Covid lockdowns and hospitalisations for oro-facial trauma among children in Australia and the United Kingdom.

BACKGROUND/AIM: This retrospective study investigated the effect of lockdowns for Covid-19 on the rates of oro-facial trauma hospitalisations in children in Australia and the United Kingdom (UK). MATERIALS AND METHODS: Hospitalisation data for children up to 19 years old for oro-facial trauma injuries (according to ICD-10-AM principal diagnosis codes) over 5 years were collected for Australian and UK children. The age-standard rate (ASR) for each age group was calculated per 100,000 population. RESULTS: In the younger Australian children, there was no statistically significant change in the ASR of oro-facial trauma hospitalisations during the 'Covid year', compared to the average rate over the 3 years preceding. However, there was a significant decrease in the ASR of oro-facial trauma hospitalisations during the 'Covid year' in older Australian children (aged 10-19), and for all UK children, except for infants under one-year-old. CONCLUSIONS: Reduction of the ASR of hospitalisations due to oro-facial trauma during the 'Covid year', and the implementation of lockdown measures in the two countries provides further evidence of the impact of physical activities and travel as contributing factors to oro-facial injuries in children. In addition to its role in reducing the spread of virus infections during the pandemic, the lockdown measures also resulted in a simultaneous decrease in trauma injuries.

Effects of the Child Dental Benefits Schedule on dental hospitalisation rates in Australian children.

Objective The Child Dental Benefits Schedule (CDBS) was introduced in 2014, and its aim was to support access to dental care for eligible children in Australia. Dental caries, and pulp and periapical diseases were the major dental reasons for children's hospitalisations. This study investigated if the availability of the CDBS had any effects on hospitalisation rates in Australian children. Methods This study was a retrospective analysis of Medicare data from the Australian Government and the hospitalisation data from The Australian Institute of Health and Welfare (AIHW) from 2008 (6 years before the commencement of the CDBS) to 2020 (6 years after the commencement of the CDBS). Results Although the hospitalisation rate trend was reducing before the CDBS started (2008-14), this reduction was not statistically significant. The reduction of hospitalisation rates was higher after the commencement of the CDBS (2014-20) and was statistically significant, but the regression model analysis showed a positive correlation between the CDBS and hospitalisation rate. The analysis without 'abnormal' year data (2019-20, COVID-19 pandemic year) supported no statistically significant decrease in hospitalisation rate after the commencement of the CDBS in 2014 until 2019. Conclusion Although the CDBS is improving access to dental care for eligible children, any possible effects the CDBS might have on hospitalisations are not yet evident.

Association between Western Australian children’s unplanned dental presentations and the socioeconomic status of their residential area.

Objective This study investigated the link between socioeconomic status and unplanned dental presentations at the Perth Children's Hospital (PCH), as well as the link between the socioeconomic status of unplanned dental patients and any previous admissions to the PCH. Methods Records of 351 unplanned visits to the PCH were collected, including reason for attendance (infection, trauma, other), the patient's residential location (suburb) and the history of any previous presentations at the PCH. The socioeconomic status of each patient was based on the Index of Relative Socio-Economic Disadvantage, divided into quintiles. Geographic information systems (GIS) were used to spatially map the residential locations of the patients with unplanned dental presentations. QGIS was used to map and geocode the data. Analysis of variance and Chi-squared tests were used to determine associations between subgroups and other variables. Results 'Unplanned dental presentation' in this study refers to patients who present without an appointment, including by referral from the emergency department of the PCH or outside the PCH. Approximately two-thirds of unplanned dental presentation among patients from low socioeconomic groups were for dental infection, whereas the major reason for presentation among patients from higher socioeconomic groups was trauma. More than half the patients in low socioeconomic groups had at least one previous presentation at the PCH due to other medical issues. Conclusion Children from low socioeconomic groups, or from outside of Perth, were more likely to present with dental infections, which are mostly preventable at the primary care level; these patients often presented a more significant burden to the health system. Public health interventions should aim to promote preventive oral health care, especially for children from low socioeconomic groups. What is known about the topic? In Western Australia, the most common dental problems requiring hospitalisation among children is dental caries, and children from the lowest socioeconomic backgrounds have the highest prevalence of dental hospitalisations. What does this paper add? Children from lower socioeconomic backgrounds were more likely to have an unplanned presentation at the only tertiary children's hospital in Western Australia due to dental infection. What are the implications for practitioners? Improved access to public dental services, especially in low socioeconomic areas, and the development of more strategies to reduce unplanned dental presentations at a tertiary hospital are needed.
