Findings from the SafeCare study underscore importance of patient safety, need for continued improvement

Study led by Boston area hospitals demonstrates a need for better tools, increased measurement of patient harm and improved implementation systems


Peer-Reviewed Publication

MASS GENERAL BRIGHAM

More than 30 years ago, findings from the Harvard Medical Practice Study (HMPS) helped bring public awareness to the problem of patient safety. Since the publication of the HMPS results, new strategies for preventing specific types of adverse events have been put into place, but it has been challenging to measure the impact on patient care. To better understand what progress has been made in the last few decades, a team from Boston area hospitals conducted the SafeCare Study, which evaluated 11 hospitals in the region. Led by investigators from Mass General Brigham and sponsored by CRICO, the medical professional liability insurer for the Harvard medical community and its affiliated organizations, the study provides an estimate of adverse events in the inpatient environment, shedding light on the progress of two decades of work focused on improving patient safety and highlighting the need for continued improvement. Results are published in The New England Journal of Medicine.

“The study clearly demonstrates a need for better tools, increased measurement of patient harm, and better implementation systems,” said corresponding author David Westfall Bates, MD, medical director of Clinical and Quality Analysis for Mass General Brigham and chief of General Internal Medicine at Brigham and Women’s Hospital. “While we looked at hospitals in Massachusetts, improving the delivery of safe care is a national issue, not one that is specific to one hospital, system, state, or region. It’s valuable to know how much harm there is and for every institution to be aware of trends in adverse events so that they can take steps to mitigate and address issues within their walls.”

“Our work is a call to action for those from board to bedside to ensure reducing preventable patient harm is a top priority,” said Elizabeth Mort, MD, senior vice president of Quality and Safety at Massachusetts General Hospital and a co-author of the study. “Keep in mind that our study looked at patient safety before the COVID-19 pandemic. We know that our industry is now facing economic, workforce and wellness challenges nationally. Given these pressures, remaining focused and committed to patient safety is more important than ever.”

The SafeCare study followed a similar methodology to the HMPS, performed in 1984, although ways of capturing levels of harm have improved in the ensuing decades. Through review of 2,800 inpatient charts from patient visits in 2018 to hospitals ranging from large to small, the research team identified at least one adverse event in 23.6 percent of admissions. Overall, 23 percent of these adverse events were judged to be preventable given what is known today, and 32 percent had serious or higher clinical severity.

The leading causes of harm were medication related (39% of adverse events); surgery/procedural (30%); patient care, including falls and pressure ulcers (15%); and healthcare-associated infections (12%).

The rates of harm detected in the new study were higher than those from the HMPS, though different definitions were used. The authors note that the healthcare delivery system itself has changed dramatically since HMPS was conducted, with the advent of electronic health records and movement of complex care to ambulatory sites, leaving the most severely ill patients in our acute care hospitals. These changes present both challenges and opportunities.

“Because records are now computerized in nearly all hospitals, it should be possible to search them to make identification of these events much easier, which should in turn make it easier for hospitals to manage this area more effectively,” said Bates. “Based on our study, we are now taking steps to ensure that key findings do not get lost. We are also evaluating technological solutions that may help us better detect changes in respiratory rates, a patient’s pulse, and other early warning signs so that we can take steps to prevent or mitigate adverse events before they can cause harm.”

Bates and co-authors recommend that health care providers improve tracking of adverse drug effects, increase reliable and routine collection of data, deliver consistent and reliable care for healthcare-associated infections and work toward a culture that prioritizes safe, high-quality care.

“It’s important to do the work to identify adverse events if we’re going to work to improve them,” said Bates. “All organizations should have approaches for monitoring these things on a regular basis.”

Study reveals significant lack of infection-surveillance training in home infusion therapy setting


Results published in AJIC demonstrate need for HIT-specific training resources to improve infection prevention efforts in rapidly growing healthcare space


Peer-Reviewed Publication

ASSOCIATION FOR PROFESSIONALS IN INFECTION CONTROL

Arlington, Va., January 12, 2023 – A study published today in the American Journal of Infection Control (AJIC) reveals that many home infusion therapy (HIT) staff receive no formal training on how to perform central line-associated bloodstream infection (CLABSI) surveillance. The study, conducted by researchers from Johns Hopkins University, also identified specific training barriers that should be addressed to improve infection surveillance in this rapidly growing healthcare space.

“There was a 300% increase in patients receiving HIT in the United States between 2008 and 2019, and many of these individuals are at risk for CLABSI,” said Sara C. Keller MD, MSHP, MPH, Johns Hopkins University School of Medicine, and an author on the published study. “Appropriate, accurate CLABSI surveillance to understand rates in the HIT setting is necessary to drive prevention efforts.”

Infection prevention and surveillance training approaches have not been well defined in the HIT setting. Additionally, most HIT agencies do not employ dedicated, trained infection preventionists or devote sufficient resources to CLABSI surveillance activities, due in part to lack of funds and lack of mandated reporting of healthcare-associated infections (HAIs) in HIT.

HIT involves the administration of medicines through a catheter. CLABSIs are serious infections that can occur when bacteria enter the bloodstream through central line catheters. According to the CDC, of patients who get a bloodstream infection from having a central line, up to 1 in 4 may die.

Keller and colleagues conducted qualitative interviews with 21 home infusion staff from five large HIT agencies covering 13 states and Washington, DC. Questions posed to the staff – all of whom perform surveillance activities – focused on their surveillance training, barriers to and facilitators for CLABSI surveillance, and barriers to training in CLABSI surveillance.

Researchers found that many HIT staff who perform surveillance received no formal training on CLABSI surveillance. Study participants described instead a range of informal training experiences that included learning on the job (even from similarly untrained co-workers), relying on prior experience, and attending conferences. Participants also highlighted three primary barriers to HIT CLABSI surveillance training: Lack of learning resources such as user-friendly toolkits that accommodate high workload and time pressures; lack of awareness of professional development resources available to them; and lack of formal training provided by their respective organizations.

“These findings illustrate that there is a great need for infection prevention personnel and expertise in HIT,” said Patricia Jackson, RN, BSN, CIC, FAPIC, 2023 APIC president. “This information should prompt a concerted effort to implement formal infection prevention and surveillance training for HIT staff, including the development and deployment of training tools specific to the HIT setting.”

Taking on the triple threat of identifying the best organ donor, the earliest signs of transplant rejection and a better way to stop it

Taking on the triple threat of identifying the best organ donor, the earliest signs of transplant rejection and a better way to stop it

AUGUSTA, Ga.  –  Whether a humanized mouse model that shows great promise in identifying a patient’s best match for a living organ donor also holds promise for recognizing the earliest signs that the recipient’s immune system may start attacking that new organ is a question scientists want to answer.

“Current monitoring of patients picks up signs of damage to their transplanted kidney,” says Anatolij Horuzsko, MD, PhD, immunologist in the Georgia Cancer Center and Department of Medicine at the Medical College of Georgia at Augusta University. “That means the new kidney will no longer function optimally and may continue to decline. We’d like to intervene before that.”

Horuzsko is principal investigator on a new $1 million grant from the Carlos and Marguerite Mason Trust that will help identify the early presence of immune cells before they attack the new organ so the immunosuppressant medications the patient is taking can be modified to try and avert organ damage. The humanized mouse model he developed has the immune system of a specific transplant recipient, which can be exposed to blood of different potential living donors to see if it’s a good immunologic match and he has evidence it also can portend trouble ahead.

He also is looking further at a more natural, efficient and targeted way to deflect a destructive immune response with HLA-G, an immune molecule known to help the fetus, which has both father and mother’s DNA, escape attack by the mother’s immune system. Horuzsko, a leader in the field of HLA-G study, has shown that patients who have naturally higher levels of HLA-G have fewer problems with rejection and generally need fewer standard pharmaceuticals to help tamp down their immune response. Why some people have a higher level remains a mystery. But the scientists also are further refining a synthetic version, which is basically a double-dose of HLA-G, with the goal of one day giving it to patients as a more natural alternative to current immunosuppressive drugs.

Now he also is working to better define HLA-G’s relationship with B regulatory cells, which are known to suppress the immune response. There is clearly a connection because one of the receptors for B regulatory cells is ILT2 and HLA-G is the favored molecule to bind with ILT2. They want to better understand how that natural connection can translate to improved transplant success. And, whether monitoring the number and activity of B regulatory cells is a good way to predict success.

If it is, that could one day mean patients with naturally high activity of these cells likely would need less anti-rejection drug therapy, Horuzsko says. It also might point out who could benefit most from the synthetic HLA-G his lab is developing.

Back to the clues the humanized mouse model he developed may provide, Horuzsko notes that chronic kidney transplant rejection is slowly progressive and symptoms may not surface until late in the process. Current testing to monitor for rejection essentially show signs that it’s happening.

Today’s long list of approaches for detecting indicators of rejection include methods like looking at levels of creatinine, a waste product generated by using your muscles that normally is eliminated in the urine. High levels in the blood and/or low levels in the urine indicate that the kidney is not functioning optimally. Creatinine levels also are regularly measured in the blood of patients who still have their own kidneys as a measure of their health.

But Horuzsko notes that by the time creatinine levels, for example, are concerning, there is some degree of damage to the transplanted kidney. A biopsy of the kidney to look for damage remains another gold standard for detecting rejection, but the invasive test has its own complications that can damage the kidney.

Noninvasive, predictive donor-specific biomarkers are “highly desirable,” Horuzsko says. His study, published in the summer of 2021 in the journal Frontiers in Immunology showed that the humanized mouse model provided a more comprehensive prospective of how the patient’s immune system would react to a prospective living donor’s kidney that was more predictive than today’s standard. Dr. Laura Mulloy, chief of the MCG Division of Nephrology, and Horuzsko’s longtime clinical collaborator, calls the mouse model a more comprehensive, specific test.

Today, a handful of proteins on the surface of the donor’s and potential recipient’s cells are used to gauge how aggressively the recipient’s immune system will respond, in a process called human leukocytic antigen, or HLA, testing. A strong immune response indicates a strong possibility that the new organ will come under attack and that more drugs, which suppress the recipient’s immune system, will be needed. While continuously improved, today’s immunosuppressive drugs still leave patients more vulnerable for a variety of conditions the immune system typically helps control from viral infections to cancer.

As a way to see if this personalized approach also can improve immune  system surveillance, they will be creating additional humanized mouse models for recipients periodically after transplant and again challenging them with cells from the selected donor’s blood to see how the interaction may have changed. They will look at activation of key drivers of transplant rejection in the recipient, like CD8+ T cells, known to attack invaders with some nasty, destructive proteins like granzyme B and perforin, which kill off target cells. They will also monitor for the presence of biomarkers of these and other troublemakers as well as protective molecules like HLA-G, to analyze what constitutes a healthy or unhealthy mix for the new organ.

Horuzsko’s lab has already shown, for example, that HLA-G can inhibit activation of killer cells like CD8+ T cells.  Genomic analysis will help determine which genes are responsible for recruiting these killer cells to the transplanted kidney. Some 100 genes are already identified as players in transplant rejection but are not currently monitored in patients, he says. They are looking at those and all 27,000 human genes in the search for others.

“We are fighting to prolong kidney survival,” Horuzsko says. “We need to see the whole picture.”

He’s also further exploring the potential of the humanized mouse model he developed to better predict the best living organ donor.

The blood contains the components of the immune system. To build a humanized mouse model Horuzsko’s team worked for about five years to develop a method to isolate those components from a patient needing a transplant then reconstruct their immune system in a mouse that does not have one. Each potential living donor’s blood is then given to this engineered mouse to check how the recipient’s immune system should respond.

Now, they are increasing the number of patients for whom they are using the humanized mouse model to assess living donor candidates to ensure that the early success they have seen holds as time progresses for the 21 patients originally enrolled, as well as new ones. At this point, the new approach is used in addition to traditional HLA testing with the traditional test response still used to select a donor until studies of the new technique are complete.

Chronic rejection is the most common reason kidney transplants fail. Living donors result in the best success although more than half of transplants are with cadaver donors.

The Georgia-based Mason Trust works to improve the process of organ transplantation for needy Georgia residents. The trust distributes grants to 501(c)(3) organizations located in Georgia that can provide financial assistance to needy Georgia residents requiring transplants of eyes, kidneys, hearts, and other human organs. Up to 25% of the trust’s income also may be used for researching methods of improving the transplant of eyes, kidneys, hearts and other human organs.

University of Cincinnati research shows health benefits from Jewish tradition

Study shows expanded cardiovascular benefits wearing tefillin around the arm in both men and women

Peer-Reviewed Publication

UNIVERSITY OF CINCINNATI

Research from the University of Cincinnati shows people who wear tefillin, leather bands used in a Jewish religious practice which involves the tight wrapping of an arm with the bands, may receive cardiovascular health benefits. The study suggests those benefits are the result of ischemic or reduced blood flow preconditioning which produces protection from the damage caused by heart attacks.

The research was published in the journal PLOS ONE and expands on similar research by Rubinstein from 2018 that only enrolled men in the study. This study included both men and women.

“Tefillin is used for morning prayers for Jewish men over the age of 13 on an almost daily basis,” says Jack Rubinstein, MD, of the Division of Cardiovascular Health in the UC College of Medicine. “It is placed on the nondominant arm around the bicep and the forearm in a fairly tight manner. It is never worn in a fashion as to occlude the blood flow. This is traditionally worn for about 30 minutes continuously during prayers which involve sitting and standing resulting in occasional retightening of the strap around your arm.”

The use of tefillin dates back to scriptural commandments urging the faithful followers to comply with religious law and to “bind them as a sign upon your arm.” Rubinstein says the binding of the arm and the discomfort users often report may serve as a form of preconditioning and offer a substantial degree of protection against the damage that occurs when someone suffers a sudden loss of blood flow (acute ischemia) or after the blood supply is restored to a tissue or organ after an ischemic event (reperfusion). Such injuries occur during a heart attack when a section of the heart is deprived of oxygen and then damaged further when blood flow is reestablished.

Rubinstein says the researchers measured baseline information on all participants for 10 minutes in the morning, and then another round of data was obtained during and after 30 minutes of wearing the tefillin. The 30 participants, all healthy individuals between the ages of 18 to 40, had their heart rate measured before, during and after the wearing of tefillin.

“What we found is that wearing tefillin in both male and females caused changes to the heart rate associated with lowering of the metabolism as measured via heart rate variability,” says Rubinstein who explains that heart rate variability is how much variability there is between one heartbeat and the next heartbeat. “We can measure all kinds of different things from heart rate variability including probably the most important which is parasympathetic tone. Does it relax you and does it cause your metabolism [to] come down?”

The sympathetic and parasympathetic nervous systems have opposite roles. While the sympathetic nervous system carries signals that put the body's systems on alert, the parasympathetic carries signals that relax those systems. The two systems work together to keep the body in balance.

Rubinstein says this study shows there is a measurable effect during and after wearing tefillin.

“It means that if we can have people wearing tefillin or a similar device, and they can get themselves to be preconditioned every day, we expect that those people should be protected or should have a decreased amount of damage if they should get a heart attack during the time they are protected,” he explains. “This is a low-intensity way of protecting people from heart attacks.”

While wearing tefillin is a traditional practice of Orthodox Jewish men, Rubinstein points out this research did not include any usage of anything containing sacred religious text. He also says that the frequency of heart attacks, which according to the Centers for Disease Control and Protection strike more than 800,000 people in the United States each year, makes this research potentially very impactful.

“You have a very common and very deadly disease. We are showing a path through which anyone can precondition themselves to decrease the amount of damage that they suffer from a heart attack by wearing a very simple device,” says Rubinstein. “This is a potential game changer for how we approach cardiovascular disease prevention. Decreasing the amount of heart attack damage by even just two-fold is something that will change outcomes for millions of people.”

Harnessing the healing power within our cells


Peer-Reviewed Publication

UNIVERSITY OF QUEENSLAND

University of Queensland researchers have identified a pathway in cells that could be used to reprogram the body’s immune system to fight back against both chronic inflammatory and infectious diseases.

Dr Kaustav Das Gupta and Professor Matt Sweet from UQ’s Institute for Molecular Bioscience discovered that a molecule derived from glucose in immune cells can both stop bacteria growing and dampen inflammatory responses.

Dr Das Gupta said the finding is a critical step towards future therapeutics that train immune cells.

“The effects of this molecule called ribulose-5-phosphate on bacteria are striking – it can cooperate with other immune factors to stop disease-causing strains of the E. coli bacteria from growing,” Dr Das Gupta said.

“It also reprograms the immune system to switch off destructive inflammation, which contributes to both life-threatening infectious diseases such as sepsis as well as chronic inflammatory diseases like respiratory diseases, chronic liver disease, inflammatory bowel disease, rheumatoid arthritis, heart disease, stroke, diabetes and dementia.”

The research was carried out on a strain of E. coli bacteria that causes approximately 80 per cent of urinary tract infections and is a common cause of sepsis.

Pre-clinical trials were used to confirm the role of this pathway in controlling bacterial infections.

Professor Sweet said human cells were also used to demonstrate that ribulose-5-phosphate reduces the production of molecules that drive chronic inflammatory diseases.

“Host-directed therapies which train our immune systems to fight infections, will become increasingly important as more types of bacteria become resistant to known antibiotics,” Professor Sweet said.

“A bonus is that this strategy also switches off destructive inflammation, which gives it the potential to combat chronic disease.

“By boosting the immune pathway that generates ribulose-5-phosphate, we may be able to give the body the power to fight back against inflammatory and infectious diseases – not one, but two of the major global challenges for human health.”

Many current anti-inflammatory therapies target proteins on the outside of cells but because this pathway occurs inside cells, the researchers devised a new approach to target the pathway using mRNA technology.

Professor Sweet said the technology has shown promising results to deliver the enzyme that generates ribulose-5-phosphate into immune cells and has been filed as a provisional patent by UniQuest, UQ’s commercialisation company.

The work involved international and national cooperation, including UQ researchers Professor David Fairlie and Professor Mark Schembri as key collaborators.

The research was published in the journal, Proceedings of the National Academy of Sciences (PNAS).

Can boiled peanuts help cure peanut allergies?

Peer-Reviewed Publication

WILEY

Because heat can affect the structure and immunoreactivity of peanuts, researchers recently tested whether a therapy using sequential doses of boiled peanuts followed by roasted peanuts may help children overcome peanut allergies. Their open label, phase 2, single arm clinical trial, which is published in Clinical & Experimental Allergy, generated promising results.

For the trial, 70 children aged 6–18 years old with peanut allergies received 12-hour boiled peanuts for 12 weeks, 2-hour boiled peanuts for 20 weeks, and roasted peanuts for 20 weeks, to a target maintenance dose of 12 roasted peanuts daily.

Fifty-six of the 70 (80%) participants became desensitized to peanuts. Treatment-related adverse events were reported in 43 (61%) participants, 3 of whom withdrew from the trial.

“Oral immunotherapy using boiled followed by roasted peanuts represents a pragmatic approach that appears effective in inducing desensitization and is associated with a favourable safety profile,” the authors wrote.

Can algae enhance skin regeneration and wound healing?

Peer-Reviewed Publication

WILEY

A product of a freshwater single-celled green algae called Euglena gracilis may enhance skin regeneration to speed up wound healing, according to new research published in Advanced Materials Interfaces.

Investigators developed a system based on microvesicles that bud from the cell surface of Euglena gracilis and contain β-glucan, a carbohydrate with immunoregulatory activity, regeneration ability, and antioxidant properties.

In laboratory experiments, these microvesicles promoted the proliferation and migration of skin cells, increasing both collagen synthesis and the expression of proliferation-associated proteins. A wound healing test also generated promising results. 

“This technique is expected to be applied to other cells, thereby enabling the design of new types of extracellular vesicles that are applicable for skin treatments and care in the pharmaceutical and cosmetic industries,” the authors wrote.

UNF study finds dual COVID and flu vaccination reduces infection rates

Peer-Reviewed Publication

UNIVERSITY OF NORTH FLORIDA

Jacksonville, Fla. – University of North Florida Brooks College of Health faculty recently published a study showing dual COVID-19 and seasonal influenza vaccinations are associated with reduced infection rates and can be an effective strategy to reduce the contagious respiratory disease burden during the winter.

The study found individuals with dual vaccination and COVID-19 vaccine only were significantly less likely to report COVID-19 infection when compared with those unvaccinated. There was no significant difference in self-reported COVID-19 symptom severity by vaccination status.

Dr. Zhigang Xie, public health assistant professor, and Dr. Hanadi Hamadi, health administration associate professor, partnered with two University of Florida researchers for the study. Using data from the 2021 National Health Interview Survey, the team conducted descriptive analysis and multivariate logistic regressions to examine the association between dual vaccination status and self-reported COVID-19 infection and severity among 21,387 (weighted 185,251,310) U.S. adults. Of those in the survey, about 22% did not receive either the flu or COVID-19 vaccine, 6.0% received the flu vaccine only, 29.1% received the COVID-19 vaccine only, and 42.5% received both vaccines.
