COMPLIANCE IN HEMODIALYSIS-PATIENTS - A MULTIVARIATE REGRESSION-ANALYSIS

Successful treatment of patients with end-stage renal failure requires , in addition to dialysis, strict control of dietary, fluid and medica tion intake. In the present study we measured, in 50 chronic hemodialy sis patients, serum potassium (K), serum phosphate (PO4) and interdial ytic weight gain as indices of diet, medication and fluid compliance, respectively. Dietary compliance did not correlate with fluid or medic ation compliance, whereas fluid intake and medication compliance were related (p = 0.01). Age, time on dialysis, place of birth and whether the patient came accompanied or not to the dialysis unit were the main variables affecting serum K levels. Sex, ethnic origin and education significantly affected serum PO4. Sex, place of birth, marital status, number of children and years of education affected fluid intake. The compliance of the hemodialysis patient with different aspects of his r egimen is thus multifactorial. Attempts to improve compliance and thus reduce morbidity and mortality should be aimed at identifying the pop ulation with low compliance and exposing them to educational programs.
