Survival data have been compiled on 302 patients undergoing chronic intermittent hemodialysis in 14 centers. This represents approximately one third of the total dialysis population in the United States as of the closing date of the study, June 1967. Fifty-three patients have been observed for 2 or more years. Forty-eight patients have died. The survival rate after 1 year on dialysis was 87%. Two- and 3-year survival rates were 77.3 and 67.4%, respectively. Computed 7-year survival rate is 57.8%. Males and females survived equally well on dialysis.
The group over the age of 46 had a higher fatality rate at the 1-, 2- and 3-year intervals; however, cumulative survival rates were not significantly different between the under 45 and over 46 years groups at the 1-year level ( P > 0.05 ). The survival curve describes a constant geometric function with time, indicating that prognosis neither improves nor worsens for the population over a 3-year period on dialysis. This phenomenon is not unique, having been described in a number of other chronic diseases.
Given the premise that these patients represent a population in a fatal situation were it not for the therapy they were receiving, chronic intermittent hemodialysis appears an effective means of prolonging the life of the uremic patient.
