Impact of socio-behavioral measures implemented during the SARS-CoV-2 pandemic on the outcomes of febrile neutropenia episodes in pediatric cancer patients: a single center quasi-experimental pre-post study.

During COVID-19, public health measures including masks and social distancing decreased viral upper respiratory infections (URI). Upper respiratory infections are the most common infectious etiology for low-risk pediatric febrile neutropenia (FN). This single-center, quasi-experimental, pre-post study was designed to understand the impact of public health measures on FN admissions and outcomes in the general pediatric oncology population during the COVID (March 2020-February 2021) vs. pre-COVID era (January 2018-February 2020) and their respective respiratory seasons (November-February). Episodes were risk-stratified using a tool recommended by the Children's Oncology Group. Descriptive and bivariate statistics were used to compare admission characteristics and outcomes. Comparing respiratory seasons, the Covid-era season had 60% fewer URI diagnoses (5/12), while high-risk episodes (63.6% [28/44] vs. 44.2% [23/52]) and intensive care admissions (18.2% [8/44] vs. 3.8% [2/52]) increased. Between eras, URIs were lower in the COVID-era (10.8% [16/148] vs. 19.9% [67/336]; p = 0.01), but admission characteristics and severe outcomes were not different. The impact of public health measures was most prominent during the respiratory season. Despite decreased incidence of URIs, the overall admission characteristics and severe outcomes were minimally impacted due to the brevity of respiratory seasons, but larger studies are warranted.
