OBJECTIVE: To quantify the environmental impact of standard direct laryngoscopy surgery and model the environmental benefit of three feasible alternative scenarios that meet safe decontamination reprocessing requirements.
STUDY DESIGN: This is a life cycle assessment (LCA) modeling study.
SETTING: Yale-New Haven Hospital (YNHH), a 1541-bed tertiary medical center in New Haven, Connecticut, USA.
METHODS: We performed cradle-to-grave LCA of DLS at Yale New Haven Hospital in 2022, including global warming potential (GWP), water consumption, and fine particulate matter formation. Three alternative scenarios were modeled: disinfecting surgical tools using high-level disinfection rather than steam sterilization, substituting non-sterile for sterile gloves and gowns; and reducing surgical towel and drape sizes by 30%.
RESULTS: Changes in disinfection practices would decrease procedure GWP by 11% in each environmental impact category. Substituting non-sterile gowns and gloves reduced GWP by 15%, with nominal changes to water consumption. Linen size reduction resulted in 28% less procedure-related water consumption. Together, a nearly 30% reduction across all environmental impact categories could be achieved.
CONCLUSIONS: Not exceeding minimum Center for Disease Control (CDC) decontamination standards for reusable devices and optimizing non-sterile consumable materials could dramatically reduce healthcare-associated emissions without compromising safety, thereby minimizing the negative consequences of hospital operations to environmental and human health. Findings extend to other non-sterile surgical procedures.
LEVEL OF EVIDENCE: NA Laryngoscope, 134:3206-3214, 2024.
