A comparative life cycle assessment of the environmental impact of preoperative skin preparation, single-use applicators versus bulk antiseptic with reusable instruments.

Background: Preoperative skin preparation (PSP) is a critical step of surgery to reduce bacteria on the skin that can cause infections. It is commonly believed that the reusable equipment method of PSP reduces environmental emissions relative to single-use options. However, no research comparing entire-life cycle environmental emissions associated with the two approaches exists. Methods: A Life Cycle Assessment (LCA) was conducted comparing PSP in a European hospital using a single-use applicator versus a reusable equipment method. Results: Findings highlight the superior environmental performance of a single-use antiseptic applicator method, resulting in 49% less CO Discussion: The study challenges the assumption that reusable systems always result in lower environmental impacts. This LCA revealed that efficient manufacturing processes, optimized use of antiseptic during procedure, and reduced energy consumption throughout the single-use method life cycle can decrease the carbon footprint. This highlights the need to scrutinize the life cycle when making comparisons as part of surgical sustainability.
