抄録

In 1994, the Japanese Society for Dialysis Therapy conducted a statistical survey of 2, 759 facilities in Japan and received replies from 2, 752 facilities (99.75%). As of the end of 1994, there were 143, 709 chronic dialysis patients in Japan, an increase of 9, 411 patients (7.0%) over a year from the end of 1993. The gross mortality rate was 9.5%, which was the second highest mortality rate since 1983. Logistic regression analysis of an overview of regular dialysis treatment in Japan revealed the factors affecting the one-year survival rate: Kt/V in excess of 1.6; over 5 hours per dialysis session (i.e., more than 15 hours' diaiysis time/week); protein catabolic rate (PCR) in excess of 0.99/kg/day in non-diabetes patients and in excess of 0.7g/kg/day in diabetes patients; less than 6% post dialysis weight loss; 4.0g/dl or more predialysis serum albumin concentration; and a predialysis phosphorus concentration of 4.0-5.0mg/dl. Moreover, the mortality rate is reportedly lower as the percent creatinine generation rate is higher. The same results were obtained from investigation of the factors influencing the frequency of hospitalization.
