A survey of environmental sustainability in Japanese dialysis facilities.

backgroundDialysis practice has a particularly high environmental impact, including responsible for carbon emissions and climate change. Insufficient research has been conducted on environmental sustainability activities in dialysis therapy in Japan.

methodsWe conducted an online Green Survey comprising 30 question items based on a previously conducted survey in Australia. Between August and September 2023, this was sent to members of the Japanese Association of Dialysis Physicians, including hospital and clinic physicians, working across 885 dialysis facilities in Japan.

resultsIn total, 255 (29%) facilities responded to the survey. More than half of the facilities (n = 157; 61.6%) responded that they did not have a strategy, policy, or action plan for environmental sustainability. In four-fifths of the facilities (n = 208; 81.6%), no "green team" or committee had been formed to promote environmental protection. By contrast, most of the surveyed facilities had emergency strategies for natural disasters, such as covering for patient visits and staff commuting during extreme weather conditions (n = 169; 66.3%), water shortages (n = 159; 62.4%), and power outages (n = 188; 73.7%).

conclusionsFollowing the UK, Australia and New Zealand, and Portugal, this is the fourth Green Survey to be conducted, and the first on environmental sustainability among kidney health-care providers in Japan. The results indicated that daily activities for environmental protection are still lacking at many facilities, even though the management of dialysis treatment during a natural disaster is well conducted.
