay abreast of the development of these simple blood
and urine tests.
Physicians in Saskatchewan called for changes after wait times for anatomic pathology test results reached six weeks or more
Anatomic pathologist and histopathologist shortages have plagued the single-payer healthcare systems in Canada and the United Kingdom (UK) in recent years. The consequence is increased wait times for physicians in both countries to receive medical laboratory test results, which increases wait times across the entire healthcare continuum.
However, one Canadian province significantly reduced a backlog that had pushed wait times for surgical pathology test results to six weeks or more. It did this by having its pathologists perform first-stage examinations normally completed by pathology assistants or medical technologists.
The Saskatchewan Health Authority (SHA) announced in October it had cleared nearly half of the 2,600-plus biopsies that were waiting to be processed at hospital labs in Regina and Saskatoon, the Regina Leader-Post reported.
“I think we’ve been making amazing progress in the work,” Lenore Howey, Executive Director of Laboratory Services at SHA, told the newspaper. “It’s always good to take time to know and understand your process, so that we can put the right resources in the right places.”
Getting Anatomic Pathologists Involved
Howey stated the SHA cleared cases by having pathologists “assist with the work in the first phase”—or gross examination stage—of a biopsy. This is the part of the process during which pathology assistants or medical laboratory technologists typically record the size, weight, and description of a specimen and look for pathological changes.
In addition, the SHA hired an additional pathologist assistant and three histology/cytology technologists—one on a permanent basis and two on a temporary basis. Other improvements include:
Working toward resolving problems with voice recognition transcription software being piloted in Regina for the gross examination phase of processing; and;
Implementing an electronic specimen tracking system in Saskatoon, which eventually also may be used in Regina.
Physicians Express Dissatisfaction with Wait Times
Physicians attending the Saskatchewan Medical Association’s Spring Representative Assembly in May raised the backlog issue with Health Minister Jim Reiter, complaining about the impact on patient care. At that point, the backlog of pathology cases had hit 1,662 in Regina, while Saskatoon’s caseload totaled 1,005. Many of these biopsies involve cancer patients, thus delaying a diagnosis and the start of an appropriate treatment for these patients.
“I’m trying to get things done as expeditiously as possible,” urologist Francisco Garcia, MD, told the Leader-Post, “but for the first five or six weeks, I’m handcuffed in terms of what I’m able to do.”
Now, thanks to SHA’s efforts, as of Oct. 2 specimens in progress dropped to 785 in Regina and 748 in Saskatoon. Both numbers are within range of SHA’s target of 750.
“We do not have a backlog right now,” Lenore Howey, Executive Director of Laboratory Services at SHA, told the Leader-Post. “Our system is very stable, but we do have checks and balances to put in place so that we would never get there again, which we didn’t have prior.” (Photo copyright: Saskatchewan Health Authority.)
Wait Times Impacting Patient Care Worldwide
While Saskatchewan appears to have solved its most recent pathology reporting issue, this is not the first time the province has dealt with delays in lab testing reports. In 2011, Dark Daily reported on lengthy turnaround times for anatomic pathology test reports that averaged more than 12 days, which was blamed on shortage of pathologists dating back to 2001. (See, “Pathologist Shortage and Delays in Lab Test Reports Get Publicity in Saskatchewan,” August 15, 2011.)
“Making sure pathology services can cope with current and future demand is essential if we are to ensure early diagnosis and improve outcomes for patients,” Jo Martin, PhD, President of the Royal College of Pathologists, told the BBC.
Increased workloads due to new NHS screening programs and an approaching retirement crisis—a quarter of all histopathologists in the UK are aged 55 or over—has caused the Royal College of Pathologists to call for more funded training places, better IT systems, and further investment in pathology services.
While the US healthcare system is not currently experiencing a shortage of clinical laboratory staff or anatomic pathologists, shortages in other countries illustrate the impact any delay in reporting results can have on patient care.
Only 3% of histopathology departments that responded to the Royal College of Pathologists’ workforce census reported enough staff to meet clinical demand
There is a chronic shortage of histopathologists in the United Kingdom (UK) and it is being blamed for cancer treatment waiting times that now reach the worst-ever levels, as National Health Service (NHS) training initiatives and other steps fail to keep pace with growing demand for diagnostic services.
For US anatomic pathologists and clinical laboratory managers, headlines from the UK reveal the impact a shortage of trained histopathologists (UK’s version of anatomic pathologists) and support technical staff can have on patient care when longer wait times for pathology support and diagnosis become the norm.
Royal College of Pathologists Report
The extent of the UK-wide histopathology staff shortages was highlighted in a recently released 2017 workforce census by the Royal College of Pathologists (RCPath). Of the 103 histopathology departments that responded to a survey, only 3% said they had enough staff to meet the current clinical demand! And 45% of departments had to outsource work, while half of the departments were forced to use more expensive temporary workers.
“The cost of staff shortages across histopathology departments is high for both patients and for our health services,” Jo Martin, PhD, President of the Royal College of Pathologists, noted in a statement announcing the survey results. “For patients, it means worrying delays in diagnosis and treatment. For NHS hospitals, it means spending more resources on [temporary] doctors to fill staffing gaps, or outsourcing services. We estimate this cost [to be] £27 million ($35.2 million) each year across the UK health service—money that could be better invested in staff and new diagnostic equipment.”
Royal College of Pathologists President Jo Martin, PhD, is calling on the National Health Service to take additional steps to increase the number of pathologists working in the United Kingdom, including more funded training places. That’s following the release of a Royal College of Pathologists workforce survey, which reported only 3% of histopathology departments in the UK have enough staff to meet clinical demand.

According to iNews, NHS England recorded its worst cancer treatment waiting times on record in July 2018, with more than 3,000 people waiting longer than two months for cancer treatment to begin. NHS’ target is for 85% of patients to begin cancer treatment within 62 days of being referred by their general practitioner.
Anatomic pathologists in the United States should consider how the UK’s average delay in starting cancer treatment affects patients in that country. It is a metric that patients in the US would not tolerate. However, in the UK’s single payer system, the government’s National Health Service sets the budgets for training new physicians, including histopathologists. For many years, the pathology profession in the UK has regularly advocated for increasing the number of histopathologists trained each year by the medical schools in that country.
In July, the number of patients waiting for treatment longer than 60 days fell to 78.2%, the 31st month in a row the target was breached, iNews reported.
“We know that histopathology consultant shortages contribute to at least part of that problem,” Martin told iNews.
The RCPath report highlights the intense pressures on histopathologists—most of whom working in understaffed laboratories—face from increased workloads, as new NHS cancer screening initiatives, an aging population, and a shift toward precision medicine result in a rising number of cases being referred to labs.
“Demand for pathology services has grown significantly in recent years and continues to grow,” Martin noted in the RCPath statement. “The pathology workforce has not increased in line with this demand. If this trend continues unchecked, clinical services could be in jeopardy. Making sure pathology services can cope with current and future demand is essential if we are to ensure early diagnosis and improve outcomes for patients.”
Lack/Loss of Trained Histopathologists an Ongoing Problem
In its most recent workforce report, The Royal College of Pathologists is reiterating its call for:
Increased funding for training;
Better information technology (IT) for day-to-day work;
Capital investment to implement digital pathology more widely; and,
Development of advanced clinical practitioner apprenticeships to help more biomedical scientists become independent practitioners who would work alongside medically-qualified histopathologists.
Long-term, the organization is calling for additional training slots for pathologists in universities as well as other changes to draw more scientists into the field.
Aging Pathology Staff Means Shortages in US a Possibility
The NHS has stopped short of declaring the pathologist shortage a crisis. Instead, a Department of Health and Social Care spokesperson in an interview with the BBC highlighted recent initiatives taken in response to the shortage. “There are hundreds more pathologists in the NHS compared to 2010 and hospitals have reduced spending on temporary agency staff by over half a billion pounds in the last year,” the spokesperson noted. “We are listening to staff, encouraging more flexible working, and have increased medical training places for home-grown doctors by 25%, to ensure the NHS has the workforce it needs for the future.”
Despite those steps, the NHS may have more work to do. According to the Royal College of Pathologists workplace survey, a quarter of all histopathologists in the UK are 55 or older, adding an approaching retirement crisis to the existing shortage.
US anatomic pathology groups and clinical laboratories should monitor these events with a keen eye. The American pathology industry is challenged by many of the same trends, such as an aging workforce and lackluster replacement initiatives. Time will tell if the US learns from the UK’s experience.
