Abstract

Healthcare sustainability is a multidisciplinary field that seeks to mitigate healthcare's environmental consequences. Antimicrobial stewardship and healthcare sustainability both aim to reduce wasteful resource use while maximizing patient safety. However, a strong partnership between antimicrobial stewardship and healthcare sustainability has yet to develop. To facilitate environmentally sustainable decision-making in antimicrobial prescribing, we developed a web-based calculator (EcoRxChoice (www.ecorxchoice.com)) where users can enter different antimicrobial regimens and compare how much plastic waste each regimen creates. This work was supported in part by the Society of Infectious Diseases Pharmacists (SIDP), reflecting SIDP's commitment to strengthening sustainability as a practical extension of antimicrobial stewardship and empowering infectious disease pharmacists to make measurable environmental impact through evidence-based care.
