A nationwide statistical survey of 3, 932 dialysis facilities was conducted at the end of 2004 and 3, 882 facilities (98.73%) responded. The population undergoing dialysis at the end of 2004 was 248, 166, an increase of 10, 456 patients (4.4%) from that in 2003. The number of dialysis patients per million was 1, 943.5. The crude death rate of dialysis patients from the end of 2003 to the end of 2004 was 9.4%. The mean age of patients who underwent dialysis in 2004 was 65.8 years, and that of the total dialysis population was 63.3 years. The percentage distribution of patients who underwent dialysis according to the underlying disease showed that 41.3% of patients had diabetic nephropathy and 28.1% had chronic glomerulonephritis.<br>The rate of calcium carbonate usage for hemodialysis patients was 75.1% and that of sevelamer hydrochloride usage was 26.2%. The rate of sevelamer hydrochloride usage does not necessarily have a strong correlation with the dose of calcium carbonate. Patients, who received a high dose of sevelamer hydrochloride tended to have a low concentration of arterial blood HCO3- approximately 15% of hemodialysis patients used an intravenous vitamin D preparation, which was generally maxacalcitol. The longer the patients had been on hemodialysis, the higher the frequency of use of an intravenous vitamin D preparation. When the concentration of blood serum intact PTH was more than 200 pg/mL, the frequency of use of an orally administered vitamin D preparation decreased; instead, that of intravenous vitamin D preparation increased.<br>The percentage of hemodialysis patients who received percutaneous ethanol injection therapy (PEIT) in the facilities surveyed was 1.4%, and it was particularly high for patients who had been on hemodialysis for more than 10 years. The percentage of patients who again received PEIT was 35.0%. The percentage of patients who had been on hemodialysis for more than 10 years and again received PEIT was more than 50%.
