Abstract
BACKGROUND This scoping review aimed to overview studies that used administrative data linkage in the context of child maltreatment to improve our understanding of the value that data linkage may confer for policy, practice, and research. METHODS We searched MEDLINE, Embase, PsycINFO, CINAHL, and ERIC electronic databases in June 2019 and May 2020 for studies that linked two or more datasets (at least one of which was administrative in nature) to study child maltreatment. We report findings with numerical and narrative summary. RESULTS We included 121 studies, mainly from the United States or Australia and published in the past decade. Data came primarily from social services and health sectors, and linkage processes and data quality were often not described in sufficient detail to align with current reporting guidelines. Most studies were descriptive in nature and research questions addressed fell under eight themes: descriptive epidemiology, risk factors, outcomes, intergenerational transmission, predictive modelling, intervention/service evaluation, multi-sector involvement, and methodological considerations/advancements. CONCLUSIONS Included studies demonstrated the wide variety of ways in which data linkage can contribute to the public health response to child maltreatment. However, how research using linked data can be translated into effective service development and monitoring, or targeting of interventions, is underexplored in terms of privacy protection, ethics and governance, data quality, and evidence of effectiveness.

Abstract
IMPORTANCE It is important to recognize presenting features and factors associated with mortality in abusive head trauma (AHT) owing to the severity of the diagnosis and the necessity for prompt action. OBJECTIVE To describe the prevalence and economic burden of AHT and identify factors associated with mortality. DESIGN, SETTING, AND PARTICIPANTS This retrospective, cross-sectional study used the Nationwide Emergency Department Sample database to identify all emergency department visits in the US for patients younger than 5 years with a primary diagnosis of abusive head trauma between January 1, 2006, and December 31, 2018. This study was conducted in 2021. MAIN OUTCOMES AND MEASURES Prevalence, demographic characteristics, clinical characteristics, mortality, and economic burden associated with AHT. Weighted national estimates were calculated using sampling weights provided in the Nationwide Emergency Department Sample database. RESULTS From 2006 to 2018, there were an estimated 12 287 cases of emergency department visits in the US for patients younger than 5 years with a primary diagnosis of AHT. The estimated number of AHT cases decreased by 672 (95% CI, 403-940; P < .001) from 2006 to 2018. The incidence decreased by 6.7% each year (incidence rate ratio, 0.93; 95% CI, 0.93-0.94; P < .001) between 2006 and 2018. During the course of a hospital visit, 646 patients (5.3%) died. The majority of patients with a diagnosis of AHT were younger than 1 year (n = 7046; 57.3%), were male (n = 7268; 59.2%) and had Medicaid insurance (n = 8585; 70.0%). After controlling for demographic characteristics, factors associated with increased mortality were age greater than 1 year (odds ratio [OR], 2.45; 95% CI, 1.50-3.99; P < .001), first or second income quartile (OR, 1.78; 95% CI, 1.08-2.91; P = .02), midwestern United States (OR, 2.04; 95% CI, 1.04-4.00; P = .04), level 1 trauma center (OR, 2.69; 95% CI, 1.07-6.75; P = .04), orbital fracture (OR, 15.38; 95% CI, 2.41-98.18; P = .004), cerebral edema (OR, 8.49; 95% CI, 5.57-12.93; P < .001), intracranial hemorrhage (OR, 4.27; 95% CI, 1.71-10.67; P = .002), hypoxic ischemic brain injury (OR, 4.16; 95% CI, 2.13-8.10; P < .001), skull fractures (OR, 3.20; 95% CI, 1.76-5.82; P < .001), subarachnoid hemorrhage (OR, 2.43; 95% CI, 1.22-4.83; P = .01), retinal hemorrhage (OR, 2.17; 95% CI, 1.40-3.38; P < .001), and subdural hemorrhage (OR, 2.05; 95% CI, 1.05-3.98; P = .04). CONCLUSIONS AND RELEVANCE This study's findings suggest that health care disparities may be present in the treatment of AHT. Recognizing factors suggested in this investigation to be associated with higher mortality, public health efforts should be targeted toward low-income areas and in the midwestern United States.

Högberg U. Transfer of knowledge to diagnose infant abuse and its incidence - a time-series analysis from Sweden. Implement Sci 2022; 17:15. [PMID: 35120543 PMCID: PMC8815122 DOI: 10.1186/s13012-022-01188-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2021] [Accepted: 01/05/2022] [Indexed: 12/04/2022] Open
Abstract
Aim To analyse the transfer of knowledge on how to detect physical abuse, especially shaken baby syndrome/abusive head trauma (SBS/AHT), and its association to trends in infant abuse diagnoses (maltreatment and assault). Methods Design: retrospective population-based and quasi-experimental. Setting: Sweden 1987–2019. Patients: Children below age 1 year, selected from the National Patient Register (n = 1150). Exposures: Literature search for transfer of knowledge by diffusion, dissemination and implementation, and whether supportive or disruptive of the SBS/AHT paradigm. Main outcome measure: Abuse diagnoses (maltreatment or assault). Analyses: Incidence rate, incidence rate ratio (IRR). Results The overall incidence rate of abuse was 32.23 per 100,000 during the years 1987–2019. It was rather stable 1987–2000. The SBS diagnosis was introduced in the late 1990s. A comprehensive increase of transfer of knowledge on physical abuse, specifically on SBS/AHT and dangers of shaking, took place from 2002 and onward through diffusion, dissemination and implementation. Maltreatment diagnoses, but not assault diagnosis, increased steeply during 2002–2007, peaking in 2008–2013 [IRR 1.63 (95% confidence interval 1.34–1.98)]. Transfer of disruptive knowledge on SBS/AHT during the period 2014–2019 was associated with a decline in maltreatment diagnoses [IRR 0.84 (95% confidence interval 0.71–0.99)]. Conclusion An increase in maltreatment diagnoses was associated with transfer of supportive knowledge of the SBS/AHT paradigm, while a decline occurred toward the end of the study period, which might indicate a burgeoning de-implementation process.

Abstract
OBJECTIVES To assess cases with rib fractures in infants under observation for or with an abuse diagnosis, and to compare risk factors with that in infants with fractures but no abuse diagnosis. METHODS Design was case-series and register case-control of infants (aged <1 year) with rib fractures. Data was clinical records for the case-series (n = 26) and from national health registers for the case-controls (n = 28 and n = 31). Outcome measures were maternal and perinatal characteristics, reasons for appointment, examination, diagnoses, blood tests, and radiologic findings. RESULTS The case-series had a median age of 70 days. A majority were detected through a skeletal survey for abuse investigation. Sixteen were boys, three were preterm and six were small-for-gestational age. Three carers had noticed popping sound from the chest; no infants showed signs of pain at physical examination. Mean number of fractures was 4.2, and 24 had callus. Bone mineralisation was scarcely reported. Metabolic panel was not uniformly analysed. The register case-control had a median age of 76 days, sharing risk factors such as maternal overweight/obesity, male sex, prematurity, and being small-for-gestational age. Cases more often had subdural haemorrhage, retinal haemorrhage, or long-bone fractures, controls more often had neonatal morbidity, respiratory infection, or a fall accident. Detection of fracture at time of a major surgery (n = 6) and rickets/vitamin D deficiency (n = 5) appeared in both groups, but was delayed among the cases. CONCLUSIONS Rib fractures in young infants, diagnosed as abuse, are usually asymptomatic and healing. A substantial proportion had metabolic risk factors, suggesting false positive cases.

Abstract
INTRODUCTION The purpose was to determine if an age based, local diagnostic reference level for paediatric skeletal surveys could be established using retrospective data. METHODS All children below two years of age referred for a primary skeletal survey as a result of suspected physical abuse during 2017 or 2018 (n = 45) were retrospectively included from a large Danish university hospital. The skeletal survey protocol included a total of 33 images. Dose Area Product (DAP) and acquisition parameters for all images were recorded from the Picture Archival and Communication System (PACS) and effective dose was estimated. The 75th percentile for DAP was considered as the diagnostic reference level (DRL). RESULTS The 75th percentile for DAP was 314 mGy∗cm2, 520 mGy∗cm2 and 779 mGy∗cm2 for children <1 month, 1-11 months and 12 < 24 months of age respectively. However, only the age group 1-11 months had a sufficient number of children (n = 27) to establish a local DRL. Thus, for the other groups the DAP result must be interpreted with caution. Effective dose was 0.19, 0.26 and 0.18 mSv for children <1, 1-11 months and 12 < 24 months of age respectively. CONCLUSION For children between 1 and 11 months of age, a local diagnostic reference level of 520 mGy∗cm2 was determined. This may be used as an initial benchmark for primary skeletal surveys as a result of suspected physical abuse for comparison and future discussion. IMPLICATIONS FOR PRACTICE While the data presented reflects the results of a single department, the suggested diagnostic reference level may be used as a benchmark for other departments when auditing skeletal survey radiation dose.

Abstract
BACKGROUND Many physicians regard the combination of encephalopathy, subdural haemorrhage (SDH), retinal haemorrhage (RH), rib fractures, and classical metaphyseal lesions (CML) as highly specific for abusive head trauma (AHT). However, without observed abuse or other criteria that are independent of these findings, bias risk is high. METHODS Infants subjected for examination under the suspicion of maltreatment during the period 1997-2014 were identified in the National Patient Registry, International Classification of Diseases (ICD-10 SE). The medical records were scrutinized for identification of cases of witnessed or admitted physical abuse by shaking. The main outcome measures were occurrence of SDH, RH, fractures and skin lesions. RESULTS All identified 36 infants had been shaken, and for 6, there was information indicating blunt force impact immediately after shaking. In 30 cases, there were no findings of SDH or RH, rib fractures, or CMLs. Six infants had finding(s) suggestive of physical abuse, two with possible acute intracranial pathology. One infant with combined shaking and impact trauma had hyperdense SDH, hyperdense subarachnoid haemorrhage, suspected cortical vein thrombosis, RH, and bruises. Another infant abused by shaking had solely an acute subarachnoid haemorrhage. Both had pre-existing vulnerability. The first was born preterm and had non-specific frontal subcortical changes. The other had bilateral chronic SDH/hygroma. CONCLUSIONS The present findings do not support the hypothesis that acute SDH or RH can be caused by isolated shaking of a healthy infant. However, they do suggest that abuse by shaking may cause acute intracranial haemorrhage with RH in infants with certain risk factors.

Abstract
Objectives To explore parents’ experiences of seeking health care for their children and instead being accused by healthcare professionals of Shaken Baby Syndrome/Abusive Head Trauma (SBS/AHT), being reported to Social Services, undergoing judiciary processing, and the impact of these events on family (dis)integration. Methods Design: A qualitative study based on qualitative content analysis. Participants: Twelve parents in Sweden, mothers and fathers, seeking health care for their infants, encountering allegations of SBS/AHT, losing custody of their infants, and being subjected to a judiciary process, and finally regaining custody of their children. Data collection: In-depth interviews. Results An overarching theme ‘Fighting for protection of their child after being trapped by doctors’ and four sub-themes were developed to reflect the parents’ experiences, reactions and interpretations. The first sub-theme, ‘Being accused of injuring the child’, illuminated the shock experienced when seeking care and instead being accused of being a perpetrator. The second, ‘Chaos and powerlessness’, refers to the emotions experienced when losing custody of the child and being caught in the enforcement of legislation by the authorities. The third, ´The unified fight against the doctors’ verdict´, illustrates the parents’ fight for innocence, their worry for the lost child, and their support and resistance. The fourth, ‘The wounded posttraumatic growth’, describes the emotions, grief, panic, anxiety, and challenges in reuniting the family, but also the parents’ reflections on personal growth. Unanimously, they had experienced the authorities’ inability to reconsider, and expressed a deep mistrust of paediatric care. Conclusions Being wrongly accused of child abuse and alleged SBS/AHT evoked emotions of intense stress, but parents endured because of a successful fight to regain custody of their child. However, the trauma had a long-term impact on their lives with residual posttraumatic stress symptoms and mistrust towards healthcare services and the authorities. The results provide important inferences for restoring system failures within child protection services.

Abstract
BACKGROUND AND AIMS Identification of child abuse involves a medical investigation and assessment of problems related to social environment and upbringing and might necessitate out-of-home care. The objective of this study was to analyse infants placed in out-of-home care in Sweden by incidence, medical diagnoses, and perinatal factors. METHODS This was a population-based register study of infants born in Sweden 1997 to 2014. Data were retrieved from registers at the Swedish National Board of Health and Welfare and Statistics Sweden. Outcome measures were out-of-home care categories: (a) "Problems Related to Social Environment/Upbringing", (b) "Abuse diagnoses without SDH (subdural haemorrhage), RH (retinal haemorrhage), rib fracture, or long bone fracture", and (c) "SDH, RH, rib fracture, or long bone fracture." As a reference population, we randomly selected infants without medical diagnoses born the same year. RESULTS Overall incidence of out-of-home care was 402 per 100 000. For subcategories (a), (b), and (c), the incidences were 14.8 (n = 273), 3.77 (n = 70), and 9.83 (n = 182) per 100 000, respectively. During the study period, the first remained unchanged; the latter two have been increasing. Compared with other reasons for out-of-home care, children in category (c), "SDH, RH, rib fracture, or long bone fracture", had increased odds of being boys (adjusted odds ratio [aOR] 1.60; 95% confidence interval [CI], 1.08-2.38) and decreased odds of having a mother being single (aOR 0.49; 95% CI, 0.32-0.75) and a smoker (aOR 0.60; 95% CI, 0.37-0.96). Compared with the reference population, children in this category were more often twin born (7.7% versus 2.8%), preterm (18.5% versus 5.5%), and small-for-gestational age (5.2% versus 2.1%). CONCLUSION SDH, RH, rib fracture, or long bone fracture constitute a minor part of medical diagnoses for infants entered in out-of-home care, but have been increasing, both in numbers and proportion. Overdiagnosis of abuse might be a possible reason but cannot be ascertained by this study design.

[PMID: 30566429 PMCID: PMC6300197 DOI: 10.1371/journal.pone.0208033] [Citation(s) in RCA: 27] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2018] [Accepted: 11/10/2018] [Indexed: 11/18/2022] Open
Abstract
Background The aim of this study was to assess the incidence of fractures in infancy, overall and by type of fracture, its association with accidents, metabolic bone disease risk factors, and abuse diagnosis. Methods The design was a population-based register study in Sweden. Participants: Children born 1997–2014, 0–1 years of age diagnosed with fracture-diagnosis according to International Classification of Diseases (ICD10) were retrieved from the National Patient Register and linked to the Swedish Medical Birth Register and the Death Cause Register. Main outcome measures were fractures of the skull, long bone, clavicle and ribs, categorized by age (younger or older than 6 months), and accident or not. Findings The incidence of fractures during infancy was 251 per 100 000 infants (n = 4663). Major fracture localisations were long bone (44·9%), skull (31·7%), and clavicle (18·6%), while rib fractures were few (1·4%). Fall accidents were reported among 71·4%. One-third occurred during the first 6 months. Metabolic bone disease risk factors, such as maternal obesity, preterm birth, vitamin D deficiency, rickets, and calcium metabolic disturbances, had increased odds of fractures of long bones and ribs in early infancy (0–6 months): birth 32–36 weeks and long bone fracture [AOR 2·13 (95%CI 1·67–2·93)] and rib fracture [AOR 4·24 (95%CI 1·40–12·8)]. Diagnosis of vitamin D deficiency/rickets/disorders of calcium metabolism had increased odds of long bone fracture [AOR 49·5 (95%CI 18·3–134)] and rib fracture [AOR 617 (95%CI 162–2506)]. Fractures without a reported accident had higher odds of metabolic risk factors than those with reported accidents. Abuse diagnosis was registered in 105 infants, with overrepresentation of preterm births, multiple births and small-for-gestational age. Interpretation Metabolic bone disease risk factors are strongly associated with fractures of long bone and ribs in early infancy. Fracture cases with abuse diagnosis had a metabolic bone risk factor profile.

Abstract
Objectives To analyse subdural haemorrhage (SDH) during infancy in Sweden by incidence, SDH category, diagnostic distribution, age, co-morbidity, mortality, and maternal and perinatal risk factors; and its association with accidents and diagnosis of abuse. Methods A Swedish population-based register study comprising infants born between 1997 and 2014, 0–1 years of age, diagnosed with SDH-diagnoses according to the (International Classification of Diseases, 10th version (ICD10), retrieved from the National Patient Register and linked to the Medical Birth Register and the Death Cause Register. Outcome measures were: 1) Incidence and distribution, 2) co-morbidity, 3) fall accidents by SDH category, 4) risk factors for all SDHs in the two age groups, 0–6 and 7–365 days, and for ICD10 SDH subgroups: S06.5 (traumatic SDH), I62.0 (acute nontraumatic), SDH and abuse diagnosis. Results Incidence of SDH was 16·5 per 100 000 infants (n = 306). Median age was 2·5 months. For infants older than one week, the median age was 3·5 months. Case fatality was 6·5%. Male sex was overrepresented for all SDH subgroups. Accidental falls were reported in 1/3 of the cases. One-fourth occurred within 0–6 days, having a perinatal risk profile. For infants aged 7–365 days, acute nontraumatic SDH was associated with multiple birth, preterm birth, and small-for-gestational age. Fourteen percent also had an abuse diagnosis, having increased odds of being born preterm, and being small-for-gestational age. Conclusions The incidence was in the range previously reported. SDH among newborns was associated with difficult birth and neonatal morbidity. Acute nontraumatic SDH and SDH with abuse diagnosis had similar perinatal risk profiles. The increased odds for acute nontraumatic SDH in twins, preterm births, neonatal convulsions or small-for-gestational age indicate a perinatal vulnerability for SDH beyond 1st week of life. The association between prematurity/small-for-gestational age and abuse diagnosis is intriguing and not easily understood.
