title: Effect of educational hospitalization on chronic kidney disease (CKD) patients.
abstract: Although dietary control is recommended to chronic kidney disease (CKD) patients, improvement of compliance and education of outpatients are very difficult. The purposes of the present study are to estimate the dietary intake of sodium (Na) and protein by measuring urinary Na and urea nitrogen (UN) excretion, and to evaluate the efficacy of educational hospitalization.
  
  
  METHODS
  70 patients (41 men and 29 women) with a mean age of 58.7+/-15.8 years participated in the present study. Most patients had chronic kidney disease (CKD, Stage 3 or 4). Patients were hospitalized to learn about their diseases and dietary restrictions for 1 week. Patients were given low salt (less than 6 g/day) and low protein (0.6-1.0 g/standard body weight kg/day) diet. 24-hour urine samples were collected at the start (Day 2) and on completion (Day 7) of hospitalization. Salt and protein intakes were estimated using patients' 24-hour urine samples.
  
  
  RESULTS
  Estimated salt intake was significantly decreased on completion of the hospitalization (Day 7) (p < 0.05). Estimated protein intake was also decreased slightly, but this was not statistically significant. There were significant differences in the changes of body weight, body mass index (BMI), and systolic and diastolic blood pressure between the start (Day 2) and completion (Day 7) of hospitalization. 89% of the patients showed an improved blood pressure without changes of antihypertensive drugs.
  
  
  CONCLUSIONS
  It appears that short-term hospitalization is an effective program for achieving dietary and blood pressure control in CKD patients.
