Characterization of Febrile Neutropenia in Pediatric Patients With Cancer Before and After Implementation of Coronavirus Disease 2019 Precautions.

Historically, febrile neutropenia (FN) has constituted a common but life-threatening emergency in pediatric oncology patients. As such, hygiene precautions have consistently been recommended for immunosuppressed patients. These precautions, however, were more strictly and widely adopted during the coronavirus disease 2019 pandemic. Universal mask mandates, emphasis on hand hygiene, and encouragement of social distancing were some of the many initiatives introduced in an effort to reduce transmission of the virus. There is little data available regarding whether the universal adoption of these precautions was associated with any changes in the incidence of hospitalizations for FN in pediatric oncology patients. A retrospective chart review was utilized to evaluate newly diagnosed patients admitted for FN in the first 14 months of the pandemic compared with the same time period during the previous year. During the pandemic, the admission rate for FN was 28.9%, compared with 29.1% prepandemic ( P = 0.97). There was no significant difference in causative organisms when comparing time periods. In addition, the presence of a state government-enforced mask mandate was associated with an increased admission rate for FN during the pandemic period.

Evaluation of Possible Effects of the COVID-19 Pandemic on Febrile Neutropenia Episodes in Children With Acute Leukemia.

With the rapid spread of coronavirus disease 2019 (COVID-19) around the globe, concerns about the management of patients with malignancy have risen significantly. This study aimed to investigate the possible impact of the COVID-19 pandemic and prevention policies on the incidence and etiology of febrile neutropenia (FN) episodes in children with acute leukemia. Children who had acute leukemia and were diagnosed as FN in a tertiary center from March 2018 to March 2021 were included in the study. FN episodes were grouped as prepandemic and postpandemic based on the date that pandemic was declared. Relevant data were collected retrospectively. We evaluated 113 FN episodes (75.2% were prepandemic) of 46 patients, a median of 4.7 (2.6 to 12.6) years of age. The number of FN episodes per patient did not differ between prepandemic and postpandemic periods ( P =0.476). There was no significant difference among the 2 groups regarding the microbiologic causes, focus of fever, and clinical outcomes in FN episodes. Two of the patients were diagnosed as COVID-19 and recovered without any complications. In conclusion, we showed that the incidence and etiology of FN episodes were similar before and during the COVID-19 pandemic in children with acute leukemia.
