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.”

Children’s National emergency medicine specialists win best abstract

Lenore Jarvis, M.D., an Emergency Medicine Specialist at Children’s National Health System, won Best Abstract in the Section of Emergency Medicine at the American Academy of Pediatrics 2016 National Conference. Monika Goyal, MD, MSCE, also an Emergency Medicine Specialist at Children’s, is senior author of the study.

The abstract, titled Postpartum Depression Screening in a Pediatric ED, explored the topic through an investigation of the prevalence of postpartum depression positive screens, factors associated with them, and the frequency of screenings and the impact they have.

The research findings may help with future efforts to support mothers with infants who use the emergency department.

Treating injured adolescents at pediatric trauma centers associated with lower mortality

As children mature into adolescence, they also transition from being cared for by pediatric healthcare providers to being cared for by health professionals who primarily treat adults. Controversy remains about whether a primarily pediatric or adult treatment location is optimal to meet the needs of injured adolescents. For this reason, the cutoff age for triaging children to pediatric versus adult trauma hospitals varies in different settings. A research team led by Randall S. Burd, MD, PhD, Chief of the Children’s National Health System Division of Trauma and Burn Surgery, found that injured adolescents treated at pediatric trauma centers (PTCs) had a lower mortality rate than injured adolescents treated at adult trauma centers (ATCs) or mixed trauma centers (MTCs), facilities that treat both adults and children, even when controlling for differences in patients.Trauma is a leading cause of death and acquired disability among adolescents. To determine any potential association between the type of trauma center and mortality rates, the research team examined 29,613  records for patients aged 15 to 19 years old drawn from the 2010 National Trauma Data Bank.“Trauma centers dedicated to the treatment of pediatric patients see a different adolescent population than do ATCs and MTCs,” Dr. Burd and colleagues write in an article published June 27 by JAMA Pediatrics. “After controlling for these differences, we observed that adolescent trauma patients have lower overall and in-hospital mortality when treated at PTCs.”

These findings, bolstered by additional research, have the potential to change the approach for triaging injured adolescents, says Dr. Burd, the paper’s senior author. The study findings suggest that commonly used age thresholds of 14 or 15 years might be safely adjusted higher.

Because the data were obtained from a large dataset, making that case will require closer examination – perhaps chart-by-chart analysis for each patient – to tease out nuances that differentiate care adolescents receive at different types of trauma hospitals, Dr. Burd says. “Are there differences in the process of care – or availability of specific resources – that account for the differences in outcome? Or, do the patients treated at each hospital type have differences in their injuries that we have not yet identified?”

Most adolescents (68.9 percent) included in the study were treated at an adult trauma center. In addition to being older, these youths were more likely to be severely injured and more frequently suffered severe injuries to the head, chest, and upper extremities. The most common traumatic injuries seen at adult centers resulted from children being passengers in motor vehicles (32.6 percent). Penetrating injuries from firearms (12 percent) and cutting or piercing (7.1 percent) were more common at adult centers.

Some 1,636 patients (5.5 percent) were treated at a pediatric trauma center, with many being transferred there from another hospital. Adolescents treated at pediatric trauma centers were more likely to be injured by a blunt rather than penetrating mechanism. The most common injuries seen at pediatric centers were injuries from a fall (25.9 percent) or injuries that resulted from being struck (26.1 percent).

“Because adolescents straddle the gap between pediatric and adult medicine, identifying differences in care among PTCs, ATCs, and MTCs will help determine the most appropriate triage strategies or identify practice strategies that can optimize the outcome for patients in this age group,” the authors conclude.

Association Seen Between Trauma Center Type and Mortality Risk for Injured Youths

What’s Known
Trauma is the leading cause of death among children and young adults in the United States, but controversy remains about which treatment location is optimal to meet the needs of injured adolescent patients. Pediatric trauma centers tailor care to children’s unique physiological,anatomical, and social needs. Yet, there are variations in the cutoff age used to triage children to either pediatric or adult trauma centers, with the usual decision to triage children to pediatric facilities if they are younger than 14 or 15 and to transport them to adult systems if they are older. A 2015 study found that injured children aged 18 or younger treated at pediatric trauma centers had lower in-hospital mortality.

What’s New
A team led by Children’s National Health System researchers examined 29,613 de-identified records for patients aged 15 to 19 years old drawn from the 2010 National Trauma Data Bank to determine associations between the type of trauma center and youths’ mortality rates. Some 68.9 percent of injured youths were treated at adult trauma centers (ATCs), while 25.6 percent were seen at mixed trauma centers (MTCs), and 5.5 percent at pediatric trauma centers (PTCs). Mortality was higher among youths treated at ATCs (3.2 percent) and MTCs (3.5 percent) than for adolescents seen at PTCs (0.4 percent), P < .001. The adjusted odds of mortality were higher at ATCs (4.19) and MTCs (6.68 ) compared with PTCs (0.76). While the research team saw differences in mortality between trauma center type, the study does not provide information about what may account for these differences.

Questions for Future Research

  • What is the best method to determine differences in treatment practices between trauma center types to better explain differences in the mortality rates of injured adolescents?
  • Which specific qualities are common to trauma centers that provide optimal outcomes to children, and can quality-improvement initiatives help to identify and replicate those attributes elsewhere?
