Abstract/Description

OBJECTIVE: Physicians are occasionally asked to evaluate children who are reported to have been victims of witnessed abuse, but who have no injuries noted on examination. The rate of injury in these patients is presently unknown. This is important because abuse allegations are brought for both altruistic and other reasons. This study compares the use of skeletal survey and neuroimaging in well-appearing and clearly injured children reported to be victims of witnessed child abuse. METHODS: Retrospectively planned secondary analysis of the Examination of Siblings to Recognize Abuse cohort of children referred to a child abuse pediatrician with concerns for physical abuse. Children were selected who presented to a medical provider with a history of witnessed child abuse including shaking. Rates of radiographically evident injuries are noted among children with and without injuries noted on physical examination. RESULTS: Among 2890 children evaluated by a child abuse pediatrician, 90 children (3.1%) presented with a history of witnessed abuse. Among these, 51 children (57%) had injuries noted on physical examination; 9 (29%) of 31 skeletal surveys and 9 (35%) of 26 neuroimaging studies revealed injuries. Of 39 children (43%) with witnessed abuse and normal examination, 3 (10%) of 30 skeletal surveys and 2 (8%) of 25 neuroimaging studies revealed an injury. CONCLUSION: A significant minority of children evaluated for allegations of witnessed abuse will have occult injuries identified radiographically. Absence of injury on examination should not deter physicians from obtaining otherwise indicated skeletal surveys and neuroimaging in children reported to have experienced witnessed abuse.

Abstract/Description

OBJECTIVE: To determine the frequency of occult trauma in children with oral injury evaluated for physical abuse. DESIGN: This was a retrospectively planned secondary analysis of a prospective, observational study. Setting Emergency departments supported by 20 US child abuse teams in the ExSTRA network. Patients Children <120 months old evaluated for physical abuse. Interventions Analysis of index children with oral injury on initial examination. MAIN OUTCOME MEASURES: Rates of physician-recognised oral injury, as well as frequency and results of occult injury testing. Perceived abuse likelihood was described on a 7-point scale (7=definite abuse). RESULTS: Among 2890 child abuse consultations, 3.3% (n=96) of children had oral injury. Forty-two per cent were 0–12 months old, 39% 1–3 years old and 18% >3 years old. Oral injury was the primary reason for evaluation for 32 (33%). Forty-three per cent (42/96) had frenum injuries. Skeletal surveys were obtained for 84% and 25% of these identified occult fractures. Seventy-five per cent had neuroimaging; 38% identified injuries. Forty-one per cent of children with oral injuries had retinal examinations; 24% of exams showed retinal haemorrhages. More occult injuries were found in children with oral injuries than other ExSTRA subjects. A high level of concern for abusive injury was present in 67% of children with oral injury versus 33% without. CONCLUSIONS: Children with oral injury are at high risk for additional occult abusive injuries. Infants and mobile preschoolers are at risk. Young children with unexplained oral injury should be evaluated for abuse.

Abstract/Description

Skeletal survey is frequently used to identify occult fractures in young children with concern for physical abuse. Because skeletal survey is relatively insensitive for some abusive fractures, a follow-up skeletal survey (FUSS) may be undertaken at least 10-14 days after the initial skeletal survey to improve sensitivity for healing fractures. This was a prospectively planned secondary analysis of a prospective, observational study of 2,890 children who underwent subspecialty evaluation for suspected child physical abuse at 1 of 19 centers. Our objective was to determine variability between sites in rates of FUSS recommendation, completion and fracture identification among the 2,049 participants who had an initial SS. Among children with an initial skeletal survey, the rate of FUSS recommendation for sites ranged from 20% to 97%; the rate of FUSS completion ranged from 10% to 100%. Among sites completing at least 10 FUSS, rates of new fracture identification ranged from 8% to 28%. Among completed FUSS, new fractures were more likely to be identified in younger children, children with higher initial level of concern for abuse, and those with a fracture or cutaneous injury identified in the initial evaluation. The current variability in FUSS utilization is not explained by variability in occult fracture prevalence. Specific guidelines for FUSS utilization are needed.

Abstract/Description

Intentional burns represent a serious form of physical abuse that must be identified to protect children from further harm. This study is a retrospectively planned secondary analysis of the Examining Siblings To Recognize Abuse (ExSTRA) network data. Our objective was to describe the characteristics of burns injuries in children referred to Child Abuse Pediatricians (CAPs) in relation to the perceived likelihood of abuse. We furthermore compare the extent of diagnostic investigations undertaken in children referred to CAPs for burn injuries with those referred for other reasons. Within this dataset, 7% (215/2890) of children had burns. Children with burns were older than children with other injuries (median age 20 months vs. 10 months). Physical abuse was perceived as likely in 40.9% (88) and unlikely in 59.1% (127). Scalds accounted for 52.6% (113) and contact burns for 27.6% (60). Several characteristics of the history and burn injury were associated with a significantly higher perceived likelihood of abuse, including children with reported inflicted injury, absent or inadequate explanation, hot water as agent, immersion scald, a bilateral/symmetric burn pattern, total body surface area ≥10%, full thickness burns, and co-existent injuries. The rates of diagnostic testing were significantly lower in children with burns than other injuries, yet the yield of skeletal survey and hepatic transaminases testing were comparable between the two groups. This would imply that children referred to CAPs for burns warrant the same level of comprehensive investigations as those referred for other reasons.

Abstract/Description

OBJECTIVE: To determine rates of screening in contacts of children evaluated for physical abuse, and the relationship of clinical characteristics to screening recommendation and completion and injury identification. STUDY DESIGN: This is a planned secondary analysis of a prospective study of 1918 contacts of 1196 children referred for subspecialty abuse consultation in 20 US centers. We used multivariable logistic models to determine the relationship of index child characteristics, contact child characteristics, and shared characteristics to screening and injury identification. RESULTS: We identified injuries or disclosures of abuse in 180 (9.4%) contacts. Recommended screening was omitted in >20% of subjects for each screening modality. At least 1 screening test was more likely to be completed in contacts of index children of non-White race or Hispanic ethnicity (OR 1.45, 95% CI 1.13-1.87), with abuse-specific injuries (OR 2.15, 95% CI 1.63-2.83), with a confession (OR 2.18, 95% CI 1.17-4.07), when the history changed (OR 1.65, 95% CI 1.05-2.61), when an occult injury was found by imaging in the index child (OR 1.84, 95% CI 1.39-2.43), and when families lacked private insurance (OR 1.63, 95% CI 1.15-2.31). CONCLUSION: Completion of screening recommended for contacts of potentially abused children is relatively poor, despite high risk of injury. Several clinical and demographic factors were associated with increased contact screening.

Abstract/Description

Incorrect diagnoses during child abuse evaluations are serious. Because skin lesions are common in abuse, it is important to consider cutaneous mimics of physical abuse. The current study prospectively identified cutaneous mimics in a cohort of children evaluated for possible physical abuse. This is a secondary analysis of data from the Examining Siblings To Recognize Abuse research network's prospective, observational, cross-sectional study involving 20 U.S. child abuse teams. Subjects were younger than 10 years old and were evaluated by child abuse physicians (CAPs) for concerns of physical abuse. CAPs prospectively documented whether mimics were identified during their physical abuse evaluations. Details of each patient with cutaneous mimics were evaluated to determine the types of mimics, which part of the evaluations identified mimics, and the perceived abuse likelihood. Of 2,890 children evaluated for physical abuse, 137 had at least one mimic identified and 69 had some cutaneous mimic components. Although 985 of 2,753 (39%) subjects without mimics had high levels of abuse concern, only 9 of 137 (6%) children with mimics had high levels of abuse concern (p < 0.001). Of 69 children with cutaneous mimics, 56 (81%) were diagnosed by history and physical examination. Cutaneous abuse mimics were identified in 2.4% of children evaluated for physical abuse. Although it was eventually determined that there was little or no concern for abuse in 84% of children with cutaneous mimics, a small number were physically abused. CAP evaluation may be valuable in recognizing children with cutaneous mimics who also were abused.

Abstract/Description

Physically abused children may be repeatedly reported to child protection services and undergo multiple medical evaluations. Less is known about recurrent evaluations by hospital-based child abuse teams for possible abuse. The objectives of this study were to determine the frequency of repeated consultations by child abuse teams and to describe this cohort in terms of injury pattern, perceived likelihood of abuse, disposition plan, and factors related to repeat consultation. This was a prospectively planned, secondary analysis of data from the ExSTRA research network. Subjects included children younger than 10 years of age who were referred to child abuse subspecialty teams at one of 20 U.S. academic centers. Repeat consultations occurred in 101 (3.5%; 95% CI 2.9-4.2%) of 2890 subjects. The incidence of death was 4% (95% CI 1-9%) in subjects with repeated consults and 3% (95% CI 2-3%) in subjects with single consults. Perceived likelihood of abuse from initial to repeat visit remained low in 33% of subjects, remained high in 24.2% of subjects, went from low to high in 16.5%, and high to low in 26.4% of subjects. Themes identified among the subset of patients suspected of repeated abuse include return to the same environment, failure to comply with a safety plan, and abuse in foster care. Repeated consultation by child abuse specialists occurs for a minority of children. This group of children may be at higher risk of subsequent abuse and may represent an opportunity for quality improvement.

Abstract/Description

OBJECTIVE: To determine the prevalence of additional injuries or bleeding disorders in a large population of young infants evaluated for abuse because of apparently isolated bruising. STUDY DESIGN: This was a prospectively planned secondary analysis of an observational study of children<10 years (120 months) of age evaluated for possible physical abuse by 20 US child abuse teams. This analysis included infants<6 months of age with apparently isolated bruising who underwent diagnostic testing for additional injuries or bleeding disorders. RESULTS: Among 2890 children, 33.9% (980/2890) were <6 months old, and 25.9% (254/980) of these had bruises identified. Within this group, 57.5% (146/254) had apparently isolated bruises at presentation. Skeletal surveys identified new injury in 23.3% (34/146), neuroimaging identified new injury in 27.4% (40/146), and abdominal injury was identified in 2.7% (4/146). Overall, 50% (73/146) had at least one additional serious injury. Although testing for bleeding disorders was performed in 70.5% (103/146), no bleeding disorders were identified. Ultimately, 50% (73/146) had a high perceived likelihood of abuse. CONCLUSIONS: Infants younger than 6 months of age with bruising prompting subspecialty consultation for abuse have a high risk of additional serious injuries. Routine medical evaluation for young infants with bruises and concern for physical abuse should include physical examination, skeletal survey, neuroimaging, and abdominal injury screening.

Abstract/Description

OBJECTIVE: To determine rates of skeletal survey completion and injury identification as a function of age among children who underwent subspecialty evaluation for concerns of physical abuse. STUDY DESIGN:
This was a retrospective secondary analysis of an observational study of 2609 children <60 months of age who underwent evaluation for possible physical abuse. We measured rates of skeletal survey completion and fracture identification for children separated by age into 6-month cohorts. RESULTS: Among 2609 subjects, 2036 (78%) had skeletal survey and 458 (18%) had at least one new fracture identified. For all age groups up to 36 months, skeletal survey was obtained in >50% of subjects, but rates decreased to less than 35% for subjects >36 months. New fracture identification rates for skeletal survey were similar between children 24-36 months of age (10.3%, 95% CI 7.2-14.2) and children 12-24 months of age (12.0%, 95% CI 9.2-15.3). CONCLUSIONS: Skeletal surveys identify new fractures in an important fraction of children referred for subspecialty consultation with concerns of physical abuse. These data support guidelines that consider skeletal survey mandatory for all such children <24 months of age and support a low threshold to obtain skeletal survey in children as old as 36 months.

Abstract/Description

OBJECTIVE: To determine the frequency of non-cutaneous mimics identified in a large, multicentre cohort of children evaluated for physical abuse. METHODS: Prospectively planned, secondary analysis of 2890 physical abuse consultations from the ExSTRA research network. Data for each enrolled subject were entered at the child abuse physician's diagnostic disposition. Physicians prospectively documented whether or not a 'mimic' was identified and the perceived likelihood of abuse. Mimics were divided into 3 categories: (1) strictly cutaneous mimics, (2) strictly non-cutaneous mimics and (3) cutaneous and non-cutaneous mimics. Perceived likelihood of abuse was described for each child on a 7-point scale (7=definite abuse). RESULTS: Among 2890 children who were evaluated for physical abuse, 137 (4.7%) had mimics identified; 81 mimics (59.1% of mimics and 2.8% of the whole cohort) included non-cutaneous components. Six subjects (7.4%) were assigned a high level of abuse concern and 17 (20.1%) an intermediate level despite the identification of a mimic. Among the identified mimics, 28% were classified as metabolic bone disease, 20% haematologic/vascular, 16% infectious, 10% skeletal dysplasia, 9% neurologic, 5% oncologic, 2% gastrointestinal and 10% other. Osteomalacia/osteoporosis was the most common non-cutaneous mimic followed by vitamin D deficiency. CONCLUSIONS: A wide variety of mimics exist affecting most disease categories. Paediatric care providers need to be familiar with these conditions to avoid pitfalls in the diagnosis of physical abuse. Identification of a mimic does not exclude concurrent abuse.

Abstract/Description

OBJECTIVE: Routine testing of hepatic transaminases, amylase, and lipase has been recommended for all children evaluated for physical abuse, but rates of screening are widely variable, even among abuse specialists, and data for amylase and lipase testing are lacking. A previous study of screening in centers that endorsed routine transaminase screening suggested that using a transaminase threshold of 80 IU/L could improve injury detection. Our objectives were to prospectively validate the test characteristics of the 80-IU/L threshold and to determine the utility of amylase and lipase to detect occult abdominal injury. METHODS: This was a retrospective secondary analysis of the Examining Siblings To Recognize Abuse research network, a multicenter study in children younger than 10 years old who underwent subspecialty evaluation for physical abuse. We determined rates of identified abdominal injuries and results of transaminase, amylase, and lipase testing. Screening studies were compared by using basic test characteristics (sensitivity, specificity) and the area under the receiver operating characteristic curve. RESULTS: Abdominal injuries were identified in 82 of 2890 subjects (2.8%; 95% confidence interval: 2.3%-3.5%). Hepatic transaminases were obtained in 1538 (53%) subjects. Hepatic transaminases had an area under the receiver operating characteristic curve of 0.87. A threshold of 80 IU/L yielded sensitivity of 83.8% and specificity of 83.1%. The areas under the curve for amylase and lipase were 0.67 and 0.72, respectively. CONCLUSIONS: Children evaluated for physical abuse with transaminase levels >80 IU/L should undergo definitive testing for abdominal injury.

Abstract/Description

OBJECTIVE: Recently, it has been suggested that views of the hands, feet, spine, and pelvis should be omitted from routine skeletal surveys (SSs) because these fractures are rarely identified by SS. Our objective was to describe the prevalence of fractures to the hands, feet, spine, or pelvis among SSs obtained for children in a large, multicenter population who underwent consultation for physical abuse. METHODS: This was a retrospective secondary analysis of data from the Examining Siblings To Recognize Abuse research network, a consortium of 20 U.S. child abuse teams who collected data for all children younger than 10 years who underwent consultation for concerns of physical abuse. This secondary analysis included data only from index children and excluded data from siblings and contacts. Consulting child abuse physicians reported the number of fractures identified and those that were detected by SS. RESULTS: Among 2049 initial SSs, 471 (23.0%) showed at least 1 previously unknown fracture including 49 (10.4%) that showed a fracture to the hands, feet, spine, or pelvis. In 10 cases, the SS identified at least 1 fracture of the hands, feet, spine, or pelvis when no other fractures were identified. CONCLUSIONS: A significant number of occult, abusive fractures would have been missed if SSs had omitted or deferred views of the hands, feet, spine, and pelvis. Given the risks associated with missed abuse, these views should be routinely included in the radiographic SS.

Abstract/Description

OBJECTIVE: Follow-up skeletal surveys (FUSS) are performed frequently in cases of possible physical abuse based on the evidence from small retrospective cohorts. Our objective was to determine the proportion of FUSS that identified new information in a large, multicenter population of children with concerns of physical abuse. METHODS: This was a prospective secondary analysis of an observational study of all children <10 years of age (120 months) who underwent evaluation for possible physical abuse by 20 US child abuse teams. This analysis included all children in whom FUSS was recommended and measured rates of FUSS completion, results of FUSS, and the change in perceived likelihood of abuse before and after FUSS. RESULTS: Among 2890 children enrolled in the Examining Siblings To Recognize Abuse research network, 2049 underwent skeletal survey and 796 (38.8%) had FUSS. A total of 174 (21.5%) subjects had new information identified by FUSS, including 124 (15.6%) with at least 1 new fracture and 55 (6.9%) with reassuring findings compared with the initial skeletal survey. Among cases with new fractures, the estimated likelihood of abuse increased in 41 (33%) cases, and 51 cases (41%) remained at the maximum likelihood of abuse. CONCLUSIONS: FUSS identified new information and affected the perceived likelihood of abuse in a substantial fraction of cases in which it was completed. These data support existing guidelines and, in addition, suggest that FUSS should be considered in cases with lower initial levels of concern for abuse.

Abstract/Description

To the Editor: We congratulate the Pediatric Emergency Care Applied Research Network (PECARN) investigators for another important study, which, when validated, could be a powerful tool to decrease unnecessary radiation exposure in children. However, we caution that there is potential for harm if this rule, even when validated, is applied to children with concern for physical abuse.

Abstract/Description

OBJECTIVE: To determine the rate of retinal hemorrhages in children evaluated for physical abuse without traumatic brain injury (TBI) by diagnostic imaging. STUDY DESIGN: This study was a prospectively planned, secondary analysis of the Examining Siblings to Recognize Abuse (ExSTRA) research network, and included only index children who presented with concerns for abuse. Subjects were eligible for the parent study if they were less than 10 years old and evaluated by a Child Abuse Physician for concerns of physical abuse. Child Abuse Physicians recorded results of all screening testing and determination of the likelihood of abuse in each case. For this analysis, we examined the results of dedicated retinal examinations for children with neuroimaging that showed no TBI. Isolated skull fractures were not considered to be TBI. RESULTS: The original ExSTRA sample included 2890 index children evaluated for physical abuse. Of this group, 1692 underwent neuroimaging and 1122 had no TBI. Of these 1122 children, 352 had a dedicated retinal examination. Retinal hemorrhages were identified in 2 (0.6%) children. In both cases, there were few (defined as 3-10) hemorrhages isolated to the posterior poles; neither was diagnosed with physical abuse. The presence of facial bruising, altered mental status, or complex skull fractures was neither sensitive nor specific for retinal hemorrhage identification. CONCLUSIONS: Forensically significant retinal hemorrhages are unlikely to be found in children evaluated for physical abuse without TBI on neuroimaging, and such children may not require routine dedicated retinal examination.

Abstract/Description

BACKGROUND: There is currently no consensus about which screening studies should be undertaken to identify abusive injuries in infants with apparently isolated skull fractures. Our objective was to determine rates of screening, rates of injury identification, and rates of reporting to child protective services among infants who underwent subspecialty evaluation for abuse after presenting with an apparently isolated skull fracture. METHODS: This was a retrospectively planned, secondary analysis of index children enrolled in a large network of children with concerns for physical abuse. For this analysis, we included infants (<12 months) who presented with signs and symptoms attributable to a skull fracture. We determined rates of skeletal survey, dedicated ophthalmologic examination and abdominal injury screening, rates of injury identification by testing and reports to child protective services. RESULTS: A total of 215 infants underwent abuse consultation for apparently isolated skull fractures. Skeletal surveys were performed in 201 subjects (93.4%) and identified additional fractures in 12 (5.6%; 95% confidence interval, 2.9-9.6%). Patient age, trauma history, and fracture type (simple/complex) were not sensitive predictors of finding additional fractures on skeletal survey. Only one additional fracture was associated with clinical signs or symptoms. Dedicated ophthalmologic examination was undertaken in 100 subjects (46.5%); one child had retinal hemorrhages. Hepatic transaminases were obtained in 135 subjects (62.7%), and 5 subjects (2.3%) had abdominal computed tomography. No abdominal injuries were identified. A total of 146 subjects (67.9%) were reported to child protective services. CONCLUSION: Infants with apparently isolated skull fractures are an important fraction of consultations for physical abuse. Additional fractures are identified in a small subset of the skeletal surveys completed in these children.

Abstract/Description

Siblings and other children who share a home with a physically abused child are thought to be at high risk for abuse, but rates of injury in these contact children are unknown and screening of contacts is highly variable. Our objective was to determine the prevalence of abusive injuries identified by a common screening protocol among contacts of physically abused children.
