Pediatric Abusive Head Trauma Prevention Initiatives: A Literature Review

Pediatric Trauma Recidivism: A Statewide Risk Factor Analysis of the Maryland Health Services Cost Review Commission (HSCRC)

BACKGROUND

National estimates suggest pediatric trauma recidivism is uncommon but are limited by short follow up and narrow ascertainment. We aimed to quantify the long-term frequency of trauma recidivism in a statewide pediatric population and identify risk factors for re-injury.

METHODS

The Maryland Health Services Cost Review Commission Dataset was queried for 0-19-year-old patients with emergency department or inpatient encounters for traumatic injuries between 2013 and 2019. We measured trauma recidivism by identifying patients with any subsequent presentation for a new traumatic injury. Univariate and multivariable regressions were used to estimate associations of patient and injury characteristics with any recidivism and inpatient recidivism.

RESULTS

Of 574,472 patients with at least one injury encounter, 29.6% experienced trauma recidivism. Age ≤2 years, public insurance, and self-inflicted injuries were associated with recidivism regardless of index treatment setting. Of those with index emergency department presentations 0.06% represented with an injury requiring inpatient admission; unique risk factors for ED-to-inpatient recidivism were age >10 years (aOR 1.61), cyclist (aOR 1.31) or burn (aOR 1.39) mechanisms, child abuse (aOR 1.27), and assault (aOR 1.43). Among patients with at least one inpatient encounter, 6.3% experienced another inpatient trauma admission, 3.4% of which were fatal. Unique risk factors for inpatient-to-inpatient recidivism were firearm (aOR 2.48) and motor vehicle/transportation (aOR 1.62) mechanisms of injury (all p < 0.05).

CONCLUSIONS

Pediatric trauma recidivism is more common and morbid than previously estimated, and risk factors for repeat injury differ by treatment setting. Demographic and injury characteristics may help develop and target setting-specific interventions.

Identification and Evaluation of Non-Accidental Trauma in the Pediatric Population: A Clinical Review

Non-accidental trauma (NAT) is a major cause of morbidity and mortality for children around the world and most significantly impacts children under one year of age. Prompt and comprehensive treatment of these children relies on a high index of suspicion from any medical provider that treats pediatric patients. This review discusses those most at risk for experiencing NAT, and common initial presentations, to assist providers in the identification of potential victims. In addition, this review provides guidance on the recommended workup for these patients so that the full extent of associated injuries may be identified and the appropriate healthcare team may be assembled.

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.

Identifying abusive head trauma and its mimics: diagnostic nuances

BACKGROUND

Abusive head trauma (AHT) is the most serious injury inflicted to the nervous system of neonate an infant with a high incidence of disabilities. The authors present two cases in which the initial manifestations and neurologic status were misinterpreted and stress that clinical presentation and imaging can be variable and confuse the examiner.

DISCUSSION

Subdural hemorrhage (SDH) in this age group raises high suspicion of non-accidental trauma but have been reported in other situations such as several bleeding disorders. Although rare, hematological diseases should be considered when other data of maltreatment are lacking.

CONCLUSION

Differential diagnosis is important to avoid underdiagnosing AHT and to prevent morbidity if a pre-existing hematological disease is misdiagnosed.

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.

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.

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.

Pediatric abusive head trauma: ThinkFirst national injury prevention foundation

Background:

Pediatric abusive head trauma (AHT) represents 80% of nonaccidental trauma deaths, remaining a lead cause of death among infants and young children. Furthermore, neurosurgical intervention can ameliorate damage from secondary injury, but we are currently unable to alter the impact of the primary injury. Thus, prevention through increased public awareness is imperative. This study identifies injuries and predictors of outcomes in pediatric AHT and highlights the importance of partnering with our community through ThinkFirst, a national injury prevention foundation, to educate parents and caregivers about prevention.

Methods:

This single-institution retrospective review identifies injuries and predictors of outcomes in pediatric AHT and highlights the importance of partnering with our community to raise awareness and educate parents and caregivers about prevention.

Results:

The number of pediatric AHT cases continues to steadily increase over time (P < 0.001), and over 70% of these patients are <1 year of age (P < 0.001). Patients suffering AHT have a mortality rate of nearly 10%. In addition to morbidity and mortality, the economic burden of caring for abused children is high as they often require high levels of care, long hospital stays, and extensive rehabilitation. Furthermore, Medicaid pays for nearly 80% of these patients.

Conclusion:

The population of patients with AHT is unique, and one that will benefit from continued efforts at increased multidisciplinary and public awareness. Prevention of AHT through awareness is critical. Through partnering with ThinkFirst, a national injury prevention foundation, we aim to educate parents and caregivers about prevention.

Preventing abusive head trauma: can educating parents reduce the incidence?

Abusive head trauma (AHT) is the most lethal form of child abuse; preventing AHT should be a national priority, but research into this area is woefully underfunded. Prevention programs have primarily focused on universal parent education during the neonatal period, a time when parents are a captive audience of the health care establishment whose focus is on the needs of their newborn infant, and who will soon be exposed to the frustration and anger of infant crying. Research has suggested a strong causal link between infant crying and AHT, and parents - particularly fathers and father figures - have been identified as the most common perpetrators of AHT. A number of studies have suggested that educating parents during the postnatal period about the normalcy of inconsolable infant crying and its evolution over the first several months of postnatal life improves parental knowledge about infant crying and a number of positive parenting behaviors, and decreases emergency room visits for crying. In 1998, we began a pilot program in Upstate New York near Buffalo that led to a 47% reduction in AHT incidence. Similar studies have demonstrated 35-75% reductions in incidence, which has led to enthusiasm for this approach to preventing AHT. We, as well as another group, have enacted statewide programs in Pennsylvania and North Carolina; unfortunately, these two large statewide replication trials failed to demonstrate any impact of such an intervention on AHT rates. Serial messages for parents, provided repeatedly over the period of greatest risk for AHT, might be another avenue of research.

Parental knowledge on infant crying and abusive head trauma and relevant shaking behaviors in China

BACKGROUND

This study aims to characterize the knowledge about infant crying and abusive head trauma (AHT), and shaking behaviors in parents of children in China, which are lacking currently.

METHODS

A cross-sectional survey was conducted in 2020. We collected information about the knowledge of the typical patterns of infant crying and AHT, and asked about beliefs of the effects of violent shaking on children's health, and shaking behavior among parents.

RESULTS

A total of 568 parents completed the questionnaire, and only 1.6 % of them answered all nine knowledge questions related to infant crying correctly. Overall, 42.6 % of participants reported they had heard about AHT, but only 17.1 % of the parents reported they knew enough about the dangers of infant shaking. About 45 % of the parents acknowledged that they had shaken their infants at least once. Parents who were from western region of China (OR = 3.860; 95 % CI = 1.871, 7.966; p < 0.001) and have felt very frustrated because of the baby's crying over half of the time (OR = 3.401; 95 % CI = 1.862, 6.211; p < 0.001) had the highest risk of shaking. Majority of the parents reported that they needed further information about infant soothing techniques, knowledge of prevention and treatment about AHT.

CONCLUSIONS

Majority of Chinese parents do not have enough knowledge about normal infant crying, nevertheless, most of them expressing needs in learning more. Community-wide advocating efforts aiming to educate parents on awareness and knowledge about AHT should be a health priority in China.

Which Mothers Know That All Babies Cry? A Randomized Controlled Trial of a Child Abuse Prevention Program for Low-Income New Mothers

This study evaluated an intervention for low-income new mothers, half from Spanish-speaking homes, that provides education around infant crying and abusive head trauma (AHT). At enrollment, non-US-born mothers were less likely than US-born mothers to have heard of shaken baby syndrome (60% vs 89%, P ≤ .0001) or to know shaking babies could lead to brain damage or death (48% vs 80%, P < .0001). At follow-up, non-US-born intervention mothers had improved knowledge of the peak of crying (31% vs 4%, P = .009), improved knowledge that shaking a baby could lead to brain damage or death (36% vs 12%, P = .035), and identified more calming strategies for parenting stress compared with non-US-born control mothers (+0.8 [SD = 1.1] vs -0.4 [SD = 1.4]). This study identifies a gap in AHT knowledge at baseline of non-US-born mothers. These mothers had improved knowledge with intervention and are an important population for similar prevention efforts.

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.

Understanding Abusive Head Trauma: A Primer for the General Pediatrician

Abusive head trauma (AHT) refers to a well-recognized constellation of injuries caused by the direct application of force to an infant or young child, resulting in trauma to the head, intracranial contents, and/or neck, with potentially devastating health outcomes. Mechanisms of AHT include impulsive injurious acts, such as violent shaking and impact, often due to caregiver frustration or exhaustion. Subdural and retinal hemorrhage, and associated extracranial injury (fractures, abdominal trauma), are common. Suspected victims require laboratory/diagnostic testing and occult injury screening, as well as protective measures by investigative authorities to ensure safety. Medicolegal controversies persist around AHT diagnosis, including alternative hypotheses proffered in court by skeptics despite advances in scientific understanding, biomechanical research, neuroimaging techniques, and perpetrator confessions. Pediatricians play a key role in prevention and reduction of AHT morbidity and mortality through anticipatory guidance and caregiver education about the risks of shaking, normal infant development and behavior, and encouragement of stress reduction strategies.

Protecting the blossoming brain - Neurocritical care in children

This special issue of the Biomedical Journal is entirely dedicated to the latest updates regarding the medical efforts to preserve the fragile young brain after injury. Thereby, we learn about symptoms and diseases such as different forms of epilepsy, acute encephalopathy, increased intracranial pressure, and posthaemorrhagic hydrocephalus, as well as about their origins, such as infection, autoimmune diseases, preterm birth, or abusive head trauma. Moreover, diagnosis and surveillance techniques are discussed, including ultrasound of the optic nerve sheath diameter and multimodal monitoring. Finally, we discover various established and emerging therapeutic approaches, comprising target temperature management, ketogenic diet, and immunomodulation.

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.

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.
