Examining Cases of Child Physical Abuse Evaluations to Identify Opportunities to Improve Intimate Partner Violence Screening in Pediatric Emergency Departments.

The association between child maltreatment and intimate partner violence (IPV) is well supported. Universal IPV screening has been recommended by the American Academy of Pediatrics and the United States Preventative Task Force, and many children's hospitals have established screening protocols. However, the yield and best screening method in families undergoing a child physical abuse (PA) evaluation have not been fully explored. To determine if there is a discrepancy in IPV disclosures between universal IPV screening completed during pediatric emergency department (PED) triage ("triage screening") and IPV screening by a social worker ("social work screening") in families of children who were evaluated for PA. Caregivers of children who presented to an urban tertiary PED and underwent an evaluation for PA via a child abuse pediatrics consult. A retrospective chart review was completed. Data collection included: caregiver responses to both triage screening and social work screening, interview setting details and participants, the child's injuries, and details of the family's reported IPV experiences. Our study (N = 329) revealed that social work screening produced significantly more positive IPV disclosures than triage screening (14.0% vs. 4.3%, p < .001). Additionally, non-IPV violence concerns were identified in 35.7% (n = 5) of the positive triage screens, whereas social work screens had none. These results highlight the benefits of IPV screening by social work in high-risk scenarios, such as child PA evaluations, regardless of universal IPV screening results. Exploring differences between the two screening methods can inform decisions about screening protocols to improve IPV identification in high-risk populations.

External Validation of the PediBIRN Screening Tool for Abusive Head Trauma in Pediatric Emergency Department Settings.

METHODS: We conducted a retrospective, secondary analysis of an existing, deidentified, prospective data set captured to derive a bruising CDR. Subjects were patients under 3 years with bruising and confirmed acute head trauma. An expert medical panel had previously identified patients with AHT. Measures of the CDR's AHT screening performance (sensitivity, specificity, likelihood ratios) were calculated with 95% confidence intervals (CIs). RESULTS: Expert medical panel members had classified 78 of 117 eligible patients (67%) as AHT, 38 (33%) as non-AHT, and 1 as indeterminate. Excluding the indeterminate case, the PediBIRN-4 demonstrated a sensitivity of 0.96 (95% CI, 0.88-0.99), specificity of 0.29 (95% CI, 0.16-0.46), positive likelihood ratio of 1.35 (95% CI, 1.10-1.67), and negative likelihood ratio of 0.13 (95% CI, 0.04-0.46). Close inspection of the data revealed that 1 of the CDR's predictor variables had lowered specificity without impacting sensitivity. Eliminating this variable would have increased specificity to 0.84 (95% CI, 0.68-0.93). CONCLUSIONS: The PediBIRN 4-variable CDR demonstrated AHT screening sensitivity in the pediatric ED equivalent to pediatric intensive care unit and other inpatient settings, but lower specificity. Further study of a simplified 3-variable PediBIRN AHT screening tool for the ED setting is warranted.

Validation of a Clinical Decision Rule to Predict Abuse in Young Children Based on Bruising Characteristics.

Importance: Bruising caused by physical abuse is the most common antecedent injury to be overlooked or misdiagnosed as nonabusive before an abuse-related fatality or near-fatality in a young child. Bruising occurs from both nonabuse and abuse, but differences identified by a clinical decision rule may allow improved and earlier recognition of the abused child. Objective: To refine and validate a previously derived bruising clinical decision rule (BCDR), the TEN-4 (bruising to torso, ear, or neck or any bruising on an infant <4.99 months of age), for identifying children at risk of having been physically abused. Design, Setting, and Participants: This prospective cross-sectional study was conducted from December 1, 2011, to March 31, 2016, at emergency departments of 5 urban children's hospitals. Children younger than 4 years with bruising were identified through deliberate examination. Statistical analysis was completed in June 2020. Exposures: Bruising characteristics in 34 discrete body regions, patterned bruising, cumulative bruise counts, and patient's age. The BCDR was refined and validated based on these variables using binary recursive partitioning analysis. Main Outcomes and Measures: Injury from abusive vs nonabusive trauma was determined by the consensus judgment of a multidisciplinary expert panel. Results: A total of 21 123 children were consecutively screened for bruising, and 2161 patients (mean [SD] age, 2.1 [1.1] years; 1296 [60%] male; 1785 [83%] White; 1484 [69%] non-Hispanic/Latino) were enrolled. The expert panel achieved consensus on 2123 patients (98%), classifying 410 (19%) as abuse and 1713 (79%) as nonabuse. A classification tree was fit to refine the rule and validated via bootstrap resampling. The resulting BCDR was 95.6% (95% CI, 93.0%-97.3%) sensitive and 87.1% (95% CI, 85.4%-88.6%) specific for distinguishing abuse from nonabusive trauma based on body region bruised (torso, ear, neck, frenulum, angle of jaw, cheeks [fleshy], eyelids, and subconjunctivae), bruising anywhere on an infant 4.99 months and younger, or patterned bruising (TEN-4-FACESp). Conclusions and Relevance: In this study, an affirmative finding for any of the 3 BCDR TEN-4-FACESp components in children younger than 4 years indicated a potential risk for abuse; these results warrant further evaluation. Clinical application of this tool has the potential to improve recognition of abuse in young children with bruising.

Abusive Head Trauma in Infants and Children.

Abusive head trauma (AHT) remains a significant cause of morbidity and mortality in the pediatric population, especially in young infants. In the past decade, advancements in research have refined medical understanding of the epidemiological, clinical, biomechanical, and pathologic factors comprising the diagnosis, thereby enhancing clinical detection of a challenging diagnostic entity. Failure to recognize AHT and respond appropriately at any step in the process, from medical diagnosis to child protection and legal decision-making, can place children at risk. The American Academy of Pediatrics revises the 2009 policy statement on AHT to incorporate the growing body of knowledge on the topic. Although this statement incorporates some of that growing body of knowledge, it is not a comprehensive exposition of the science. This statement aims to provide pediatric practitioners with general guidance on a complex subject. The Academy recommends that pediatric practitioners remain vigilant for the signs and symptoms of AHT, conduct thorough medical evaluations, consult with pediatric medical subspecialists when necessary, and embrace the challenges and need for strong advocacy on the subject.

Who's Watching the Children? Caregiver Features Associated with Physical Child Abuse versus Accidental Injury.

OBJECTIVE: To compare caregiver features and caregiving arrangements of children with physical abuse vs accidental injuries. STUDY DESIGN: Data came from a prospective, observational, multicenter study investigating bruising and psychosocial characteristics of children younger than 4 years of age. Using logistic regression, we examined how abuse vs accidental injury and severity of injury were associated with caregiver sex, relation to the child, whether caregiving arrangements were different than usual at the time of injury, and length of the main caregiver's relationship with his/her partner. RESULTS: Of 1615 patients, 24% were determined to have been physically abused. Abuse was more likely when a male caregiver was present (OR 3.31, 95% CI 2.38-4.62). When the male was the boyfriend of the mother (or another female caregiver), the odds of abuse were very high (OR 169.2, 95% CI 61.3-614.0). Severe or fatal injuries also were more likely when a male caregiver was present. In contrast, abuse was substantially less likely when a female caregiver was present (OR 0.25, 95% CI 0.17-0.37) with the exception of a female babysitter (OR 3.87, 95% CI 2.15-7.01). Caregiving arrangements that were different than usual and caregiver relationships <1 year were also associated with an increased risk of abuse. CONCLUSIONS: We identified caregiver features associated with physical abuse. In clinical practice, questions regarding caregiver features may improve recognition of the abused child. This information may also inform future abuse prevention strategies.

Yield of Neuroimaging in Infant Physical Abuse Evaluations: Do Infant Age and Injury Type Matter?

BACKGROUND: Neuroimaging can be an important part of the medical workup for children with suspected physical abuse, but there are not specific guidelines on which children should undergo neuroimaging. OBJECTIVE: We sought to evaluate the yield of neuroimaging in children <12 months of age who are undergoing physical abuse evaluations and to determine how the yield varied by age, injuries, and social risk factors. METHODS: This was a retrospective observational study of infants who presented to an urban children's hospital between September 2007 and October 2012, were evaluated by the hospital's child abuse team, and who received skeletal surveys and underwent neuroimaging for suspected physical abuse. Infants who were diagnosed with head trauma before the abuse evaluation were excluded. Logistic regression was used to investigate the relationship between neuroimaging yield and patient age, presenting injury, and social features. RESULTS: Head injuries were identified in 14 of 170 infants (8.2%). The yield was similar in children <6 months of age and children ≥6 months of age (7.5% and 9.4%, respectively; p = 0.674). Infants with bruises and cases involving a delay in seeking care or cases with previous Child Protective Services involvement were more likely to have injuries identified on neuroimaging. Infants with current or past neurologic signs/symptoms were also more likely to have head injuries on neuroimaging (5/17, 29%), although most infants with abnormal neuroimaging findings did not have neurologic signs/symptoms (9/14, 64%). CONCLUSIONS: We found that while certain features were associated with abnormal findings on neuroimaging, infant age (<6 months vs. 6-12 months) was not.

Are negative/unrealistic parent descriptors of infant attributes associated with physical abuse?

Parents' perceptions of child behavior influence their responses to the child and may be important predictors of physical abuse. We examined whether infants 12 months of age or younger who were described with negative or developmentally unrealistic words were more likely than other infants to have been physically abused. As part of a prospective observational multicenter study investigating bruising and familial psychosocial characteristics, parents were asked to (1) describe their child's personality, and (2) list three words to describe their child. Four independent raters coded parent responses using a qualitative content analysis, identifying descriptors of infants and classifying each as positive, neutral, or negative/unrealistic. A medical expert panel, blinded to the psychosocial data, separately categorized each case as abuse or accident. We then analyzed the potential association between negative/unrealistic descriptors and abusive injury. Of 185 children enrolled, 147 cases (79%) were categorized as accident and 38 (21%) as abuse. Parents used at least one negative/unrealistic descriptor in 35/185 cases (19%), while the remaining 150 cases (81%) included only positive or neutral descriptors. Of the infants described with negative/unrealistic words, 60% were abused, compared to 11% of those described with positive or neutral words (p < .0001; age group-adjusted OR = 9.95; 95% confidence interval [3.98, 24.90]). Though limited by sample-size, this pilot study informs future work to create a screening tool utilizing negative/unrealistic descriptors in combination with other predictive factors to identify infants at high risk for physical child abuse.

Enlarged subarachnoid spaces and intracranial hemorrhage in children with accidental head trauma.

OBJECTIVE Benign external hydrocephalus (BEH) is an enlargement of the subarachnoid spaces (SASs) that can be seen in young children. It is controversial whether children with BEH are predisposed to developing subdural hemorrhage (SDH) with or without trauma. This issue is clinically relevant as a finding of unexplained SDH raises concerns about child abuse and often prompts child protection and law enforcement investigations. METHODS This retrospective study included children (1-24 months of age) who underwent head CT scanning after an accidental fall of less than 6 feet. Head CT scans were reviewed, cranial findings were documented, and the SAS was measured and qualitatively evaluated. Enlarged SAS was defined as an extraaxial space (EAS) greater than 4 mm on CT scans. Clinical measurements of head circumference (HC) were noted, and the head circumference percentile was calculated. The relationship between enlarged SAS and HC percentile, and enlarged SAS and intracranial hemorrhage (ICH), were investigated using bivariate analysis. RESULTS Of the 110 children included in this sample, 23 had EASs greater than 4 mm. The mean patient age was 6.8 months (median 6.0 months). Thirty-four patients (30.9%) had ICHs, including subarachnoid/subpial (6.2%), subdural (6.2%), epidural (5.0%), and unspecified extraaxial hemorrhage (16.5%). Enlarged SAS was positively associated with subarachnoid/subpial hemorrhage; there was no association between enlarged SASs and either SDH or epidural hemorrhage. A larger SAS was positively associated with larger HC percentile; however, HC percentile was not independently associated with ICH. CONCLUSIONS Enlarged SAS was not associated with SDH, but was associated with other ICHs. The authors' findings do not support the theory that BEH predisposes children to SDH with minor accidental trauma.
