ABSTRACT
BACKGROUND AND AIM: Bronchiolitis is the most common lower respiratory illness in young children, mostly caused by Respiratory Syncitial Virus (RSV);PICU admission for respiratory support is required in some cases. The recent Covid-19 pandemic has altered dynamics of viral transmission in the community. We aim to describe if there has been a modification in the number and characteristics of patients admitted to Italian PICUs between the pre-pandemic and post-pandemic period. METHOD(S): Multicenter retrospective observational study based on the national electronic web-based national registry of the Italian Network of PICU Study Group (TIPNet). PICU admissions due to bronchiolitis were compared from 2017 to 2022, considering the seasonal peak periods (October, 1st to April, 30th). RESULT(S): 918 patients have been admitted due to bronchiolitis to Italian PICUs in the above mentioned years. Cumulative yearly admissions are reported in Figure 1. The winter season of 2020-2021 reported a significantly lower number of admissions. RSV was consistently the reported cause in most cases throughout the years except in season 2020-2021, when it was never reported. In the 2020-2021 season, enterovirus was reported in 23% of cases. Covid-19 as cause of bronchiolitis was reported in one case in 2020- 21 and 2 cases in 2021-22. CONCLUSION(S): Covid-19 pandemic, due to possibly multiple factors, has changed the panorama of PICU admissions due to bronchiolitis in Italy. Although research is still ongoing, it seems that Covid itself is not a cause of severe bronchiolitis requiring respiratory support. (Figure Presented).
ABSTRACT
The COVID-19 pandemic is affecting healthcare services worldwide. We investigated the impact of a strict lockdown policy on the characteristics of neonatal and pediatric attendances to our pediatric emergency department (PED). The clinical features of PED visits in March-April 2020 (COVID-19) and March-April 2019 (non-COVID-19) were analyzed. During the COVID-19 lockdown period, visits reduced by 67%, from 3159 to 1039. Neonatal access decreased from 78 to 59, mainly due to fewer pathological conditions, with a complete disappearance of respiratory infections. On the other hand, minor neonatal clinical conditions rose from 44 (56.4%) to 48 (81.4%), mostly due to feeding-related issues. Communicable diseases, particularly respiratory infections and gastroenteritis, dropped from 1552 (49.1%) to 288 (27.7%). Accident-related visits also decreased during COVID-19, from 535 (16.9%) to 309 (29.7%), becoming the most common cause of PED access. Hospital admissions reduced from 266 to 109, while PICU (pediatric intensive care unit) admissions decreased from 27 to 11, with a comparable rate of 10.1% in both periods. The lockdown due to COVID-19 had a substantial impact on our PED visits, which markedly decreased, mainly due to fewer respiratory infections. Unexpectedly, neonatal visits for minor conditions did not decline, but rather slightly increased. Among the children admitted to the PICU, none had respiratory disease.
