Toh S, Ong C, Sultana R, et al. - In this systematic review and meta-analysis, researchers sought to summarize the overall impact of pediatric intensive care unit (PICU) admission body mass index (BMI) on clinical outcomes. The following medical databases were searched from inception through May 2020: PubMed, Excerpta Medica database, Cumulative Index of Nursing and Allied Health Literature, Cochrane Library, and Web of Science. Participants in the study were 21,558 patients. The systematic review did not show any link between PICU admission BMI status and outcomes in critically ill children. To clarify the relationship between nutritional status and clinical outcomes of PICU patients, more research with standardized nutrition status classification on admission, stratified by patient subgroups, is needed.
