Abstract
INTRODUCTION: As hospitals strive to reduce their environmental footprint, there is an ongoing debate over the environmental implications of reusable versus disposable linens in operating rooms (ORs). This research aimed to compare the environmental impact of reusable versus single-use OR bed covers and lift sheets using life cycle assessment (LCA) methodology. METHODS: LCA is an established tool with rigorous methodology that uses science-based processes to measure environmental impact. This study compared the impacts of three independent system scenarios at a single large academic hospital: reusable bed covers with 50 laundry cycles and subsequent landfill disposal (System 1), single-use bed covers with waste landfill disposal (System 2), and single-use bed covers with waste disposal using incineration (System 3). RESULTS: -eq. The raw material extraction for all the material to produce an equivalent 50 single-use OR bed cover kits was tenfold more carbon-intensive than the reusable bed cover. Laundering one reusable OR bed cover 50 times was more carbon intensive (12.12 kg CO2-eq) than landfill disposal of 50 single-use OR bed covers (2.52 kg CO2-eq). DISCUSSION: Our analysis demonstrates that one reusable fabric-based OR bed cover laundered 50 times, despite the carbon and water-intensive laundering process, exhibits a markedly lower carbon footprint than its single-use counterparts. The net difference is 45.16 kg CO2-eq, equivalent to driving 115 miles in an average gasoline-powered passenger vehicle. This stark contrast underscores the efficacy of adopting reusable solutions to mitigate environmental impact within healthcare facilities.
