CMS Releases Revision to State Operations Manual Special Procedures for Laboratories

Presenters at the 13th Annual Lab Quality Confab 2019 discussed the negative impact of disparities between medical laboratory processes and SOPs

ATLANTA, Oct. 18, 2019—Several weeks ago, the Centers for Medicare and Medicaid Services (CMS) quietly released QSO-19-20-CLIA: Revisions to State Operations Manual (SOM), Chapter 6—Special Procedures for Laboratories. The release, which went to all State Survey Agency Directors, includes a “comprehensive revision to establish quality laboratory policies and procedures to ensure accurate and reliable test results to protect patients and improve the quality of healthcare,” CMS’ website states.

The revisions went into effect September 26, 2019.

Clinical laboratory consultant Linda Flynn, Principal of LS Flynn and Associates, said “I find [the CMS release] very helpful because it can put you in the CMS inspector’s head—it offers a lot of insight.” Flynn highlighted QSO-19-20-CLIA during her breakout session, “Understanding the True Cost of Bad Quality, Both in Your Lab and Throughout Your Parent Hospital or Health Network,” at The Dark Report’s 13th Annual Lab Quality Confab (LQC) in Atlanta.

For clinical laboratory administrators, managers, and quality team members, reviewing the Special Procedures for Laboratories is worth the effort as part of your 2020 lab quality program and continuous improvement efforts. CMS made it easy to see what has changed by highlighting the revisions in red.

One revision worth noting is 6006.4–Certificate of Compliance, which has been revised to say, “A Certificate of Compliance is issued to a laboratory after an inspection finds the laboratory to be in compliance with all applicable requirements.”

CMS Stepping Up Scrutiny, Particularly in Preanalytical Phase

Laboratories that deviate practices and processes from their standard operating policies and procedures (SOPs) are going to get dinged, Flynn explained during her session. Some examples recommended for review included:

  • Validating specimen types, initially and as part of a change in a major component;
  • Showing that temperature is properly controlled during specimen transport; and
  • Mitigating risks as part of the shift to more nurse-drawn specimens.

Additionally, Flynn noted that addressing deficiency citations, deficiency practice related survey data tags (D-Tags), and Form CMS-2567 (Statement of Deficiencies and Plan of Correction) are all daunting and complex. Many D-Tags have multiple regulatory requirements, according to CMS.

During her breakout session at The Dark Report’s 13th Annual Lab Quality Confab in Atlanta, Linda Flynn (above), Principal of LS Flynn and Associates, explained that the rigors of a CMS inspection far exceed those of other inspectors. “This is digging,” she stressed, adding that a CMS inspection comes with a big team of career inspectors. “It’s almost punitive … they know what they are looking for.” (Photo copyright: The Dark Report.)

Are Medical Laboratories at Risk for Factors They Cannot Control?

Several attendees pointed out that in certain scenarios, specimen jeopardy and patient risk are out of the medical laboratory’s control. Nevertheless, Flynn says the laboratory is still responsible.

In addition to how a failure can adversely affect a patient, the cost of failures can run into the millions of dollars which are attributed to legal fees, consulting, staff overtime, and sanctions for the laboratory, she said.

To reduce risk, Flynn recommends that medical laboratory management address the complete lab continuum by getting out of the lab and interfacing with people outside the lab who may adversely affect specimens.

Lessons Learned Through Health System’s Policy Standardization Project

There are lessons to be learned from health systems that seek to standardize compliance and policies, explained Debra Zern, Director of Laboratory Quality and Internal Process Control at Intermountain Healthcare in Utah, during her LQC session, “Let’s Talk Process! Identifying and Communicating Best Practice Ideas Across Multiple Lab Sites to Standardize Compliance and Policies while Creating a Shared Culture.”

Intermountain generates approximately 10 million laboratory tests per month, according to Zern. However, years ago, the health system’s laboratories were not standardized at all. They were individually managed, they had been writing unique SOPs, they were purchasing their own equipment, and their vendor contracts were facility specific.

To standardize the labs, 11 discipline-specific practice councils (work groups) were developed, each including representatives from rural and core laboratory sites.

“What we found is that there is a lot of personal attachment to SOPs,” Zern said. “As a team, we came up with better wording than we did as individuals.” The end product was a single SOP, developed with the oversight of medical directors and workable for everyone.

Clinical laboratory administrators, managers, and quality team members learned much at this year’s LQC.

Federal Advisory Committee Seeks Public Comments on Revising CLIA Regulations, says Keynote Speaker at 13th Annual Lab Quality Confab in Atlanta

At The Dark Report’s annual Lab Quality Confab for clinical laboratory administrators, managers, and quality team members, experts outline how disruption in healthcare requires labs to improve processes and cut costs

ATLANTA, Oct. 15, 2019—Clinical laboratory professionals have a chance to advise the federal Centers for Disease Control and Prevention (CDC) on how the federal government could revise the regulations under the Clinical Laboratory Improvement Amendments of 1988 (CLIA). That’s according to one of the keynote speakers on Wednesday at The Dark Report’s 13th Annual Lab Quality Confab (LQC), which began here on Tuesday.

Reynolds M. Salerno, PhD, Director of the Division of Laboratory Systems (DLS) for the CDC in Atlanta, explained that the agency is collecting comments from the public and from its Clinical Laboratory Improvement Advisory Committee (CLIAC) on how to revise the CLIA regulations.

This is an opportunity for clinical laboratory directors, pathologists, and other lab professionals, to comment on the proposed revisions to CLIA before or during the upcoming CLIAC meeting on Nov. 6.

The agenda for the meeting is posted on the CDC’s website.

Public to be Heard on CLIA Regulations

“For the first time in its 26-year history, the council has called for three workgroups to address how to revise CLIA,” Salerno said. The workgroups will address these topics:

“It’s a dramatic step for the government to ask the laboratory community how to revise the CLIA regulations,” Salerno commented. Chartered in 1992, the advisory council meets twice a year, once in April and once in November.

CLIAC issued a summary report of its April 10-11 meeting. It also published an agenda for its upcoming meeting in Nov. 6.

In the coming weeks, Dark Daily will publish more information on how clinical laboratory professionals can comment on the important issue of CLIA revisions.

Digital slides from Salerno’s keynote address are posted on LQC’s presentations website.

Clinical Laboratory Testing is Increasing in Value, Keynote Speaker Says

As a service to clinical laboratories, Salerno outlined many of the services the CDC’s Division of Laboratory Systems provides for free to clinical labs, including information on such topics as:

During his remarks at the 13th Annual Lab Quality Confab in Atlanta, Salerno had good news for the clinical laboratory professionals in attendance. He said that lab testing was becoming a more valued commodity in healthcare because physicians and other providers were growing increasingly confident in lab test results.

Healthcare System Disruption Impacts Providers, Including Clinical Laboratories

Other keynote speakers addressed how disruption in the US healthcare systems affects provider organizations in significant ways. For clinical laboratories, such disruption has resulted in reduced payment and demands for quality improvement and shorter turnaround times.

For all these reasons, quality management systems may be every clinical laboratory’s best strategy to survive and thrive, the keynote speakers said.

The first keynoter was Robert L. Michel, Editor-in-Chief and Publisher of The Dark Report. Michel’s remarks focused on how price cuts from Medicare, Medicaid, private payers, and the drive for value-based payment, are requiring labs to do more with less. For this reason, quality management systems are necessary for all labs seeking to improve results, eliminate errors, and cut costs, he said.

“The people closest to the work know how to fix these problems,” he added. “That’s why labs know they must train their staff to identify problems and then report them up the chain so they can be fixed,” Michel commented. “Labs that are best at listening to their employees are getting very good at identifying problems by measuring results and monitoring and reporting on their own performance.”

Michel identified three principle factors that are disrupting healthcare:

  • The shift from reactive care in which the health system cares for sick patients to proactive care in which the health system aims to keep patients healthy and out of the hospital and other costly sites of care.
  • The transition away from fee-for-service payment that encourages providers to do more for patients, whether more care is needed or not, to value-based payment that aims to reward providers for keeping patients healthy.
  • The consolidation among hospitals, health systems, physicians, and other providers. A trend that requires clinical laboratories to find new partners and new ways to improve lab services and reduce costs.

Informatics Performance Data Help Clinical Laboratories Respond to Change

“The attributes of new and successful labs are that they will have faster workflow and shorter cycle times for clinical lab tests and anatomic pathology specimen results,” Michel explained. “That means that labs will attack non-value-added processes by implementing continuous improvement strategies [such as Lean and Six Sigma] and by the sophisticated use of informatics.”

Making use of performance data enables clinical laboratory directors to make changes in response to disruptions that affect healthcare. “If you have good informatics, then seven or eight of every 10 decisions you make will be good decisions, and with the other two and three decisions, you’ll have time to pull back and adjust,” Michel commented.

The second keynote speaker, Jeremy Schubert, MBA, MPH, Division Vice President of Abbott, reiterated what Michel said about how the health system is moving away from fee-for-service payment. Instead of focusing on caring for sick patients exclusively, he said, health insurers are paying all healthcare providers to keep patients healthy.

“Healthcare today is about the whole life course of the individual,” Schubert explained. “Patients no longer want healthcare only when they’re sick. Instead, they want to be healthy. And health creation is not just about a person’s physical health. It’s about their mental health, their emotional health, and their social wellbeing.

“In fact,” he continued, “you can learn more about a person’s health from their Zip code than from their genetic code.”

That is essentially what TriCore Reference Laboratories (TriCore) has been doing in New Mexico, Schubert added. During his presentation, Michel mentioned TriCore as being one of four clinical laboratories participating in Project Santa Fe, a non-profit organization that promotes the movement from Clinical Lab 1.0 to Clinical Lab 2.0. (See “TriCore Forges Ahead to Help Payers Manage Population Health,” The Dark Report, May 20, 2019.)

“If you want to be a quality engine in healthcare you have to be operating at Lab 2.0. Who is best qualified to interpret information? It’s the lab,” Schubert said. Then he challenged labs to begin pursuing the goal of achieving Lab 3.0, saying “Lab 3.0 is being able to interface with the patient to address each patient’s problems.”

The 13th Annual Lab Quality Confab (LQC) in Atlanta continues through the 17th with post-event workshops in Six Sigma and mastering quality management systems. In attendance are 300 clinical laboratory administrators, managers, and quality team members who are learning a complete array of professional training methods.

Canadian Diagnostics Executive Forum Will Provide Firsthand Insights into How Clinical Laboratories Can Leverage Technology and Innovation to ‘Do More with Less’

As demand rises, Canadian clinical laboratories must learn to juggle test systems automation, funding challenges, and staffing shortages

Canada’s clinical laboratories are deeply affected by many of the trends impacting the Canadian healthcare system overall. Deployment of new technologies, such as test automation and artificial intelligence (AI) for example, are forcing Canadian labs to adapt during times of changing demographics and funding pressures.

Thus, the Canadian Diagnostic Executive Forum (CDEF), which takes place October 24-25 at the Westin Harbour Castle Hotel in Toronto, will provide an opportunity for clinical laboratory leaders to learn how to leverage technology and create positive change in their medical laboratory operations.

Change Management and Clinical Laboratory Leaders

The development of disruptive new technologies is becoming the norm and the laboratory’s role in healthcare delivery is growing. That’s why change management has become a focus of clinical laboratory leaders.

Sheila Woodcock, Convenor, WG 1 Quality and Competence in the Medical Laboratory at ISO/TC 212, and President and Principal Consultant at QSE Consulting Inc., Nova Scotia, Canada, says “allocation of resources” is a challenge for senior diagnostic executives juggling financial, technology, and staffing decisions.

In an exclusive interview with Dark Daily, Woodcock said, “The number one lab challenge today is not having enough money; second is not having enough people. Because if you don’t have enough money, even if there are people out there, you can’t hire them. Money, people, and trying to keep up with all the technological innovations bombarding us nowadays are the main reasons to make changes.”

From deployment of digital pathology services and point-of-care (POC) testing to the introduction of automation and AI, innovation is happening at a rapid pace. It may or may not increase medical laboratory efficiency or support precision medicine, but it definitely alters laboratory infrastructure.

“Change is nearly constant in the clinical laboratory and the healthcare network worlds, and there are many complexities that go with that,” Woodcock said. “With the implementation of new technologies, and the rapidly advancing world of automation in clinical laboratories that have never before been automated, how do we ensure that when we automate new technology it doesn’t negatively impact the quality of the testing process?”

Disruptive Changes are Redefining Clinical Laboratories

As Clinical Lab Products (CLP) points out, medical laboratories have become a reservoir of data that can “guide fact-based decisions to improve operational, financial, and clinical performance throughout their institutions.” As a result, clinical laboratories are increasingly shedding their “traditional and narrowly defined roles” in which “physicians order tests and labs report results.”

Emerging technologies also are ushering change outside of the medical laboratory. Drones soon may routinely transport patient specimens across healthcare networks. Dark Daily has reported on several new drone transport systems under development around the globe. One such system in the US involves UPS, the FAA, and WakeMed. Such high-tech specimen tracking and delivery systems could lead to fewer spoiled samples and possibly save lives, and clinical laboratories are at the heart of these innovations.

Kevin D. Orr (above), Senior Director, Hospital Business at In-Common Laboratories, told Dark Daily that laboratory leaders need to keep up with technology breakthroughs. However, knowing which tools and strategies are worth implementing is not so easy. Orr says diagnostic executives should take advantage of opportunities to “network to understand what is going on in everybody’s backyard, and to leverage some of the strategies, tools, and technologies innovators have used elsewhere.” (Photo copyright: LinkedIn.)

Kevin D. Orr, Senior Director, Hospital Business at In-Common Laboratories, believes technology may help laboratories overcome one major issue—a growing demand for testing services at a time when the laboratory workforce is shrinking, and provincial and territorial global funding is not keeping pace with diagnostic utilization rates. Orr points to digital pathology as an example of a technology that may enable labs to “do more with less” in terms of both funding and staffing.

“As people get older, there’s more demand for healthcare services and because of that more clinical laboratory testing has to be done,” Orr told Dark Daily. “The peak of the Baby Boomers is starting to get sick now. We need to focus on innovations and technologies clinical laboratories are employing to address the overarching issue of doing more with less.”

How Clinical Laboratories Should Demonstrate Value

Woodcock, however, maintains that clinical laboratories also need to do a better job of lobbying for funding, so they have the money needed to implement new technologies.

“Traditionally, when labs are told they have cutbacks, they do their utmost to work within what they have been assigned. But other departments might be jumping up and down, getting more attention, and getting more funding,” she said. “One of the things lab people have to learn—and are getting better at as time goes on—is giving the lab a voice and making known the contributions the lab makes to diagnosis and treatment of patients in a facility.”

The Canadian Diagnostic Executive Forum on October 24-25 at the Westin Harbour Castle Hotel in Toronto provides such an opportunity for laboratory leaders to learn how to leverage technology to create positive change in lab operations.

“We want to inspire people,” Orr told Dark Daily. “We want people to leave this conference excited about what diagnostics is doing and where it’s headed and what other people are doing. We want to show them the bright light at the end of the tunnel, because sometimes when you’re dealing with the negative aspects of no money or no staff or no this or that, it gets pretty awful. We want to breathe some life and show them the rainbow and that the light at the end of the tunnel could be just around the corner.”

The CDEF conference will be hosted by In-Common Laboratories, in conjunction with The Dark Report, Dark Daily’s sister publication. This two-day event will be packed with thought-provoking sessions on digital pathology, next-generation technology, precision medicine, blockchain, sample tracking, and artificial intelligence, as well as updates from across Canada on the latest innovations and technologies being implemented in medical laboratories.

Canadian technology entrepreneur and philanthropist Jim Estill, CM OOnt, CEO Danby Appliances and ShipperBee, will be a featured speaker.

University of Edinburgh Study Finds Antimicrobial Bacteria in Hospital Wastewater in Research That Has Implications for Microbiologists

The highly infectious bacteria can survive treatment at local sewage plants and enter the food chain of surrounding populations, the study revealed

Researchers at the University of Edinburgh (UE) in Scotland found large amounts of antimicrobial-resistance (AMR) genes in hospital wastewater. These findings will be of interest to microbiologists and clinical laboratory managers, as the scientists used metagenomics to learn “how abundances of AMR genes in hospital wastewater are related to clinical activity.”

The UE study sheds light on the types of bacteria in wastewater that goes down hospital pipes to sewage treatment plants. The study also revealed that not all infectious agents are killed after passing through waste treatment plants. Some bacteria with antimicrobial (or antibiotic) resistance survive to enter local food sources. 

The scientists concluded that the amount of AMR genes found in hospital wastewater was linked to patients’ length-of-stays and consumption of antimicrobial resistant bacteria while in the hospital.

Using Metagenomics to Surveille Hospital Patients

Antimicrobial resistance is creating super bacteria that are linked to increases in hospital-acquired infections (HAIs) nationwide. Dark Daily has reported many times on the growing danger of deadly antimicrobial resistant “super bugs,” which also have been found in hospital ICUs (see “Potentially Fatal Fungus Invades Hospitals and Public Is Not Informed,” August 26, 2019.)

In a paper the University of Edinburgh published on medRxiv, the researchers wrote: “There was a higher abundance of antimicrobial-resistance genes in the hospital wastewater samples when compared to Seafield community sewage works … Sewage treatment does not completely eradicate antimicrobial-resistance genes and thus antimicrobial-resistance genes can enter the food chain through water and the use of [processed] sewage sludge in agriculture. As hospital wastewater contains inpatient bodily waste, we hypothesized that it could be used as a representation of inpatient community carriage of antimicrobial resistance and as such may be a useful surveillance tool.”

Additionally, they wrote, “Using metagenomics to identify the full range of AMR genes in hospital wastewater could represent a useful surveillance tool to monitor hospital AMR gene outflow and guide environmental policy on AMR.”

AMR bacteria also are being spread by human touch throughout city subways, bus terminals, and mass transportation, making it difficult for the Centers for Disease Control and Prevention (CDC) to identify the source of the outbreak and track and contain it. This has led microbiologists to conduct similar studies using genetic sequencing to identify ways to track pathogens through city infrastructures and transportation systems. (See, “Microbiologists at Weill Cornell Use Next-Generation Gene Sequencing to Map the Microbiome of New York City Subways,” December 13, 2013.)

Antimicrobial stewardship programs are becoming increasingly critical to preventing the spread of AMR bacteria. “By having those programs, [there are] documented cases of decreased antibiotic resistance within organisms causing these infections,” Paul Fey, PhD, of the University of Nebraska Medical Center, told MedPage Today. “This is another indicator of how all hospitals need to implement stewardship programs to have a good handle on decreasing antibiotic use.” [Photo copyright: University of Nebraska.]

Don’t Waste the Wastewater

Antibiotic resistance occurs when bacteria change in response to medications to prevent and treat bacterial infections, according to a World Health Organization (WHO) fact sheet. The CDC estimates that more than 23,000 people die annually from two million antibiotic-resistance infections.

Wastewater, the UE scientists suggest, should not go to waste. It could be leveraged to improve hospitals’ detection of patients with antimicrobial resistance, as well as to boost environment antimicrobial-resistance polices.

They used metagenomics (the study of genetic material relative to environmental samples) to compare the antimicrobial-resistance genes in hospital wastewater against wastewater from community sewage points. 

The UE researchers:

  • First collected samples over a 24-hour period from various areas in a tertiary hospital;
  • They then obtained community sewage samples from various locations around Seafield, Scotland;
  • Finally, they complete the genetic sequencing on an Illumina HiSeq4000 System.

The researchers reported these findings:

  • 181 clinical isolates were identified in the samples of wastewater;
  • 1,047 unique bacterial genes were detected across all samples;
  • 19 genes made up more than 60% of bacteria in samples;
  • Overriding bacteria identified as Pseudomonas and Acinetobacter environmental samples (Pseudomonas fluorescens and Acinetobacter johnsonii) were most likely from hospital pipes;
  • Gut-related bacteria—Faecalibacterium, Bacteroides, Bifidobacterium, and Escherichia, were more prevalent in the hospital samples than in those from the community;
  • Antimicrobial-resistance genes increased with longer length of patient stays, which “likely reflects transmission amongst hospital inpatients,” researchers noted. 

Fey suggests that further research into using sequencing technology to monitor patients is warranted.

“I think that monitoring each patient and sequencing their bowel flora is more likely where we’ll be able to see if there’s a significant carriage of antibiotic-resistant organisms,” Fey told MedPage Today. “In five years or so, sequencing could become so cheap that we could monitor every patient like that.”

Fey was not involved in the University of Edinburgh research.

Given the rate at which AMR bacteria spreads, finding antibiotic-resistance genes in hospital wastewater may not be all that surprising. Still, the University of Edinburgh study could lead to cost-effective ways to test the genes of bacteria, which then could enable researchers to explore different sources of infection and determine how bacteria move through the environment.

And, perhaps most important, the study suggests clinical laboratories have many opportunities to help eliminate infections and slow antibiotic resistance. Microbiologists can help move their organizations forward too, along with infection control colleagues.

Might Clinical Laboratories Soon be Processing Tests That Predict Whether Patients Will Die in 5-10 Years?

Metabolic panels of 14 blood-based biomarkers that can predict when a patient is likely to die may be coming to a medical laboratory near you

Clinical pathologists soon may be able to predict when patients will die, thanks to a recent study that reveals new insights into how the human body works. Researchers at the Max Planck Institute for Biology of Ageing in Germany and the Leiden University Medical Center (LUMC) in the Netherlands revealed a metabolic panel of biomarkers that can more accurately predict death within five to 10 years than standard measures.

The researchers’ original goal was to find blood-based biomarkers that could show whether a person was vulnerable to death, particularly if that vulnerability was related to modifiable lifestyle factors.

The researchers published their study, titled, “A Metabolic Profile of All-Cause Mortality Risk Identified in an Observational Study of 44,168 Individuals,” in the journal Nature Communications last August.

Metabolic Biomarkers More Accurate than Current Health Measures

During their investigation, the researchers looked at 12 cohorts from previous studies and examined the results of 44,168 individuals between the ages of 18 and 109. In the follow-up to the study, 5,512 of the participants died.

In the introduction to their published study the researchers wrote, “We first determine which metabolic biomarkers independently associate with prospective mortality in all individuals. Subsequently, we test the association of the biomarkers with mortality in different age strata.”

The researchers then used the 14 biomarkers they identified to create a score that predicts mortality within five to 10 years.

The measures that most providers currently use to determine an elderly person’s overall health generally include blood pressure, heart rate, and functionality measures such as grip strength and gait. However, P. Eline Slagboom, PhD, LUMC Professor of Molecular Epidemiology and the study’s director, told The Scientist that those metrics are not always accurate methods for measuring health.

“For example, a somewhat higher weight, blood pressure, or cholesterol level is not as bad for individuals over 80 years of age as compared to younger individuals,” she said.

As it turned out, the traditional measures were significantly less accurate than the score Slagboom and her team developed. Traditional measures were accurate about 78% of the time, while the metabolic panel was accurate about 83% of the time, reported The Scientist. Additionally, the score based on metabolic biomarkers was accurate for people of all ages, rather than only among the young.

“As researchers on aging, we are keen to determine the biological age. The calendar age just doesn’t say very much about the general state of health of elderly people: one 70-year old is healthy, while another may already be suffering from three diseases. We now have a set of biomarkers which may help to identify vulnerable elderly people,” said P. Eline Slagboom, PhD (above), LUMC Professor of Molecular Epidemiology and the study’s director, in a statement. (Photo copyright: Max Planck Institute for Biology of Ageing.)

Study Yields Strong but Surprising Results

Researchers have studied biomarkers as predictive tools for quite some time, with only narrow success. The positive results of the Max Planck Institute/LUMC study even surprised those who worked on it. “We were surprised that the association of our biomarker score with mortality was so strong, given that it is only based on 14 metabolic markers in the blood measured at a single point in the life of individuals,” the study’s lead author Joris Deelen, PhD, a postdoctoral researcher at the Max Planck Institute for Biology of Ageing, said in The Scientist.

But though the results of the study are intriguing, some experts remain skeptical that a new biomarker for death has been found.

In reactions published by the Science Media Centre, an independent organization in the UK that promotes “the reporting of evidence-based science,” Kevin McConway, PhD, Emeritus Professor of Applied Statistics at The Open University wrote, “This is a solid and interesting piece of research. But it doesn’t go beyond investigating the plausibility of setting up a system for predicting risk of death, based on this type of data. It doesn’t claim to do more than that, and makes clear that there’s some way to go, in terms of research and analysis, until a risk prediction tool that’s useable in clinical work with patients might emerge.”

And in the same article, Amanda Heslegrave, PhD, a post-doctoral research associate and researcher at the UK Dementia Research Institute at the University College London wrote, “Whilst this study shows that this type of profiling can be useful, [the researchers] do point out importantly that it would need further work to develop a score at the individual level that would be useful in real life situations. We’d need to see: validation to ensure repeatability in different labs, production of reference samples to test this on an ongoing basis, work to make the individual score possible, validation in other cohorts and validation of all components of the panel. So, it’s an exciting step, but it’s not ready yet.”

Past Mortality Biomarker Studies

Other investigations into the use of biomarkers as a predictive tool have focused more narrowly on specific causes of death. For example, in 2008, the New England Journal of Medicine (NEJM) published a study titled, “Use of Multiple Biomarkers to Improve the Prediction of Death from Cardiovascular Causes.” The study concluded that using biomarkers and risk factors together “substantially improves the risk stratification for death from cardiovascular causes.”

Another study, from 2017, examined stress biomarkers, hospital readmission, and death. Published in the Journal of Hospital Medicine titled, “Association of Stress Biomarkers with 30-Day Unplanned Readmission and Death,” the researchers found that “stress biomarkers improved the performance of prediction models and therefore could help better identify high-risk patients.”

Other studies have examined the predictive possibilities of biomarkers in:

Even with all of the research into biomarkers, scientists are still a long way from having a clinical tool to predict death. However, according to Leo Cheng, PhD, Associate Biophysicist, Pathology and Radiology at Massachusetts General Hospital, and Associate Professor of Radiology at Harvard Medical School, the Max Planck study is on the right path.

The Scientist states that though Cheng believes the study doesn’t “prove anything,” he also notes that “using a score that combines the information from all 14 biomarkers is ‘the correct thing [to do]’ to provide a holistic look at metabolic pathways that may represent a person’s health.”

So, it might be awhile before clinical laboratories will be processing metabolic panels that return test results predicting a patient’s mortality within 10-15 years. Nevertheless, how medical labs would be involved in such testing is certainly something to think about.
