Abstract
After excluding anaesthetic gases, around one-third of carbon emissions from surgical procedures are from consumables. This sustainable quality improvement project revised the laparoscopic appendicectomy surgical set at a large teaching hospital, with the aim of reducing unnecessary usage of disposable laparoscopic ports and surgical instruments. A prospective audit of 25 consecutive laparoscopic appendicectomies (5% of annual appendicectomies performed at the Trust) was conducted to assess use of disposable instruments. The financial and environmental costs of the five most commonly used disposable instruments were calculated and annual cost of current practice determined. A revised surgical set was created to include additional reusable instruments and new reusable ports. A reaudit of disposable surgical instrument usage was conducted and the financial and environmental impact of the new set compared with the results from the initial audit. A total of 109 disposable instruments were opened in 25 appendicectomies, costing an estimated £49,656 and 692kg CO2 equivalent (CO2e) annually. Following rollout of the revised appendicectomy set, there was a significant reduction in disposable instrument usage (median four versus one instruments per case, p<0.00001). The revised set is predicted to reduce annual disposable instrument usage from 2,180 to 705 instruments (68% reduction), saving £219,452 and 3.02 tonnes CO2e over the estimated seven-year lifecycle of the reusable instruments. Updating a laparoscopic appendicectomy set to include additional/new reusable instruments can lead to a marked reduction in disposable surgical instrument usage. This results in significant projected financial and CO2e savings.
