    (ARRS, 2019-05) Wanner, Matthew R.; Marine, Megan B.; Hibbard, Roberta A.; Ouyang, Fangqian; Jennings, S. Gregory; Shea, Lindsey; Karmazyn, Boaz; Radiology and Imaging Sciences, School of Medicine
    OBJECTIVE. The purpose of this study is to perform a statewide quality improvement process to improve compliance with the American College of Radiology (ACR) guidelines in performing skeletal surveys for suspected child abuse. SUBJECTS AND METHODS. We prospectively identified all outside hospital skeletal surveys for suspected child abuse in children younger than 3 years referred to our tertiary children's hospital in 2016–2017. We included a 3-month baseline and 21-month intervention period. The quality improvement process was based on sending educational material to all ACR member radiologists in the state and making telephone calls to radiology technologist team leaders whenever the surveys were not compliant, followed by e-mails with guidance on performing skeletal surveys. We documented the views obtained and compared them with the ACR guidelines. The percentage of compliance with each individual view was assessed with the chi-square test. The total number of compliant views per survey was evaluated with ANOVA. RESULTS. Two hundred twenty-seven patients (105 female) with a mean age of 0.8 year (SD, 0.67 year; range, 0.01–3 years) were evaluated. These 227 surveys (baseline, n = 27; postintervention, n = 200) were performed at 69 different outside hospitals. Compliance significantly (p = 0.006) improved from 25.9% (7/27) during baseline to 54.0% (108/200) after intervention. There was a nonsignificant trend of improved compliance between the first (51.9%; 41/79) and last 7-month (62.3%; 33/53) periods of intervention. Among individual views, only rib oblique views showed significantly (p = 0.02) improved compliance after the intervention, from 51.9% (14/27) to 73.5% (147/200). CONCLUSION. The compliance rate with ACR guidelines for skeletal surveys in suspected child abuse at outside general hospitals significantly increased after implementation of a quality improvement process.

    Consultations in Child Abuse Pediatrics
    (Sage, 2020-07) Hicks, Ralph A.; Laskey, Antoinette L.; Harris, Tara L.; Hibbard, Roberta A.; Pediatrics, School of Medicine
    This study describes a hospital-based child abuse pediatrics consultation service. Medical records for all child abuse pediatrics consultations during 2006 to 2009 were reviewed. Descriptive statistics were used for data analysis. Of 2495 consultations, 13 were excluded due to insufficient information, 1682 were examinations for suspected sexual abuse, and 800 were examinations for nonsexual abuse concerns. Among the latter group of 800 patients, the most common reasons for consultation were fracture (33.5%), nonburn skin injury (16.8%), burn (15.4%), and intracranial injury (13.2%). Median patient age was 11 months (range = 3 days to 16 years). Case fatality rate was 3.9%. Final diagnosis was classified as definite/likely abuse in 40.0%, questionable/unknown in 24.5%, definite/likely accident in 23.6%, no injury in 4.6%, neglect in 4.0%, and a medical condition in 3.2%. Therefore, among consultations requested for suspected child maltreatment, a child abuse pediatrician concluded that abuse was definite or likely in less than half of patients.

    Ultrasound findings in classic metaphyseal lesions: emphasis on the metaphyseal bone collar and zone of provisional calcification
    (Springer, 2019) Marine, Megan B.; Hibbard, Roberta A.; Jennings, S. Gregory; Karmazyn, Boaz; Radiology and Imaging Sciences, School of Medicine
    Background The classic metaphyseal lesion (CML) is highly specific for non-accidental trauma in infants. While the radiographic findings are well documented, there is little literature on the ultrasound (US) appearance. Objective To evaluate US findings in CMLs identified on radiographs. Material and methods This institutional review board-approved, retrospective evaluation of targeted US of CMLs was performed in selected groups of children from 2014 to 2017. Only CMLs confidently identified on radiography by a consensus of two radiologists were included. US images were obtained with a linear transducer, including longitudinal images at lateral, anterior, medial and posterior aspects. Two pediatric radiologists evaluated the US appearance, specifically the metaphyseal bone collar for thickness, deformity and fracture, as well as the sonographic zone of provisional calcification for irregularity and appearance of multiple lines. Radiography was the reference standard. Results Twenty-two patients (13 female; mean age: 4.2 months) were identified, with 39 CMLs in the tibia (n=22), femur (n=11), humerus (n=3), radius (n=2) and fibula (n=1). Thirty-three of the 39 CMLs (85%) were identified on US, while 6 (15%) were not seen (false negatives). Thirty of the 39 (77%) had metaphyseal bone collar thickening, 29 (74%) had collar deformity and 12 (31%) had visible fracture of the collar. At the sonographic zone of provisional calcification, 16/39 (41%) had irregularity and 5 (13%) had multiple lines visible. Conclusion Identifying metaphyseal bone collar and zone of provisional calcification abnormalities is key to recognizing CMLs on US. While additional studies are necessary to evaluate the accuracy of US in the diagnosis of CMLs, our findings suggest US may have a potential role in either confirming or evaluating radiographically equivocal/occult CMLs.
