Environmental sustainability is a growing concern to healthcare providers, given the health impacts of climate change and air pollution, and the sizable footprint of healthcare delivery itself. Though many studies have focused on environmental footprints of operating rooms, few have quantified emissions from inpatient stays. This study quantifies solid waste and greenhouse gas emissions (GHGs) per bed-day in a regular inpatient (low intensity) and intensive care unit (high intensity).
This study uses hybrid environmental life cycle assessment (LCA) to quantify average emissions associated with resource use in an acute inpatient unit with 49 beds and 14,427 hospitalization days and an intensive care unit (ICU) with 12 beds and 2536 hospitalization days. The units are located in a single tertiary, private hospital in Brooklyn, NY, USA.
Results and discussion
An acute care unit generates 5.5 kg of solid waste and 45 kg CO2-e per hospitalization day. The ICU generates 7.1 kg of solid waste and 138 kg CO2-e per bed day. Most emissions originate from purchase of consumable goods, building energy consumption, purchase of capital equipment, food services, and staff travel. . .
