Healthcare Delivery Science

Nemours Children's Health 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.

Current Studies

Researchers with the Center for Healthcare Delivery Science have been awarded research grants for a range of studies:

Trauma Informed Care for Children and Families in Pediatric Healthcare
Toy Industry Foundation

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.

Screening for Family Psychosocial Risk in Pediatric Sickle Cell Disease

NIH Centers of Biomedical Research Excellence (COBRE)

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.

Trajectories of Sibling Adjustment to Childhood Cancer: The First Two Years Postdiagnosis

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.

A Crowdsourced Social Media Portal for Parents of Very Young Children With Type 1 Diabetes

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 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.

Screening for Psychosocial Risk Among Families of Children With Spinal Muscular Atrophy

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.

Our Centers

Center for Healthcare Delivery Science

The Nemours Center for Healthcare Delivery Science (CHDS) is a research center across the Nemours Children’s Health System directed by Anne E. Kazak, PhD, ABPP, in Wilmington, Del. Founded in 2012, the center consists of an interdisciplinary team of research scientists, physicians and pediatric psychologists who apply scientific methods and principles to the analysis of variables and processes that affect the delivery, safety, outcomes, cost, quality and value of pediatric health care.

Key areas of research include clinical decision making, family adaptation to pediatric chronic medical conditions, health informatics, transition from pediatric to adult care, cancer care delivery research and family adjustment, including psychosocial risk screening in pediatric illness. Funding is provided by grants and contracts from the National Institutes of Health, Patient-Centered Outcomes Research Institute, American Cancer Society, the Department of Defense, Substance Abuse and Mental Health Services Administration, and private foundations.

A number of research studies are joint efforts with the Center for Pediatric Traumatic Stress (CPTS), a Center within the National Child Traumatic Stress Network that focuses on the development of empirically based screening and intervention for children and families who have experienced traumatic stress due to pediatric illness and injury. Center investigators provide mentoring and consultation to colleagues who may wish to conduct research in health care delivery science.

The Center for Healthcare Delivery Science helps Nemours to be among the top 5 percent of all U.S. pediatric health care organizations by:

  • using Nemours’ advanced electronic health record system to show the quality and value of health care we deliver
  • teaching Nemours medical staff how findings from health care delivery science research can be applied in their practices
  • helping Nemours care teams identify research questions and design research that can improve the quality, cost and value of care
  • attracting skilled researchers to conduct health care delivery science at Nemours
  • obtaining more funding for Center for Healthcare Delivery Science research, including studies based at Nemours and multisite national investigations

A number of studies are joint efforts with the Center for Pediatric Traumatic Stress (CPTS), founded in 2002 to address medical trauma in the lives of children and families. The center is colocated at Nemours Children’s Hospital, Delaware and Children’s Hospital of Philadelphia.

The Center for Pediatric Traumatic Stress (CPTS) addresses health-related trauma in the lives of children and families. The center's mission is to reduce medical traumatic stress by promoting trauma-informed health care, integrating practical evidence-based tools into pediatric medical care, and ensuring that health care providers are knowledgeable and skilled in trauma-informed care for culturally diverse youth and their families. CPTS has developed and evaluated acute and brief family-focused interventions, which can be integrated within pediatric health care.

The center’s current goals are to:

  • engage and provide national expertise to health care providers and health care systems in improving outcomes for children and families with medical trauma
  • adapt, disseminate and provide training to mental health providers in trauma-informed assessments and interventions for children and families experiencing medical trauma
  • ensure that children and families have access to evidence-based resources and interventions that address the impact of medical trauma
  • equip other child-serving systems with trauma-informed approaches to address injury, illness and medical problems in children and families

Activities to achieve these goals include:

  • promoting professional and public awareness of medical trauma via CPTS's active web presence and the CPTS partnership with national health provider organizations
  • supporting implementation of effective assessment and intervention for medical trauma in health care settings
  • delivering training on and tools for assessment and intervention with medical trauma to health and mental health providers
  • disseminating trauma-focused resources in English and Spanish to children and families experiencing medical trauma
