Assessment of Mothers' Shaking Behavior of their Babies and Related Factors: An Experimental Approach Using an Accelerometer and an Infant Manikin

Background

Our study aimed to investigate the factors associated with mothers' shaking behavior of their babies.

Methods

Sixty-three mothers who stated that they shook their babies (Group B) and 91 mothers who stated that they did not (Group A) among those who applied to or were followed up from the Pediatric Outpatient Clinics of our University Hospital were included. The mothers (with a baby aged 0-30 months) completed the Brief Symptom Inventory (BSI) and psychiatric rating scales measuring attachment styles, empathic tendency, perceived social support, and self-esteem. The severity of the simulated shaking of the mothers was measured by an accelerometer placed on an infant manikin and separately scored on a Numerical Rating Scale by the researchers and an Illustrated Numeric Rating Scale by the mothers.

Results

In group B, babies' crying frequency was higher (P = .008); soothing the babies when they cried was more difficult (P = .019), mothers reported that they were exposed to physical violence more in their childhood (P = .003), BSI hostility scores (P = .004) and BSI-anxiety scores (P = .034) of the mothers were higher when compared with the group A. The age of the babies (P = .002, OR = 1.096), moderate crying frequency (P = .035, OR = 2.900), the mothers' difficulty in soothing their babies (sometimes P = .018, OR = 3.705, often/always P = .014, OR = 7.777), and the mothers' experience of physical violence in childhood (P = .002, OR = 5.674) were found to be factors affecting the shaking behavior.

Conclusion

Clarifying the factors associated with the mothers' shaking behavior of their babies would be helpful in terms of protecting future generations.

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.

Developmental outcomes in abusive head trauma

Abusive head trauma (AHT) is associated with high mortality and poorer outcomes compared to accidental head injuries. The short and long-term developmental outcomes for AHT are not well identified. Variability in outcome measures, small sample sizes, difficulty in measuring domain-specific developmental skills, co-existence of comorbidities, genetic and environmental factors and high attrition rates all contribute to the challenges on providing data in this area. The objective of this article is to review the scientific literature on the developmental outcomes of AHT, highlighting factors that affect outcomes, the available assessment tools, and short and long-term developmental outcomes, recommended follow up, societal costs, and future opportunities for research. Authors searched OVID Medline and PubMed for articles published between 2013 and 2023 using the terms "abuse", "craniocerebral trauma" and "development". Fifty-five records were included for this review. The data shows that injuries sustained from AHT result in a spectrum of outcomes ranging from normal development to death. There are more than 100 outcome assessment tools limiting the ability to compare studies. More than half of patients are left with disabilities post discharge. Gross motor and cognition/academics are the 2 most common domains studied. Advancement in surgical and neurocritical care management has influenced AHT outcomes. Close long-term follow up is recommended to maximize each child's developmental potential, irrespective of the presence of disability at discharge. We suggest that future research should focus on adopting a consistent diagnostic and assessment approach and explore the social environmental factors that can affect recovery.

Multiorgan Dysfunction Syndrome in Abusive and Accidental Pediatric Traumatic Brain Injury

BACKGROUND

Abusive head trauma (AHT) is a mechanism of pediatric traumatic brain injury (TBI) with high morbidity and mortality. Multiorgan dysfunction syndrome (MODS), defined as organ dysfunction in two or more organ systems, is also associated with morbidity and mortality in critically ill children. Our objective was to compare the frequency of MODS and evaluate its association with outcome between AHT and accidental TBI (aTBI).

METHODS

This was a single center, retrospective cohort study including children under 3 years old admitted to the pediatric intensive care unit with nonpenetrating TBI between 2014 and 2021. Presence or absence of MODS on days 1, 3, and 7 using the Pediatric Logistic Organ Dysfunction-2 score and new impairment status (Functional Status Scale score change > 1 compared with preinjury) at hospital discharge (HD), short-term timepoint, and long-term timepoint were abstracted from the electronic health record. Multiple logistic regression was performed to examine the association between MODS and TBI mechanism with new impairment status.

RESULTS

Among 576 children, 215 (37%) had AHT and 361 (63%) had aTBI. More children with AHT had MODS on days 1 (34% vs. 23%, p = 0.003), 3 (28% vs. 6%, p < 0.001), and 7 (17% vs. 3%, p < 0.001) compared with those with aTBI. The most common organ failures were cardiovascular ([AHT] 66% vs. [aTBI] 66%, p = 0.997), neurologic (33% vs. 16%, p < 0.001), and respiratory (34% vs. 15%, p < 0.001). MODS was associated with new impairment in multivariable logistic regression at HD (odds ratio 19.1 [95% confidence interval 9.8-38.6, p < 0.001]), short-term discharge (7.4 [3.7-15.2, p < 0.001]), and long-term discharge (4.3 [2.0-9.4, p < 0.001])]. AHT was also associated with new impairment at HD (3.4 [1.6-7.3, p = 0.001]), short-term discharge (2.5 [1.3-4.7, p = 0.005]), and long-term discharge (2.1 [1.1-4.1, p = 0.036]).

CONCLUSIONS

Abusive head trauma as a mechanism was associated with MODS following TBI. Both AHT mechanism and MODS were associated with new impairment at all time points.

Efficacy of Child Abuse Evaluations for Infants With Possible Subdural Hemorrhage Identified on Cranial Ultrasound Completed for Macrocephaly

Abusive head trauma (AHT) is a significant cause of morbidity and mortality for infants. Determining when to pursue a complete physical abuse evaluation can be difficult, especially for nonspecific findings or when a child appears clinically well. This retrospective study of 7 cases sought to describe the presentation, evaluation, and diagnoses for infants with abnormal subdural collections identified on cranial ultrasound for macrocephaly, and to determine how frequently AHT is diagnosed. The results of this study showed that while each patient presented due to asymptomatic macrocephaly, the extent of the workup varied greatly. In addition, no infants had suspicious injuries for abuse during the initial evaluation or the year following. In summary, among the 7 patients seen for asymptomatic macrocephaly with possible subdural hemorrhage, there were very inconsistent child abuse workups. There needs to be a standardized clinical guideline for this specific patient population involving a child abuse pediatric evaluation.

A Multicenter Study on the Clinical Characteristics and Outcomes Among Children With Moderate to Severe Abusive Head Trauma

INTRODUCTION

We aimed to identify clinical characteristics, risk factors for diagnosis, and describe outcomes among children with AHT.

METHODS

We performed an observational cohort study in tertiary care hospitals from 14 countries across Asia and Ibero-America. We included patients <5 years old who were admitted to participating pediatric intensive care units (PICUs) with moderate to severe traumatic brain injury (TBI). We performed descriptive analysis and multivariable logistic regression for risk factors of AHT.

RESULTS

47 (12%) out of 392 patients were diagnosed with AHT. Compared to those with accidental injuries, children with AHT were more frequently < 2 years old (42, 89.4% vs 133, 38.6%, p < 0.001), more likely to arrive by private transportation (25, 53.2%, vs 88, 25.7%, p < 0.001), but less likely to have multiple injuries (14, 29.8% vs 158, 45.8%, p = 0.038). The AHT group was more likely to suffer subdural hemorrhage (SDH) (39, 83.0% vs 89, 25.8%, p < 0.001), require antiepileptic medications (41, 87.2% vs 209, 60.6%, p < 0.001), and neurosurgical interventions (27, 57.40% vs 143, 41.40%, p = 0.038). Mortality, PICU length of stay, and functional outcomes at 3 months were similar in both groups. In the multivariable logistic regression, age <2 years old (aOR 8.44, 95%CI 3.07-23.2), presence of seizures (aOR 3.43, 95%CI 1.60-7.36), and presence of SDH (aOR 9.58, 95%CI 4.10-22.39) were independently associated with AHT.

CONCLUSIONS

AHT diagnosis represented 12% of our TBI cohort. Overall, children with AHT required more neurosurgical interventions and the use of anti-epileptic medications. Children younger than 2 years and with SDH were independently associated with a diagnosis of AHT.

TYPE OF STUDY

How Antiscience Creates Confusion About the Diagnosis of Abusive Head Trauma

This Viewpoint exposes the antiscience and misinformation used to generate skepticism about abusive head trauma in young children, putting this vulnerable population at risk.

Comparisons of characteristics and outcome between abusive head trauma and non-abusive head trauma in a pediatric intensive care unit

BACKGROUND

Abusive head trauma (AHT) is the leading cause of death in infants with traumatic brain injury (TBI). Early recognition of AHT is important for improving outcomes, but it can be challenging due to its similar presentations with non-abusive head trauma (nAHT). This study aims to compare clinical presentations and outcomes between infants with AHT and nAHT, and to identify the risk factors for poor outcomes of AHT.

METHODS

We retrospectively analyzed infants of TBI in our pediatric intensive care unit from January 2014 to December 2020. Clinical manifestations and outcomes were compared between patients with AHT and nAHT. Risk factors for poor outcomes in AHT patients were also analyzed.

RESULTS

60 patients were enrolled for this analysis, including 18 of AHT (30%) and 42 of nAHT (70%). Compared with those with nAHT, patients with AHT were more likely to have conscious change, seizures, limb weakness, and respiratory failure, but with a fewer incidence of skull fractures. Additionally, clinical outcomes of AHT patients were worse, with more cases undergoing neurosurgery, higher Pediatric Overall Performance Category score at discharge, and more anti-epileptic drug (AED) use after discharge. For AHT patients, conscious change is an independent risk factor for a composite poor outcome of mortality, ventilator dependence, or AED use (OR = 21.9, P = 0.04) CONCLUSION: AHT has a worse outcome than nAHT. Conscious change, seizures and limb weaknesses but not skull fractures are more common in AHT. Conscious change is both an early reminder of AHT and a risk factor for its poor outcomes.

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.

Cerebral hemorrhage caused by shaking adult syndrome? Evidence from biomechanical analysis using 3D motion capture and finite element models

The present study combined three-dimensional (3D) motion capture with finite element simulation to reconstruct a real shaking adult syndrome (SAS) case and further explore the injury biomechanics of SAS. The frequency at which an adult male can shake the head of another person, head-shaking amplitude, and displacement curves was captured by the VICON 3D motion capture system. The captured shaking frequency and shaking curve were loaded on the total human model for safety (THUMS) head to simulate the biomechanical response of brain injury when a head was shaken in anterior-posterior, left-right, and left anterior-right posterior directions at frequencies of 4 Hz (Hz), 5 Hz, 6 Hz, and 7 Hz. The biomechanical response of the head on impact in the anterior, posterior, left, left anterior, and right posterior directions at the equivalent velocity of 6 Hz shaking was simulated. The violent shaking frequency of the adult male was 3.2-6.8 Hz; head shaking at these frequencies could result in serious cerebral injuries. SAS-related injuries have obvious directionality, and sagittal shaking can easily cause brain injuries. There was no significant difference between the brain injuries caused by shaking in the simulated frequency range (4-7 Hz). Impact and shaking at an equivalent velocity could cause brain injuries, though SAS more commonly occurred due to the cumulative deformation of brain tissue. Biomechanical studies of SAS should play a positive role in improving the accuracy of forensic identification and reducing this form of abuse and torture in detention or places of imprisonment.

Magnetic Resonance Imaging Findings in Infants with Severe Traumatic Brain Injury and Associations with Abusive Head Trauma

Young children with severe traumatic brain injury (TBI) have frequently been excluded from studies due to age and/or mechanism of injury. Magnetic resonance imaging (MRI) is now frequently being utilized to detect parenchymal injuries and early cerebral edema. We sought to assess MRI findings in infants with severe TBI, and to determine the association between specific MRI findings and mechanisms of injury, including abusive head trauma (AHT). MRI scans performed within the first 30 days after injury were collected and coded according to NIH/NINDS Common Data Elements (CDEs) for Neuroimaging in subjects age < 2 years old with severe TBI enrolled in the Approaches and Decisions in Acute Pediatric Traumatic Brain Injury Trial. Demographics and injury characteristics were analyzed. A total of 81 children were included from ADAPT sites with MRI scans. Median age was 0.77 years and 57% were male. Most common MRI finding was ischemia, present in 57/81 subjects (70%), in a median of 7 brain regions per subject. Contusion 46/81 (57%) and diffuse axonal injury (DAI) 36/81 (44.4%) subjects followed. Children were dichotomized based on likelihood of AHT with 43/81 subjects classified as AHT. Ischemia was found to be significantly associated with AHT (p = 0.001) and “inflicted” injury mechanism (p = 0.0003). In conclusion, the most common intracerebral injury seen on MRI of infants with severe TBI was ischemia, followed by contusion and DAI. Ischemia was associated with AHT, and ischemia affecting > 4 brain regions was predictive of AHT.

Injuries Associated With Subsequent Child Maltreatment Diagnosis: By Age, Race, Gender, and Medicaid Status

This study examined injuries that may precede a child maltreatment (CM) diagnosis, by age, race/ethnicity, gender, and Medicaid status using a retrospective case-control design among child members of a large integrated healthcare system (N = 9152 participants, n = 4576 case). Injury categories based on diagnosis codes from medical visits were bruising, fractures, lacerations, head injury, burns, falls, and unspecified injury. Results showed that all injury categories were significant predictors of a subsequent CM diagnosis, but only for children < 3 years old. Specifically, fracture and head injury were the highest risk for a subsequent CM diagnosis. All injury types were significant predictors of maltreatment diagnosis for Hispanic children < 3 years, which was not the case for the other race/ethnicities. Overall, these findings suggest that all types of injury within these specific categories should have a more thorough assessment for possible abuse for children under 3 years. This work can inform the development of clinical decision support tools to aid healthcare providers in detecting abusive injuries.

The Relationship Between Temperature and Temporal Patterns and Incidence of Abusive Head Trauma in a Midwest Region Hospital

Background: Abusive head trauma (AHT) is a leading cause of death and disability in children and one of the most lethal forms of child abuse. Most known risk factors for AHT pertain to the infant's caregiver and limited research has assessed external influences beyond the familial or caregiver/infant dyad. Objective: Our primary objective was to determine if temperature patterns are associated with AHT events. Secondary outcomes included associations between AHT and specific days of the week, months, or seasons. Methods: This was a retrospective review of 198 patients under 24 months old who were diagnosed with AHT at Saint Louis Children's Hospital. Demographic information was obtained from the medical record for each patient. For each AHT incident, the date and zip code of the incident were recorded. Temperature on the date of incident was identified using the Midwestern Regional Climate Center (MRCC). Chi square tests were utilized to calculate differences in cases per year as well as temperature and seasonal variation. Results: Temperature was not associated with a statistically significant increase in cases of AHT. There was an increase in cases as temperatures rose, but no statistically significant associations between incidence of AHT and day of the week, month, or season. Conclusion: Our study suggests no significant association between AHT incidence and temperature or temporal patterns in this Midwest hospital.

Diagnosis of Abusive Head Trauma : Neurosurgical Perspective

Abusive head trauma (AHT) is the most severe form of physical abuse in children. Such injury involves traumatic damage to the head and/or spine of infants and young children. The term AHT was introduced to include a wider range of injury mechanisms, such as intentional direct blow, throw, and even penetrating trauma by perpetuator(s). Currently, it is recommended to replace the former term, shaken baby syndrome, which implicates shaking as the only mechanism, with AHT to include diverse clinical and radiological manifestations. The consequences of AHT cause devastating medical, social and financial burdens on families, communities, and victims. The potential harm of AHT to the developing brain and spinal cord of the victims is tremendous. Many studies have reported that the adverse effects of AHT are various and serious, such as blindness, mental retardation, physical limitation of daily activities and even psychological problems. Therefore, appropriate vigilance for the early recognition and diagnosis of AHT is highly recommended to stop and prevent further injuries. The aim of this review is to summarize the relevant evidence concerning the early recognition and diagnosis of AHT. To recognize this severe type of child abuse early, all health care providers maintain a high index of suspicion and vigilance. Such suspicion can be initiated with careful and thorough history taking and physical examinations. Previously developed clinical prediction rules can be helpful for decision-making regarding starting an investigation when considering meaningful findings. Even the combination of biochemical markers may be useful to predict AHT. For a more confirmative evaluation, neuroradiological imaging is required to find AHT-specific findings. Moreover, timely consultation with ophthalmologists is needed to find a very specific finding, retinal hemorrhage.

A National Analysis of Ophthalmic Features and Mortality in Abusive Head Trauma

IMPORTANCE

It is important to recognize presenting features and factors associated with mortality in abusive head trauma (AHT) owing to the severity of the diagnosis and the necessity for prompt action.

OBJECTIVE

To describe the prevalence and economic burden of AHT and identify factors associated with mortality.

DESIGN, SETTING, AND PARTICIPANTS

This retrospective, cross-sectional study used the Nationwide Emergency Department Sample database to identify all emergency department visits in the US for patients younger than 5 years with a primary diagnosis of abusive head trauma between January 1, 2006, and December 31, 2018. This study was conducted in 2021.

MAIN OUTCOMES AND MEASURES

Prevalence, demographic characteristics, clinical characteristics, mortality, and economic burden associated with AHT. Weighted national estimates were calculated using sampling weights provided in the Nationwide Emergency Department Sample database.

RESULTS

From 2006 to 2018, there were an estimated 12 287 cases of emergency department visits in the US for patients younger than 5 years with a primary diagnosis of AHT. The estimated number of AHT cases decreased by 672 (95% CI, 403-940; P < .001) from 2006 to 2018. The incidence decreased by 6.7% each year (incidence rate ratio, 0.93; 95% CI, 0.93-0.94; P < .001) between 2006 and 2018. During the course of a hospital visit, 646 patients (5.3%) died. The majority of patients with a diagnosis of AHT were younger than 1 year (n = 7046; 57.3%), were male (n = 7268; 59.2%) and had Medicaid insurance (n = 8585; 70.0%). After controlling for demographic characteristics, factors associated with increased mortality were age greater than 1 year (odds ratio [OR], 2.45; 95% CI, 1.50-3.99; P < .001), first or second income quartile (OR, 1.78; 95% CI, 1.08-2.91; P = .02), midwestern United States (OR, 2.04; 95% CI, 1.04-4.00; P = .04), level 1 trauma center (OR, 2.69; 95% CI, 1.07-6.75; P = .04), orbital fracture (OR, 15.38; 95% CI, 2.41-98.18; P = .004), cerebral edema (OR, 8.49; 95% CI, 5.57-12.93; P < .001), intracranial hemorrhage (OR, 4.27; 95% CI, 1.71-10.67; P = .002), hypoxic ischemic brain injury (OR, 4.16; 95% CI, 2.13-8.10; P < .001), skull fractures (OR, 3.20; 95% CI, 1.76-5.82; P < .001), subarachnoid hemorrhage (OR, 2.43; 95% CI, 1.22-4.83; P = .01), retinal hemorrhage (OR, 2.17; 95% CI, 1.40-3.38; P < .001), and subdural hemorrhage (OR, 2.05; 95% CI, 1.05-3.98; P = .04).

CONCLUSIONS AND RELEVANCE

This study's findings suggest that health care disparities may be present in the treatment of AHT. Recognizing factors suggested in this investigation to be associated with higher mortality, public health efforts should be targeted toward low-income areas and in the midwestern United States.

Ocular Injuries in Pediatric Patients Admitted With Abusive Head Trauma

BACKGROUND

Pediatric abusive head trauma (AHT) refers to head injury from intentional blunt force or violent shaking in children aged five years or less. We sought to evaluate the epidemiology of ocular injuries in AHT.

METHODS

This retrospective analysis of the National Trauma Data Bank (2008 to 2014) identified children aged five years or less with AHT and ocular injuries using ICD-9-CM codes. Demographic data, types of ocular and nonocular/head injuries, geographic location, length of hospital admission, injury severity, and Glasgow Coma scores were tabulated and analyzed.

RESULTS

A total of 10,545 children were admitted with AHT, and 2550 (24.2%) had associated ocular injuries; 58.7% were female. The mean age was 0.5 (±1.0) years. Most (85.7%) were aged one year or less. Common ocular injuries included contusion of eye/adnexa (73.7%) and retinal edema (59.3%), and common head injuries were subdural hemorrhage (SDH) (72.8%) and subarachnoid hemorrhage (22.9%). Retinal hemorrhages occurred in 5.3%. About 42.8% of children had injury severity scores greater than 24 (very severe), and the mortality rate was 19.2%. Children aged one year or less had the greatest odds of retinal hemorrhages (odds ratio [OR] = 2.44; P = 0.008) and SDH (OR = 1.55; P < 0.001), and the two- to three-year-old group had the greatest odds of contusions (OR = 1.68; P = 0.001), intracerebral hemorrhages (OR = 1.55; P = 0.002), and mortality (OR = 1.78; P < 0.001). For all ages, SDH occurred most frequently with retinal edema compared with other ocular injuries (OR = 2.25; P < 0.001).

CONCLUSIONS AND RELEVANCE

Ocular injuries varied with age and were variably associated with nonocular injury. The youngest group was most frequently affected; however, the two- to three-year-old group was most likely to succumb to injuries.

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.

Effectiveness of Educational Materials Designed to Improve Knowledge Regarding Crying and Shaken Baby Syndrome in Mothers of Hispanic Population

Background: Caregiver frustration with inconsolable crying is a commonly cited antecedent factor of Abusive head trauma (AHT) in infants. Objective: To assess the effectiveness of an educational intervention to improve patients' knowledge of normal crying patterns in infants and the implications of AHT among women of Hispanic population. Methods: The Period of PURPLE Crying program was piloted as part of Centering Prenatal Care at an outpatient clinic site in the Harris County Health Department system, which cares for a primarily underserved and Spanish speaking population. Educational material and direct counseling were delivered by the clinician. Demographic data was collected and a pre- and post-test survey was administrated to assess participant's knowledge and behavior. Results: Between April 2017 and April 2018, 63 Hispanic women were included in this study. Prior to implementation of the educational tool, most of the survey questions were answered incorrectly. After the intervention, knowledge regarding normal infant crying patterns was significantly improved in all questions. However, knowledge gaps persisted especially in relation to the adequacy of parents' ability to soothe a crying infant and normalcy of excessive crying. Conclusions: The educational curriculum was an effective tool for improving knowledge about normal infant crying patterns in Hispanic mothers.

Epidemiology of Abusive Head Trauma Among Children in Saudi Arabia

BACKGROUND AND OBJECTIVES

To examine abusive head trauma (AHT) trends using data obtained from hospital-based child protection centers (CPCs) and the distribution of age in months among young children in Saudi Arabia.

METHODS

A retrospective study was conducted that includes data obtained from 58 hospital-based CPCs in all 13 regions of Saudi Arabia registered in the National Family Safety Registry from 2010 to 2020. AHT cases (n=106) were identified for inclusion in the registry by a daily review of the emergency department logbooks.

RESULTS

Over the 11-year period, there was a sharp increase in the number of cases, specifically after 2014, from seven cases per year in 2010 to 16 cases in 2020. AHT affects predominantly children aged 0-12 months (72.6%), followed by 13-24 months (17.9%), 25-36 months (3.8%), 37-48 months (3.8%), and 49-60 months (1.9%). Victims were characterized by a predominance of crying infants (23.6%), past history of abuse (13.2%), a child's chronic disease and disability (7.6%), and prematurity (2.8%).

CONCLUSION

Different training and educational programs need to be performed to raise awareness of AHT. Enacting the pediatrician's mandatory reporting law will improve the rate of reporting cases.

Fatal intracranial hemorrhage due to infantile acute lymphoblastic leukemia mimicking abusive head trauma

We report the case of a 2-month-old infant who was found moribund in her crib. Postmortem computed tomography (PMCT) was performed before autopsy. As the baby had a severe subdural hematoma, retinal hemorrhage, and encephalopathy on PMCT, abusive head trauma (AHT) was tentatively diagnosed. At autopsy, no scalp hemorrhages or skull fractures were found; however, the classic triad of AHT was present, mainly on the right side. Additionally, there was dark red discoloration around the heart, and the liver, spleen, and pancreas were enlarged. Peripheral blood was macroscopically cloudy with marked leukocytosis. After careful histological examination, B-cell precursor acute lymphoblastic leukemia (ALL) was diagnosed. All the macroscopic lesions could be attributed to ALL. The manner of death was natural. To the best of our knowledge, this is the first report of infantile ALL mimicking AHT on PMCT images. This case demonstrates the importance of a comprehensive systematic approach to considering differential diagnosis when PMCT shows multiple intracranial hemorrhages suggestive of AHT in an infant.

Trends in shaken baby syndrome diagnosis codes among young children hospitalized for abuse

Objective

To investigate national trends of SBS diagnosis codes and how trends varied among patient and hospital characteristics.

Methods

We examined possible SBS, confirmed SBS, and non-SBS abuse diagnosis codes among children age three and younger who were hospitalized for abuse between 1998 and 2014 using a secondary analysis of the National Inpatient Sample, the largest US all-payer inpatient care database (N = 66,854). A baseline category logit model was used based on a quasi-likelihood approach (QIC) with an independent working correlation structure.

Results

The rate (per 100,000 census population of children age 3 and younger) of confirmed and possible SBS diagnosis codes was 5.4 (± 0.3) between 1998 and 2014, whereas the rate of non-SBS abuse was 19.6 (± 1.0). The rate of confirmed SBS diagnosis codes increased from 3.8 (± 0.3) in 1998 to 5.1 (± 0.9) in 2005, and decreased to 1.3 (± 0.2) in 2014. Possible SBS diagnosis codes were 0.6 (± 0.2) in 1998, increasing to 2.4 (± 0.4) in 2014. Confirmed SBS diagnosis codes have declined since 2002, while possible SBS diagnosis codes have increased. All abuse types were more frequent among infants, males, children from low-income homes, and urban teaching hospitals.

Conclusions

We investigated seventeen-year trends of SBS diagnosis codes among young children hospitalized for abuse. The discrepancy between trends in possible and confirmed SBS diagnosis codes suggests differences in norms for utilizing SBS diagnosis codes, which has implications for which hospital admissions are coded as AHT. Future research should investigate processes for using SBS diagnosis codes and whether all codes associated with abusive head injuries in young children are classified as AHT. Our findings also highlight the relativity defining and applying SBS diagnosis codes to children admitted to the hospital for shaking injuries. Medical professionals find utility in using SBS diagnosis codes, though may be more apt to apply codes related to possible SBS diagnosis codes in children presenting with abusive head injuries. Clarifying norms for SBS diagnosis codes and refining definitions for AHT diagnosis will ensure that young children presenting with, and coded for, abusive head injuries are included in overall counts of AHT based on secondary data of diagnosis codes. This baseline data, an essential component of child abuse surveillance, will enable ongoing efforts to track, prevent, and reduce child abuse.

Risk Factors and Outcomes After a Brief Resolved Unexplained Event: A Multicenter Study

BACKGROUND

The accuracy of the risk criteria for brief resolved unexplained events (BRUEs) from the American Academy of Pediatrics (AAP) is unknown. We sought to evaluate if AAP risk criteria and event characteristics predict BRUE outcomes.

METHODS

This retrospective cohort included infants <1 year of age evaluated in the emergency departments (EDs) of 15 pediatric and community hospitals for a BRUE between October 1, 2015, and September 30, 2018. A multivariable regression model was used to evaluate the association of AAP risk factors and event characteristics with risk for event recurrence, revisits, and serious diagnoses explaining the BRUE.

RESULTS

Of 2036 patients presenting with a BRUE, 87% had at least 1 AAP higher-risk factor. Revisits occurred in 6.9% of ED and 10.7% of hospital discharges. A serious diagnosis was made in 4.0% (82) of cases; 45% (37) of these diagnoses were identified after the index visit. The most common serious diagnoses included seizures (1.1% [23]) and airway abnormalities (0.64% [13]). Risk is increased for a serious underlying diagnosis for patients discharged from the ED with a history of a similar event, an event duration >1 minute, an abnormal medical history, and an altered responsiveness (P < .05). AAP risk criteria for all outcomes had a negative predictive value of 90% and a positive predictive value of 23%.

CONCLUSIONS

AAP BRUE risk criteria are used to accurately identify patients at low risk for event recurrence, readmission, and a serious underlying diagnosis; however, their use results in the inaccurate identification of many patients as higher risk. This is likely because many AAP risk factors, such as age, are not associated with these outcomes.

Implementation of iPads to Increase Compliance With Delivery of New Parent Education in the Mother-Baby Unit: Retrospective Study

BACKGROUND

Abusive head trauma (AHT) is a serious health problem affecting more than 3000 infants annually in the United States. The American Academy of Pediatrics and the Centers for Disease Control and Prevention (CDC) recommend that health care providers counsel new parents about the dangers of AHT. Previous studies demonstrate that parental education is effective at reducing AHT events. South Carolina law requires hospitals to offer all new parents with the opportunity to watch an educational video about AHT. This mandate is addressed in different ways at the several delivery centers within a large South Carolina health care system with a range of viewing methods utilized, from DVD players to mobile workstations to personal devices. Frequent technical barriers and workflow inefficiencies resulted in low rates of compliance with this mandate at several campuses. To improve compliance of parent viewing of this educational video, the health care system standardized video viewing protocol across all campuses by implementing the use of iPads for parental education. Existing literature suggests that patient education can be improved in the hospital setting by utilizing tablet computers, but our literature search identified a gap in research around the education of parents and caregivers during hospitalization for childbirth. We used the implementation of an iPad-based parental education delivery protocol to evaluate whether tablet computers can improve compliance with delivering new parent education in the hospital setting.

OBJECTIVE

The objective of this study was to evaluate whether the standardized use of iPads to deliver education in the mother-baby unit resulted in improved rates of parents' acceptance of the opportunity to view an educational video about AHT.

METHODS

We interviewed physicians and nurses to determine what previous protocols were in place to educate new parents before a standardized iPad-based protocol was implemented across 6 campuses of a large South Carolina health care system. A retrospective study was conducted by review of 5231 records from across the 6 campuses to determine the pre- and postintervention compliance rates of viewing the AHT educational video by parents in the mother-baby unit.

RESULTS

Compliance increased overall (P<.001) across sites from an average of 41.93% (SD 46.24) to 99.73% (SD 0.26) (φ=0.510). As much as 4 of 6 locations saw a significant increase in compliance rates after introducing the iPad intervention (P<.001). The remaining 2 locations that showed no significant difference (P>.05) had very high rates of preintervention compliance.

CONCLUSIONS

Following the implementation of a standardized iPad-based protocol to deliver new parent education, there was a significant improvement in the percentage of new parents who viewed an educational video about AHT in the mother-baby unit. Based on these results, other health care providers should consider iPads to be a feasible and effective method for delivering hospital-based education to families in the mother-baby unit.

Increased proportion of physical child abuse injuries at a level I pediatric trauma center during the Covid-19 pandemic

BACKGROUND AND OBJECTIVES

The Covid-19 pandemic has forced mass closures of childcare facilities and schools. While these measures are necessary to slow virus transmission, little is known regarding the secondary health consequences of social distancing. The purpose of this study is to assess the proportion of injuries secondary to physical child abuse (PCA) at a level I pediatric trauma center during the Covid-19 pandemic.

METHODS

A retrospective review of patients at our center was conducted to identify injuries caused by PCA in the month following the statewide closure of childcare facilities in Maryland. The proportion of PCA patients treated during the Covid-19 era were compared to the corresponding period in the preceding two years by Fisher's exact test. Demographics, injury profiles, and outcomes were described for each period.

RESULTS

Eight patients with PCA injuries were treated during the Covid-19 period (13 % of total trauma patients), compared to four in 2019 (4 %, p < 0.05) and three in 2018 (3 %, p < 0.05). The median age of patients in the Covid-19 period was 11.5 months (IQR 6.8-24.5). Most patients were black (75 %) with public health insurance (75 %). All injuries were caused by blunt trauma, resulting in scalp/face contusions (63 %), skull fractures (50 %), intracranial hemorrhage (38 %), and long bone fractures (25 %).

CONCLUSIONS

There was an increase in the proportion of traumatic injuries caused by physical child abuse at our center during the Covid-19 pandemic. Strategies to mitigate this secondary effect of social distancing should be thoughtfully implemented.

Abusive head trauma: Canadian and global perspectives

Canada has come a long way since Dr. C. Henry Kempe first described battered-child syndrome in 1962. The year 1999 was crucial in Canada's battle against shaken baby syndrome/abusive head trauma (SBS/AHT), when the first national conference on the topic was held in Saskatoon. This was followed by the issuance of a national statement and multidisciplinary guidelines, recently updated in 2020. Incidence of AHT in Canada is similar to that found in population-based studies from Switzerland and New Zealand. The mainstay of prevention of AHT in Canada is education of parents and caregivers with respect to their response to infant crying. Population-based data for global incidence of AHT are lacking, largely because of social and cultural differences contributing to poor understanding of AHT as a medico-legal entity. India faces a distinct challenge in the battle against female feticide and infanticide.

Abusive Head Trauma in Day Care Centers

BACKGROUND

Abusive head trauma (AHT) warrants particular attention in terms of prevention. One of the key questions asked is how often AHT occurs in infant day care centers compared with private parental or nonparental homes. To investigate this, we studied the caretaking arrangement and child's location at the time of injury in a cohort of cases involving AHT from the courts.

METHODS

This multicenter retrospective study covering an 18-year period included all medical and court records of 323 children (2.5 months to 3 years) with AHT, confirmed by the authors acting as medical experts. All markers for abuse and forensic written reports were analyzed by using a standardized data collection tool. The usual child care arrangement and the child's location at the time of injury were noted. The percentage of day care centers found in the study was compared to the expected rate in the French population (19.5%) by using the χ² test.

RESULTS

In 317 AHT cases (98.5%), the assault occurred in a private home (4 in other indoor settings and 1 with missing data). In only 1 case, shaking occurred in a day care center when the nurse was alone with the infant for a few minutes. In 317 cases (98.5%), the usual child care arrangement was by a single adult in charge of 1 or more children.

CONCLUSIONS

The fact that AHT is an unusual occurrence in day care centers could help social service agencies make decisions in terms of prevention. Recent government policies regarding stay-at-home orders during a pandemic have given this issue new relevance.

Identification of Abusive Head Trauma in High-Risk Infants: A Cost-Effectiveness Analysis

OBJECTIVES

To evaluate the cost-effectiveness of abusive head trauma detection strategies in emergency department settings with and without rapid magnetic resonance imaging (rMRI) availability.

STUDY DESIGN

A Markov decision model estimated outcomes in well-appearing infants with high-risk chief complaints. In an emergency department without rMRI, we considered 3 strategies: clinical judgment, universal head computed tomography (CT) scan, or the Pittsburgh Infant Brain Injury Score (PIBIS) with a CT scan. In an emergency department with rMRI for brain availability, we considered additional strategies: universal rMRI, universal rMRI with a CT scan, PIBIS with rMRI, and PIBIS with rMRI followed by a CT scan. Correct diagnosis eliminated future risk; missed abusive head trauma led to reinjury risk with associated poor outcomes. Cohorts were followed for 1 year from a healthcare perspective. One-way and probabilistic sensitivity analyses were performed. The main outcomes evaluated in this study were abusive head trauma correctly identified and incremental cost per quality-adjusted life-year.

RESULTS

Without rMRI availability, PIBIS followed by a CT scan was the most cost-effective strategy. Results were sensitive to variation of CT scan-induced cancer parameters and abusive head trauma prevalence. When rMRI was available, universal rMRI followed by a confirmatory CT scan cost $25 791 to gain 1 additional quality-adjusted life-year compared with PIBIS followed by rMRI with a confirmatory CT scan. In both models, clinical judgement was less effective than alternative strategies.

CONCLUSIONS

By applying CT scans to a more targeted population, PIBIS decreases radiation exposure and is more effective for the identification of abusive head trauma compared with clinical judgment. When rMRI is available, universal rMRI with a CT scan is more effective than PIBIS and is economically favorable.

Health and public health approach to ending child abuse and neglect

The 30^th anniversary of the United Nations Convention on the Rights of the Child provides an opportunity to reflect on whether the approaches to date in dealing with child abuse and neglect (CAN) have been successful. Initial responsibility in most countries to address CAN has been given to Child Protective Services Agencies. Recently, there have been calls for CPS to take a Public Health Approach in their practice. This paper discusses the potential positive and unintended problems that such a shift in approach might entail.

Abusive Head Traumas in 4 Infants

Pediatric abusive head trauma (AHT) is a serious, repeated child abuse that causes grave brain damage. In Korea, AHT cases have been reported rarely, especially infants. We present 4 cases of AHT in infants diagnosed in our institution during last 2 years. We collected the demographic data, ophthalmologic examination, imaging study, and outcomes. The mean age was 7.2 months, and 2 infants were girls and the others were boys. All four were admitted with no history of head trauma, and among them 2 patients presented with an episode of seizure and respiratory arrest with no history of head trauma. The initial mental status was semi-coma in 3 cases, and stupor in 1 case. There were multiple retinal hemorrhages in both eyes in 2 cases; one had multiple old fractures on the extremities and another child showed multiple skull fractures. All patients underwent emergent surgery for acute bilateral subdural hemorrhages; 3 had craniotomy and another had burr-hole drainage. Two children expired and the other 2 are in vegetative status. The AHT has recently become more frequent in Korea so that neurosurgeons must alert AHT even in infants with head trauma.

Child Abuse in Times of Crises: Lessons Learned

The COVID-19 pandemic has created conditions which heighten risk for child abuse. As key players in times of crisis, pediatric emergency medicine providers must be equipped with the tools to recognize, respond to, and mitigate risk of child abuse. An exploration of the scientific literature, stakeholder organization reports and lay press was undertaken to understand the impact of large-scale U.S. crises, including infectious disease, financial downturn, natural disaster, and violence, on child abuse risk and inform prevention strategies. Review of the literature suggests a relationship between crises and child abuse risk, though gaps in the research remain. We outline the role of pediatric emergency medicine providers in partnering with communities in organizing and advocating for systems that better protect children and strengthen families.

More data, more questions: No simple answer about which children should undergo screening neuroimaging for clinically occult abusive head trauma

Abusive head trauma (AHT) is the leading cause of fatal child physical abuse. Victims may initially present with clinically occult AHT without overt signs of head trauma or with only subtle, nonspecific symptoms, which can make timely recognition of AHT challenging. Research has shown missed opportunities for early detection of AHT in the medical setting are common and can lead to repeated injury. Neuroimaging is needed to diagnose clinically occult AHT but is not without risk. Researchers have worked to understand the yield of neuroimaging in detection of clinically occult AHT and to identify risk factors, yet findings have varied widely across studies. Identifying which children undergoing physical abuse evaluations are at highest risk of clinically occult AHT is key to development of evidence-based imaging decision support tools for clinicians. Here we discuss the recent literature, identify potential reasons for variation across studies, and offer opportunities for future research.

Incidence and characteristics of paediatric abusive head trauma in Taiwan, 2006-2015: a nationwide population-based study

OBJECTIVES

To examine the incidence rate and characteristics of paediatric abusive head trauma (PAHT) among children under age 5 years in Taiwan.

METHODS

The International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) was used to identify broad and narrow definitions of children aged under 5 years with PAHT from 2006 to 2015 in Taiwan using a representative national insurance research database. Medical resource utilisation was also analysed. Incidence rates per 100 000 person-years were calculated and presented with 95% CI. Joinpoint regression analysis was used to detect the changes in trends and calculate the annual percentage change in PAHT incidence over time.

RESULTS

From 2006 to 2015, 479 (narrow definition) and 538 (broad definition) PAHT cases were identified. Incidence rates of PAHT by narrow and broad definitions among children under 1 year of age (18.7/100 000 and 20.0/100 000) were nearly 10-fold or 20-fold higher than for children aged 1-2 (1.7/100 000 and 2.1/100 000) and 3-5 (0.9/100 000 and 1.2/100 000) years. The PAHT incidence significantly increased since 2012, with trends varying by age and gender. Our results suggest that over 40% of the children with PAHT experienced serious injury and nearly 13% were fatal cases. For 87% (n=57) of fatal cases, this was their first ever hospitalisation. The number of fatal cases among infants was fourfold higher than that of children aged 1-5 years.

CONCLUSIONS

This study provides a robust national estimate of PAHT and identifies infants as the most vulnerable group for PAHT in Taiwan. Education to enhance healthcare profession's sensitivity and competence for the early identification and diagnosis of PAHT is critical.

The Presence of Anemia in Children with Abusive Head Trauma

OBJECTIVES

To evaluate the incidence of anemia in patients with abusive head trauma (AHT), noninflicted traumatic brain injury (TBI), and physical abuse without AHT and the effect of anemia on outcome.

STUDY DESIGN

In a retrospective, single-center cohort study, we included children under the age of 3 years diagnosed with either AHT (n = 75), noninflicted TBI (n = 77), or physical abuse without AHT (n = 60) between January 1, 2014, and December 31, 2016. Neuroimaging was prospectively analyzed by pediatric neuroradiologists. Primary outcome was anemia at hospital presentation. Secondary outcomes included unfavorable outcome at hospital discharge, defined as a Glasgow Outcome Scale between 1 and 3, and intracranial hemorrhage (ICH) volume.

RESULTS

Patients with AHT had a higher rate of anemia on presentation (47.3%) vs noninflicted TBI (15.6%) and physical abuse without AHT (10%) (P < .001). Patients with AHT had larger ICH volumes (33.3 mL [10.1-76.4 mL] vs 1.5 mL [0.6-5.2 mL] ; P < .001) and greater ICH/total brain volume percentages than patients with noninflicted TBI (4.6% [1.4-8.2 %] vs 0.2% [0.1-0.7%]; P < .001). Anemia was associated with AHT (OR, 4.7; 95% CI, 2.2-10.2) and larger ICH/total brain volume percentage (OR, 1.1; 95% CI, 1.1-1.2) in univariate analysis. Unfavorable outcome at hospital discharge was associated with anemia (OR, 4.4; 95% CI, 1.6-12.6) in univariate analysis, but not after controlling for covariates.

CONCLUSIONS

Patients with AHT were more likely to present to the hospital with anemia and increased traumatic ICH volume than patients with noninflicted TBI or physical abuse without AHT. Children with anemia and AHT may be at increased risk for an unfavorable outcome.

Differences in Incidence and Case Fatality of Abusive Head Trauma

BACKGROUND

Abusive head trauma (AHT) in children older than 1 and younger than 5 years old is thought uncommon and rarely studied.

OBJECTIVE

This study estimates national incidence and case fatality rate of abusive head trauma (AHT), and evaluates differences by age, sex, race, and region, with a focus on children of 2-4 years.

PARTICIPANTS AND SETTING

Hospital discharges were extracted from The Healthcare Cost and Utilization Project's Kids' Inpatient Database from 2000, 2003, 2006, 2009, and 2012 using the CDC's narrow definition of AHT.

METHODS

Survey-weighted chi-square tests were used to assess differences in incidence and case fatality rates.

RESULTS

The average annual incidence per 100,000 children was highest in <1 year-olds (27), followed by age 1 (4), age 2 (3), and age 3-4 (1). Average annual incidence varied significantly by sex (p = 0.0001), race (p < 0.0001), and region (p = 0.0002) within each age category. The average annual case fatality rate increased significantly with age, with a rate of 0.10 among children age <1 year, 0.15 for age 1, 0.23 for age 2, and 0.20 for age 3-4 years. The average annual case fatality rate was higher in the South (0.12) than West (0.10), Midwest (0.09), and Northeast (0.08) among children <1 year of age.

CONCLUSIONS

Black and Hispanic children and hospitals in the Midwest experienced higher incidence of AHT than White children and Northeast hospitals, respectively, especially in cases <1 year of age. Case fatality rates increased significantly with age, and the South experienced the highest rates for infants <1 year.

Age-related mortality in abusive head trauma

BACKGROUND

Abusive head trauma (AHT) peaks during early infancy and decreases in toddler years. Infants and toddlers experience different injuries, possibly impacting the risk of mortality. We aimed to evaluate the association of age with mortality.

METHODS

We conducted a retrospective study of AHT hospitalizations in 2000, 2003, 2006, 2009, and 2012 from the Kid's Inpatient Claims Database. An accidental head trauma cohort was included to hypothesize that the association between age and mortality is unique to abuse. A nested multivariable logistic regression was used to perform the analysis.

RESULTS

Children aged 2 years to 4 years experienced higher mortality than those younger than 2 years (22% vs. 10%, p < 0.0001; adjusted odds ratio [OR], 1.6; 95% confidence interval [CI], 1.1-2.2). The presence of subarachnoid hemorrhage (OR, 1.9; 95% CI, 1.3-2.9), cerebral edema (OR, 4.0; 95% CI, 2.9-5.4), and retinal hemorrhage (OR, 1.9; 95% CI, 1.5-2.5) were associated with an increase risk in mortality. Children younger than 2 years experienced more fractures and hemorrhage (subdural, subarachnoid, retinal) while children aged 2 years to 4 years encountered more internal injuries and cerebral edema.In children with accidental head trauma, those aged 2 years to 4 years have a lower mortality compared with those younger than 2 years (OR, 0.4; 95% CI, 0.3-0.6). Among children younger than 2 years, AHT and accidental trauma had comparable risk of mortality (OR, 0.9; 95% CI, 0.6-1.3). However, among those aged 22 years to 4 years, AHT had a higher risk of mortality than accidental trauma (OR, 3.3; 95% CI, 2.1-5.1).

CONCLUSION

There is a considerable risk of mortality associated with age at diagnosis in children with AHT.Children younger than 2 years and those aged 2 years to 4 years present with different types of injuries. The high risk of mortality in the children aged 2 years to 4 years is unique to AHT. Efforts should be made to increase awareness about the risk of mortality and identify factors that can aide in a timely accurate diagnosis.

Incidence and Risk Factors for Abusive Head Trauma: A Population-Based Study

Previous studies on Abusive Head Trauma (AHT) suggest incidence may vary by geographic location and there is limited information regarding population-based risk factors on this form of child maltreatment. This study provides new knowledge regarding these two aspects using the population of the US state of Washington born between 1999 and 2013. We used a linked administrative dataset comprised of birth, hospital discharge, child protective services (CPS) and death records to identify the scale and risk factors for AHT for the state population using quantitative survival methods. We identified AHT using diagnostic codes in hospital discharge records defined by the US Centers for Disease Control. A total of 354 AHT hospitalisations were identified and the incidence for the state was 22.8 per 100 000 children under the age of one. Over 11 per cent of these children died. Risk factors included a teenaged mother at the time of birth, births paid for using public insurance, child's low birth weight, and maternal Native American race. The strongest risk factor was a prior CPS allegation, a similar finding to a California study on injury mortality. The practice and policy implications of these findings are discussed.

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.

Paediatric abusive head trauma in the emergency department: A multicentre prospective cohort study

AIM

Abusive head trauma (AHT) is associated with high morbidity and mortality. We aimed to describe characteristics of cases where clinicians suspected AHT and confirmed AHT cases and describe how they differed.

METHODS

This was a planned secondary analysis of a prospective multicentre cohort study of head injured children aged <18 years across five centres in Australia and New Zealand. We identified cases of suspected AHT when emergency department clinicians raised suspicion on a clinical report form or based on research assistant-assigned epidemiology codes. Cases were categorised as AHT positive, negative and indeterminate after multidisciplinary review. Suspected and confirmed AHT and non-AHT cases were compared using odds ratios with 95% confidence intervals.

RESULTS

AHT was suspected in 70 of 13 371 (0.5%) head-injured children. Of these, 23 (32.9%) were categorised AHT positive, 18 (25.7%) AHT indeterminate and 29 (27.1%) AHT negative. Median age was 0.8 years in suspected, 1.4 years in confirmed AHT and 4.1 years in non-AHT cases. Odds ratios (95% confidence interval) for presenting features and outcomes in confirmed AHT versus non-AHT were: loss of consciousness 2.8 (1.2-6.9), scalp haematoma 3.9 (1.7-9.0), seizures 12.0 (4.0-35.5), Glasgow coma scale ≤12 30.3 (11.8-78.0), abnormal neuroimaging 38.3 (16.8-87.5), intensive care admission 53.4 (21.6-132.5) and mortality 105.5 (22.2-500.4).

CONCLUSIONS

Emergency department presentations of children with suspected and confirmed AHT had higher rates of loss of consciousness, scalp haematomas, seizures and low Glasgow coma scale. These cases were at increased risk of abnormal computed tomography scans, need for intensive care and death.

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.

Incidence of nonaccidental head trauma in infants: a call to revisit prevention strategies

OBJECTIVE

Traumatic brain injury is a major sequela of nonaccidental trauma (NAT) that disproportionately affects young children and can have lasting sequelae. Considering the potentially devastating effects, many hospitals develop parent education programs to prevent NAT. Despite these efforts, NAT is still common in Western New York. The authors studied the incidence of NAT following the implementation of the Western New York Shaken Baby Syndrome Education Program in 1998.

METHODS

The authors performed a retrospective chart review of children admitted to our pediatric hospital between 1999 and 2016 with ICD-9-CM and ICD-10-CM codes for types of child abuse and intracranial hemorrhage. Data were also provided by the Safe Babies New York program, which tracks NAT in Western New York. Children with a diagnosis of abuse at 0-24 months old were included in the study. Children who suffered a genuine accidental trauma or those with insufficient corroborating evidence to support the NAT diagnosis were excluded.

RESULTS

A total of 107 children were included in the study. There was a statistically significant rise in both the incidence of NAT (p = 0.0086) and the incidence rate of NAT (p = 0.0235) during the study period. There was no significant difference in trendlines for annual NAT incidence between sexes (y-intercept p = 0.5270, slope p = 0.5263). When stratified by age and sex, each age group had a distinct and statistically significant incidence of NAT (y-intercept p = 0.0069, slope p = 0.0374).

CONCLUSIONS

Despite educational interventions targeted at preventing NAT, there is a significant rise in the trend of newly reported cases of NAT, indicating a great need for better injury prevention programming.

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.

Incidence and Age Distribution of Hospitalized Presumptive and Possible Abusive Head Trauma of Children Under 12 Months Old in Japan

Background

Abusive head trauma (AHT) is the leading cause of fatal maltreatment among young children. The incidence of AHT in Japan, however, remains unknown. This study examined the incidence and distribution of age in months among young children under 12 months of age hospitalized with intracranial injury in Japan.

Methods

We conducted a multicenter cross-sectional study of children under 36 months old admitted with intracranial injury to hospitals that employed the Diagnostic Procedure Combination (DPC) payment system between 2010 and 2013. Presumptive and possible AHT were defined using the combination of ICD-10 codes modified from the coding system recommended by the United States Centers for Disease Control and Prevention.

Results

The average incidence was 7.2 (95% confidence interval [CI], 7.18–7.26) for presumptive and 41.7 (95% CI, 41.7–41.8) for possible AHT per 100,000 children less than 12 months old from 2010 to 2013. The distributions of age in months for both presumptive AHT and possible AHT had peaks at around 2 and 8 months.

Conclusions

This is the first study to report the incidence of hospitalized children with presumptive and possible AHT using population-based data. Further datasets are needed to evaluate the incidence and specific preventive strategies to prevent AHT in infants during the months of highest risk.

Parasagittal vertex clots on head CT in infants with subdural hemorrhage as a predictor for abusive head trauma

BACKGROUND

Abusive head trauma (AHT) is the most common cause of subdural hemorrhage (SDH) in infants younger than 12 months old. Clot formation in the parasagittal vertex seen on imaging has been associated with SDH due to AHT. There have been very few studies regarding these findings; to our knowledge, no studies including controls have been performed.

OBJECTIVE

To describe parasagittal vertex clots on head computed tomography (CT) in infants with SDH and AHT compared to patients with SDH and accidental trauma, and to evaluate for parasagittal vertex clots in the absence of SDH in the setting of known accidental head trauma.

MATERIALS AND METHODS

All infants younger than 12 months old with SDH present on CT scan were retrospectively identified from 2004 to 2014. Blinded, independent review of all CT scans for clot formation at the parasagittal vertex was performed by a pediatric neuroradiologist.

RESULTS

Ninety-nine patients were eligible for analysis. Mean age was 4 months. Fifty-seven (57.6%) were male. Fifty-five (55.6%) patients were identified as having AHT and 22 (22.2%) had accidental trauma. Forty-five (81.2%) patients with AHT had parasagittal vertex clots present on CT scan compared to 8 (36.4%) patients with accidental trauma. Compared to patients without parasagittal vertex clots, those with parasagittal vertex clots were more likely to have AHT (66.2% vs. 32.3%, P=0.001), no known mechanism of injury (69.1% vs. 32.3%, P=0.015), retinal hemorrhage (75% vs. 35.5%, P=0.002) and hypoxic-ischemic changes (25% vs. 0%, P=0.002). Patients with parasagittal vertex clots have eight times the odds of AHT compared to patients without parasagittal vertex clots. Age-matched control patients who underwent head CT scan due to a history of accidental head injury without SDH were identified (n=87); no patient in the control group had parasagittal vertex clots.

CONCLUSION

The finding of parasagittal vertex clots on CT scans should raise suspicion for abuse and prompt further investigation, especially in the setting of no known, uncertain or inconsistent mechanism of injury.

The Utility of Head Computed Tomography in the Evaluation of Apparent Life-Threatening Event

OBJECTIVE

This study aimed to evaluate the diagnostic utility of empiric head computed tomography (CT) in apparent life threatening event (ALTE).

METHODS

This was a retrospective chart review of children younger than 12 months presenting to an urban pediatric hospital and its suburban satellite for an ALTE from October 2009 to December 2012. The ALTE cases were identified as having had a diagnosis of ALTE (International Classification of Diseases, 9th Revision 799.82) or as having had a constellation of studies performed consistent with our institutional protocol for ALTE evaluation. Exclusion criteria were known trauma and cases lacking an identifiable ALTE feature on review.

RESULTS

There were 631 cases identified, of which 617 met inclusion and exclusion criteria. Of those, 537 had a head CT performed. Five patients were identified with clinically important head CT findings: a case of congenital toxoplasmosis, a case of intraventricular hemorrhage, and 3 cases of nonaccidental trauma (NAT). One of the NAT patients had a bruise on his forehead; the other patients had no historical, physical examination, and other laboratory or radiologic findings to raise concern for significant finding on head CT. The rate of clinically significant findings and occult clinically significant findings was 5/537 (0.93%) (95% confidence interval, 0.30%-2.16%; number needed to treat = 108) and 4/537 (0.75%) (95% confidence interval, 0.20%-1.90%; number needed to treat = 135), respectively.

CONCLUSIONS

The rate of clinically important head CT findings in ALTE evaluation was relatively rare, at 0.93%. Given the severe consequences of missing these cases, these data establish a role for empiric head CT in the evaluation of ALTE.

Risk factors for maltreatment-related infant hospitalizations in New York City, 1995-2004

BACKGROUND

Child maltreatment is a major public health problem, but population-based surveillance and research is hindered by limitations of official child welfare data. The present study used a promising complementary data source, hospital discharge data, to investigate risk factors for infant injuries suggestive of maltreatment.

METHODS

Discharge data from all hospital births to New York City residents from 1995 to 2004 were linked to birth certificates and to subsequent infant hospitalizations within 12 months after delivery. Probable maltreatment of infants was identified with 33 injury diagnosis codes highly correlated with maltreatment. Modified Poisson regression estimated the association of sociodemographic factors and pregnancy/birth characteristics with subsequent infant admission for probable maltreatment.

RESULTS

Risk factors for maltreatment included neonatal intensive care unit stays of more than 11 days (adjusted risk ratio [aRR] = 1.8; 95% confidence interval [CI]: 1.1-2.8), preterm birth (aRR = 1.6; 95% CI: 1.2-2.1), maternal age less than 20 years (aRR = 1.5; 95% CI: 1.2-1.9), and public insurance (aRR = 1.5; 95% CI: 1.2-1.9). Factors associated with reduced maltreatment risk included mother born outside the United States (aRR = 0.7; 95% CI: 0.6-0.8) and female infant (aRR = 0.7; 95% CI: 0.6-0.9).

CONCLUSIONS

Sociodemographic factors and challenges at birth (preterm, neonatal intensive care unit stays) are important risk factors for subsequent maltreatment-related hospitalization, with potential implications for prevention targeting.

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.

Seizure Severity Is Correlated With Severity of Hypoxic-Ischemic Injury in Abusive Head Trauma

BACKGROUND

The objective of this study was to characterize hypoxic-ischemic injury and seizures in abusive head trauma.

METHODS

We studied 58 children with moderate or severe traumatic brain injury due to abusive head trauma. Continuous electroencephalograms and magnetic resonance images were scored.

RESULTS

Electrographic seizures (51.2%) and hypoxic-ischemic injury (77.4%) were common in our cohort. Younger age was associated with electrographic seizures (no seizures: median age 13.5 months, interquartile range five to 25 months, versus seizures: 4.5 months, interquartile range 3 to 9.5 months; P = 0.001). Severity of hypoxic-ischemic injury was also associated with seizures (no seizures: median injury score 1.0, interquartile range 0 to 3, versus seizures: 4.5, interquartile range 3 to 8; P = 0.01), but traumatic injury severity was not associated with seizures (no seizures: mean injury score 3.78 ± 1.68 versus seizures: mean injury score 3.83 ± 0.95, P = 0.89). There was a correlation between hypoxic-ischemic injury severity and seizure burden when controlling for patient age (r_s=0.61, P < 0.001). The ratio of restricted diffusion volume to total brain volume (restricted diffusion ratio) was smaller on magnetic resonance imaging done early (median restricted diffusion ratio 0.03, interquartile range 0 to 0.23 on magnetic resonance imaging done within two days versus median restricted diffusion ratio 0.13, interquartile range 0.01 to 0.43 on magnetic resonance imaging done after two days, P = 0.03).

CONCLUSIONS

Electrographic seizures are common in children with moderate to severe traumatic brain injury from abusive head trauma, and therefore children with suspected abusive head trauma should be monitored with continuous electroencephalogram. Severity of hypoxic-ischemic brain injury is correlated with severity of seizures, and evidence of hypoxic-ischemic injury on magnetic resonance imaging may evolve over time. Therefore children with a high seizure burden should be reimaged to evaluate for evolving hypoxic-ischemic injury.
