Traumatic intracranial hemorrhage in pediatrics: Implications of factor XIII deficiency and consumptive coagulopathy in abusive head trauma evaluation.

For infants that present with intracranial hemorrhage in the setting of suspected abusive head trauma (AHT), the standard recommendation is to perform an evaluation for a bleeding disorder. Factor XIII (FXIII) deficiency is a rare congenital bleeding disorder associated with intracranial hemorrhages in infancy, though testing for FXIII is not commonly included in the initial hemostatic evaluation. The current pediatric literature recognizes that trauma, especially traumatic brain injury, may induce coagulopathy in children, though FXIII is often overlooked as having a role in pediatric trauma-induced coagulopathy. We report an infant that presented with suspected AHT in whom laboratory workup revealed a decreased FXIII level, which was later determined to be caused by consumption in the setting of trauma induced coagulopathy, rather than a congenital disorder. Within the Child Abuse Pediatrics Research Network (CAPNET) database, 85 out of 569 (15 %) children had FXIII testing, 3 of those tested (3.5 %) had absent FXIII activity on qualitative testing, and 2 (2.4 %) children had activity levels below 30 % on quantitative testing. In this article we review the literature on the pathophysiology and treatment of low FXIII in the setting of trauma. This case and literature review demonstrate that FXIII consumption should be considered in the setting of pediatric AHT.

Child Health Needs and the Child Abuse Pediatrics Workforce: 2020-2040.

Child abuse pediatrics (CAP) subspecialists evaluate, diagnose, and treat children when abuse or neglect is suspected. Despite the high rates of child maltreatment across the United States, CAP remains the smallest pediatric subspecialty. The CAP workforce faces numerous challenges, including few fellows entering the field, decreased financial compensation compared with other fields of medicine, and threats to workforce retention, including secondary trauma and harmful exposure in the media. A microsimulation model that estimates the future of the US CAP workforce over the next 20 years shows that, although the number of child abuse pediatricians in the field is expected to increase, the growth is smaller than that of every other pediatric subspecialty. In addition to the low overall CAP workforce in the United States, other workforce issues include the need to increase CAP subspecialists who are underrepresented in medicine and unequal geographic distribution across the country. To meet the medical needs of suspected victims of maltreatment, especially in CAP-underserved areas, many children are evaluated by providers who are not board-certified in CAP, such as general pediatricians, family medicine physicians, emergency medicine physicians, and advanced practice providers, whose CAP experience and training may vary. Current child abuse pediatricians should continue introducing the field to medical students and residents, especially those who identify as underrepresented in medicine or are from CAP-underserved areas, and offer mentorship, continuing education, and oversight to non-CAP physicians meeting this population's medical needs.

Predictors of Making a Referral to Child Protective Services Prior to Expert Consultation.

OBJECTIVE: Suspicion for child abuse is influenced by implicit biases. Evaluation by a Child Abuse Pediatrician (CAP) may reduce avoidable child protective services (CPS) referrals. Our objective was to investigate the association of patient demographic, social and clinical characteristics with CPS referral before consultation by a CAP (preconsultation referral). METHODS: Children<5years-old undergoing in-person CAP consultation for suspected physical abuse from February 2021 through April 2022 were identified in CAPNET, a multicenter child abuse research network. Marginal standardization implemented with logistic regression analysis examined hospital-level variation and identified demographic, social, and clinical factors associated with preconsultation referral adjusting for CAP's final assessment of abuse likelihood. RESULTS: Among the 61% (1005/1657) of cases with preconsultation referral, the CAP consultant had low concern for abuse in 38% (384/1005). Preconsultation referrals ranged from 25% to 78% of cases across 10 hospitals (P < .001). In multivariable analyses, preconsultation referral was associated with public insurance, caregiver history of CPS involvement, history of intimate partner violence, higher CAP level of concern for abuse, hospital transfer, and near-fatality (all P < .05). The difference in preconsultation referral prevalence for children with public versus private insurance was significant for children with low CAP concern for abuse (52% vs 38%) but not those with higher concern for abuse (73% vs 73%), (P = .023 for interaction of insurance and abuse likelihood category). There were no differences in preconsultation referral based on race or ethnicity. CONCLUSIONS: Biases based on socioeconomic status and social factors may impact decisions to refer to CPS before CAP consultation.

Child traumatic physical abuse rates and comparisons during the COVID-19 pandemic: Retrospective paediatric single institution review in Texas.

AIM: The COVID-19 pandemic drastically altered human behaviour and socialisation and may have created an environment that could lead to increased incidence of domestic abuse and non-accidental trauma, or child physical abuse (CPA). Initial reports about the effect of the COVID-19 pandemic on the rates of CPA have been mixed. The purpose of this study is to describe the effects of COVID-19 on rates of CPA in a large metropolitan paediatric hospital and level I paediatric trauma centre. METHODS: We identified and compared all CPA admissions under 18 years from May 2019 to February 2020 and considered that to be the pre-COVID time frame. The ensuing 12-month period of March 2020 to February 2021 was considered to be the intra-COVID time frame. RESULTS: There were 49 (0.32%) unique CPA patients pre-COVID and 83 (0.85%) unique CPA patients intra-COVID (P < 0.001) with lower total admissions for any reason during the intra-COVID time frame. Monthly CPA cases were increased (P < 0.03) during the intra-COVID time period (mean 6.9, 95% confidence interval: 5.8-12.7) compared to the pre-COVID time period (mean 4.9, 95% confidence interval: 3.3-8.2). CONCLUSION: During the COVID-19 pandemic, there were decreased overall hospital admissions in the period of mandated shutdowns and isolation. However, we saw an increased rate of CPA admissions compared to the time period prior to the pandemic. Knowledge of such data, trends and circumstances will help keep health-care providers alert and vigilant in identifying children at risk for maltreatment, and may impact child abuse protocols and guidelines.

Financing pediatric hospital child abuse teams in 2015: National survey results.

BACKGROUND: Data available on the economics of medical child protection teams stems from prior surveys delivered in 2008 and 2012. OBJECTIVE: The objective was to describe the current financing strategies of medical child maltreatment groups for benchmarking purposes. Additionally, we aimed to quantify often difficult to measure child abuse services that provide value to pediatric hospitals. PARTICIPANTS AND SETTING: In 2017, a 115-item survey was distributed to 230 pediatric hospitals inquiring about child abuse services for the 2015 calendar year. METHODS: The financial topics including budget, revenue, reimbursement, expenses, research, education, and community partnership were analyzed using descriptive statistics. Previous data from similar surveys deployed in 2008 and 2012 were used when applicable to formulate trends. RESULTS: One hundred and thirteen children's hospitals responded comprising a response rate of 49 %. One hundred and four hospitals provided child abuse services at some level. Sixty-two programs (26 %) responded to items about budget. Overall, average team operating budgets increased from $1.15 million in 2008 to $1.4 million in 2015. Few clinical services rendered received full reimbursement. Valuable non-clinical services were poorly reimbursed. An average of 5.45 funding sources were used to supplement remunerations. CONCLUSION: Child maltreatment teams within pediatric hospitals provide services that are largely unfunded as they are not currently recognized by healthcare payment models. These specialists perform a variety of clinical and non-clinical responsibilities that are critical to the care of this population while relying on a variety of funding sources to support their efforts.

Development of the Red Flag Scorecard Screening Tool for Identification of Child Physical Abuse in the Emergency Department.

BACKGROUND: Child physical abuse (CPA) may have subtle presenting signs and can be challenging to identify, especially at emergency centers that do not treat many children. The purpose of this study is to determine the performance of a simple CPA screening tool to identify children most at risk. METHODS: A screening tool ("Red Flag Scorecard") was developed utilizing available evidence-based presenting findings and expert consensus. Retrospective chart review of children treated for injuries between 2014 and 2018 with suspected or confirmed CPA at a level I pediatric trauma center was then performed to validate the screening tool. Descriptive statistics and chi square tests were used to analyze the data. RESULTS: Of 408 cases, median age was 7 months and 60% were male. The majority (69%) were under 1 year of age. The most common history finding was delay in seeking care (58%, 236/408; p = <0.0001), the most common physical exam finding was bruising located away from bony prominences (45%, 182/408), and the most common imaging finding was unexplained brain injury (49%, 201/408). The majority, 84% (343/408), had at least 2 history findings. The combination score of at least 2 history findings and 1 physical/imaging finding was most sensitive (79%). The scorecard would have identified 94% of children who presented with no trauma history (198/211). CONCLUSION: The Red Flag Scorecard may serve as a quick and effective screening tool to raise suspicion for child physical abuse in emergency centers. Prospective study is planned to validate these results. LEVEL OF EVIDENCE: IV.

Understanding Bilateral Skull Fractures in Infancy: A Retrospective Multicenter Case Review.

BACKGROUND: Bilateral skull fractures in infancy often raise suspicion for abuse. Nevertheless, literature suggests that they may occur accidentally. However, empiric data are lacking. OBJECTIVE: This multicenter retrospective review aimed to characterize bilateral skull fractures in a large sample. PARTICIPANTS AND SETTING: Medical records for infants younger than 24 months with bilateral skull fractures involving hospital consultation with a child abuse pediatrician (CAP) were reviewed from 2005 to 2020 at 13 nationally represented institutions. METHODS: Standardized data collection across institutions included historical features, fracture characteristics, and additional injuries, as well as the CAP's determination of accident versus abuse. Pooled data were analyzed for descriptive and bivariate analyses. RESULTS: For 235 cases, 141 were accidental, and 94 abuse. The majority occurred in young infants, and a history of a fall was common in 70% of cases. More than 80% involved both parietal bones. Bilateral simple linear fractures were more common in accidental cases, 79% versus 35%, whereas a complex fracture was more frequent in abuse cases, 55% versus 21% ( P < 0.001). Almost two thirds of accidental cases showed approximation of the fractures at the sagittal suture, compared with one third of abuse cases ( P < 0.001). Whereas focal intracranial hemorrhage was seen in 43% of all cases, diffuse intracranial hemorrhage was seen more in abuse cases (45%) than accidents (11%). Skin trauma was more common in abusive than accidental injury (67% vs 17%, P < 0.001), as were additional fractures on skeletal survey (49% vs 3%, P < 0.001). CONCLUSIONS: A fall history was common in bilateral skull fractures deemed accidental by a CAP. Most accidental cases involved young infants with biparietal simple linear fractures, without skin trauma or additional fractures. A skeletal survey may aid in the determination of accidental or abusive injury for unwitnessed events resulting in bilateral skull fractures in infants.

Child Abuse Pediatrics Research Network: The CAPNET Core Data Project.

OBJECTIVE: Examine the epidemiology of subspecialty physical abuse evaluations within CAPNET, a multicenter child abuse pediatrics research network. METHODS: We conducted a cross-sectional study of children <10 years old who underwent an evaluation (in-person or remote) by a child abuse pediatrician (CAP) due to concerns for physical abuse at ten CAPNET hospital systems from February 2021 through December 2021. RESULTS: Among 3667 patients with 3721 encounters, 69.4% were <3 years old; 44.3% <1 year old, 59.1% male; 27.1% Black; 57.8% White, 17.0% Hispanic; and 71.0 % had public insurance. The highest level of care was outpatient/emergency department in 60.7%, inpatient unit in 28.0% and intensive care in 11.4%. CAPs performed 79.1% in-person consultations and 20.9% remote consultations. Overall, the most frequent injuries were bruises (35.2%), fractures (29.0%), and traumatic brain injuries (TBI) (16.2%). Abdominal (1.2%) and spine injuries (1.6%) were uncommon. TBI was diagnosed in 30.6% of infants but only 8.4% of 1-year old children. In 68.2% of cases a report to child protective services (CPS) was made prior to CAP consultation; in 12.4% a report was made after CAP consultation. CAPs reported no concern for abuse in 43.0% of cases and mild/intermediate concern in 22.3%. Only 14.2% were categorized as definite abuse. CONCLUSION: Most children in CAPNET were <3 years old with bruises, fractures, or intracranial injuries. CPS reports were frequently made prior to CAP consultation. CAPs had a low level of concern for abuse in majority of cases.

The CAPNET multi-center data set for child physical abuse: Rationale, methods and scope.

BACKGROUND: The pediatric subspecialty of Child Abuse Pediatrics (CAP) was certified by the American Board of Medical Subspecialties in 2006. Relative to its impact on pediatric health, CAP-focused research has been relatively under-funded. Multi-center networks related to CAP-focused research have made important advances, but have been limited in scope and duration. CAPNET is multi-center network whose mission is to support CAP-focused research. OBJECTIVE: To describe the rationale, development, and scope of the CAPNET research network infrastructure, the CAPNET data registry and associated data resources. METHODS: Based on existing priorities for CAP-focused research, we used consensus building and iterative testing to establish inclusion criteria, common data elements, data quality assurance, and data sharing processes for children with concerns of physical abuse. RESULTS: We describe the rationale, methods and intended scope for the development of the CAPNET research network and data registry. CAPNET is currently abstracting data for children <10 years (120 months) old who undergo sub-specialty evaluation for physical abuse at 10 US pediatric centers (approximately 4000 evaluations/year total) using an online data capture form. Data domains include: demographics; visit timing and providers, medical/social history, presentation, examination findings, laboratory and radiographic testing, diagnoses, outcomes, and data for contact children. We describe the methods and criteria for collecting and validating data which are broadly available to CAP investigators. CONCLUSIONS: CAPNET represents a new data resource for the CAP research community and will increase the quantity and quality of CAP-focused research.

Timely recognition of retinal hemorrhage in pediatric abusive head trauma evaluation.

BACKGROUND: Distinct patterns of retinal hemorrhages (RHs) are suggestive of abusive head trauma in the context of unexplained intracranial injury. Current recommendations encourage an eye examination within 48 hours of admission due to the rapid resolution of RH. The purpose of this study was to identify clinical factors associated with a delay in funduscopic examination outside the recommended 48 hours. METHODS: Retrospective chart review was completed on all inpatient consultations by the Child Protection Team with evidence of intracranial injury on computed tomography or magnetic resonance imaging over 3 years at a large children's hospital. Extracted data included demographic characteristics, history of intubation, pediatric intensive care unit (PICU) admission, extraventricular drain placement, seizures, use of vasopressor support, and presence of other injuries. Descriptive statistics were used to describe the patient population, clinical characteristics, and outcomes. Multivariate logistic regression was used to identify factors associated with delayed eye examinations. RESULTS: A total of 203 patients met inclusion criteria. Of those, 39 (19.2%) had a delay in initial funduscopic examination. Multivariate analyses revealed that PICU admission, surgical intervention, and seizure activity were significant predictors of delayed examination after controlling for multiple clinical factors. Neurosurgical consultation was shown to be protective against a delayed examination. CONCLUSIONS: Rapid resolution of RH may occur in child abuse. Prompt ophthalmology examinations and neurosurgery consultation when child abuse is suspected help avoid a delay in diagnosis.

Screening for hemophagocytic lymphohistiocytosis in child abuse evaluations: Twelve years of data.

BACKGROUND: Laboratory evaluation is commonly integrated into evaluation of children with suspected physical abuse to identify occult injury and potential mimics of abuse, including hemophagocytic lymphohistiocytosis (HLH). We evaluated the utility of ferritin in laboratory screening panels for physical abuse. OBJECTIVE(S): To determine if hyperferritinemia is a useful screening marker of HLH in physical abuse diagnostic evaluations. PARTICIPANTS AND SETTING: Children being evaluated for physical abuse at a quaternary pediatric referral and level one trauma center in Houston, Texas. METHODS: We conducted a 12-year (2003 - 2015) retrospective descriptive analysis of all ferritin values obtained as part of routine screening panels for physical child abuse. Medical records were abstracted for patients with ferritin > 500 ng/mL. RESULTS: 2954 ferritin levels were obtained in 3091 encounters for suspected physical abuse (median age 6.5 months, interquartile range 2.3-23.5 months). Elevated ferritin was found in 82/2954 (2.8 %); no child evaluated for physical abuse was found to have HLH (95 % CI: 0-4.5%). The child abuse team was consulted in 48/82 (58.5 %) of cases, with the final impression being physical abuse in 33/48 (68.8 %). CONCLUSIONS: We found no instances where HLH was identified by institutional screening panels. The inclusion of ferritin in the screening panel was not beneficial. The presence of hyperferritinemia should not cast medical or legal doubt on physical abuse diagnoses when there is a high index of clinical suspicion. Novel hypotheses from case reports and case series should be studied more rigorously before affecting system change.

The first step in an investigation of quantitative ultrasound as a technique for evaluating infant bone strength.

This study's purpose is to evaluate whether bone speed of sound (SOS) data, a parameter of quantitative ultrasound, collected from an infant autopsy sample are comparable to data collected from healthy, living infants. We hypothesize that SOS values obtained from deceased term-born infants will fall within the normal range for healthy, living infants. The study sample consists of 351 deceased infants between the ages of 30 weeks gestation at birth to 1 year postnatal at the time of death receiving autopsies at the Harris County Institute of Forensic Sciences or Texas Children's Hospital in Houston, TX. Various multivariate and univariate statistics were used to examine the relationship between SOS and age, prematurity, and chronic illness. The results of an ANOVA comparing the study sample data to published data from healthy, living infants indicate the SOS data are comparable. Additionally, a MANOVA indicated significant differences in SOS related to prematurity (p = 0.001) and age (p < 0.001). Mean SOS was significantly greater among term-born infants (M = 3065.66, SD =165.05) than premature infants (M = 2969.71, SD =192.72). Age had a significant polynomial (cubic) relationship with SOS for both the premature and term groups (p < 0.001). Results suggest that bone from an infant autopsy sample is an appropriate surrogate to examine the relationship between SOS and determinants of bone strength. Therefore, future research will use this study sample to investigate the relationship between SOS and determinants of bone strength in infants.

Are classic metaphyseal lesions pathognomonic for child abuse? Two cases of motor vehicle collision-related extremity CML and a review of the literature.

Long bone fractures at the infant growth plate, known as classic metaphyseal lesions (CMLs), raise a strong suspicion for abusive injury. CMLs persist as a hallmark for inflicted injury although a handful of documented cases of CMLs created by other, non-abusive mechanisms within various healthcare settings are scattered throughout the past few decades of medical literature. The forces required to sustain a CML are typically defined as a combination of tensile, compressive, or rotational energy applied to the metaphyseal regions of an infant's long bones. Recently, two separate child protection teams each encountered a case of CML discovered after reported motor vehicle collisions (MVC). This provoked a critical appraisal of the medical literature to inform clinical practice regarding MVCs as a potential mechanism for this fracture type and to remind clinicians that there is no single injury pathognomonic for abuse.

The Infant Injury Database: A Tool for the Study of Injury Patterns in Medicolegal Investigations of Child Abuse.

In 2012, the Harris County Institute of Forensic Sciences began prospectively collecting injury data from pediatric autopsies. These data and associated case information from 635 pediatric cases are archived in the Infant Injury Database (IID). This paper introduces the IID to the forensic community and demonstrates its potential utility for child abuse and infant fatality investigations. The database is intended to be a source of evidence-based research for coroners/medical examiners and clinicians in the recognition and diagnosis of child abuse. RR estimates were employed to quantify the relationship between individual autopsy findings to trauma-related and nontrauma-related causes of death. For example, unsurprisingly, the RR of trauma cases with multiple injury types is significantly greater than other causes of death, but the RR results provide a quantitative representation of the relationship. ROC curve modeling of the presence/absence of various injury types performed well at discriminating trauma from other causes of death (AUC = 0.96).

Mechanical properties of infant bone.

Although an understanding of bone material properties is crucial for interpreting and predicting fracture patterns due to injury or defining the effects of disease on bone strength, information about infant bone properties is scant in the literature. In this study we present the mechanical testing results from 47 tibia and 52 rib specimens taken from 53 infant decedents in order to further our understanding of infant bone strength. Bone specimens were imaged using microCT and tested in three-point bending until failure. Extrinsic and intrinsic properties demonstrated an increase in strength and stiffness over the first year of life, while ductility measures remained largely unchanged. Donor race had no effect on the material properties, but tibia bone specimens showed significant sex differences, with the elastic modulus from females being larger than males. When compared to properties from adolescent and adult donors, infant bone is less strong, less stiff, and more ductile.

Hospital Costs and Charges of Discharge Delays in Children Hospitalized for Abuse and Neglect.

OBJECTIVES: Hospitalizations for child maltreatment cases are longer and costlier than hospitalizations for medically similar nonabuse cases. Some discharges are delayed despite medical clearance because of a lack of safe disposition, increasing the cost of hospitalization. We aim to quantify the additional charges and costs of these delays. METHODS: A retrospective chart review evaluated the dates of medical clearance and clinical characteristics of child protection team inpatient consults from 2012 to 2014 at a 595-bed quaternary-care urban hospital. Charges and costs were compared between those with no delay, those with any delay, and those with a delay >1 day. We excluded children who were not admitted, in whom no abuse was suspected, or in whom sexual abuse was suspected absent extragenital injury. RESULTS: Thirty-six percent (134 of 375) of children hospitalized for abuse remained hospitalized after medical clearance and 20.5% (77 of 375) of children were delayed >1 day. Among those who were delayed, the mean number of days delayed was 4.37 (SD ±7.44). Mean charges after medical clearance were $13 647.53 (±$30 172.17), and mean costs after medical clearance were $6521.93 (±$13 975.34). Both charges and costs were markedly right-skewed. Median costs after medical clearance were $1553.64 (interquartile range, $26.10-$5244.20). Cumulatively, 586 total days of delay resulted in excess charges of $1.8 million. CONCLUSIONS: Continued hospitalization beyond medical clearance occurs often and represents a significant cost. Further study is needed to evaluate whether interventions can be targeted at children with characteristics correlated with prolonged discharge delays.

At-risk children of at-risk parents: assessing common injuries to the children of teenage parents.

OBJECTIVE: To examine the common injuries in the children of teenage parents seen in the emergency department (ED) of a large level I trauma center. STUDY DESIGN: We used admission records for guarantor age to assess common injuries. RESULTS: The majority of the patients were white, in the care of the mother, and suffered accidental injuries, with bruising and skin marks the most common. Although children born to teenage parents are at an increased risk for child abuse, the rate of abuse in this study sample remained low. Falls and ingested objects were the leading mechanisms of injury in these patients, who were generally evaluated and discharged from the ED. CONCLUSION: This study highlights the common injuries and mechanisms to better understand how injuries are sustained in this unique population. The results of this study can be used for educational purposes both in the ED and in classroom-based parenting classes. Prevention efforts for teenage parents should be geared toward teaching better supervision and improving home safety.
