RESUMEN
BACKGROUND: Head computed tomography (CT) is the current standard of care for evaluating infants at high risk of abusive head trauma. OBJECTIVE: To both assess the feasibility of using a previously developed magnetic resonance imaging (MRI) brain injury screen (MRBRscreen) in the acute care setting in place of head CT to identify intracranial hemorrhage in high-risk infants and to compare the accuracy of a rapid imaging pulse sequence (single-shot T2 fast spin echo [ssT2FSE]) to a conventional pulse sequence (conventional T2 fast spin echo [conT2FSE]). MATERIALS AND METHODS: This was a quality improvement initiative to evaluate infants <12 months of age who were screened for intracranial hemorrhage using an MRBRscreen as part of clinical care. The MRBRscreen included axial conT2FSE, axial gradient recalled echo, coronal T1-weighted inversion recovery, axial diffusion-weighted image and an axial ssT2FSE. A comparison of ssT2FSE to conT2FSE with respect to lesion detection was also performed. RESULTS: Of 158 subjects, the MRBRscreen was able to be completed in 155 (98%); 9% (14/155) were abnormal. Ninety-four percent (137/145) of subjects underwent only an MRBRscreen and avoided both radiation from head CT and sedation from MRI. The axial ssT2FSE and conT2FSE results were congruent 99% of the time. CONCLUSION: An MRBRscreen in place of a head CT is feasible and potentially could decrease head CT use by more than 90% in this population. Using a rapid ssT2FSE in place of a conT2FSE can reduce total scan time without losing lesion detection. If an MRBRscreen is readily available, physicians' threshold to perform neuroimaging may be lowered and lead to earlier detection of abusive head trauma.

BACKGROUND: Abusive head trauma (AHT) is an important cause of morbidity in infants. Identifying which well-appearing infants are at risk for AHT and need neuroimaging is challenging, and concern about radiation exposure limits the use of head CT. Availability of an MRI protocol that is highly sensitive for intracranial hemorrhage would allow for AHT screening of well-appearing infants without exposing them to radiation. OBJECTIVE: To develop a screening MRI protocol to identify intracranial hemorrhage in well-appearing infants at risk for AHT. MATERIALS AND METHODS: Infants enrolled in a parent study of well-appearing infants at increased risk for AHT were eligible for the current study if they underwent both head CT and conventional brain MRI. A derivation cohort of nine infants with AHT was used to identify sequences that provided the highest sensitivity for intracranial hemorrhage. A validation cohort of 78 infants including both controls with normal neuroimaging and cases with AHT was used to evaluate the accuracy of the selected sequences. RESULTS: Three pulse sequences - axial T2, axial gradient recalled echo (GRE) and coronal T1-W inversion recovery - were 100% sensitive for intracranial hemorrhage in the derivation cohort. The same sequences were 100% sensitive (25/25) and 83% specific (44/53) for intracranial hemorrhage in the validation cohort. CONCLUSION: A screening MRI protocol including axial T2, axial GRE and coronal T1-W inversion recovery sequences is highly sensitive for intracranial hemorrhage and may be useful as a screening tool to differentiate well-appearing infants at risk for AHT who should undergo head CT from those who can safely be discharged without head CT. Additional research is needed to evaluate the feasibility of this approach in clinical practice.

OBJECTIVE: To determine whether D-dimer would be increased in children with traumatic brain injury (TBI), specifically mild abusive head trauma. STUDY DESIGN: D-dimer was measured using multiplex bead technology in 195 children <4 years old (n = 93 controls without TBI, n = 102 cases with TBI) using previously collected serum. D-dimer was then measured prospectively in a clinical setting in 44 children (n = 24 controls, n = 20 cases). Receiver operator curves were generated for prospective data. RESULTS: In both the retrospective and prospective cohorts, median (25th-75th percentile) D-dimer was significantly higher in cases vs controls. A receiver operator curve demonstrated an area under the curve of 0.91 (95% CI 0.83-0.99) in the prospective cohort. At a cut-off of 0.59 µg/L, the sensitivity and specificity for identification of a case was 90% and 75%, respectively. CONCLUSIONS: Our data suggest that serum D-dimer may be able to be used to identify which young children at risk for abusive head trauma might benefit from a head computed tomography or other additional evaluation. Additional data are needed to better identify the clinical scenarios that may result in false positive or false negative D-dimer concentrations.

OBJECTIVE: To assess the accuracy of an International Classification of Diseases (ICD) code-based operational case definition for abusive head trauma (AHT). METHODS: Subjects were children <5â years of age evaluated for AHT by a hospital-based Child Protection Team (CPT) at a tertiary care paediatric hospital with a completely electronic medical record (EMR) system. Subjects were designated as non-AHT traumatic brain injury (TBI) or AHT based on whether the CPT determined that the injuries were due to AHT. The sensitivity and specificity of the ICD-based definition were calculated. RESULTS: There were 223 children evaluated for AHT: 117 AHT and 106 non-AHT TBI. The sensitivity and specificity of the ICD-based operational case definition were 92% (95% CI 85.8 to 96.2) and 96% (95% CI 92.3 to 99.7), respectively. All errors in sensitivity and three of the four specificity errors were due to coder error; one specificity error was a physician error. CONCLUSIONS: In a paediatric tertiary care hospital with an EMR system, the accuracy of an ICD-based case definition for AHT was high. Additional studies are needed to assess the accuracy of this definition in all types of hospitals in which children with AHT are cared for.

OBJECTIVE: The study sought to develop and evaluate an electronic health record-based child abuse clinical decision support system in 2 general emergency departments. MATERIALS AND METHODS: A combination of a child abuse screen, natural language processing, physician orders, and discharge diagnoses were used to identify children <2 years of age with injuries suspicious for physical abuse. Providers received an alert and were referred to a physical abuse order set whenever a child triggered the system. Physician compliance with clinical guidelines was compared before and during the intervention. RESULTS: A total of 242 children triggered the system, 86 during the preintervention and 156 during the intervention. The number of children identified with suspicious injuries increased 4-fold during the intervention (P < .001). Compliance was 70% (7 of 10) in the preintervention period vs 50% (22 of 44) in the intervention, a change that was not statistically different (P = .55). Fifty-two percent of providers said that receiving the alert changed their clinical decision making. There was no relationship between compliance and provider or patient demographics. CONCLUSIONS: A multifaceted child abuse clinical decision support system resulted in a marked increase in the number of young children identified as having injuries suspicious for physical abuse in 2 general emergency departments. Compliance with published guidelines did not change; we hypothesize that this is related to the increased number of children identified with suspicious, but less serious injuries. These injuries were likely missed preintervention. Tracking compliance with guidelines over time will be important to assess whether compliance increases as physician comfort with evaluation of suspected physical abuse in young children improves.

Objective: Physical abuse is a leading cause of pediatric morbidity and mortality. Physicians do not consistently screen for abuse, even in high-risk situations. Alerts in the electronic medical record may help improve screening rates, resulting in early identification and improved outcomes. Methods: Triggers to identify children < 2 years old at risk for physical abuse were coded into the electronic medical record at a freestanding pediatric hospital with a level 1 trauma center. The system was run in "silent mode"; physicians were unaware of the system, but study personnel received data on children who triggered the alert system. Sensitivity, specificity, and negative and positive predictive values of the child abuse alert system for identifying physical abuse were calculated. Results: Thirty age-specific triggers were embedded into the electronic medical record. From October 21, 2014, through April 6, 2015, the system was in silent mode. All 226 children who triggered the alert system were considered subjects. Mean (SD) age was 9.1 (6.5) months. All triggers were activated at least once. Sensitivity was 96.8% (95% CI, 92.4-100.0%), specificity was 98.5% (95% CI, 98.3.5-98.7), and positive and negative predictive values were 26.5% (95% CI, 21.2-32.8%) and 99.9% (95% CI, 99.9-100.0%), respectively, for identifying children < 2 years old with possible, probable, or definite physical abuse. Discussion/Conclusion: Triggers embedded into the electronic medical record can identify young children with who need to be evaluated for physical abuse with high sensitivity and specificity.

Objective: To evaluate the effect of a previously validated electronic health record-based child abuse trigger system on physician compliance with clinical guidelines for evaluation of physical abuse. Methods: A randomized controlled trial (RCT) with comparison to a preintervention group was performed. RCT-experimental subjects' providers received alerts with a direct link to a physical abuse-specific order set. RCT-control subjects' providers had no alerts, but could manually search for the order set. Preintervention subjects' providers had neither alerts nor access to the order set. Compliance with clinical guidelines was calculated. Results: Ninety-nine preintervention subjects and 130 RCT subjects (73 RCT-experimental and 57 RCT-control) met criteria to undergo a physical abuse evaluation. Full compliance with clinical guidelines was 84% pre-intervention, 86% in RCT-control group, and 89% in RCT-experimental group. The physical abuse order set was used 43 times during the 7-month RCT. When the abuse order set was used, full compliance was 100%. The proportion of cases in which there was partial compliance decreased from 10% to 3% once the order set became available (P = .04). Male gender, having >10 years of experience and completion of a pediatric emergency medicine fellowship were associated with increased compliance. Discussion/Conclusion: A child abuse clinical decision support system comprised of a trigger system, alerts and a physical abuse order set was quickly accepted into clinical practice. Use of the physical abuse order set always resulted in full compliance with clinical guidelines. Given the high baseline compliance at our site, evaluation of this alert system in hospitals with lower baseline compliance rates will be more valuable in assessing the efficacy in adherence to clinical guidelines for the evaluation of suspected child abuse.

BACKGROUND: Routine child abuse screening is an approach to early identification of abuse. Previous studies evaluated paper-based screens; the widespread use of electronic health records suggests that screening is more likely to succeed if integrated into the electronic record. OBJECTIVE: To implement an electronic health record-based child abuse screen in a diverse hospital system and to evaluate the screening rate, rate of positive screens, and number of reports to Child Protective Services and assess whether hospital and patient characteristics are associated with these rates. PARTICIPANTS AND SETTING: Children <13 years of age evaluated at one of 13 Emergency Departments within University of Pittsburgh Medical Center Health System. METHODS: A previously validated child abuse screen was slightly modified and integrated into Cerner. Multivariable logistic regression models were used to estimate the odds of the outcomes of interest, controlling for key covariates. RESULTS: Of 17,163 eligible children: 68% received the screen of which 1.9% were positive. The rate of reports to Child Protective Services was higher among children who were screened (p < 0.0001). Younger children were more likely to be screened, have a positive screen, and have a report filed. There was no difference in the odds of being screened according to hospital teaching status, size or urban vs rural location. CONCLUSIONS: A child abuse screening tool can be integrated into the electronic health record in a large health-care network. The increased number of reports among children who were screened suggests that screening facilitates detection of suspected maltreatment.

Importance: Abusive head trauma is the leading cause of death from physical abuse. Missing the diagnosis of abusive head trauma, particularly in its mild form, is common and contributes to increased morbidity and mortality. Serum biomarkers may have potential as quantitative point-of-care screening tools to alert physicians to the possibility of intracranial hemorrhage. Objective: To identify and validate a set of biomarkers that could be the basis of a multivariable model to identify intracranial hemorrhage in well-appearing infants using the Ziplex System. Design, Setting, and Participants: Binary logistic regression was used to develop a multivariable model incorporating 3 serum biomarkers (matrix metallopeptidase-9, neuron-specific enolase, and vascular cellular adhesion molecule-1) and 1 clinical variable (total hemoglobin). The model was then prospectively validated. Multiplex biomarker measurements were performed using Flow-Thru microarray technology on the Ziplex System, which has potential as a point-of-care system. The model was tested at 3 pediatric emergency departments in level I pediatric trauma centers (Children's Hospital of Pittsburgh of University of Pittsburgh Medical Center, Pittsburgh, Pennsylvania; Primary Children's Hospital, Salt Lake City, Utah; and Lurie Children's Hospital, Chicago, Illinois) among well-appearing infants who presented for care owing to symptoms that placed them at increased risk of abusive head trauma. The study took place from November 2006 to April 2014 at Children's Hospital of Pittsburgh, June 2010 to August 2013 at Primary Children's Hospital, and January 2011 to August 2013 at Lurie Children's Hospital. Main Outcomes and Measures: A mathematical model that can predict acute intracranial hemorrhage in infants at increased risk of abusive head trauma. Results: The multivariable model, Biomarkers for Infant Brain Injury Score, was applied prospectively to 599 patients. The mean (SD) age was 4.7 (3.1) months. Fifty-two percent were boys, 78% were white, and 8% were Hispanic. At a cutoff of 0.182, the model was 89.3% sensitive (95% CI, 87.7-90.4) and 48.0% specific (95% CI, 47.3-48.9) for acute intracranial hemorrhage. Positive and negative predictive values were 21.3% and 95.6%, respectively. The model was neither sensitive nor specific for atraumatic brain abnormalities, isolated skull fractures, or chronic intracranial hemorrhage. Conclusion and Relevance: The Biomarkers for Infant Brain Injury Score, a multivariable model using 3 serum biomarker concentrations and serum hemoglobin, can identify infants with acute intracranial hemorrhage. Accurate and timely identification of intracranial hemorrhage in infants without a history of trauma in whom trauma may not be part of the differential diagnosis has the potential to decrease morbidity and mortality from abusive head trauma.

BACKGROUND: Abusive head trauma is the leading cause of death from physical abuse. Misdiagnosis of abusive head trauma as well as other types of brain abnormalities in infants is common and contributes to increased morbidity and mortality. We previously derived the Pittsburgh Infant Brain Injury Score (PIBIS), a clinical prediction rule to assist physicians deciding which high-risk infants should undergo computed tomography of the head. METHODS: Well-appearing infants 30 to 364 days of age with temperature <38.3°C, no history of trauma, and a symptom associated with an increased risk of having a brain abnormality were eligible for enrollment in this prospective, multicenter clinical prediction rule validation. By using a predefined neuroimaging paradigm, subjects were classified as cases or controls. The sensitivity, specificity, and negative and positive predictive values of the rule for prediction of brain injury were calculated. RESULTS: A total of 1040 infants were enrolled: 214 cases and 826 controls. The 5-point PIBIS included abnormality on dermatologic examination (2 points), age ≥3.0 months (1 point), head circumference >85th percentile (1 point), and serum hemoglobin <11.2g/dL (1 point). At a score of 2, the sensitivity and specificity for abnormal neuroimaging was 93.3% (95% confidence interval 89.0%-96.3%) and 53% (95% confidence interval 49.3%-57.1%), respectively. CONCLUSIONS: Our data suggest that the PIBIS accurately identifies infants who would benefit from neuroimaging to evaluate for brain injury. An implementation analysis is needed before the PIBIS can be integrated into clinical practice.

OBJECTIVE: We aimed to examine abusive head trauma (AHT) incidence before, during and after the recession of 2007-2009 in 3 US regions and assess the association of economic measures with AHT incidence. METHODS: Data for children <5 years old diagnosed with AHT between January 1, 2004, and December 31, 2012, in 3 regions were linked to county-level economic data using an ecologic time series analysis. Associations between county-level AHT rates and recession period as well as employment growth, mortgage delinquency, and foreclosure rates were examined using zero-inflated Poisson regression models. RESULTS: During the 9-year period, 712 children were diagnosed with AHT. The mean rate of AHT per 100,000 child-years increased from 9.8 before the recession to 15.6 during the recession before decreasing to 12.8 after the recession. The AHT rates after the recession were higher than the rates before the recession (incidence rate ratio 1.31, P = .004) but lower than rates during the recession (incidence rate ratio 0.78, P = .005). There was no association between the AHT rate and employment growth, mortgage delinquency rates, or foreclosure rates. CONCLUSIONS: In the period after the recession, AHT rate was lower than during the recession period yet higher than the level before the recession, suggesting a lingering effect of the economic stress of the recession on maltreatment risk.

BACKGROUND: Child physical abuse is an important cause of morbidity and mortality in young children. The skeletal survey (SS) is considered a mandatory part of the evaluation for suspected physical abuse in young children. Literature suggests that a follow-up SS performed 10 to 21 days after the initial SS can provide important additional information, but previous studies evaluating the follow-up SS have been small and included very selective patient populations. METHODS: A retrospective descriptive study of a consecutive sample of children who underwent an initial SS and a follow-up SS at a single children's hospital during a 7-year period. Data on demographics, clinical presentation, results, and effect of the follow-up SS on clinical diagnosis were collected. RESULTS: Of the 1470 children who underwent an initial SS, 11% (169 of 1470 children) also underwent a follow-up SS. The mean age of the children who underwent both an initial SS and a follow-up SS was 5.8 months. Fourteen percent of the follow-up SS identified previously unrecognized fractures; all of which were healing. There were eight children in whom the information obtained from the follow-up SS resulted in a diagnosis of definite physical abuse; all eight children were younger than 12 months, and in six of these cases, the initial SS did not demonstrate any fractures. CONCLUSION: Only a small proportion of children who undergo an initial SS also undergo a follow-up SS. The relatively high proportion of follow-up SS that demonstrated previously unrecognized fracture(s), the young age of children undergoing the follow-up SS, and the high morbidity and mortality of unrecognized/missed child physical abuse in this age group suggest that the follow-up SS should be a routine part of the evaluation of child physical abuse. LEVEL OF EVIDENCE: III, observational study.

OBJECTIVES: To describe the prevalence of retinal hemorrhage (RH) in children without intracranial injury who are being evaluated for abusive head trauma and to validate previously derived criteria for identifying patients within this population who are at low risk of having RH on dilated eye examination. DESIGN: Medical record review. SETTING: Children's Hospital of Pittsburgh of University of Pittsburgh Medical Center from January 1, 2006, to April 30, 2010. PARTICIPANTS: One hundred ninety-four infants and children evaluated for physical abuse by the hospital Child Protection Team who did not have intracranial injury and who underwent a dilated eye examination to evaluate for RH. MAIN OUTCOME MEASURE: Number of children with RH who met a set of low-risk criteria: no intracranial hemorrhage with or without a simple, nonoccipital skull fracture, normal mental status, and no bruising on the head or face. RESULTS: Of the 194 patients without intracranial injury who underwent dilated eye examination, 141 children (72.7%) met low-risk criteria. None of these 141 patients had RH. Of the 53 participants who did not meet low-risk criteria, 2 children (3.8%) had RH. CONCLUSIONS: In children evaluated for physical abuse who fulfill a set of low-risk criteria, the dilated eye examination should not be a necessary component of the abuse evaluation. Use of these criteria can significantly decrease the number of children who need to undergo a dilated eye examination as part of an evaluation for abusive head trauma.

OBJECTIVES: The goals were to assess the use of the skeletal survey (SS) to evaluate for physical abuse in a large consecutive sample, to identify characteristics of children most likely to have unsuspected fractures, and to determine how often SS results influenced directly the decision to make a diagnosis of abuse. METHODS: A retrospective, descriptive study of a consecutive sample of children who underwent an SS at a single children's hospital over 4 years was performed. Data on demographic characteristics, clinical presentation, SS results, and effects of SS results on clinical diagnoses were collected. A positive SS result was defined as a SS which identified a previously unsuspected fracture(s). RESULTS: Of the 703 SSs, 10.8% yielded positive results. Children <6 months of age, children with an apparent life-threatening event or seizure, and children with suspected abusive head trauma had the highest rates of positive SS results. Of children with positive SS results, 79% had ≥1 healing fracture. CONCLUSIONS: This is the largest study to date to describe the use of the SS. Almost 11% of SS results were positive. The SS results influenced directly the decision to make a diagnosis of abuse for 50% of children with positive SS results. These data, combined with the high morbidity rates for missed abuse and the large proportion of children with healing fractures detected through SS, suggest that broader use of SS, particularly for high-risk populations, may be warranted.

OBJECTIVE: To evaluate the rate of abusive head trauma (AHT) in 3 regions of the United States before and during an economic recession and assess whether there is a relationship between the rate of AHT and county-level unemployment rates. METHODS: Clinical data were collected for AHT cases diagnosed in children younger than 5 years from January 1, 2004 until June 30, 2009, by hospital-based child protection teams within 3 geographic regions. The recession was defined as December 1, 2007 through June 30, 2009. Quarterly unemployment rates were collected for every county in which an AHT case occurred. RESULTS: During the 5½-year study period, a total of 422 children were diagnosed with AHT in a 74-county region. The overall rate of AHT increased from 8.9 in 100,000 (95% confidence interval [CI]: 7.8-10.0) before the recession to 14.7 in 100,000 (95% CI: 12.5-16.9) during the recession (P < .001). There was no difference in the clinical characteristics of subjects in the prerecession versus recession period. There was no relationship between the rate of AHT and county-level unemployment rates. CONCLUSIONS: The rate of AHT increased significantly in 3 distinct geographic regions during the 19 months of an economic recession compared with the 47 months before the recession. This finding is consistent with our understanding of the effect of stress on violence. Given the high morbidity and mortality rates for children with AHT, these results are concerning and suggest that prevention efforts might need to be increased significantly during times of economic hardship.
