Antibiotic Stability in Portable Elastomeric Infusion Devices: A Systematic Review

Purpose: Although outpatient parenteral antibiotic therapy (OPAT) can be a good approach to treatment of infections, a lack of data regarding antibiotic stability in portable elastomeric infusion devices restricts its safe, appropriate, and effective use. The objective of this work was to complete a systematic peer-reviewed analysis of published articles about antibiotic stability in elastomeric infusion devices that provide evidence supporting their use in OPAT.

Summary: A systematic review following PRISMA guidelines was conducted in January 2021 to identify published articles about antibiotic stability in portable elastomeric infusion devices. The databases used were PubMed, Embase, Web of Science, and a Cochrane database. A total of 1,615 original studies and conference communications were found. After title, abstract, and full-text review, 33 articles met the inclusion criteria. The data obtained included information about the stability of 30 different antibiotics. To our knowledge, this is the first review to summarize the available published data on the stability of antibiotics in portable elastomeric infusion devices. The results highlight the poor stability of some antibiotics in solution and the variability of the laboratory conditions in the included studies.

Conclusion: This systematic review can serve as a useful resource for healthcare professionals involved in providing OPAT using portable elastomeric infusion devices. However, further stability studies should be performed, especially high-quality studies simulating real-life time and temperature conditions.
