Abstract
Introduction
Infections caused by multidrug-resistant gram-negative bacilli (MDR-GNB) in critically ill patients present a challenge for timely and appropriate antibiotic treatment. This is particularly important in patients undergoing extracorporeal life-support techniques such as renal replacement therapy and extracorporeal membrane oxygenation. These techniques can introduce additional pharmacokinetic alterations, potentially leading to suboptimal exposure to antibiotics. This study aims to outline dosing strategies and therapeutic drug monitoring protocols for new β-lactam antibiotics effective against MDR-GNB in critically ill patients undergoing extracorporeal life-support techniques at a national level. Additionally, the study seeks to develop a consensus document, based on available evidence.
Methods
The project will comprise two main phases: I) a national survey and II) the development of a consensus document. This consensus document, undertaken according to ACCORD guidelines, will encompass: a) establishment of a multidisciplinary panel of experts, b) prospective registration of the consensus, c) evidence synthesis, d) modified Delphi rounds. The antimicrobials to be included will be: meropenem, ceftazidime/avibactam, ceftolozane/tazobactam, cefiderocol, meropenem/vaborbactam, imipenem/relebactam, and aztreonam. Extracorporeal life-support techniques will include continuous renal replacement therapy, conventional intermittent hemodialysis, and extracorporeal membrane oxygenation.
Discussion
The availability of extracorporeal life-support techniques has expanded significantly in recent years, alongside a rise in the prevalence of infections caused by MDR-GNB. There is a need to develop evidence-based tools of high quality to standardize dosing and monitoring strategies for new β-lactam antibiotics.
