Preliminary Development of a Performance Assessment Tool for Documentation of History Taking in Child Physical Abuse.

OBJECTIVES: This study aimed to develop a performance assessment tool for the history-taking components of the medical evaluation of physical abuse in young children by (1) determining the consensus-based injury history and social components for documentation, (2) identifying preliminary performance standards, (3) assessing current level-specific performance using the created tools, and (4) evaluating reliability and validity of the created tools. METHODS: The Physical Abuse Assessment Tool (PHAAT) was developed in 2 steps: (1) a modified Delphi survey was used to identify the injury history and social components for documentation in a medical evaluation for physical abuse, and (2) level-specific ("novice," "competent," "expert") practice standards (minimum passing scores) were created using the identified components via the Angoff method. To evaluate validity, reliability, and level-specific performance of the PHAAT, a chart review of 50 consecutive cases from each of the 3 levels was performed. RESULTS: Seventy-one child abuse pediatricians and 39 social workers participated in the modified Delphi survey, and 67 child abuse pediatricians and 27 social workers participated in the Angoff method. The resulting PHAAT included 2 checklists for use based on presence or absence of a history of an injurious event. One-way analysis of variance shows significant differences in performance based on team level (P < 0.001), indicating construct validity. Intrarater and interrater reliability evaluations showed strong (rs = 0.64-0.92) and moderate to strong (intraclass correlation coefficient = 0.81-0.98) correlations, respectively. CONCLUSIONS: Initial evaluation suggests the PHAAT may be a reliable and valid practice assessment tool for the medical evaluation of physical abuse.

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.

A witnessed case of a classic metaphyseal fracture caused during IV line placement in a child: Insight into mechanism of injury.

Recent publications argue that classic metaphyseal fractures are caused by rickets as opposed to trauma. Previous case reports of accidental traumatic classic metaphyseal fractures have been discounted due to lack of identification of the fracture at the time of the traumatic event, and lack of an evaluation for boney metabolic disorders. We report a case of a 20 day old male with a diagnosis of congenital vertical talus who sustained a classic metaphyseal fracture of the distal tibia during manipulation in preparation for intravenous line placement. The mechanics of the event causing the classic metaphyseal fracture were witnessed and accompanied by an audible "pop". Prior x-rays of the tibia demonstrate normal osseous morphology, and an evaluation for boney metabolic disorders was normal. This case identifies a traumatic classic metaphyseal fracture and provides insight into the types of forces necessary to cause such a fracture.
