Children’s National in Washington, D.C., is the nation’s No. 6 children’s hospital and, for the third year in a row, its neonatology program is No.1 among all children’s hospitals providing newborn intensive care, according to the U.S. News Best Children’s Hospitals annual rankings for 2019-20.
This is also the third year in a row that Children’s National has been in the top 10 of these national rankings. It is the ninth straight year it has ranked in all 10 specialty services, with five specialty service areas ranked among the top 10.
“I’m proud that our rankings continue to cement our standing as among the best children’s hospitals in the nation,” says Kurt Newman, M.D., President and CEO for Children’s National. “In addition to these service lines, today’s recognition honors countless specialists and support staff who provide unparalleled, multidisciplinary patient care. Quality care is a function of every team member performing their role well, so I credit every member of the Children’s National team for this continued high performance.”
The annual rankings recognize the nation’s top 50 pediatric facilities based on a scoring system developed by U.S. News. The top 10 scorers are awarded a distinction called the Honor Roll.
“The top 10 pediatric centers on this year’s Best Children’s Hospitals Honor Roll deliver outstanding care across a range of specialties and deserve to be nationally recognized,” says Ben Harder, chief of health analysis at U.S. News. “According to our analysis, these Honor Roll hospitals provide state-of-the-art medical expertise to children with rare or complex conditions. Their rankings reflect U.S. News’ assessment of their commitment to providing high-quality, compassionate care to young patients and their families day in and day out.”
The bulk of the score for each specialty is based on quality and outcomes data. The process also includes a survey of relevant specialists across the country, who are asked to list hospitals they believe provide the best care for patients with challenging conditions.
Below are links to the five specialty services that U.S. News ranked in the top 10 nationally:
- Neonatology (No. 1), led by Division Chief Billie Lou Short, M.D.
- Neurology and Neurosurgery (No. 5), led by Division Chiefs Roger J. Packer, M.D., and Robert F. Keating, M.D.
- Nephrology (No. 6), led by Division Chief Marva Moxey-Mims, M.D., FASN
- Cancer (No. 9), led by Division Chief Jeffrey S. Dome, M.D., Ph.D., and
- Pulmonology and lung surgery (No.9), led by Division Chief Anastassios Koumbourlis, M.D., MPH
Allopregnanolone (ALLO), a hormone made by the placenta late in pregnancy, is such a potent neurosteroid that disrupting its steady supply to the developing fetus can leave it vulnerable to brain injuries associated with autism spectrum disorder (ASD), according to Children’s research presented during the Pediatric Academic Societies 2019 Annual Meeting.
In order to more effectively treat vulnerable babies, the Children’s research team first had to tease out what goes wrong in the careful choreography that is pregnancy. According to the Centers for Disease Control and Prevention, about 1 in 10 babies is born preterm, before 37 weeks of gestation. Premature birth is a major risk factor for ASD.
The placenta is an essential and understudied organ that is shared by the developing fetus and the pregnant mother, delivering oxygen, glucose and nutrients and ferrying out waste products. The placenta also delivers ALLO, a progesterone derivative, needed to ready the developing fetal brain for life outside the womb.
ALLO ramps up late in gestation. When babies are born prematurely, their supply of ALLO stops abruptly. That occurs at the same time the cerebellum – a brain region essential for motor coordination, posture, balance and social cognition– typically undergoes a dramatic growth spurt.
“Our experimental model demonstrates that losing placental ALLO alters cerebellar development, including white matter development,” says Anna Penn, M.D., Ph.D., a neonatologist in the divisions of Neonatology and Fetal Medicine, and a developmental neuroscientist at Children’s National. “Cerebellar white matter development occurs primarily after babies are born, so connecting a change in placental function during pregnancy with lingering impacts on later brain development is a particularly striking result.”
The research team created a novel experimental model in which the gene encoding the enzyme responsible for producing ALLO is deleted in the placenta. They compared these preclinical models with a control group and performed whole brain imaging and RNAseq gene expression analyses for both groups.
“We saw long-term cerebellar white matter alterations in male experimental models, and behavioral testing revealed social impairments and increased repetitive behaviors, two hallmark features of ASD,” says Claire-Marie Vacher, Ph.D., lead study author. “These male-specific outcomes parallel the increased risk of brain injury and ASD we see in human babies born prematurely.”
ALLO binds to specific GABA receptors, which control most inhibitory signaling in the nervous system.
“Our findings provide a new way to frame poor placental function: Subtle but significant changes in utero may set in motion neurodevelopmental disorders that children experience later in life,” adds Dr. Penn, the study’s senior author. “Future directions for our research could include identifying new targets in the placenta or brain that could be amenable to hormone supplementation, opening the potential for earlier treatment for high-risk fetuses.”

Claire-Marie Vacher, Ph.D., lead author; Jackie Salzbank, co-author; Helene Lacaille, co-author; Dana Bakalar, co-author; Jiaqi O’Reilly, co-author; and Anna Penn, M.D., Ph.D., a neonatologist in the divisions of Neonatology and Fetal Medicine, developmental neuroscientist and senior study author.
People joke that Billie Lou Short, M.D., chief of Children’s Division of Neonatology, invented extracorporeal membrane oxygenation, known as ECMO for short. While Dr. Short did not invent ECMO, under her leadership Children’s National was the first pediatric hospital to use it. And over decades Children’s staff have perfected its use to save the lives of tiny, vulnerable newborns by temporarily taking over for their struggling hearts and lungs. For two consecutive years, Children’s neonatal intensive care unit has been named the nation’s No. 1 for newborns by U.S. News & World Report. “Despite all of these accomplishments, Dr. Short’s best legacy is what she has done as a mentor to countless trainees, nurses and faculty she’s touched during their careers. She touches every type of clinical staff member who has come through our neonatal intensive care unit,” says An Massaro, M.D., director of residency research.
For these achievements, Dr. Short received the Ninth Annual Mentorship Award in Clinical Science.
Anna Penn, M.D., Ph.D., has provided new insights into the central role that the placental hormone allopregnanolone plays in orderly fetal brain development, and her research team has created novel experimental models that mimic some of the brain injuries often seen in very preterm babies – an essential step that informs future neuroprotective strategies. Dr. Penn, a clinical neonatologist and developmental neuroscientist, “has been a primary adviser for 40 mentees throughout their careers and embodies Children’s core values of Compassion, Commitment and Connection,” says Claire-Marie Vacher, Ph.D.
For these achievements, Dr. Penn was selected to receive the Ninth Annual Mentorship Award in Basic and Translational Science.
The mentorship awards for Drs. Short and Penn were among dozens of honors given in conjunction with “Frontiers in Innovation,” the Ninth Annual Research and Education Week (REW) at Children’s National. In addition to seven keynote lectures, more than 350 posters were submitted from researchers – from high-school students to full-time faculty – about basic and translational science, clinical research, community-based research, education, training and quality improvement; five poster presenters were showcased via Facebook Live events hosted by Children’s Hospital Foundation.

The human brain is the body’s operating system. Imagine if rogue code worked its way into its hardware and software, delaying some processes, disrupting others, wreaking general havoc.
Neurodevelopmental disorders are like that errant code. They can occur early in life and impact brain development for the rest of the person’s life. Not only can fundamental brain development go awry, processes that refine the brain also can become abnormal, creating a double neural hit. Adding to those complications, children with neurodevelopmental disorders like autism spectrum disorder (ASD) and Fragile X syndrome often contend with multiple, overlapping cognitive impairments and learning disabilities.
The multiple layers of complexities for these disorders can make developing effective medical treatments particularly challenging, says Vittorio Gallo, Ph.D., Chief Research Officer at Children’s National Health System and recipient of a coveted Senator Jacob Javits Award in the Neurosciences.
During the Feb. 16, 2019, “Neurodevelopmental Disorders: Developing Medical Treatments” symposium, Gallo will guide esteemed panelists in a timely conversation about progress made so far and challenges that lie ahead during the AAAS Annual Meeting in Washington, the world’s largest general scientific gathering.
“This is a very important symposium; we’re going to put all of the open questions on the table,” says Gallo. “We’re going to present a snapshot of where the field is right now: We’ve made incredible advances in developmental neuroscience, neonatology, neurology, diagnostic imaging and other related fields. The essential building blocks are in place. Where are we now in developing therapeutics for these complex disorders?”
For select disorders, many genes have been identified, and each new gene has the potential to become a target for improved therapies. However, for other neurodevelopmental disorders, like ASD, an array of new genes continue to be discovered, leaving an unfinished picture of which genetic networks are of most importance.
Gallo says the assembled experts also plan to explore major research questions that remain unanswered as well as how to learn from past experiences to make future studies more powerful and insightful.
“One topic up for discussion will be new preclinical models that have the potential to help in identifying specific mechanisms that cause these disorders. A combination of genetic, biological, psychosocial and environmental risk factors are being combined in these preclinical models,” Gallo says.
“Our studies of the future need to move beyond describing and observing in order to transform into studies that establish causality between the aberrant developmental processes and these constellations of neurodevelopmental disorders.”
In October 2018, Children’s National hosted 20 neonatologists from 15 hospitals in China for a 10 day Quality Improvement Leadership Training Course focused on quality improvement principles and methodology. The course also featured presentations on hospital-wide quality improvement work and included speakers from the Quality & Safety Department, Nursing Quality, and the Neonatal Intensive Care Unit (NICU). The Performance Improvement team worked with the attendees on their own projects, such as reducing antibiotic use and increasing family-centered care in the NICU. The attendees then presented at the end of the course to their colleagues, as well as to five hospital presidents visiting from China.
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.

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.
“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.
The major neurotransmitters gamma-aminobutyric acid (GABA) and glutamate are pivotal to fetal and newborn brain development and influence evolution of brain injury and repair following preterm birth. Magnetic resonance spectroscopy (MRS) enables in vivo measurement of brain metabolites. However, GABA and glutamate are found in the developing brain in low concentrations, and their weak signal can be swamped by the stronger signal of more dominant metabolites.
A Children’s research team reports findings from a pilot study utilizing an innovative technique of MRS to reliably measure in vivo GABA in the developing preterm brain. The groundbreaking research done by the team that includes Principal Investigator Sudeepta K. Basu, M.D., neonatology attending at Children’s National Health System, is very unique and original since there are no existing data of in vivo GABA concentrations in the developing cerebellum. Under the mentorship of Catherine Limperopoulos, Ph.D., director of Children’s Developing Brain Research Laboratory, the team of multi-disciplinary specialists is pursuing cutting-edge technologies in advanced MRI neuroimaging to explore brain development and injury in preterm infants.
The research, presented at the Eastern Society for Pediatric Research (ESPR) annual meeting by Dr. Basu, was honored with the “2018 Meritorious Poster Award.” The research titled “Distinct temporal trends of GABA and glutamate in the cerebellum and frontal cortex of preterm infants” reports, for the first time, positive temporal trends in the specific regions of the developing brain intricately involved in cognitive and motor functions. This work lays the foundation for developing novel ways to diagnose, monitor and investigative brain protective therapies for vulnerable prematurely born infants.
The Children’s team performed non-sedated MRS in 44 preterm infants whose mean gestational age at birth was 26.5 weeks, placing voxels at the middle of the cerebellum and the right frontal cortex. GABA and GIx (glutamate combined with glutamine) were positively correlated with post-menstrual age in the frontal cortex, but not the cerebellum. At the ESPR meeting, the team also presented for the first time that caffeine, a neuroprotective agent in preemies, leads to increased in vivo GABA concentration in the developing frontal cortex.
“Open questions include whether these findings reflect varying paces of maturation and vulnerability to injury among specific regions of the brain. Also, the relationship between clinical factors and medication exposure and changes in the concentration of these neurotransmitters may guide brain protective therapies in future,” Dr. Basu says. “A more complete understanding of the diagnostic and prognostic importance of GABA and glutamate in the preterm brain will help us to direct treatment strategies for the most vulnerable preterm infants at risk of brain injury.”
Children’s senior fellows from Division of Neonatology made four platform presentations during the ESPR conference:
- “Caffeine increases GABA/Cr ratio in frontal cortex of preterm infants on spectroscopy.” Aditi Gupta; Sudeepta K. Basu, M.D.; Mariam Said, M.D.; Subechhya Pradhan, Linda White; Kushal Kapse; Jonathan Murnick, M.D., Ph.D.; Taeun Chang, M.D.; and Catherine Limperopoulos, Ph.D.

A team of researchers has found that quantitative magnetic resonance imaging (MRI) can identify pregnancies where placental dysfunction results in fetal growth restriction (FGR), creating the possibility for earlier FGR detection and intervention to augment placental function and thus minimize harm to the fetal brain.
The study, published online in the Journal of Perinatology, reports for the first time that in vivo placental volume is tied to global and regional fetal brain volumes.
Placental insufficiency is a known risk factor for impaired fetal growth and neurodevelopment. It may cause the fetus to receive inadequate oxygen and nutrients, making it difficult to grow and thrive. The earlier placental insufficiency occurs in a pregnancy, the more serious it can be. But detecting a failing placenta before the fetus is harmed has been difficult.
One additional challenge is that a fetus may be small because the placenta is not providing adequate nourishment. Or the fetus simply may be genetically predisposed to be smaller. Being able to tell the difference early can have a lifelong impact on a baby. Infants affected by FGR can experience behavioral problems, learning difficulties, memory and attention deficits, and psychiatric issues as the child grows into adolescence and adulthood.
“Our study proved that MRI can more accurately determine which pregnancies are at greater risk for impaired fetal health or compromised placenta function,” says Nickie Andescavage, M.D., the study’s lead author and a specialist in neonatology and neonatal neurology and neonatal critical care at Children’s National Health System. “The earlier we can identify these pregnancies, the more thoughtful we can be in managing care.”
Dr. Andescavage’s research focus has been how fetal growth affects labor, delivery and postnatal complications.
“We don’t have a good understanding of why FGR happens, but we do know it’s hard to identify during pregnancy because often there are no signs,” says Dr. Andescavage. “Even when detected, it’s hard to follow. But if we’re aware of it, we can better address important questions, like when to deliver an at-risk fetus.”
In the study, the team measured placental and fetal brain growth in healthy, uncomplicated pregnancies and in pregnancies complicated by FGR. A total of 114 women participated, undergoing ultrasound, Doppler ultrasound and MRI imaging to measure placental volume and fetal brain volume.
An ultrasound test is often what detects FGR, but the measurements generated by ultrasound can be non-specific. In addition, reproducibility issues with 3D sonography limit its use as a standalone tool for placental assessment. Once FGR is detected via ultrasound, this study showed that complementary MRI provides more accurate structural measures of the fetal brain, as well as more detail and insight into placental growth and function.
“Our team has studied FGR for a few years, using imaging to see that’s happening with the fetus in real time,” says Dr. Andescavage. “The relationship of placental volume and fetal brain development had not been previously studied in utero.”
In pregnancies complicated by FGR, MRI showed markedly decreased placental and brain volumes. The team observed significantly smaller placental, total brain, cerebral and cerebellar volumes in these cases than in the healthy controls. The relationship between increasing placental volume and increasing total brain volume was similar in FGR and in normal pregnancies. However, the study authors write “the overall volumes were smaller and thus shifted downward in pregnancies with FGR.”
In addition, FGR-complicated pregnancies that also showed abnormalities in Doppler ultrasound imaging had even smaller placental, cerebral and cerebellar volumes than pregnancies complicated by FGR that did not have aberrations in Doppler imaging.
Since this study showed that quantitative fetal MRI can accurately detect decreased placental and brain volumes when FGR is present, Dr. Andescavage believes this imaging technique may give doctors important new insights into the timing and possibly the mechanisms of brain injury in FGR. “Different pathways can lead to FGR. With this assessment strategy, we could potentially elucidate those,” she adds.
Using quantitative MRI to identify early deviations from normal growth may create opportunities for future interventions to protect the developing fetal brain. New treatments on the horizon promise to address placental health. MRI could be used to investigate these potential therapies in utero. When those therapies become available, it could allow doctors to monitor treatment effects in utero.

Maureen Maurano, NICU Nurse Manager at Children’s National Health System, was honored as the winner of the 2017 Richard Hader Visionary Leader Award at the Nursing Management Congress 2017 held October 2-6, 2017 in Las Vegas, Nevada. The annual award recognizes excellence in nursing leadership and awards a nurse leader who views nursing as both an art and a science by promoting caring and competence as the link between science and humanity.
The winner of the award is nominated by a colleague and is entered into the competition after the Nursing Management journal’s editorial board has received a 2,000 word manuscript detailing the nominee’s accomplishment in the planning, development, implementation and evaluation of a sustainable change in the work environment or clinical practice that has resulted in a positive outcome. The editorial board selects the winner based on the manuscript’s readability, originality, and evidence of credibility. The winning manuscript will be featured in the January 2018 issue of Nursing Management.
“I am truly honored to have accepted this Visionary Leadership Award, however, this could not have been achieved without our amazing leadership and nursing team,” says Maurano. “It is truly a team effort that empowers our success on a daily basis in providing the most innovative and world-class care for our patients at Children’s.”
Vice President of Nursing and Chief Nursing Officer, Linda Talley says, “Maureen is an outstanding nurse leader who exemplifies our core values – commitment, compassion and connection – through her engagement of others, creating a positive work environment and driving change that has a positive influence on the professional practice of nursing. We are very proud of her and the recognition she has so deservedly earned.”
With a crowd of over 2,000 medical professionals, Maurano accepted her award as a leader of excellence representing the U.S. News and World Report #1 NICU for babies. Congratulations again Maureen for receiving this great honor!
American health care is some of the most expensive in the world. To help make it more affordable, numerous efforts in all areas of medicine – from cancer care to primary care to specialized pediatrics – are focused on finding ways to improve quality and patient safety while also cutting costs.
About half a million babies born in the United States – or 10 percent to 15 percent of U.S. births – end up in the neonatal intensive care unit (NICU), most due to prematurity and very low birth weights. These vulnerable babies often need respiratory support in the form of a ventilator, which supplies oxygen to their lungs with a plastic endotracheal tube (ETT).
The typical care for these infants often involves frequent X-rays to verify the proper position of the tube. However, the American Academy of Pediatrics has counseled health care providers that ordering a daily chest X-ray simply to verify positioning of the ETT ratchets up costs without improving patient safety.
A quality-improvement initiative by Children’s National Health System’s NICU finds that these chest X-rays can be performed just twice weekly, lessening the chances of a breathing tube popping out accidentally, reducing infants’ exposure to radiation and saving an estimated $1.6 million per year.
“The new Children’s National protocol reduced the rate of chest X-rays per patient day without increasing the rate of unintended extubations,” says Michelande Ridoré, M.S., program lead in Children’s division of neonatology, who presented the research during the 2017 American Academy of Pediatrics (AAP) national conference. “That not only helps to improve patient safety – for newborns who are admitted to the NICU for longer periods, there is the additional benefit of providing significant savings to the health care system.”
Children’s NICU staff assessed how many chest X-rays were being performed per patient day before and after the protocol change, which applied to all intubated newborns in the NICU whose health condition was stable. Newborns had been undergoing a median of 0.45 chest X-rays per patient day. After the quality improvement project, that figure dropped to 0.23 chest X-rays per patient day.
When the project started in July 2015, the NICU’s monthly X-ray expenditure was $289,520. By the end of 2015, that monthly X-ray spend had fallen to $159,424 – resulting in nearly $1.6 million in annual savings.
The more restrictive strategy for ordering chest X-rays was a core component of a broader quality improvement effort aimed at lowering the number of unplanned extubations, which represent the fourth most common complication experienced by newborns in the nation’s NICUs.
“When you reduce the frequency of patients in the unit being moved, you decrease the chances of the breathing tube coming out accidentally,” Ridoré says. “By reducing unplanned extubations in the NICU, we can improve overall clinical outcomes, reduce length of stay, lower costs and improve patient satisfaction.”
When a breathing tube is accidentally dislodged, newborns can experience hypoxia (oxygen deficiency), abnormally high carbon dioxide levels in the blood, trauma to their airway, intraventricular hemorrhage (bleeding into the fluid-filled areas of the brain) and code events, among other adverse outcomes. What’s more, a patient with an unintended extubation can experience a nearly doubled hospital stay compared with the length of stay for newborns whose breathing tubes remain in their proper places. Each unplanned extubation can increase the cost of care by $36,000 per patient per admission.
To tackle this problem, Children’s National created the Stop Unintended Extubations “SUN” team. The team created a package of interventions for high-risk patients. Within one month, unintended extubations dropped from 1.18 events per 100 ventilator days to 0.59 events during the same time frame. And, within five months, that plummeted even further to 0.41 events per 100 ventilator days.
Their ultimate goal is to whittle that rate down even further to 0.3 events per 100 ventilator days, which has occurred sporadically. And the NICU notched up to 75 days between unintended extubations.
“Unintended extubation rates at Children’s National are lower than the median reported on various quality indices, but we know we can do more to enhance patient safety,” Ridoré says. ”Our SUN team will continue to address key drivers of this quality measure with the aim of consistently maintaining this rate at no more than 0.3 events per 100 ventilator days.”
