Abusive head trauma

Developmental Outcomes Following Abusive Head Trauma in Infancy: A Systematic Review

OBJECTIVE

A systematic review of the literature was conducted to identify measures used to evaluate developmental outcomes after abusive head trauma (AHT), as well as describe outcomes among those with AHT, and explore factors and interventions influencing such outcomes.

DESIGN

This systematic review adheres to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines. The protocol is in PROSPERO, registration number CRD42020179592. On April 17, 2020, OVID Medline, Embase, OVID PsycINFO, Web of Science, CINAHL, Cochrane Library, and Google Scholar were searched (since inception). Inclusion criteria included original, peer-reviewed study data; AHT exposure; infants younger than 24 months at time of AHT; and evaluation of developmental outcomes. Reviewers independently evaluated studies for inclusion and assessed risk of bias using the Effective Public Health Practice Project quality assessment tool for quantitative studies. A descriptive synthesis approach was utilized as variability of study designs, follow-up periods, and outcome assessment tools precluded a meta-analytic approach.

RESULTS

Fifty-nine studies were included; 115 assessment tools were used to evaluate developmental outcomes; and 42 studies examined factors influencing outcomes. Two studies evaluated interventions. Five percent of studies ( n = 3) were rated low risk of bias.

CONCLUSIONS

Notable variation was observed in terms of case ascertainment criteria. Developmental outcomes after AHT have been assessed in a manner that limits understanding of how AHT impacts development, as well as the efficacy of interventions intended to improve outcomes. Researchers and clinicians are encouraged to adopt consistent diagnostic and assessment approaches.

Which Clinical Features of Children on Initial Presentation to the Emergency Department With Head Injury Are Associated With Clinically Important Traumatic Brain Injury, Classification as Abuse, and Poor Prognosis?

BACKGROUND

Pediatric traumatic brain injury (TBI) and abusive head trauma (AHT) are leading causes of morbidity and mortality. Clinicians may not be aware of AHT at presentation to the emergency department (ED).

OBJECTIVE

The objective of this study was to determine which clinical features associated with head injury in children on initial presentation to the ED trauma bay predict 3 outcomes including clinically important TBI (CiTBI), classification as confirmed abuse by Child Protection Team (CPT), and poor neurologic status on hospital discharge.

PARTICIPANTS AND SETTING

Inclusion for this study were children 3 years or younger, presenting to the ED with significant TBI. In addition, presentations where the mechanism of injury was not verifiable such as with falls, being struck by object, or no mechanism of injury reported by caregiver were included.

METHODS

Researchers used 3 sources of information for this analysis: a regional trauma registry, hospital records, and the CPT database. Clinical features included demographics, mechanisms of injury, physical, radiological findings, and CPT classification.

RESULTS

On pairwise analysis, seizures, apnea, and no mechanism of injury reported by caregiver were the only clinical features related to all 3 outcomes (P < 0.001). Rib fractures (relative risk [RR], 3.3; P < 0.001), long bone fractures (RR, 3.1; P < 0.001), retinal hemorrhages (RR, 3.0; P < 0.001), seizures (RR, 3.6; P < 0.001), apnea (RR, 4.4; P < 0.001), and younger than 6 months (RR, 1.8; P < 0.001) were related to AHT. On multivariable logistic regression, no mechanism of injury reported by caregiver and seizures remained significantly related to CiTBI; seizures and retinal hemorrhage remained significantly related to classification as abuse by CPT, and no mechanism of injury by the caregiver, apnea, and seizures were significantly related to poor outcome on hospital discharge.

CONCLUSIONS

No mechanism of injury reported by the caregiver, seizures, and apnea at the time of presentation to the ED are important features associated with CiTBI, classification as AHT, and poor prognosis. In addition, younger age, retinal hemorrhage, rib, and long bone fractures were found to be important clinical features associated with AHT.

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.

Abusive head trauma: experience improves diagnosis

PURPOSE

The diagnosis of abusive head trauma (AHT) is complex and neuroimaging plays a crucial role. Our goal was to determine whether non-neuroradiologists with standard neuroradiology knowledge perform as well as neuroradiologists with experience in pediatric neuroimaging in interpreting MRI in cases of presumptive AHT (pAHT).

METHODS

Twenty children were retrospectively evaluated. Patients had been diagnosed with pAHT (6 patients), non-abusive head trauma-NAHT (5 patients), metabolic diseases (3 patients), and benign enlargement of the subarachnoid spaces (BESS) (6 patients). The MRI was assessed blindly, i.e., no clinical history was given to the 3 non-neuroradiologists and 3 neuroradiologists from 2 different institutions.

RESULTS

Blindly, neuroradiologists demonstrated higher levels of sensitivity and positive predictive value in the diagnosis of pAHT (89%) than non-neuroradiologists (50%). Neuroradiologists chose correctly pAHT as the most probable diagnosis 16 out of 18 times; in contrast, non-neuroradiologists only chose 9 out of 18 times. In our series, the foremost important misdiagnosis for pAHT was NAHT (neuroradiologists twice and non-neuroradiologists 5 times). Only victims of motor vehicle accidents were blindly misdiagnosed as pAHT. No usual household NAHT was not misdiagnosed as pAHT. Neuroradiologists correctly ruled out pAHT in all cases of metabolic diseases and BESS.

CONCLUSION

MRI in cases of suspected AHT should be evaluated by neuroradiologists with experience in pediatric neuroimaging. Neuroradiologists looked beyond the subdural hemorrhage (SDH) and were more precise in the assessment of pAHT and its differential diagnosis than non-neuroradiologists were. It seems that non-neuroradiologists mainly assess whether or not a pAHT is present depending on the presence or absence of SDH.

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. [Pediatr Ann. 2020;49(8):e347-e353.].

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.

The importance of optic nerve sheath hemorrhage as a postmortem finding in cases of fatal abusive head trauma: A 13-year study in a tertiary hospital

Fatal abusive head trauma is a major cause of death in children and toddlers who suffer from cruel physical abuse. Postmortem differentiation of fatal abusive head trauma from accidental head trauma can be a complicated process. This consecutive case series study aimed to determine the role of subdural optic nerve sheath hemorrhage (ONSH) in 70 autopsy cases of children ≤3 years old in making this differentiation. The study took place over a 13 year period (between August 1st 2003 and July 31st 2016) at a tertiary hospital in Thailand. Eleven cases were diagnosed with fatal abusive head trauma and 10 were identified as being accidental closed head trauma cases. Bilateral retinal hemorrhage was noted in antemortem medical records in every hospitalized abusive head trauma case (n=10). Upon autopsy, ONSH was observed in all 11 fatal cases of abusive head trauma (bilateral=10 and unilateral=1) but not in any cases of accidental head trauma (0/5). Subdural hemorrhage was found in 10 out of 11 abusive head trauma victims but not in any of the 10 with accidental head trauma. Other postmortem findings in abusive head trauma included subarachnoid hemorrhage (5/11), marked brain swelling (3/11), skull fracture (4/11) and brain contusion (1/11). This study suggests that ONSH, together with subdural hemorrhage, plays an essential role in an accurate postmortem diagnosis of fatal abusive head trauma. Therefore, an ocular investigation should be performed in all autopsy cases where child abuse is suspected and where there is no reliable history/witnesses, confession or antemortem ophthalmologic examination.

The impact of an educational intervention on knowledge about infant crying and abusive head trauma

BACKGROUND

Infants follow a predictable trajectory of increased early crying. Frustration with crying is reported to be a trigger for abusive head trauma (AHT).

OBJECTIVE

To evaluate the impact of postpartum delivery of the educational program, the Period of PURPLE Crying (PURPLE), in a group of first-time mothers. The primary objective was to determine whether there was a change in knowledge about infant crying and shaking after exposure to PURPLE. Factors associated with change in knowledge were also examined.

METHOD

A total of 93 participants were recruited over a four-month period at a tertiary care hospital in Nova Scotia. Pre- and postintervention data were collected.

RESULTS

Knowledge about infant crying increased significantly after program delivery (P=0.001). Low baseline crying knowledge was a significant predictor of increased knowledge about infant crying (P≤0.01). There was an insignificant decrease in shaking knowledge (P=0.5), which may have been the consequence of high baseline knowledge.

CONCLUSION

An educational program for new parents appears to be warranted, especially with respect to improving knowledge about infant crying. This may have a positive benefit in AHT prevention. Additional studies are required to evaluate the impact of the program on other caregivers and on rates of AHT.

Abusive head trauma: two case reports

Abusive head trauma is a serious form of child abuse and mostly seen in infants below the age of two years as a result of a strong shaking by the caregiver who aims to stop the infant's crying. Characteristic symptoms include subdural hematomas, encephalopathy, retinal hemorrhages and fractures of the long bones. When physically examined, there are generally no externally visible signs. For this reason, it can be underdiagnosed, if it is not considered in the differential diagnosis. When the information provided from the parents is inconsistent and contradictory with the clinical picture of the patient, this form of abuse must be suspected and retinal hemorrhages should be searched. In this article, two patients who were admitted to our emergency department and diagnosed with physical child abuse are reported. One of these patients had a history of minor head trauma after falling down from the sofa and the other one had a history of breathlessness and loss of consciousness as a result of excessive crying.

The optic nerve sheath hemorrhage is a non-specific finding in cases of suspected child abuse

In young infants, the triad consisting of acute encephalopathy, retinal hemorrhages, and a subdural hematoma is a nonspecific finding. It has traumatic and non-traumatic etiologies. The triad may be found among a vast spectrum of natural diseases. Optic nerve sheath hemorrhage in infants is typically detected at autopsy. It is a nonspecific finding that can be found in traumatic and non-traumatic etiologies. Neither the triad nor the ONSH are pathognomonic for an abusive head injury. Opposite to the triad, the spectrum of non-traumatic etiologies of ONSH is limited. In infants ONSH rarely occurs in spontaneous subarachnoidal hemorrhage or in infectious conditions. Our results show that the clinical significance of the optic nerve sheath hemorrhage in the forensic work-up of fatal cases of alleged abusive head injury is its limited differential diagnosis. Only after careful differential diagnosis ONSH may contribute to the diagnosis of AHT. However, the main limitation of our study is the sampling bias, as the eyes are usually removed when abusive head trauma is suspected.

Long-term outcomes of the shaken baby syndrome prevention program: Turkey's experience

AIM

Shaken baby syndrome (SBS) is a condition which may cause to serious health problems in the baby. SBS may be prevented by increasing awareness with giving education to parents especially in the early postnatal period. In shaken baby prevention programs, education is recommended to be given before the 2-4(th) month during which the frequency of crying is increased. It is important that education given in the early period is permanent until the period during which the frequency of crying is increased. The aim of this study was to evaluate the persistency of the benefit of the SBS prevention program until the 2-4(th) month during which crying is intensified.

MATERIAL AND METHODS

This study is an interventional study. When the babies became 2-4 months old, a questionnaire which questioned the usefulness of education and the experiences with babies was applied to a group selected randomly among the mothers who received SBS prevention education during pregnancy or in the first 7 postnatal days (group A). The same questionnaire was applied to 143 mothers whose babies completed their first 2 months, who presented to the hospital for vaccination and who did not receive education about SBS as the control group (group B). The data were evaluated using the Statistical Program for Social Sciences (SPSS) 15.0 statistical analysis package program. Ethical approval was obtained from the local ethics committee (30.12.2009, 2785).

RESULTS

The rate of the mothers who stated "yes" to the sentence "babies occasionally cry" which was one of the main messages of the education was statistically significantly higher in group A compared to group B (p=0.001). The rate of the mothers who stated "I agree" to the sentence "battering is harmful for babies" was statistically significantly higher in group A compared to group B (p=0.001).

CONCLUSIONS

Conclusively, it was found that SBS prevention program education was permanent until the 2-4(th) month.

Child maltreatment: interventions to improve recognition and reporting

Child maltreatment is a significant public health problem and described as one of the greatest threats facing the health, welfare, and social well-being of children (Centers for Disease Control and Prevention, U.S. Department of Health and Human Services, 2012). The effect of child maltreatment on the children involved, their families, and society as a whole is substantial. Despite mandatory reporting laws, the poignant reality is that child maltreatment is significantly underrecognized and underreported. Interventions must be designed, tested, and implemented to fulfill the goal of child maltreatment prevention. Forensic nurses are uniquely qualified to assume a leadership role and work collaboratively with children, their caregivers, and all members of the interdisciplinary team to ensure the safety and protection of children. The purpose of this article is to present an evidence-based discussion of the scope of the problem of child maltreatment, contributing barriers to recognition and reporting, and suggestions for interventions designed to achieve the goals of primary and secondary prevention.

Special considerations in infants and children

Head injury in children is one of the most common causes of death and disability in the US and, increasingly, worldwide. This chapter reviews the causes, patterns, pathophysiology, and treatment of head injury in children across the age spectrum, and compares pediatric head injury to that in adults. Classification of head injury in children can be organized according to severity, pathoanatomic type, or mechanism. Response to injury and repair mechanisms appear to vary at different ages, and these may influence optimal treatment; however, much work is still needed before investigation leads to clearly effective clinical interventions. This is true both for the more severe injuries as well as those at the milder end of the injury spectrum, the latter of which have received increasing attention. In this chapter, neuroassessment tools for each age, newer imaging modalities including magnetic resonance imaging (MRI), and specific pediatric management issues, including intracranial pressure (ICP) monitoring and seizure prophylaxis, are reviewed. Finally, specific head injury patterns and functional outcomes relevant to pediatric patients are discussed. While head injury is common, the number of head-injured children is significantly smaller than the corresponding adult head-injured population. When divided further by specific ages, injury types, and other sources of heterogeneity, properly powered clinical research is likely to require large data sets that will allow for stratification across variables, including age. While much has been learned in the past several decades, further study will be required to determine the best management practices for optimizing recovery in individual pediatric patients. This approach is likely to depend on collaborative international head injury databases that will allow researchers to better understand the nuanced evolution of different types of head injury in patients at each age, and the pathophysiologic, treatment-related, and genetic factors that influence recovery.

Identifying Characteristics in Abusive Head Trauma: A Single-Institution Experience

Abusive head trauma (AHT) is a significant cause of childhood morbidity and mortality. The purpose of this study was to better understand the trends centered on AHT patients treated at Vanderbilt Children's Hospital. A retrospective study of 139 children undergoing treatment and management for traumatic brain injury due to abuse between January 2006 and April 2013 at Vanderbilt Children's Hospital was conducted. Caucasian males made up 61% and the youngest sibling represented 86.3% of our cohort. The median age was 5 months with injuries occurring during summertime and on weekdays, 31 and 63%, respectively. Seventy-nine percent were diagnosed with subdural hematomas, and 42% had a Glasgow Coma Scale (GCS) of 8 or less. A total of 25 patients, median age 8.6 months, died during our study period. The results of this study describe the AHT population at Vanderbilt Children's Hospital. Future studies should prospectively assess this population to better understand social factors involved in AHT.

Abusive head trauma: past, present, and future

Abusive head trauma has a robust and interesting scientific history. Recently, the American Academy of Pediatrics has endorsed a change in terminology to a term that is more general in describing the vast array of abusive mechanisms that can result in pediatric head injury. Simply defined, abusive head trauma is "child physical abuse that results in injury to the head or brain." Abusive head trauma is a relatively common cause of childhood neurotrauma, with an estimated incidence of 16 to 33 cases per 100,000 children per year in the first 2 years of life. Clinical findings are variable; AHT should be considered in all children with neurologic signs and symptoms, especially if no or only mild trauma is described. Subdural and retinal hemorrhages are the most common findings. The current best evidence-based literature has identified some features--apnea and severe retinal hemorrhages--that reliably discriminate abusive from accidental injury. Longitudinal studies of outcomes in abusive head trauma patients demonstrate that approximately one-third of the children are severely disabled, one third of them are moderately disabled, and one third have no or only mild symptoms. Abusive head trauma cases are complex cases that require a rigorous, multidisciplinary team approach. The clinician can establish this diagnosis with confidence if he/she maintains a high index of suspicion for the diagnosis, has knowledge of the signs, symptoms, and risk factors of abusive head trauma, and reasonably excludes other etiologies on the differential diagnosis.

Head injury pattern in children can help differentiate accidental from non-accidental trauma

OBJECTIVES

Our aim was to define the radiographic findings that help differentiate abusive head trauma (AHT) from accidental head injury.

METHODS

Our trauma registry was queried for all children ≤5 years of age presenting with traumatic brain injury (TBI) from 1996-2011.

RESULTS

Of 2,015 children with TBI, 71% had accidental injury and 29% had AHT. Children with AHT were more severely injured (ISS 22.1 vs 14.4; p < 0.0001) and had a higher mortality rate (15 vs 5%; p < 0.0001). Patients with AHT had higher rates of diffuse axonal injury (14 vs 8%; p < 0.0001) and subdural hemorrhage (76 vs 23%; p < 0.0001). Children with accidental injury had higher rates of skull fractures (52 vs 21%; p < 0.0001) and epidural hemorrhages (11 vs 3%).

CONCLUSIONS

AHT occurred in 29% of children and resulted in increased mortality rates. These children had higher rates of subdural hemorrhages and diffuse axonal injury. Physicians initially evaluating injured children must maintain a high index of suspicion for abuse in those who present with subdural hematoma or diffuse axonal injury.

The medical cost of abusive head trauma in the United States

OBJECTIVES

Health consequences of shaken baby syndrome, or pediatric abusive head trauma (AHT), can be severe and long-lasting. We aimed to estimate the multiyear medical cost attributable to AHT.

METHODS

Using Truven Health MarketScan data, 2003-2011, we identified children 0 to 4 years old with commercial or Medicaid insurance and AHT diagnoses. We used exact case-control matching based on demographic and insurance characteristics such as age and health plan type to compare medical care between patients with and without AHT diagnoses. Using regression models, we assessed service use (ie, average annual number of inpatient visits per patient) and inpatient, outpatient (including emergency department), drug, and total medical costs attributable to an AHT diagnosis during the 4-year period after AHT diagnosis.

RESULTS

We assessed 1209 patients with AHT and 5895 matched controls. Approximately 48% of patients with AHT received inpatient care within 2 days of initial diagnosis, and 25% were treated in emergency departments. AHT diagnosis was associated with significantly greater medical service use and higher inpatient, outpatient, drug, and total costs for multiple years after the diagnosis. The estimated total medical cost attributable to AHT in the 4 years after diagnosis was $47,952 (95% confidence interval [CI], $40,219-$55,685) per patient with AHT (2012 US dollars) and differed for commercially insured ($38,231 [95% CI, $29,898-$46,564]) and Medicaid ($56,691 [95% CI, $4290-$69,092]) patients.

CONCLUSIONS

Children continue to have substantial excess medical costs for years after AHT. These estimates exclude related nonmedical costs such as special education and disability that also are attributable to AHT.

Head injury and unclear mechanism of injury: initial hematocrit less than 30 is predictive of abusive head trauma in young children

PURPOSE

Head injury secondary to abusive head trauma (AHT) is a major cause of morbidity and mortality in susceptible young infants and children. Diagnosing AHT remains challenging and is often complicated by a questionable mechanism of injury. Concern of ionizing radiation risk to children undergoing head CT imaging warrants a selective approach. We aimed to evaluate initial findings that could direct further investigation of AHT.

METHODS

A retrospective review of the trauma databases at a two level one pediatric trauma centers was performed. We reviewed all patients age five years and under with a diagnosis of traumatic brain injury (TBI) from 2002-2011.

RESULTS

A total of 1129 patients (mean age 1.7 ± 1.7 years; 64% male) with TBI were identified, 429 (38%) of which were the result of AHT. Complete data was available for 921 patients (82%) and were included in statistical evaluation. Forty-eight percent of patients in the AHT group had a hematocrit ≤ 30% on presentation compared to 19% of patients in the non-AHT group. On univariate analysis, a hematocrit of ≤ 30% was predictive of AHT as the cause of injury (P<.0001), as was a platelet count of greater than 400,000 (P<.0001). After controlling for age, sex, ISS, GCS on presentation, need for CPR, and survival to hospital discharge, hematocrit of ≤ 30% and platelets of greater than 400,000 were predictive of AHT as the cause of TBI (P<.05).

CONCLUSIONS

In the setting of head injury and unclear history of trauma, a hematocrit of ≤ 30% on presentation increases the likelihood of abusive head trauma in children up to the age of 5 years.

Descriptive factors of abusive head trauma in young children--United States, 2000-2009

OBJECTIVE

Abusive head trauma (AHT) is a leading cause of severe injury in maltreated children in the United States. There is little research from nationally representative datasets available to characterize young children who had AHT compared to non-abusive head trauma (NAHT).

METHODS

Using the recent CDC AHT case definition, we performed a retrospective analysis of 2000, 2003, 2006 and 2009 hospitalization data using the Kids' Inpatient Database (KID) from the Healthcare Cost and Utilization Project. Logistic regression was used to compare AHT to NAHT patients <2 years of age. Socio-demographic data and indicators of socioeconomic status (i.e., insurance status and household income), presence of chronic conditions, injury severity (i.e., length of hospital stay and vital status), hospital specialization (i.e., hospital type), hospital region, and season of admission were used as independent variables.

RESULTS

A weighted sample of 7,603 AHT and 25,339 NAHT patients was identified. National rates for AHT were 39.8 per 100,000 population for children <1 year and 6.8 per 100,000 population for children 1 year old. Compared to NAHT, children with AHT were more often <1 year of age (adjusted odds ratio [aOR]=2.66; 95% confidence interval [CI]: 2.35-3.01), male (aOR=1.10; 95% CI: 1.01-1.20), enrolled in Medicaid (aOR=2.78; 95% CI: 2.49-3.11), hospitalized longer (aOR=8.26; 95% CI: 7.24-9.43), died during hospitalization (aOR=5.12; 95% CI: 4.01-6.53), and seen at children's hospitals (aOR=1.97; 95% CI: 1.63-2.38) and hospitals outside the Northeast [aOR=2.65 (95% CI: 2.10-3.33) for the Midwest, 1.90 (95% CI: 1.52-2.38) for the South and 1.93 (95% CI: 1.45-2.57) for the West, respectively].

CONCLUSIONS

The results confirm that injuries from AHT are more severe and more often lethal than other head injuries. Socioeconomically disadvantaged families with children <1 year are an important focus for primary prevention. The associations of AHT, compared to NAHT with hospital type and hospital region warrant further investigation. Referral or reporting patterns, or true differences in the incidence may contribute to the identified associations.

Primary prevention of pediatric abusive head trauma: a cost audit and cost-utility analysis

OBJECTIVES

To obtain comprehensive, reliable data on the direct cost of pediatric abusive head trauma in New Zealand, and to use this data to evaluate the possible cost-benefit of a national primary prevention program.

METHODS

A 5 year cohort of infants with abusive head trauma admitted to hospital in Auckland, New Zealand was reviewed. We determined the direct costs of hospital care (from hospital and Ministry of Health financial records), community rehabilitation (from the Accident Compensation Corporation), special education (from the Ministry of Education), investigation and child protection (from the Police and Child Protective Services), criminal trials (from the Police, prosecution and defence), punishment of offenders (from the Department of Corrections) and life-time care for moderate or severe disability (from the Accident Compensation Corporation). Analysis of the possible cost-utility of a national primary prevention program was undertaken, using the costs established in our cohort, recent New Zealand national data on the incidence of pediatric abusive head trauma, international data on quality of life after head trauma, and published international literature on prevention programs.

RESULTS

There were 52 cases of abusive head trauma in the sample. Hospital costs totaled $NZ2,433,340, child protection $NZ1,560,123, police investigation $NZ1,842,237, criminal trials $NZ3,214,020, punishment of offenders $NZ4,411,852 and community rehabilitation $NZ2,895,848. Projected education costs for disabled survivors were $NZ2,452,148, and the cost of projected lifetime care was $NZ33,624,297. Total costs were $NZ52,433,864, averaging $NZ1,008,344 per child. Cost-utility analysis resulted in a strongly positive economic argument for primary prevention, with expected case scenarios showing lowered net costs with improved health outcomes.

CONCLUSIONS

Pediatric abusive head trauma is very expensive, and on a conservative estimate the costs of acute hospitalization represent no more than 4% of lifetime direct costs. If shaken baby prevention programs are effective, there is likely to be a strong economic argument for their implementation. This study also provides robust data for future cost-benefit analysis in the field of abusive head trauma prevention.

Abnormal neuroimaging is associated with early in-hospital seizures in pediatric abusive head trauma

BACKGROUND

Abusive head trauma (AHT) is a common condition in children. Little is known in this condition regarding the frequency of seizures, the factors associated with increased risk of seizures, or the association of seizures with outcome. We sought to determine frequency and risks for in-hospital seizures after AHT.

METHODS

This was a single-center, retrospective chart review study at a 270 bed tertiary care referral pediatric hospital.

RESULTS

A total of 54 cases of AHT were identified during the study period. During the first week following hospital admission, 33% of patients were observed to have clinical seizures. The occurrence of clinical seizures after admission was associated with findings on initial CT including midline shift, cerebral edema, and loss of gray white differentiation. MRI findings associated with clinical seizures after admission included midline shift, cerebral edema, infarction, and restricted diffusion. The presenting complaint of seizures or acute mental status changes well as a variety of abnormal imaging findings including gray white blurring, infarction, and edema were associated with short-term outcomes.

CONCLUSIONS

Specific neuroradiologic findings identify children at greater risk for seizures, both clinical and subclinical, following AHT. Clinical and subclinical seizures are common in the initial hospitalization for AHT.

Parent education by maternity nurses and prevention of abusive head trauma

OBJECTIVE

A consortium of the 19 community hospitals and 1 tertiary care children's hospital that provide maternity care in the New York State Hudson Valley region implemented a program to teach parents about the dangers of shaking infants and how to cope safely with an infant's crying. This study evaluated the effectiveness of the program in reducing the frequency of shaking injuries.

METHODS

The educational program, which was delivered by maternity nurses, included a leaflet explaining abusive head trauma ("shaken baby syndrome") and how to prevent it, an 8-minute video on the subject, and a statement signed by parents acknowledging receipt of the information and agreeing to share it with others who will care for the infant. Poisson regression analysis was used to compare the frequency of shaking injuries during the 3 years after program implementation with the frequency during a 5-year historical control period.

RESULTS

Sixteen infants who were born in the region during the 8-year study period were treated at the children's hospital for shaking injuries sustained during their first year of life. Of those infants, 14 were born during the 5-year control period and 2 during the 3-year postimplementation period. The decrease from 2.8 injuries per year (14 cases in 5 years) to 0.7 injuries per year (2 cases in 3 years) represents a 75.0% reduction (P = .03).

CONCLUSIONS

Parent education delivered in the hospital by maternity nurses reduces newborns' risks of sustaining an abusive head injury resulting from shaking during the first year of life.

Impact of an educational intervention on caregivers' beliefs about infant crying and knowledge of shaken baby syndrome

OBJECTIVE

Shaken baby syndrome (SBS) is the leading cause of traumatic infant death. We examined whether the message about not shaking an infant should be included in the newborn anticipatory guidance provided by pediatric residents. The aim of this study was to determine the impact of an educational intervention (Take 5 Safety Plan for Crying) delivered by pediatric residents at newborn hospital discharge on beliefs about infant crying and knowledge of SBS among caregivers of young infants being treated in an urban primary care center.

METHODS

Structured interviews were done in one convenience sample of caregivers before (historical control group) and in a second set of different caregivers after (intervention group) an educational intervention was implemented at hospital discharge. Logistic regression was used to calculate adjusted associations between the intervention and caregivers' beliefs/knowledge.

RESULTS

One hundred ten caregivers were in the historical control group and 112 in the intervention group. The intervention group had more mothers and the infants were younger. Controlling for these differences, intervention group caregivers were more likely to state they would take a break if frustrated with infant crying (OR 3.10, 95% CI, 1.62-5.93), were more likely to state frustration caused infant shaking (OR 2.21, 95% CI, 1.20-4.20), and to state their knowledge of SBS was from hospital staff (OR 3.39, 95% CI, 1.61-4.20).

CONCLUSION

This targeted postpartum intervention incorporated into newborn anticipatory guidance can influence caregivers' beliefs about infant crying and knowledge of SBS.

An unusual case of jaundice in a 2-month-old boy

A 2-month-old previously healthy infant presented to the emergency department with a complaint of projectile vomiting for 4 days and jaundice for the last 2 days. An ultrasound of the abdomen showed no sign of pyloric stenosis. All results of laboratory workups related to gastrointestinal cause for vomiting and jaundice were normal. The patient was admitted for further gastrointestinal workup. Finally, a computed tomographic scan of the head showed active and chronic subdural bilateral hematomas with multiple calvarial fractures consistent with nonaccidental trauma.

Initial predictive factors of outcome in severe non-accidental head trauma in children

OBJECT

The aim of this study is to evaluate the outcome of young children hospitalized for non-accidental head trauma in our PICU, to evaluate PRISM II score in this sub-population of pediatric trauma and to identify factors that might influence the short-term outcome.

MATERIALS AND METHODS

Files of all children less than 2 years old with the diagnosis of non-accidental head trauma over a 10-years period were systematically reviewed. We collected data on demographic information, medical history, clinical status, and management in the PICU. Three severity scores were then calculated: PRISM II, Glasgow Coma Scale (GCS), and Pediatric Trauma Score (PTS). Prognosis value of qualitative variables was tested with a univariate procedure analysis (anemia, diabetes insipidus...). Then, quantitative variables were tested with univariate procedure too (age, weight, PRISM II, GCS, Platelet count, fibrin, prothrombin time (PT)...). Potential association between variables and death was tested using univariate procedure. Variables identified by univariate analysis were then analyzed with multivariate analysis through a forward-stepping logistic regression.

RESULTS

Thirty-six children were included. Mean age was 5.5 months (8 days-21.5 months). Mortality rate was 27.8%. At admission, PTS, PRISM II, GCS, PT, PTT, and diabetes insipidus were significantly altered or more frequent in non survivors. Cutoff value for PRISM II at which risk of mortality increased was 17.5 (sensitivity = 0.8; specificity = 0.88).

CONCLUSION

PRISM II is a reliable and easy performing tool for assessing the prognosis of non-accidental cranial traumatism in young children. GCS and PTS, scores even simpler than PRISM II, showed good accuracy regarding survival prediction.

Practitioner review: beyond shaken baby syndrome: what influences the outcomes for infants following traumatic brain injury?

BACKGROUND

Traumatic brain injury (TBI) in infancy is relatively common, and is likely to lead to poorer outcomes than injuries sustained later in childhood. While the headlines have been grabbed by infant TBI caused by abuse, often known as shaken baby syndrome, the evidence base for how to support children following TBI in infancy is thin. These children are likely to benefit from ongoing assessment and intervention, because brain injuries sustained in the first year of life can influence development in different ways over many years.

METHODS

A literature search was conducted and drawn together into a review aimed at informing practitioners working with children who had a brain injury in infancy. As there are so few evidence-based studies specifically looking at children who have sustained a TBI in infancy, ideas are drawn from a range of studies, including different age ranges and difficulties other than traumatic brain injury.

RESULTS

This paper outlines the issues around measuring outcomes for children following TBI in the first year of life. An explanation of outcomes which are more likely for children following TBI in infancy is provided, in the areas of mortality; convulsions; endocrine problems; sensory and motor skills; cognitive processing; language; academic attainments; executive functions; and psychosocial difficulties. The key factors influencing these outcomes are then set out, including severity of injury; pre-morbid situation; genetics; family factors and interventions.

CONCLUSIONS

Practitioners need to take a long-term, developmental view when assessing, understanding and supporting children who have sustained a TBI in their first year of life. The literature suggests some interventions which may be useful in prevention, acute care and longer-term rehabilitation, and further research is needed to assess their effectiveness.

Child abuse and neglect: a worldwide concern

PURPOSE OF REVIEW

As knowledge about child abuse and neglect increases worldwide, so does the literature on abuse and neglect. The authors explore many studies published this year, with attention to the advances in understanding which are guiding prevention efforts as well as diagnosis and treatment of abuse and neglect.

RECENT FINDINGS

The evidence base for many forms of child abuse continues to grow. Controversy around the diagnosis of child abuse still continues, with current debate focused on the diagnosis of abusive head injury and whether children with vitamin D deficiency are misdiagnosed with abusive fractures. As clinicians begin to understand the factors which may increase child vulnerability to abuse, more sophisticated and focused prevention efforts are being implemented, and researchers are evaluating these efforts with an eye to whether or not they really contribute to prevention.

SUMMARY

The short-term and long-term impact of child maltreatment is significant not only for individuals but for families and communities in which abuse is taking place. General pediatricians have an important role to play with families and in the community as advocates for the protection of children. However, it is clear that specialists in child abuse should also play a role in order for diagnosis and management of abuse to adhere to a high standard of care. This has been validated this year by the creation of Child Abuse Pediatrics as a board certified specialty in the United States. As knowledge about abuse and neglect grows, clinicians are focusing on prevention as well as diagnosis and treatment.
