The Environmental Footprint of Neurosurgery Operations: An Assessment of Waste Streams and the Carbon Footprint

Healthcare in England generates 24.9 million tonnes of carbon dioxide equivalents (CO(2)e), equating to approximately 4% of the total national output of greenhouse gases (GHG), and of this, 10% is from the manufacturing of medical equipment. Operating theatres are a major contributor of biomedical waste, especially consumables, and are three-to-six times more energy intensive than the rest of the hospital. This study seeks to quantify and evaluate the carbon cost, or footprint, of neurosurgery at a single institution in England. A single neurosurgical operation generates, on average, 8.91 kg of waste per case, equivalent to 24.5 CO(2)e kg per case, mostly from single-use equipment. Per annum, 1300 neurosurgical operative cases are performed with total waste generation of 11,584.4 kg/year and a carbon footprint of 31,859 (kg) CO(2)e. The challenge of achieving net zero GHG presents an opportunity to catalyse innovation and sustainability in neurosurgery, from how care is delivered, through to equipment use and surgical methodologies. This should improve the quality of healthcare provision to patients and yield potential cost savings.

Automated summary

Healthcare in England generates significant carbon emissions, with a considerable portion attributed to the manufacturing of medical equipment. Operating theatres are a major source of biomedical waste and consume significantly more energy compared to other hospital areas. This study highlights the carbon footprint of neurosurgery and emphasizes the potential for innovation and sustainability in this field.
