Background: Contact precautions were used during COVID-19 to reduce nosocomial transmission, though these practices have environmental impacts. We sought to examine the effect of de-implementing contact precautions in a regional healthcare system. Methods: We utilized the electronic medical record to identify all hospital-onset COVID-19 cases among hospitalized patients in nine regional hospitals from Results: There were 88,963 patient-days of isolation during implementation, and 23,378 patient-days of isolation after implementation. Conclusions: Despite de-implementing glove/gown use, we observed no increase in HO COVID-19; however, we benefited from a considerable decrease in both global warming potential and waste.
