Coagulation Dysfunction Criteria in Critically Ill Children: The PODIUM Consensus Conference

CONTEXT Previous criteria for coagulation dysfunction in critically ill children were based mainly on expert opinion. OBJECTIVE To evaluate current evidence regarding coagulation tests associated with adverse outcomes in children to inform criteria for coagulation dysfunction during critical illness. DATA SOURCES Electronic searches of PubMed and Embase were conducted from January 1992 to January 2020 by using a combination of medical subject heading terms and text words to define concepts of coagulation dysfunction, pediatric critical illness, and outcomes of interest. STUDY SELECTION Studies were included if critically ill children with coagulation dysfunction were evaluated, if performance characteristics of assessment and/or scoring tools to screen for coagulation dysfunction were evaluated, and if outcomes related to mortality or functional status, organ-specific outcomes, or other patient-centered outcomes were assessed. DATA EXTRACTION Data were abstracted from each eligible study into a standard data extraction form, along with risk of bias assessment, by a task force member. RESULTS The systematic review supports the presence of at least 2 of the following criteria reflecting coagulation dysfunction in the absence of liver dysfunction: platelet count 1.5, fibrinogen level LIMITATIONS The proposed criteria for coagulation dysfunction are limited by the available evidence and will require future validation. CONCLUSIONS Validation of the proposed criteria and identified scientific priorities will enhance our understanding of coagulation dysfunction in critically ill children.
