Global Dialysis Perspective: Japan

Hemodialysis therapy was first performed in Japan at United States military base hospitals during the Korean War (1950–1953) to treat injured American soldiers with crush syndrome transferred from the combat zone. Encouraged by such experiences, several university hospitals started to offer acute hemodialysis treatment in 1955 and chronic hemodialysis treatment in the early 1960s. The health insurance program started to cover chronic hemodialysis treatment in 1967. Initially, the costs were not fully covered by the program: a 30% to even 50% copayment was required for patients who were not beneficiaries of the public insurance plan. In 1972, the national government started a program that also covered copayment on the basis of the Basic Act for Persons with Disabilities as a result of lobbying activities by patient groups and academic societies. Since then, hemodialysis treatment has become almost free of charge, except for high-income patients (up to 20,000 Japanese Yen [JPY] or approximately United States $200 per month).Typically, the total monthly cost for a patient on maintenance dialysis is approximately 320,000 JPY or approximately United States $3000, excluding any additional fees or medications. The cost consists of the medical management fee, including routine laboratory tests (22,500 JPY per month), and technical fees (21,400 JPY × approximately 14/mo). The reimbursement system is updated every 2 years. In April 2006, the costs for erythropoiesis-stimulating agents were bundled with the technical fees of hemodialysis and with anticoagulant and normal saline for rinsing. Roxadustat has recently been approved and bundled.According to the recent annual report of the Japanese Society for Dialysis Therapy Renal Data Registry (JRDR) (1), a total of 334,505 patients (2640.0 per million people in the general population) are receiving dialysis treatment in Japan as of 2017. In 40,959 incident patients (323 per million people in the general population), the average …
