Abstrakt: Background and Purpose: The rise in hip and knee arthroplasty for osteoarthritis requires addressing healthcare system pollution to support Ireland's climate change goals. This research aimed to quantify waste generated and determine environmental and economic impacts to promote sustainable strategies in joint arthroplasty and shed light on the suboptimal waste management practices.
Methods: The study was conducted at National Orthopaedic Hospital Cappagh (NOHC), measuring waste generated during hip and knee arthroplasty. Clinical, domestic, and recycled waste weights were recorded, including the segregation of Central Sterile Supply Department (CSSD) Blue Wrap waste in ten operations. Kilograms of carbon dioxide emissions (kgCO 2 e) and disposal costs were calculated.
Results: In a sample of 100 joint arthroplasty operations, the study found that revision knees produced 23.58 ​kgCO 2 e per case, revision hips 23.50 ​kgCO 2 e, primary knees 15.82 ​kgCO 2 e, and primary hips 14.64 ​kgCO 2 e. CSSD Blue Wrap contributed on average 13.5% of OT waste. Extrapolating these findings to the estimated number of joint arthroplasties performed in 2022 ​at NOHC (1556 hip and knee joint arthroplasties), the emissions were estimated to be 24,576 kgCO 2 e, with the cost of disposal up to €29,228. Strategies to mitigate this waste have been identified and proposed.
Conclusion: The research aimed to address the environmental impact of orthopaedic joint arthroplasties, offering strategies to reduce waste generation, carbon emissions, and cost. Utilising our methodology to calculate greenhouse gas emissions will empower sustainability offices to conduct their own waste audits and implementing our strategies for waste management practices can help minimise environmental waste.
