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

Children’s National rose in rankings to become the nation’s Top 5 children’s hospital according to the 2018-19 Best Children’s Hospitals Honor Roll released June 26, 2018, by U.S. News & World Report. 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.”

Faculty from Children’s National Health System’s Department of Psychology & Behavioral Health set out to learn if any demographic, psychiatric, or cognitive factors play a role in determining if an adolescent should be eligible for bariatric surgery, and what their weight loss outcomes might be. Presenting at the Society for Pediatric Psychology Annual Conference earlier this month, a group of researchers, fellows and clinicians, including surgeons from Children’s National showcased their findings. One of the posters developed by Meredith Rose, LGSW, ML, who works as an interventionist on a Children’s National clinical research team, received special recognition in the Obesity Special Interest Group category.

One presentation reported on a total of 222 pediatric patients with severe obesity, which is defined as 120 percent of the 95th percentile for Body Mass Index. Mean age of the participants was 16 years of age, 71 percent were female and 80 percent where Hispanic or non-White. As part of their preparation for surgery, all patients were required to complete a pre-bariatric surgery psychological evaluation, including a clinical interview and Schedule for Affective Disorders and Schizophrenia (KSADS-PL) screening. The studies by the Children’s teams were based on a medical record review of the pre-screening information. Adolescents being evaluated for surgery had high rates of mental health diagnoses, particularly anxiety and depression, but also included Attention Deficit Hyperactivity Disorder, eating disorders, and intellectual disability.

Another Children’s presentation at the conference looked at weight loss outcomes for adolescents based on IQ and intellectual disability. Overall, neither Full Scale IQ from the Wechsler Abbreviated Intelligence Scale – 2nd edition, nor the presence of an intellectual disability predicted weight loss following surgery.

“The sum of our research found that kids do really well with surgery,” said Eleanor Mackey, PhD, assistant professor of psychology and behavioral health. “Adolescents, regardless of the presence of intellectual disability areas are likely to lose a significant amount of weight following surgery,” added Dr. Mackey.

“This is a particularly important fact to note because many programs and insurers restrict weight loss surgery to ‘perfect’ candidates, while these data points demonstrate that our institution does not offer or deny surgery on the basis of any cognitive characteristics,” says Evan P. Nadler, M.D., associate professor of surgery and pediatrics. “Without giving these kids a chance with surgery, we know they face a lifetime of obesity, as no other intervention has shown to work long-term in this patient population. Our research should empower psychologists and physicians to feel more confident recommending bariatric surgery for children who have exhausted all other weight loss options.”

The research team concluded that examining how individual factors, such as intellectual disability, psychiatric diagnoses, and demographic factors are associated with the surgery process is essential to ensuring adequate and empirically supported guidelines for referral for, and provision of bariatric surgery in adolescents. Next steps by the team will include looking into additional indicators of health improvement, like glucose tolerance, quality of life, or other lab values, to continue evaluating the benefits of surgery for this population.

Few prescribing options exist for obese kids

“We are making progress in expanding the number of medicines with pediatric labeling, but we need to do more concerning providing dosing guidelines for children with obesity,” says Janelle D. Vaughns, M.D., director of bariatric anesthesia at Children’s National and the lead study author.

Despite years of study and numerous public health interventions, overweight and obesity continue to grow in the U.S. Currently, more than two-thirds of adults have these issues, according to data from the Centers for Disease Control and Prevention. Children and adolescents also are being affected at an increasing rate: About one in five is obese. Obesity and overweight have been linked with a bevy of health problems, including Type 2 diabetes, high blood pressure, coronary heart disease and stroke.

Additionally, because obesity increases the percentage of fat tissue in relation to lean tissue and enlarges kidney size, it can affect how readily the body takes up, metabolizes and excretes medicines.

This latter issue can be particularly problematic in children, a population for whom relatively few drug studies exist. Now, a study team that includes Children’s National Health System researchers suggests that, despite the U.S. Congress providing incentives to drug manufacturers to encourage the study of medications in children, few approved drugs include safe dosing information for obese kids.

The study, performed in conjunction with the Food and Drug Administration’s (FDA) Center for Drug Evaluation and Research, surveyed pediatric medical and clinical pharmacology reviews under the FDA Amendments Act of 2007 and the FDA Safety and Innovation Act of 2012. The researchers used search terms related to weight and size to determine the current incorporation of obesity as a covariate in pediatric drug development.

Of the 89 product labels identified, none provided dosing information related to obesity. The effect of body mass index on drug pharmacokinetics was mentioned in only four labels, according to the study “Obesity and Pediatric Drug Development,” published online Jan. 19, 2018, in The Journal of Clinical Pharmacology.

“We are making progress in expanding the number of medicines with pediatric labeling, but we need to do more concerning providing dosing guidelines for children with obesity,” says Janelle D. Vaughns, M.D., director of bariatric anesthesia at Children’s National and the lead study author. “Moving forward, regulators, clinicians and the pharmaceutical industry should consider enrolling more obese patients in pediatric clinical trials to facilitate the safe and effective use of the next generation of medicines by obese children and adolescents.”

Study co-authors include Children’s Gastroenterologist Laurie Conklin, M.D., and Children’s Division Chief of Clinical Pharmacology Johannes N. van den Anker, M.D., Ph.D.; Ying Long, Pharm.D., University of Southern California; Panli Zheng, Pharm.D., University of North Carolina at Chapel Hill; Fahim Faruque, Pharm.D., University of Maryland; and Dionna Green, M.D., and Gilbert Burckart, Pharm.D., both of the FDA.

Celiac Program offers gluten-free diet app

gluten-free diet app

The Celiac Disease Program at Children’s National has created a new digital app for celiac disease and gluten-free diet management.

Celiac disease affects approximately one in 100 children, making it one of the most common conditions in children. To help patients and their families understand more about the disease and live a safe, gluten-free lifestyle, the Celiac Disease Program at Children’s National has created a gluten-free diet app.

The Celiac Disease and Gluten-Free Diet Digital Resource Center app was designed to offer all of the Celiac Disease Program’s educational tools in one place. “We have so many incredibly valuable resources, but all were housed in different places, making it very difficult to show people where to find them,” explains Vanessa Weisbrod, education director of the Celiac Disease program. “We created the app as a way to put everything in one place, but also as a mechanism for sharing our tools with the rest of the world.”

Available through the Apple App Store and Android Marketplace, the app gives users access to a variety of resources, including:

  • Safe and unsafe ingredient lists
  • Grocery store shopping tips
  • Gluten-free recipes accompanied by instructional cooking videos
  • Nutrition education
  • A monthly podcast
  • News feed of hot topics in the celiac and gluten-free community
  • Continuing education seminars led by celiac disease and gluten-free diet experts

“We are one of the few celiac programs in the country truly dedicated to developing high quality in-house patient education tools for families living with celiac disease,” says Weisbrod. “As we’ve shown our materials to other programs, they always ask us to share them. Through the app, anyone living a gluten-free lifestyle now has access to these remarkable tools.”

Cardiovascular and GI symptom relief

Photo of patient walking through the hallways

By adding antroduodenal manometry to the cardiovascular tilt table test, doctors in the GI Motility Program are able to collaborate with cardiologists to treat both cardiovascular and gastroenterological symptoms in children with complex orthostatic intolerance.

Physicians treating pediatric patients with complex orthostatic intolerance issues often face a double whammy – the children exhibit symptoms of their cardiovascular condition, but secondary issues relating to gastrointestinal functions are also common. That’s why cardiologists and gastroenterologists at Children’s National Health System have collaborated in recent years to diagnose and find comprehensive treatment solutions for patients with conditions such as neurally mediated hypotension (NMH) and postural orthostatic tachycardia syndrome (POTS).

Their innovative team approach was highlighted in a study of their first 35 patients from age 10-23, published in the Journal of Pediatric Gastroenterology and Nutrition last fall – patients who experienced relief for multiple symptoms thanks to treatment at Children’s National.

The collaboration is possible because of the advancements in gastroenterological diagnostics here – specifically related to the comprehensive GI Motility testing. While patients with POTS can exhibit an abnormal heart rate, low blood pressure, headaches, fatigue or weight loss, their gastroenterological symptoms like nausea and constipation are often under recognized, says Children’s Director of the Comprehensive GI Motility Program Anil Darbari, M.D., MBA, who co-authored the study with a team including Jeffrey Moak, M.D., Director of the Electrophysiology Program at Children’s.

Through antroduodenal manometry of the stomach and upper small intestine, in combination with the cardiovascular tilt table test, the team has been able to more accurately diagnose and treat these patients.

“We have the ability to do them together, thereby making the connection between these two conditions and providing a path for management or treatment,” Dr. Darbari said.

Typically, by the time he sees these patients, those with complex medical issues have often seen several other gastroenterologists at multiple centers, and have been through a lot. The study found that overall, antroduodenal manometry was abnormal in 26 of 35 (74%) patients either at baseline or during tilt table testing in subjects with orthostatic intolerance. Darbari and his colleagues concluded that upper GI motility studies should always be part of the comprehensive evaluation for this population of patients, because treating the autonomic condition improved their gastroenterological symptoms as well.

What does the future look like for this double-whammy approach?

“We have a cohort of over 100 patients with these issues who have been evaluated using this combined diagnostic approach,” Dr. Darbari said. “This gives the team the knowledge and opportunity to help even more kids, which is very rewarding.”

In addition to comprehensive assessment and medical approaches, Children’s National is home to leaders in minimally invasive laparoscopic and endoscopic diagnostic and corrective procedures that have enabled Children’s GI motility specialists and the teams they collaborate with to offer the next level of comprehensive pediatric medical care.

Drug dosing guidelines poor fit for obese patients

Children’s National researchers are among the top teams examining how obesity alters pharmacokinetics and the effect of body mass index on drug dosing and treatment outcomes specifically for pediatric and adolescent patients.

Obesity affects about 12.7 million U.S. children and adolescents – or about 1 in 6 kids across the nation, according to the Centers for Disease Control and Prevention. Despite this, there is a significant dearth of dosing guidelines for practitioners, for example pediatric anesthesiologists, to follow when administering potent anesthetics to pediatric patients who are obese.

Janelle D. Vaughns, M.D., director of bariatric anesthesia within the Division of Anesthesiology, Pain and Perioperative Medicine, says Children’s National Health System sees pediatric and adolescent patients of extreme weight (as much as 450 pounds) presenting for weight-loss surgery. In order to ensure that patients remain anesthetized during their surgical procedures, anesthesiologists use various classes of drugs, including hypnotics, muscle relaxants and pain medications. Dr. Vaughns says providers across the nation face similar challenges when determining accurate and precise dosing of drugs for obese pediatric patients.

“Medical guidelines calibrated for a 13-year-old of typical weight cannot be applied to a 13-year-old who weighs 400 pounds. Because morbid obesity in kids is a relatively new phenomenon in our country and globally, there are no formal guidelines to aid with dosing. In this scenario, most doctors extrapolate from guidelines written for lean patients. Because anesthetic drugs are so strong, it is essential to use the correct dose in all patients,” she says.

A recent brief report that Dr. Vaughns co-authored examines this issue. Researchers at Children’s National and the Washington Hospital Center conducted a retrospective review for 440 adult patients who received rapid sequence endotracheal intubation (RSI) in an urban, tertiary care academic Emergency Department. The patients received succinylcholine (a muscle relaxant) and etomidate (a short-acting anesthetic), whose doses are ideally calculated in milligrams per kilogram of total body weight.

The work, published in the December 2016 issue of American Journal of Emergency Medicine, reinforced the importance of data-driven guidelines for all patients. The research team found that the 129 obese patients included in the study were more likely to receive too little of the studied drugs while the 311 non-obese patients studied were more likely to receive too much medicine.

“Our single-center study demonstrates that obesity is a significant risk factor for underdosing RSI medications, whereas non-obesity is a risk factor for overdosing of these medications,” the research team concludes. This study also was reviewed and featured by the New England Journal of Medicine “Journal Watch” in October 2016.

Broadly, the issue of dosing potent medicines for pediatric obese patients is a national public health concern, Dr. Vaughns says. Research teams across the nation have made a concerted effort to publish papers on topics such as how obesity alters pharmacokinetics – how the body takes up, distributes and disposes of powerful medicines – and the deleterious effect of unhealthy body mass index on treatment outcomes for children with diseases such as acute myeloid leukemia.

Dr. Vaughns is among the clinician researchers working with the Pediatric Trials Network (PTN), sponsored by the Eunice Kennedy Shriver National Institute of Child Health and Human Development, to fill this research gap. Working as a team, she, Evan Nadler, M.D., a bariatric surgeon, and Johannes N. van den Anker, M.D., Ph.D., division chief of Clinical Pharmacology, enroll pediatric patients in ongoing trials with a special focus on surgical patients who are obese.

The network is currently conducting pediatric studies at a number of locations, including Children’s National, leveraging blood samples and other specimens drawn during regular care to better understand how medicines routinely used in pediatric patients actually work in kids and to determine appropriate dosing.

Ultimately, the information PTN researchers discover from their multi-year studies will help the Food and Drug Administration update medicine labels to reflect safer, more accurate and more effective dosing for all pediatric patients.

Minimally invasive surgery brings lasting relief to pediatric achalasia patients

tkane_atmospheric_2015

Achalasia affects only a small number of people around the world, estimated at 1.6 per 100,000, and children make up fewer than 5 percent of that total. In most cases, the causes are unknown, but it is attributed to a combination of heredity and autoimmune or nerve cell disorders. For adults, treatment might include oral medication to prevent narrowing, balloon dilation, or botulinum toxin injections to relax the muscle at the end of the esophagus. For a growing child, who faces not just months but a lifetime of injections and potential repeat procedures, these methods aren’t viable. Instead, surgical correction is the standard of care. In the past 10 years, the surgical option evolved from a traditional open procedure with weeks of recovery and pain to less-invasive approaches.

“The total number of children with achalasia is small,” says Timothy D. Kane, M.D., Division Chief of General and Thoracic Surgery at Children’s National Health System. “But Children’s National treats more of these cases than most other children’s hospitals around the world, and that gives us the ability to look at a larger population and see what works.”

Dr. Kane is senior author of a study recently published in the Journal of Pediatric Surgery that analyzed the outcomes from nearly a decade’s worth of these cases to gauge the effectiveness of two different minimally invasive surgical approaches for children with achalasia.

A look at the two surgical options

The most common surgical intervention is laparoscopic Heller myotomy, performed through small incisions in the belly. Additionally, Dr. Kane and the Children’s surgical team are one of only two teams in the country who perform a different procedure called peroral endoscopic myotomy (POEM) on children. The POEM procedure is completed entirely through the mouth using an endoscope, with no additional incision needed. The procedure is commonly used for adult achalasia cases, but is not widely available for children elsewhere as it requires specialized training and practice to perform.

“Heller myotomy works very well for most kids — that’s why it’s the standard of care,” Dr. Kane says. “Our study found that patients who underwent the POEM procedure experienced the same successful outcomes as Heller patients, and we already knew from adult data that POEM patients reported less pain following surgery — a win-win for children.”

The retrospective study included all children who had undergone surgical treatment for achalasia at Children’s from 2006 to 2015. Since achalasia cases are few and far between, with most children’s hospitals seeing maybe one to five cases over 10 years, collecting reliable data on outcomes is challenging. This study provides a large enough sample to allow doctors to use the findings as a guide to find the interventions that are the best fit for each patient.

“Now we’re very comfortable presenting families with two really good options and letting them choose the one that works best for them,” he concludes.

Imagine the feeling of food stuck in your throat. For children with esophageal achalasia, that feeling is a constant truth: The muscles in the esophagus fail to function properly and the lower valve, or sphincter, of the esophagus controlling the flow of food into the stomach doesn’t relax enough to allow in food — causing a backup, heartburn, chest pain, and many other painful symptoms. For children, surgery is the best hope for permanent relief.

Unbelievable survivability rates for short bowel patients

intestinal-rehabilitation-program_22350

When other doctors ask Clarivet Torres, M.D., how she is getting the best survivability rates for patients with Short Bowel Syndrome (SBS), she says her success is because of teamwork.

The Intestinal Rehabilitation Program (IRP) at Children’s National, started in 2007 when Dr. Torres joined the health system and became the program’s director, has shown 98 percent survivability for patients with SBS over a period of nine years. That’s compared with a recent study from the Pediatric Intestinal failure consortium (Predictors of Enteral Autonomy in Children’s with Intestinal Failure: a Multicenter Cohort Study), which showed that 43 percent of the patients died or underwent transplantation over a median follow-up of 33.5 months.

Intestinal failure often prevents these patients from digesting enough nutrients and fluids to maintain proper growth, and they often require parenteral nutrition (PN). Dr. Torres’ team has helped to wean 91.3 percent of patients from PN, compared with the above study, which showed that enteral autonomy was achieved in 43 percent.

Based on the outcomes for the first 120 children with SBS treated in Children’s National’s IRP from 2007 to 2016, Dr. Torres says that with meticulous and aggressive medical/surgical management, even patients with advanced liver disease can show improvement in liver functions and nutritional parameters with the ability to discontinue parenteral nutrition and avoid the need for transplantation.

“These are very, very good results for any program and ours has been growing substantially in the last 10 years,” Dr. Torres says. “We are like a family, we are very good at teaching so everyone knows how to care for these patients.”

Cross-departmental collaboration

Her main focus as director has been spreading the word about SBS across the departments. For example, the ER knows to start IV fluids on these patients right away or to keep watch for sepsis symptoms. From nurses, pediatric residents, and surgeons to radiologists and the ER, Dr. Torres has encouraged the sharing of knowledge and teaching how to respond to SBS patients.

Dr. Torres also attributes the success of the Children’s National’s program to having a multidisciplinary intestinal rehabilitation team who are trained to follow up with these highly complex patients with SBS.  “In general, these patients have a very high morbidity-mortality rate, and it’s important to be close to follow up.”

Members of  the IRP includes, a dedicated surgeon, Anthony Sandler, M.D., and four supporting GI doctors (Parvathi Mohan, M.D., Vahe Badalyan, M.D., Sona Sehgal, M.D., and Muhammad Khan, M.D.).

Other important members are one physician assistant, two nurse practitioners, two coordinators, one dietitian, one social worker, one case manager, and devoted nurses who work in the specialized Intestinal Rehabilitation Unit.

Having a dedicated director and surgeon also is a new perspective. Focusing on this group of patients allows Drs. Torres and Sandler to become experts in the medical and surgical management of the patients with short bowel and intestinal failure.

A closer look inside the program

The goal of the IRP is to optimize bowel function through the use of multiple therapies and to eventually wean patients with intestinal failure from parenteral nutrition. The medical treatment focuses on comprehensive dietary management with very precise control of metabolic balance and prompt and effective treatment of complications.

Pro-adaptive surgery, such as stoma closure, ostomy in continuity, stricturoplasty, enteroplasty, and autologous gut reconstruction, with the longitudinal intestinal lengthening and tailoring (LILT) and serial transverse enteroplasty (STEP) procedures, may produce dramatic clinical improvement in patients with SBS.

The use of specialized enteral feeding programs by the experience medical team helps to maintain nutrition and hydration, which are important factors in long-term survival. Other important components of the program are ongoing parent education and support, and promoting an optimal quality of life. Intestinal transplantation with MedStar Georgetown University Hospital is an option for patients who fail treatment.

“The Intestinal Rehabilitation at Children’s National provides children with intestinal failure the chance to receive comprehensive medical and surgical care, giving them the chance for improved long-term survival, including weaning from parenteral nutrition and avoidance of the need for transplantation and long-term immunosuppression,” Dr. Torres says.
