Insights
Paediatric emergency room (ER) visits significantly decreased during COVID-19 restrictions, but children presenting were not more severely ill. These findings suggest no immediate negative health impacts from pandemic control measures on children.
Area of Science:
- Pediatrics
- Public Health
- Epidemiology
Background:
- COVID-19 pandemic restrictions led to significant societal changes.
- Understanding the impact of these restrictions on child health is crucial.
Purpose of the Study:
- To evaluate the immediate health effects of COVID-19 pandemic restrictions on children.
- To analyze trends in paediatric emergency room (ER) visits during the pandemic.
Main Methods:
- Retrospective examination of paediatric ER visits at Helsinki University Hospital.
- Comparison of visits during the first COVID-19 wave (March-May 2020) with pre-pandemic and post-pandemic periods (2015-2019 reference).
Main Results:
- Total paediatric ER visits decreased by 23.4% during the pandemic period.
- Decreases were primarily due to fewer infectious disease-related visits; surgical visits remained stable.
- The severity of illness among children visiting the ER did not increase, and visits returned to baseline post-restrictions.
Conclusions:
- Paediatric ER visits decreased during COVID-19 restrictions.
- Children seeking emergency care were not more severely ill during this period.
- The study indicates no immediate detrimental health effects of pandemic control measures on children.
Aim:
To investigate paediatric emergency room (ER) visits to evaluate the immediate health effects of COVID-19 pandemic restrictions on children.
Methods:
We retrospectively examined paediatric ER visits in the Helsinki University Hospital (HUH) district during the first wave of the pandemic (1 March to 31 May 2020), and a 2-month period immediately before and after. These periods were compared to the corresponding time periods in 2015-2019 ('reference period').
Results:
The total number of ER visits decreased by 23.4% (mean 6474 during the reference period, 4960 during the pandemic period (incidence rate ratio [IRR] 0.75, 95% confidence interval 0.72-0.77; p < 0.001). This was due to a decrease in visits related to infectious diseases; visits due to surgical reasons did not decrease. The amount or proportion of patients triaged to the most urgent class (Emergency Severity Index 1) did not increase. Paediatric ER visits returned to baseline after lifting of restrictions.
Conclusions:
Although paediatric ER visits substantially decreased during the pandemic restrictions, children seen at the ER were not more severely ill. Our results do not indicate immediate detrimental health effects of pandemic control measures on children.
