Keeping kids with asthma out of the hospital

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.

New method may facilitate childhood respiratory research

Gustavo Nino

“The use of CRC is a potentially powerful translational approach to shed light on the molecular mechanisms that control airway epithelial immune responses in infants and young children. This novel approach enables us to study the origins of respiratory disease and its chronic progression through childhood and beyond,” observes Gustavo Nino, M.D., a Children’s pulmonologist and study senior author.

A new method perfected by a team at Children’s National Health System may help expand research into pulmonary conditions experienced by infants and children, an understudied but clinically important age group. The study describing the new technique was published in the December 2017 print edition of Pediatric Allergy and Immunology.

Using conditionally reprogrammed cells (CRCs), a technique that enables indefinite proliferation of cells in the lab, the team was able to produce cell cultures that have a number of advantages over standard cultures and that may make it easier and more efficient to conduct research into pediatric respiratory immune responses.

The epithelial cells that line human airways are crucial in controlling immune responses to viruses, allergens and other environmental factors. The function and dysfunction of these airway epithelial cells (AECs) play a key role in asthma, cystic fibrosis and other pulmonary conditions, many of which begin in early life.

To generate enough of these cells for research, scientists culture AECs from primary nasal and bronchial cell samples. Cells derived from adults have fueled research leading to new therapies and the discovery of key biomarkers. But little comparable research has been conducted in infants. Airway sampling in premature infants has not been reported, likely to due to airway size limitations and underlying comorbidities. Similarly, sampling in infants is limited by the need for bronchoscopy and sedation.

“A major barrier has been the lack of a good system to culture epithelial cells, since airway sampling in infants and children is a challenge,” says co-lead author, Geovanny F. Perez, M.D., co-director of Children’s Severe Bronchopulmonary Dysplasia Program. “We needed a better way to culture cells in this age group.”

While primary AECs do not survive long in the lab, that hurdle was recently overcome by a process that generates CRCs from the primary AECs of adults, making it possible to quickly generate cell cultures from specimens.

In this study, the Children’s team adapted that approach, producing CRCs from primary AECs of neonates and infants. The CRC induction successfully enabled AEC cultures from infants born prematurely and from bronchial specimens of young children.

“A major barrier has been the lack of a good system to culture epithelial cells, since airway sampling in infants and children is a challenge,” says co-lead author, Geovanny F. Perez, M.D., co-director of Children’s Severe Bronchopulmonary Dysplasia Program. “We needed a better way to culture cells in this age group.”

“We found that the CRCs have longer cell life and greater proliferation ability than standard cultures of epithelial cells. They preserved their original characteristics even after multiple experiments. And, they presented an innate immune response similar to that seen in primary human epithelial cells during viral respiratory responses in children,” says Dr. Perez.

“The use of CRC is a potentially powerful translational approach to shed light on the molecular mechanisms that control airway epithelial immune responses in infants and young children. This novel approach enables us to study the origins of respiratory disease and its chronic progression through childhood and beyond,” observes Gustavo Nino, M.D., a Children’s pulmonologist and study senior author.

The authors note that further studies are needed to define more precisely the differences and similarities in the immune responses of CRC and non-CRC derived from primary AEC. However, they conclude that CRC represents a new, effective method to study AEC innate immune responses in infants.

X-linked genes help explain why boys of all ages face higher respiratory risk

Gustavo Nino

“It’s clear as we round in the neonatal intensive care unit that baby boys remain hospitalized longer than girls and that respiratory ailments are quite common. Our work provides new insights about gender differences in airway disease risk that are pre-determined by genetics,” says Gustavo Nino, M.D.

Human airways already demonstrate gender-based differences in DNA methylation signatures at birth, providing an early hint of which infants may be predisposed to develop respiratory disorders like asthma later in life, a research team reports in a paper published online April 3, 2018, in Scientific Reports.

It’s clear that boys and young men are more likely to develop neonatal respiratory distress syndrome, bronchopulmonary dysplasia, viral bronchiolitis, pneumonia, croup and childhood asthma. Unlike boys, girls have an additional copy of the X chromosome, which is enriched with immune-related genes, some of which play key roles in the development of respiratory conditions. Methylation prevents excessive gene activity in X-linked genes, however much remains unknown about how this process influences infants’ risk of developing airway diseases.

A multi-institution research team that includes Children’s National Health System attempted to characterize gender-based epigenomic signatures in the human airway early in children’s lives with a special attention to defining DNA methylation patterns of the X chromosome.

“It’s clear as we round in the neonatal intensive care unit that baby boys remain hospitalized longer than girls and that respiratory ailments are quite common. Our work provides new insights about gender differences in airway disease risk that are pre-determined by genetics,” says Gustavo Nino, M.D., a Children’s pulmonologist and the study’s senior author.

“Characterizing early airway methylation signatures holds the promise of clarifying the nature of gender-based disparities in respiratory disorders and could usher in more personalized diagnostic and therapeutic approaches.”

The research team enrolled 12 newborns and infants in the study and obtained their nasal wash samples. Six of the infants were born preterm, and six were born full term. The researchers developed a robust gender classification algorithm to generate DNA methylation signals. The machine learning algorithm identified X-linked genes with significant differences in methylation patterns in boys, compared with girls.

As a comparison group, they retrieved pediatric nasal airway epithelial cultures from a study that looked at genomic DNA methylation patterns and gene expression in 36 children with persistent atopic asthma compared with 36 heathy children.

The team went on to classify X-linked genes that had significant gender-based X methylation and those genes whose X methylation was variable.

“These results confirm that the X chromosome contains crucial information about gender-related genetic differences in different airway tissues,” Dr. Nino says. “More detailed knowledge of the genetic basis for gender differences in the respiratory system may help to predict, prevent and treat respiratory disorders that can affect patients over their entire lifetimes.”

Discharge strategies to prevent asthma readmissions

“Improving how we care for children who are hospitalized with asthma includes preparing them for a successful return home with the best tools to manage their illness and prevent a future hospital visit,” says Kavita Parikh, M.D., M.S.H.S.

Readmission rates at three months for kids hospitalized for acute asthma dropped when families received comprehensive education prior to discharge, the only single component of discharge bundles that was strongly associated with lowered readmissions, finds a multicenter retrospective cohort study published online Feb. 1, 2018, in The Journal of Pediatrics.

According to the Centers for Disease Control and Prevention, asthma is the most common chronic lung disease of childhood, affecting roughly 6 million U.S. children. Hospitalization for asthma accounts for $1.5 billion in annual hospital charges and represents almost one-third of childhood asthma costs.

Children who are hospitalized for asthma have a roughly 20 percent chance of returning to the hospital in the next year, and individual hospital readmission rates can range from 5.7 percent to 9.1 percent at three months, writes the study team. While the National Institutes of Health (NIH) has published evidence-based guidelines for discharge planning, there is no single, standardized asthma discharge process used across all pediatric hospitals in the U.S. that impacts 30-day readmission rates.

“Improving how we care for children who are hospitalized with asthma includes preparing them for a successful return home with the best tools to manage their illness and prevent a future hospital visit,” says Kavita Parikh, M.D., M.S.H.S., an associate professor of pediatrics at Children’s National Health System and lead study author. “Our study underscores the importance of increasing the intensity of select discharge components. For example, ensuring that children hospitalized for asthma receive asthma medication at discharge along with comprehensive education and environmental mitigation may reduce asthma readmissions.”

The study team analyzed records from a national sample of tertiary care children’s hospitals, looking at hospitalizations of 5- to 17-year-olds for acute asthma exacerbation during the 2015 calendar year. They characterized how frequently hospitals used 13 separate asthma discharge components by distributing an electronic survey to quality leaders. Forty-five of 49 hospitals (92 percent) completed the survey.

The 45 hospitals recorded a median of 349 asthma discharges per year and had a median adjusted readmission rate of 2.6 percent at 30 days and a 6.6 percent median adjusted readmission rate at three months. The most commonly used discharge components employed for children with asthma were having a dedicated person providing education (76 percent), providing a spacer at discharge (67 percent) and communicating with a primary medical doctor (58 percent).

Discharge components that were trending toward reduced readmission rates at three months include:

  • Comprehensive asthma education, including having dedicated asthma educators
  • Medications and devices provided to patients at discharge, such as spacers, beta-agonists, controller medication and oral steroids
  • Communication and scheduled appointments with a primary medical doctor
  • Post-discharge activities, including home visits and referrals for environmental mitigation programs.

“In addition to being aligned with NIH asthma recommendations, connecting the family with a primary care provider after discharge helps to improve patients’ timely access to care if symptoms recur when they return home,” Dr. Parikh adds. “Bundling these discharge components may offer multiple opportunities to educate patients and families and to employ a range of communication styles such as didactic, visual and interactive.”

Human Rhinovirus

When a common cold may trigger early supportive care

Human Rhinovirus

A new study led by Children’s National Health System shows that in infants who were born severely premature, human rhinovirus infections appear to trigger airway hyper-reactivity, which leads to wheezing, hyperinflation and more severe respiratory disease.

Human rhinovirus (HRV), the culprit behind most colds, is the leading cause of hospitalization for premature babies. However, in very preterm children, exactly how HRV causes severe respiratory disease – and which patients may need more intensive observation and treatment – is less well understood.

A new study led by Children’s National Health System research-clinicians showed in children who were born severely premature, HRV infections seem to trigger an airway hyper-reactivity (AHR) type of disease, which leads to wheezing and air-trapping (hyperinflation) and more severe respiratory disease. This, in turn, increases the risk for hospitalization.

The study, published online Oct. 21, 2017 in Pediatrics and Neonatology, found that other signs of respiratory distress, such as low arterial blood oxygen or rapid shallow breathing, were no more common in severely premature children (less than 32 weeks of gestational age) than in kids born preterm or full-term. The findings have implications for administering supportive care sooner or more intensively for severely premature children than for other infants.

“When it comes to how they respond to such infections, severely premature children are quite different,” says Geovanny Perez, M.D., a specialist in pulmonary medicine at Children’s National and lead study author. “We’ve known they are more susceptible to human rhinovirus infection and have more severe disease. However, our study findings suggest that severely premature kids have an ‘asthma’ type of clinical picture and perhaps should be treated differently.”

The study team sought to identify clinical phenotypes of HRV infections in young children hospitalized for such infections. The team theorized that severely premature babies would respond differently to these infections and that their response might resemble symptoms experienced by patients with asthma.

“For a number of years, our team has studied responses to viruses and prematurity, especially HRV and asthma,” Dr. Perez says. “We know that premature babies have an immune response to HRV from the epithelial cells, similar to that seen in older patients with asthma. But we wanted to address a gap in the research to better understand which children may need closer monitoring and more supportive care during their first HRV infection.”

Geovanny Perez

“When it comes to how they respond to such infections, severely premature children are quite different,” says Geovanny Perez, M.D. “We’ve known they are more susceptible to human rhinovirus infection and have more severe disease. However, our study findings suggest that severely premature kids have an ‘asthma’ type of clinical picture and perhaps should be treated differently.”

In a retrospective cross-sectional analysis, the study looked at 205 children aged 3 years or younger who were hospitalized at Children’s National in 2014 with confirmed HRV infections. Of these, 71 percent were born full-term (more than 37 gestational weeks), 10 percent were preterm (32 to 37 gestational weeks) and 19 percent were severely premature (less than 32 gestational weeks).

Dr. Perez and his team developed a special respiratory distress scoring system based on physical findings in the children’s electronic medical records to assess the degree of lower-airway obstruction or AHR (as occurs in asthma) and of parenchymal lung disease. The physical findings included:

  • Wheezing;
  • Subcostal retraction (a sign of air-trapping/hyperinflation of the lungs), as can occur in pneumonia;
  • Reduced oxygen levels (hypoxemia); and
  • Increased respiratory rate (tachypnea).

The research team assigned each case an overall score. The severely premature children had worse overall scores – and significantly worse scores for AHR and hyperinflated lungs relative to children born late preterm or full-term.

“What surprised us, though, in this study was that the phenotypical characterization using individual parameters for parenchymal lung disease, such as hypoxemia or tachypnea, were not different in severe preterm children and preterm or full term,” says Dr. Perez. “On the other hand, our study found that severely preterm children had a lower airway obstruction phenotype associated with retractions and wheezing. Moreover there was a ‘dose effect’ of prematurity: Children who were born more premature had a higher risk of wheezing and retractions.”

Among the implications of this study, Dr. Perez sees the potential to use phenotypical (clinical markers, such as retractions and wheezing) and biological biomarkers to better personalize patients’ treatments. Dr. Perez and his team have identified biological biomarkers in nasal secretions of children with rhinovirus infection that they plan to combine with clinical biomarkers to identify which patients with viral infections will benefit from early supportive care, chronic treatments or long-term monitoring.

Dr. Perez says further research in this area should pursue a number of paths, including:

  • A longitudinal study to elucidate which children will benefit from asthma-like treatment, such as bronchodilators or corticosteroids;
  • A study of biomarkers, including microRNAs and other inflammatory molecules; or
  • Alternatively, a longitudinal study exploring the mechanism by which wheezing develops, perhaps looking at first and subsequent rhinovirus infections in babies born at different gestational ages.
asthma medication delivery

School’s in for asthma medication adherence

asthma medication delivery

A research team from Children’s National tried to reduce missed doses of daily medications, improve asthma control and tamp down on schoolchildren’s asthma attacks by outsourcing morning delivery of inhaled corticosteroids to the school nurse.

Doctors and researchers have long known that the level of stress patients experience is inversely linked to how adherent they are with taking medications: The higher the stress, the less likely patients are to take doses of their medication correctly, on time or at all. For families of school-aged children, there are few times more stressful than mornings, when parents or caregivers need to get kids ready for their school day, pack everything they need and get them out the door on time.

These stressful mornings, says Stephen J. Teach, M.D., M.P.H., chair of the Department of Pediatrics at Children’s National Health System, can spell danger for children with persistent asthma. This chronic condition is typically treated with nightly and morning doses of inhaled corticosteroids (ICS), medications that decrease lung inflammation to prevent asthma attacks. When children miss a morning dose because their families are too busy, their asthma symptoms can exacerbate, causing them to miss school, be unable to participate in activities like sports or lose sleep at night.

But Dr. Teach and colleagues had a simple idea to bypass the morning struggle for many families: Instead of trying to fit delivery of ICS into an already packed schedule, why not outsource it to the school nurse?

“We thought that if we could have those morning doses administered by these medically trained individuals with great technique and regularity, then maybe we would see some improved outcomes in kids,” Dr. Teach says. “And we did, in a striking way.”

Dr. Teach and colleagues recruited 46 children to participate in a pilot study, published online June 8, 2017 in the Journal of Asthma. To be eligible, these participants had to be in grades kindergarten through eighth in the Washington, D.C. public school system and on Medicaid, demonstrating the type of financial need that can add to the cumulative stress a family already faces. The children were scattered across 18 schools.

“We thought that if we could have those morning doses administered by these medically trained individuals with great technique and regularity, then maybe we would see some improved outcomes in kids,” Dr. Teach says. “And we did, in a striking way.”

Twenty-one of these participants received morning doses of ICS (the intervention group), which the researchers provided to school nurses along with an asthma action plan. The rest (the control group) remained on their prescribed morning and evening doses at home.

After 60 days, the researchers followed up with schools and families. Through electronic records kept by each school, the researchers found that the intervention group received more than 90 percent of their prescribed morning doses—about the same number reported by parents of the control group. However, the two groups demonstrated impressive differences in quality-of-life measures:

  • While about 24 percent of the intervention group missed one or fewer days of school due to asthma during the 60-day trial, about 44 percent of the control group did.
  • About 43 percent of the intervention group reported functional limitations due to their asthma, compared with 74 percent of the control group.
  • The intervention group reported only 1.7 nights with asthma-related sleep loss in the previous two weeks, compared with 4.1 nights in the control group.
  • Additionally, only about one-quarter of the intervention group required adjustments in family life to accommodate their asthma, compared with more than one-half of the control group.

The reasons for these differences aren’t clear, says Dr. Teach. But he and colleagues suggest that they might be due to over-reporting of how many doses were delivered at home in the control group or improper administration of these drugs at home.

Regardless, he says, the results show that this type of school-based intervention was not only feasible for children, school nurses and families, but also led to numerous positive health outcomes for the participants who received it. Based on the results of this study, Dr. Teach and colleagues have started to prescribe school-based administration of morning ICS doses to families interested in receiving them as a new standard of care.

“These data, combined with data from similar studies at other institutions, suggest that school-based therapy is increasingly becoming a very real and proven option for clinicians and families when adherence is a struggle,” he says.

A successful patient-centered asthma study

Stephen Teach does an asthma exam

A study by Stephen Teach, M.D., M.P.H., shows that extensively engaging stakeholders such as parents, families and local service providers in study design can transform a planned research project into a more patient-centered study.

For hundreds of years, scientific and medical research has followed a process that practically all grade-school children learn as the scientific method: Scientists make observations that lead to a question. After developing a hypothesis, the researchers and colleagues — usually other scientists in the same field — test it by gathering data from experiments, making more observations or searching through the existing literature. Once they have an answer, the researchers often publish it in a scientific journal, which can generate new questions among peer scientists and starts the cycle all over again.

While most research is meant to benefit humankind as a whole, non-scientists and people who aren’t research subjects usually aren’t involved much in the process itself. That can be a serious omission, particularly for medical research, says Stephen J. Teach, M.D., M.P.H., chair of the Department of Pediatrics at Children’s National Health System, and Deborah Quint Shelef, M.P.H., C.C.R.P., AE-C., program director at IMPACT DC, a program at Children’s National Health System that helps patients effectively manage asthma.

“Our patients might view research a little differently than we do. They don’t just want general contributions to knowledge, but specific contributions that people can actually use,” Shelef says. “One of our main goals is to have useful research models that can translate into changes that really improve patient care. It’s hard to make this happen without asking people who are affected most what would address their needs.”

That’s why Shelef and Dr. Teach’s most recent study, featured on the cover of the December 2016 issue of The Journal of Allergy and Clinical Immunology, shifts the research paradigm from a scientist-centered model to what they call a stakeholder-centered approach. Rather than develop the study solely with fellow researchers, the research team led by Children’s National relied heavily on guidance from people who would be most impacted by the results.

The study focused on whether an intervention that reduced parental stress could improve asthma outcomes among low-income African American children. To help design their study, the research team looked to several different sources for advice: African American parents of children treated for asthma at Children’s National; local providers of social, medical, legal and educational services; and experts in psychosocial stress, medication adherence and conducting studies among at-risk youth with asthma.

The researchers gave themselves one year to consult multiple times with each stakeholder group before starting to enroll study subjects in May 2015. In the initial planning phases, the research team intended to focus their study on whether reducing parental stress would change how well children stuck to taking their asthma medications. However, that focus quickly changed, says Shelef. “Medication adherence just wasn’t a meaningful goal to most parents,” she explains. “To them, having more symptom-free days was a better gauge of how well an intervention was working for their children.”

The proposed intervention itself also transformed. Rather than focusing on problem-solving, cognitive-reframing and parenting skills — the researchers’ initial ideas — the final intervention would instead teach participants mindfulness, deep breathing, positive thinking, self-care and gratitude — as well as how to use these coping skills with their children. Rather than being staffed by social workers or psychologists, the stakeholders preferred people they felt they could relate to: Community wellness coaches with experience teaching yoga, meditation or other wellness activities in neighborhoods in which they lived.

Several other tweaks significantly changed the study from its early incarnation into the final version that the researchers are currently implementing, says Dr. Teach. “We ended up in a very different place from where we started based on this extensive process of stakeholder engagement,” he says.

Shelef notes that it’s not always feasible to involve stakeholders so heavily or to intensively plan a study for a year before it begins. Keeping all the advisers focused on the study at hand without radically changing the focus was a challenge, she says, and it was an “incredible scramble” in the end to translate all of their feedback into a cohesive product. However, having input from the people who could gain the most from the research results made it all worth it.

“The real benefit to this approach is the richness of the final product,” Shelef says. “Ultimately, this study will show a lot more than if we hadn’t put so much into it at the beginning.”

Improving asthma care at community emergency departments

Through partnerships with community health care facilities, children suffering from severe asthma attacks can receive the type of state-of-the-art care championed by Children’s National.

Asthma is an exceedingly common pediatric disease, affecting nearly 7 million children in the United States, particularly in urban areas. Asthma is responsible for more than 775,000 Emergency Department (EDs) visits each year. However, the vast majority of these visits are to community EDs closest to patients’ homes, rather than to medical centers that specialize in pediatric care.

This fact could potentially lead to big problems for small patients, says Theresa A. Walls, M.D., M.P.H., Director of Emergency Department Outreach at Children’s National Health System. Nearly 70 percent of EDs in the United States treat fewer than 14 children a day, leaving many without the requisite experience or resources critical to effectively treat pediatric patients. Research shows that children seen for asthma in general community EDs are less likely to receive corticosteroid medications systemically — an essential first-line therapy during an asthma attack per National Institutes of Health guidelines — compared with children seen at pediatric EDs. Additionally in these general EDs, children are also more likely to receive unnecessary testing and treatment.

“In our experience, the emergency care of children with asthma in our area mirrors what has been found in national studies: Children are not treated as aggressively in community EDs. If we partner with them and get them to treat asthma as aggressively as we do, it would be a great thing for pediatric patients.”

That’s why when a nurse educator from a local community hospital’s ED contacted them to try to improve pediatric asthma care, Dr. Walls and Children’s colleagues jumped at the opportunity. “They were motivated participants,” she says. “It was a great way to start a partnership.”

The team worked with the community hospital’s ED to implement a pediatric asthma care plan known as a “pathway,” similar to the one currently in place at Children’s National, to ensure that children in the throes of an asthma attack receive evidence-based care that significantly decreases their chances of hospital admission or transfer to a specialty center.

The treatment pathway includes elements such as assigning each patient an asthma score — a number ranging from 1 to 10 that characterizes the severity of the patient’s asthma attack. The treatment plan also includes providing corticosteroids as quickly as possible to more eligible patients.

Effectively implementing this plan requires the efforts of a multidisciplinary team of providers and experts. Beyond the physicians, nurses and respiratory therapists who care for patients directly, this includes pharmacists to ensure proper doses of medications are available in child-friendly liquid forms and information technology specialists to revamp the hospital’s electronic charting system, automatically requesting an asthma score or recommending appropriate medication orders.

To gauge whether mimicking Children’s asthma pathway made a significant difference at the community ED, Dr. Walls and colleagues launched a study that was published online December 8, 2016, in Pediatrics. Comparing data collected for 19 months after the new guidelines were put into place with data from 12 months prior, the researchers made some promising initial findings. Following the pathway implementation, 64 percent of children ages 2 to 17 who arrived at the community ED with asthma symptoms received an asthma score. About 76 percent of these patients with asthma received corticosteroids after the pathway was in place, compared with 60 percent of comparable patients prior to the switchover. The mean time to corticosteroid administration dropped by nearly half, falling from 196 to 105 minutes. Additionally, Dr. Walls says, 10 percent of patients required transfer to another hospital after pathway implementation, compared with 14 percent before — another significant drop.

Dr. Walls notes that there is significant room for improving these metrics and overall asthma care at community EDs. The research team hopes to continue working with the first community hospital and expand their partnership to form a network of other local hospitals. By working together in a large collaboration, she says, hospitals can share resources and knowledge while learning from each other’s successes and mistakes.

“The more we can deliver this state-of-the-art care to the community,” she says, “the better, because that’s where most kids go.”
