Operating Room Waste Reduction

Abstract

One-fourth of all operating room (OR) waste is attributed to anesthesia-related material. The goal of this project was to reduce the waste and increase cost savings of opened and unused endotracheal (ET) tubes and disposable laryngoscope handles and blades in 2 separate OR environments. The production of these unused anesthesia supplies was assessed weekly in each of 2 OR environments for 8 weeks before an educational intervention, and for 8 weeks following the intervention. The average weekly waste production was summarized for each study period, compared between periods (preintervention vs postintervention), and analyzed per 100 surgeries using the 2-sample t test. The overall average weekly waste for ET tubes was significantly reduced from 26.7 ± 10.7 to 10.0 ± 6.1 from pre to post intervention (P = < .001), representing a 62.6% reduction. A similar significant reduction in waste was observed for laryngoscope handles (15.9 ± 8.1 vs 7.2 ± 3.1; P = .004; a 54.7% reduction) and laryngoscope blades (21.5 ± 11.0 vs 9.9 ± 4.4; P = .004; a 54.0% reduction). These results highlight the significance and feasibility of an educational intervention in reducing the environmental and economic waste produced by anesthetic practices in the OR.
