Aim: The research aim was to conduct a systematic review of the literature regarding the pharmacokinetics (PK) and dosing of antimicrobials in prolonged intermittent renal replacement therapy (PIRRT), a hybrid form of dialysis becoming increasingly utilised in critical care. Methods: A literature review was performed using PubMed from database inception to October 2020 according to the PRISMA guidelines. All papers published in English language were included in the review. Two researchers

The types of papers retrieved varied between case reports, single and multiple dose pharmacokinetic studies and Monte Carlo simulations. Results: A total of 149 articles were found in the initial literature review and via other sources. Of these papers, 50 articles were deemed eligible for inclusion. These studies included one to 34 patients. PIRRT settings varied between institutions, including filter surface area, duration of PIRRT and type of dialyser used. With the exception of vancomycin and meropenem, few antimicrobials had sufficient data available from which reasonable empiric dosing regimens can be recommended. Conclusion: There is limited data to guide dosing of antimicrobials during PIRRT. More studies are required to understand how dosing can be optimised in this population of critically ill patients. The authors declare that they have no conflict of interest. REFERENCES 1 Brown P, Battistella M.
