Nemours Biomedical Research
Nemours’ Center for Healthcare Delivery Science (CHDS) studies the many influences that can affect the outcomes, quality, cost, safety and value of children’s health care. Our goal is to build a strong base of scientific evidence about how health care can best be delivered so that children get exactly the care they need, right when they need it — and families feel that they have had an active role in that care.
We can achieve real gains in children’s health by learning how existing or new treatments can be selected and delivered efficiently to improve access, children’s outcomes and family satisfaction.
Researchers with the Center for Healthcare Delivery Science have been awarded research grants for a range of studies:
This project will explore the impact of trauma-informed patient care and the role of play in helping children and families heal and cope while in the hospital. The multiphase research will gather perspectives of patients/families of diverse backgrounds and healthcare providers regarding the need for, and best ways to deliver, trauma-informed pediatric patient care — an approach that incorporates awareness of the potentially traumatic nature of medical events and aims to reduce or prevent traumatic stress reactions in children. Research findings will be used to develop an innovative, high-quality program focused on trauma-informed care, using play materials and related resources designed to support and comfort children experiencing stress reactions due to life-threatening illness, injury or painful medical procedures.
The goal of this project is to adapt The Psychosocial Assessment Tool © (PAT) for use in the Autism population and pilot it in the Nemours Swank Autism Center.

Nemours is one of eight major pediatric care organizations comprising PedsNet that together were selected by the Patient-Centered Outcomes Research Institute (PCORI) as one of its 11 Clinical Data Research Networks. Nemours’ partners in PedsNet include Children’s Hospital of Philadelphia (the lead institution), Cincinnati Children’s Hospital and Medical Center, Boston Children’s Hospital, St. Louis Children’s Hospital, Nationwide Children’s Hospital, Children’s Hospital of Colorado and Seattle Children’s Hospital. PedsNet has combined de-identified electronic medical record data comprising 4.7 million clinical encounters and 2.3 million children from all eight organizations to create an exceptionally valuable resource for comparative effectiveness research on children’s health conditions.
During the 18-month Phase I of this grant support, which is complete, PEDSNet achieved a variety of technical and administrative milestones. In October 2015, PEDSNet was awarded Phase II funding that will enable completion of several research studies to demonstrate the network’s capabilities, to illustrate how other researchers can make use of this unique resource and to implement a sustainability plan over the next 3 years.

Taking care of children with type 1 diabetes who are under 6 years old is a huge challenge, and parental coping is a strong predictor of child health outcomes. In this three-year study, funded by the National Institutes of Health (NIH), principal investigators Tim Wysocki, PhD, ABPP, and Jessica Pierce, PhD, will coordinate the design and evaluation of a "social media portal" that will provide medically accurate, "parent to parent" guidance and support in coping with the daily hurdles that parents must somehow handle. The project will use "crowdsourcing" to obtain input from a 200-member Parent Crowd and a 30-member Health Care Provider Crowd over time to gradually design and build this internet resource for parents. Once the social media portal has been built and is working, the team will complete a randomized controlled trial to evaluate effects of using this resource on child health and behavioral outcomes and on parents' coping, distress and quality of life. Parents' patterns of using the social media portal and their thoughts about how it could be improved will also be measured periodically during the trial.
Following guidelines for the development and validation of measures, this study will ensure that the PAT Sibling Module has internal consistency, concurrent validity and predictive validity.
Spinal muscular atrophy (SMA) poses significant challenges to families. Research documents that the burden of this disease is high and escalates throughout the child’s life as functional abilities decline and complications increase. The psychosocial needs of these families, however, are not systematically assessed, leading to gaps in the delivery of psychosocial care. Melissa Alderfer, PhD, and her co-investigators Matthew Butchbach, MD, head of the Motor Neuron Diseases Research Group, and Mena Scavina, MD, attending pediatric neurologist, received a one-year Clinical Care Pilot award from CureSMA to develop a brief, standardized measure of family psychosocial risks and resources, based upon the Psychosocial Assessment Tool (PAT) and tailored to the challenges and demands associated with SMA. This tool will eventually provide a way to screen families in an effective and inclusive manner, systematically identifying those in need so that appropriate psychosocial care can be provided.

The delivery of psychosocial care to youth undergoing hematopoietic stem cell transplantation (HSCT) and their families lags behind existing scientific knowledge about the challenges experienced by patients and their families. This project will validate an adaptation of a brief parent report screener of family psychosocial risk — the Psychosocial Assessment Tool (PAT) for the particularly high-risk group of patients undergoing intensive treatments associated with HSCT, and integrate families in the development of clinical pathways of care for this high-risk population. This three-year project is funded by Alex’s Lemonade Stand and will be conducted at three sites: Nemours/Alfred I. duPont Hospital for Children, Cincinnati Children’s Hospital Medical Center and the University of Alabama-Birmingham's Division of Pediatric Hematology/Oncology at Children’s of Alabama Hospital.

Families of children with Sickle Cell Disease (SCD) face significant illness and life-related psychosocial adversity that can affect health outcomes and contribute to health disparities. There is currently a lack of validated and culturally-specific psychosocial screening measures for families of children with SCD. The purpose of this mixed methods study is to adapt the Psychosocial Assessment Tool (PAT) as a screening tool for psychosocial risk in families of children with SCD. The specific aims of the study include: 1) to assess caregiver perspectives on the acceptability and utility of the PAT in SCD, to help inform possible modifications to the measure, 2) derive risk factors from the PAT-SCD and evaluate the relationship between risk factors and relevant functional health and school outcomes; and 3) to establish the validity of the PAT-SCD and its psychometric properties. This study is one of several projects that are part of a 5-year funded grant from the National Institutes of Health Centers of Biomedical Research Excellence (NIH COBRE) to develop a comprehensive Sickle Cell Disease clinical and research center in the state of Delaware.
Nationally, fewer than 25% of adolescents with type 1 diabetes achieve glycated hemoglobin levels below 7.5%, a widely accepted indicator of acceptable blood glucose control. This NIH-funded (1-DP3-DK113235) project will engage an online community of adolescents with type 1 diabetes, parents and diabetes professionals in developing and refining a Transdisciplinary Care model for adolescents with type 1 diabetes. The researchers will then compare Transdisciplinary Care to Usual Care in a 1-year, randomized controlled trial. In the Transdisciplinary Care model, adolescents' and parents' diabetes clinic visits will be conjoint encounters with a nurse practitioner, dietitian and psychologist who will train each other in the fundamentals and methods of their respective professions.
This study aims to characterize the ways in which children with cancer and their parents make decisions around pain management at home and explore how this joint decision-making impacts children’s pain.

This study intervention consists of brief, tailored, culturally sensitive videos on the use of evidence-based parenting techniques for managing a child’s obesity-related behaviors and evaluates the impact of the intervention on parental self-efficacy, child behaviors and child weight.
This project consists of a one-day workshop to facilitate the implementation of The Psychosocial Assessment Tool© (PAT) in centers that treat children with cancer in Florida. The PAT is a brief parent report web-based screener, available in English and Spanish, that assesses psychosocial risk across the child and family’s social environment. The PAT was developed by Dr. Anne Kazak, who will be conducting the workshop in conjunction with Helena Gutierrez Richards, LCSW and other social workers at Nemours Children’s Specialty Care in Jacksonville who have been using the PAT in clinical practice since April 2015.

The Psychosocial Assessment Tool (PAT) is a parent report screener of psychosocial risk for families in pediatric health care. This project studies English and Spanish versions of the PAT in pediatric cancer to describe changes over time in risk, particularly for Spanish-speaking families, in an effort to identify factors related to health disparities in this population. The study is being conducted at Nemours/Alfred I. duPont Hospital for Children, The Children’s Hospital of Philadelphia (CHOP) and MD Anderson Cancer Center.
This is a senior scientist mentor award that provides for mentorship of multidisciplinary cancer researchers working on projects related to psychological intervention research.
Previous research suggests that siblings of children with cancer experience various negative emotions including guilt, loss, fear, grief, anger and helplessness These symptoms are not unexpected — childhood cancer in the family is an extreme stressor — and, with time, most siblings find ways to cope with their negative reactions and return to their previous levels of functioning. For some, however, these symptoms persist and can develop into troublesome emotional and behavioral problems. In this two-year study funded by the Andrew McDonough B+ Foundation, principal investigator Melissa A. Alderfer, PhD, will partner with SuperSibs, a program of the Alex's Lemonade Stand Foundation, to recruit 200 families of children with cancer from across the nation into a longitudinal study of sibling adjustment. Data will be collected at three points, approximately six months apart. Findings from this study will lead to a better understanding of the adjustment of siblings of children with cancer, and will distinguish early in the adjustment process those siblings who will prove to be resilient without intervention from those who require more support and assistance. Offering a rare contribution for this underserved and often unacknowledged population, this information is vital to embracing and promoting Nemours' commitment to family-centered care — ensuring that siblings of children with cancer are getting the right level of care to meet their unique needs.
Studies show that teens with diabetes benefit less than adults from new technologies such as insulin pumps and continuous glucose monitors. In this study, we will be developing and testing Web-delivered resources that are designed to help parents and teens with diabetes make better decisions about whether to add these devices to their care.
This project will plan and test automated feedback supports as part of the electronic medical record system to help doctors make the best decisions about children’s care.
This project addressed whether the delivery of behavioral interventions improved glycemic control and acute complications and whether healthcare costs lowered when behavioral interventions were part of care.
This study was an online adaptation of the Surviving Cancer Competently Intervention Protocol for facilitating coping with pediatric cancer.
