With public trust in healthcare organizations dropping, clinical laboratories worldwide must work doubly hard to provide competent, secure services to their patients
Is the UK’s National Health Service hurting people? About 10% of NHS patients said yes in a recent survey conducted by the London School of Hygiene and Tropical Medicine (LSHTM) and the University of Oxford. And those findings are a public stain on the physicians and clinical laboratories in an already strained healthcare system.
Of the 10,000 people interviewed, nearly 1,000 “reported they had experienced harm caused by the NHS in the previous three years. Of those, 6.2% cited their treatment or care and 3.5% blamed the harm on a lack of access to NHS services,” according to an LSHTM news release.
While the definition of “hurt” within the confines of the survey wasn’t specified, what is clear is that public trust in the UK’s healthcare system is decreasing. Fallout from the survey may affect the public’s trust in clinical labs that are facing unfavorable feedback from slow test result delivery times or rare instances of incorrect results.
“I’ve been studying patient safety and working in and with the NHS, including as a GP, for many years. It’s a complex challenge to pinpoint the cause of the problem and solve it,” said study author Helen Hogan, PhD, MBBS, a general practitioner and associate professor in the department of Health Services Research and Policy at LSHTM, in the news release.
“These findings indicate that healthcare harm affects a considerable number of the general public. It shows that there is still some way to go to improve safety across the NHS,” said study author Helen Hogan, PhD, MBBS, general practitioner and associate professor in the department of Health Services Research and Policy at LSHTM, in a news release.

Of the 9.7% that reported NHS harm, 6.2% claimed it was from the actual treatment or care given and 3.5% from the access to care. Severity ranged from 37.6% reporting moderate impact to 44.8% reporting severe impact, and the majority claimed the impact occurred at hospitals, the authors wrote in BMJ Quality and Safety.
Women led the respondents in reports of harm, and more severe harm or higher rates of harm were reported from those in disadvantaged groups or lower social grades and those with disabilities or long-term illness, according to the researchers.
Though 60% got professional support for their troubles, including 11.6% contacting the NHS’ Patient Advice and Liaison Service (PALS), only 17% made a formal complaint. A small percentage, 2.5%, sought financial compensation, the survey showed.
Poor Patient Service Experience
Further, the patients reported poor results when they sought relief from the harm. Some (44.4%) desired treatment or care to help with the harm, while others (34.8%) wanted an explanation for the harm. Two-thirds said their incidents were not dealt with well and only half reported a positive PALS experience, the survey noted.
“Those harmed by healthcare are looking for a compassionate and caring response from services. What they really want is to be listened to, to have their harm acknowledged, and get an explanation,” noted Michele Peters, PhD, fellow survey author and associate professor at Oxford Population Health, University of Oxford, in the LSHTM news release.
Loss in Confidence
To make matters worse for the UK’s publicly run healthcare system, an unrelated patient satisfaction survey published contemporaneously found that NHS satisfaction hit record lows. According to The Guardian, the annual patient survey found a 24% decrease in satisfaction among adults in Britain in how NHS is run (now at a mere 21%). Dissatisfaction rose from 52% to 59% in the past year.
General practice, accident and emergency, and dental care were the areas of biggest disappointment, the study revealed.
“It is by far the most dramatic loss of confidence in how the NHS runs that we have seen in 40 years of this survey,” said Mark Dayan, a policy analyst at the Nuffield Trust who was engaged by The King’s Fund to analyze the survey data.
“There is a need to better understand the patient perspective following harm and for further consideration of what a person-centered approach to resolution and recovery might look like,” the researchers noted in BMJ Quality and Safety.
These types of findings can contribute to public mistrust of healthcare organizations worldwide, including clinical laboratories and pathology groups. It’s worth watching how the NHS resolves these issues.
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.
