Intimate Partner Violence, Clinical Indications, and Other Family Risk Factors Associated With Pediatric Abusive Head Trauma.

Over half of fatal pediatric traumatic brain injuries are estimated to be the result of physical abuse, i.e., abusive head trauma (AHT). Although intimate partner violence (IPV) is a well-established risk for child maltreatment, little is known about IPV as an associated risk factor specifically for AHT. We performed a single-institution, retrospective review of all patients (0-17 years) diagnosed at a Level 1 pediatric trauma center with head trauma who had been referred to an in-hospital child protection team for suspicion of AHT between 2010 and 2016. Data on patient demographics, hospitalization, injury, family characteristics, sociobehavioral characteristics, physical examination, laboratory findings, imaging, discharge, and forensic determination of AHT were extracted from the institution's forensic registry. Descriptive statistics (mean, median), chi-square and Mann-Whitney U tests were used to compare patients with fatal head injuries to patients with nonfatal head injuries by clinical characteristics, family characteristics, and forensic determination. Multiple logistic regression was used to estimate adjusted odds ratios for the presence of IPV as an associated risk of AHT while controlling for other clinical and family factors. Of 804 patients with suspicion for AHT in the forensic registry, there were 240 patients with a forensic determination of AHT; 42 injuries were fatal. There were 101 families with a reported history of IPV; 64.4% of patients in families with reported IPV were <12 months of age. IPV was associated with a twofold increase in the risk of AHT (Exp(ß) = 2.3 [p = .02]). This study confirmed IPV was an associated risk factor for AHT in a single institution cohort of pediatric patients with both fatal and nonfatal injuries. Identifying IPV along with other family factors may improve detection and surveillance of AHT in medical settings and help reduce injury, disability, and death.

Evaluating abusive head trauma in children <5 years old: Risk factors and the importance of the social history.

BACKGROUND: Abusive head trauma (AHT) is the leading cause traumatic death in children ≤5 years of age. AHT remains seriously under-surveilled, increasing the risk of subsequent injury and death. This study assesses the clinical and social risks associated with fatal and non-fatal AHT. METHODS: A single-institution, retrospective review of suspected AHT patients ≤5 years of age between 2010 and 2016 using a prospective hospital forensic registry data yielded demographic, clinical, family, psycho-social and other follow-up information. Descriptive statistics were used to look for differences between patients with AHT and accidental head trauma. Logistic regression estimated the adjusted odds ratios (AOR) for AHT. A receiver operating characteristic (ROC) curve was created to calculate model sensitivity and specificity. RESULTS: Forensic evaluations of 783 children age ≤5 years with head trauma met the inclusion criteria; 25 were fatal with median[IQR] age 23[4.5-39.0] months. Of 758 non-fatal patients, age was 7[3.0-11.0] months; 59.5% male; 435 patients (57.4%) presented with a skull fracture, 403 (53.2%) with intracranial hemorrhage. Ultimately 242 (31.9%) were adjudicated AHT, 335(44.2%) were accidental, 181 (23.9%) were undetermined. Clinical factors increasing the risk of AHT included multiple fractures (Exp(ß) = 9.9[p = 0.001]), bruising (Expß = 5.7[p < 0.001]), subdural blood (Exp(ß) = 5.3[p = 0.001]), seizures (Exp(ß) = 4.9[p = 0.02]), lethargy/unresponsiveness (Exp(ß) = 2.24[p = 0.02]), loss of consciousness (Exp(ß) = 4.69[p = 0.001]), and unknown mechanism of injury (Exp(ß) = 3.9[p = 0.001]); skull fracture reduced the risk of AHT by half (Exp(ß) = 0.5[p = 0.011]). Social risks factors included prior police involvement (Exp(ß) = 5.9[p = 0.001]), substance abuse (Exp(ß) = 5.7[p = .001]), unknown number of adults in the home (Exp(ß) = 4.1[p = 0.001]) and intimate partner violence (Exp(ß) = 2.3[p = 0.02]). ROC area under the curve (AUC) = 0.90([95% CI = 0.86-0.93] p = .001) provides 73% sensitivity; 91% specificity. CONCLUSIONS: To improve surveillance of AHT, interviews should include and consider social factors including caregiver/household substance abuse, intimate partner violence, prior police involvement and household size. An unknown number of adults in home is associated with an increased risk of AHT. STUDY TYPE/LEVEL OF EVIDENCE: Prognostic, Level III.

Inflicted versus unintentional injury: towards improved detection and surveillance of supervisory neglect.

BACKGROUND: Many children evaluated for child abuse have non-inflicted injuries due to supervisory neglect. Despite its prevalence, supervisory neglect has received minimal attention. METHODS: We performed a retrospective review of patients maintained in a hospital forensic registry. Text analytics software was used to classify types of supervisory neglect from reported mechanism of injury (MOI). Logistic regression was used to assess risks associated with supervisory neglect. RESULTS: For 1185 eligible patients, 553 were classified as having unintentional injuries. Text analysis identified four types of supervisory neglect for falls (N = 376): interrupted supervision (53.4%); failure to adapt the home (26.7%); safety equipment non-compliance (12.8%); inadequate substitute care (7.0%); a fifth category was identified for non-falls (N = 54): rough handling (32.0%). Supervisory neglect was associated with MOI consistent with the injury (AOR = 15.5[p < 0.001]), no loss of consciousness (AOR = 6.8(p < 0.001]), no bruising away from the injury site (AOR = 3.7[p < 0.001]), and direct hospital presentation (AOR = 1.8[p < 0.05]). Of the 553 with unintentional injury, 62% had isolated head injuries; 20%, however, had evidence of prior head trauma. CONCLUSIONS: Interrupted supervision was the most common form of supervisory neglect. Twenty percent of forensics patients with head injury found to have non-inflicted injuries had evidence of prior head injury. Supervisory neglect suggests a high-risk population. LEVEL OF EVIDENCE: Level II, Prognosis.
