Abstract

Importance  Important advances have been made in extracorporeal blood purification therapies (EBPTs) due to new technologies and biomaterials; however, the lack of established guidelines is a factor in great variability in clinical practice. This aspect is accentuated in pediatric intensive care given the small number of patients with diverse diagnoses treated with EBPT and the technical challenges in treating small children, potentiating the risk of adverse events.

Objective  To understand what experienced users of EBPT think about its relevant issues, insight that may have implications for the design of future studies, and the application of EBPTs in patient care.

Evidence Review  Literature search was conducted using the PubMed and Embase databases between January 1, 2020, and July 15, 2024, and a combination of key medical terms. A panel of experts was formed (composed of 15 authors and pediatric intensivists) to develop a consensus statement using a modified Delphi-based model between 2022 and 2024. The panel’s core team drafted the initial questionnaire, which explored EBPT use in pediatric intensive care units (PICUs), including clinical indications for initiating and discontinuing use and outcomes for assessing effectiveness and safety. SurveyMonkey was used in the distribution, completion, and revision of the questionnaire, and findings were analyzed. Panelists were asked to rank answer choices. Numerical value for each ranking was translated to a percentage defining the strength of consensus (>90% agreement from panelists signifying strong consensus; <49% signifying no consensus).

Findings  A total of 116 survey responses were received from panelists from 8 European countries. Strong consensus was achieved on 6 of 24 questions and consensus (75%-90% agreement) was reached on 18 of 24 questions. According to the panelists, the continuous renal replacement therapy standard or enhanced adsorption hemofilter and plasma exchange were of interest, representing the most applied EBPTs across various applications. While evidence on hemoadsorption is growing, it remains limited.

Conclusions and Relevance  This consensus statement on EBPTs in critically ill pediatric patients was developed by an international panel of experts in areas where clinical evidence is still limited. This consensus statement could support pediatric intensivists in bedside decision-making and guide future research on EBPTs in PICUs.
