WCN26-4655 50-YEAR TREND OF THE INCIDENCE OF CHRONIC DIALYSIS PATIENTS IN THE OKINAWA DIALYSIS STUDY (OKIDS) REGISTRY (1971-2020)

We have been studying a community-based dialysis registry in Okinawa (Okinawa Dialysis Study, OKIDS), Japan, since the beginning of dialysis therapy in 1971. We reported the increasing trend of dialysis patients up to 2000 (Kidney Int 2002; 61: 668-675). However, it has not yet studied in the recent 20 years (2001 to 2020). Okinawa prefecture is located southernmost part of Japan and consists of isolated islands. Therefore, most dialysis patients remain within the district.
