Association of a Postnatal Parent Education Program for Abusive Head Trauma With Subsequent Pediatric Abusive Head Trauma Hospitalization Rates

Shaking Up Our Approach: The Need for Characterization and Optimization of Pre-clinical Models of Infant Abusive Head Trauma

Traumatic brain injuries (TBIs) are a large societal and individual burden. In the first year of life, the vast majority of these injuries are the result of inflicted abusive events by a trusted caregiver. Abusive head trauma (AHT) in infants, formerly known as shaken baby syndrome, is the leading cause of inflicted mortality and morbidity in this population. In this review we address clinical diagnosis, symptoms, prognosis, and neuropathology of AHT, emphasizing the burden of repetitive AHT. Next, we consider existing animal models of AHT, and we evaluate key features of an ideal model, highlighting important developmental milestones in children most vulnerable to AHT. We draw on insights from other injury models, such as repetitive, mild TBIs (RmTBIs), post-traumatic epilepsy (PTE), hypoxic-ischemic injuries, and maternal neglect, to speculate on key knowledge gaps and underline important new opportunities in pre-clinical AHT research. Finally, potential treatment options to facilitate healthy development in children following an AHT are considered. Together, this review aims to drive the field toward optimized, well-characterized animal models of AHT, which will allow for greater insight into the underlying neuropathological and neurobehavioral consequences of AHT.

Abusive head trauma and crying infant-Public awareness of newborn and infant trauma

AIM

Crying seems to be a common trigger for abusive head trauma (AHT), which is the leading cause of fatalities from physical abuse in infants. Our objective was to evaluate knowledge of AHT, crying infants and correct behavioural measures in a general population.

METHODS

An online questionnaire (LimeSurvey) was created to assess the risk of shaking. The online survey contained a total of 41 questions, including a demonstration of a previously recorded video in which an infant doll is shaken.

RESULTS

A total of 319 people, 245 of them (76.8%) with own children, participated in the study. Almost all respondents (98.4%) were aware of serious injuries due to shaking, even to the point of death (98.1%). Most participants (97.5%) had heard the term 'shaking trauma' prior but did not receive any professional information, neither before nor after birth (85.2% or 86%), or during follow-up examinations (88.5%). The majority of the participants (95%) considered that useful coping strategies in infant crying were inappropriate.

CONCLUSION

The consequences of shaking an infant were common knowledge in a normal population, whereas there was a knowledge gap regarding the management of excessive crying infants. Prevention programmes should mainly focus on male caregivers during postnatal care.

The Effectiveness of Parenting Programs in Preventing Abusive Head Trauma: A Systematic Review and Meta-Analysis

Parenting programs are the most common intervention for preventing the lethal form of child maltreatment, abusive head trauma (AHT). However, certain results of the effects of these programs have not yet been compared across studies. A systematic review with meta-analysis is warranted to quantitively synthesize the available evidence to identify effective elements and strategies of the programs for preventing AHT. This review aims to estimate AHT preventive parenting programs' pooled effect on the reduction of AHT incidence, the improvement of parental knowledge, and the increased use of safe strategies in response to infants' inconsolable crying. Studies published in English and Mandarin were searched and retained if they were randomized control trials (RCTs) or with a quasi-experimental design, included an AHT preventive parenting program, and provided data that quantified targeted outcomes. Eighteen studies were included in this review. AHT preventive parenting programs had a pooled effect on improving parents' knowledge and increasing the use of safe coping strategies in response to inconsolable crying but not on the incidence of AHT and parents' emotional self-regulation. Subgroup analyses showed that the intervention effects were mostly present across study designs or measurements and emerged in the reduction of AHT incidence compared with historical controls. The findings suggest that AHT preventive parenting programs enhance parenting knowledge and skills to provide safe care for infants. Further efforts to evaluate AHT parenting programs on the reduction of AHT incidence are necessary for decision-making on allocating and disseminating interventions.

ICD-10 codes for surveillance of non-fatal abusive head trauma in Aotearoa New Zealand: a retrospective cohort study

OBJECTIVES

To assess the validity of an International Classification of Diseases (ICD) code based definition of non-fatal head trauma caused by child abuse (abusive head trauma) for population surveillance in New Zealand.

DESIGN

A retrospective cohort study of hospital inpatient records.

SETTING

A tertiary children's hospital in Auckland, New Zealand.

PARTICIPANTS

1731 children less than 5 years of age who were discharged after a non-fatal head trauma event over a 10-year period from 1 January 2010 to 31 December 2019.

OUTCOME MEASURES

The outcome of assessment by the hospital's multidisciplinary child protection team (CPT) was compared with the outcome of ICD, Tenth Revision (ICD-10) discharge coding for non-fatal abusive head trauma (AHT). The ICD-10 code definition of AHT was derived from an ICD, Ninth Revision, Clinical Modification definition developed by the Centers for Disease Control, Atlanta, Georgia, which requires both a clinical diagnosis code and a cause-of-injury code.

RESULTS

There were 1755 head trauma events with 117 determined as AHT by the CPT. The ICD-10 code definition had a sensitivity of 66.7% (95% CI 57.4 to 75.1) and specificity of 99.8% (95% CI 99.5 to 100). There were only three false positives but 39 false negatives, with 18 of the false negatives coded with X59 (exposure to unspecified factor).

CONCLUSIONS

The ICD-10 code broad definition of AHT is a reasonable epidemiological tool for passive surveillance of AHT in New Zealand but it underestimates the incidence. Its performance could be improved by clear documentation of child protection conclusions in clinical notes, clarifying coding practice and removing the exclusion criteria from the definition.

Traumatic head injury due to child maltreatment: epidemiology, cost analysis, and impact of prevention

BACKGROUND

Traumatic head injury due to child maltreatment (THI-CM), also known as abusive head trauma (AHT), is a significant public health problem due to the wide array of consequences affecting multiple domains of a child's health and development. Several studies have evaluated its cost on healthcare systems, families, and societies. Many jurisdictions have implemented caregiver education programs to prevent THI-CM.

OBJECTIVES

This paper aims to provide a brief overview of the epidemiology and cost analysis of THI-CM and discuss its prevention and the intergenerational transmission of child maltreatment.

METHODS

Although not systematic, a literature search of original articles published from 2000 to 2022 in English and French was undertaken using the following databases: PubMed, EMBASE (Ovid), and PsycINFO (OVID). The search combined terms related to traumatic head injury and child maltreatment, with terms related to its cost and prevention. Studies of children aged 0-5 years old were included. The authors completed a screen of the titles and abstracts to determine relevance with respect to this article.

RESULTS

Globally, although THI-CM accounts for a small proportion of cases of child maltreatment, there is a high incidence of death and neurological sequelae compared to other causes of head trauma.The incidence of THI-CM is likely underestimated due to the lack of standardized definitions, differences in reporting, and challenges in identifying less severe cases. Cost analysis studies reveal the significant short- and long-term costs associated with THI-CM. Caregiver education programs have been studied and implemented in many centers and have shown varying but promising results.

CONCLUSION

A multi-pronged approach to prevention efforts should be considered to support families and help to prevent THI-CM and maltreatment throughout childhood.

Educational interventions to prevent paediatric abusive head trauma in babies younger than one year old: A systematic review and meta-analyses

BACKGROUND

Paediatric abusive head trauma (AHT) occurs in young children due to violent shaking or blunt impact. Educational and behavioural programmes modifying parent/infant interactions may aid primary prevention. This systematic review aims to assess the effectiveness of such interventions to prevent AHT in infants.

METHODS

We searched Embase, MEDLINE, PsycINFO, The Cochrane library, CINAHL databases and trial registries to September 2021, for studies assessing the effectiveness of educational and behavioural interventions in preventing AHT. Eligible interventions had to include messaging about avoiding or dangers of infant shaking. Randomised controlled trials (RCTs) reporting results for primary (AHT, infant shaking) or secondary outcomes (including parental responses to infant crying, mental wellbeing), and non-randomised studies (NRSs) reporting primary outcomes were included. Evidence from combinable studies was synthesised using random-effects meta-analyses. Certainty of evidence was assessed using GRADE framework. PROSPERO registration CRD42020195644.

FINDINGS

Of 25 identified studies, 16 were included in meta-analyses. Five NRSs reported results for AHT, of which four were meta-analysed (summary odds ratio [OR] 0.95, 95 % confidence intervals [CI] 0.80-1.13). Two studies assessed self-reported shaking (one cluster-RCT, OR 0.11, 95 % CI 0.02-0.53; one cohort study, OR 0.36, 95 % CI 0.20-0.64, not pooled). Meta-analyses of secondary outcomes demonstrated marginal improvements in parental response to inconsolable crying (summary mean difference 1.58, 95 % CI 0.11-3.06, on a 100-point scale) and weak evidence that interventions increased walking away from crying infants (summary incidence rate ratio 1.52, 95 % CI 0.94-2.45). No intervention effects were found in meta-analyses of parental mental wellbeing or other responses to crying.

INTERPRETATION

Low certainty evidence suggests that educational programmes for AHT prevention are not effective in preventing AHT. There is low to moderate certainty evidence that educational interventions have no effect or only marginally improve some parental responses to infant crying.

Complex Pathophysiology of Abusive Head Trauma with Poor Neurological Outcome in Infants

Abusive head trauma (AHT) in infants, especially acute subdural hematoma, has an extremely poor outcome. The most decisive and important finding is the appearance of a widespread low-density area on head computed tomography. This phenomenon was traditionally thought to be caused by cerebral ischemia. However, many other pathophysiological abnormalities have been found to be intricately involved. Recent studies have found that status epilepticus and hyperperfusion injures are the major causes. Another serious problem associated with AHT is cardiopulmonary arrest (CPA). Many infants are reported to visit to the hospital with CPA, and its pathophysiology has not been fully elucidated. This paper examines the background of these pathological conditions and associated factors and elucidate the pathophysiological mechanisms resulting in poor outcomes in AHT. In addition to the intensity of assault on the head, the peculiar pathophysiological characteristics in infants, as well as the social background specific to child abuse, are found to be associated with poor outcome.

The role of household composition of children diagnosed with abusive head trauma

BACKGROUND

To prevent abusive head trauma (AHT), many studies focus on understanding the risk factors. Few studies assess the role of household composition.

OBJECTIVE

To describe the household composition of children diagnosed with AHT and assess the relationships between patient and household characteristics, perpetration, and fatality.

PARTICIPANTS AND SETTING

Children admitted to a large pediatric hospital with AHT between January 1, 2010 and December 31, 2019.

METHODS

The diagnosis of AHT was made at initial hospitalization by a child abuse pediatrician with a multidisciplinary team review. The electronic medical records of identified patients were reviewed to identify demographic information, the number and ages of all of their siblings and the number and relationship to patients of all adults who were reported as being present at the time of AHT and therefore considered to be possible perpetrators. Descriptive statistics were used to characterize the sample. Comparisons were made using Fisher exact tests and Mann-Whitney tests.

RESULTS

Children with AHT who were under 12 months of age and had siblings in the home, particularly siblings under age 5, had greater odds of being injured by a biological parent. Children 12 months or older and children without siblings had greater odds of being injured by a boyfriend or girlfriend of their parent or guardian.

CONCLUSIONS

In cases of AHT, the possible perpetrator differed based on the presence of young siblings living in the home, which has important implications for AHT prevention.

Incidence of hospitalization for abusive head trauma in Chiba City, Japan

BACKGROUNDS

This study aimed to examine the incidence of abusive head trauma (AHT) admissions by calculating admission rates of AHT cases among infants <12 months old in a population-based sample in Chiba city, Chiba prefecture, Japan.

METHODS

We retrospectively examined medical records of infants admitted to all pediatric secondary and tertiary hospitals in Chiba city between 2011 and 2015. We collected 13 AHT cases, as assessed by hospital-based multidisciplinary child protection teams. One experienced pediatric radiologist and two pediatricians evaluated the case histories and computed tomography images of cases to evaluate them clinically as "strongly" or "moderately" suspected AHT.

RESULTS

The overall incidence per 100 000 person-years was 34.5 cases (95% confidence interval (CI): 18.4-59.1), of which 13.3 (95% CI: 4.3-31.0), were strongly suspected to be AHT and 21.3 (95% CI: 9.2-41.9) were moderately suspected. There were no statistical differences in computed tomography findings between severe and moderately suspected AHT.

CONCLUSIONS

The incidence of hospitalization of infants with AHT was similar to that reported in population-based studies in other countries.

Underestimating isolated bilateral hygroma as non-accidental head injury with dramatic consequences: a case presentation

OBJECTIVE

Abusive head injury (AHI) in infancy is associated with significantly worse outcomes compared to accidental traumatic brain injury. The decision-making of the diagnosis of AHI is challenging especially if the clinical signs are not presenting as a multifactorial pattern.

METHOD

We present a case of isolated bilateral hygroma in which this differential diagnosis of AHI was evaluated but primarily not seen as such leading subsequently to extensive secondary AHI with fatal brain injury.

RESULTS

The case of an 8-week-old infant with apparently isolated bilateral hygroma without any external signs of abuse and no retinal hemorrhages was interpreted in causative correlation to the perinatal complex course of delivery. At a second readmission of the case, severe brain injury with bilateral cortical hypoxia, subarachnoid and subdural hemorrhages, and skull and extremity fractures led to severe disability of the affected infant.

CONCLUSION

Any early suspicion of AHI with at least one factor possibly being associated with abusive trauma should be discussed in multidisciplinary team conferences to find the best strategy to protect the child. Beside clinical factors, social factors within the family household may additionally be evaluated to determine stress-related risk for traumatic child abuse. In general, prevention programs will be essential in future perspective.

Do Victims of Abusive Head Trauma Visit Emergency Departments More Often Than Children Hospitalized for Fever? A Case-Control Study

OBJECTIVE

During the first years of life, infant crying is a common trigger of abusive head trauma (AHT). Emergency department (ED) use by AHT victims before visits for child abuse symptoms is not well known, particularly for infant crying. Furthermore, diagnosis could be missed. In the same period, fever is a common reason for hospitalization unconnected with AHT. The main goal of our study was to compare the ED use by AHT victims before visits for child abuse symptoms and by children of the same age hospitalized for fever.

METHODS

We conducted a retrospective case-control study from 2011 to June 2018 in a French hospital. We compared cases of AHT selected using the International Classification of Diseases and control subjects hospitalized in the general pediatric unit for fever without immunodeficiency matched in age. Univariate and multivariate analyses were performed.

RESULTS

Among the 75 victims of AHT, 5 had at least 1 previous ED visit not linked with abuse. None had visited for infant crying. Among the control subjects, 34 had at least 1 previous ED visit, including 6 for infant crying. Among the 57 dyads of controls and cases living in the hospital's area, the controls had significantly more previous ED visits than the cases (P < 0.001). There were more male infants among the cases (72% vs. 55%, P = 0.033).

CONCLUSIONS

Our study suggests that AHT victims had no more ED visits before visits for child abuse symptoms, particularly not for infant crying.

State Spending on Public Benefit Programs and Child Maltreatment

BACKGROUND

To determine the association between states' total spending on benefit programs and child maltreatment outcomes.

METHODS

This was an ecological study of all US states during federal fiscal years 2010-2017. The primary predictor was states' total annual spending on local, state, and federal benefit programs per person living ≤100% federal poverty limit, which was the sum of (1) cash, housing, and in-kind assistance, (2) housing infrastructure, (3) child care assistance, (4) refundable Earned Income Tax Credit, and (5) Medical Assistance Programs. The main outcomes were rates of maltreatment reporting, substantiations, foster care placements, and fatalities after adjustment for relevant confounders. Generalized estimating equations adjusted for federal spending and estimated adjusted incidence rate ratios (IRRs) and 95% confidence intervals (CIs).

RESULTS

States' total spending was inversely associated with all maltreatment outcomes. For each additional $1000 states spent on benefit programs per person living in poverty, there was an associated -4.3% (adjusted IRR: 0.9573 [95% CI: 0.9486 to 0.9661]) difference in reporting, -4.0% (adjusted IRR: 0.903 [95% CI: 0.9534 to 0.9672]) difference in substantiations, -2.1% (adjusted IRR: 0.9795 [95% CI: 0.9759 to 0.9832]) difference in foster care placements, and -7.7% (adjusted IRR: 0.9229 [95% CI: 0.9128 to 0.9330]) difference in fatalities. In 2017, extrapolating $1000 of additional spending for each person living in poverty ($46.5 billion nationally, or 13.3% increase) might have resulted in 181 850 fewer reports, 28 575 fewer substantiations, 4168 fewer foster care placements, and 130 fewer fatalities.

CONCLUSIONS

State spending on benefit programs was associated with reductions in child maltreatment, which might offset some benefit program costs.

Inequities in Pediatric Abusive Head Trauma According to Neighborhood Social and Material Deprivation: A Population-Level Study in British Columbia, Canada

OBJECTIVES

To explore the relationship between neighborhood social and material deprivation and the rates of abusive head trauma (AHT), and whether it differs according to sex, and following the implementation of the Period of PURPLE Crying (PURPLE) program.

METHOD

A cross-sectional study design was applied to data from children 0 to 24 months old with a confirmed AHT diagnosis between 2005 and 2017 in British Columbia. Dissemination area-based social and material deprivation scores were assigned to residential areas, where AHT cases were recorded. Poisson regression models tested the relationship between deprivation scores and AHT rates, adding sex and pre-post program implementation as interaction terms.

RESULTS

With each increase in material and social deprivation quintiles, AHT rates increased by 42% (95% CI [1.18, 1.72]) and 25% (95% CI [1.06, 1.51]), respectively, following a social gradient. AHT rate disparities between neighborhoods did not change following the PURPLE program implementation.

CONCLUSIONS

This study stresses the need to provide additional AHT prevention services proportionately to the levels of neighborhood disadvantage, in addition to universal AHT programs, to successfully protect all children.

Making the Most of Clinical Encounters: Prevention of Child Abuse and Maltreatment

Child abuse is a public health concern with great costs to children, families, and society. Prevention of child abuse and maltreatment is an important clinical skill. Providers can take advantage of the opportunity to offer prevention interventions in the health care setting. Identification of risk factors and signs and symptoms of abuse, referral to local resources, parenting education, and application of the public health prevention framework should be integrated into clinical encounters. Identification of sentinel injuries enables tertiary interventions to save lives. Primary interventions during early childhood using effective parenting programs has been shown to reduce child maltreatment.

Parents' Perceptions of Infant Crying: A Possible Path to Preventing Abusive Head Trauma

OBJECTIVE

Infant crying can lead to parental frustration and is the most common trigger for abusive head trauma (AHT). We used qualitative methodology with an activating stimulus (an audiotape of an infant crying) to prime the participants to engage in open dialogue for the purpose of understanding their perceptions of infant crying and its association with AHT, with the aim that information from these interviews and the impact of hearing the activating stimulus could be used to inform interventions to prevent AHT that would resonate with parents.

METHODS

We conducted 25 initial qualitative interviews and 16 subsequent interviews with mothers and fathers of newborns. Before the initial interview, parents listened to a 1-minute audio clip of a crying infant, followed by a preventive message regarding AHT. The transcribed data were analyzed, and themes were developed using the constant comparative method of grounded theory. Data collection and analysis continued past the point of thematic saturation.

RESULTS

Four themes emerged from the initial interviews: 1) previous experience is helpful to manage infant crying, 2) babies cry for a reason, 3) shaking an infant is incomprehensible to parents, and 4) the role of safety planning to manage frustration with crying. Analysis of the subsequent interviews revealed 2 additional themes: 1) use of supports for infant crying (eg, technology and physician advice) and 2) effects of the audio clip on caregiving practices.

CONCLUSION

Previous experiences and beliefs about crying affect parents' perceptions of infant crying and AHT. After discharge, parents reported using technology for information and support and thinking about the audio clip when caring for their infant. These experiences, beliefs, and practices may aid in shaping effective prevention strategies to prevent AHT.

Abusive Head Trauma in Infants and Children

Abusive head trauma (AHT) remains a significant cause of morbidity and mortality in the pediatric population, especially in young infants. In the past decade, advancements in research have refined medical understanding of the epidemiological, clinical, biomechanical, and pathologic factors comprising the diagnosis, thereby enhancing clinical detection of a challenging diagnostic entity. Failure to recognize AHT and respond appropriately at any step in the process, from medical diagnosis to child protection and legal decision-making, can place children at risk. The American Academy of Pediatrics revises the 2009 policy statement on AHT to incorporate the growing body of knowledge on the topic. Although this statement incorporates some of that growing body of knowledge, it is not a comprehensive exposition of the science. This statement aims to provide pediatric practitioners with general guidance on a complex subject. The Academy recommends that pediatric practitioners remain vigilant for the signs and symptoms of AHT, conduct thorough medical evaluations, consult with pediatric medical subspecialists when necessary, and embrace the challenges and need for strong advocacy on the subject.

Advances and Future Directions of Diagnosis and Management of Pediatric Abusive Head Trauma: A Review of the Literature

Abusive head trauma (AHT) is broadly defined as injury of the skull and intracranial contents as a result of perpetrator-inflicted force and represents a persistent and significant disease burden in children under the age of 4 years. When compared to age-matched controls with typically single occurrence accidental traumatic brain injury (TBI), mortality after AHT is disproportionately high and likely attributable to key differences between injury phenotypes. This article aims to review the epidemiology of AHT, summarize the current state of AHT diagnosis, treatment, and prevention as well as areas for future directions of study. Despite neuroimaging advances and an evolved understanding of AHT, early identification remains a challenge for contemporary clinicians. As such, the reported incidence of 10–30 per 100,000 infants per year may be a considerable underestimate that has not significantly decreased over the past several decades despite social campaigns for public education such as “Never Shake a Baby.” This may reflect caregivers in crisis for whom education is not sufficient without support and intervention, or dangerous environments in which other family members are at risk in addition to the child. Acute management specific to AHT has not advanced beyond usual supportive care for childhood TBI, and prevention and early recognition remain crucial. Moreover, AHT is frequently excluded from studies of childhood TBI, which limits the precise translation of important brain injury research to this population. Repeated injury, antecedent abuse or neglect, delayed medical attention, and high rates of apnea and seizures on presentation are important variables to be considered. More research, including AHT inclusion in childhood TBI studies with comparisons to age-matched controls, and translational models with clinical fidelity are needed to better elucidate the pathophysiology of AHT and inform both clinical care and the development of targeted therapies. Clinical prediction rules, biomarkers, and imaging modalities hold promise, though these have largely been developed and validated in patients after clinically evident AHT has already occurred. Nevertheless, recognition of warning signs and intervention before irreversible harm occurs remains the current best strategy for medical professionals to protect vulnerable infants and toddlers.

Abusive head trauma: evidence, obfuscation, and informed management

Abusive head trauma remains the major cause of serious head injury in infants and young children. A great deal of research has been undertaken to inform the recognition, evaluation, differential diagnosis, management, and legal interventions when children present with findings suggestive of inflicted injury. This paper reviews the evolution of current practices and controversies, both with respect to medical management and to etiological determination of the variable constellations of signs, symptoms, and radiological findings that characterize young injured children presenting for neurosurgical care.

The lifetime costs of pediatric abusive head trauma and a cost-effectiveness analysis of the Period of Purple crying program in British Columbia, Canada

BACKGROUND

Abusive head trauma (AHT) is a severe form of child abuse causing devastating outcomes for children and families, but its economic costs in Canada has yet to be determined. The Period of PURPLE crying program (PURPLE) is an AHT prevention program implemented in British Columbia for which success in reducing AHT events was recently reported.

OBJECTIVE

This study estimated the lifetime costs to society of incidental AHT events and compared the benefits and associated costs of AHT before and after the implementation of the PURPLE program.

PARTICIPANTS AND SETTING

Children aged 0-24 months old with a definite diagnosis of AHT between 2002 and 2014 in British Columbia were included in this study.

METHODS

An incidence-based cost-of-illness analysis, using the human capital approach was used to quantify the lifetime costs of AHT events according to their severity (least severe, severe and fatal). A cost-effectiveness analysis of the PURPLE program was conducted from both a societal and a health services' perspectives using decision tree models.

RESULTS

There were sixty-four AHT events between 2002-2014, resulting in a total cost of $354,359,080 to society. The costs associated with fatal, severe and least severe AHT averaged $7,147,548, $6,057,761 and $1,675,099, respectively. The investment of $5 per newborn through the PURPLE program resulted in a $273.52 and $14.49 per child cost avoidance by society and by the healthcare system.

CONCLUSIONS

This study provides evidence to policymakers and health practitioners that investing upstream in well-developed AHT prevention programs, such as PURPLE, not only promote child safety and health, but also translates into avoided costs to society.

Awareness of abusive head trauma in a German population-based sample: implications for prevention

BACKGROUND

Despite efforts to reduce the incidence of abusive head trauma (AHT), incidence rates remain high. One cause is that prevention programs mostly aim to educate mothers of newborns on AHT and infant crying. However, mothers commonly have already a high knowledge and constitute only a minority among identified AHT perpetrators. The hypothesis was that there are great differences in AHT awareness in different subgroups. To assess awareness of AHT, a population-based study was performed.

METHODS

A population-based representative sample of the German population aged >14 years (N = 2510) was assessed in a cross-sectional observational survey. The sample was selected in a random route approach between November 2017 and February 2018.

RESULTS

Overall knowledge of AHT was higher in women (67.9%) than in men (48.8%, p < 0.001). Female gender, having children, higher age, and level of education were predictors for the awareness of AHT. A majority of participants reported to have heard about AHT from the media.

CONCLUSIONS

Awareness of AHT differs significantly within the population. In groups at higher risk to perpetrate AHT, including men, young caregivers, and those with low educational level, awareness of AHT was low. These subgroups should be targeted by tailored education programs for prevention.

Epidemiology of abusive head trauma in West Virginia children <24 months: 2000-2010

BACKGROUND

Few states have published statewide epidemiology of abusive head trauma (AHT).

OBJECTIVE

To examine the statewide epidemiology of AHT in West Virginia (WV), with the primary objective of establishing AHT incidence for comparison to national data, and to use as a baseline for comparison to incidence post-implementation of a statewide AHT prevention program.

PARTICIPANTS AND SETTING

AHT cases in children less than 2 years old were identified from the 3 tertiary pediatric centers in WV.

METHODS

Cases were identified by using ICD-9 codes for initially identifying those with injuries which might be consistent with AHT, followed by medical record review to determine which of these met the criteria for inclusion as a case. Medical examiner data was used to find additional cases of AHT. Using the number of cases identified along with relevant census data, incidence of AHT was calculated.

RESULTS

There were 120 cases of AHT treated in WV hospitals from 2000 to 2010, 100 of which were WV residents. The incidence was 36.1/100,000 children <1 year of age and was 21.9 cases per 100,000 children <2 years of age. Incidence in infants increased during the latter years (2006-2010) of the study to 51.8/100,000 compared to the incidence during 2000-2005, which was 24.0/100,000 (p < .01).

CONCLUSIONS

Compared to US national, state and regional figures, the WV incidence of AHT was among the highest. In addition, the incidence of AHT increased significantly over the study period. Possible factors contributing to the rise in incidence are discussed.

Pediatric Traumatic Brain Injury and Associated Topics: An Overview of Abusive Head Trauma, Nonaccidental Trauma, and Sports Concussions

Pediatric traumatic brain injury (TBI) uniquely affects the pediatric population. Abusive head trauma (AHT) is a subset of severe pediatric TBI usually affecting children in the first year of life. AHT is a form of nonaccidental trauma. Sports-related TBI resulting in concussion is a milder form of TBI affecting older children. Current recommended perioperative management of AHT and sports concussions relies on general pediatric TBI guidelines. Research into more specific pediatric TBI screening and management goals is ongoing. This article reviews the epidemiology, mechanisms, clinical signs, and management of AHT and sports-related concussions.

Feasibility study of the calm baby gently program: An educational baby book intervention on safe practices related to infant crying

BACKGROUND

Abusive head trauma (AHT) is a preventable form of child abuse.

OBJECTIVE

This project used a mixed method design to assess the feasibility of the Calm Baby Gently educational baby book intervention for promoting safe practices related to infant crying in an effort to prevent AHT.

PARTICIPANTS AND SETTING

Three pediatric practices participated between June 2016 and January 2018, including 1045 caregivers who attended their infant's 2-month well-child visit.

METHODS

Pediatric providers gave the educational baby book to caregivers at the 1-month well-child visit. Caregivers completed a survey at the 2-month well-child visit on their use and satisfaction with the book and responses to infant crying. Thematic analysis of qualitative feedback was performed. Responses to infant crying were compared quantitatively between caregivers who had and had not read the book.

RESULTS

Of the 819 caregivers (78%) who received the book, 92% (754) read it, and 51% (421) had another caregiver read it. Caregivers considered the book approachable, understandable, validating, and helpful for improving knowledge and skills related to infant crying. The book was rated more helpful by caregivers of younger age, male gender, and non-white race. Controlling for age, gender, and race, caregivers who read the book were more confident (p = 0.033) and had more knowledge on how to respond appropriately to infant crying (p = 0.019) than caregivers who had not read it.

CONCLUSIONS

Calm Baby Gently is a feasible and well-received AHT prevention program. Randomized controlled trials are needed to better understand its impact on knowledge, behavior, and AHT rates.

Do we get the message through? Difficulties in the prevention of abusive head trauma

Many programs aim to prevent abusive head trauma throughout the USA, Europe, and in many other regions of the world. Most of these programs inform mothers shortly after delivery about the dangers of abusive head trauma. Effectiveness of these programs usually is measured by the increase of knowledge on abusive head trauma. Recent research showed, however that for effective primary prevention, a much broader approach might be necessary. But so far, there is no data that reports the knowledge on key messages on abusive head trauma in the general public as a baseline. We conducted a representative population-based survey on abusive head trauma knowledge in Germany. Whereas the dangers are generally well known, a majority might be ambivalent towards the recommendation to leave a crying infant alone for a few minutes when the caregiver becomes too stressed or frustrated. Furthermore, a majority prefers being informed on abusive head trauma before birth.Conclusion: Future preventive programs should focus on educating adolescents (potential baby sitters) and young adults when they do not yet have children of their own. What is known: • Most programs for primary prevention of abusive head trauma (AHT) focus on mothers shortly after delivery • There are no analyses so far of the quality of education programs in the general public, as educating mothers might not be sufficient to reduce incidence rates What is new: • Our study is the first population-based survey to measure the knowledge on AHT in a representative population sample and to provide the data base for targeted prevention programs. • The introduction of broader prevention programs might be necessary.

How Do Nurses Keep Children Safe From Abuse and Neglect, and Does it Make a Difference? A Scoping Review

OBJECTIVES

To explore the extent of child protection work performed by nurses and identify which interventions hold the strongest evidence for future practice.

DESIGN

This scoping review was guided by Arksey and O'Malley's framework for scoping reviews.

DATA SOURCES

Electronic databases (CINAHL, Medline, Scopus, Web of Science) and grey literature were searched in August 2017. Further studies were identified through manual literature searching.

RESULTS

Forty-one studies from seven countries met the inclusion criteria. The studies showed nurses keep children safe primarily through the prevention of abuse (n = 32), but also through detection of abuse (n = 1) and interventions to mitigate the effects of abuse (n = 8). Nurses' specific interventions most frequently involved post-natal home visiting (n = 20), parent education (n = 10) and assessment and care of children or adolescents following sexual abuse (n = 4). The main findings showed that although nurses did have positive impacts upon some measures of abuse and neglect, results were not consistent across studies. In addition, some studies used indirect measures of abuse and neglect, which may not impact children's experiences of abuse. It is difficult to extrapolate these findings to the broader nursing profession as literature did not accurately represent the range of ways that nurses keep children safe from abuse and neglect.

CONCLUSIONS

This review demonstrated nurses prevent, detect and respond to abuse and neglect in many ways. However, given mixed evidence and absence of some nurse interventions in the literature, further research is needed to represent the range of ways that nurses keep children safe and determine their effectiveness.

Eight-year outcome of implementation of abusive head trauma prevention

Low incidence rates and economic recession have hampered interpretation of educational prevention efforts to reduce abusive head trauma (AHT). Our objective was to determine whether the British Columbia experience implementing a province-wide prevention program reduced AHT hospitalization rates. A 3-dose primary, universal education program (the Period of PURPLE Crying) was implemented through maternal and public health units and assessed by retrospective-prospective surveillance. With parents of all newborn infants born between January 2009 and December 2016 (n = 354,477), nurses discussed crying and shaking while delivering a booklet and DVD during maternity admission (dose 1). Public health nurses reinforced Talking Points by telephone and/or home visits post-discharge (dose 2) and community education was instituted annually (dose 3). During admission, program delivery occurred for 90% of mothers. Fathers were present 74.4% of the time. By 2-4 months, 70.9% of mothers and 50.5% of fathers watched the DVD and/or read the booklet. AHT admissions decreased for <12-month-olds from 10.6 (95% CI: 8.3-13.5) to 7.1 (95% CI: 4.8-10.5) or, for <24-month-olds, from 6.7 (95% CI: 5.4-8.3) to 4.4 (95% CI: 3.1-6.2) cases per 100,000 person-years. Relative risk of admission was 0.67 (95% CI: 0.42-1.07, P = 0.090) and 0.65 (95% CI: 0.43-0.99, P = 0.048) respectively. We conclude that the intervention was associated with a 35% reduction in infant AHT admissions that was significant for <24-month-olds. The results are encouraging that, despite a low initial incidence and economic recession, reductions in AHT may be achievable with a system-wide implementation of a comprehensive parental education prevention program.

Lifetime Cost of Abusive Head Trauma at Ages 0-4, USA

This paper aims to estimate lifetime costs resulting from abusive head trauma (AHT) in the USA and the break-even effectiveness for prevention. A mathematical model incorporated data from Vital Statistics, the Healthcare Cost and Utilization Project Kids' Inpatient Database, and previous studies. Unit costs were derived from published sources. From society's perspective, discounted lifetime cost of an AHT averages $5.7 million (95% CI $3.2-9.2 million) for a death. It averages $2.6 million (95% CI $1.0-2.9 million) for a surviving AHT victim including $224,500 for medical care and related direct costs (2010 USD). The estimated 4824 incident AHT cases in 2010 had an estimated lifetime cost of $13.5 billion (95% CI $5.5-16.2 billion) including $257 million for medical care, $552 million for special education, $322 million for child protective services/criminal justice, $2.0 billion for lost work, and $10.3 billion for lost quality of life. Government sources paid an estimated $1.3 billion. Out-of-pocket benefits of existing prevention programming would exceed its costs if it prevents 2% of cases. When a child survives AHT, providers and caregivers can anticipate a lifetime of potentially costly and life-threatening care needs. Better effectiveness estimates are needed for both broad prevention messaging and intensive prevention targeting high-risk caregivers.

Simulation-based research to improve infant health outcomes: Using the infant simulator to prevent infant shaking

Simulation is a technique that creates a situation or environment to allow persons to experience a representation of a real event for the purpose of practice, learning, evaluation, testing, or to gain understanding of systems or human actions. We will first provide an introduction to simulation in healthcare and describe the two types of simulation-based research (SBR) in the pediatric population. We will then provide an overview of the use of SBR to improve health outcomes for infants in health care settings and to improve parent-child interactions using the infant simulator. Finally, we will discuss previous and future research using simulation to reduce morbidity and mortality from abusive head trauma, the most common cause of traumatic death in infancy.

Potential Opportunities for Prevention or Earlier Diagnosis of Child Physical Abuse in the Inpatient Setting

OBJECTIVES

To compare rates of previous inpatient visits among children hospitalized with child physical abuse (CPA) with controls as well as between individual abuse types.

METHODS

In this study, we used the Pediatric Health Information System administrative database of 44 children's hospitals. Children <6 years of age hospitalized with CPA between January 1, 2011, and September 30, 2015, were identified by discharge codes and propensity matched to accidental injury controls. Rates for previous visit types were calculated per 10 000 months of life. χ2 and Poisson regression were used to compare proportions and rates.

RESULTS

There were 5425 children hospitalized for CPA. Of abuse and accident cases, 13.1% and 13.2% had a previous inpatient visit, respectively. At previous visits, abused children had higher rates of fractures (rate ratio [RR] = 3.0 times; P = .018), head injuries (RR = 3.5 times; P = .005), symptoms concerning for occult abusive head trauma (AHT) (eg, isolated vomiting, seizures, brief resolved unexplained events) (RR = 1.4 times; P = .054), and perinatal conditions (eg, prematurity) (RR = 1.3 times; P = .014) compared with controls. Head injuries and symptoms concerning for occult AHT also more frequently preceded cases of AHT compared with other types of abuse (both P < .001).

CONCLUSIONS

Infants hospitalized with perinatal-related conditions, symptoms concerning for occult AHT, and injuries are inpatient populations who may benefit from abuse prevention efforts and/or risk assessments. Head injuries and symptoms concerning for occult AHT (eg, isolated vomiting, seizures, and brief resolved unexplained events) may represent missed opportunities to diagnose AHT in the inpatient setting; however, this requires further study.
