The Challenge of Identifying Pediatric Abusive Head Trauma During the COVID-19 Pandemic

Hospital Admissions for Abusive Head Trauma Before and During the COVID-19 Pandemic

Importance

Several studies have demonstrated a decrease in the occurrence of child abuse in the US since the start of the COVID-19 pandemic. This finding has generated concern for missed cases due to the initial lockdowns and lack of childcare resources. Determining the association of the pandemic on hospitalizations for severe forms of abuse is essential to focus preventive efforts.

Objective

To examine trends in abusive head trauma (AHT) before and during the COVID-19 pandemic.

Design, Setting, and Participants

Retrospective, multicenter, repeated cross-sectional study, conducted January 1, 2016, through April 30, 2022, with data from tertiary care children's hospitals and contributors to the Pediatric Health Information System. Data were obtained for 2380 hospitalizations of children younger than 5 years with International Classification of Diseases, Tenth Revision, Clinical Modification codes for both abuse and head trauma.

Main Outcomes and Measures

Monthly hospitalizations were analyzed using interrupted time-series analysis. Hospitalization severity (eg, intensive care unit stay) and clinical characteristics (subdural hemorrhages and retinal hemorrhages) were compared before and after the start of the pandemic.

Results

We identified 2380 hospitalizations due to AHT (median age, 140 [IQR, 75.0-325.5] days) from 45 hospitals. The mean (SD) monthly incidence of AHT was 34.3 (5.8) before the COVID-19 pandemic compared with 25.6 (4.2) during COVID-19 (a 25.4% decrease). When the pre-COVID-19 and during COVID-19 periods were compared, there were no significant differences in severity or clinical characteristics. On interrupted time-series analysis, there was a significant decrease in the number of monthly hospitalizations (-8.1; 95% CI, -12.41 to -3.72; P < .001) in the first month of the pandemic. In the subgroup of children younger than 1 year, there was a significant decrease in monthly hospitalizations at the onset of the pandemic (-8.2; 95% CI, -12.02 to -4.43; P < .001) followed by a significant temporal increase across the COVID-19 period (P = .01).

Conclusions and Relevance

The findings of this cross-sectional study suggest there was a significant decrease in monthly hospitalizations for AHT following the start of the pandemic in March 2020. Although there was no corresponding increase in hospitalization severity, the decrease during the pandemic may have been transient, as monthly hospitalizations for children younger than 1 year increased significantly over time during COVID-19, after the initial decrease.

Effect of the COVID-19 Pandemic on the Epidemiology of Pediatric Traumatic Brain Injury in Brazil

Aim In response to the coronavirus 2019 disease (COVID-19) pandemic, governments worldwide implemented measures to prevent infection, resulting in restricted school activities, restricted children's freedom of movement, and increased risk of violence and injuries at home, including traumatic brain injury (TBI), among children. In Brazil, the consequences of the COVID-19 pandemic on the causes, severity, and mortality of pediatric TBI have not yet been investigated. Thus, our study aimed to determine whether the COVID-19 pandemic has affected the epidemiology of pediatric TBI among Brazilian children. Materials and methods We investigated the patients with TBI aged <18 years who visited a tertiary trauma center in Brazil in 2019 and 2020. TBI-related variables, such as classification, mechanism, clinical manifestations, need for intervention, morbidity, and mortality, were recorded. Furthermore, we used a nationwide databank to collect information on mortality from external causes of trauma and violence in the pediatric population in 2019 and 2020. The Mann-Whitney test was used to compare quantitative variables related to the mechanisms and severity of TBI in both periods in order to determine the impact of the COVID-19 pandemic. Results Of the patients with traumatic brain injury, 1371 visited the trauma center in 2019 and 1052 in 2020. No difference was noted in the incidence rate of abusive head trauma between these periods (p=0.142) or in mortality from violence in Brazil. Recreational causes of pediatric TBI increased during the first year of the COVID-19 pandemic in Brazil and falls from bicycles significantly increased during the pandemic (p<0.001). Conclusion A global reduction in pediatric admissions to emergency rooms as well as no impact on mortality and severity of pediatric TBI were observed during the COVID-19 pandemic in Brazil. Additionally, a public education program regarding child safety during recreational activities, particularly how to avoid falls from bicycles was recommended.

Incidence of child abuse with subdural hemorrhage during the first year of the COVID-19 pandemic: a nationwide study in France

The global COVID-19 pandemic prompted governments to impose unprecedented sanitary measures, such as social distancing, curfews, and lockdowns. In France and other countries, the first COVID-19 lockdown raised concerns about an increased risk of child abuse. Abusive head trauma (AHT) is one of the most serious forms of child abuse in children aged 0-24 months and constitutes the leading cause of death in children under 2 years of age. Subdural hemorrhage (SDH) is present in 89% of cases of AHT and constitutes one of the most specific, objective clinical presentations in the diagnosis of child abuse. In a French nationwide study, we sought to evaluate the potential impact of the first year of the COVID-19 pandemic on the incidence of hospital admissions for child abuse with SDH, relative to the two previous years. We conducted a nationwide, retrospective study of data in the French national hospital discharge summary database by applying the International Classification of Diseases (10th Revision) codes for SDH and for child abuse. After including children aged up to 24 months with a diagnosis of child abuse and/or SDH following hospital admission anywhere in France between January 1, 2018, and December 31, 2020, we compared the incidence of child abuse, the incidence of SDH + child abuse, and the demographic data for 2020 with the corresponding values for 2018 and 2019. There were no significant differences in the number of hospital admissions due to child abuse or SDH + child abuse between 2020 and the 2018/2019 control years. The incidence of SDH + child abuse was higher among boys than among girls. There were significantly fewer hospital admissions in May 2020 (p = 0.01) and significantly more in December 2020 (p = 0.03), relative to the same months in the two preceding years. There was a nonsignificant trend toward a lower incidence of hospital admission for child abuse in 2020, relative to 2019 (decrease: 6.4%) and 2018 (decrease: 7.6%).

CONCLUSION

When considering children under the age of 24 months in France, the incidence of hospital admission for SDH in the context of child abuse was not significantly higher in 2020 than in the two previous years.

WHAT IS KNOWN

• The impact of COVID-19 lockdown on child abuse and more specifically on subdural hemorrhage remains unknown.

WHAT IS NEW

• There was no increase in hospitalizations for child abuse and AHT. • We found that boys are more often victims of child abuse and subdural hemorrhage among children aged less than 12 months.
