Today, well over 160,000 patients undergo dialysis throughout Japan. The number of patients who are newly required to receive it is increasing year by year. Given that situation, our hospital has annually held a seminar since October 1994 for patients with renal diseases. The purpose is to slow the deterioration of renal function and to delay the introduction of dialysis by encouraging the patients to acquire a habit of taking high calory, low protein food.This seminar must have help the patients get more knowledgeable about morbidity and learn the benefit of low protein rice-based diet. Now that three years have passed since the opening of the course, we reviewed the outcome, comparing the effects of old and new restrict diets.A difference began to appear 9-2 months after the lst seminar between the seminar participants and the non-participants (control group) who received guidance only at the outpatient ward. The average rate of decrease in the serum creatine level of those participants who eated lowprotein rice was 0.029 and that of those participants who did not eat the restricted food was 0.166 (p <0.05), compared with 0.262 in the control group. We concluded that the difference is ascribable to the effect of the seminar. We would like to contribute to the well-being of the patients by enriching the content of the seminar and continuing to hold it.
