There were 22, 579 aliving patinets under chronic dialysis treated in about 950 dialysis centers at the end of 1977. 17, 311 patients out of 22, 579 were treated in daytime, 4, 887 patients of all were treated in the evening or at night, 116 patients were treated at home and 259 patients were treated with peritoneal dialysis.
Patients number per one million population was 199.4. This number is the largest number in the world. In Japan, the national health insurance system has been well developed, so that all charges of dialysis treatment is covered by the insurance.
From October 1972, the above mentioned health insurance system made significant increase of chronic dialysis patients. According to the statistical data which were researched by Jinko Toseki Kenkyu Kai (Japanese Society of Dialysis Therapy), they suggest us that the final total number of chronic dialysis patients in Japan will reach to approximatly 90, 000.
Survival ratios of chronic hemodialysis patients are as follows; 1 year survival ratio 84.81, 2 years 77.9%, 3 years 73.9%, 4 years 73.3% and 5 years 53.1%. These data were researched from 20, 239 patients treated from January 1972 to December 1976.
Percentage of full time rehabilitation of those patients were 29.9 and partial rehabilition, including 4 to 2 days per week work were 30.8.
About 200 billion yen ( about one billion US$) of total financial charges for this treatment were spent in one year. This large amount of medical charges becomes big economical problems as well as social problems.
