Do plastic chemicals contribute to the sudden death of patients on dialysis?

Nikki Gillum Posnack

Nikki Posnack, Ph.D., assistant professor with the Children’s National Heart Institute, continues to explore how repeat chemical exposure from medical devices influences cardiovascular function.

In a review published in HeartRhythm, Larisa Tereshchenko, M.D., Ph.D., FHRS, a researcher with the Knight Cardiovascular Institute at Oregon Health and Science University, and  Nikki Posnack, Ph.D., an assistant professor at the Children’s National Heart Institute, establish a strong foundation for a running hypothesis: Replacing BPA- and DEHP- leaching plastics for alternative materials used to create medical devices may help patients on dialysis, and others with impaired immune function, live longer.

While Drs. Tereshchenko and Posnack note clinical studies and randomized controlled trials are needed to test this theory, they gather a compelling argument by examining the impact exposure to chemicals from plastics used in dialysis have on a patient’s short- and long-term health outcomes, including sudden cardiac death (SCD).

“As our society modifies our exposure to plastics to mitigate health risks, we should think about overexposure to plastics in a medical setting,” says Posnack. “The purpose of the review in HeartRhythm is to gather data about the impact chemical compounds, leached from plastic devices, have on cardiovascular outcomes for patients spending prolonged periods of time in the hospital.”

In this review, the authors explore chemical risk exposures in a medical setting, starting with factors that influence sudden cardiac death (SCD) among dialysis patients.

Why study dialysis patients?

SCD in dialysis patients accounts for one-third of deaths in this population. This prompts a need to develop prevention strategies, especially among patients with end-stage renal disease (ESRD).

The highest mortality rate observed among dialysis patients is during the first year of hemodialysis, a dialysis process that requires a machine to take the place of the kidneys and remove waste from the bloodstream and replenish it with minerals, such as potassium, sodium and calcium. During this year, mortality during hemodialysis is observed more frequently during the first three months of treatment, especially among older patients.

Possible reasons for an increased risk of an earlier death include chemical exposure, which is casually associated with altered cardiac function, as well as genetic risks for irregular heart rhythms and heart failure. In the HeartRhythm review, Drs. Tereshchenko and Posnack analyze factors that influence mortality:

Hemodialysis treatment, dialysis, is associated with plastic chemical exposure

Drs. Tereshchenko and Posnack note that dialysis tubing and catheters are commonly manufactured using polyvinyl chloride (PVC) polymers. The phthalate plastics used to soften PVC can easily leech if exposed to lipid-like substances, like blood. Research shows phthalate chemical concentrations increase during a four-hour dialysis.

Di(2-ethylhexyl) phthalate (DEHP) is a common plastic used to manufacture dialysis tubes, thanks to its structure and economy.

Bisphenol-A (BPA) is another common material used in medical device manufacturing. From the membranes of medical tools to resins, or external coatings and adhesives, BPA leaves behind a chemical residue on PVC medical devices.

In reviewing the research, the authors find dialysis patients are often exposed to high levels of DEHP and BPA. The amount of exposure to these chemicals varies in regards to room temperature, time of contact, other circuit coatings and the flow rate of dialysis. A faster flow rate correlates with reductions in chemical leaching and lower mortality rates.

Plastic chemical exposure is casually associated with altered cardiac function

Drs. Tereshchenko and Posnack note a causal relationship already exists between chemicals absorbed from plastics and cardiovascular outcomes.

Dr. Posnack’s previous research found BPA concentrations impaired electrical conduction in neonatal cardiomyocytes – young, developing heart cells – potentially altering the heart’s normal rhythm and function.

To the best of their knowledge, no clinical research has been conducted on DEHP exposure and SCD. However, proof-of-concept models find in vivo phthalate exposure alters autonomic regulation, which can slow down natural heart-rate rhythm and create a lag in recovery time to stressful stimuli. For humans, this type of stressful stimulation would be equivalent to recovering from a bike ride, car accident, or in this case, ongoing dialysis treatment with impaired immune function.

In other models, BPA exposure has been shown to cause bradycardia, or a delayed heart rate. In excised whole heart models, BPA has also been shown to alter cardiac electrical activity.

Abnormal electrophysiological substrate in end-stage renal disease

Since the heart and kidneys work in tandem to transport blood throughout the body, and manage vital functions, such as our heart rate, blood flow and breathing, the authors cite additional factors that lead to ongoing heart and kidney problems, with a look at end-stage renal disease (ESRD).

General heart-function kidney risks include abnormal electrophysiological (EP) substrate, the underlying electrical activity of the cardiac tissue, and genetic risk factors, including the TBX3 gene, a gene associated with a unique positioning of the heart and SCD.

“We don’t want to cite alarm about having a medical procedure or about relying on external help, such as dialysis, for proper kidney function,” says Posnack. “Especially since dialysis is a life-saving medical intervention for patients with inadequate kidney function.”

Pre-existing abnormal EP substrate interacts with plastic chemical exposure in incident dialysis, which increases risk of SCD in genetically predisposed ESRD patients

To summarize their findings, Drs. Tereshchenko and Posnack list a handful of support areas, starting with observations about reductions in cardiovascular mortality and SCD following kidney transplants. They note hemodialysis catheters are associated with larger DEHP exposure and a higher risk of SCD, compared to arteriovenous fistulas, highways surgically created to connect blood from the artery to the vein.

Drs. Posnack and Tereshchenko also note a correlative observation about higher SCD rates observed six hours after hemodialysis, when peak levels of DEHP and BPA are circulating in the bloodstream.

To compare and control for these factors among dialysis patients, the researchers cite different mortality patterns with hemodialysis and peritoneal dialysis. Patients on hemodialysis experience higher mortality during the first year of treatment, compared to peritoneal dialysis, who have higher mortality rates after the second year of treatment. Hemodialysis relies on a machine to take the place of kidney function, while peritoneal dialysis relies on a catheter, a small tube surgically inserted into the stomach.

“Our goal is to build on our previous research findings by analyzing variables that have yet to be studied before, and to update the field of medicine in the process,” says Dr. Posnack. “This includes investigating the cardiovascular risks of using BPA- and DEHP-materials to construct medical devices. Ultimately, we hope to determine whether plastic materials contribute to cardiovascular risks, and investigate whether patients might benefit from the use of alternative materials for medical devices.

Drs. Tereshchenko and Posnack note that despite the associations between chemical exposure from medical devices and increased cardiovascular risks, there are no restrictions in the United States on the use of phthalates and BPA chemicals used to manufacture medical devices.

Their future research will explore how replacing BPA- and DEHP-leaching plastics influence mortality and morbidity rates of ESRD patients on dialysis, as well as other patients exposed to repeat chemical exposure, such as patients having cardiac surgery.

“We want to make sure we identify and then work to minimize any potential risks of plastic exposure in a medical setting,” adds Dr. Posnack. “Our goal is to put the health and safety of patients first.”

Dr. Posnack’s research is funded by two grants (R01HL139472, R00ES023477) from the National Institutes of Health.

Making weight: Ensuring that micro preemies gain pounds and inches

Tory Peitz and Victoria Catalano

Tory Peitz, R.N., (left) and Victoria Catalano, RDN, LD, CNSC, CLC, (right) Pediatric Dietitian Specialist in the Neonatal Intensive Care Unit at Children’s National Health System, measure the length of a micro preemie who weighed 1.5 pounds at birth.

A quality-improvement project to standardize feeding practices for micro preemies – preterm infants born months before their due date –  helped to boost their weight and nearly quadrupled the frequency of lactation consultations ordered in the neonatal intensive care unit (NICU), a multidisciplinary team from Children’s National Health System finds.

According to the Centers for Disease Control and Prevention, about 1 in 10 infants in 2016 was preterm, born prior to completing 37 gestational weeks of pregnancy. Micro preemies are the tiniest infants in that group, weighing less than 1,500 grams and born well before their brain, lungs and organs like the liver are fully developed.

As staff reviewed charts for very low birth weight preterm infants admitted to Children’s NICU, they found dramatic variation in nutritional practices among clinicians and a mean decline in delta weight Z-scores, a more sensitive way to monitor infants’ weight gain along growth percentiles for their gestational age. A multidisciplinary team that included dietitians, nurses, neonatologists, a lactation consultant and a quality-improvement leader evaluated nutrition practices and determined key drivers for improving nutrition status.

“We tested a variety of strategies, including standardizing feeding practices; maximizing intended delivery of feeds; tracking adequacy of calorie, protein and micronutrient intake; and maximizing use of the mother’s own breast milk,” says Michelande Ridoré, MS, a Children’s NICU quality-improvement lead who will present the group’s findings during the Virginia Neonatal Nutrition Association conference this fall. “We took nothing for granted: We reeducated everyone in the NICU about the importance of the standardized feeding protocol. We shared information about whether infants were attaining growth targets during daily rounds. And we used an infographic to help nursing moms increase the available supply of breastmilk,” Ridoré says.

On top of other challenges, very low birth weight preterm infants are born very lean, with minimal muscle. During the third trimester, pregnant women pass on a host of essential nutrients and proteins to help satisfy the needs of the fetus’ developing muscles, bones and brain. “Because preterm infants miss out on that period in utero, we add fortification to provide preemies with extra protein, phosphorus, calcium and zinc they otherwise would have received from mom in the womb,” says Victoria Catalano, RDN, LD, CNSC, CLC, a pediatric clinical dietitian in Children’s NICU and study co-author. Babies’ linear growth is closely related to neurocognitive development, Catalano says. A dedicated R.N.  is assigned to length boards for Children’s highest-risk newborns to ensure consistency in measurements.

Infants who were admitted within the first seven days of life and weighed less than 1,500 grams were included in the study. At the beginning of the quality-improvement project, the infants’ mean delta Z-score for weight was -1.8. By December 2018, that had improved to -1.3. And the number of lactation consultation ordered weekly increased from 1.1 to four.

“We saw marked improvement in micro preemies’ nutritional status as we reduced the degree of variation in nutrition practices,” says Mary Revenis, M.D., NICU medical lead on nutrition and senior author for the research. “Our goal was to increase mean delta Z-scores even more. To that end, we will continue to test other key drivers for improved weight gain, including zinc supplementation, updating infants’ growth trajectories in the electronic medical record and advocating for expanded use of birth mothers’ breast milk,” Dr. Revenis says.

In addition to Ridoré, Catalano and Dr. Revenis, study co-authors include Caitlin Forsythe MS, BSN, RNC-NIC, lead author; Rebecca Vander Veer RD, LD, CNSC, CLC, pediatric dietitian specialist; Erin Fauer RDN, LD, CNSC, CLC, pediatric dietitian specialist; Judith Campbell, RN, IBCLC, NICU lactation consultant; Eresha Bluth MHA; Anna Penn M.D., Ph.D., neonatalogist; and Lamia Soghier M.D., Med., NICU medical unit director.

Washington Adult Congenital Heart Program staff

The Washington Adult Congenital Heart Program earns national accreditation from the Adult Congenital Heart Association

Washington Adult Congenital Heart Program staff

The Washington Adult Congenital Heart Program (WACH), part of Children’s National, earns accreditation from the Adult Congenital Heart Association for providing high-level, integrated care to patients with congenital heart disease.

Anitha John, M.D., Ph.D., a congenital heart disease (CHD) specialist and the director of the Washington Adult Congenital Heart Program (WACH) at Children’s National Health System, is a master of creating and leading multidisciplinary teams and networks to drive innovative standards to accelerate personalized treatment for adults born with heart conditions.

The Adult Congenital Heart Association (ACHA), a national organization dedicated to advancing adult congenital heart disease (ACHD) care, announces WACH as one of 19 medical centers in the country – and the first in the Mid-Atlantic region – to earn its accreditation, which signifies a center that provides high-level, comprehensive care.

WACH receives this accreditation by meeting ACHA’s criteria, which includes medical services and personnel requirements, and going through a rigorous accreditation process, both of which were developed over a number of years through a collaboration with doctors, physician assistants, nurse practitioners, nurses and ACHD patients.

There are 1.4 million adults in the U.S. living with one of many different types of congenital heart defects, ranging among simple, moderate and complex.

“There are now more adults than children in the U.S. with CHD,” said Mark Roeder, President and CEO of ACHA. “Accreditation will elevate the standard of care and have a positive impact on the futures of those living with this disease. Coordination of care is key, and this accreditation program will make care more streamlined for ACHD patients, improving their quality of life.”

A study published in Circulation examined mortality rates among 70,000 patients living with CHD over a 15-year period, from 1990 to 2005, and saw mortality rates fall with referrals to specialized ACHD care centers.

“This accreditation lets patients and other specialists know what to expect if they visit our center,” says Dr. John. “While the field of congenital heart disease is small enough to personalize, it’s large enough to standardize. I’m grateful to work with a wonderful team to provide this type of high-level care.”

Dr. John has a unique background to elevate standards of ACHD care, while creating tailored prescriptions. She is one of a handful of physicians with subspecialty training in ACHD, which she completed at the Mayo Clinic. Her formal training in internal medicine and general pediatrics, completed at Brown University, fits well with the subspecialty training she received as a pediatric cardiology fellow at Children’s Hospital of Philadelphia. Her research now focuses on clinical outcomes in congenital cardiology and advancing multicenter research efforts in adult congenital cardiology.

From March 2016 to 2018, Dr. John led the Alliance for Adult Research in Congenital Cardiology, the major multicenter research group in the U.S. focused on ACHD research. She’s also working with experts and patient advocates to guide efforts to set up a future ACHD patient registry, which will continue to guide research efforts and educate providers about ACHD care.

To help facilitate collaboration, Dr. John guides quarterly meetings of the Mid-Atlantic ACHD regional group.  Established in 2011 through Children’s National, the group has expanded to include ACHD providers from over 18 programs/practices from across the East Coast. This group provides a forum for patient case discussion and programmatic support. More importantly, the professional collaboration has served to not only improve patient care but also provides support to providers as they continue to care for a growing population of patients. This type of collaboration fosters mutual understanding and sets the stage for a relaxed but collegial environment where questions flow and learning occurs.

To further facilitate education, she created an inaugural patient day at the 7th Annual Adult Congenital Heart Disease in the 21st Century conference this past year, allowing patients to have their own educational summit – while opening the opportunity to providers to stay an extra day to learn about patient-centered care. The conference relies heavily on the participation of the Mid-Atlantic ACHD regional group of providers.

Patients learned as much about 3D heart models, pacemakers and noninvasive surgical techniques as they did about personalized approaches to lifestyle care, from practicing mindfulness to hearing about communication strategies to use with their medical teams and families. A variety of experts, from cardiac surgeons to clinical social workers, led the panels and breakout sessions.

“We’re empowering patients to become an active participant and an engaged member of their medical care team,” adds Dr. John.

ACHA supports WACH’s efforts and spoke at the conference, complementing its mission to serve and support the more than one million adults with CHD, their families and the medical community.

The WACH team includes not only Dr. John, but ACHD cardiologists Seiji Ito, M.D., and Tacy Downing, M.D.; Pranava Sinha, M.D., surgical director; Rachel Steury, R.N.P., advanced practitioner; Nancy Klein, R.N., clinical coordinator; Emily Stein, M.S.W., social worker; Whitney Osborne, M.P.H., clinical research coordinator, and Ruth Phillippi, M.S., program coordinator. The team works together seamlessly to fulfill the program mission of achieving clinical excellence, promoting research and providing education in the care of adults of with CHD.

Graph showing magnesium reduces arrhythmia risk

Magnesium helps prevent postsurgical arrhythmias in pediatric patients

Graph showing magnesium reduces arrhythmia risk

Magnesium (Mg) helps reduce arrhythmias, irregular heart rhythms, in adults. It also helps alleviate the symptoms of postoperative atrial fibrillation, or AFib, which can lead to blood clots, stroke and heart failure. Can it help prevent postsurgical arrhythmias in pediatric patients with congenital heart disease?

New research from Children’s National Health System finds a 25- or 50-mg dose of Mg used during congenital heart surgery (CHS) helps prevent arrhythmias, especially junctional ectopic tachycardia (JET) and atrial tachycardia (AT), common arrhythmias following CHS, according to a study published in the August 2018 edition of The Journal of Thoracic and Cardiovascular Surgery.

To reach this conclusion, the researchers separated 1,871 CHS patients from Children’s National into three groups: a control group of 750 patients who had surgery without Mg, a group of 338 patients receiving a 25-mg /kg dose of Mg during surgery and a group of 783 patients receiving a 50-mg/kg dose of Mg during surgery. The data looked at CHS cases over eight years, from 2005 to 2013, to determine if Mg administration during surgery alleviates postoperative arrhythmias and if the amount, measured by a 25- or 50-mg/kg dose, makes a difference.

“This study, the first conducted in pediatric patients, finds administering magnesium during congenital heart surgery reduces the likelihood of postsurgical arrhythmias,” says Charles Berul, M.D., a study author and the chief of cardiology at Children’s National. “We don’t detect a dose-dependent relationship, which means a small or larger amount of magnesium is equally effective at preventing arrhythmias following surgery.”

The researchers found that up to one-third of CHS patients experience postoperative arrhythmias, with JET and AT accounting for more than two-thirds of arrhythmias following CHS. They note that despite the administration of Mg during surgery, there continues to be a high incidence of postoperative arrhythmias – affecting 18 percent or about one in five CHS patients.

“We hope this study guides future research to see if adding new or additional agents to magnesium eliminates, or further reduces, postoperative arrhythmias,” notes Dr. Berul. “For now, we’re happy to find an algorithm to put into practice and to share with other medical centers, as a way to help pediatric patients recover from congenital heart surgery—stronger, faster and with a reduced risk of complications.”

The researchers note that postoperative arrhythmias impact the recovery period of CHS, increase the duration of intubation and CICU stay and prolong hospital stay.

Missed opportunities for STI screening in the ED

Monika Goyal

Children’s researchers led by Monika K. Goyal, M.D., M.S.C.E., find that even though young women with pelvic inflammatory disease (PID) are at increased risk for being infected with syphilis and human immunodeficiency virus (HIV), few adolescent females diagnosed with PID in U.S. pediatric emergency departments undergo laboratory tests for HIV or syphilis.

Sexually transmitted infections (STIs) are on the rise in the U.S., reaching unprecedented highs in recent years for the three most common STIs reported in the nation: chlamydia, gonorrhea and syphilis. Nearly half of the 20 million new STI cases each year are in adolescents aged 15 to 24, according to the Department of Health & Human Services. In particular, about two in five sexually active teen girls has an STI.

These infections can be far more than an embarrassing nuisance; some can cause lifelong infertility. According to the Centers for Disease Control and Prevention, undiagnosed STIs cause infertility in more than 20,000 women each year.

A new retrospective cohort study led by researchers at Children’s National Health System and published online July 24, 2018, in Pediatrics shines a stark spotlight on missed opportunities for diagnosis. Researchers found that even though young women with pelvic inflammatory disease (PID) are at increased risk for also being infected with syphilis and human immunodeficiency virus (HIV), few adolescent females diagnosed with PID in U.S. pediatric emergency departments (ED) undergo laboratory tests for HIV or syphilis.

A team of Children’s researchers reviewed de-identified data from the Pediatric Health Information System, a database that aggregates encounter-level data from 48 children’s hospitals across the nation. From 2010 through 2015, there were 10,698 diagnosed cases of PID among young women aged 12 to 21. Although HIV and syphilis screening rates increased over the study period, just 27.7 percent of these women underwent syphilis screening, 22 percent were screened for HIV, and only 18.4 percent underwent lab testing for both HIV and syphilis.

Screening rates varied dramatically by hospital, with some facilities screening just 2 percent of high-risk young women while others tested more than 60 percent.

HIV screening was more likely to occur among:

  • Women admitted to the hospital, compared with those discharged from the ED (adjusted odds ratio [aOR] of 7.0)
  • Uninsured women, compared with women with private insurance (1.6 aOR)
  • Non-Latino African American women, compared with non-Latino white women (1.4 aOR)
  • Women seen at small hospitals with fewer than 300 beds (1.4 aOR)
  • Women with public insurance compared with women with private insurance (1.3 aOR)
  • 12-year-olds to 16-year-olds, compared with older adolescents (1.2 aOR)

Syphilis screening was more likely to occur for:

  • Women admitted to the hospital (4.6 aOR)
  • Non-Latino African American women (1.8 aOR)
  • Uninsured women (1.6 aOR)
  • Women with public insurance (1.4 aOR)
  • 12-year-olds to 16-year-olds (1.1 aOR)

“We know that 20 percent of the nearly 1 million cases of PID that are diagnosed each year occur in young women, with the majority of diagnoses made in EDs. It is encouraging that HIV and syphilis screening rates for women with PID increased over the study period. However, our findings point to missed opportunities to safeguard young women’s reproductive health,” says Monika K. Goyal, M.D., M.S.C.E., assistant professor of Pediatrics and Emergency Medicine and the study’s senior author. “Such discrepancies in screening across the 48 hospitals we studied underscore the need for a standardized approach to sexually transmitted infection (STI) screening.”

Untreated STIs can cause PID, an infection of a woman’s reproductive organs that can complicate her ability to get pregnant and also can cause infertility. Since 2006, the Centers for Disease Control and Prevention (CDC) has recommended that all women diagnosed with PID be tested for HIV. The CDC’s treatment guidelines also recommend screening people at high risk for syphilis.

“Syphilis infection rates have steadily increased each year, and it is now most prevalent among young adults,” Dr. Goyal says. “Future research should examine how STI screening can be improved in emergency departments, especially since adolescents at high risk for STIs often access health care through EDs. We also should explore innovative approaches, including electronic alerts and shared decision-making to boost STI screening rates for young women.”

In addition to Dr. Goyal, Children’s study co-authors include Lead Author, Amanda Jichlinski, M.D.; and co-authors, Gia Badolato, M.P.H., and William Pastor, M.A., M.P.H.

The ‘secret sauce’ for high-performing NICUs

Lamia Soghier and Billie Lou Short

Quoting the literature, Lamia Soghier, M.D., Children’s NICU medical unit director, and Billie Lou Short, M.D., chief of Children’s Division of Neonatology, write that hospitals with strong performance-improvement programs share eight critical factors in common.

Leaders of neonatal intensive care units (NICUs) across the nation share the same play books as they strive to provide safe, high-quality medical and surgical care for vulnerable newborns. A growing number of quality collaborations share best practices and evidence-based guidelines across the nation in the hopes of replicating quality and safety success stories while minimizing harms.

Still, NICUs that use similar interventions in similar fashions often do not achieve identical results.

“This unexplained variability in outcomes between NICUs begs the question: What is the secret sauce? Why do some NICUs consistently outshine others in spite of the application of the same ‘potentially best practices,’ ” the leaders of Children’s award-winning NICU ask in an editorial published online July 12, 2018, by Archives of Disease in Childhood (ADC) – Fetal & Neonatal edition.

Quoting the literature, Lamia Soghier, M.D., Children’s NICU medical unit director, and Billie Lou Short, M.D., chief of Children’s Division of Neonatology, write that hospitals with strong performance-improvement programs share eight critical factors in common:

  • Strong performance-improvement leadership at the administrative and executive levels
  • Boards of Trustees who are actively involved and provide continuity in vision regardless of changes in senior hospital leadership
  • An effective oversight structure that avoids duplicating efforts
  • Expert performance-improvement staff who are trained in quality and safety and able to carry out projects successfully
  • Physicians who are involved and held accountable
  • Staff who are actively involved
  • Effective use of data in decision-making
  • Effective communication strategies for all stakeholders

The “‘secret sauce’ may lie in establishing systems that promote the culture of quality and safety rather than waiting for a reduction in morbidity,” write Drs. Soghier and Short.

For the second year running, Children’s neonatology division ranked No. 1 among NICUs ranked by U.S. News & World Report. Despite challenges inherent in being a “busy level IV NICU in a free-standing children’s hospital with a rapidly growing capacity, higher levels of complex patients, [the] presence of trainees on rounds and routine 3:1 and 2:1 staffing models,” Children’s NICU has continued to have the lowest rates of such objective quality measures as central line-associated bloodstream infections and unintended extubations, they write.

“We attribute our success to direct involvement of all levels of leadership in our unit in [performance improvement] PI initiatives, a dedicated local PI team, quality trained medical unit director, engagement of front-line staff in PI, the presence of local subject-matter experts, multidisciplinary diverse team both within the NICU and with other departments that bring an array of experiences and opinions and a supportive data infrastructure through local information technology, and use of the Children’s Hospital Neonatal Database that allows benchmarking to other non-delivery NICUs, Drs. Soghier and Short write. “Our team finds motivation in solving local issues routine in our work, and leadership prioritises these issues and promotes engagement of front-line staff.”

The commentary was a companion to “Using a Composite Morbidity Score and Cultural Survey to Explore Characteristics of High Proficiency Neonatal Intensive Care Units,” also published by ADC Fetal & Neonatal.

Making the grade: Children’s National is nation’s Top 5 children’s hospital

Additionally, for the second straight year, Children’s Neonatology division led by Billie Lou Short, M.D., ranked No. 1 among 50 neonatal intensive care units ranked across the nation.

Children’s National also ranked in the Top 10 in six additional services:

For the eighth year running, Children’s National ranked in all 10 specialty services, which underscores its unwavering commitment to excellence, continuous quality improvement and unmatched pediatric expertise throughout the organization.

“It’s a distinct honor for Children’s physicians, nurses and employees to be recognized as the nation’s Top 5 pediatric hospital. Children’s National provides the nation’s best care for kids and our dedicated physicians, neonatologists, surgeons, neuroscientists and other specialists, nurses and other clinical support teams are the reason why,” says Kurt Newman, M.D., Children’s President and CEO. “All of the Children’s staff is committed to ensuring that our kids and families enjoy the very best health outcomes today and for the rest of their lives.”

The excellence of Children’s care is made possible by our research insights and clinical innovations. In addition to being named to the U.S. News Honor Roll, a distinction awarded to just 10 children’s centers around the nation, Children’s National is a two-time Magnet® designated hospital for excellence in nursing and is a Leapfrog Group Top Hospital. Children’s ranks seventh among pediatric hospitals in funding from the National Institutes of Health, with a combined $40 million in direct and indirect funding, and transfers the latest research insights from the bench to patients’ bedsides.

“The 10 pediatric centers on this year’s Best Children’s Hospitals Honor Roll deliver exceptional care across a range of specialties and deserve to be highlighted,” says Ben Harder, chief of health analysis at U.S. News. “Day after day, these hospitals provide state-of-the-art medical expertise to children with complex conditions. Their U.S. News’ rankings reflect their commitment to providing high-quality care.”

The 12th annual rankings recognize the top 50 pediatric facilities across the U.S. in 10 pediatric specialties: cancer, cardiology and heart surgery, diabetes and endocrinology, gastroenterology and gastrointestinal surgery, neonatology, nephrology, neurology and neurosurgery, orthopedics, pulmonology and urology. Hospitals received points for being ranked in a specialty, and higher-ranking hospitals receive more points. The Best Children’s Hospitals Honor Roll recognizes the 10 hospitals that received the most points overall.

This year’s rankings will be published in the U.S. News & World Report’s “Best Hospitals 2019” guidebook, available for purchase in late September.

Potential to replace race as a risk factor for kidney-transplant failure

Marva Moxey-Mims in her office at Children's National.

Marva Moxey-Mims, M.D., FASN, says APOLLO study researchers hope that clarifying the role of the APOL1 gene in kidney-transplant failure could lead to fewer discarded kidneys, which could boost the number of available kidneys for patients awaiting transplants.

Right now, more than 100,000 adult and pediatric patients in the U.S. are waiting for a life-saving kidney donation. Thirteen of them die each day while awaiting a transplant. However, a significant portion of kidneys from deceased donors are discarded because they literally don’t make the grade – a scoring system known as the kidney donor profile index (KDPI) that aims to predict how long a donor kidney will last in an intended recipient based on a variety of factors, including the donor’s age, size and health history.

Ethnicity and race are also part of that scoring system, explains Marva Moxey-Mims, M.D., FASN, chief of the Division of Nephrology at Children’s National Health System. That’s partly because research over the years has suggested that kidneys from certain racial groups, including African-Americans, may not have the same longevity as those from other groups.

But race might not be the right marker to consider, Dr. Moxey-Mims counters. More recent studies have shown that a particular gene known as APOL1 might better predict risk of kidney-transplant failure. APOL1 high-risk variants are associated with a wide range of kidney diseases, with retrospective studies suggesting that they could be a key cause of failure in some donated kidneys. Although this gene is found almost exclusively in people of recent African descent, only about 13 percent of that population has high-risk APOL1 variants that might cause kidney problems.

“Instead of putting all African-American donor kidneys in one proverbial ‘bucket,’ we might be able to use this gene to determine if they truly carry a higher risk of early failure,” Dr. Moxey-Mims says.

To more definitively confirm whether this gene could be used as a proxy for heightened kidney-failure risk, Dr. Moxey-Mims and colleagues across the country are participating in the APOL1 Long-Term Kidney Transplantation Outcomes Network (APOLLO) study, she and Dr. Barry Freedman explain in a perspective published online April 27, 2018, in Clinical Journal of the American Society of Nephrology. The APOLLO study will tap people accessing the hundreds of transplant centers scattered across the nation, prospectively genotyping deceased and living African-American kidney donors as well as kidney-transplant recipients to assess whether they carry high-risk APOL1 gene variants. Living donors and transplant recipients will be followed for years to gauge how their kidneys fare over time.

The researchers, Dr. Moxey-Mims explains, hope to answer whether the APOL1 high-risk gene variants in donor kidneys could replace race as a risk factor when calculating the KDPI score and whether recipients’ own APOL1 gene variants impact transplant failure risk. They also hope to better understand the risk to living donors. “If a living donor has an increased risk of kidney failure,” she adds, “he or she can make a more educated decision about whether to donate a kidney.”

Dr. Moxey-Mims plays a pivotal role as the chair of the study’s steering committee, a group made up of the study’s principal investigators at all 13 clinical sites and the Data Coordinating Center, as well as the program officials from the National Institutes of Health funding institutes (National Institute of Diabetes and Digestive and Kidney Diseases, National Institute of Allergy and Infectious Diseases, and National Institute on Minority Health and Health Disparities). She will play a key part in helping to ensure that the study stays on track with recruitment goals, as well as publicizing the study at national meetings.

The study also includes a Community Advisory Council, a group made up of stakeholders in this study: 26 African-Americans who either have donated a kidney, received a kidney donation, are on dialysis awaiting a kidney transplant, or have a close relative in one of those categories. This group has helped to steer the study design in multiple ways, Dr. Moxey-Mims explains. For example, they have worked with study leaders to simplify the language on consent forms, helped to delineate which data study participants might want to receive when the study is completed, and helped to publicize the study in their communities by giving talks at churches and other venues.

Eventually, Dr. Moxey-Mims says APOLLO study researchers hope that clarifying the role of the APOL1 gene in kidney-transplant failure could lead to fewer discarded kidneys, which could boost the number of available kidneys for patients awaiting transplants.

“Down the road, the pool of patients awaiting transplant might have access to more kidneys because available organs aren’t getting a bad score simply because the donor is African-American,” she says. “We hope this might shorten the wait for some patients and their families who are desperate to get that call that a kidney is finally available.”

Financial support for research reported in the post was provided by the National Institutes of Health under grant numbers R01 DK084149, R01 DK070941 and U01 DK116041.

Keeping an eye on autonomic function for infants with HIE

An-Massaro

“By including heart rate variability measurements and other markers of autonomic function in our current predictive armamentarium,” says An Massaro, M.D., “we may be able to offer new hope for infants with HIE.”

In about two to three in every 1,000 full-term births, babies develop a neurological condition called hypoxic ischemic encephalopathy (HIE) when their brains receive insufficient oxygen. HIE can be a devastating condition, leading to severe developmental or cognitive delays or motor impairments that become more evident as the child grows older. Despite improvements in care – including therapeutic hypothermia, a whole-body cooling method administered shortly after birth that can slow brain damage – about half of children with this condition die from neurological complications by age 2.

Finding ways to identify children with the most severe HIE could help researchers focus their efforts and provide even more intense neuroprotective care, explains An Massaro, M.D., a neonatologist at Children’s National Health System. But thus far, it’s been unclear which symptoms reflect the extent of HIE-induced brain damage.

That’s why Dr. Massaro and colleagues embarked on a study published in the May 2018 issue of Journal of Pediatrics. The team sought to determine whether dysfunction of the autonomic nervous system (ANS) – the auto-pilot part of the nervous system responsible for unconscious bodily functions, such as breathing and digestion – reflected in routine care events can be used as a marker for brain injury severity.

The researchers collected data from 25 infants who were treated for HIE with therapeutic hypothermia at Children’s National. Thanks to multi-modal monitoring, these babies’ medical records hold a treasure trove of information, explains Rathinaswamy B. Govindan, Ph.D., a staff scientist in Children’s Advanced Physiological Signals Processing Lab.

In addition to including continuous heart rate tracings and blood pressure readings that are standard for many infants in the neonatal intensive care unit (NICU), they also recorded cerebral near infrared spectroscopy, a monitor that measures brain tissue oxygen levels. The investigators performed detailed analyses to evaluate how these monitor readings change in response to a variety of routine care events, such as diaper changes, heel sticks, endotracheal tube manipulations and pupil examinations.

The researchers stratified these infants based on how dysfunctional their ANS behaved by using heart rate variability as a marker: The fewer natural fluctuations in heart rate, the more damaged their ANS was thought to be. And they also used non-invasive brain magnetic resonance imaging (MRI) to determine brain damage. They then compared this information with the babies’ physiological responses during each care event.

Their findings show that infants with impaired ANS, based on depressed heart rate variability before the care event, had significantly different responses to these care events compared with babies with intact ANS.

  • For stimulating interventions, such as diaper changes and heel sticks, both heart rate and blood pressure increased in babies with intact ANS but decreased in babies with impaired ones.
  • Shining a light in their pupils led to an expected decreased heart rate with stable blood pressure in ANS-intact infants, but in ANS-impaired infants, there was no responsive change in heart rate and, additionally, a decrease in blood pressure was observed.
  • Responses were similar between the two groups during breathing tube manipulations, except for a slight increase in heart rate a few minutes later in the ANS-impaired group.

These results, Govindan explains, suggest that a real-time, continuous way to assess ANS function may offer insights into the expected physiological response for a given infant during routine NICU care.

“This is exactly the type of additional information that intensivists need to pinpoint infants who may benefit from additional neuroprotective support,” he says. “Right now, it is standard practice to monitor brain activity continuously using electroencephalogram and to check the status of the brain using MRI to assess the response to therapeutic cooling. Neither of these assessments can be readily used by neonatologists at the bedside in real-time to make clinical decisions.”

Assessing ANS function in real-time can help guide neuroprotective care in high-risk newborns by providing insight into the evolving nature of brain damage in these infants, Dr. Massaro adds.

Beyond simply serving as a biomarker into brain injury, poor ANS function also could contribute to the development of secondary injury in newborns with HIE by stymieing the normal changes in heart rate and blood pressure that help oxygenate and heal injured brains. The researchers found that the cumulative duration of autonomic impairment was significantly correlated with the severity of brain injury visible by MRI in this group of infants.

“By including heart rate variability measurements and other markers of autonomic function in our current predictive armamentarium,” says Dr. Massaro, “we may be able to offer new hope for infants with HIE.”

Baby in the NICU

Getting to the heart of cardiac output

Baby in the NICU

To keep infants in the neonatal intensive care unit (NICU) as healthy as possible, it’s important to keep close tabs on their vital signs. During their NICU stay, most babies have continuous monitoring of their blood pressure, respiratory rate and blood oxygen saturation. And although continuous monitoring of heart rate is also typically standard, other information about heart function – such as cardiac output, a measure of how well the heart is pumping blood – remains a challenge to obtain in these vulnerable babies.

Clinical markers like blood pressure, heart rate and urine output are available, but they are indirect measures of cardiac output, how much blood the heart pumps per minute. Less invasive techniques, such as Doppler ultrasound, can be imprecise. Respiratory mass spectrometry or catherization would provide more precision by directly calcuating cardiac output but carry risks or are not feasible for neonates.

Clinicians at Children’s National Health System hypothesized that COstatus monitors could offer a way to directly measure cardiac output among neonates. The COstatus monitor – a minimally invasive way to measure hemodynamics – captures cardiac output, total end diastolic volume, active circulation volume and central blood volume.

The research team tested the approach by leveraging ultrasound dilution: Injecting saline, which has an ultrasound velocity of 1533m/second, slows the ultrasound velocity of blood from its normal rate of 1580m/second and produces a dilution curve.

“It is feasible to directly measure neonatal cardiac output by ultrasound dilution via the COstatus monitor in the first two weeks of life with no adverse events,” says Khodayar Rais-Bahrami, M.D., a Children’s neonatologist and senior author for the research presented during the Pediatric Academic Societies 2018 annual meeting. “When we took consecutive measurements, we saw very little variance in the parameters.”

The COstatus monitor uses an extracorporeal loop that is connected to arterial and venous catheters. The 12 neonates included in the study already had umbilical venous catheters as well as either a peripheral arterial line or umbilical arterial catheter. The infants ranged in weight from 0.72 to 3.74 kg and were born at 24 to 41.3 gestational weeks.

The infants’ cardiac output was measured 54 times from 1 to 13 days of life. Up to two measurement sessions occurred daily for a maximum of four days. The mean cardiac output was 0.43 L/minute with a mean cardiac index of 197mL/kg/minute.

Future research will describe normal cardiac output ranges for neonates as well as how these measurements evolve during the first week of life.

In addition to Dr. Rais-Bahrami, study co-authors include Simranjeet S. Sran, M.D., and Mariam Said, M.D., a Children’s neonatologist.

Preemie Baby

Brain food for preemies

Preemie Baby

Babies born prematurely – before 37 weeks of pregnancy – often have a lot of catching up to do. Not just in size. Preterm infants typically lag behind their term peers in a variety of areas as they grow up, including motor development, behavior and school performance.

New research suggests one way to combat this problem. The study, led by Children’s researchers and presented during the Pediatric Academic Societies 2018 annual meeting, suggests that the volume of carbohydrates, proteins, lipids and calories consumed by very vulnerable premature infants significantly contributes to increased brain volume and white matter development, even though additional research is needed to determine specific nutritional approaches that best support these infants’ developing brains.

During the final weeks of pregnancy, the fetal brain undergoes an unprecedented growth spurt, dramatically increasing in volume as well as structural complexity as the fetus approaches full term.

One in 10 infants born in the U.S. in 2016 was born before 37 weeks of gestation, according to the Centers for Disease Control and Prevention. Within this group, very low birthweight preemies are at significant risk for growth failure and neurocognitive impairment. Nutritional support in the neonatal intensive care unit (NICU) helps to encourage optimal brain development among preterm infants. However, their brain growth rates still lag behind those seen in full-term newborns.

“Few studies have investigated the impact of early macronutrient and caloric intake on microstructural brain development in vulnerable preterm infants,” says Katherine Ottolini, lead author of the Children’s-led study. “Advanced quantitative magnetic resonance imaging (MRI) techniques may help to fill that data gap in order to better direct targeted interventions to newborns who are most in need.”

The research team at Children’s National Health System enrolled 69 infants who were born younger than 32 gestational weeks and weighed less than 1,500 grams. The infants’ mean birth weight was 970 grams and their mean gestational age at birth was 27.6 weeks.

The newborns underwent MRI at their term-equivalent age, 40 weeks gestation. Parametric maps were generated for fractional anisotropy in regions of the cerebrum and cerebellum for diffusion tensor imaging analyses, which measures brain connectivity and white matter tract integrity. The research team also tracked nutritional data: Grams per kilogram of carbohydrates, proteins, lipids and overall caloric intake.

“We found a significantly negative association between fractional anisotropy and cumulative macronutrient/caloric intake,” says Catherine Limperopoulos, Ph.D., director of Children’s Developing Brain Research Laboratory and senior author of the research. “Curiously, we also find significantly negative association between macronutrient/caloric intake and regional brain volume in the cortical and deep gray matter, cerebellum and brainstem.”

Because the nutritional support does contribute to cerebral volumes and white matter microstructural development in very vulnerable newborns, Limperopoulos says the significant negative associations seen in this study may reflect the longer period of time these infants relied on nutritional support in the NICU.

In addition to Ottolini and Limperopoulos, study co-authors include Nickie Andescavage, M.D., Attending, Children’s Neonatal-Perinatal Medicine; and Kushal Kapse.

Examining BPA’s impact on developing heart cells

Nikki Gillum Posnack

“We know that once this chemical enters the body, it can be bioactive and therefore can influence how heart cells function,” says Nikki Gillum Posnack, Ph.D. “This is the first study to look at the impact BPA exposure can have on heart cells that are still developing.”

More than 8 million pounds of bisphenol A (BPA), a common chemical used in manufacturing plastics, is produced each year for consumer goods and medical products. This endocrine disruptor reaches 90 percent of the population, and excessive exposure to BPA, e.g., plastic bottles, cash register receipts, and even deodorant, is associated with adverse cardiovascular events that range from heart arrhythmias and angina to atherosclerosis, the leading cause of death in the U.S.

To examine the impact BPA could have in children, researchers with Children’s National Heart Institute and the Sheikh Zayed Institute for Pediatric Surgical Innovation evaluated the short-term risks of BPA exposure in a preclinical setting. This experimental research finds developing heart cells respond to short-term BPA exposure with slowed heart rates, irregular heart rhythms and calcium instabilities.

While more research is needed to provide clinical recommendations, this preclinical model paves the way for future study designs to see if young patients exposed to BPA from medical devices or surgical procedures have adverse cardiac events and altered cardiac function.

“Existing research explores the impact endocrine disruptors, specifically BPA, have on adults and their cardiovascular and kidney function,” notes Nikki Gillum Posnack, Ph.D., a study author and assistant professor at Children’s National and The George Washington University. “We know that once this chemical enters the body, it can be bioactive and therefore can influence how heart cells function. This is the first study to look at the impact BPA exposure can have on heart cells that are still developing.”

The significance of this research is that plastics have revolutionized the way clinicians and surgeons treat young patients, especially patients with compromised immune or cardiac function.

Implications of Dr. Posnack’s future research may incentivize the development of alternative products used by medical device manufacturers and encourage the research community to study the impact of plastics on sensitive patient populations.

“It’s too early to tell how this research will impact the development of medical devices and equipment used in intensive care settings,” notes Dr. Posnack. “We do not want to interfere with clinical treatments, but, as scientists, we are curious about how medical products and materials can be improved. We are extending this research right now by examining the impact of short-term BPA exposure on human heart cells, which are developed from stem cells.”

This research, which appears as an online advance in Nature’s Scientific Reports, was supported by the National Institutes of Health under awards R00ES023477, RO1HL139472 and UL1TR000075, Children’s Research Institute and the Children’s National Heart Institute. NVIDIA Corporation provided GPUs, computational devices, for this study.

Keeping kids with asthma out of the hospital

inhaler

Pediatric asthma takes a heavy toll on patients and families alike. Affecting more than 7 million children in the U.S., it’s the most common nonsurgical diagnosis for pediatric hospital admission, with costs of more than $570 million annually. Understanding how to care for these young patients has significantly improved in the last several decades, leading the National Institutes of Health (NIH) to issue evidence-based guidelines on pediatric asthma in 1990. Despite knowing more about this respiratory ailment, overall morbidity – measured by attack rates, pediatric emergency department visits or hospitalizations – has not decreased over the last decade.

“We know how to effectively treat pediatric asthma,” says Kavita Parikh, M.D., M.S.H.S., a pediatric hospitalist at Children’s National Health System. “There’s been a huge investment in terms of quality improvements that’s reflected in how many papers there are about this topic in the literature.”

However, Dr. Parikh notes, most of those quality-improvement papers do not focus on inpatient discharge, a particularly vulnerable time for patients. Up to 40 percent of children who are hospitalized for asthma-related concerns come back through the emergency department within one year. One-quarter of those kids are readmitted.

“It’s clear that we need to do better at keeping kids with asthma out of the hospital. The point at which they’re being discharged might be an effective time to intervene,” Dr. Parikh adds.

To determine which interventions hold promise, Dr. Parikh and colleagues recently performed a systematic review of studies involving quality improvements after inpatient discharge. They published their findings in the May 2018 edition of the journal, Pediatrics. Because May is National Asthma and Allergy Awareness month, she adds, it’s a timely fit.

The researchers combed the literature, looking for research that tested various interventions at the point of discharge for their effect on hospital readmission anywhere from fewer than 30 days after discharge to up to one year later. They specifically searched for papers published from 1991, the year after the NIH issued its original asthma care guidelines, until November 2016.

Their search netted 30 articles that met these criteria. A more thorough review of each of these studies revealed common themes to interventions implemented at discharge:

  • Nine studies focused on standardization of care, such as introducing or revising a specific clinical pathway
  • Nine studies focused on education, such as teaching patients and their families better self-management strategies
  • Five studies focused on tools for discharge planning, such as ensuring kids had medications in-hand at the time of discharge or assigning a case manager to navigate barriers to care and
  • Seven studies looked at the effect of multimodal interventions that combined any of these themes.

When Dr. Parikh and colleagues examined the effects of each type of intervention on hospital readmission, they came to a stunning conclusion: No single category of intervention seemed to have any effect. Only multimodal interventions that combined multiple categories were effective at reducing the risk of readmission between 30 days and one year after initial discharge.

“It’s indicative of what we have personally seen in quality-improvement efforts here at Children’s National,” Dr. Parikh says. “With a complex condition like asthma, it’s difficult for a single change in how this disease is managed to make a big difference. We need complex and multimodal programs to improve pediatric asthma outcomes, particularly when there’s a transfer of care like when patients are discharged and return home.”

One intervention that showed promise in their qualitative analysis of these studies, Dr. Parikh adds, is ensuring patients are discharged with medications in hand—a strategy that also has been examined at Children’s National. In Children’s focus groups, patients and their families have spoken about how having medications with them when they leave the hospital can boost compliance in taking them and avoid difficulties is getting to an outside pharmacy after discharge. Sometimes, they have said, the chaos of returning home can stymie efforts to stay on track with care, despite their best efforts. Anything that can ease that burden may help improve outcomes, Dr. Parikh says.

“We’re going to need to try many different strategies to reduce readmission rates, engaging different stakeholders in the inpatient and outpatient side,” she adds. “There’s a lot of room for improvement.”

In addition to Dr. Parikh, study co-authors include Susan Keller, MLS, MS-HIT, Children’s National; and Shawn Ralston, M.D., M.Sc., Children’s Hospital of Dartmouth-Hitchcock.

Collaborative approach to NICU care leads to improved quality and safety across hospitals

Brian Stone with baby

Parents with sick or premature newborns want and need the best care possible, making quality and safety in the neonatal intensive care unit (NICU) a top priority. Over the past decade, Children’s National Health System has provided top quality NICU care to the Washington, D.C. community and surrounding areas. As part of this commitment, the institution developed an extensive network of partnerships in the Mid-Atlantic region where Children’s National neonatologists and advanced practice providers collaborate with other hospitals in the region to share best practices in the NICU.

Together, Children’s National and partner hospitals aim to improve NICU care for patients and families. To carry out this commitment, Children’s National neonatologists fully integrate themselves into local community hospitals to provide services such as neonatal care, delivery room attendance, consultations to obstetricians and local pediatricians, and serve as educators to the hospital team.

Integrating pediatric specialists into community hospitals that treat both adults and children helps strengthen the infrastructure and refine practices to specifically understand pediatric biology and development to enhance existing care. Using the Dyad leadership model, the team forms interdisciplinary care committees, led by a physician and nursing champion, to empower everyone who interacts with the NICU and has a stake in a child’s care. All policies and procedures are vetted by these committees to ensure high-quality, cohesive care for the patient.

Through this collaboration, Children’s National neonatologists oversee newborn care for more than 10,000 births per year. Outcomes include:

  • Partner NICUs consistently perform in the top quartile for key performance benchmarking measures in national networks.
  • Partner NICUs have lower than predicted rates of morbidity, infection, lung disease and necrotizing enterocolitis which are major determinants in overall neonatal outcome.

Based on this success, Children’s National created the Division of Pediatric Outreach in 2017, led by Brian Stone, M.D., M.B.A. This division focuses on ensuring that neonatal and pediatric patients have access to and can receive expert care from Children’s National specialists in their local community birth hospital. Additionally, the division works closely with local obstetricians and maternal-fetal-medicine specialists to develop birth and post-natal plans for high-risk pregnancies to ensure that newborns have the best possible start.

“Over the years, we have been able to leverage our internal expertise as reflected in our current number one ranking in U.S. News & World Report and extend the same high level of care to patients born within our extended network to improve population health as a whole within the region,” said Dr. Stone.

Children’s Community Health Track receives prestigious APA Teaching Program Award

Cara Lichtenstein

“As a community-focused health system, one of our central missions is to train a new generation of residents to create successful community partnerships and integrate public health concepts into the everyday practice of medicine to improve the health of underserved communities,” says Cara Lichtenstein, M.D., MPH.

The Children’s National Community Health Track (CHT) has been recognized by the Academic Pediatric Association with its prestigious Teaching Program Award. The honor was made public at the Pediatric Academic Societies (PAS) annual meeting on May 7, 2018 in Toronto, Ontario. The purpose of the award is to foster interest in the teaching of general pediatrics by giving national recognition to an outstanding general pediatric program. The PAS selection committee chose Children’s CHT for demonstrating excellence in educational teaching methods, acceptance by the community, its adaptability and the outstanding quality of residents trained in the program.

“As a community-focused health system, one of our central missions is to train a new generation of residents to create successful community partnerships and integrate public health concepts into the everyday practice of medicine to improve the health of underserved communities,” says Cara Lichtenstein, M.D., MPH and director of Children’s Community Health Track.

Children’s CHT focuses on underserved populations and the development of skills in health policy, advocacy and community healthcare delivery. Residents spend their outpatient time learning to use public health techniques to identify and address community health needs, becoming a physician advocate and learning more about the sociocultural determinants of health and health disparities. Training for CHT is integrated with Children’s overall pediatrics residency program to ensure excellence in attainment of clinical skills, and to allow residents the opportunity to work with Children’s top-rated primary care, specialty and hospital-based physicians and care teams.

This is the third time in recent years that Children’s National has been honored by the Academic Pediatric Association. In 2013, Mary Ottolini, M.D., MPH and vice chair of medical education was recognized for her leadership of Children’s Master Teacher Leadership Development program. In 2009, Denice Cora-Bramble, M.D., MBA accepted the APA Health Care Delivery Award for the Goldberg Center for Community Pediatric Health at Children’s National.

Children’s offers up to eight residency positions each year designated as Community Health Track positions. The goals of the track are centered on the core competencies of community pediatrics as described by the American Academy of Pediatrics. Primarily to train residents to:

  • Grasp the breadth of diversity inherent in the pediatric population and be familiar with health-related implications of cultural beliefs and practices of groups represented in the community.
  • Recognize the role of the pediatrician in identifying needs and facilitating access to resources for patients, families and communities.
  • Be aware of the risks to health and barriers to care for underserved children in Washington, D.C., and demonstrate skill in improving access to continuous comprehensive health maintenance.
  • Appreciate key issues related to the pediatrician’s role and interactions with local community agencies and advocacy groups.
  • Value the role of schools and childcare settings in supporting the educational and psychosocial development of children and adolescents.
  • Apply key principles about health promotion and disease prevention for children and adolescents over a set period of time.
  • Observe, interpret and report observations about the communities in which they serve.

The fundamental difference in this track compared to the more traditional Categorical Track lies in the outpatient experiences that occur in all three years of training. The CHT utilizes these outpatient experiences to help residents to attain a well-rounded community pediatrics experience.

“Washington, D.C. is an incredibly diverse community with large numbers of vulnerable children and families from D.C. and all over the world. Given our location in our nation’s capital, residents and faculty have the unique opportunity to work with national professional and advocacy organizations that are influencing policy – both locally and nationally – as it relates to children, families and health care,” says Mark Weissman, M.D., chief of general pediatrics and community health at Children’s National. “We’re thrilled to be recognized with the Academic Pediatric Association’s Teaching Program Award and grateful to Dr. Lichtenstein for her leadership and commitment to improving the health of D.C.’s children and training the next generation of pediatricians and advocates.”

Research and Education Week awardees embody the diverse power of innovation

cnmc-research-education-week

“Diversity powers innovation” was brought to life at Children’s National April 16 to 20, 2018, during the eighth annual Research and Education Week. Children’s faculty were honored as President’s Award winners and for exhibiting outstanding mentorship, while more than 360 scientific poster presentations were displayed throughout the Main Atrium.

Two clinical researchers received Mentorship Awards for excellence in fostering the development of junior faculty. Lauren Kenworthy, Ph.D received the award for Translational Science and Murray M. Pollack, M.D., M.B.A., was recognized in the Clinical Science category as part of Children’s National Health System’s Research and Education Week 2018.

Dr. Kenworthy has devoted her career to improving the lives of people on the autism spectrum and was cited by former mentees as an inspirational and tireless counselor. Her mentorship led to promising new lines of research investigating methods for engaging culturally diverse families in autism studies, as well as the impact of dual language exposure on cognition in autism.

Meanwhile, Dr. Pollack was honored for his enduring focus on motivating early-career professionals to investigate outcomes in pediatric critical care, emergency medicine and neonatology. Dr. Pollack is one of the founders of the Collaborative Pediatric Critical Care Research Network. He developed PRISM 1 and 2, which has revolutionized pediatric intensive care by providing a methodology to predict mortality and outcome using standardly collected clinical data. Mentees credit Dr. Pollack with helping them develop critical thinking skills and encouraging them to address creativity and focus in their research agenda.

In addition to the Mentorship and President’s Awards, 34 other Children’s National faculty, residents, interns and research staff were among the winners of Poster Presentation awards. The event is a celebration of the commitment to improving pediatric health in the form of education, research, scholarship and innovation that occurs every day at Children’s National.

Children’s Research Institute (CRI) served as host for the week’s events to showcase the breadth of research and education programs occurring within the entire health system, along with the rich demographic and cultural origins of the teams that make up Children’s National. The lineup of events included scientific poster presentations, as well as a full slate of guest lectures, educational workshops and panel discussions.

“It’s critical that we provide pathways for young people of all backgrounds to pursue careers in science and medicine,” says Vittorio Gallo, Ph.D., Children’s chief research officer and CRI’s scientific director. “In an accelerated global research and health care environment, internationalization of innovation requires an understanding of cultural diversity and inclusion of different mindsets and broader spectrums of perspectives and expertise from a wide range of networks,” Gallo adds.

“Here at Children’s National we want our current and future clinician-researchers to reflect the patients we serve, which is why our emphasis this year was on harnessing diversity and inclusion as tools to power innovation,” says Mark L. Batshaw, M.D., physician-in-chief and chief academic officer of Children’s National.

“Research and Education Week 2018 presented a perfect opportunity to celebrate the work of our diverse research, education and care teams, who have come together to find innovative solutions by working with local, national and international partners. This event highlights the ingenuity and inspiration that our researchers contribute to our mission of healing children,” Dr. Batshaw concludes.

Awards for the best posters were distributed according to the following categories:

  • Basic and translational science
  • Quality and performance improvement
  • Clinical research
  • Community-based research and
  • Education, training and program development.

Each winner illustrated promising advances in the development of new therapies, diagnostics and medical devices.

ER Nurse

An unexpected discovery in a central line

ER Nurse

About a year and a half ago, a 6-year-old boy arrived at Children’s Emergency Department after accidently removing his own gastrointestinal feeding tube. He wasn’t a stranger to Children’s National Health System: This young patient had spent plenty of time at the hospital since birth. Diagnosed in infancy with an intestinal pseudo-obstruction, a rare condition in which his bowels acted as if there were a blockage even though one was not present, parts of his intestine died and had been removed through multiple surgeries.

Because of this issue and associated health problems, at 4 years old he had a central line placed in a large vein that leads to his heart. That replaced other central lines placed in his neck earlier after those repeatedly broke. This latest central line in his chest als0 had frequent breaks. It also had become infected with multidrug-resistant Klebsiella bacteria two years before he was treated at Children’s National for inadvertently removing his feeding tube.

On that day, he seemed otherwise well. His exam was relatively unremarkable, except for a small leak in his central line and a slight fever. Those findings triggered cultures taken both from blood flowing through his central line and the surrounding skin.

“No one expected him to grow anything from these cultures, especially from a child who looked so healthy,” explains Madan Kumar, a fellow in Children’s division of Pediatric Infectious Disease and a member of the child’s care team. But a mold grew prolifically. Further investigation from a sample sent to the National Institutes of Health showed that it was a relatively new species known as Mucor velutinosus.

Because such an infection had never been reported in a child whose immune system wasn’t extremely compromised from cancer, Kumar and team decided to publish a case report. The study appeared online Jan. 24, 2018, in the Journal of the Pediatric Infectious Diseases Society.

Kumar notes that this patient faced myriad challenges. Not only did he have a central line, but the line also had numerous problems, necessitating fixes that could increase the chance of infection. Additionally, because of his intestinal issues, he had a chronic problem with malabsorption of nutrients. Patients with this issue often are treated liberally with antibiotics. Although this intervention can kill “bad” bacteria that can cause an infection, they also knock out “good” bacteria that keep other microorganisms – like fungi – in check. On top of all of this, the patient was receiving a nutrient-rich formula in his central line to boost his caloric intake, yet another factor associated with infections.

Patients who develop this specific fungal infection are overwhelmingly adults who are immunocompromised, Kumar explains, including those with diabetes, transplant recipients, patients with cancer and those who have abnormally low concentrations of immune cells called neutrophils in their blood. The only children who tend to get this infection are preterm infants of very low birth weight who haven’t yet developed a robust immune response.

Because there was only one other published case report about a child with M. velutinosus – a 1-year-old with brain cancer who had undergone a bone marrow transplant – Kumar notes that he and colleagues were at a loss as to how best to treat their patient. “There’s a paucity of literature on what to do in a case like this,” he says.

Fortunately, the treatment they selected was successful. As soon as the cultures came back positive for this mold, the patient went on a three-week course of an antifungal drug known as amphotericin B. Surgeons also removed his infected central line and placed a new one. These efforts cured the patient’s infection and prevented it from spreading and potentially causing the multi-organ failure associated with these types of infections.

This case taught Kumar and colleagues quite a bit – knowledge that they wanted to share by publishing the case report. For example, it reinforces the importance of central line care. It also highlights the value of thoroughly investigating potential problems in a patient with risk factors, even one who appears otherwise healthy.

Finally, Kumar adds, the case emphasizes the importance of good antibiotic stewardship, which can help prevent patients from developing sometimes deadly secondary infections like this one. “This is not an organism that you see growing in a 6-year-old very often,” he says. “The fact that we saw it here speaks to the need to be judicious with broad-spectrum antibiotics so that we have a number of therapeutic options should we see unusual cases like this one.”

A new diagnostic tool led by Shireen Atabaki, M.D., M.P.H., helps prescribers determine if CT scans are necessary for children with head injuries through a checklist protocol.

Opportunities to improve the lives of children are increasingly found at the intersection of health and technology, a sweet spot for enhancing care in today’s connected world. A team of experts at Children’s National Health System launched several initiatives using health information technology to improve care delivery, earning the institution the prestigious 2017 HIMSS Enterprise Davies Award. Recognizing outstanding achievements of organizations that have utilized health IT to significantly improve patient outcomes while also achieving a return on investment, Children’s National received the award based on three case studies in particular:

  • Decreasing use of CAT scans by 44 percent – A new diagnostic tool led by Shireen Atabaki, M.D., M.P.H., emergency medicine specialist, incorporated into the electronic health record helps prescribers determine if CT scans are necessary for children with head injuries through a checklist protocol. The new tool reduced the rate of CT scan utilization by 44 percent – decreasing unnecessary radiation exposure for children and resulting in first-year cost savings of more than $875,000.
  • Innovative unit-based quality boards – These electronic boards provide health care teams and families with real-time quality and safety information. By having patient information readily available in one location, the boards improved medication reconciliation by 13 percent, decreased the time to patient consent by 49 percent, and reduced duration of urinary catheters by 11 percent.
  • Improved clinician documentation – To improve outcomes and reduce costs,

Children’s National transitioned from dictation/transcription-driven notes to electronic/voice recognition notes in ambulatory specialty clinics. This allowed for the immediate availability of notes to all care providers and a significant reduction in transcription costs.

These initiatives demonstrate the life-changing quality and safety efforts under way at Children’s National that put patient safety first. Brian Jacobs, M.D., vice president, chief medical information officer and chief information officer, accepted the award on behalf of Children’s National at the HIMSS Awards gala at the Wynn in Las Vegas in March.

STAT Madness

Voters select Children’s National innovation as runner-up in national competition

STAT Madness

Facial recognition technology developed and tested by researchers with the Sheikh Zayed Institute for Pediatric Surgical Innovation and Rare Disease Institute at Children’s National was the runner-up in this year’s STAT Madness 2018 competition.

Facial recognition technology developed and tested by researchers with the Sheikh Zayed Institute for Pediatric Surgical Innovation and Rare Disease Institute at Children’s National was the runner up in this year’s STAT Madness 2018 competition. Garnering more than 33,000 overall votes in the bracket-style battle that highlights the best biomedical advances, the Children’s National entry survived five rounds and made it to the championship before falling short of East Carolina University’s overall vote count.

Children’s entry demonstrates the potential widespread utility of digital dysmorphology technology to diverse populations with genetic conditions. The tool enables doctors and clinicians to identify children with genetic conditions earlier by simply taking the child’s photo with a smartphone and having it entered into a global database for computer analyses.

The researchers partnered with the National Institutes of Health National Human Genome Research Institute and clinicians from 20 different countries to acquire pictures from local doctors for the study. Using the facial analysis technology, they compared groups of Caucasians, Africans, Asians and Latin Americans with Down syndrome, 22q11.2 deletion syndrome (also called DiGeorge syndrome) and Noonan syndrome to those without it. Based on more than 125 individual facial features, they were able to correctly identify patients with the condition from each ethnic group with more than a 93 percent accuracy rate. Missed diagnoses of genetic conditions can negatively impact quality of life and lead to premature death.

Children’s National also was among four “Editor’s Pick” finalists, entries that span a diverse range of scientific disciplines. Journalists at the digital publication STAT pored through published journal articles for 64 submissions in the single-elimination contest to honor a select group of entries that were the most creative, novel, and most likely to benefit the biomedical field and the general public.

Each year, 1 million children are born worldwide with a genetic condition that requires immediate attention. Because many of these children experience serious medical complications and go on to suffer from intellectual disability, it is critical that doctors accurately diagnose genetic syndromes as early as possible.

“For years, research groups have viewed facial recognition technology as a potent tool to aid genetic diagnosis. Our project is unique because it offers the expertise of a virtual geneticist to general health care providers located anywhere in the world,” says Marius George Linguraru, D.Phil., M.A., M.S., a Sheikh Zayed Institute for Pediatric Surgical Innovation principal investigator who invented the technology. “Right now, children born in under-resourced regions of the U.S. or the world can wait years to receive an accurate diagnosis due to the lack of specialized genetic expertise in that region.”

In addition to providing patient-specific benefits, Marshall Summar, M.D., director of Children’s Rare Disease Institute that partners in the facial recognition technology research, says the project offers a wider societal benefit.

“Right now, parents can endure a seemingly endless odyssey as they struggle to understand why their child is different from peers,” says Dr. Summar. “A timely genetic diagnosis can dispel that uncertainty and replace it with knowledge that can speed patient triage and deliver timely medical interventions.”

Zeroing in on zero harm: Innovative quality and safety initiatives from Children’s National experts

Zeroing in on Zero Harm

Leaders at Children’s National Health System recently showcased innovative quality and safety initiatives on a national stage at the Children’s Hospital Association’s 2018 Quality and Safety in Children’s Health Conference.

Leaders at Children’s National Health System recently showcased innovative quality and safety initiatives on a national stage at the Children’s Hospital Association’s 2018 Quality and Safety in Children’s Health Conference. While collaborating with other medical professionals in the field, the team made an impact by sharing key projects implemented at Children’s National to enhance patient care and reduce harm, including:

    • Safety in Numbers: Driving 10,000 Good Catches – Presented by Rahul Shah, M.D., vice president, chief quality and safety officer, and Rebecca Cady, Esq, BSN, vice president, chief risk officer: Recognizing barriers to reporting safety events, Children’s National embarked upon a three-year corporate goal to double the number of safety event reports, ultimately leading to reduction of preventable harm. By promoting staff accountability and using incentives to drive reporting, incident reports more than doubled in a three-year time frame.
    • Moving from Disjointed Spreadsheets to a Real-Time Data Management System – Presented by Evan Hochberg, R.N., patient safety consultant, and Neil Bhattarai, C.S.T., process improvement consultant: Tracking hospital-acquired conditions (HACs) requires robust data capabilities, which is why Children’s National sought to improve its HAC data system with increased efficiencies and reduced delays in how staff presented data to the hospital. The team recognized opportunities to improve the management of HAC data, leading to the finding that increased real-time awareness of harm events while utilizing existing infrastructure can accelerate harm reduction.
    • Improving the Surgical Experience for Children with Autism – Presented by Terry Spearman, C.C.L.S., manager of child life services: Staff at Children’s National found that many patients with autism entering the operating room needed special support to make it through pre-op, complicating their path toward surgery and causing frustration for patients, families and the care team. The team solved this challenge by creating a system to identify patients before they arrived for surgery, which allowed staff to create a safe passage plan for each patient and to achieve better care coordination with all care team members. Titled “Help Me Keep Calm,” the hospital’s program provides a more peaceful and individualized experience for both the patient and his or her family.
    • IMPACT Session: Enhancing Psychological Safety to Improve the Safety Climate – Presented by Rahul Shah, M.D., vice president, chief quality and safety officer; Evan Hochberg, R.N., patient safety consultant; and Kathryn Jacobsen, R.N., director of patient safety: Psychological safety around event reporting is a crucial element of safety culture and the ability to voice concerns without reprisal leads to the ideal safe environment.
