The pediatric subspecialty of Child Abuse Pediatrics (CAP) was certified by the American Board of Medical Subspecialties in 2006. Relative to its impact on pediatric health, CAP-focused research has been relatively under-funded. Multi-center networks related to CAP-focused research have made important advances, but have been limited in scope and duration. CAPNET is multi-center network whose mission is to support CAP-focused research.To describe the rationale, development, and scope of the CAPNET research network infrastructure, the CAPNET data registry and associated data resources.Based on existing priorities for CAP-focused research, we used consensus building and iterative testing to establish inclusion criteria, common data elements, data quality assurance, and data sharing processes for children with concerns of physical abuse.We describe the rationale, methods and intended scope for the development of the CAPNET research network and data registry. CAPNET is currently abstracting data for children10 years (120 months) old who undergo sub-specialty evaluation for physical abuse at 10 US pediatric centers (approximately 4000 evaluations/year total) using an online data capture form. Data domains include: demographics; visit timing and providers, medical/social history, presentation, examination findings, laboratory and radiographic testing, diagnoses, outcomes, and data for contact children. We describe the methods and criteria for collecting and validating data which are broadly available to CAP investigators.CAPNET represents a new data resource for the CAP research community and will increase the quantity and quality of CAP-focused research.

Background There is significant variability in Child Protective Services (CPS) utilization of medical-forensic experts. In 2016, Missouri legislation (HB 1877) mandated that CPS investigators submit screening forms to a Child Abuse Pediatrician (CAP) to review children Objective To measure compliance with HB 1877, hypothesizing that urban counties would have better compliance than rural counties. Participants and setting This retrospective study included evaluation of screening forms completed by Missouri CPS and submitted to Missouri CAPs during February, July and September of 2017. Methods Compliance was measured in three ways. Compliance Measure 1 (CM1) was the number of screening forms versus the number of eligible CPS investigations. Compliance Measure 2 (CM2) was the average number of days from an abuse report until form submission, and Compliance Measure 3 (CM3) was the percentage of forms with complete information. Urban and rural counties were classified by 2010 census data. t-Tests were used to compare compliance measures between urban and rural counties. Results Overall compliance with CM1 was 69% with 1496 screening forms submitted and 2170 child maltreatment investigations for children less than 4 years of age. For CM2, mean days from abuse report to form submission was 30 days. For CM3, 60.5% of statewide forms were complete. There was no significant difference between rural and urban county compliance. Conclusions Limited compliance with HB 1877 demonstrates the necessity of continued monitoring and improvement for optimal efficacy of legal mandates.

Background There exists a presumption that school closures lead to a diminished capacity to detect child maltreatment, but empiric evidence is lacking. Objective To determine if child maltreatment reporting and substantiation differ between periods when schools are routinely closed compared to in session. Participants and setting Child maltreatment reporting and substantiation among all U.S. States and the District of Columbia from January 1, 2010 through December 31, 2017. Methods Two-week intervals during periods of routine school closure (early January, June through mid-August, late November, and late December) were compared to all other 2-week intervals. Negative binomial generalized estimating equations compared rates of reporting and substantiation, resulting in incidence rate ratios (IRR) with 95% confidence intervals (CI). Results Compared to when school was in session, reporting was 16.0% (IRR 0.84 [95% CI: 0.83, 0.85]) lower during school closures and substantiations were 12.3% (IRR 0.88 [95% CI: 0.86, 0.89]) lower. The largest reductions in reporting were observed among education personnel (−42.1%; IRR 0.58 [95% CI: 0.54, 0.62]), children aged 5–17 years (−18.6%; IRR 0.81 [95% CI: 0.80, 0.83), and for physical abuse (−19.6%; IRR 0.80 [95% CI: 0.79, 0.82]). Reductions during closure periods were not matched by increases during two-week intervals immediately following closure periods. Conclusions Results suggest that the detection of child maltreatment may be diminished during periods of routine school closure. Findings may inform prevention planning and risk-benefit analyses for future school closures. Further study should disentangle the issue of decreased detection versus decreased prevalence of maltreatment during school closures.

The characteristic findings of abusive head trauma (AHT) include retinal hemorrhages (RH). RH have many etiologies in childhood, which should be considered in the differential diagnosis of possible child abuse. The relationship between RH and thrombophilia in children is not well established.In this literature review, we sought to assess whether retinal findings in pediatric patients with thrombophilia could mimic those of AHT.A literature search was performed to identify all cases of thrombophilia in children less than 18 years old with ocular manifestations. Disorders of thrombophilia including protein C and S deficiency, factor V Leiden (FVL), prothrombin variant, MTHFR mutation, hyperhomocysteinemia, elevated factor VIII, and elevated lipoprotein (a) were considered. All cases of pediatric thrombophilia with retinal examination or intraocular bleeding were included. If provided, descriptions of the RH were reviewed.Our initial search yielded 514 results. Forty-three articles met our inclusion criteria. We identified 3 children with RH within the AHT usual age range (5 years old), ages 5 weeks and 7 weeks old, in the setting of thrombophilia. One child had ocular findings that could potentially mimic abuse. No other indicators of abuse were present in this case.Based on previous reports, thrombophilia alone has not been shown to clearly mimic abusive head trauma. In reported cases of thrombophilia with RH, the clinical picture and ophthalmic findings are usually distinct from abuse.

Cerebral sinovenous thrombosis (CSVT) is a postulated cause of subdural hemorrhage (SDH) that is hypothesized to mimic abusive head trauma (AHT). Minimal data exists directly investigating this relationship.To evaluate the frequency of SDH in children with CSVT, identify factors associated with CSVT and SDH, and to assess if any association supports the hypothesis that CSVT causes SDH.The International Pediatric Stroke Study (IPSS) prospectively collects data on subjects birth to 19 years of age with intracranial thrombosis.IPSS subjects with CSVT and SDH were compared to those with CSVT and no SDH. For subjects with CSVT and SDH, neuroimaging reports further characterized the findings. In any case with no known risk factors for SDH, neuroimaging studies were reviewed by a pediatric neuroradiologist.Of 216 subjects with CSVT, 20 (9.3%) had SDH. Those with SDH (median age 0.3 years) were younger than those without SDH (median age 4.2 years), p 0.001. Subjects with CSVT and SDH more frequently had anoxia (OR = 10.8; 95% CI: 1.4, 81.1), head/neck injury (OR = 4.0; 95% CI: 1.3, 12.6), or abnormal consciousness (OR = 3.0; 95% CI: 1.2, 7.6). Of 20 subjects with CSVT and SDH, 19 had known risk factors for SDH. The remaining subject had a chronic SDH identified concomitantly to a newly symptomatic CSVT with accompanying venous infarctions.SDH in the setting of CSVT is typically identified in children with independent risk factors for SDH. This study does not support the hypothesis that CSVT causes SDH.

Still photo imaging is often used in medical evaluations of child sexual abuse (CSA) but video imaging may be superior. We aimed to compare still images to videos with respect to diagnostic agreement regarding hymenal deep notches and transections in post-pubertal females. Additionally, we evaluated the role of experience and expertise on agreement. We hypothesized that videos would result in improved diagnostic agreement of multiple evaluators as compared to still photos. This was a prospective quasi-experimental study using imaging modality as the quasi-independent variable. The dependent variable was diagnostic agreement of participants regarding presence/absence of findings indicating penetrative trauma on non-acute post-pubertal genital exams. Participants were medical personnel who regularly perform CSA exams. Diagnostic agreement was evaluated utilizing a retrospective selection of videos and still photos obtained directly from the videos. Videos and still photos were embedded into an on-line survey as sixteen cases. One-hundred sixteen participants completed the study. Participant diagnosis was more likely to agree with study center diagnosis when using video (p

Little is known regarding sources of diagnostic error at the provider level in cases of possible child physical abuse. This study examines medical diagnosis as part of medical management and not as part of legal investigation. Simulation offers the opportunity to evaluate diagnostic accuracy and identify error sources. We aimed to identify sources of medical diagnostic error in cases of possible abuse by assessing diagnostic accuracy, identifying gaps in evaluation, and characterizing information used by medical providers to reach their diagnoses. Eight femur fracture simulation cases, half of which were abuse and half accident, were created. Providers from a tertiary pediatric emergency department participated in a simulation exercise involving 1 of the 8 cases. Performance was evaluated using structured scoring tools and debriefing, and qualitative analysis characterized participants' rationales for their diagnoses. Overall, 39% of the 43 participants made an incorrect diagnosis regarding abuse. An incorrect diagnosis was over 8 times more likely to occur in accident than in abuse cases (OR=8.8; 95% CI 2 to 39). Only 58% of participants correctly identified the fracture morphology, 60% correctly identified the mechanics necessary to generate the morphology, and 30% of ordered all appropriate tests for occult injury. In misdiagnoses, participants frequently falsely believed the injury did not match the proposed mechanism and the history provided by the caregiver had changed. Education programs targeting the identified error sources may result in fewer diagnostic errors and improve outcomes. The findings also support the need for referral to child abuse experts in many cases.

Investigation for bleeding disorders in the context of suspected non-accidental injury (NAI) is inconsistent. We reviewed the hematologic evaluation of children who presented with symptoms of bleeding and/or bruising suspicious for NAI to determine the frequency of hematologic tests, abnormal hematologic laboratory results, and hematologic diagnoses. A retrospective cohort study design was employed at two freestanding academic children's hospitals. ICD-9 codes for NAI were used to identify 427 evaluable patients. Medical records were queried for the details of clinical and laboratory evaluations at the initial presentation concerning for NAI. The median age for the population was 326 days (range 1 day–14 years), 58% were male. Primary bleeding symptoms included intracranial hemorrhage (31.8%) and bruising (68.2%). Hematologic laboratory tests performed included complete blood cell count in 62.3%, prothrombin time (PT) in 55.0%, and activated partial thromboplastin time (aPTT) in 53.6%; fibrinogen in 27.6%; factor activity in 17.1%; von Willebrand disease evaluation in 14.5%; and platelet function analyzer in 11.7%. Prolonged laboratory values were seen in 22.5% of PT and 17.4% of aPTT assays; 66.0% of abnormal PTs and 87.5% of abnormal aPTTs were repeated. In our cohort, 0.7% (3 of 427) of the population was diagnosed with a condition predisposing to bleeding. In children with bleeding symptoms concerning for NAI, hemostatic evaluation is inconsistent. Abnormal tests are not routinely repeated, and investigation for the most common bleeding disorder, von Willebrand disease, is rare. Further research into the extent and appropriate timing of the evaluation is warranted.

OBJECTIVE: In a rural area of the US state of Texas, in April 2008, the Texas Department of Family and Protective Services (DFPS) responded to evidence of widespread child abuse in an isolated religious compound by removing 463 individuals into state custody. This mass child protection intervention is the largest such action that has ever occurred in the United States. The objective of this paper is to characterize the burdens placed on the area's community resources, healthcare providers, and legal system, the limitations encountered by the forensic and public health professionals, and how these might be minimized in future large-scale child protection interventions. METHODS: Drawing on publicly available information, this article describes the child abuse investigation, legal outcomes, experiences of pediatric healthcare providers directly affected by the mass removal, and the roles of regional child abuse pediatric specialists. RESULTS: Because the compound's residents refused to cooperate with the investigation and the population of the compound was eight times higher than expected, law enforcement and child protection resources were insufficient to conduct standard child abuse investigations. Local medical and public health resources were also quickly overwhelmed. Consulting child abuse pediatricians were asked to recommend laboratory and radiologic studies that could assist in identifying signs of child abuse, but the lack of cooperation from patients and parents, inadequate medical histories, and limited physical examinations precluded full implementation of the recommendations. CONCLUSIONS: Although most children in danger of abuse were removed from the high-risk environment for several months and some suspected abusers were found guilty in criminal trials, the overall success of the child protection intervention was reduced by the limitations imposed by insufficient resources and lack of cooperation from the compound's residents. PRACTICE IMPLICATIONS: Recommendations for community and child abuse pediatricians who may become involved in future large child-protection interventions are presented. Language: en

OBJECTIVES: To characterize the changes regarding the diagnosis of physical abuse provided to Child Protective Services (CPS) when CPS asks a Child Abuse Pediatrics (CAP) specialty group for a second opinion and works in concert with that CAP group. METHODS: Subjects were reported to CPS for suspected physical abuse and were first evaluated by a physician without specialized training in Child Abuse Pediatrics (non-CAP physician). Subjects were then referred to the area's only Child Abuse Pediatrics (CAP physician) group, located in a large metropolitan pediatrics center in the United States, for further evaluation. The diagnoses regarding abuse provided by CAP physicians working in concert with CPS were compared to those provided to CPS by other physicians. RESULTS: Two hundred consecutive patients were included in the study. In 85 (42.5%) cases, non-CAP physicians did not provide a diagnosis regarding abuse, despite initiating the abuse report to CPS or being asked by CPS to evaluate the child for physical abuse. Of the remaining 115 cases, the diagnosis regarding abuse differed between non-CAP physicians and CAP physicians working in concert with CPS in 49 cases (42.6%; kappa=.14; 95% CI, -.02, .29). In 40 of the 49 cases (81.6%), CAP assessments indicated less concern for abuse when compared to non-CAP assessments. Differences in diagnosis were three times more likely in children from a nonurban location (OR 3.24; 95% CI, 1.01, 11.36). CONCLUSIONS: In many cases of possible child physical abuse, non-CAP providers do not provide CPS with a diagnosis regarding abuse despite initiating the abuse investigation or being consulted by CPS for an abuse evaluation. CPS consultation with a CAP specialty group as a second opinion, along with continued information exchange and team collaboration, frequently results in a different diagnosis regarding abuse. Non-CAP providers may not have time, resources, or expertise to provide CPS with appropriate abuse evaluations in all cases. PRACTICE IMPLICATIONS: Though non-CAP providers may appropriately evaluate many cases of physical abuse, the diagnosis regarding abuse provided to CPS may be changed in some cases when CAP physicians are consulted and actively collaborate with CPS investigators. Availability of Child Abuse Pediatrics subspecialty services to investigators is warranted. Language: en
