No more waiting: 10 tips to turn kidney transplantation green

To date, the environmental impact of kidney transplantation has received much less attention than that of dialysis. Facilitating a pre-emptive transplant is probably one of the most environmentally friendly interventions available in kidney care, as it avoids dialysis, with its requirements for water and energy. However, transplant assessment also requires scrutiny, as it involves a multitude of tests, often with duplication of tests and sometimes with little, if any, evidence (e.g. cardiac testing of asymptomatic patients). Organ retrieval often involves air travel of either the organ or a surgical team, although more innovative approaches, such as drone transport, are being tested. Transplant anaesthesia also has an environmental footprint linked to volatile substances. Surgical tray optimization is well established in other surgical specialties to reduce the effects of repeatedly sterilizing instruments that are only rarely used. Post-transplant patients have a lot of regular blood tests, and it is time we scrutinise those and find a better balance between safe care and environmental footprint. Virtual appointments have become much more common since the COVID-19 pandemic and we should use them where appropriate, for example in long-term care of stable transplant patients. Transplantation is a very research-oriented specialty, and this also has an environmental footprint that is amenable to intervention. In addition, our congresses and conferences have an environmental footprint, and it is for us to promote meetings with just as much learning and interaction but less travel, waste and energy use. The opportunities are there for us to take and our tips provide ideas for clinical teams to turn kidney transplantation into a showcase for excellent, safe and environmentally friendly care in nephrology.
