Impact of the SARS-CoV-2 pandemic and associated restrictions on Pediatric Emergency Department utilization in Sardinia: a retrospective bicentric observational study

BACKGROUND: The COVID-19 pandemic and associated public health measures have had a profound impact on health systems worldwide. The aim of this study was to assess quantitative and qualitative changes in Pediatric Emergency Department (PED) visits in Sardinia, Italy, during the early period of the COVID-19 pandemic. METHODS: We retrospectively investigated the number and characteristics of visits to two major Sardinian PEDs, in the periods January-June 2020 and January-June 2019. RESULTS: From January to June 2020, 8399 PED visits with 1160 hospital admissions (13.8% of PED visits) were registered, compared with 15,692 PED visits (Δ = -46.5%) and 1819 hospital admissions (11.6% of PED visits) occurring from January to June 2019. Comparing January-June 2020 with January-June 2019, we found differences in the percentage of visits for age groups, and significant changes in the proportion of triage codes, with a decrease in green codes (72.1% vs 74.2%, respectively) and an increase in white codes (19.0% vs 16.5%, respectively). Moreover, in the period January-June 2020, the frequency of skin disorders and acute respiratory disease significantly decreased, while the frequency of trauma, acute surgical disease, intoxication, and neuropsychiatric disease significantly increased. CONCLUSIONS: After the beginning of the Italian lockdown, we observed a marked drop in the number of PED visits, an increase in hospital admission rate, and radical changes in the reason for visit.
