Presentation Description
Institution: John Hunter Hospital, Newcastle - New South Wales, Australia
Aim: Each hospital produces an estimated 1.5 billion kilograms of solid waste annually. A large generator of waste in ENT is in the clinic, with many disposable instruments and PPE being used. We aimed to determine how much disposable equipment was being used by a public hospital ENT Clinic.
Methodology: The disposable waste normally thrown into the bin was collected over 10 ENT clinics where the patient was seen by a doctor (senior resident, registrar or consultant) and recorded. Sharps were not collected.
Results: Over 10 clinic sessions, 147 patients were seen. 117 single use gloves, 129 ear speculums, 54 nasal spray nozzles, 49 micro-suckers, 23 tongue depressors, 24 suction connectors, 14 wax-curettes, 13 Thudicum speculums, 13 alligator forceps and 8 syringes were used. This generated 244 pieces of plastic packaging. 65 reusable scopes were sterilised using Tristel wipes, consuming another 390 single use gloves. The use of gloves alone generated 13182g (90g per patient) during the audit which equates to 395 kg of CO2 emissions annually, equivalent to driving 2100km. The audit process generated discussion on how to reduce waste in clinic and ensuring only necessary equipment is used.
Conclusion: Compared with other industrialised sectors, healthcare is second in total waste behind the food industry, responsible for 8% of greenhouse gas emissions. It is difficult to balance the need for infection control with the production of waste however conscious decision making, such as using hand-hygiene instead of gloving, should be made to reduce our carbon footprint.
