Background The aim of this study is to compare the 2021–2022 bronchiolitis season to the four previous years (2017–2018, 2018–2019, 2019–2020, 2020–2021) to see if there was an anticipation of the peak, an overall increase of cases, and an increased need of intensive care. Methods A retrospective single-centre study in the San Gerardo Hospital Fondazione MBBM, Monza, Italy was performed. Emergency Departments (ED) visits of patients aged < 18 years and ≤ 12 months were analyzed: the incidence of bronchiolitis on total assessments, the urgency level at triage and the hospitalization rate were compared. Data of children admitted to the Pediatric Department due to bronchiolitis were analyzed in terms of need of intensive care, respiratory support (type and duration), length of hospital stay, main etiological agent, patient characteristics. Results During 2020–2021 (first pandemic period) an important reduction in the ED attendance for bronchiolitis was observed, while in 2021–2022 there was an increase in incidence of bronchiolitis (13% of visits in infants < 1 year) and in the rate of urgent accesses (p = 0.0002), but hospitalization rates did not differ compared to previous years. Furthermore, an anticipated peak in November 2021 was observed. In the 2021–2022 cohort of admitted children to the Pediatric Department, a statistically significative increased need of intensive care unit was detected (Odds Ratio 3.1, 95% CI 1.4–6.8 after adjustment for severity and clinical characteristics). Instead, respiratory support (type and duration) and length of hospital stay did not differ. RSV was the main etiological agent and RSV-bronchiolitis determined a more severe infection (type and duration of breathing support, intensive care need and length of hospital stay). Conclusions During Sars-CoV-2 lockdowns (2020–2021), there was a dramatic decrease of bronchiolitis and others respiratory infections. In the following season, 2021–2022, an overall increase of cases with an anticipated peak was observed and data analysis confirmed that patients in 2021–2022 required more intensive care than children in the four previous seasons.

“…30 However, a considerable increase in RSV infections has been described in 2021 and fall of 2022. 11,12 Since there are different theories proposed for this increase in cases, it seems logical to think that in the coming months and years, we will witness a new upturn in publications related to infantile bronchiolitis, trying to find plausible explanations for this upturn in cases.…”

Background The COVID‐19 pandemic has led to a significant increase in cases of bronchiolitis among children. As a result, there has been a corresponding increase in the number of publications on this topic. It is essential to examine the main areas of focus within the scientific literature to understand the current trends in research on pediatric bronchiolitis. This research aims to analyze the types of scientific advances related to pediatric bronchiolitis, the research trends being pursued, and the countries and research institutions leading these efforts. By understanding these aspects of bronchiolitis research, we can better understand the current state of knowledge and identify areas where further research is needed. Methods To conduct a bibliometric analysis of the scientific literature on pediatric bronchiolitis, all relevant publications were retrieved from the Scopus database. The Scopus API and the SW VosViewer software with optimized modularity functions were used. This analysis was intended to provide a comprehensive overview of the current state of research on this topic, including the types of scientific advances being developed, the research trends being pursued, and the countries and research institutions leading these efforts. Results A total of 3810 publications were reviewed. We observed an increasing number of publications, particularly in recent years. Of these, 73.7% were articles, 95% were written in English, and 29.4% were from the United States. The main keywords used in these publications included: human, bronchiolitis, child, preschool, preschool child, major clinical study, controlled study, pneumonia, asthma, adolescent, hospitalization, infant, and newborn. These keywords were grouped into six clusters: outpatient management, long‐term consequences, etiology, intensive care management, diagnostic methods, and the main cluster, which focused on hospital treatment and clinical studies. Conclusions The bibliometric analysis of bronchiolitis research in pediatrics reveals that there has been a significant increase in the number of publications on this topic, particularly in recent years. Most of these publications are articles written in English and published in the United States. The main keywords used in these studies relate to various aspects of bronchiolitis, including diagnosis, treatment, and long‐term consequences. The results of this analysis suggest that bronchiolitis is a topic of significant interest and concern for researchers and practitioners in the field of pediatrics and that further research is needed to improve our understanding and management of this condition.

IntroductionDuring the COVID‐19 pandemic, pediatric visits due to acute lower respiratory infections (ALRIs) decreased, but most reports are from hospitalized patients. There is little information on this phenomenon in outpatients, who are the majority in ALRI. We evaluated the impact of the COVID‐19 pandemic on ALRI‐related outpatient visits in the City of Buenos Aires.MethodsObservational study including all outpatient visits of children under 2 years of age to the public health system of the City of Buenos Aires, between 1 January 2018 and 31 December 2022. We analyzed the total number of visits and the ALRI‐related visits, and their distribution throughout the study period.ResultsA total of 704,426 visits were registered, 7.38% of them due to ALRI. ALRI‐related visits decreased from the implementation of a national lockdown (2020) and increased again as the restriction measures decreased, particularly the return to full school attendance (2021). In general, the proportion of ALRI‐related visits was significantly higher in the cold months than in the warm ones (9.8% vs. 5.5%; odds ratio: 1.76, 95% confidence interval: 1.73–1.79; p < .001). This difference was observed before (2018 and 2019) and after the pandemic (2022), but not in 2020–2021. The peak of ALRI‐related visits occurred in the cold months in pre‐pandemic years (2018–2019), did not appear in 2020, reappeared delayed in 2021, and recovered seasonality in 2022.ConclusionOutpatient ALRI‐related visits decreased significantly in the city of Buenos Aires during the COVID‐19 pandemic and currently seem to have recovered their magnitude and seasonality.
