PTCIB supports research and training aimed at preventing, treating, and reducing all forms of childhood traumatic injury and critical illness across the continuum of care.

This includes research to understand the biobehavioral, psychosocial, and pathophysiologic aspects of trauma; to improve prevention, diagnosis, and treatment of traumatic injury and critical illness in infants, children, adolescents, and young adults; and to reduce secondary injury and comorbidities. 

 

Highlights

  • In response to concerns that COVID-related stay-at-home orders might correlate with increased incidences of child abuse, UNICEF has posted technical guidance designed to help authorities strengthen protection measures for children during the pandemic .
  • Highlights from selected branch-funded research:
    • Community prevention of child maltreatment (CM). In the first phase of an ongoing study, Dr. Kenneth Dodge and his team evaluated the long-term population impact and mechanisms of Family Connects (FC), a program designed to prevent CM in communities via brief home visits by nurses during an infant’s first 2 years. Between July 1, 2009, and December 31, 2010, every infant in Durham County, North Carolina, born on an even birth date (n=2,329 births) received the FC Program, and all infants born on an odd birth date (n=2,450 births) received regular community services. Evaluation indicated high penetration (80.0% of all births consented to participate), high fidelity to the model (84% adherence), and high reliability of scoring risk factors (Κ=0.69). Further evaluation with a representative random sample from intervention (n=269) and control (n=280) groups indicated that FC families accessed more community resources and exhibited less anxiety and better parenting behavior. Hospital records indicated FC families also had fewer emergency medical care visits and overnights in the hospital through age 24 months; child protective service records indicated 39% lower investigation rates for CM in FC families through age 60 months. These investigations indicate that a modest economic investment in a short-term, postpartum, universal home-visiting program like FC ($700/birth) could produce positive, sustained returns for communities over time. Dr. Dodge and his team suggest that building a continuum of support for families, such as integrating FC in infancy with another family-centered intervention in toddlerhood, present a promising possibility for supporting sustained population impact throughout early childhood and into the transition to kindergarten.

    • A mixed-method study of neighborhood factors and child maltreatment (CM). CM affects one in five children nationwide and often leads to profound physical, psychological, and behavioral consequences that may persist throughout life. Interventions to prevent CM are critically needed. Besides the inestimable cost in human suffering, CM’s material costs to society total more than $100 billion per year. Though most prevention efforts focus on individuals or families, the neighborhood is a key environment that both influences maltreatment rates and might serve as a potential intervention location to reduce CM. This branch-funded mixed-methods study found that neighborhood structural factors (e.g., economic disadvantage, residential instability, childcare burden, immigrant concentration) are linked to greater maltreatment, even after accounting for the effects of family and individual factors. Dr. James Spilsbury and his team examined the perceptions of neighborhood residents (n=400) and neighborhood-based child-welfare workers (n=260) in 20 neighborhoods in Cleveland, Ohio, on two neighborhood process measures: social disorder (risk factor) and collective efficacy (protective factor). Child-welfare workers and residents needed to reach a common understanding of these factors to also agree on the safety of children in these neighborhoods. Multilevel modeling, taking into account individual and neighborhood characteristics, showed that child-welfare workers consistently perceived higher social disorder and lower collective efficacy compared to residents. Neighborhood characteristics were associated with residents' and child-welfare workers' perspectives on social disorder in different ways, and these differences have implications for better understanding the context and improving the effectiveness of neighborhood-based interventions to prevent CM.

    • Clinical decision rules to identify bruising caused by physical child abuse (PCA). Many cases of PCA are missed initially because early signs of abuse, such as bruising, go unrecognized. This lack of recognition leads to errors in decision-making, which leads to poor patient outcomes. When abuse is missed, repeat injury occurs in up to 80% of victims, with mortality rates as high as 30%. Bruising is one of the most common signs of PCA and is missed as an early warning sign in up to 44% of fatal and near-fatal cases. Although no evidence-based guidelines currently exist to aid clinicians in distinguishing between bruises caused by PCA versus accidental trauma, evidence from several studies indicates that discriminating characteristics do exist. The predictive accuracy of these findings has not yet been determined or incorporated into a practical decision-making model, such as a clinical decision rule, for the acute care setting. In this study, Dr. Mary Clyde Pierce and colleagues provide the first practical screening tool in the form of a Bruising Clinical Decision Rule (BCDR) for classifying bruises caused by PCA in children older than 4 years of age. This observational study builds on the team’s previous work in which they derived a BCDR with 97% sensitivity and 84% specificity for identifying bruises caused by PCA. findings suggest that once infants begin to cruise (i.e., walk while holding onto objects), they are more likely to bruise. Three studies of clinic patients ranging from 6 to 12 months of age yielded prevalence of 12%-13%, with increased mobility associated with increased bruising. The prevalence rate for this study also increased within age strata but was only half that reported for the 6- to 12-month-olds. The reason for the higher rate of infant bruising in a well-child clinic population compared to a pediatric emergency department (ED) population is not clear. However, the oldest patients in the study sample (11 and 12 months of age) exhibited a more comparable prevalence rate of 10%. Studies of high-risk and/or abuse populations yielded the highest bruising prevalence rates, ranging from 25.9% for children referred to child abuse teams to 72% for children who died from abusive head trauma. The relatively low prevalence of bruising in healthy well-child and ED visits in the first year of life compared to that among populations referred for or dying from abuse underscores the importance of this physical examination finding and indicates that even a seemingly simple finding can be ominous and requires clinical due diligence.

    • Dissemination and implementation of the Safe Environment for Every Kid (SEEK) model for preventing child abuse and neglect. The Centers for Disease Control and Prevention’s Healthy People 2020 goals call for reducing fatal and nonfatal child maltreatment (CM). Achieving this goal hinges on broad implementation of effective, evidence-based preventive interventions, such as the SEEK model , developed for pediatric primary care. Primary care offers an excellent opportunity to help address prevalent psychosocial problems (e.g., parental depression) that are risk factors for CM. By addressing such problems, SEEK can strengthen families and support parents, and thereby promote children’s health, development, and safety; help prevent CM; and benefit the health of the U.S. population. Dr. Howard Dubowitz and his team are examining intervention strategies aimed at optimizing SEEK’s adoption, implementation, and sustainment and the strategies’ effectiveness in helping prevent CM. Notably, the overarching goal of the study is to examine two technology-driven implementation strategies to scale up SEEK in pediatric and family medicine primary care settings. The knowledge gained from this study will help improve pediatric primary care to better address prevalent psychosocial problems and benefit children and their families. The outcomes will also help build the field of implementation science and guide future interventions addressing social determinants of child health.
