Can TEN4 distinguish bruises from abuse, inherited bleeding disorders or accidents?

OBJECTIVE: Does TEN4 categorisation of bruises to the torso, ear or neck or any bruise in <4-month-old children differentiate between abuse, accidents or inherited bleeding disorders (IBDs)? DESIGN: Prospective comparative longitudinal study. SETTING: Community. PATIENTS: Children <6 years old. INTERVENTIONS: The number and location of bruises compared for 2568 data collections from 328 children in the community, 1301 from 106 children with IBD and 342 abuse cases. MAIN OUTCOME MEASURES: Likelihood ratios (LRs) for the number of bruises within the TEN and non-TEN locations for pre-mobile and mobile children: abuse vs accidental injury, IBD vs accident, abuse vs IBD. RESULTS: Any bruise in a pre-mobile child was more likely to be from abuse/IBD than accident. The more bruises a pre-mobile child had, the higher the LR for abuse/IBD vs accident. A single bruise in a TEN location in mobile children was not supportive of abuse/IBD. For mobile children with more than one bruise, including at least one in TEN locations, the LR favouring abuse/IBD increased. Applying TEN4 to collections from abused and accidental group <48 months of age with at least one bruise gave estimated sensitivity of 69% and specificity for abuse of 74%. CONCLUSIONS: These data support further child protection investigations of a positive TEN4 screen in any pre-mobile children with a bruise and in mobile children with more than one bruise. TEN4 did not discriminate between IBD and abuse, thus IBD needs to be excluded in these children. Estimated sensitivity and specificity of TEN4 was appreciably lower than previously reported.

Validation of a Prediction Tool for Abusive Head Trauma.

BACKGROUND AND OBJECTIVES: Abusive head trauma (AHT) may be missed in the clinical setting. Clinical prediction tools are used to reduce variability in practice and inform decision-making. From a systematic review and individual patient data analysis we derived the Predicting Abusive Head Trauma (PredAHT) tool, using multilevel logistic regression to predict likelihood of AHT. This study aims to externally validate the PredAHT tool. METHODS: Consecutive children aged <36 months admitted with an intracranial injury, confirmed as abusive or nonabusive, to 2 sites used in the original model were ascertained. Details of 6 influential features were recorded (retinal hemorrhage, rib and long -bone fractures, apnea, seizures, and head or neck bruising). We estimated the likelihood of an unrecorded feature being present with multiple imputation; analysis included sensitivity, specificity, and area under the curve, with 95% confidence intervals (CIs). RESULTS: Data included 133 non-AHT cases and 65 AHT cases, 97% of children were <24 months old. Consistent with original predictions, when ≥3 features were present in a child <36 months old with intracranial injury, the estimated probability of AHT was >81.5% (95% CI, 63.3-91.8). The sensitivity of the tool was 72.3% (95% CI, 60.4-81.7), the specificity was 85.7% (95% CI, 78.8-90.7), area under the curve 0.88 (95% CI, 0.823-0.926). CONCLUSIONS: When tested on novel data, the PredAHT tool performed well. This tool has the potential to contribute to decision-making in these challenging cases. An implementation study is needed to explore its performance and utility within the child protection process.

Bruising in children who are assessed for suspected physical abuse.

OBJECTIVE: To describe the characteristics of bruising and mode of presentation of children referred to the paediatric child protection team with suspected physical abuse (PA), and the extent to which these differ between the children where abuse was confirmed and those where it was excluded. DESIGN: Cross-sectional study. SETTING AND PATIENTS: 519 children, <6 years, referred to two paediatric child protection teams. MAIN OUTCOME MEASURES: The mode of presentation, number, anatomical distribution, size and appearance of bruises according to whether PA was confirmed or excluded. ORs with 95% CI were calculated where relevant. RESULTS: PA was confirmed in 69% of children; the rate varied from 84% when abuse was witnessed, admitted, alleged or where explanation for injury was absent or implausible, to 50% where there was a concerning history. Significantly more children with PA had bruises (89.4%) than PA-excluded (69.9%) and had significantly more sites affected (p<0.001). The odds of a PA child having bruising to: buttocks/genitalia (OR 10.9 (CI 2.6 to 46), left ear (OR 7.10 (CI 2.2 to 23.4), cheeks (Left (OR 5.20 (CI 2.5 to 10.7), Right OR 2.83 (CI 1.5 to 5.4)), neck (OR 3.77 (CI 1.3 to 10.9), trunk (back (OR 2.85 (CI 1.6 to 5.0) front (OR 4.74 (CI 2.2 to 10.2), front of thighs (OR2.48 (CI 1.4 to 4.5) or upper arms (OR 1.90 (CI 1.1 to 3.2) were significantly greater than in children with PA-excluded. Petechiae, linear or bruises with distinct pattern, bruises in clusters, additional injuries or a child known to social services for previous child abuse concerns were significantly more likely in PA. CONCLUSIONS: Features in the presenting history, the extent and pattern of bruising differed between children with confirmed PA and those where abuse was excluded. These findings can provide a deeper understanding of bruising sustained from PA.

Emotional, behavioral, and developmental features indicative of neglect or emotional abuse in preschool children: a systematic review.

IMPORTANCE: Early intervention for neglect or emotional abuse in preschoolers may mitigate lifelong consequences, yet practitioners lack confidence in recognizing these children. OBJECTIVE: To define the emotional, behavioral, and developmental features of neglect or emotional abuse in preschoolers. EVIDENCE REVIEW: A literature search of 18 databases, 6 websites, and supplementary searching performed from January 1, 1960, to February 1, 2011, identified 22 669 abstracts. Standardized critical appraisal of 164 articles was conducted by 2 independent, trained reviewers. Inclusion criteria were children aged 0 to 6 years with confirmed neglect or emotional abuse who had emotional, behavioral, and developmental features recorded or for whom the carer-child interaction was documented. FINDINGS: Twenty-eight case-control (matched for socioeconomic, educational level, and ethnicity), 1 cross-sectional, and 13 cohort studies were included. Key features in the child included the following: aggression (11 studies) exhibited as angry, disruptive behavior, conduct problems, oppositional behavior, and low ego control; withdrawal or passivity (12 studies), including negative self-esteem, anxious or avoidant behavior, poor emotional knowledge, and difficulties in interpreting emotional expressions in others; developmental delay (17 studies), particularly delayed language, cognitive function, and overall development quotient; poor peer interaction (5 studies), showing poor social interactions, unlikely to act to relieve distress in others; and transition (6 studies) from ambivalent to avoidant insecure attachment pattern and from passive to increasingly aggressive behavior and negative self-representation. Emotional knowledge, cognitive function, and language deteriorate without intervention. Poor sensitivity, hostility, criticism, or disinterest characterize maternal-child interactions. CONCLUSIONS AND RELEVANCE: Preschool children who have been neglected or emotionally abused exhibit a range of serious emotional and behavioral difficulties and adverse mother-child interactions that indicate that these children require prompt evaluation and interventions.

Estimating the probability of abusive head trauma: a pooled analysis.

CONTEXT AND OBJECTIVE: To determine which combinations of clinical features assist in distinguishing abusive head trauma (AHT) from nonabusive head trauma. METHODS: Individual patient data from 6 comparative studies of children younger than 3 years with intracranial injury were analyzed to determine the association between AHT and combinations of apnea; retinal hemorrhage; rib, skull, and long-bone fractures; seizures; and head and/or neck bruising. An aggregate analysis of data from these studies used multiple imputation of combined clinical features using a bespoke hotdeck imputation strategy, which accounted for uncertainty arising from missing information. RESULTS: Analyzing 1053 children (348 had AHT), excluding nonsignificant variables (gender, age, skull fractures), for a child with an intracranial injury and 1 or 2 of the 6 features, the positive predictive value (PPV) of AHT varies from 4% to 97% according to the different combinations. Although rarely recorded, apnea is significantly associated with AHT (odds ratio [OR]: 6.89 [confidence interval: 2.08-22.86]). When rib fracture or retinal hemorrhage was present with any 1 of the other features, the OR for AHT is >100 (PPV > 85%). Any combination of 3 or more of the 6 significant features yielded an OR of >100 (PPV for AHT > 85%). CONCLUSIONS: Probabilities of AHT can be estimated on the basis of different combinations of clinical features. The model could be further developed in a prospective large-scale study, with an expanded clinical data set, to contribute to a more refined tool to inform clinical decisions about the likelihood of AHT.
