Environmentally sustainable kidney care through transplantation: Current status and future challenges

The environmental impact of healthcare is an issue currently examined with increased scrutiny and on a global scale with multiple stakeholders seeking to identify the appropriate interventions to reduce it. Interestingly, a significant portion of healthcare's environmental impact stems from intensive modalities of treatment for chronic disease. There is no better example than End-Stage Renal Disease (ESRD), where dialysis or transplantation are the modalities of treatment offered to the vast majority of these patients. Kidney transplantation (KTx) offers a longer life expectancy and improved quality of life in comparison to dialysis. Cost-effectiveness analyses have proven its financial superiority, as well. PubMed and EMBASE literature search using keywords “kidney transplantation”, “carbon footprint”, “sustainability” showed that there is no published work in the field of environmental sustainability in kidney transplantation. Relevant literature was identified for surgical services and applied to transplantation. Assuming its environmental superiority to dialysis, maximising KTx rate would be an important action towards “green” renal care services. That could be achieved through living organ donation, systematic use of machine perfusion for extended criteria deceased donors and individualised immune risk stratification techniques. All these measures aim towards implementing enhanced recovery protocols and two vital steps can be taken towards assessing their value. The first step is a detailed audit of the environmental impact of these novel techniques and secondly their impact in reducing the length of hospital stay and its subsequent environmental impact. Another key element is delivering appropriate post-operative care, substituting allograft biopsy with non-invasive techniques and reducing physical outpatient follow-up, using telemedicine. The gap in quantifying KTx services environmental impact needs to be addressed urgently, with development of strategies within the multidisciplinary transplant team. Introducing novel technologies can lead to donor pool expansion and improved organ utilisation rates, transforming transplant services in “green” hubs.
