Racial and ethnic disparities in diagnostic imaging for child physical abuse.

IMPORTANCE: Racial bias may affect occult injury testing decisions for children with concern for abuse. OBJECTIVES: To determine the association of race on occult injury testing decisions at children's hospitals. DESIGN: In this retrospective study, we measured disparities in: (1) the proportion of visits for which indicated diagnostic imaging studies for child abuse were obtained; (2) the proportion of positive tests. SETTING: The Pediatric Health Information System (PHIS) administrative database encompassing 49 tertiary children's hospitals during 2017-2019. PARTICIPANTS: We built three cohorts based on guidelines for diagnostic testing for child abuse: infants with traumatic brain injury (TBI; n = 1952), children <2 years old with extremity fracture (n = 20,842), and children <2 years old who received a skeletal survey (SS; n = 13,081). MAIN OUTCOMES AND MEASURES: For each group we measured: (1) the odds of receiving a specific guideline-recommended diagnostic imaging study; (2) among those with the indicated imaging study, the odds of an abuse-related injury diagnosis. We calculated both unadjusted and adjusted odds ratios (AOR) by race and ethnicity, adjusting for sex, age in months, payor, and hospital. RESULTS: In infants with TBI, the odds of receiving a SS did not differ by racial group. Among those with a SS, the odds of rib fracture were higher for non-Hispanic Black than Hispanic (AOR 2.05 (CI 1.31, 3.2)) and non-Hispanic White (AOR 1.57 (CI 1.11, 2.32)) patients. In children with extremity fractures, the odds of receiving a SS were higher for non-Hispanic Black than Hispanic and non-Hispanic White patients (AOR 1.97 (CI 1.74, 2.23)); (AOR 1.17 (CI 1.05, 1.31)), respectively, and lower for Hispanic than non-Hispanic White patients (AOR 0.59 (CI 0.53, 0.67)). Among those receiving a SS, the rate of rib fractures did not differ by race. In children with skeletal surveys, the odds of receiving neuroimaging did not differ by race. Among those with neuroimaging, the odds of a non-fracture, non-concussion TBI were lower in non-Hispanic Black than Hispanic patients (AOR 0.7 (CI 0.57, 0.86)) and were higher among Hispanic than non-Hispanic White patients (AOR 1.23 (CI 1.02, 1.47)). CONCLUSIONS AND RELEVANCE: We did not identify a consistent pattern of race-based disparities in occult injury testing when considering the concurrent yield for abuse-related injuries.

A lucid interval in a victim of abusive head trauma with multiple parenchymal lacerations.

Abusive head trauma (AHT) is a leading cause of abusive deaths in children under age one. AHT can include intracranial hemorrhages, hypoxic ischemic injury, or parenchymal lacerations. Most infants with parenchymal lacerations present with acute neurological symptoms. There has been some published literature on lucid intervals in cases of AHT; however, there has not been a described lucid interval with parenchymal lacerations. Parenchymal lacerations typically present with acute symptomatology such as seizures, alteration in mental status, or increased fussiness/lethargy given the damage to neurons and brain structure. We present a case of a healthy 2-month-old who ultimately was diagnosed with AHT and three parenchymal lacerations and had a 2.5 hour period of normal neurological status prior to acute decompensation.

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.

Examining diagnostic variability among pediatric subspecialists using case examples of infant head injury.

BACKGROUND: Although there is research regarding the diagnosis and timing of abusive head trauma, there remains practice variation among pediatric subspecialists. OBJECTIVES: To examine diagnostic variability among pediatric subspecialists using case examples of infant head injury. Secondary objectives were timing variability among subspecialists, and diagnostic and timing variability among Child Abuse Pediatricians (CAPs). PARTICIPANTS AND SETTING: Pediatric subspecialists were recruited from Child Abuse Pediatrics, Hospital Medicine, Emergency Medicine, Critical Care, and Neurosurgery to complete a research instrument. Participants qualified for the study if they evaluated at least 1 case of possible abusive head trauma during their career. METHODS: This multi-institutional, mixed-methods study used a research instrument with 4 case examples of infant head injury: severe retinal hemorrhages (RH), mass-effect subdural hemorrhage (SDH), SDH membrane formation, and sepsis. The response selected by most CAPs was reference and compared across subspecialties and among CAPs using Chi-square or Fisher's exact tests. A Bonferroni correction (p < 0.01) was used for subspecialty comparisons. RESULTS: There were 288 participants who completed at least 1 case example. Diagnostic variability was observed in all case examples. Significantly fewer Hospital Medicine (34.9 % vs. 57.9 %, p < 0.01), Emergency Medicine (28.0 % vs. 57.9 %, p < 0.0001), and Neurosurgery (24.0 % vs. 57.9 %, p < 0.01) participants selected the reference response for the mass-effect SDH case example. Timing variability was statistically significant for all case examples (p < 0.01). Significantly fewer CAPs aged 44-64 years selected the reference response for timing (p < 0.01) for the severe RH case example. CONCLUSIONS: Additional peer review processes and consensus guidelines for challenging issues in abusive head trauma may be beneficial.

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.

Diagnostic testing for and detection of physical abuse in infants with brief resolved unexplained events.

BACKGROUND: A Brief Resolved Unexplained Event (BRUE) can be a sign of occult physical abuse. OBJECTIVES: To identify rates of diagnostic testing able to detect physical abuse (head imaging, skeletal survey, and liver transaminases) at BRUE presentation. The secondary objective was to estimate the rate of physical abuse diagnosed at initial BRUE presentation through 1 year of age. PARTICIPANTS AND SETTING: Infants who presented with a BRUE at one of 15 academic or community hospitals were followed from initial BRUE presentation until 1 year of age for BRUE recurrence or revisits. METHODS: This study was part of the BRUE Research and Quality Improvement Network, a multicenter retrospective cohort examining infants with BRUE. Generalized estimating equations assessed associations with performance of diagnostic testing (adjusted odds ratio (aOR)). RESULTS: Of the 2036 infants presenting with a BRUE, 6.2 % underwent head imaging, 7.0 % skeletal survey, and 12.1 % liver transaminases. Infants were more likely to undergo skeletal survey if there were physical examination findings concerning for trauma (aOR 8.23, 95 % CI [1.92, 35.24], p < 0.005) or concerning social history (aOR 1.89, 95 % CI [1.13, 3.16], p = 0.015). There were 7 (0.3 %) infants diagnosed with physical abuse: one at BRUE presentation, one <3 days after BRUE presentation, and five >30 days after BRUE presentation. CONCLUSION: There were low rates of diagnostic testing and physical abuse identified in infants presenting with BRUE. Further study including standardized testing protocols is warranted to identify physical abuse in infants presenting with a BRUE.

Evaluation for Bleeding Disorders in Suspected Child Abuse.

Bruising or bleeding in a child can raise the concern for child abuse. Assessing whether the findings are the result of trauma and/or whether the child has a bleeding disorder is critical. Many bleeding disorders are rare, and not every child with bruising/bleeding that may raise a concern for abuse requires an evaluation for bleeding disorders. However, in some instances, bleeding disorders can present in a manner similar to child abuse. Bleeding disorders cannot be ruled out solely on the basis of patient and family history, no matter how extensive. The history and clinical evaluation can be used to determine the necessity of an evaluation for a possible bleeding disorder, and prevalence and known clinical presentations of individual bleeding disorders can be used to guide the extent of laboratory testing. This clinical report provides guidance to pediatricians and other clinicians regarding the evaluation for bleeding disorders when child abuse is suspected.

Evaluating for Suspected Child Abuse: Conditions That Predispose to Bleeding.

Child abuse might be suspected when children present with cutaneous bruising, intracranial hemorrhage, or other manifestations of bleeding. In these cases, it is necessary to consider medical conditions that predispose to easy bleeding or bruising. When evaluating for the possibility of bleeding disorders and other conditions that predispose to hemorrhage, it is important for pediatricians to consider the child's presenting history, medical history, and physical examination findings before initiating a laboratory investigation. Many medical conditions can predispose to easy bleeding. Before ordering laboratory tests for a disease, it is useful to understand the biochemical basis and clinical presentation of the disorder, condition prevalence, and test characteristics. This technical report reviews the major medical conditions that predispose to bruising or bleeding and should be considered when evaluating for abusive injury.

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.

Differences Between Viral Meningitis and Abusive Head Trauma.

OBJECTIVES: To evaluate the hypothesis that viral meningitis may mimic abusive head trauma (AHT) by comparing the history of present illness (HPI) and clinical presentation of young children with proven viral meningitis to those with AHT and those with subdural hemorrhage (SDH) only. We hypothesized that significant differences would exist between viral meningitis and the comparison groups. METHODS: We performed a 5-year retrospective case-control study of subjects aged <2 years, comparing those with confirmed viral meningitis (controls) to those with SDH evaluated by the hospital child abuse pediatrics team (cases). Cases were classified as SDH with concomitant suspicious injuries (AHT) and without concomitant suspicious injuries (SDH-only). Groups were compared across demographic (5 measures), HPI (11 measures), and clinical (9 measures) domains. Odds ratios were calculated for measures within each domain. RESULTS: Of 550 subjects, there were 397 viral meningitis, 118 AHT, and 35 SDH-only subjects. Viral meningitis differed significantly from AHT subjects on all demographic measures, and from SDH-only subjects on age. Viral meningitis differed significantly from AHT subjects in all HPI measures with odds ratios ranging from 2.7 to 322.5, and from SDH-only subjects in 9 HPI measures with odds ratios ranging from 4.6 to 485.2. In the clinical domain, viral meningitis differed significantly from AHT subjects in all measures, with odds ratios ranging from 2.5 to 74.0, and from SDH-only subjects in 5 measures with odds ratios ranging from 2.9 to 16.8. CONCLUSIONS: Viral meningitis is not supported as a mimic of AHT.

State Spending on Public Benefit Programs and Child Maltreatment.

BACKGROUND: To determine the association between states' total spending on benefit programs and child maltreatment outcomes. METHODS: This was an ecological study of all US states during federal fiscal years 2010-2017. The primary predictor was states' total annual spending on local, state, and federal benefit programs per person living ≤100% federal poverty limit, which was the sum of (1) cash, housing, and in-kind assistance, (2) housing infrastructure, (3) child care assistance, (4) refundable Earned Income Tax Credit, and (5) Medical Assistance Programs. The main outcomes were rates of maltreatment reporting, substantiations, foster care placements, and fatalities after adjustment for relevant confounders. Generalized estimating equations adjusted for federal spending and estimated adjusted incidence rate ratios (IRRs) and 95% confidence intervals (CIs). RESULTS: States' total spending was inversely associated with all maltreatment outcomes. For each additional $1000 states spent on benefit programs per person living in poverty, there was an associated -4.3% (adjusted IRR: 0.9573 [95% CI: 0.9486 to 0.9661]) difference in reporting, -4.0% (adjusted IRR: 0.903 [95% CI: 0.9534 to 0.9672]) difference in substantiations, -2.1% (adjusted IRR: 0.9795 [95% CI: 0.9759 to 0.9832]) difference in foster care placements, and -7.7% (adjusted IRR: 0.9229 [95% CI: 0.9128 to 0.9330]) difference in fatalities. In 2017, extrapolating $1000 of additional spending for each person living in poverty ($46.5 billion nationally, or 13.3% increase) might have resulted in 181 850 fewer reports, 28 575 fewer substantiations, 4168 fewer foster care placements, and 130 fewer fatalities. CONCLUSIONS: State spending on benefit programs was associated with reductions in child maltreatment, which might offset some benefit program costs.

A System-Wide Hospital Child Maltreatment Patient Safety Program.

BACKGROUND AND OBJECTIVES: Hospital-wide patient safety programs have been used to ensure appropriate provision of care. Similar approaches have not been widely applied to child maltreatment. In this study, we describe a hospital-system child maltreatment safety program by characterizing the frequency of patients needing further intervention, associations between the age of patient and location of care and need for further intervention, and patients who require immediate intervention. METHODS: For all staff concerns for child maltreatment, a social worker completed a patient at risk (PAR) form. All PAR forms were reviewed within 24 hours by the child abuse team and categorized on the basis of 6 types of interventions, most significantly an "immediate callback." Wilcoxon rank and χ2 tests were used for group comparisons. RESULTS: Over a 30-month period, program interventions occurred in 2061 of 7698 PARs (26.8%). The most common reason for a PAR form was physical abuse (32.5%). Subjects requiring an intervention were no different in age than those who did not (median age: 5.6 vs 5.2 years). PAR forms performed in the emergency departments or urgent care were more likely to require an intervention than inpatient (odds ratio: 4.4; 95% confidence interval 3.6-5.3) or clinic (odds ratio: 2.0; 95% confidence interval 1.7-2.3) PAR forms. Of the 53 immediate callbacks, potential diagnostic errors and safe discharge concerns occurred in nearly one-half, and >40% involved subjects with bruising. Immediate follow-up in the child abuse pediatrician clinic occurred in 87% (46 of 53) of cases, resulting in a new or changed diagnosis in 57% of such cases. CONCLUSIONS: A child maltreatment safety program encompassing a health system can identify and address medical errors.

Association of routine school closures with child maltreatment reporting and substantiation in the United States; 2010-2017.

BACKGROUND: There exists a presumption that school closures lead to a diminished capacity to detect child maltreatment, but empiric evidence is lacking. OBJECTIVE: To determine if child maltreatment reporting and substantiation differ between periods when schools are routinely closed compared to in session. PARTICIPANTS AND SETTING: Child maltreatment reporting and substantiation among all U.S. States and the District of Columbia from January 1, 2010 through December 31, 2017. METHODS: Two-week intervals during periods of routine school closure (early January, June through mid-August, late November, and late December) were compared to all other 2-week intervals. Negative binomial generalized estimating equations compared rates of reporting and substantiation, resulting in incidence rate ratios (IRR) with 95% confidence intervals (CI). RESULTS: Compared to when school was in session, reporting was 16.0% (IRR 0.84 [95% CI: 0.83, 0.85]) lower during school closures and substantiations were 12.3% (IRR 0.88 [95% CI: 0.86, 0.89]) lower. The largest reductions in reporting were observed among education personnel (-42.1%; IRR 0.58 [95% CI: 0.54, 0.62]), children aged 5-17 years (-18.6%; IRR 0.81 [95% CI: 0.80, 0.83), and for physical abuse (-19.6%; IRR 0.80 [95% CI: 0.79, 0.82]). Reductions during closure periods were not matched by increases during two-week intervals immediately following closure periods. CONCLUSIONS: Results suggest that the detection of child maltreatment may be diminished during periods of routine school closure. Findings may inform prevention planning and risk-benefit analyses for future school closures. Further study should disentangle the issue of decreased detection versus decreased prevalence of maltreatment during school closures.

A review on clotting disorders and retinal hemorrhages: Can they mimic abuse?

BACKGROUND: The characteristic findings of abusive head trauma (AHT) include retinal hemorrhages (RH). RH have many etiologies in childhood, which should be considered in the differential diagnosis of possible child abuse. The relationship between RH and thrombophilia in children is not well established. OBJECTIVE: In this literature review, we sought to assess whether retinal findings in pediatric patients with thrombophilia could mimic those of AHT. METHODS: A literature search was performed to identify all cases of thrombophilia in children less than 18 years old with ocular manifestations. Disorders of thrombophilia including protein C and S deficiency, factor V Leiden (FVL), prothrombin variant, MTHFR mutation, hyperhomocysteinemia, elevated factor VIII, and elevated lipoprotein (a) were considered. All cases of pediatric thrombophilia with retinal examination or intraocular bleeding were included. If provided, descriptions of the RH were reviewed. RESULTS: Our initial search yielded 514 results. Forty-three articles met our inclusion criteria. We identified 3 children with RH within the AHT usual age range (<5 years old), ages 5 weeks and 7 weeks old, in the setting of thrombophilia. One child had ocular findings that could potentially mimic abuse. No other indicators of abuse were present in this case. CONCLUSIONS: Based on previous reports, thrombophilia alone has not been shown to clearly mimic abusive head trauma. In reported cases of thrombophilia with RH, the clinical picture and ophthalmic findings are usually distinct from abuse.

Subdural hemorrhage in a cohort with cerebral sinovenous thrombosis: Application to abusive head trauma.

BACKGROUND: Cerebral sinovenous thrombosis (CSVT) is a postulated cause of subdural hemorrhage (SDH) that is hypothesized to mimic abusive head trauma (AHT). Minimal data exists directly investigating this relationship. OBJECTIVES: To evaluate the frequency of SDH in children with CSVT, identify factors associated with CSVT and SDH, and to assess if any association supports the hypothesis that CSVT causes SDH. PARTICIPANTS AND SETTING: The International Pediatric Stroke Study (IPSS) prospectively collects data on subjects birth to 19 years of age with intracranial thrombosis. METHODS: IPSS subjects with CSVT and SDH were compared to those with CSVT and no SDH. For subjects with CSVT and SDH, neuroimaging reports further characterized the findings. In any case with no known risk factors for SDH, neuroimaging studies were reviewed by a pediatric neuroradiologist. RESULTS: Of 216 subjects with CSVT, 20 (9.3%) had SDH. Those with SDH (median age 0.3 years) were younger than those without SDH (median age 4.2 years), p < 0.001. Subjects with CSVT and SDH more frequently had anoxia (OR = 10.8; 95% CI: 1.4, 81.1), head/neck injury (OR = 4.0; 95% CI: 1.3, 12.6), or abnormal consciousness (OR = 3.0; 95% CI: 1.2, 7.6). Of 20 subjects with CSVT and SDH, 19 had known risk factors for SDH. The remaining subject had a chronic SDH identified concomitantly to a newly symptomatic CSVT with accompanying venous infarctions. CONCLUSIONS: SDH in the setting of CSVT is typically identified in children with independent risk factors for SDH. This study does not support the hypothesis that CSVT causes SDH.

Retinal hemorrhage and bleeding disorders in children: A review.

BACKGROUND: Retinal hemorrhages (RH) are a common manifestation of abusive head trauma (AHT) resulting from acceleration-deceleration injury with or without blunt impact. Evaluation of a child with RH requires careful consideration of these differential diagnoses. The extent to which coagulopathy alone can cause RH would be useful to understand as coagulopathy may accompany AHT. OBJECTIVE: In this systematic review, we sought to identify whether coagulopathies have been reported with RH similar to those of AHT. METHODS: We performed a literature search for ocular manifestations of bleeding disorders in children less than 18 years old. We included clotting factor deficiencies, vitamin K deficiency, platelet function abnormalities, thrombocytopenia, disseminated intravascular coagulation (DIC), and trauma induced coagulopathy (TIC). We included only pediatric reports of intraocular bleeding or documented eye examinations that indicated no hemorrhages. We then re-examined cases for ocular and systemic findings that could potentially mimic abuse. RESULTS: Our initial search yielded 816 results. Sixty-one articles met our inclusion criteria. Of these, there were 32 children within the AHT age range (less than 5 years old) who had RH and concomitant coagulopathy. Only 5 cases might potentially be confused for abuse. Of these, no classic characteristics of RH from abuse such as retinoschisis or retinal folds were found. Systemic features were inconsistent with AHT. CONCLUSIONS: The presence of coagulopathy alone does not rule out the possibility that the child has been abused. Coagulopathy alone has not been reported as an etiology of RH that are consistent with AHT, especially when other findings are present.

Cervical Spine Imaging and Injuries in Young Children With Non-Motor Vehicle Crash-Associated Traumatic Brain Injury.

OBJECTIVES: The aim of this study was to evaluate cervical magnetic resonance imaging (MRI) and computed tomography (CT) practices and cervical spine injuries among young children with non-motor vehicle crash (MVC)-associated traumatic brain injury (TBI). METHODS: We performed a retrospective study of a stratified, systematic random sample of 328 children younger than 2 years with non-MVC-associated TBI at 4 urban children's hospitals from 2008 to 2012. We defined TBI etiology as accidental, indeterminate, or abuse. We reported the proportion, by etiology, who underwent cervical MRI or CT, and had cervical abnormalities identified. RESULTS: Of children with non-MVC-associated TBI, 39.4% had abusive head trauma (AHT), 52.2% had accidental TBI, and in 8.4% the etiology was indeterminate. Advanced cervical imaging (CT and/or MRI) was obtained in 19.1% of all children with TBI, with 9.3% undergoing MRI and 11.7% undergoing CT. Cervical MRI or CT was performed in 30.9% of children with AHT, in 11.7% of accidental TBI, and in 10.7% of indeterminate-cause TBI. Among children imaged by MRI or CT, abnormal cervical findings were found in 22.1%, including 31.3% of children with AHT, 7.1% of children with accidental TBI, and 0% of children with indeterminate-cause TBI. Children with more severe head injuries who underwent cervical imaging were more likely to have cervical injuries. CONCLUSIONS: Abusive head trauma victims appear to be at increased risk of cervical injuries. Prospective studies are needed to define the risk of cervical injury in children with TBI concerning for AHT and to inform development of imaging guidelines.

Occult head injuries in infants evaluated for physical abuse.

BACKGROUND: Abusive head injuries in infants may be occult but clinically or forensically important. Data conflict regarding yield of neuroimaging in detecting occult head injuries in infants evaluated for physical abuse, with prior studies identifying yields of 4.3-37.3 %. OBJECTIVES: (1) To quantify yield of computed tomography or magnetic resonance imaging in identification of occult head injuries in infants with concerns for physical abuse and (2) to evaluate risk factors for occult head injuries. PARTICIPANTS AND SETTING: We conducted a retrospective, stratified, random systematic sample of 529 infants <12 months evaluated for physical abuse at 4 urban children's hospitals in the United States from 2008-2012. Infants with signs or symptoms suggesting head injury or skull fracture on plain radiography (N = 359), and infants without neuroimaging (N = 1) were excluded. METHODS: Sampling weights were applied to calculate proportions of infants with occult head injuries. We evaluated for associations between hypothesized risk factors (age <6 months, rib or extremity fracture, facial bruising) and occult head injury using chi-square tests. RESULTS: Of 169 neurologically normal infants evaluated for abuse, occult head injury was identified in 6.5 % (95 % CI: 2.6, 15.8). Infants <6 months were at higher risk (9.7 %; 95 % CI: 3.6, 23.3) than infants 6-12 months (1.0 %; 95 % CI: 1.3, 20.2). Rib fracture, extremity fracture and facial bruising were not associated with occult head injury. CONCLUSIONS: Occult head injuries were less frequent than previously reported in some studies, but were identified in 1 in 10 infants <6 months. Clinicians should have a low threshold to obtain neuroimaging in young infants with concern for abuse.

Intrauterine Substance Exposure and the Risk for Subsequent Physical Abuse Hospitalizations.

OBJECTIVE: To describe the relative risk for a physical abuse hospitalization among substance exposed infants (SEI) with and without neonatal abstinence syndrome (NAS). METHODS: We created a nationally representative US birth cohort using the 2013 and 2014 Nationwide Readmissions Databases. International Classification of Diseases, Ninth Revision, Clinical Modification codes were used to identify newborns, predictor variables, and subsequent hospitalizations for physical abuse within 6 months of discharge from newborns' birth hospitalization. Predictor variables included newborn demographics, prematurity or low birth weight, and intrauterine substance exposure: non-SEI, SEI without NAS, and SEI with NAS. Multiple logistic regression calculated adjusted relative risks and 95% confidence intervals. A subanalysis of newborns with narcotic exposure was performed. RESULTS: There were 3,740,582 newborns in the cohort; of which 13,024 (0.4%) were SEI without NAS and 20,196 (0.5%) SEI with NAS. Overall, 1247 (0.03%) newborns were subsequently hospitalized for physical abuse within 6 months. Compared to non-SEI, SEI with NAS (adjusted relative risks: 3.84 [95% confidence intervals: 2.79-5.28]) were at increased risk for having a subsequent hospitalization for physical abuse, but SEI without NAS were not. A similar pattern was observed among narcotic-exposed infants; infants with NAS due to narcotics were at increased risk, but narcotic-exposed infants without NAS were not. CONCLUSIONS: Our results suggest that newborns diagnosed with NAS are at increased risk of physical abuse during early infancy, above that of substance-exposed infants without NAS. These results should improve the identification of higher-risk infants who may benefit from more rigorous safety planning and follow-up care.

Insurance Coverage for Children Impacts Reporting of Child Maltreatment by Healthcare Professionals.

OBJECTIVES: Children's insurance coverage, through increased access and use of the healthcare system, may increase the likelihood that healthcare professionals (HCPs) will detect and report child maltreatment. We sought to estimate the association between insurance coverage for children and reporting of child maltreatment by HCPs. STUDY DESIGN: We conducted a cross-sectional study of US counties from 2008 to 2015 using data from the US Census Bureau's Small Area Health Insurance Estimates, National Center for Health Statistics, and National Child Abuse and Neglect Data System. The primary predictor was counties' percent of children insured. We controlled for counties' children living at ≤200% federal poverty level, race/ethnicity demographics, and urban-rural status. The primary outcome was the rate of maltreatment reporting from HCPs. Generalized linear mixed effects models with repeated measures across years tested associations. RESULTS: We included 5517 county-year observations involving 470 876 018 child-years. Counties' percent of children insured ranged from 74.6% to 99.2% with a median of 93.7% (IQR, 91.0-95.4). For every 1 percentage point increase in counties' percent of children insured, there was an associated 2% increase in child maltreatment reporting by HCPs (adjusted incidence rate ratio, 1.02; 95% CI, 1.02-1.03). If counties' percentage of insured children had been 1 percentage point greater in 2015, a predicted 5620 (95% CI, 5620-8089) additional reports would have been generated. CONCLUSIONS: Among its other benefits for children's well-being, insurance coverage may also contribute to child protection by increasing the reporting of maltreatment among HCPs.
