Climate change has been described as ‘the biggest global health threat of the 21st century’.1 Medical professionals have a vital role in mitigating the impact of healthcare systems on the environment and protecting vulnerable people through the development of sustainable clinical practices.
We have previously written about how gastroenterologists must act now to change our endoscopy practice and make it more aligned with core principles of environmentally sustainable healthcare. But it is clear there is a significant lack of evidence to accurately define the scope of the environmental impact of gastroenterology services, or models of best practice to shape policy and move the field in a new direction.
This article aims to provide a framework for us to design and implement quality improvement projects (QIPs) in gastroenterology as a strategy to deliver a more sustainable future in line with the National Health Service (NHS) Net Zero targets.2 Mortimer et al have described the key principles required,3 4 and we aim to apply these to a gastroenterology context and specifically endoscopy services.
The triple bottom line
The value of a healthcare intervention relates to the outcomes delivered against its cost, and the benchmark for cost-effectiveness set by the National Institute for Health and Care Excellence is £20–30 000 per quality-adjusted life year gained.5 However, economists interested in sustainability recognise that costs also need to recognise the social and environmental impact of what is consumed: the so-called ‘triple bottom line’.6 Value can thus be presented using this schematic formula as described by Mortimer et al 3:
Value=outcomes for patients and populations/environmental+social+financial impacts.
Considered in this way, every healthcare intervention has not only financial implications, but also a social cost on the patient and their family/carers, and environmental implications from resource use and carbon footprint, against which the clinical benefit needs …
