Abstract
Background: Understanding the financial and environmental impact of clinical pathways is important for designing sustainable services. This study aimed to compare the cost and carbon footprint of sub-Tenon's and topical anaesthesia for cataract surgery, benchmark minimum topical anaesthesia utilisation rates, and quantify the benefits of increased topical anaesthesia usage in the United Kingdom National Health Service (NHS).
Methods: The cost and carbon footprint of products and staffing for topical and sub-Tenon's anaesthesia for cataract surgery were calculated and applied to National Ophthalmology Database audit data. A mainly process-based approach was used to estimate the carbon dioxide equivalent (CO2e) of product production, usage, and waste disposal.
Results: The typical CO2e per case was 0.71 kg for topical anaesthesia and 1.19 kg for sub-Tenon's anaesthesia. Around a third of CO2e was generated by usage of unneccesary equiptment and wasteful practices. The typical cost per case was £14.60-£17.14 for topical anaesthesia, £27.74 for sub-Tenon's anaesthesia performed by an operating department practitioner and £56.15 for sub-Tenon's anaesthesia performed by a consultant anaesthetist. It is estimated that around 25,000 NHS cataract cases could annually be converted from sub-Tenon's to topical anaesthesia, which would reduce the CO2e emissions of services by 12,000 kg while saving £265,000 on product usage and between £63,500 and £773,750 on staffing.
Conclusions: Topical anaesthesia is a cheaper and more environmentally sustainable alternative to sub-Tenon's anaesthesia for cataract surgery. Increased topical anaesthesia usage in cataract services could contribute towards the NHS aspiration of becoming "net zero" by 2040.
期刊介绍：
Eye seeks to provide the international practising ophthalmologist with high quality articles, of academic rigour, on the latest global clinical and laboratory based research. Its core aim is to advance the science and practice of ophthalmology with the latest clinical- and scientific-based research. Whilst principally aimed at the practising clinician, the journal contains material of interest to a wider readership including optometrists, orthoptists, other health care professionals and research workers in all aspects of the field of visual science worldwide. Eye is the official journal of The Royal College of Ophthalmologists.
Eye encourages the submission of original articles covering all aspects of ophthalmology including: external eye disease; oculo-plastic surgery; orbital and lacrimal disease; ocular surface and corneal disorders; paediatric ophthalmology and strabismus; glaucoma; medical and surgical retina; neuro-ophthalmology; cataract and refractive surgery; ocular oncology; ophthalmic pathology; ophthalmic genetics.
